Claims20
A surgical instrument comprising:
- a handle portion;
- and
- a blade portion joined to the handle portion, the blade portion comprising:
- a first cutting surface;
- a second cutting surface joined to the first cutting surface to form a V-shape having a point and a wide portion, such that the cutting surfaces slant up and back from the point, the first and second cutting surfaces defining an aperture extending through the blade portion;
- and
- a top portion extending across the wide portion of the V-shape, the top portion having a handle side proximate the handle portion, the top portion having a front edge opposite the handle side, and the point of the blade portion extending away from the handle portion past the front edge of the top portion;
- and
- a spacer selectively positionable beneath the top portion to space the top portion from a work piece being cut by the first and second cutting surfaces.

- a spacer;
- a guide adapted to assist a surgeon in creating a bone plug extract from a patella;
- and
- a cutting instrument comprising:
- a handle portion;
- and
- a blade portion joined to the handle portion, the blade portion comprising:
- a first cutting surface;
- a second cutting surface joined to the first cutting surface to form a V-shape having a point and a wide portion, such that the cutting surfaces slant up and back from the point, the first and second cutting surfaces defining an aperture extending through the blade portion;
- and
- a top portion extending across the wide portion of the V-shape, the top portion having a handle side proximate the handle portion, the top portion having a front edge opposite the handle side, and the point of the blade portion extending away from the handle portion past the front edge of the top portion;
