Stitching head of surgery incising and stitching instrument

Abstract

The invention relates to a binding head of a surgical incision binding apparatus and belongs to the technical field of medical apparatus and instruments. The binding head comprises a nail anvil and a nail bin; the nail anvil is connected with a bracket; a nail molding slot is arranged at the side of the nail anvil; a suture nail is filled in the nail bin; the back of the nail bin is provided with a nail pushing plate, and the inner side is provided with a cutting knife. The binding head is characterized in that only one suture nail is arranged in the nail bin; a nail crown of the suture nail is provided with a plurality of nail legs; and the position of the nail molding slot on the nail anvil is corresponding to the position of the nail legs. The structure not only shortens the assembling process of instruments but also ensures that the nail is combined with the tissue more firmly after suture, and the phenomena of nail falling, tissue tear and the like do not occur.

Description

technical field [0001] The invention relates to a surgical cutting and binding instrument, in particular to a binding head of the surgical cutting and binding instrument, which belongs to the technical field of medical instruments. Background technique [0002] People have a history of more than 4,000 years in the understanding of hemorrhoids, and there have been endless theories about hemorrhoids for a long time. Since the 18th century, hemorrhoids were considered to be the abundant venous plexus in the lower rectum or anal canal. If they expand or varicose in one or several places, they become hemorrhoids. caused by vascular disease. Since the 1970s, breakthroughs have been made in the study of hemorrhoids, and the discoveries of anatomy, histology and physiology have given modern concepts to hemorrhoids. In 1975, Thomson proposed for the first time that "hemorrhoids are normal anatomical structures that everyone has. They are labial warts or anal cushions at the lower e...

Problems solved by technology

[0005] However, clinical application has found that in some patients, lesions do not occur in three hemorrhoids at the same time, but in one or two hemorrhoids. will be removed in one go

Obviously, this kind of operation will cause unnecessary damage to the patient and has no positive effect on postoperative recovery.

Moreover, the assembly process of existing surgical instruments is relatively cumbersome, and there are many surgical nails, and the phenomenon of missing nails often occurs

At the same time, due to the large number of suture staples used in surgery, each staple is controlled individually, and the forming effect of individual staples is often poor, which affects the surgical effect and is not conducive to the clinical application of this surgical method.
