Abstract

The invention relates to a puncture stapler capable of arranging sutures in advance, and relates to the technical field of medical instruments. The puncture stapler capable of arranging sutures in advance comprises a puncture cannula device and a puncture device. The puncture cannula device comprises a shell cover, a connecting base, a cannula upper shell, a cannula lower shell, a sealing gasket upper pressing piece, a sealing gasket, a sealing gasket lower pressing piece, a rubber ring, a choke valve, a cannula, an air injection valve and a snap clip. The puncture device comprises a handle, a puncture shell cover, a baffle plate, a side wing locking block, a spring, a baffle block, a puncture tube, a push-pull rod, a guide connecting block, a side wing, a puncture cone, a wire pushing rod, a long pressure spring, a baffle ring, a fixed shaft, a puncture shell and a connecting pin. The puncture stapler can be used for laparoscopic abdominocentesis, and establishing channels for laparoscopy. According to the puncture stapler, a pre-knotting mode of sutures is provided, the sutures on the two sides of an incision can be pulled out of the cannula to be pre-knotted without affecting intraoperative procedures.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, the invention relates to a puncture stapler capable of pre-arranging sutures. Background technique [0002] Laparoscopic surgery has gradually replaced traditional surgery due to its advantages of less trauma, less interference to patients' physiology, better cosmetic effect, less pain, and faster recovery. It has been widely used in general surgery, gynecology, and cardiothoracic surgery. Laparoscopic surgery needs to open a hole in the patient's abdomen, and the operation is performed under laparoscopy. After the operation, fascia suture is required. Because of the characteristics of small incision and deep inner wall, the suture operation is difficult. The current solutions include manual suturing and fascial stapler suturing. Manual suturing is suitable for thin patients. For obese patients, the abdominal wall tissue is thick, which cannot meet the precise and e...
