HOW TO USE DISPOSABLE BIOPSY FORCEPS(2023年10月08日)

leomed — 2023-09-21T15:40:59+0900

https://www.leomed-med.com/how-to-use-disposable-biopsy-forceps.html

Disposable biopsy forceps enter the human body through endoscopic forceps, its head is aimed at the lesion, open the mouth of the forceps and press the handle slider to close the collected tissue, close the forceps mouth, pull the handle slider to pull the outer tube backward, and take out the sample Just clip. Let's learn how to use single use biopsy forceps.

Ⅰ. The application of disposable biopsy forceps

Disposable biopsy forceps are suitable for endoscopic sampling of gastric and duodenal biopsies.

Ⅱ. Features of disposable rigid biopsy forceps

1. The product has been sterilized and does not need to be sterilized before use.

2. The biopsy forceps head is made of medical stainless steel.

3. It adopts laser welding and the connecting rod is reliable.

4. It is produced by a purification factory and shipped after strict inspection to ensure product quality.

5. It is configured with various specifications.

Ⅲ. The use of disposable biopsy forceps

1. Open the product package and take out the disposable biological biopsy forceps.

2. The disposable biopsy forceps extend to the abdominal surgery site through the endoscope, move the handle to the root of the handle, and then put all the disposable biological sample forceps into the endoscope, and gradually remove the diseased tissue removed by the forceps according to the needs of the operation.

3. Take out the diseased tissue removed by the forceps, and then take the disposable biopsy forceps out of the body.

The types of disposable biopsy forceps are divided into standard type, side opening type, front-end needle type, round cup shape, tooth cup shape and so on. Mainly connected by laser welding, laser welding can be achieved by continuous or pulsed laser beam.

The laser irradiation heats the surface to be processed, and the heat from the surface is diffused into the interior by thermal conduction. By controlling the laser parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool.

The energy conversion mechanism is completed by the "small hole" structure. When the biopsy forceps screw breaks, it cannot be repaired by conventional welding, and the metal develops thorns. In recent years, most biopsy forceps adopt a rigid four-bar linkage structure, which makes the use of biopsy forceps more convenient.

The key to using a disposable biopsy forceps is to have the strength at hand, and most people are used to the ring finger, middle finger, index finger and thumb combined with the biopsy forceps. The biopsy forceps must be used with moderate force, and the switch should not be too forceful.

This not only does not apply forceps well to the diseased tissue, but also easily damages the biopsy forceps. Its maximum tensile strength is 10kg, and the upper and lower dead points are clear, which is in line with doctors' usage habits.

It is produced in a sterile factory, and the disposable biopsy forceps are strictly checked for sterility before leaving the factory. After the aseptic packaging is opened, each person clamps immediately to completely eliminate cross-infection, which is safe and convenient.

HOW TO USE BIOPSY FORCEPS?(2023年10月07日)

leomed — 2023-09-21T15:40:24+0900

https://www.leomed-med.com/how-to-use-biopsy-forceps.html

In recent years, endoscopy equipment and personnel have been popularized. Biopsy forceps are endoscope accessories that directly manipulate mucosal tissues. They need to meet the standards. However, due to the incomplete use of biopsy forceps, the general effect is not obvious. Accompanying care for cross-infection caused by hospitals is getting more and more attention.

Therefore, it is necessary to find a good sterile method of endoscope accessories and supplies to prevent nosocomial cross-infection. The sterility of endoscopes and their accessories is getting more and more attention. If you use disposable biopsy forceps, you can completely eliminate the possibility of cross-infection. Let's learn about the structure of the biopsy forceps and the correct use and methods!

Ⅰ. The structure of biopsy forceps china

Front end: The front end is composed of two openable and closable cup-shaped pliers valves.

Forceps body: The body of the endoscopic biopsy forceps is composed of a stainless steel threaded tube with a metal wire that switches and pulls the mouth of the pliers. Due to the special structure of the threaded tube, tissue blood and other substances are easy to enter the inside, but it is not easy to clean completely, and it cannot be cleaned completely. The biopsy forceps endoscopy are inconvenient to operate and cannot be opened and closed smoothly.

