Abstract
A tool assembly for extracting a liner from a prosthesis comprising an impactor and a faceplate. The impactor can be configured to receive and transmit a force. The faceplate can be configured to deliver the force from the impactor to the prosthesis to separate the liner from a shell of the prosthesis.
Claims20
A tool assembly for extracting a liner from a prosthesis, the tool comprising:
- an impactor configured to receive and transmit a force, the impactor comprising:
- a handle extending along a longitudinal axis and configured to be impacted on a proximal portion of the handle, the handle including a handle bore extending proximally into the handle from a distal portion of the handle;
- a shaft connected to a distal portion of the handle and extending distally therefrom along the longitudinal axis, the shaft extending into the handle bore to secure the shaft to the handle;
- and
- a coupler connected to a distal portion of the shaft, the coupler including a mating interface;
- and
- a faceplate configured to deliver the force from the impactor to the prosthesis, the faceplate comprising:
- a plurality of arms engageable with an outer shell of the prosthesis;
- and
- a boss releasably couplable to the mating interface to secure the faceplate to the impactor.
