Abstract
Abstract A circumcision instrument according to this invention comprises a pair of crossed members and a pivot pin fixed between the crossed members allowing for movement of the crossed members toward and away from each other about a common axis, wherein the crossed members further comprise a handle with a finger loop at the proximal end of the crossed members, a clamping tab extending from each finger loop, angular facets on the side of each clamping tab and a jaw at the distal end of the cross member with an upper surface providing a surface along which a cutting instrument may be moved to sever tissue clamped between the jaws wherein the lower surface of the jaws are partially cut away forming a clamping surface on the inner surface of the jaw wherein the jaws of the circumcision instrument close such that tissue is crushed without completely severing the tissue. The circumcision instrument of the present invention offers enhanced safety, simplicity, ease of use, cost effectiveness and reduced surgical time. The circumcision instrument of the present invention is meant to minimize potential complications during circumcision and maximize efficiency. The circumcision instrument according to this invention is also part of a sterile prepackaged circumcision kit for use during the circumcision procedure.
