A resection guide can be configured to guide a resection tool toward a graft source, and can include a resection guide body made from a first material, and a guide member made from a second material. The second material is harder than the first material.
Claims26
A resection guide configured to guide a resection tool toward a graft source, the resection guide comprising:
- a resection guide body defining:
- an external, outer body surface;
- an inner body surface opposite the outer body surface and elongate along a longitudinal direction, the inner body surface having a first terminal edge and a second terminal edge offset from the first terminal edge by a first dimension along a select direction that is perpendicular to the longitudinal direction, and the inner body surface being concave from the first terminal edge to the second terminal edge;
- and
- first and second resection guide openings that extend from the inner body surface through the outer body surface, wherein the first and second resection guide openings define respective first and second graft resection axes that are configured to receive a portion of the resection tool and guide the resection tool along the respective first and second resection guide openings so as to resect a graft portion from the graft source, the resection guide body defining, for each one of the first and second resection guide openings, first and second inner surfaces that at least partially define the one of the first and second resection guide openings, wherein the second inner surface is spaced from the first inner surface along a respective one of the first and second graft resection axes, and the second inner surface is offset from the first inner surface by a minimum dimension with respect to the select direction, the minimum dimension being greater than the first dimension.
