Endoscopic biopsy channel assembly accessories

During biopsy, the endoscopic biopsy channel is a straight hose. However, accessories passing through the channel may damage or puncture the channel. Additionally, attachments can cause the insertion tube to kink or collapse. Fortunately, sieyutechmed.has an experienced production team and endoscope repair technicians who can help you make the right choice. Please feel free to contact us if you need to order new biopsy channel accessories. We are happy to help.


The third revision of the Society for Gastrointestinal Endoscopy clarifies recommendations for endoscope accessories. These accessories should be cleaned with a sterile, lint-free cloth and sanitized with a high-grade disinfectant or sanitizer. Reusable parts should be rinsed with clean, sterile water. They should also be sterilized before use.

An instrument channel extends from the biopsy port to the proximal end of the endoscope. The biopsy channel includes a straw extending from the distal end to the proximal end of the endoscope. During the biopsy, the sampler pushes the brush into the biopsy port, which is then cut by the facilitator with sterile wire cutters or scissors. The sampler inserts the bristle portion of the brush into the collection tube.

In addition to maintaining sterility, endoscopes should be reprocessed. Reprocessing is recommended according to the manufacturer’s guidelines. It should be performed by a high-quality endoscopic reprocessor that performs an automated reprocessing cycle. This process ensures high reliability, minimizes employee hazards, and reduces scope damage.

Post-processing is critical. Endoscopes must be thoroughly cleaned and disposed of after use. It is recommended to execute before reprocessing. Regardless of endoscope reprocessing, endoscopes must be sterilized to prevent biofilm formation. It is also important to use an approved sterilization process before using the same equipment. This is the most important way to ensure the safety of endoscopes.


Clear endoscope reprocessing procedures are essential to minimize infection risk and improve patient safety. Endoscope reprocessing procedures should include documentation based on the manufacturer’s IFU and should be supported by appropriate infrastructure. Documentation should also include decontamination and sterilization procedures for reusable biopsy forceps and accessories. The toolkit includes example documents that demonstrate how to implement a referral procedure, and can be customized to the specific needs of your facility.

The biopsy channel should be thoroughly cleaned before endoscopy. The endoscope should be wiped thoroughly with a detergent solution. Air is also repeatedly passed through the biopsy channel. If the biopsy channel is not completely cleaned, the endoscope must be transported to a separate room for sterilization. Endoscopes must be stored in airtight containers when not in use.

All instruments used during biopsy should be reprocessed according to recommended procedures. Performing ERCP is riskier than other endoscopic procedures because the small lumen and relatively large diameter of the endoscope make it susceptible to endogenous infection. Therefore, reprocessing procedures should be thoroughly documented and monitored. Facilities should also assign a person to oversee the infection control process and ensure that all staff complete annual competency reviews and infection prevention training.

In both biopsies, an endoscope is used to examine the lining of the digestive tract. This allows doctors to visualize the pancreatic and common bile ducts. The endoscope is inserted through a small incision in the abdomen or mouth. Doctors can also use flexible feeding tubes. However, in cases where oral intake is not possible, doctors may use percutaneous endoscopic gastrostomy.


Incisional biopsies can be performed using rigid or flexible endoscopes. These procedures usually involve the use of tweezers. These forceps can be inserted into the body through auxiliary channels and actuated externally. The endoscopist or assistant performs the biopsy under video control. Afterwards, the biopsy material is removed. This process may take several minutes.

To prepare the endoscope for biopsy, remove the suction valve and air/water valve. Disconnect the biopsy channel rubber stopper and suction valve from the endoscope. Next, soak the endoscope in a detergent solution. When it is completely wet, apply gauze to the tip of the endoscope. For a more thorough cleaning, use a brush to clean the biopsy channel. The brush should be the right size to remove any contamination.
