There are 3 main types of circumcision, traditional circumcision, circumcision, circumcision anastomosis and so on. 1. Traditional circumcision: a procedure that uses local anesthesia and a scalpel to remove the excess part of the foreskin directly, then use an electrocautery to stop the bleeding, and then use absorbable sutures to close the wound. 2. Circumcision: Usually, a ring is used to fix the foreskin inside the penis and foreskin, and the foreskin that needs to be cut off is stuck, and through the cooperation between the ring and the silk thread, the cutting is slowly compressed, so that the excess foreskin is necrotic due to ischemia, and then the excess foreskin will fall off by itself. 3. Circumcision anastomosis: the base of the anastomosis is fixed between the foreskin that needs to be cut, and the cutting function of the anastomosis is utilized to remove the excess foreskin. The anastomosis removes the foreskin with stitches, and there is no need to remove the stitches. In case of phimosis, it is recommended to consult a doctor for timely examination and treatment with the help of a doctor.
