Abstract

The invention provides a clamp type surgical instrument for a surgical robot. A support sleeve is connected with a bracket, and a wrist rotating shaft piece is mounted in the support sleeve. The wristjoint piece is connected with the wrist rotating shaft piece, and the wrist joint transmission rope is sleeved on the wrist rotating shaft piece. A left finger piece and a right finger piece are sleeved on the finger support shaft piece. A left finger transmission rope driving piece comprises a left finger driving input shaft sleeved with two left finger driving units, and the two left finger driving units are connected with a first left finger transmission rope and a second left finger transmission rope respectively. The right finger transmission rope driving piece comprises a right finger driving input shaft sleeved with two right finger driving blocks, and the two right finger driving blocks are connected with a rear-end of a first right finger transmission rope and a rear-end of a second right finger transmission rope respectively. The wrist transmission rope driving piece comprises: a wrist driving input shaft sleeved with two wrist driving blocks, and the two wrist driving blocks are connected with the wrist joint transmission rope. The instrument has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to the field of surgical robots, in particular to a clamp-type surgical instrument for a surgical robot. Background technique [0002] Chinese invention patent "Clamp-type Surgical Instrument for Minimally Invasive Abdominal Surgery Robot" application number: CN201110007611.5, discloses a clamp-type surgical instrument, in which, the left finger in the end effector needs to wrap around the finger installation axis to realize clockwise When turning, start the motor on the left-finger drive mechanism to make its output shaft rotate clockwise, and make the interface clutch disc rotate through the connecting piece, driving pulley, synchronous belt and passive pulley on the left-finger drive mechanism, and through the left-finger clutch The disk drives the left-finger arbor to rotate clockwise. At this time, the left-finger sun gear does not rotate, and the three left-finger planetary wheels mesh with the left gear teeth on the left-fi...
