Instrument transmission components, surgical instruments for surgical robots and surgical robots

Abstract

The invention provides an instrument transmission assembly, a surgical instrument of a surgical robot, and a surgical robot. The surgical instrument of the surgical robot includes a driving assembly; the instrument transmission assembly includes: an opening and closing instrument, a first pin shaft and a first transmission rod; an opening and closing instrument It includes a first body and a second body, the first body and the second body are intersected; the first pin is inserted at the intersection of the first body and the second body, the first pin is rotatably connected with the first body, and the first The pin shaft is fixedly connected with the second body; one end of the first transmission rod is connected with the first body through a transition rod, and the other end is connected with the driving assembly to drive the first body to rotate around the first pin shaft. When the opening and closing device grasps the article through the first body and the second body, since the second body does not rotate, the clamping of the opening and closing device is more stable, and the precise control of the opening and closing of the opening and closing device is further realized, thereby effectively increased the success rate of surgery.

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to an instrument transmission assembly, a surgical instrument for a surgical robot, and a surgical robot. Background technique [0002] At present, in related technologies, robot-assisted minimally invasive surgery has gradually become the development trend of minimally invasive surgery. During the operation, actions such as gripping, cutting, and support need to be completed, so the instrument transmission component must have the function of opening and closing. ; At the same time, surgical instruments work in the human body. When the surgical instruments are opened and closed in the human body, precise control of the surgical instruments must be achieved. If there is any deviation, it will affect the progress of the operation; , first of all, it is necessary to ensure that the clamped object does not fall, and second, it is necessary to ensure that the surgical instrument w...

[0002] At present, in related technologies, robot-assisted minimally invasive surgery has gradually become the development trend of minimally invasive surgery. During the operation, actions such as gripping, cutting, and support need to be completed, so the instrument transmission component must have the function of opening and closing. ; At the same time, surgical instruments work in the human body. When the surgical instruments are opened and closed in the human body, precise control of the surgical instruments must be achieved. If there is any deviation, it will affect the progress of the operation; First of all, it is necessary to ensure that the clamped object does not fall, and secondly, it is necessary to ensure that the surgical instrument will not affect other organs in the human body when it is opened and closed. Therefore, how to design a device that can be precisely controlled and can complete the opening and closing action, At the same time, it is necessary to grasp the surgical instruments of the stable surgical robot
