Abstract
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 includes a first member operably associated with the first component and a second member operably associated with the second component. The second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess.
Claims14
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;
- and a second member operably associated with the second component;
- wherein the second member includes a cap having a threaded recess and further includes a threaded rod configured to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess, wherein the second member includes a tensile bar that is sized and shaped to break at a predetermined force and the second member includes a housing configured to house the tensile bar, the housing including an upper restraint, a lower restraint, and a pivot pin coupling the upper restraint to the lower restraint, and the lower restraint including a slot, such that when the upper restraint is pivoted via the pivot pin, the tensile bar swings out of the slot in the lower restraint.
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, including a tensile bar configured to break at a predetermined force, wherein the second member includes a housing configured to retain the tensile bar after the tensile bar breaks, wherein the housing including an upper restraint, a lower restraint, and a pivot pin coupling the upper restraint to the lower restraint, and the lower restraint including a slot, such that when the upper restraint is pivoted via the pivot pin, the tensile bar swings out of the slot in the lower restraint.
