Nail Pushing Device of Circumcision Stapler

Abstract

The invention discloses a nail pushing device of a prepuce loop line cutting and suturing instrument, and relates to a medical instrument. The nail pushing device comprises a nail pushing ring, a nail bin and a nail board. The nail pushing ring is arranged above the nail bin. The nail board is arranged below the nail bin. A plurality of nail containing holes are formed in the nail bin and are arrayed in an inclined mode. Nail grooves corresponding to the nail containing holes in number and position are formed in the nail board. The nail pushing ring rotates to push suturing nails in the nail containing holes to the nail grooves. Due to the nail containing holes which are arrayed in the inclined mode, it is ensured that the suturing nails in the nail containing holes are arrayed in a staggered mode to form an annular shape, gaps between every two adjacent suturing nails are extremely small so that every two adjacent suturing nails can be almost closed, the possibility that the nails are left in blood vessels during the operation is eliminated, and the probability of bleeding and hematomas occurring during or after operations is greatly lowered.

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. Circumcision surgery is an effective method for the treatment of redundant prepuce and phimosis. [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...

AI Technical Summary

Problems solved by technology

The existing cutting and stapler uses staples arranged parallel to the foreskin, and there is a gap between the staples, so that the probability of bleeding or hematoma is higher during and after the operation

On the other hand, the cutting technology of the existing cutting and stapler adopts the concentric axis push-cut suturing method, that is, all the staples are pushed out of the staple cartridge at the same time and nailed into the tissue. This suturing method needs to strictly ensure that all the staples penetrate The inner and outer plates of the foreskin are in contact with the top plate and bent to shape. 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 nail to be not formed accurately, that is, not completely nailed. The forming force required for all the staples to pierce the tissue and form at the same time is also very large, which is not easy to operate
