Patent ID: 7189241

Claim:
A femoral broaching apparatus for preparing a femoral cavity using vibration under operation of a fixing guide unit for implantation of a prosthetic joint to a femur, comprising: a fixing guide unit fixed in the femoral cavity by an interference fit; a cavity preparing broach coupled to the fixing guide unit in a longitudinally movable manner; a vibration-generating unit coupled to the cavity preparing broach for allowing the cavity preparing broach to perform the preparing of the femoral cavity under operation of the fixing guide unit; and wherein the vibration-generating unit includes: a vibrating body connected to the cavity preparing broach; a driving motor fixedly mounted in the vibrating body; and a vibrating plate rotatably installed in the vibrating body, the vibrating plate being adapted to rotate upon receiving a rotating force from the driving motor, and to repeatedly displace a rotational center thereof, causing vibration of the vibrating body.
