Suture cutting differential device of circumcision suturing device

Abstract

The invention discloses a suturing and cutting differential device of a prepuce loop line cutting and suturing instrument, and relates to a medical instrument. A base of the device and a nail pushing ring of the device are connected through threads. A push block is arranged at the lower end of the nail pushing ring. A knife pushing ring is arranged on the nail pushing ring. A small knife is arranged on the knife pushing ring. A gear body and the nail pushing ring are assembled together and connected with each other. The gear body abuts against the knife pushing ring. A support is arranged on the base and located above the gear body. The support limits rotation of the knife pushing ring through a clamping groove mechanism. The push block on the nail pushing ring rotates in the circumferential direction to push suturing nails in a nail bin below the push block one by one to conduct suturing, the knife push ring starts rotating and cutting the prepuce after overall descending to the clamping groove mechanism and being disengaged from the clamping groove mechanism due to the fact that the knife pushing ring is limited by the clamping groove mechanism, and therefore the aim of conducting cutting after suturing is achieved; nail pushing is completed through rotation, the operation process is simple, labor is saved, stability is increased due to the fact that suturing is conducted step by step, and the suturing effect is improved; it is ensured that prepuce is cut after nailing conducted through the suturing nails is completed due to the differential mechanism, and bleeding in the operation is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a suturing and cutting differential device on a disposable circumcision 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 ta...

AI Technical Summary

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

On the other hand, when the existing cutting and stapler cuts the foreskin, it adopts the method of cutting first and then suturing, which is easy to cause bleeding, redness and swelling during the operation.
