Midline referencing femoral sizing caliper |
摘要 |
A sizing caliper for facilitating the selection of a femoral component of a knee prosthesis includes a caliper body, a drill guide body, a stylus tower and a graduated stylus slidably coupled to the stylus tower. The caliper body, the stylus tower and the two drill guide body portions are configured to be slidably linked to each other, whereby as the caliper body and the stylus tower are linearly displaced, in opposite directions along the longitudinal axis L of the sizing caliper, relative to the two drill guide body portions, the caliper body and the stylus tower are linearly displaced at an equal rate relative to the drill guide body portions and the drill guide holes remain located at the midpoint of an anterior/posterior dimension defined by the distance between the tip of the stylus and the base portion. |
