Instrument assembly, surgical instrument of surgical robot and surgical robot

Abstract

The invention provides an instrument assembly, a surgical instrument of a surgical robot and the surgical robot. The instrument assembly comprises a connecting shaft and a driving rod, wherein one end of the connecting shaft is connected with a drive component, and a first gear is arranged on the connecting shaft; the driving rod is provided with a second gear, and an operation executing part is arranged at one end of the driving rod; the first gear is meshed with the second gear, the drive component drives the connecting shaft to rotate, the connecting shaft drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the driving rod to rotate to drive the operation executing part to rotate. By means of the instrument assembly, the rotation control over the operation executing part is achieved so that the operation executing part can reliably rotate within a limited space; meanwhile, since the instrument assembly is adopted in the surgical instrument of the surgical robot, a control instruction sent by a doctor can be quickly, accurately and reliably executed to control the movement of the operation executing part, and thus normal run of an operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to an instrument assembly, a surgical instrument for a surgical robot, and a surgical robot. Background technique [0002] At present, robot-assisted minimally invasive surgery has gradually become the development trend of minimally invasive surgery. The surgical instruments of surgical robots have complex structures and large volumes, which further compress the robot's activity space. Therefore, how to design a surgical robot that can be assembled and moved flexibly in a limited space has become an urgent problem to be solved. Contents of the invention [0003] In order to solve at least one of the above technical problems, an embodiment of the first aspect of the present invention provides an instrument assembly. [0004] The embodiment of the second aspect of the present invention also proposes a surgical instrument for a surgical robot. [0005] In the embodiment of ...

AI Technical Summary

Problems solved by technology

[0002]At present, robot-assisted minimally invasive surgery has gradually become the development trend of minimally invasive surgery. In related technologies, due to the characteristics of minimally invasive surgery, the activities of robots The space is greatly restricted, resulting in the inability of the robot to move freely, and due to the complex structure and large size of the surgical instruments of the surgical robot, the activity space of the robot is further compressed
