Abstract
An impactor (100) for transferring an impaction force to a prosthesis (4) coupled to a prepared distal end of a bone (6). The impactor (100) comprises a connector (154) arranged to couple to a prosthesis (4) and an impactor handle (134). The impactor handle (134) defines an impaction axis (110) extending into the prosthesis (4) such that an impaction force applied to the impactor handle (134) is transferred to the prosthesis (4) along the impaction axis (110). When the connector (154) is coupled to a prosthesis (4) the point at which the impaction axis (110) extends into the prosthesis (4) is spaced apart from the coupling between the connector (154) and the prosthesis (4).
Claims15
An impactor for transferring an impaction force to a prosthesis in contact with a prepared distal end of a bone, the bone having a longitudinal axis, the impactor comprising:
- a connector couplable to the prosthesis at a first location;
- and
- an impactor handle connected to the connector, the impactor handle having an impaction axis spaced apart from the first location along an axis perpendicular to the longitudinal axis.
A method of implanting a prosthesis, the method comprising the steps of:
- surgically preparing an end of a bone to receive a prosthesis;
- fitting the prosthesis over the prepared end of the bone;
- coupling an impactor the prosthesis at a first location, the impactor comprising a connector that couples to the prosthesis, and an impactor handle defining an impaction axis spaced apart from the first location along an axis perpendicular to the longitudinal axis;
- and
- applying an impaction force to the impactor handle, the impaction force being transferred to the prosthesis along the impaction axis.
