Description

Technical Field

[0001] The utility model relates to the field of medical device related products, in particular to a disposable medical endoscope stone removal net basket. Background Art

[0002] Passive surgical instruments are instruments that can perform surgical operations without the need for an external energy supply. The disposable endoscopic stone removal basket is a commonly used passive surgical instrument used for endoscopic stone removal surgery. The disposable endoscopic stone removal basket consists of multiple components, including a guide wire, a basket, and a handle. The guide wire is used to guide and manipulate the basket so that it can accurately capture and remove stones. The basket is the main part of the stone removal, with a large holding space and good elasticity, which can effectively capture and fix stones. The handle is used to operate and control the entire instrument;

[0003] However, the existing endoscopic stone removal basket handle structure is mostly an integrated structure. When the operator uses it, the position of the handle cannot be adjusted according to the size of the palm, which makes it inconvenient to operate the driving mechanism on the joystick.
