Abstract

The invention discloses a negative hand locking rack with gravity supplement function, which comprises the following parts: gravity supplement mechanism, straight-line joint mechanism, shoulder joint mechanism, middle joint mechanism and ball joint mechanism, wherein the straight-line joint mechanism is set on the gravity supplement mechanism with top connecting one end of shoulder joint mechanism vertically through small arm; the other end of shoulder joint mechanism connects one end of middle joint mechanism through big arm; the other end of middle joint mechanism connects ball joint mechanism through front arm; The negative hand locking rack possesses six freedom degrees, which satisfies the orientation need of operation mechanics.

Description

technical field [0001] The invention relates to a medical device. In particular, it relates to a passive manual locking bracket with gravity compensation function that can be flexibly used in laryngeal surgery. Background technique [0002] The positioning problem of a rigid body in any pose in space is ubiquitous in various industries such as industry, agriculture, and medical treatment. The early positioning brackets were mostly used in industrial production, and they were mostly driven by electric, hydraulic, or pneumatic methods. Although this type of bracket has the characteristics of high rigidity and strong bearing capacity, its structure is relatively complicated and bulky, and it is not suitable for manual operation. . In recent years, with the development of surgical technology, especially the maturity of minimally invasive surgical technology, surgical operations urgently need simple structure, convenient operation, safe and reliable positioning brackets, which ...
