Fast switch device for correcting unit end

Abstract

The invention relates to a fast switching device on the end of an actuator, comprising three parts as follows: firstly, a switchable actuator is constituted by an end apparatus and a switching mechanism of the end apparatus, wherein the end apparatus is connected with the switching mechanism of the end apparatus, a chamfering hob inclined surface is processed on the top end of the switching mechanism of the end apparatus, a groove with a certain gradient is processed on the upper head part, the lower part of the switching mechanism of the end apparatus takes on a hexagonal prism shape, and is matched with a hexagonal prism on the lower part of a center shaft, secondly, a fast switching mechanism is constituted by an outer sleeve, a spring, an upper sleeve, a center shaft, balls and an upper end button, wherein half through-holes are respectively opened on the upper end and the lower end of the center shaft, balls are embedded in the half through-holes, the center shaft and the outer sleeve are connected on the middle lower end through threads, the lower sleeve, the spring and the upper sleeve are sleeved on the center shaft in turn, and the upper end button and the center shaft are connected on the lower end of the center shaft through threads, thirdly, a switching mechanism of an upper end apparatus is a switching mechanism of the actuator and mechanical arm of a robot in medical operations.

Description

(1) Technical field: [0001] The invention provides a fast switching device for the end of an actuator, in particular to a fast switching device for the end effector of the mechanical arm of a medical operation robot, which belongs to the technical field of continuous replacement of surgical instruments on the mechanical arm of a medical operation auxiliary robot. (two) background technology: [0002] Compared with doctors' manual operation, medical robots have great advantages in some aspects, because the positioning of the manipulator is much more accurate and powerful than that of humans, and the long-term operation may cause the surgeon's arm to tremble, and the manipulator will never appear in this way. situation. It is precisely because of the above-mentioned advantages of robots that surgical robots have been widely used in clinical practice. [0003] During the doctor's operation, as a robotic arm assisting the doctor's operation, it is necessary to switch the end ef...

AI Technical Summary

Problems solved by technology

In the existing robotic arm systems, many robotic arms are used to hold different surgical instruments. If it is necessary to replace different surgical instruments at any time for different operations during the same operation, the entire robotic arm has to be replaced. , will greatly increase the system cost

In addition, there are switching problems in some end effector switching devices of the same robotic arm, and it takes a certain amount of time to fix the instrument, which will greatly affect the doctor's operation time
