Patent ID: 7695479

Claim:
A femoral sizer for sizing a femur, comprising: a stylus that moves between a first engaging position relative to the femur and a second non-engaging position, the stylus having an arm portion and a finger portion, the arm portion defining a first longitudinal axis between a first proximal end and a first distal end, the finger portion having an entire length between a second proximal end and a second distal end, the second distal end defining a terminal tip of the stylus, the finger portion being linear along its length and defining a second longitudinal axis wherein the stylus transitions between the arm portion and the finger portion at a transition defined at the first distal end and the second proximal end, wherein the first and second longitudinal axes are parallel in the first non-engaging position and diverge at the transition in the second engaging position wherein the terminal tip is engagable with an anterior surface of the femur during sizing of the femur and wherein the first engaging position and the second non-engaging position are distinct; wherein the transition is defined by a pivot pin coupled through the first distal end and the second proximal end, wherein the finger portion rotates relative to the arm portion about the pivot pin between the engaging position and a non-engaging position; and wherein the pivot pin defines a pivot axis, wherein the pivot axis is substantially transverse to the first and second longitudinal axes and is non-intersecting with the femur.
