Novel gastrointestinal surgery abdominal cavity operation puncture device

Abstract

The invention discloses a novel gastrointestinal surgery abdominal cavity operation puncture device which comprises a puncture sleeve and a puncture needle body movably arranged in the puncture sleeve, a movable sealing ring is fixedly bonded to the circumference of the top end face of the puncture needle body, a puncture push rod is fixedly connected to the center of the top end face of the puncture needle body, and the movable sealing ring is fixedly connected to the bottom of the outer side of the puncture push rod in a sleeving mode. According to the novel gastrointestinal surgery abdominal cavity operation puncture device, after the puncture needle body is pulled out, the puncture sleeve is inserted into the abdominal cavity; gas in the abdominal cavity cannot leak to the outside fromthe puncture sleeve; pollution by external air is avoided, meanwhile, it is guaranteed that the internal air pressure of the abdominal cavity operation puncture device is stable, it is guaranteed that follow-up operations of doctors are stably conducted, the puncture needle body does not need to be directly pulled out of the abdominal cavity of a patient manually by doctors, and the trouble of pulling out the puncture needle body is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of gastrointestinal surgery, in particular to a novel puncture device for abdominal surgery in gastrointestinal surgery. Background technique [0002] Laparoscopic surgery is performed using laparoscopes and related instruments: use cold light sources to provide illumination, insert laparoscopic lenses into the abdominal cavity, and use digital camera technology to transmit images captured by laparoscopic lenses to post-stage signal processing through optical fibers. system and displayed on a dedicated monitor in real time. Then the doctor analyzes and judges the patient's condition through the images of different angles of the patient's organs displayed on the monitor screen, and uses special laparoscopic instruments for surgery. The puncture device is a commonly used medical instrument in laparoscopic surgery. During abdominal surgery in gastrointestinal surgery, the puncture device opens an operation hol...

Problems solved by technology

[0003] But, in the existing abdominal surgery puncture device at present, the puncture cannula is punctured in the abdominal cavity and after the puncture needle is set aside, the gas in the abdominal cavity will leak air from the puncture hole to the outside, so that the puncture hole can be opened after the puncture needle is pulled out. It is easy to leak air and be easily polluted by the outside air, which makes the internal air pressure of the trocar for abdominal surgery unstable, which is not conducive to the stable operation of the doctor's follow-up operation; and the puncture needle needs to be manually pulled out from the patient's abdominal cavity by the doctor, which also increases the big trouble
