RESURFACING REAMER WITH CUTTING STRUTS |
摘要 |
Disclosed is a guided orthopedic bone reamer (10a) for cutting a profile relief shape (21a) into a joint bone (20). The reamer (10a) has a cutting head (30a) and an axial guide assembly (70). The cutting head (30a) has a profile cutting form (24a) with a rim (34) and an apex (38a). The apex (38a) connects to the cutting form (24a) by a set of struts (94). An axial guide assembly (70) has one end (44a) fixed to the apex (38a) and at the other end has a bayonet mechanism (76) connectable to a drive handle. Rim cutting teeth (36a) are set into the rim (34) to cut a cylindrical profile (21a), and bevel cutting teeth (96) integral to the struts (94) cut a bevel (25) onto the cylindrical form (21a) cut into the bone (20). A guide pin bore (12a) passes through the apex (38a)and the guide assembly (70) concentric with the axis of rotation (18) to receive a guide pin (14) to guide the reamer (10a) in cutting alignment relative to the joint bone (20) to be cut.