Operating handle: The ring of the operating handle is used to cover the thumb, and the wide circular groove is used to place the index finger and the middle finger. Under the operation of these three fingers, the force is transmitted to the pliers valve through the pulling wire to open and close.

Ⅱ. Key points of biopsy forceps uses

Biopsy forceps in operation and maintenance will affect the use of endoscope, so need to pay full attention to.

1. Pre-inspection: Make sure that the endoscopy forceps are processed before use and used within a certain period of time. Before inserting the forceps channel of the endoscope, it is necessary to check the opening and closing of the forceps valve.

The specific method is to knead the biopsy forceps itself into a large circle (the diameter of the circle is about 20 cm), and perform multiple opening and closing actions to observe whether the opening and closing of the forceps flap is smooth. If you have 1-2 times of discomfort, generally do not use this biopsy forceps.

Next, you need to check the degree of closure of the biopsy forceps. Hold the thin paper like letter paper and clamp it with the biopsy forceps. The thin paper will not fall off. It is necessary to observe again whether the two cup openings of the pliers flap are completely aligned. If there is any deviation, please stop using it immediately. Otherwise, the pliers tube will be injured.

2. Precautions during operation: Before inserting the forceps tube, the mouth of the biopsy forceps flap should be closed, but don't forget to close too hard, the traction wire may be stretched, affecting the opening and closing of the forceps flap.

When inserting the trachea, please enter along the opening direction of the trachea with the forceps and do not rub against the mouth of the trachea. If there is resistance when entering, please release the angle button and enter in the state of natural stretching as much as possible. If it still fails to pass, please take the endoscope out of the body for testing, or replace other biopsy forceps with a thinner type.

The above is the structure of the biopsy forceps and the correct use and methods. In order to open and close the valve of the biopsy forceps freely, it is necessary to frequently add lubricating oil to the joints, but pay attention to the type of oil such as paraffin oil, and do not forget to use the endoscope housing Of silicone oil. After applying the lubricating oil, please wipe off the excess oil, only keep the lubrication in the joint of the biopsy forceps, and do not be included and exposed.

DO YOU KNOW HOW TO USE POLYP SNARE?(2023年10月06日)

leomed — 2023-09-21T15:39:55+0900

https://www.leomed-med.com/do-you-know-how-to-use-polyp-snare.html

Polyp snare is one of common gastrointestinal endoscopy accessories in therapeutic endoscopy. It's mainly used in digestive polypectomy, protrusion lesion, flat disease, even removal of early carcinoma of digestive tract (such as EMR, MBM, etc.).

Besides, there are applications with similar principle, such as gastrolith lithotripter, net which taking out foreign matter, accessory helping superfine endoscope enter biliary tract for observation and treatment operation, as well as ERCP net and urgent endoscope.

Ⅰ. Composition of polyp snare

With a long history in TCRP, polyp snare is most widely used and classic. Through continuous development, the materials and technology of polyp snare continue to improve, combining with demands of endoscopy doctor, its kinds begin to boom.

Electric polyp snare is mainly composed of handle, snare core and outer sheathing canal. The function of polyp snare mainly focuses on snare core. According to different shapes of polyp snare cores, there are circle (rigid oval), oval (soft oval), spiral coil oval, semicircle, hexagon, and other shapes.

Polyp snare core uses steel wire material, for the ease of conduct electricity and with strong tension, which can realize good effect of tightening removal in the ESD polypectomy.

Ⅱ. How to use polyp snare?

Besides, matters that need your attention are: the bigger the contact area of polyp snare for energizing, the better and steadier the cutting effect is, meanwhile, combining with anti-slip effect, steel wire uses spiral knitting, like a little girl's braid, so that polyp snare has enough contact with polyp and has anti-slip effect.

For special circumstances when some parts cannot be extracted, such as lesser curvature of gastric body, duodenal papilla and sigmoid colon lesion, half-moon polyp snare can be used for extracting, and generally combine with transparent cap for cutting.

