ABSTRACT:
A dissecting device assists in removing a prosthesis from an embedded engagement within a bone. The device includes a cutting tool having a cutting tip and an elongated shank which has a diameter and length selected so as to allow significant lateral flexing. A motor configured to be gripped by one hand of a user, is connected to the cutting tool shank for providing rotational motion to the cutting tool. A handle configured to gripped by another hand of the user has a bearing carrier having a hole therethrough which rotatably receives the shank. The user will move the motor and the handle to guide the cutting tool around the perimeter of the prosthesis to dissect a thin layer between the prosthesis and the bone to release the prosthesis from the bone.
