Abstract:
1. An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty, the tool comprising: a first member operably associated with the first component, the first member defining a first member longitudinal axis thereof; a second member operably associated with the second component, the second member defining a second member longitudinal axis thereof; a washer system coupled to the second member, wherein the washer system includes a first spiral washer and a second spiral washer coupled to the second member and the first spiral washer; and a drive mechanism coupled to the washer system, the drive mechanism coupled to the first spiral washer, such that as the drive mechanism is activated, the washer system rotates about the second member longitudinal axis and expands along the second member longitudinal axis, wherein such movement further causes the second member to move relative to the first member along the second member longitudinal axis, the drive mechanism including a handle and wherein as the handle is rotated, the first spiral washer rotates relative to the second spiral washer and moves along the second member longitudinal axis relative to the second spiral washer; wherein the second member includes a tensile rod includes a portion that is thinner, such that the tensile rod breaks upon a certain amount of tensional force.
