ZSR circumcision uses a special circular clamping device to remove the foreskin and compresses the blood vessels at the incised tissue, thus minimizing postoperative bleeding. 

ZSR circumcision device consist of 2 main components; the inner bell and outer bell. The inner bell is designed to protect the inner glans penis and the outer bell consists of a blade to cut the foreskin and staples to close the wound. 

Firstly, the doctor will stretch the foreskin and place the inner bell to protect the glans of penis. Then, the rest of the device with the outer bell is screwed onto the inner bell.  Once the stapler is fired, the foreskin is separated from the penis, and the wound edges will be held together by a series of small staples and a silicon ring. The wound will be bandaged for a few days while the staples will be in place for an average period of one week before they drop spontaneously.
