Abstract: A clamp having a U-shaped clamp body which engages a profile such as a rectangular pipe on three sides, while a fourth side of the profile is engaged by a bolt which is secured by a nut and extends through conical holes in the free legs of the clamp body. Conical washers on the bolt engage the conical holes on the far side from the pipe, meaning that the bolt is located eccentrically in the holes. Tightening the bolt the nut makes the clamp body squeeze the top side and the bottom side of the pipe. The conical washers in the conical holes make the bolt squeeze the pipe in the direction of the back side of the pipe. The pipe is thus squeezed from all sides.

Abstract: The present invention is directed to a circumcision dressing, adjustable in circumference, which is placed around the subglanular or subcoronal region of a penis on its mucosal aspect. The dressing comprises an inner arcuate member, or ring, which is adapted to be positioned between the prepuce and shaft of the penis parallel to the corona of the glans. This inner ring is discontinuous, preferably at its dorsal aspect, to allow for insertion of an elongate hollow connector piece to increase circumference for different sized penises, and is made from polymer, rubber, or metal. If desired, the inner ring may bear a guard flange which extends anteriorly beneath the prepuce to protect the penis from injury during the circumcision procedure. After this first ring is applied to the mucosal aspect of the prepuce with the foreskin retracted, the prepuce is reduced, or pulled forward. A second ring, or outer arcuate member, of polymer, rubber, or metal is then applied.
