Abstract
A clamp assembly fixes a navigation tracker to a bone. The assembly includes first and second clamp jaws. The second clamp jaw is pivotal about a first fixed pivot. A linear driver includes a shaft. A first linkage is pivotal at one end about a second fixed pivot and coupled at an opposing end to the shaft at a first moving pivot. A second linkage is coupled at one end to the shaft at the first moving pivot and coupled at the other end to the second clamp jaw at a second moving pivot. The linear driver linearly translates the shaft to apply force to the first moving pivot in a first direction to pivot the second clamp jaw towards the first clamp jaw and in a second direction opposite to the first direction to pivot the second clamp jaw away from the first clamp jaw.
