Abstract

The invention discloses a surgical instrument for a minimally invasive surgery robot and the minimally invasive surgery robot. The surgical instrument comprises a front end driving part, a guide rod part and a tail end execution part which are connected in sequence, and the tail end execution part comprises a wrist device and a tail end execution device which are connected in sequence. The front end driving part comprises a deflection driving device. The front end driving part further comprises an opening-closing driving device and a rotating driving device. The deflection driving device is used for driving the deflection angle of the wrist device, and the opening-closing driving device is used for diving the opening degree of the tail end execution device. According to the surgical instrument, the wrist device of the minimally invasive surgery robot can achieve the deflection of the freedom degree of a single side, the deflection can drive the deflection of the tail end execution device, but the opening degree of the tail end execution device is not influenced, and accordingly the flexibility of the surgical operation of the robot is greatly 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.
