Abstract
An assembly tool for use in assembling orthopaedic prosthetic components is disclosed. The assembly tool includes a frame, a base plate that includes a mounting bracket configured to engage a first end of an orthopaedic prosthetic component and a mechanical actuator configured to apply a compressive load to the orthopaedic prosthetic component.
Claims20
An assembly tool for use in assembling orthopaedic prosthetic components, comprising:
- a frame including a pair of telescopic rods,
- a base plate secured to the telescopic rods, the base plate including a mounting bracket configured to engage a first orthopaedic prosthetic component, and
- a mechanical actuator including (i) a housing secured to the frame, (ii) a ram plate configured to engage a second orthopaedic prosthetic component, and (iii) a drive mechanism coupled to the ram plate,
- wherein the drive mechanism includes:
- a connecting rod coupled to the ram plate,
- a handle rotatively coupled to the housing, and
- a clutch pin that is moveable between (i) an engaged position in which the handle is coupled to the connecting rod such that rotation of the handle causes the ram plate to move toward the base plate and (ii) a disengaged position in which the handle is decoupled from the connecting rod such that the ram plate remains stationary when the handle is rotated,
- wherein when the handle is rotated from a first position to a second position, the handle engages an end of the clutch pin to move the clutch pin from the engaged position to the disengaged position.

An assembly tool for use in assembling orthopaedic prosthetic components, comprising:
- a frame,
- a base plate coupled to the frame, the base plate including a mounting bracket configured to engage a first orthopaedic prosthetic component, and
- a mechanical actuator including (i) a housing secured to the frame, (ii) a ram plate configured to engage a second orthopaedic prosthetic component, and (iii) a drive mechanism coupled to the ram plate,
- wherein the drive mechanism includes:
- a handle rotatively coupled to the housing, the handle being operable to move the ram plate toward the base plate, and
- a locking mechanism configured to prevent rotation of the handle, the locking mechanism including a linkage coupled to the ram plate and a pin, the linkage being moveable between (i) a locked position in which the pin is received in a notch defined in the handle such that rotation of the handle is prevented, and (ii) an unlocked position in which the pin is spaced apart from the notch such that rotation of the handle is permitted,
- wherein the linkage is moved to the unlocked position when a predetermined amount of force is applied to the ram plate in a direction away from the base plate.

A method of assembling orthopaedic prosthetic components, comprising:
- selecting a first prosthetic component having a tapered post,
- inserting the tapered post into a tapered bore of a second prosthetic component,
- positioning the first prosthetic component and the second prosthetic component between a ram plate and a base plate of an assembly tool,
- moving the base plate in a first direction to a first position in which the base plate is engaged the second prosthetic component and the first prosthetic component is engaged with the ram plate,
- advancing the base plate in the first direction to a second position to unlock a handle of the assembly tool,
- locking the base plate in the second position,
- operating the handle to move the ram plate in a second direction opposite the first direction to secure the first prosthetic component to the second prosthetic component.
