Hand instruction sensing device of surgical robot

Abstract

The invention discloses a surgical robot hand instruction sensing device, and relates to the technical field of surgical robot instruction sensing. The mechanical arm comprises a sensing mechanism, the sensing mechanism comprises a sensing rotating shaft, an instruction sensing grip is installed at one end of the sensing rotating shaft, a synchronous operation assembly capable of controlling the two mechanical arms at the same time is installed in the instruction sensing grip, and a pressure adjusting assembly used for adjusting finger pressing stress is further installed in the instruction sensing grip. Through the structural design, the device can simultaneously control opening and closing of two surgical instruments by a single hand when operating a robot, control of the surgical instruments does not need to be continuously switched, surgical operation is more convenient and faster, and by pushing a pressure adjusting plate to move in an instruction sensing grip and extruding a reset spring to contract, the surgical instrument can be controlled to be opened and closed by a single hand. Further, the force required for pushing the first holding block and the second holding block can be adjusted, and adjustment can be performed according to the habits of each doctor.

Description

technical field [0001] The invention belongs to the technical field of surgical robot instruction sensing, in particular to a surgical robot hand instruction sensing device. Background technique [0002] Surgical robot is a new type of medical device integrating clinical medicine, biomechanics, mechanics, materials science, computer science, microelectronics, mechatronics and many other disciplines. It is an important development direction of globalization, and has broad application prospects in clinical minimally invasive surgery, field rescue, earthquake and tsunami disaster relief, etc. Existing surgical robots operate by inserting fingers into sensing sleeves, commanding sensing devices to grasp It is inconvenient to hold, and only two surgical instruments connected to the surgical robot can be controlled at the same time. When the remaining surgical instruments need to be controlled, switching is required, and the operation is relatively inconvenient. Contents of the ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a hand command sensing device of a surgical robot to solve the existing problems: the surgical robot operates by inserting fingers into the sensing sleeve, and the command sensing device is inconvenient to hold. And at the same time, it can only control two surgical instruments connected to the surgical robot. When it is necessary to control the other surgical instruments, it needs to be switched, which is inconvenient to operate.