Adenoma at duodenal papilla needs tip of polyp snare as fulcrum to fix snare and extract polyp for cutting after opening.

Ⅲ. Classification of polyp snare tip

There are two kinds of polyp snare tip, one is tip bending (non-standard name) and the other is tip insulation.

Tip bending contributes to polyp snare' s good natural opening force when it unsheathes, meanwhile, contributes to complete extracting of target area when special lesion and part, which cannot be extracted, are fixed by tip and open snare.

Tip insulation is hardly used; however, we have to know that this kind polyp snare tip can avoid accidentally injure or punching, especially suitable for weak mucosa.

Pliable tip loses function of fixing polyp snare at certain degree, so it has small risk but also is not easy to control, which is the defect.

WHAT IS THE SIGNIFICANCE OF USING ERCP GUIDEWIRE IN RETROGRADE CHOLANGIOPANCREATOGRAPHY?(2023年10月05日)

leomed — 2023-09-21T15:39:22+0900

https://www.leomed-med.com/what-is-the-significance-of-using-ercp-guidewire-in-retrograde-cholangiopancreatography.html

As a commonly used endoscopic device, guide wire is the lifeline of difficult ERCP surgery. Flexible application of guide wire can not only shorten the operation time and improve the success rate of intubation, but also reduce the occurrence of complications.

1. The use of ERCP guidewire can be used for smooth angiography

The guide wire has the functions of no tissue damage, elastic front end, and very smooth when wet, so it can enter the bile duct or pancreatic duct and pass through the stenosis or obstruction by exploring the cavity of the bile duct or pancreatic duct, and guide the accessory to improve the success rate, thereby successfully imaging.

2. The use of ERCP guidewire can save time for other treatments and relieve the pain of patients

If the guide wire is directly inserted into the incision knife for intubation, the nipple incision can be performed immediately after angiography, so that the incision knife is not easy to slip out and avoid repeated intubation.

After exiting the scalpel and keeping the guide wire in the bile duct or pancreatic duct, other treatments can be performed. The flexible application of ercp products guide wire can significantly improve work efficiency and success rate.

3. Use the ERCP guidewire to guide the accessory into the target position

Behind the front end of the guide wire is a steel wire. The strength of the guide wire can be used to increase the insertion force and guide accessories (brackets, mesh baskets, etc.) into the target position.

For patients with too small nipples, displaced nipples after surgery, or with diverticulum beside the nipples, the guide wire can be indwelled in the pancreatic duct and the nipple can be controlled in the center of the field of view to make intubation in the direction of the bile duct easier.

During EST, the direction of the nipple can be changed by placing the ERCP guidewire in the bile duct to avoid damage to the edge of the diverticulum during EST, while controlling the incision speed and adjusting the incision direction in time to achieve an ideal incision effect.

In the process of EST, there may be duodenal mucosal annular folds above the nipple or when the nipple position is relatively biased and cannot be completely incised, the guide wire can be placed in the bile duct to change the direction of the nipple to avoid bleeding and perforation happened.

The placement of a guide wire in the bile duct or pancreatic duct during calculi facilitates the entry of stone removal instruments into the bile duct or pancreatic duct, facilitates stone removal, and reduces the chance of stone incarceration for beginners.

4. The application of ERCP guidewire can reduce the occurrence of pancreatitis

Pancreatitis after ERCP is a common complication, mainly due to the excessive injection of contrast agent too fast, the high pressure in the pancreatic duct, and the obstruction of pancreatic juice drainage.

If it is difficult to insert the nipple, and the pancreatic duct is repeatedly inserted to cause edema and injury, pancreatitis occurs. Using the guidewire technique can avoid excessive injection of contrast agent into the pancreatic duct and prevent pancreatitis.

In addition, the direction of the biliopancreatic duct can be judged by the direction of the guide wire of the ercp product based on the X-ray-opaque property of the guide wire, rather than the injection of the contrast agent;

The soft and hydrophilic properties of the guide wire tip make it less damaging to the biliopancreatic duct wall, thereby reducing the occurrence of cholangitis and pancreatitis.

