Background technique

Foreskin refers to the skin of the penis that is folded into a double layer of skin covering the head of the penis. In infants, the foreskin is longer, and it wraps around the penis so that the glans and the outer opening of the urethra cannot be exposed. It is physiological phimosis, which grows with age. The penis and foreskin develop gradually. In adolescence, the foreskin recedes and the glans is exposed in adulthood. However, in about 30% of adults, the foreskin completely covers the glans of the penis, causing inflammation of the foreskin, affecting the development of the penis, causing inflammation of the penis, and even causing Cancer, premature ejaculation, etc. More and more men are beginning to receive circumcision surgery, which is increasing year by year. At present, the main methods of circumcision surgery are traditional circumcision surgery, laser surgery or some small instruments to let the foreskin fall off due to ischemia. Scorching of the foreskin often occurs with laser surgery. The traditional circumcision operation and the operation with the help of small instruments require high clinical experience of the doctor, and the operation is cumbersome. A slight carelessness will cause excessive bleeding and increase the patient's pain.
