what is a gastrointestinal endoscope forceps channel?
The instrument channel of a gastrointestinal endoscope is a flexible, precision-engineered hollow tube that serves as a core functional component, providing a safe and stable conduit for instruments such as biopsy forceps and high-frequency electrosurgical knives.
The inner layer features high lubricity and wear resistance to minimize instrument friction, while the outer layer utilizes flexible, collapse-resistant polymer materials to ensure the channel remains unobstructed during complex bending maneuvers.
Its primary function is to facilitate examination, sampling, and minimally invasive procedures during endoscopy—including tissue biopsy, cytology brushing, injection, polypectomy, and foreign body removal.