ERCP and related techniques (such as endoscopic papillotomy, endoscopic stone removal, endoscopic nasobiliary duct placement and drainage, biliary stent implantation, etc.) are currently one of the main methods for the diagnosis and treatment of biliopancreatic diseases.

Through this technology, countless patients with pancreatitis and obstructive jaundice have been diagnosed and effectively treated. This technology has relatively high difficulty and certain risks in endoscopic minimally invasive technology. The full application of new guide wire technology can improve the success rate of angiography and improve the efficiency of the angiography. The treatment success rate is significantly improved.

The use of ERCP guidewire pathfinding can significantly reduce the occurrence of pancreatitis, reduce the operation time, relieve the pain of patients, and save medical resources.

WHAT ARE THE CORE COMPONENTS OF BALLOON DILATION CATHETERS?(2023年10月04日)

leomed — 2023-09-21T15:38:51+0900

https://www.leomed-med.com/what-are-the-core-components-of-balloon-dilation-catheters.html

Looking at the corresponding technology of arterial surgery today, it can be found that the balloon dilation catheter has played a particularly important role in it. As the function of the balloon dilation catheter is becoming more and more abundant and the corresponding application situation is becoming more and more popular, the actual properties of the dilation catheter will also be affected by various factors to produce different application effects.

Looking at the honest and reliable balloon dilation catheters nowadays, it can also be found that the functions of this product in practical applications are mostly affected by the following factors.

Ⅰ. The outer diameter of the balloon dilation catheter
It is well known that the outer diameter of the balloon includes many indicators, such as: the outer diameter of the balloon is the main core component of the PTA balloon dilatation catheter, the outer diameter of the balloon through the outer diameter of the push rod, the outer diameter of the balloon, and the outer diameter of the lesion entrance and so on.

The passing outer diameter of the balloon is a commonly used index to evaluate the performance of the balloon. It usually refers to the measurement of the outer diameter of the marked part of the balloon in the unexpanded state of the balloon dilation catheter, and the size of the passing outer diameter of the balloon and the material of the balloon. The folding method and marking technology of the manufacturing process balloon have a certain relationship.

The smaller the number of folded layers of the balloon, the smaller the passing outer diameter of the balloon, and the embedded marking technology is beneficial to reduce the passing outer diameter of the balloon.

Therefore, for general coronary artery disease, the outer diameter of most balloons is sufficient to meet the needs of passing the lesion, but for serious stenosis and calcification lesions and other series of problems, it is more appropriate to choose a single-label balloon with a small outer diameter to pass the lesion more easily.

Ⅱ. Naming and burst pressure of balloon dilation catheter

The other core components of the balloon dilation catheter include the named pressure and burst pressure of the balloon. The named pressure refers to the pressure when the balloon reaches a predetermined diameter, and the burst pressure refers to the pressure when the balloon is inflated and ruptured.

The balloon burst pressure is based on the results of in vitro tests and will not rupture. The named pressure of the balloon dilation catheter and the balloon burst pressure are equally important parameters reflecting the performance of the balloon, and its pressure resistance determines the safe pressure range of the ball when the balloon expands.

From the above content, it can be found that the indicators and corresponding functions of this kind of balloon dilation catheter will have an immeasurable impact on subsequent applications, and customers need to choose honest and reliable peripheral vascular products through professional merchants. Better function as the basis to maintain the follow-up safe operation effect.

Only through this kind of after-sales service to standardize balloon dilation catheter, manufacturers can they bring high-quality products to themselves based on their reliable service quality and increase the success rate of surgery.

WHAT ARE BIOPSY FORCEPS?(2023年10月03日)

leomed — 2023-09-21T15:38:21+0900

https://www.leomed-med.com/what-are-biopsy-forceps.html

What are biopsy forceps
A biopsy forceps is a surgical instrument similar to a pair of scissors. They are used as grasping tools during surgery. A biopsy is done when doctors need to check tissue for disease. By testing the tissue removed during a biopsy, doctors can diagnose patients and determine the most appropriate treatment options, or rule out certain diseases.

