Abstract
This application relates generally to broaches. More specifically, this application relates to broaches used to shape bores in bone. The broaches can shape the bores to receive an implant and also cut additional tubes or channels for receiving bone graft material and/or biologic aids.
Claims22
A broach for shaping a bore in bone to receive an implant, the broach comprising:
- an elongate body with a proximal end, a distal end, at least three faces between the distal end and the proximal end, a plurality of apices formed at the junctions between adjacent faces, and a longitudinal axis;
- a plurality of cutting surfaces located on the distal end of the elongate body for shaping the bore to receive the implant, wherein the plurality of cutting surfaces are oriented along the plurality of apices and become progressively smaller in size towards the distal end;
- and
- a plurality of additional cutting surfaces aligned with the plurality of apices for cutting channels in the bore to receive a bone graft material.
A method for inserting an implant in bone, the method comprising:
- drilling a bore into the bone;
- inserting a broach to shape the bore to receive the implant and to form channels for receiving a bone graft material;
- inserting the implant into the shaped bore;
- and
- filling the channels with a bone graft material.
A broach for shaping a bore in bone to receive an implant, the broach comprising:
- an elongate body with a proximal end, a distal end, at least three faces between the distal end and the proximal end, a plurality of apices formed at the junctions between adjacent faces, and a longitudinal axis;
- a plurality of cutting surfaces located on the distal end of the elongate body for shaping the bore to receive the implant, wherein the plurality of cutting surfaces are oriented along the plurality of apices and become progressively smaller in size towards the distal end;
- and
- a tapered distal tip portion at the distal end of the elongate body that tapers to a distal opening of the lumen.
A method for inserting an implant in bone, the method comprising:
- inserting a guide pin into the bone;
- inserting a sharp tipped broach over the guide pin to create a cavity for receiving the implant, wherein the cavity can be formed without first drilling a bore into the bone over the guide pin;
- and
- inserting the implant into the cavity.
