Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] according to figure 2 As shown, the surgical stapler of the present invention includes a housing 1, a central rod 2, an annular push tube 3 and a push plate. The casing 1 is provided with a stroke indicating window 11, and an activation handle 7 is installed on the outer surface of the casing 1. The activation handle 7 is movably connected with the casing 1 through a hinge, and can rotate around the hinge axis. The annular push tube 3 is arranged in the casing 1, and the center rod 2 is sheathed in the casing. The annular push tube 3 front ends are fixed together with the bottom surface of the push plate, and the top of the push plate is provided with an anvil on which staples are housed. The central rod 2 extends out of the housing, and the front end of the central rod 2 is fixed with a nail cover 4 , while the rear end is conn...

Description

technical field [0001] The invention relates to a surgical stapler. Background technique [0002] As a common tool in surgical operations, staplers are widely used to anastomose human tissues during surgery, such as the esophagus, duodenum, small intestine, colon, and rectum of the digestive tract. They are suitable for the ends of various tubular organ tissues. End-to-end, end-to-side and side-to-side anastomosis. The stapler can reduce the suturing time of tubular tissues, increase the suture strength, reduce the difficulty of surgery, effectively protect the sutures of tubular organ tissues, improve the quality of surgery, and greatly improve the healing effect of sutures. [0003] Existing medical and surgical staplers, such as figure 1 As shown, it generally includes a housing 1, a center rod 2, a push tube 3 and a push plate, and an indicating window 11 is opened on the housing 1. Push tube 3 heads are fixed together with the bottom surface of the push plate, and th...
