Nail-pushing device for circumcision and stapler

Abstract

The invention discloses a nail pushing device of a prepuce loop cutting suturing device, and relates to medical apparatuses and instruments. The nail pushing device comprises a base, a nail pushing ring, a nail bin and a nail plate. The base is in threaded connection with the nail pushing ring, the nail bin is provided with an annular groove and a plurality of nail storage holes, the annular groove is formed in the position close to an inner circumference, and the lower end of the annular groove is connected to the nail storage holes arranged in a circular mode. Nail pushing blocks are arranged inside the nail storage holes, and are matched with the nail storage holes in shape. The nail pushing ring is arranged above the nail bin, and the nail pushing ring is provided with a protruding block corresponding to the annular groove in position. The nail plate is arranged below the nail bin, and the nail plate is provided with nail grooves which correspond to the nail storage holes in number and position. According to the nail pushing device of the prepuce loop cutting suturing device, nail pushing work is completed through rotating operation, stability is increased greatly through the mode that the protruding block pushes out suturing nails one by one, the nailing effect of the suturing nails is improved, and the nail pushing device of the prepuce loop cutting suturing device is simple and saves labor.

Description

technical field [0001] The invention relates to a medical device, in particular to a nail pushing device used on a disposable circumcision stapler. Background technique [0002] Prepuce or phimosis is a common reproductive problem in men. With the continuous improvement of people's living standards and health awareness, higher requirements are placed on their own reproductive health. Excessive prepuce is easy to hide dirt, leading to glans foreskin inflammation, affecting normal married life, and increasing the chance of sexual partners suffering from cervicitis and cervical cancer.

[0003] At present, excessive prepuce usually adopts the method of conventional circumcision and cutting and stapler. Conventional circumcision uses manual cutting and suturing, which makes the foreskin incision uneven, causes more bleeding during the operation, and takes a long time. Although th...

Problems solved by technology

The cutting technology of the existing cutting and stapler adopts the concentric shaft push-cut suture method, that is, all the staples are simultaneously pushed out of the staple cartridge and nailed into the tissue. This suture method needs to strictly ensure that all the staples pierce the inner and outer plates of the foreskin at the same time. The top plate is bent and shaped, and the structure of the concentric shaft pushing the top often has problems such as offset, skew, and uneven push, which is very easy to cause the tissue not to be completely pierced or the nails to be accurately formed, that is, not completely nailed, and all the staples The forming force required to pierce the tissue and form it at the same time is also very large, and it is not easy to operate
