Combined positioning mechanism, instrument clamping hand and surgical robot using it

Abstract

The invention relates to a combined positioning mechanism, an apparatus clamping manipulator with the same and a surgical operation robot. The combined positioning mechanism can realize three functions through one clip: under the cooperation of a locking mechanism and a positioning shaft, clamping equipment to be fixed, contracting a rotating connecting piece to the inner part of a base housing and locking a zero position. The combined positioning mechanism disclosed by the invention belongs to a pure mechanical structure, quick positioning and fixed connection between the apparatus clamping manipulator and a base of the surgical operation robot can be realized, the structure is relatively simple, each spare part is easy to process, the equipment cost can be reduced, and the mounting efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a combined positioning mechanism, an instrument clamping hand and a surgical robot using the same. Background technique [0002] Minimally invasive surgical robotic surgery system is a complex integrating multiple modern high-tech means, mainly used in cardiac surgery and prostatectomy. With it, surgeons can operate machines remotely, away from the operating table. Completely different from the traditional concept of surgery, traditional open surgery has a lot of blood loss, while minimally invasive surgical robots have relatively less blood loss; and traditional open surgery requires a long treatment time and slow recovery for patients , while the minimally invasive surgical robot can achieve minimal surgical damage, improve the accuracy and quality of disease diagnosis and surgical treatment, increase the safety factor of surgery, shorten treatment time, and reduce...

AI Technical Summary

Problems solved by technology

Therefore, minimally invasive surgical robots are used more and more widely, but at the same time, there are also some problems. Minimally invasive surgical robots need to complete a series of cutting, hemostasis, suturing, knotting and other tasks in complex operations. action, it is necessary to replace different instrument holders

There are some quick-change mechanisms for the connection between surgical robots and instrument holders on the market, but the replacement process is cumbersome and requires electronic detection and positioning, which is easily disturbed and affects the positioning accuracy. Risks such as contact blockage and reduced sensitivity, so how to improve the positioning and connection structure between the instrument gripping hand and the base of the surgical robot has always been a matter that the industry needs to pay attention to
