ABSTRACT:
An adjustable surgical clamp having an axis that is adapted to releasably engage the outer surface of a cylindrical instrument such as a trocar. An elastomeric sleeve has an outer surface and an inner surface which is sized to frictionally engage the instrument. A constriction member forming a ring around the sleeve is operable between a first position wherein the ring has a first diameter and a second position wherein the ring has a second diameter. A pair of tabs attached to the constriction member are movable relative to each other to operate the constriction member between the first and second positions. A tube extending axially of the constriction member includes a protrusion which may be in the form of a helix, a plurality of annuli or an inflatable balloon enhances the fixed relationship with a body wall.
