Description

Quick stitching instrument for endoscopic surgery Technical Field The invention relates to the technical field of medical instruments, in particular to a rapid suture device for endoscopic surgery. Background Minimally invasive endoscopic surgical procedures avoid open wound surgery and support closed or partial surgical procedures with less trauma. Minimally invasive surgery typically involves remote manipulation of instruments that can be indirectly viewed through an endoscope or similar device to the surgical field and either through a small portal through the skin, or through a body cavity or anatomical opening. Minimally invasive endoscopic medical techniques thereby reduce tissue damage during diagnostic procedures or surgical procedures, thereby reducing patient recovery time, discomfort, and adverse side effects. Minimally invasive medical techniques therefore reduce the average length of time during which the procedure is hospitalized compared to standard open surgery. One form of minimally invasive surgery is endoscopic surgery. The most common form of endoscopic surgery is probably laparoscopic surgery, which is a minimally invasive examination and operation within the abdominal cavity. In standard laparoscopic surgery, gas is blown into the patient's abdomen and a cannula is passed through a small (approximately 1/2 inch) incision to provide access to laparoscopic surgical instruments. Laparoscopic surgical instruments typically include an endoscope for viewing the surgical field and, in some embodiments, a specialized surgical instrument that passes through the portal. Such instruments may include, for example, clamps, graspers, scissors, staplers, and needle holders. These surgical instruments may or may not be similar to those used in conventional (open) surgery, typically the working end of each instrument is spaced from its handle by an elongate shaft and sized and configured to fit through an access port. To perform surgery, surgeons pass surgical instruments through portals to surgical sites in the body and manipulate the surgical instruments from outside the abdominal cavity. The surgeon monitors the procedure with a monitor that displays images of the surgical site taken from the laparoscope. However, after the back joint operation of the minimally invasive surgery endoscopic surgery is finished, the wound is sutured by fixing suture lines, when the back joint operation is finished, the distance between the back joint and the soft tissue is small by a common operation tool, the distance between the back joint and the soft tissue is small, the common operation tool is long, and the operation suture can not be performed between the back joint and the soft tissue, so that the operation suture process needs to be repeatedly performed, the line is gripped, and the operation time is prolonged. Disclosure of Invention The invention aims to solve the technical problems that the distance between the rear joint and the soft tissue is smaller and the surgical suture can not be performed, so that the surgical suture process needs repeated threading, thread grasping and operation time extension, aim at provides a quick stapler of laparoscopic surgery, can realize the quick sewing of operation in the less distance between back joint and the soft tissue, improves stapler's availability factor. The invention is realized by the following technical scheme: A endoscopic surgical rapid stapler comprising: A stapler body; the connecting rod body is connected with the stitching instrument body at one end; the wire stroking column is respectively arranged in the stitching instrument body and the connecting rod body, one end of the wire pulling device is used for pulling the push-pull device capable of moving axially, the push-pull device is matched with the autorotation threading device, the other end of the wire pulling device penetrates through the gear piece and is connected with the rotating roller through the outer circumferential surface of the wire stroking column, and the gear piece is fixed in the connecting rod body; The suture rod body is connected with the other end of the connecting rod body at one end, and a push-pull device and the threading device are arranged in the other end of the suture rod body; an elastic piece is arranged between the push-pull device and the gear piece, and the pull wire passes through the elastic piece and the gear piece from the push-pull device to the turning roll. The wire stroking post is fixed in the stitching instrument body and the inside of the connecting rod body, the gear piece is a stop block, the stop block is provided with a through hole, and the stay wire passes through the elastic piece and the through hole from the push-pull device to reach the rotating roller. The elastic piece is any one of a spring or a hollow rubber column. The left end and the right end of the elastic piece are respectively abutted against the end surfaces of the push-pull device a
