Abstract

Abstract An orthopaedic instrument for use in biopsy or similar procedures comprises three elongate members (10, 32 20,30) of different lengths mutually longitudinally and slidably interconnected as the inner (30), middle (20) and outer (10) members in a separate telescopic assembly; the inner member being the longest, having a knob handle (32) at one end of the assembly, and being solid at the other end; the middle member being a sleeve (21) having a T-bar handle (22) at said one end a short portion (24) of reduced wall thickness terminating in hole saw teeth (23) at said other end; and the outer member being the shortest and a sleeve (11) having a pistol grip handle (12) at said one end and bone-penetrating projections (13) from said other end. <IMAGE>

CLAIM 1. An orthopaedic instrument comprising three elongate members of respectively different lengths, mutually longitudinally and rotatably slidably interconnected as inner, middle and outer members in a telescopic assembly, and being successively separable from the assembly at one end thereof and individually projectable at the other end thereof; the inner member being the longest member, having a handle of knob form at said one end, and being solid and blunt at said other end; the middle member being a sleeve having a handle of T-bar form at said one end and a relatively short longitudinal portion of reduced wall thickness terminating in teeth therearound at said other end to form a hole saw; and the outer member being the shortest member and in the form of a sleeve having at said one end a handle of pistol grip form and greater transverse extent than said T-bar handle, and having at said other end longitudinal projections to penetrate the bone.
