Abstract
A bone broach is formed from a plurality of substantially planar members which are positioned adjacent to each other with each of the substantially planar members attached to at least one other substantially planar member. At least some of the substantially planar members defines at least one cutting profile at its perimeter. The plurality of substantially planar members include a first group of substantially planar members defining planes which are substantially parallel to each other, and at least one additional substantially planar member defining a plane which is angled relative to the planes defined by the first group of substantially planar members.
Claims23
A bone broach comprising a plurality of substantially planar members which are positioned adjacent to each other, in which each of the substantially planar members is attached to at least one other substantially planar member, and at least some of the substantially planar members defines at least one cutting profile at its perimeter, the plurality of substantially planar members comprising:
- a first group of substantially planar members defining planes which are substantially parallel to each other, and
- at least one additional substantially planar member defining a plane which is angled relative to the planes defined by the first group of substantially planar members.
A method of manufacturing a bone broach , the method comprising:
- (a) preparing a plurality of substantially planar members of which at least some define at least one cutting profile at their perimeters,
- (b) arranging the plurality of substantially planar members into:
- a first group of substantially planar members defining planes which are substantially parallel to each other, and
- at least one additional substantially planar member defining a plane which is angled relative to the planes defined by the first group of substantially planar members, and
- (c) joining the plurality of substantially planar members together.
