Content
In the illustrated embodiment, the cutting tool 1026, cutter guide 1010, driver, and optionally the handle 1004 cooperate to provide the rigid structure of the first-class lever. The lever arm 1306 is the distance between the pivot axis 1014 and where an effort force (FE) is applied to the lever. The distance of the lever arm 1306 has a measurable length. The load arm 1308 is the distance between the pivot axis 1014 and where a load force (FL) is applied to the load (e.g., the bone 1304). The distance of the load arm 1308 has a measurable length. Generally, the FL will be a point where the cutting section 1222 contacts the bone 1304. As the cutting section 1222 encounters more bone material the FL may move more distally. The bone 1304 contacts the cutting tool 1026 near the distal end 1204 of the cutting tool 1026.
