Embodiment Construction

[0046] The technical scheme and features of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] Such as Figure 1 to Figure 17 As shown, the purse string stapler for surgery includes a shell 1 and a handle 8. There are two shells 1, and the middle part is pivotally connected by a pin 2 to form a movable structure similar to pliers. The handle 8 is positioned at the afterbody of the shell 1, and the head of each shell 1 is a suture head, and the upper and lower two suture heads cooperate with each other to play the role of sewing a purse. The inside of the suturing head is provided with a push plate 12 and a nail bin 3, and the inside of the nail bin 3 is provided with a nail pushing piece 4 and a nail forming guide groove. The nail 5 used for suturing the purse is located outside the nail pusher 4, placed inside the nail forming guide groove, with the nail feet facing outward, the positions of the upper and lower sut...

Abstract

A surgical purse-string suture device is composed of the shell with suture head and handle. The drive plate and pin cabin are in said suture head. The pin driving plate and pin shaping and guiding slot are in said pin cabin. The string bearing hole and the string fixer, through which the purse-string passes, are arranged at the lateral surface of suture head for putting the string between two pin feet. Its advantages are simple structure and short suture time.

Description

technical field [0001] The invention relates to a stapler used in surgical operations, in particular to a purse-string stapler for surgery, which belongs to the technical field of medical instruments. technical background [0002] Surgical purse-string suturing device is a medical device often used in surgical operations on intestinal and other physiological tissues. The performance of the instrument directly affects the operation process and plays a very important role in the operation effect. In the prior art, when using a stapler for suturing, purse-string sutures must be performed on the stump of the organ, so that it can be firmly ligated after the central rod is inserted, and then the stapler can be implemented. There are two methods for performing purse-string suture surgery: one is manual suture, which is not only time-consuming and labor-intensive, but also the depth of the needle is different, and the stitch distance is inconsistent; the other is to use purse-strin...
