Problems solved by technology

[0002] Laparoscopic surgery and thoracoscopic surgery, as one of the main methods of minimally invasive treatment, have been widely used because of their small trauma and quick recovery. Laparoscopic surgery needs to open a hole in the patient's abdomen and perform surgery under laparoscopic observation. In the end, it is often difficult to suture the fascia layer, resulting in the occurrence of a hernia and affecting the recovery of the patient.
In addition, in the current abdominal and thoracic surgery, the puncture device is usually pulled out after the puncture operation, and then the suture device is inserted into the abdominal cavity for suturing, which is cumbersome and increases the pain of the patient.

Abstract

The invention belongs to the field of medical apparatuses, and particularly relates to an endoscope puncture and suturing instrument. The endoscope puncture and suturing instrument comprises an outersleeve, a puncture device and a suturing device, wherein the puncture device is provided with a handle, a push rod and a detachable puncture head in sequence, and the suturing device comprises two suturing thread pushing rods and a suturing thread; the outer sleeve is coaxial to the push rod, the ends of the suturing thread pushing rods are both provided with a metal plug, and the two ends of thesuturing thread are fixed into the two metal plugs respectively; a magnetic device is further arranged on the puncture device, and a connector connected with the push rod is formed in the magnetic device. According to the endoscope puncture and suturing instrument, puncture and operations of the abdominal cavity can be achieved with the assistance of an endoscope, and the fascia of the abdominal cavity can be sutured after the operations; the whole endoscope puncture and suturing instrument is simple in structure and convenient to operate, and can simply suture the fascia and reduce the occurrence of operative complications.

technical field [0001] The invention belongs to the field of medical instruments, in particular to a laparoscopic puncture stapler. Background technique [0002] Laparoscopic surgery and thoracoscopic surgery, as one of the main methods of minimally invasive treatment, have been widely used because of their small trauma and quick recovery. Laparoscopic surgery needs to open a hole in the patient's abdomen and perform surgery under laparoscopic observation. In the end, it is often difficult to suture the fascia layer, resulting in the occurrence of a hernia and affecting the recovery of the patient. In addition, in the current abdominal cavity and thoracic cavity surgery, the puncture device is usually pulled out after the puncture operation, and then the suture device is inserted into the abdominal cavity for suturing, which is cumbersome and increases the pain of the patient. [0003] Currently on the market, one end of the puncture and suture integrated instrument is fixe...
