Laparoscopic suturing device

Abstract

The invention relates to a laparoscopic suturing device. The device comprises a handle, a swinging head and a gun sleeve, the upper end of the handle is hinged to a wrench, the swinging head is provided with a swinging head seat, the front end of the swinging head seat is provided with an arc-shaped track for placing sewing needles, the rear end of the swinging head seat is rotationally provided with a turntable, the turntable is eccentrically hinged to a swing rod for driving the sewing needles to rotate, the turntable is coaxially provided with a rotary sheave, and the handle is internally provided with a first traction steel wire of which the front end penetrates through the gun sleeve and is in winding connection with the rotary sheave along one side of the rotary sheave, and a secondtraction steel wire of which the front end penetrates through the gun sleeve and is in winding connection with the rotary sheave along the other side of the rotary sheave. According to the invention,the first traction steel wire and the second traction steel wire pull the rotary sheave to alternately rotate clockwise and anticlockwise, and the turntable drives the swing rod to drive the rotary motion of the sewing needles, so that the precise position of the rotary motion of the sewing needles is ensured, and the success rate of the operation is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic stapler. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, which is mainly used for intra-abdominal examination and treatment. When suturing the postoperative human tissue during the operation, the doctor fires it through the wrench on the handle of the stapler, continuously pulls and loosens the wire rope, and drives the front end to swing the head to drive the suture needle to continuously rotate, pierce the human tissue and suture. [0003] The existing structure of the stapler usually pulls the rack by a single wire rope to drive the swing head to rotate, relying on the spring back to reset the swing head, so as to continuously circulate, the structure is more complicated, and the suture needle is prone to not turning in place during the operation This phenomenon makes it difficult to control the mov...

AI Technical Summary

Problems solved by technology

[0003] In the existing structure of the suture device, the rack is usually pulled by a single steel wire rope to drive the swing head to rotate, and the swing head is reset by the elastic force of the spring, so as to continuously circulate, and the structure is relatively complicated. This phenomenon makes it difficult to control the movement of the wrench during suturing, which increases the difficulty of the operation; at the same time, because a single wire rope is used to pull it, it is necessary to tighten the wrench after the suture needle is in place to adjust the position of the suture needle, and the force generated will affect the suture. Negative effect on needles, poor operational reliability
