[0002] In laparoscopic surgery and thoracoscopic surgery, laparoscopic cutting and stapler is usually used for cutting and anastomosis of esophagus, stomach, duodenum, small intestine, colon, rectum, appendix, gallbladder, pancreas and spleen in the digestive tract, and also for cutting and anastomosis of lung and trachea in the respiratory tract, and for cutting and anastomosis of bladder and uterus in the genitourinary system. Its application can greatly reduce surgical wounds, shorten operation time and improve operation quality.

[0003] In order to solve the above technical problems, a Chinese utility model patent application with publication number CN212592269U discloses a nail magazine with a high-strength nail pusher installation structure, including a nail magazine body. A knife groove and a receiving cavity for receiving the nail pusher are provided on the nail magazine body. The number of receiving cavities is set to 2, which are symmetrically distributed on the left and right sides of the knife groove. As for the right receiving cavity, a guide assembly for guiding the nail pusher is provided therein. The guide assembly includes a first guide member, a center guide member, a second guide member and a reinforcing arm, wherein the center guide member is extended upward from the bottom wall of the receiving cavity. The reinforcing arm is also extended upward from the bottom wall of the receiving cavity and is connected between the above center guide members. In this way, the above center guide members are interrelated and connected to form an organic force-bearing whole, thereby effectively preventing the center guide member from bending due to independent force, and ensuring that the center guide member is smoothly extended to perform tissue suturing operations.
