Description

Postoperative poking and suturing device for laparoscopic surgery

technical field

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

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.

It is very difficult to suture the poking hole after the existing laparoscopic surgery, especially in the case of a thick fat layer. Since the aperture does not exceed 12mm, it is difficult to suture to the peritoneal layer. Once the suture is not good, postoperative may Lead to the occurrence of poking hernia, which requires secondary surgical repair.
