Problems solved by technology

Moreover, two or three independent instruments are actually used in the operation (two independent instruments if the outer cannula and puncture device are designed as one, or three independent instruments), which significantly increases the operation process and difficulty , which will prolong the operation time, increase the cost of the patient, and increase the risk of infection for the patient

Abstract

The invention belongs to the technical field of medical apparatuses and instruments and relates to a laparoscopic puncture stapler. The laparoscopic puncture stapler comprises a puncture awl component and a puncture sleeve component. The puncture sleeve component comprises a sleeve, a sleeve inner shell and a sleeve outer shell, the sleeve consists of a sleeve barrel and an outer tube, and two sides of the lower inner wall of the outer tube are provided with staples. Two sides of the sleeve inner shell are provided with clamping columns, and the sleeve inner shell and the sleeve outer shell are in butt joint to hold the sleeve and realize clamping connection through the clamping columns. The clamping columns on two sides are provided with coil springs, rotating wheels are arranged on the outer peripheries of the coil springs and wound by suture threads, and free ends of the suture threads are connected with the staples. The puncture awl component comprises a staple pushing mechanism and a staple pushing handle. Under the pressing action of the staple pushing handle, the staples penetrate human fascia tissues by the aid of the staple pushing structure. The laparoscopic puncture stapler has advantages that abdominal puncture under a laparoscope can be realized to create a passage for minimally invasive instruments to enter a body in laparoscopic surgery, and abdominal fascia suture can be quickly realized after the surgery.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, the invention relates to a laparoscopic puncture stapler. Background technique [0002] Laparoscopic surgery and thoracic laparoscopic surgery, as one of the main methods of minimally invasive surgery, have been widely used because of their small trauma and quick recovery. During the operation, it is necessary to perform pneumoperitoneum in the human abdominal cavity. Establishing pneumoperitoneum is an important operation process of the operation. When the pneumoperitoneum is sufficient, the distance between the abdominal cavity and the organs increases, which expands the surgical vision. Laparoscopic surgery needs to open a hole in the patient's abdomen, and the operation is performed under laparoscopic observation. After the operation, the fascia layer is often difficult to suture, resulting in the occurrence of hernia and affecting the patient's recovery. [00...
