Abstract

The invention discloses a surgical instrument for a minimally invasive surgical robot and a minimally invasive surgical robot. The surgical instrument comprises a front-end driving portion, a guide rod portion and a tail-end execution portion in sequential connection. The tail-end execution portion comprises a wrist device and a tail-end execution device in sequential connection. The front-end driving portion comprises a deflection driving device, an opening-closing driving device and a rotation driving device. The deflection driving device is used for driving a deflection angle of the wrist device, and the opening-closing driving device is used for driving openness of the tail-end execution device. By the wrist device of the minimally invasive surgical robot, deflection of degrees of freedom of two sides can be realized so as to drive the tail-end execution device to defect without affecting openness of the tail-end execution device, and accordingly surgical operation flexibility of the robot is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical instrument for a minimally invasive surgical robot and a minimally invasive surgical robot. Background technique [0002] In minimally invasive surgery, doctors often need to manually cut, strip, and suture tissues. For some complicated surgical operations, doctors need to stand for a long time and hold micro-surgical instruments for surgery. Doctors are prone to fatigue, which affects the operation. quality. At the same time, conventional minimally invasive surgical instruments are simple imitations of traditional open surgical instruments, with less freedom, low flexibility, and high internal friction, which will lead to attenuation of transmission force and fatigue of doctors, making it difficult to avoid hand tremors, The reduction of the accuracy of the operation caused by fatigue is not convenient for the smooth operation of the operation.
