A suturing and cutting differential device of a circumcision suturing device

Abstract

The invention discloses a suture and cutting differential gear of a prepuce loop cutting suturing device, and relates to medical apparatuses and instruments. A pushing block is arranged at the lower end of a nail pushing ring, a cutter pushing ring is arranged on the nail pushing ring, a small cutter is arranged on the cutter pushing ring, a gear body and the nail pushing ring are connected in a mutual matched mode, the gear body butts against the cutter pushing ring, a support is arranged on a base and is located above the gear body, and the support restrains the rotation of the cutter pushing ring through a clamping groove mechanism. According to the suture and cutting differential gear of the prepuce loop cutting suturing device, the pushing block on the nail pushing ring rotates in the peripheral direction to push suturing nails in a lower nail bin out to carry out suture, due to the limitation demand of the clamping groove mechanism, the cutter pushing ring needs to go down integrally to the clamping groove mechanism and be separated, and then starts to rotate to cut prepuce, the operation of suture first and cutting second is achieved, nail pushing is completed through rotation, operation is simple, labor is saved, stability is increased by nailing one by one, and the nailing effect is improved. The suture and cutting differential gear guarantees the fact that prepuce cutting is carried out after complete suturing nail nailing is carried out first, and bleeding in an 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.
