Abstract:
1. A device for positioning a bone cut on a tibia, the device comprising: a tibial attachment member; a coupler moveably attached to the tibial attachment member; a rotationally moveable arm rotationally attached to the coupler; a swing arm coupled with the rotationally moveable arm via an axle such that a free end of the swing arm is configured to swing from an anterior position, in which the free end faces an anterior surface of the tibia, to a side position, in which the free end faces a side of the tibia; a light emitting member coupled with the swing arm at or near the free end for emitting light along the tibia, the light emitting member emitting light in a linear or planar configuration; a varus/valgus adjustment member for adjusting the rotationally moveable arm to direct the emitted light approximately along a midline of the anterior surface of the tibia; an anterior/posterior adjustment member for adjusting the coupler in an anterior/posterior orientation relative to the tibial attachment member to direct the emitted light approximately along a midline of the side of the tibia; and a tibial bone resection level adjustment member for selecting a level for resecting the tibia.
