The staple cartridge assembly includes a staple cartridge 4, and nail pushers 5 and nails 6 placed in the staple cartridge 4. The staple cartridge assembly of the present invention is the same as the prior art, except that in the initial state, one end of the upper shell 1 and the lower shell 2 is pivotally connected and arranged at an acute angle. After the shell 2 is rotated and made to be substantially parallel to each other, the upper shell 1 and the lower shell 2 can move relative to each other so that the nail pushing piece 5 pushes the nail 6 out of the nail bin 4 . Compared with the prior art, the shell of the present invention is much smaller, convenient to manufacture and saves a lot of raw materials.

Abstract

The invention provides an automatic purse-string device, which comprises an upper shell and a lower shell, and nail warehouse components arranged inside of the shells, wherein the nail warehouse components comprise a nail warehouse, a nail pushing piece and a nail arranged in the nail warehouse. When in an initial state, one end of the upper shell and one end of the lower shell are in pivot connection and are arranged in an angle; and when in the process of working, the upper shell rotates relative to the lower shell, and the upper shell and the lower shell move relative to make the nail pushing piece push the nail out of the nail warehouse after the upper shell is parallel to the lower shell. The automatic purse-string device has the main advantages that the device is compact in appearance, can be packaged and sold serving as an attachment of other surgical instruments, saves material cost, can reduce the economic burden of a patient, and can satisfy the use in a smaller surgical space, thereby enlarging use range and providing a doctor with convenience.

Description

technical field [0001] The invention relates to a purse-string suturing device, in particular to an automatic purse-string suturing device, which belongs to the field of medical devices. Background technique [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 of 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 needle pitch is inconsistent; the other is to use purse-string suture forceps t...
