Puncturing device for gastrointestinal laparoscopic surgery

Abstract

The invention relates to the technical field of abdominal puncturing devices, in particular to a puncturing device for a gastrointestinal laparoscopic surgery. The puncturing device comprises a hollowsupporting rack, a motor arranged inside a transverse plate of the hollow supporting rack is fixedly connected with a longitudinal screw rod through a speed reducer, a moving block is spirally connected to a screw rod body, limiting plates in the same direction with the screw rod are symmetrically and fixedly connected to the left and the right of the bottom face of the transverse plate, and provided with limiting grooves matched with limiting rods on the moving block, L-type movable plates are movably connected to the left end and the right end of a rectangular sleeve part fixedly connectedto the front side face of the moving block through an L-type connecting rod, arc-shaped clamping parts are connected to the bottoms of the L-type movable plates respectively and fixedly clamp a hollowcylinder with a puncturing needle, and a hollow cylinder body is communicated with a liquor collecting cavity through a guiding tube. The puncturing device is convenient to use and high in automationdegree when abdominal puncturing is conducted on a patient to draw out abdominal dropsy, and lowers the working difficulty of a medical worker.

Description

Technical field [0001] The invention relates to the technical field of abdominal cavity puncture devices, in particular to a puncture device for abdominal cavity surgery in gastrointestinal surgery. Background technique [0002] Abdominocentesis (abdominocentesis) is a diagnosis and treatment technique that uses a puncture needle to pierce the peritoneal cavity directly from the front wall of the abdomen. The exact name should be peritoneal puncture. Sometimes a proper amount of ascites needs to be drawn out to reduce the pressure in the patient's abdominal cavity, relieve symptoms such as abdominal distension, chest tightness, shortness of breath, and difficulty breathing, reduce venous return resistance, and improve blood circulation. Clinically, a puncture needle is used to aspirate ascites, and then the extracted ascites is dumped. In the past, doctors used manual operations for sampling, which was time-consuming and labor-intensive, increasing the work intensity of medical ...
