Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing clamp-type surgical instrument for minimally invasive surgery robot uses a motor to drive the wire wheel and then drive the steel wire to realize the rotation of the operation tube, wrist joint, left finger and right finger. When the wrist joint rotates, the left finger The excess movement of the left and right fingers cannot be compensated, resulting in the problem that the steel wires driving the left and right fingers are easily broken, and a clamp-type surgical instrument for a minimally invasive abdominal surgery robot is provided

Abstract

The invention discloses a clamp-type surgical instrument for an abdominal cavity minimally invasive surgery robot, relates to the clamp-type surgical instrument for the abdominal cavity minimally invasive surgery robot and aims to solve the problem of easy tensile failure of a steel wire which drives left fingers and right fingers due to failed compensation of residual movement of the left fingers and the right fingers during rotating of wrist joints because the steel wire is driven to rotate an operating pipe, the wrist joints, the left fingers and the right fingers by a motor driving wire wheel in the clamp-type surgical instrument for the conventional abdominal cavity minimally invasive surgery robot. The surgical instrument actuating mechanism is connected with an interface base and drives an operating pipe transmission mechanism, a left finger transmission mechanism, a right finger transmission mechanism and a wrist joint transmission mechanism on the surgical instrument actuating mechanism respectively through four driving mechanisms on the interface base; and the wrist joints, the left fingers and the right fingers on a tail end actuating mechanism are driven to move by a left finger front driving steel wire, a left finger back driving steel wire, a right finger front driving steel wire, a right finger back driving steel wire, a wrist joint front driving steel wire and a wrist joint back driving steel wire. The clamp-type surgical instrument is applied to abdominal cavity minimally invasive surgery.

Description

technical field [0001] The invention relates to a clamp-type surgical instrument for a minimally invasive abdominal surgery robot. Background technique [0002] Minimally invasive surgery refers to the operation performed on the human body through a minimum small incision. It is also generally called interventional surgery. Robot-assisted minimally invasive surgery uses various visual image equipment and advanced and dexterous surgical instruments to enter the human body through a small incision. The human body for treatment or diagnosis. The patent application number is 200910073301.6, the publication number is CN 101732093A, and the publication date is June 16, 2010. The invention patent application discloses a "clamp type surgical instrument for minimally invasive abdominal surgery robot", which is driven by a motor The wire wheel then drives the steel wire to realize the rotation of the operation tube, wrist joint, left finger and right finger. Although this patent incr...
