Puncture device for abdominal cavity operation in gastrointestinal surgery

Abstract

The invention belongs to the technical field of medical equipment, and specifically relates to a puncture device for abdominal cavity operation in gastrointestinal surgery. The device comprises a support plate, a sleeve, and a puncture rod; a mounting groove is arranged in the middle of the support plate; adjustment rotor blocks are evenly arranged inside the mounting groove; the same sleeve is inthreaded connection among the adjustment rotor blocks together; a stepped mounting hole is arranged inside thee sleeve; a rotating block is fixed connected to the inside of the stepped mounting hole;an adjustment hole is arranged inside the rotating block; and the same puncture rod is inserted between the stepped mounting hole and the adjustment hole. According to the present invention, the support-type abdominal puncture operation is effectively realized by the device, the problems that in the direct puncture process, doctors need to sense whether is in place through the sense of vacuum failure, and the puncture technique difficulty and the operation risk are high, are solved, slow puncture operation is realized through a progressive spiral structure, the structure is simple, and the risk of puncture is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a puncture device for abdominal surgery in gastrointestinal surgery. Background technique [0002] The trocar is a surgical instrument that cooperates with minimally invasive equipment to provide instrument channels for minimally invasive abdominal and pelvic surgery. In minimally invasive human medical surgery, once a disease is found in the human body, surgery or resection is required. During the operation, the first thing to be used is A trocar, a trocar is a surgical instrument that pierces the abdominal wall and enters the body cavity channel for other surgical instruments, and belongs to a minimally invasive surgical instrument. The puncture rod in the sleeve assembly, firstly, in order to penetrate the skin, cut the skin epidermis with a scalpel, then use the puncture rod to penetrate the skin and enter the body cavity together with the sleeve assembly, then pull...

Problems solved by technology

[0003] According to CN108784794A, a new type of puncture device for abdominal surgery in gastrointestinal surgery, in the prior art, when performing abdominal puncture, the doctor holds a sleeve with a puncture rod in his hand and inserts it into the abdomen towards the abdomen where the epidermis is cut. Rotate the sleeve while turning the sleeve. When there is a sense of vacuum falling, it indicates that the sleeve has reached the peritoneal layer. At this time, the doctor needs to stop immediately and continue to insert into the patient’s abdominal cavity to avoid the problem of the puncture rod or sleeve being inserted too deep and hurting internal organs, but the vacuum falls. It is only the feeling of operation after penetrating into the covering layer, and it is difficult for doctors who are operating for the first time to control it, so the difficulty and risk of paracentesis increase.
