Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] see figure 1 , an endoscope handwheel locking mechanism provided by the present invention mainly includes a handwheel locking assembly 100 , a handwheel angle assembly 200 and a main shaft 300 .

[0028] The hand wheel angle assembly 200 is placed on the main shaft 300, and its specific arrangement method is: open a through hole in the middle part of each internal part, and then the main shaft 300 passes through the holes on each part of the hand wheel angle assembly 200 in turn. Through holes, each component on the hand wheel angle assembly 200 is sequentially stacked on the main shaft 300 .

[0029] When the handwheel angle assembly 200 is subjected to external pressure, it will move down a certain distance along the main shaft 300 and...

Abstract

The invention discloses an endoscope hand wheel locking mechanism. The locking mechanism comprises a hand wheel locking assembly, a hand wheel bend assembly and a main shaft; the hand wheel bend assembly is arranged on the main shaft; the hand wheel locking assembly is connected with the main shaft in a rotatable manner; and the hand wheel locking assembly rotates on the main shaft to lock the hand wheel bend assembly. The endoscope hand wheel locking mechanism is easy to produce and machine and low in cost.

Description

technical field [0001] The invention relates to the field of medical machinery, in particular to a handwheel locking mechanism for gastrointestinal endoscopes. Background technique [0002] The operating handle of the medical gastrointestinal endoscope is equipped with a curved hand wheel, which is used to control the bending action of the end of the endoscope lens. The medical staff can maintain the bending angle of the end of the endoscope lens through the handwheel locking mechanism so that the doctor can better Observed. [0003] At present, the structure of the handwheel locking mechanism in most gastrointestinal endoscope products in China is very complicated, and the processing cost is very high. Contents of the invention [0004] The present invention provides an endoscope handwheel locking mechanism in order to solve the problems of the above-mentioned handwheel locking mechanism with a very complicated structure and high processing cost. [0005] In order to ac...
