Background

The prepuce is too long and phimosis is a common reproduction problem for men. With the continuous improvement of living standard and health consciousness of people, higher requirements are put forward on self reproductive health. The redundant prepuce is easy to store dirt and dirt, and if the prepuce is not cleaned in time, the inflammation of glans prepuce and the penile inflammation can be caused, the normal couple life is influenced, the chances of the sexual complicated with the cervicitis and the cervical cancer are increased, and various problems such as the penile cancer, the sterility and the premature ejaculation can be caused. Circumcision is an effective method for treating redundant prepuce and phimosis. A great deal of research in recent years shows that the male circumcision has great significance for reducing male penis skin infection and urinary tract infection, reducing the incidence rate of adult male balanitis and the like, reducing the incidence rate of vaginal infection and cervical cancer of a partner, and even preventing sexually transmitted diseases including AIDS, tumors of a reproductive system and the like.

Currently, manual circumcision and circumcision anastomat methods are generally adopted for treating the redundant prepuce. Manual circumcision adopts manual cutting and suturing, although a plurality of ways exist, the incisal margin condition after the operation completely depends on the level and skill of doctors, the prepuce incision is irregular and not beautiful, the requirement of an operator cannot be met, and the operation time is long. The existing circumcision anastomat has the characteristics of smooth incision, short operation time and simple and convenient operation, but still has certain defects.
