Puncture device for abdominal operation in gastrointestinal surgery

Abstract

The invention discloses a puncture device for an abdominal operation in a gastrointestinal surgery, and particularly relates to the field of abdominal puncture devices. The device comprises a supportframe, wherein the top of the support frame is fixedly connected with a first electric push rod, the top of the first electric push rod is fixedly connected with a connecting block, a needle handle isarranged at the bottom of the connecting block, a movable through groove is formed in the support frame, the inner wall of the movable through groove is movably connected with a protecting tube, theinner wall of the protecting tube is fixedly connected with a limiting tube, the inner wall of the limiting tube is movably connected with the surface of the needle handle, the bottom of the needle handle is fixedly connected with a puncture needle, the top of the protecting tube is in threaded connection with a sealing cover, and the middle part of the sealing cover is fixedly connected with an alcohol pad. The puncture needle is always positioned in the protecting tube when not in use. When in use, the puncture needle penetrates through the alcohol pad so as to be sterilized and then is directly penetrated into the body of a patient to avoid contact with the outside air, thereby achieving the purpose of safe puncture.

Description

technical field [0001] The present invention relates to the technical field of abdominal cavity puncture device, more specifically, the present invention relates to a puncture device for abdominal cavity operation of gastrointestinal surgery. Background technique [0002] Paracentesis, also known as peritoneal cavity puncture, is a diagnosis and treatment technique that directly penetrates the peritoneal cavity from the anterior abdominal wall with the help of a puncture needle. Mid-paracentesis is also used to relieve dyspnea caused by large amounts of ascites. Paracentesis involves two main processes of puncture and drainage. Therefore, it is necessary to use a special puncture needle clinically. Unlike conventional injection needles, the puncture needle is generally long and relatively large in diameter, so the operation during the puncture process should be extremely cautious. [0003] The patent application publication number CN201910010494.4 discloses a puncture devi...
