The Shangring
Originally known by the name “Shenghuan”, this circumcision device first appeared at the Hong Kong International Fair of Technology in 2003. Since then it has frequently been confused with the Zhenxi Ring, which is remarkably similar in appearance but functions somewhat differently.

The Shangring’s inner component is fitted over the glans and the foreskin is drawn forward over it. The outer component is then applied to the external surface of the penis. The knife-edge shape of the outer ring crushes both the outer and inner foreskin; this process is facilitated by the soft inset embedded into the structure of the inner component. A certain degree of skill appears to be required in order to align the two components correctly. Nevertheless, the manufacturers claim a fitting time of around five minutes.
At the outset the device serves to prevent bleeding; there is no need for sutures. It is worn for about seven days, during which time necrosis will occur in a manner similar to all fit-and-wear clamps. The final scar line develops at the crushing point of the ring, not at the position of the cut.
It is important to note that the Shangring device provides no protection whatsoever for the glans. Thus, in the interests of patient safety, the use of surgical scissors rather than a scalpel should be considered.
The resulting style will be moderately low and totally loose; there is no opportunity with this device to tension the shaft skin and thus create a tight style. The frenulum is not removed; if that is required then it should be done as a separate, prior procedure.
Accurate choice of the appropriate size device is important when using the Shangring. The device comes in 22 different sizes ranging from 11mm to 38mm inside diameter of the outer component.
It is sterilised by gamma radiation (Cobalt-60 exposure) and has a shelf life of 3 years.
