Abstract
A device for trimming an osteochondral plug graft to an implantable configuration, includes a blade assembly terminating in a configured leading cutting blade and a plug graft housing comprising a substantially longitudinal holding sleeve having a bore and oriented complementarily to the longitudinal structure of the blade assembly to receive the longitudinal structure within the sleeve bore with the assembly cutting blade in close tolerance along an inner bore surface of the longitudinal housing structure.
Claims19
A device for trimming an osteochondral plug graft to an implantable configuration, comprising:
- a housing with a housing through bore that forms a continuous passageway in the housing, said housing defining an impact guide configured to receive a blade plate assembly including a plurality of alternatively sized cutting blades positioned thereon, said blade plate assembly configured to slide into said impact guide to selectively align one of said alternatively sized cutting blades with said continuous passageway, the blade plate assembly including a plurality of alternatively sized openings, each of the openings having one of the cutting blades positioned therein, each of the openings having a raised lip at a boundary thereof;
- a selected longitudinal cutting blade of said blade plate assembly terminating in a configured leading cutting edge;
- an impactor connected to the blade plate assembly at an end opposite the leading cutting edge;
- and
- a substantially longitudinal plug graft holding sleeve nestled within the housing through bore and having a sleeve bore to hold a plug graft in a shearable orientation aligned within the continuous passageway and oriented to coaxially receive the selected longitudinal cutting blade within the sleeve bore with the blade in close tolerance along an inner bore surface of the holding sleeve to shear the plug graft.
