Patent ID: 8419799

Claim:
An assembly tool for assembly of a proximal body component of a prosthesis to a distal stem component of the prosthesis for use in joint arthroplasty, the tool comprising: a tube component defining a longitudinal opening therethrough and including: a tube component handle located at an end thereof and configured for manually grasping to hold the tube component in a fixed position relative to the distal stem component; and a tube-prosthesis contact surface located at an opposite end relative to the tube component handle, wherein the tube component contacts the proximal body component at the tube-prosthesis contact surface; a rod component including: a sliding portion movably received within the longitudinal opening of the tube component for rotation and translation relative to the tube component; a rod component handle located at an end of the rod component and configured for manually grasping to rotate the rod component relative to the tube component; and an operative portion located at an opposite end relative to the rod component handle and configured to operably engage the distal stem component such that the distal stem component translates relative to the proximal body component as the rod component translates relative to the tube component; and a relative motion feature defined between the tube component and the rod component, the relative motion feature converting torque applied to the rod component through the rod component handle into translation of the sliding portion of the rod component relative to the tube component.
