Abstract

This invention discloses an abdominal paracentesis suture device, belonging to the technical field of abdominal paracentesis suture equipment. It includes a puncture needle, a syringe, a fluid collection tube, a suture angle adjustment device, a suture needle telescopic structure, and a fluid aspiration structure locking device. The puncture needle is inserted into the abdominal cavity, and the syringe is engaged with the puncture needle. The fluid collection tube is fixedly installed inside the syringe. The fluid aspiration structure locking device is engaged with the puncture needle and slides within the syringe. The suture angle adjustment device is engaged and concealed on the side wall of the syringe. The suture needle telescopic structure is engaged within the suture angle adjustment device. This invention addresses the current problems of complex operation and relatively fixed suture angles when switching between puncture and fluid aspiration modes. It provides an abdominal paracentesis suture device that effectively solves the problems of non-adjustable suture angles and inconvenient switching between puncture and fluid aspiration, improving operational flexibility and overall device integration.
