Patent ID: 7682363

Claim:
An inserter for aiding a surgeon in controlling the installation of a prosthesis cup, the inserter comprising: a) an inserter head having a longitudinally extending bore therethrough; b) a housing comprising a proximal housing end and a distal housing end supporting the inserter head; and c) a drive train at least partially housed inside the housing, the drive train comprising: i) a first lever comprising a first lever proximal end spaced apart from a first lever distal end located adjacent to the distal housing end; ii) a second lever comprising a second lever proximal end located adjacent to the proximal housing end and spaced apart from a second lever distal end; iii) a drive rod comprising a drive rod proximal end space apart from a drive rod distal end that is connectible to a prosthesis cup, wherein the second lever distal end is in a universal joint relationship with the first lever proximal end, and wherein the first lever distal end is in a universal joint relationship with the drive rod proximal end and the drive rod distal end extends through the bore in the inserter head; iv) a first sleeve pivotably connected to the housing, wherein the first lever is in a slidable relationship with a first opening in the first sleeve disposed at an intermediate location between the first lever proximal end and the first lever distal end; and v) wherein the second lever is pivotably supported by the housing; and d) wherein the second lever proximal end is manipulable from a first position spaced from the housing to a second position spaced closer to the housing than the first spaced position to cause the second lever to pivot with respect to the housing and thereby move the second lever distal end away from the distal housing end and to further cause the first lever to move away from the distal housing end along the first opening in the first sleeve as the first sleeve pivots on the housing to thereby cause the drive rod to move along the longitudinal bore in the inserter head with the drive rod distal end moving from a first drive rod position spaced from the inserter head to a second drive rod position closer to the inserter head than the first drive rod position.
