Abstract

The invention discloses a surgical instrument for a minimally invasive surgical robot and a minimally invasive surgical robot; the surgical instrument includes a front end driving part, a guide rod part, and an end effector part connected in sequence, and the end effector part includes a wrist part connected in sequence. external devices and end effectors. The front end drive section includes a yaw drive. The front-end driving part also includes an opening and closing driving device and a rotating driving device. Wherein, the deflection driving device is used to drive the deflection angle of the wrist device, and the opening and closing driving device is used to drive the opening and closing degree of the end effector. The wrist device of the minimally invasive surgical robot can realize the deflection of unilateral degree of freedom, which can drive the deflection of the end effector without affecting the opening and closing of the end effector, thus greatly increasing the flexibility of robotic surgery. flexibility.

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.
