Problems solved by technology

When the front end of the actuator is subjected to a large force, coupled with the amplified effect of the leverage of the actuator on the joint, the angle at which the actuator rotates to both sides will be changed, and the positioning accuracy is poor.

Abstract

The invention discloses a joint control mechanism of an endoscopic surgical instrument. The joint control mechanism of the endoscopic surgical instrument has the technical characteristic that a jointcontrol case, a joint driving wheel, a joint knob and a joint driving rod are arranged in the joint control mechanism. The joint control mechanism of the endoscopic surgical instrument has the technical scheme that the joint knob drives the joint driving wheel to rotate through a gear transmission mechanism; the joint driving wheel drives the joint driving rod to forwards and backwards move through a spiral transmission mechanism; the joint driving rod drives a joint assembly to do joint rotation; and an execution assembly swings along with the joint rotation of the joint assembly. The spiraltransmission mechanism has a self-locking effect and can resist the lever force amplification effect of the execution assembly on the joint assembly, so that the technical effect of positioning the execution assembly in a proper position is achieved. Through the cooperation of a bevel gear transmission mechanism and a spiral transmission mechanism, a stepless adjustment effect is achieved; and technical effect that the execution assembly does joint rotation towards two sides to a proper angle through stepless adjustment is achieved.

Description

technical field [0001] The present invention relates to an endoscopic surgical instrument used in surgical operations, in particular to an endoscopic surgical instrument used in laparoscopic surgery, and in particular to an endoscopic surgical instrument used in thoracoscopic surgery. Background technique [0002] In laparoscopic surgery and thoracoscopic surgery, various manual or motorized endoscopic surgical instruments are usually used for clamping, cutting, injecting, cutting, suturing and anastomosis in the abdominal cavity, thoracic cavity and genitourinary system Surgery can reduce surgical trauma, shorten operation time, and improve operation quality.
