Embodiment

[0028] Such as Figure 1-5 As shown, the embodiment of the present invention provides a puncture device for abdominal surgery in gastrointestinal surgery, which includes a base 1, and the tops of the base 1 are fixedly connected with support frames 11 on the sides away from each other. The support frames 11 are used to support the first threaded rod 12. At the same time, the existing The position of the second threaded rod 16 is provided with a through hole 42 in the center of the top of the base 1. The through hole 42 is the working position, which is convenient for the needle body 31 to enter the human body for puncturing tasks. The position chute, the limit chute acts to limit the working track of the limit cylinder 2, thereby improving the stability and accuracy of the device work, the two support frames 11 are respectively provided with the first threaded rod 12 on the side close to each other, and the two The first threaded rods 12 run through the support frame 11 respec...

Abstract

The invention provides a gastrointestinal surgery abdominal cavity operation puncture device, and relates to the field of medical equipment. The gastrointestinal surgery abdominal cavity operation puncture device comprises a base, the sides, away from each other, of the top of the base are fixedly connected with supporting frames respectively, a through hole is formed in the center of the top of the base in a penetrating mode, limiting sliding grooves are formed in the sides, close to the two supporting frames, of the top of the base respectively, and first threaded rods are arranged on the sides, close to each other, of the two supporting frames respectively; and the two first threaded rods penetrate through the supporting frames. After a puncture task is completed, a needle body is clamped by rotating a first grip and pushing two limiting cylinders to slide, a limiting gasket limits the needle body to prevent the needle body from sliding, and then a second grip is rotated to enable a second threaded rod to fix a limiting ring to prevent loosening caused by rotation of a first limiting rod. The use effect is good, and the problem that the needle body is shaken due to manual clamping in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a puncture device for abdominal surgery in gastrointestinal surgery. Background technique [0002] Paracentesis is a technique that directly penetrates the peritoneal cavity from the front wall of the abdomen with a needle or catheter to extract ascites, which is used to assist in the diagnosis and treatment of diseases. This technique is a simple method to determine whether there is ascites and to identify the nature of ascites. It is divided into diagnostic paracentesis and therapeutic paracentesis. [0003] When the applicant applied for the present invention, after searching, it was found that a Chinese patent disclosed a "peritoneal puncture device for gastrointestinal surgery" with the application number "202010567001.X", which included a support plate, a sleeve and a puncture rod; The middle position of the support plate is provided with an installation groove; ...
