Surgery automatic purse-string stitching device

Abstract

The invention relates to an automatic surgical purse stitching instrument, which belongs to the technical field of medical apparatus and instruments. The surgical purse stitching instrument comprises an upper nail bin, a lower nail bin, an upper holder, a lower holder, a connecting rod of the holder and a handle. The nail bins are arranged in the holder. The holders, the connecting rod of the holder and the handle are molded into a whole. A cog is arranged on the stitching surface of the nail bin. The height of the cog is more than 1.2mm and equal or less than 1.7mm. When the upper nail bin and the lower nail bin are in involution, tissue clamped between the upper nail bin and the lower nail bin take on sawtooth waves. By adopting the stitching instrument to carry out the purse of the human tissue, the contact face between the nail bin and the human tissue can be effectively enlarged, the tissue is prevented from brimming over the instrument when the purse is being made and the shape of the purse is complete after the purse is made.

Description

technical field [0001] The invention relates to a surgical stapler, in particular to a surgical purse stapler, which belongs to the technical field of medical instruments. 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 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-string suture forceps to thread th...

Problems solved by technology

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-string suture forceps to thread the needle with thread The purse string suture is carried out by clipping the organized jaws. The disadvantage is that a needle needs to pass through a small hole in the jaws, which is inconvenient to operate.

The application of the automatic purse device solves the above problems, but in the process of use, it is found that the specification of the automatic purse device is limited after all, but the width of the tissue always changes, and in some special surgical locations, there is always Large-sized instruments cannot be put in, and small-sized instruments have some tissues on the outside of the instrument, which will affect the firing of the instrument and cause some purse-string nails to form poorly, which is not conducive to the promotion of clinical use.
