The ShangRing is comprised of two concentric plastic rings: an inner ring and outer ring. The inner ring lined with a soft silicone pad, leaving a smooth, nonbioreactive surface against the surgical wound. The outer ring consists of two halves that are hinged together at one end and contain a locking clasp on the other.

How to use ShangRing?

  

Before the procedure, correct sizing of the ShangRing is done using a penile circumference measuring tape. In the event that a patient falls between two sizes, the larger size should be used.

The ShangRing procedure is as followed:

a. The inner ring is placed around the penis to the level of the coronal sulcus.

b. After placing clamps on the foreskin at the 3, 6, 9, and 12 o’clock positions, the foreskin is carefully everted over the inner ring.

c. The outer ring is placed over the inner ring and closed to the first stop of the clamp, thus sandwiching the foreskin between both rings.

d. The excess foreskin is excised using curved scissors.

e. Afterwards, using a scalpel blade, 10 to 12 slits are made in the foreskin on the underside of the ring at the 2, 5, 8, and 11 o’clock positions; these slits are necessary to allow the skin to spread as healing occurs and to allow for expansion of the scab.

f. The wound is subjected to sustained circumferential pressure and the skin edges are juxtaposed underside to underside rather than edge to edge. The ring is left in place for around 7 days.

How to remove the ring?

Removal of the ShangRing.

a. The outer ring is unlocked and removed using the ShangRing removal tool.

b. The inner ring is gently separated from the wound margin and cut at the 3 and 9 o’clock positions using special scissors that possess a blunt tip and recessed cutting edges.
