Abstract
Systems and methods are provided for navigated placement of bone engaging elements, such as support pins used to support a cutting block on a bone for resection. In one embodiment, a guide apparatus is configured to be mounted to a bone and provides multi-degree of freedom gross and fine adjustments of a pin guide. The pin guide carries a position tracking element so that its real-time spatial position relative to a location on the bone can be evaluated.
Claims20
A system for accurately guiding placement of a bone engaging element in a bone comprising:
- a guide configured to guide movement of the bone engaging element toward a location on a bone, said guide having a bore through which said bone engaging element may be advanced, and said bore defining a first longitudinal axis;
- and
- a support apparatus configured to support said guide, said support apparatus including;
- a support body mountable to the bone;
- an arm extending from said support body;
- and
- a position adjustment assembly supported on said arm, said position adjustment assembly including (i) a first gross adjustment mechanism configured to permit gross adjustment of said guide in relation to said, support body along a second longitudinal axis, (ii) a first fine adjustment mechanism configured to permit fine adjustment of said guide in relation to said support body along said second longitudinal axis, (iii) a second gross adjustment mechanism configured to permit gross adjustment of said guide in relation to said support body along a third longitudinal axis, (iv) a second fine adjustment mechanism configured to permit fine adjustment of said guide in relation to said support body along said third longitudinal axis, and (v) a third adjustment mechanism configured to permit adjustment of said guide in relation to said support body along said first longitudinal axis,
- wherein said first longitudinal axis is not coincident with said second longitudinal axis,
- wherein said first longitudinal axis is not coincident with said third longitudinal axis, and
- wherein said second longitudinal axis is not coincident with said third longitudinal axis.
