Abstract

A disassembly tool for disassembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member having a radial portion operably associated with the first component and adapted to exert a radial force on the first component. A second member operably associated with the second component is also included and the second member has a second member longitudinal axis. A drive mechanism is coupled to the second member, such that as the drive mechanism is activated, the second member exerts a force against the second component in the direction of the longitudinal axis. Such exertion of force against the second member further causes the second member to move relative to the first member along the second member longitudinal axis.

Claims (9)

1. A disassembly tool for disassembly 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 having a radial portion operably associated with the first component and adapted to exert a radial force on the first component;

a second member operably associated with the second component, the second member having a second member longitudinal axis; and

a drive mechanism coupled to the second member, such that as the drive mechanism is activated, the second member exerts a force against the second component in the direction of the longitudinal axis, wherein such exertion of force against the second member further causes the second member to move relative to the first member along the second member longitudinal axis

wherein the first member has a distal end and further includes a sleeve having a tapered distal portion and an expansion member at the distal end of the first member, the expansion member including a cylindrical inner wall, wherein the tapered distal portion of the sleeve engages the cylindrical inner wall, such that the expansion member engages a recess of the first component and expand into the recess of the first component.

2. The disassembly tool of claim 1 , wherein the expansion member is a radially expanding collet.

3. The disassembly tool of claim 1 , further comprising a stationary handle and the drive mechanism including a moveable handle.

4. The disassembly tool of claim 3 , wherein the stationary handle couples to the first member and the moveable handle couples to the second member.

5. The disassembly tool of claim 1 , wherein the second member includes a distal portion adapted to fit within a recess of the second component.
