Problems solved by technology

[0004] The long tube of the existing puncture device is fixed on the human body or animal during the operation stage. Due to its long length, it is easy to be touched and shaken, which easily interferes with the operation of medical personnel.
In addition, since the knife is only limited by the wall of the long tube, the long tube and the instrument will still move relative to each other. If the positioning position is shifted, when the position needs to be adjusted, it may cause additional destructive invasion, causing the wound to expand, resulting in Patient Pain and Discomfort

Abstract

A puncture outfit comprises a puncture instrument and a sleeve joint part. The puncture instrument comprises a base and a puncture portion, the puncture portion comprises a bump and a tip, and the bump radially extends outwards from the outer surface of the puncture portion. The sleeve joint part comprises an air pressure seat, a first sleeve component, a second sleeve component, a fixed seat andan airbag. The second sleeve component can shrink, so that the first sleeve component is placed in the second sleeve component. The fixed seat is fixed to the second sleeve component, the inner wall of the fixed seat is provided with a guide groove and a key groove, the depth of the guide groove is larger than that of the key groove, and the guide groove is communicated with the key groove. When the bump of the puncture instrument enters the guide groove, after the bump is clamped in the key groove by rotation, the puncture instrument is fixed to the fixed seat and drives the fixed seat to move along the direction of the long axis of the puncture instrument.

Description

technical field [0001] The invention relates to a minimally invasive surgical tool, in particular to a trocar. Background technique [0002] Today's surgical operations use a trocar (Trocar) instead of a scalpel to open an opening in the human body, and then use optical fibers, endoscopes, lasers and other medical instruments to perform surgical procedures such as tissue burning and excision in the body. This surgical method can reduce wounds, reduce pain, shorten bed rest and postoperative rest time, and reduce scars after recovery. These surgeries are called minimally invasive surgeries because of the small wounds and quick recovery. [0003] The puncture device usually includes a long tube and a knife for puncturing. The knife is inserted into the long tube. After the knife is opened from the human body or animal, it can be withdrawn from the long tube, and the long tube is fixed on the human body. Then, The relevant surgical tools such as optical fiber, endoscope, lase...
