Product Description
In the medical device field, an "endoscope sheath" is usually called a sheath or introducer sheath. It is a tubular accessory used together with an endoscope. Its main job is to create and maintain a stable working channel for the endoscope and surgical instruments to enter a body cavity or tract. It also protects the endoscope, helps prevent infection, and supports surgical procedures.

Structure and Types
An endoscope sheath generally consists of a sheath tube and an inner core (or guide needle/dilator). During use, the inner core helps place the sheath tube into the body, after which the inner core is removed and the endoscope is inserted.
Mostly made of plastic, discarded after use. This effectively avoids cross-infection and protects expensive endoscopes from contamination.
Mostly made of metal, commonly used in rigid endoscope surgeries that require repeated disinfection and sterilization.
Functions and Uses
It provides a path for the endoscope to enter and exit, and prevents the endoscope from touching the trocar or surrounding tissue, protecting both the distal end of the endoscope and patient tissue.
Many endoscope sheaths have an irrigation port/channel for continuously infusing fluid during surgery to keep the visual field clear, or for draining waste fluid and smoke.
In procedures such as neuroendoscopy, the sheath tube itself can be used to retract brain tissue or neurovascular structures, creating a working area within a narrow space.
Some complex operating sheaths (such as those used in ERCP procedures) have multiple working channels inside, allowing a cholangioscope and working instruments to be used at the same time.
Specifications and Standards
Endoscope sheaths are subject to strict industry standards (such as YY/T 0842-2011 Medical Endoscopes - Endoscope Accessories - Sheaths), which specify requirements for mechanical performance, sealing, and biocompatibility.
Specifications are usually determined by outer diameter (Fr) and length (cm). Common urology guide sheath sizes include 10Fr, 11Fr, 12Fr, etc., with lengths ranging from 30cm to 110cm.
