Abstract

The invention discloses a medical instrument sheath which is used for being in cooperation with an endoscope for use. The medical instrument sheath comprises a sheath tube and an inner core, wherein the inner core is sleeved with the sheath tube. One end of the sheath tube is connected with an air bag, the air bag wraps the periphery of the end portion of the sheath tube, the sheath tube is provided with an air inflation catheter and a clamping opening, the air inflation catheter is connected with the air bag of the end portion of the sheath tube, and the clamping opening is matched with the endoscope in a locking mode. The air bag is designed on the end portion of the sheath tube, the air bag wraps the end portion of the sheath tube, and the surgical space is expanded through expansion of the air bag. When the medical instrument sheath is in cooperation with the endoscope for use, the endoscope can be protected, the better view and the better space are provided for the observation and a surgery, and therefore the aim of improving the safety rate of the surgery is achieved.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an instrument sheath. Background technique [0002] The rise of minimally invasive medicine in recent years, especially the improvement of interventional technology and interventional devices, has made the application of interventional medicine more and more extensive. Intervention relies on the guidance of medical imaging equipment, uses puncture and catheter technology to diagnose and treat diseases, and is a discipline that focuses on treatment. It has the characteristics of accurate positioning, less trauma, fewer complications, high curative effect, quick effect, and strong repeatability. Interventional therapy has become the third major clinical treatment alongside medical treatment and surgical treatment. [0003] The medical instrument sheaths on the market are used as instruments for intervening in the human body, providing a passage for the endoscope to enter the operating area...
