Description

Technical Field

[0001] This utility model relates to the field of endoscope working sleeves, specifically to an adjustable-spacing endoscope working sleeve. Background Technology

[0002] Due to its advantages of minimally invasive surgery, such as less trauma, less pain, and faster recovery, the concept of "minimally invasive" has been deeply integrated into various fields of surgery. Minimally invasive surgery refers to surgery performed using modern medical instruments such as laparoscopes and thoracoscopes through minimally invasive channels and related equipment.

[0003] Minimally invasive surgeries performed using endoscopes are becoming increasingly common. Existing patent CN202322742888.3 discloses a V-shaped dual-channel working cannula, including a connecting handle with a connecting tube. The connecting tube has an instrument channel and an endoscope channel, both arranged in a V-shape. The smaller end of the endoscope channel has an extended tongue-shaped protective device. In use, surgical instruments are inserted through the instrument channel, and the endoscope through the endoscope channel. However, both the instrument and endoscope channels are fixed, limiting the movement space of the instruments and endoscope, resulting in poor adaptability for complex surgeries. Therefore, we propose an adjustable-spacing endoscope working cannula to increase the movement space of the surgical instruments and endoscope, improving adaptability. Utility Model Content