1. During surgery, biopsy forceps can be used for fine work

If the doctor's fingers are too large to manipulate the tissue inside the small incision, these endoscopic biopsy forceps instruments will replace the fingers. They can also act as a third hand during surgery. If several pieces of tissue need to be set aside while the surgeon is performing the task with his hands, biopsy forceps will be used to set the tissue aside. Biopsy forceps come in several different designs, each suitable for different surgical situations. There are two basic types: locking and non-locking. Locking forceps are used to grasp tissue and non-locking forceps are used to move tissue.

Locking pliers usually have finger loops that resemble scissors. The most common mechanism that keeps these pliers locked is a set of interlocking teeth near the ring. When the pliers are closed, the teeth lock and keep the blunt blades of the pliers closed. Non-locking pliers have a spring mechanism that keeps the blades open until pressure is applied. They are used to move small objects quickly during surgery. The tips of non-locking tweezers can be blunt or finely serrated.

2. Biopsy forceps can be designed with straight tips or angled shafts

The angled axis provides the surgeon with more reach during the procedure and helps simplify maneuverability. The instrument can also be designed with a rotational axis that allows physicians to manipulate deeper tissues within body cavities without making large incisions.

3. Some important characteristics of biopsy forceps are sterility and durability

Typically, the bioptome instrument is made of high-grade carbon steel. This high-quality steel allows the pliers to withstand repeated sterilizations that occur at extremely high temperatures. Sterilization between procedures is important to prevent the spread of disease between patients.

Other types of biopsy forceps are intended to be used once and then thrown away. These are usually made of plastic. There is some debate about which type of biopsy forceps (single-use or reusable) is better. Some studies have shown that disposable bioptomes yield better tissue samples, but reusable bioptomes are more durable.

SPECIFIC OPERATIONS OF EMR AND ESD AND THEIR DIFFERENCES(2023年10月02日)

leomed — 2023-09-21T15:37:46+0900

https://www.leomed-med.com/specific-operations-of-emr-and-esd-and-their-differences.html

1. Specific operation method of generalized polyp EMR

(1) Polypectomy

That is, submucosal injection-resection method, separate the submucosa, inject liquid, and fully lift the lesion during full submucosal injection. If the lesion is less than 2cm, use a snare to circle it, lift it along the wall, loosen the mucosal muscle layer that may be clamped up, and then remove the lesion with EMR equipment.

(2) Transparent cap method

Transparent plastic caps with different specifications, flat or angled surfaces are installed at the inner lens end to attract and remove the lesions.

After submucosal injection of the lesion under endoscopy, put the endoscopic snare in the groove at the front end of the transparent cap. The transparent cap EMR equipment is aligned with the lesion to be removed and sleeved into the transparent cap. Tighten the snare to cut the lesion. Before electric cutting, loosen the snare slightly to restore the muscularis propria that may be involved to its original position.

(3) The ligation device method

The inner lens is equipped with a ligation device. After aiming at the lesion to be removed and attracting, the rubber band covers the lesion to form a pedicle like polyp, and then the lesion including the rubber band is electrically cut under the rubber band.

This method has the advantages of simple operation, clear visual field, easy to grasp the depth of resection, less local injury, less bleeding and complications, and is relatively safe.

2. The specific operation method of ESD equipment

(1) Mark, use a needle incision or argon ion coagulation to mark the resection area with 0.5cm electrocoagulation at the edge of the lesion;

(2) Before submucosal injection of liquid, the clinically available liquids for submucosal injection include physiological saline, glycerol fructose, sodium hyaluronate and so on.

(3) Pre-cut the surrounding mucosa: use the ESD equipment to cut part of the mucosa around the lesion along the marking point or the outer edge of the marking point, and then use the IT knife to cut all the surrounding mucosa;

(4) According to different parts of the lesion and the operation habits of operators, ESD equipment IT, Flex or HOOK knife and other stripping instruments were selected to peel the lesion along the submucosa;

(5) For wound treatment, argon ion coagulation was used to electrocoagulate all visible small blood vessels in the wound to prevent postoperative bleeding. If necessary, hemostatic clamps were used to clamp the blood vessels.

