Circumcision stapler

Abstract

The invention discloses a prepuce loop line cutting and suturing instrument. The prepuce loop line cutting and suturing instrument comprises a knife pushing ring, a nail pushing ring, a nail bin and a nail board. A small knife is arranged on the knife pushing ring. The knife pushing ring rotates to drive the knife to conduct loop line cutting. The nail pushing ring is arranged above the nail bin. The nail board is arranged below the nail bin. The knife pushing ring is arranged in the nail pushing ring in a sleeved mode. A plurality of nail containing holes are formed in the nail bin and are arrayed in the inclined direction. Nail grooves corresponding to the nail containing holes in number and position are formed in the nail board. A push block is arranged on the nail pushing ring. The nail pushing ring rotates to drive the push block to push suturing nails in the nail containing holes to the nail grooves one by one. When the small knife is used for conducting prepuce rotating loop line cutting, the cutting resistance is small, the force used for cutting is even, and the stability is high; it is ensured that the suturing nails are arranged in a staggered mode due to the nail containing holes which are arrayed in the inclined mode, and the possibility that the nails are left in blood vessels during the operation is eliminated; nailing is conducted by sequentially pushing the suturing nails through the push block, and therefore stability is greatly improved, the nailing effect of the suturing nails is improved, the operation is simpler, and more labor is saved.

Description

technical field [0001] The invention relates to a medical device, in particular to 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 takes a long time. Although the existing cuttin...

Problems solved by technology

Although the existing cutting and stapler has the characteristics of smooth incision, short operation time, and easy operation, there are still certain defects: (1) adopt the concentric shaft push-cut suturing 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 suturing nails pierce the inner and outer plates of the foreskin at the same time, contact the top plate and bend them into shape. Piercing the tissue or the nails are not accurately formed, that is, they are not fully nailed, and 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; (2) Use staples arranged in parallel with the incisional edge of the foreskin , There is a gap between the nails, so that the probability of bleeding or hematoma is higher during and after the operation; (3) The circumcision is performed by concentric push-cutting, so that the circumcision cannot be seen during the operation. The structure of the glans penis and its frenulum cannot guarantee the safety of the frenulum from being cut, and the cutting length of the inner and outer plates of the foreskin cannot be precisely controlled; (4) the method of concentric shaft push-cut suture is not stable enough when the axial force is exerted, which is easy to cause Incomplete cutting and suturing during operation, and laborious
