Abstract

The invention discloses a laparoscope postoperation trocar hole suturing device which comprises an outer sleeve, a push rod, four suturing needles and two suturing lines. The end, connected with a base, of the outer sleeve is provided with four longitudinal grooves. The base is provided with a groove. A needle holder is arranged in the groove. The needle holder is movably connected with the base through a pin shaft and a torsion spring. The needle holder is provided with a suturing needle installation hole. One end of the suturing needle is installed in the suturing needle installation hole, and the other end of the suturing needle is provided with a needle eye. A suturing line channel is arranged in the push rod. The bottom of the push rod is connected with the needle holder through a connecting rod. The two ends of the connecting rod are hinged to the outer sleeve and the needle holder through pin shafts respectively. The suturing device is further provided with a locking device used for fixing the push rod and a reset device. The laparoscope postoperation trocar hole suturing device is simple in structure, convenient to operate, and capable of safely, effectively and conveniently suturing a laparoscope operation wound.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a device for poking holes and suturing after laparoscopic surgery. Background technique [0002] Laparoscopic surgery has been widely used as one of the main treatment methods of minimally invasive surgery. Laparoscopic surgery is to open three to five small holes in the patient's abdomen, respectively insert the camera and surgical instruments into the abdominal cavity through the converter, and display the intra-abdominal images captured by the camera on the screen through the data cable. Using images on the screen, surgery is performed with surgical instruments inserted into the abdominal cavity. The development of laparoscopic surgery reduces the pain of surgery for patients and shortens the recovery period of patients. It is a surgical technique that has developed rapidly in recent years. [0003] It is very difficult to suture the poking hole after t...