3. Differences between EMR and ESD equipments

EMR and ESD derived from the same origin and have similar technical characteristics. EMR ESD difference as follows：

The disadvantage of EMR is that it is limited by the size of resectable lesions under endoscopy (less than 2cm). If the lesions are greater than 2cm, it needs to be resected in blocks, the edge treatment of resected tissues is incomplete, and the postoperative pathology is inaccurate.

However, the ESD equipment expands the indications of endoscopic resection. For lesions larger than 2cm, it can also be completely removed. It has become an effective means for the treatment of early gastrointestinal cancer and precancerous lesions.

At present, EMR and ESD are widely used in the resection and treatment of digestive endoscopy.

EMR and ESD technology is the killer of endoscopic resection, and has become an important means of minimally invasive treatment of early gastrointestinal cancer and precancerous lesions. It is believed that EMR and ESD equipment and EMR and ESD endoscopy can create greater medical value for the health of people in the future.

APPLICATION PROGRESS OF POLYP SNARE IN COLORECTAL POLYPS(2023年10月01日)

leomed — 2023-09-21T15:37:09+0900

https://www.leomed-med.com/application-progress-of-polyp-snare-in-colorectal-polyps.html

Ⅰ. Resection technique of polyp cold snare

Cold excision techniques should include biopsy forceps cold excision, cold excision of polyp cold snare, mucosal cold excision and so on. A small snare with a diameter of 1.5 cm should be selected.

Spherical diameter or surface diameter of polyp is less than 1.0cm. To complete the polyp snare, the straightening lens is inflated, the snare is tightened and slightly raised, and clip sutures are required. Polyps can be pedunculated, pedunculated or pedunculated. Polyps can be inflammatory or adenoma in nature.

Hospitalized patients should fast for more than 12 hours, and only eat if there is no perforation and bleeding, and be observed in hospital for more than 24 hours. Outpatients, equivalent to a large specimen of trap biopsy, are sent to the ward for nursing, without fasting, eating liquid food for 12 hours, and observing for 12 to 24 hours.

Ⅱ. Advantages of polyp cold snare resection

1. Convenience and fast healing.

2. Cold excision of suitable polyps is safe, and it is safe to expand when needed. According to literature reports, bleeding and perforation are not easy to occur.

3. Only the polyp snare can be used, eliminating the need for injection needles, electric knives, etc. The deep penetration of electrocution without injection, and the deep penetration of hot tweezers and other treatments.

4. Save costs.

5. The sessile is completely trapped. After the sessile injection, the EMR (EMRC) attracted by the non-transparent cap is not easy to be trapped.

6. It can also operate without an electric knife.

7. The polyp cold snare can be rotated, which is flexible and convenient to use.

8. Suitable for primary hospitals, it can be selected to case promotion.

9. The use of snare is often excision, but the treatment with biopsy forceps instrument is not clear.

10. The snare is more thorough than the biopsy forceps.

11. Those who take mannitol should not use electrosurgery. It is suitable for cold excision of polyps with cold snare. When appropriate, on-site treatment is convenient for patients.

12. A small snare with a diameter of 15mm can measure the size of the polyp, which is helpful for judging whether the polyp resection condition is sufficient.

Ⅲ. Precautions for polyp cold snare excision

1. Large polyps are limited.

2. Suitable for EMR and ESD endoscopy, mature and complete EMR or ESD removal technology can be selected.

3. The pedicle polyp can also be directly trapped for electric cutting, not fine and special cold cutting, and the inside of the pedicle is left, and the clip can hold the root.

4. The usual snare can also be used, and the special thin polyp snare is more suitable for cold cutting.

5. The cold excision in the literature is invalid, and the electric excision is not directly trapped, and finally changed to EMR.

6. Pay attention to complete excision.

The incidence and mortality of gastrointestinal cancers such as colorectal cancer remain high. The morbidity and mortality rates are among the top cancers, and timely inspections should be made if necessary.
