It is a simple device which consists of 2 concentric plastic rings: the inner ring and the outer ring. The inner ring is lined with a soft silicone pad, which provides a smooth and non-bioreactive surface against the surgical wound. The outer ring consists of 2 halves which are hinged together at the same end. On each side of the halves there is a locking clasp which allows for locking itself with inner ring. When performing circumcision, foreskin will be everted and locked between inner ring and outer ring. Thus, a sandwich including inner ring, redundant foreskin, and outer ring will be formed.
