Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and relates to a circumcision stapler (abbreviated as: foreskin stapler), which is suitable for being used as an anastomotic surgical instrument for male circumcision due to excessive foreskin or phimosis, and in particular to a circumcision anastomosis component, which contains a glans seat structure of the foreskin stapler. Background Art

[0002] As people's living standards continue to improve, they have higher requirements for their own health and quality of life. Prepuce is a common reproductive problem in men. Many men suffer from prepuce inflammation, penis development, and penis inflammation due to prepuce or phimosis. Circumcision is an effective method for treating phimosis and prepuce. Traditional circumcision generally uses direct cutting and suturing methods, which takes a long time to operate, causes great damage to tissues, takes a long time to recover, and leaves obvious scars after surgery. The operation process has many steps, including anesthesia, cutting, hemostasis, suturing, etc., which requires the cooperation of multiple people. Each case takes 25 to 40 minutes, and requires high skills and experience of the operator.

[0003] The disposable circumcision suture device surgical method adopts the method of installing the glans base suture device during the operation, activating the blade to cut the foreskin, and suturing the nails to complete the suturing. It has been widely used in clinical practice and has been widely recognized at home and abroad. The existing circumcision ring type circumcision stapler (circumcision cutter) is difficult to grasp and control the force of circumcision according to the individual conditions of the patient during the operation, and the probability of one-time success is relatively low; after circumcision, the doctor needs to suture the wound, resulting in a lengthy operation process and increased pain for the patient. There are also automatic circumcision suture devices, but the suture device is used in conjunction with the circumcision cutter. Circumcision surgery and surgery with the help of small instruments require high clinical experience of doctors, and the operation is cumbersome. If you are not careful, it will cause excessive bleeding. After the circumcision cutter cuts the foreskin, the suture device is used to suture, which will increase the number of surgical instruments and it is difficult to effectively shorten the operation time.

[0004] The disadvantages of the existing technology are that the operation time is long, the success rate of the operation is low, the incision is not smooth, the wound suture is not beautiful, and the suture (anastomosis) is difficult to control. For doctors who lack clinical experience, when performing circumcision surgery, complications such as the frenulum length being too long or too short often occur. Summary of the invention
