Joint revision surgery osteotome blades and surgical chisel blades
The present application is directed to a Joint Revision Surgery Osteotome Blades and Surgical Chisel Blades which includes a surgical osteotome blade guide block which has a plurality of rearward blade guide slots, a central cavity and a plurality of forward guide slots having a two-way adjustable L-shaped guide plate. The surgical osteotome blade guide block central cavity houses a stem trunnion securing and is secured to the prothesis to be extracted. The guide blade block is secured to the trunnion of the prosthesis to be extracted using a stem trunnion securing member housed within the guide block. Straight, curved, flexible and rigid and compound curved osteotome blades are guided by the blade guide slots to cut the implant free from the bone. The Joint Revision Surgery Osteotome Blades and Surgical Chisel Blades facilitates rapid, efficient and complete removal of an existing prosthesis during joint revision surgery, and significantly increases positive medical outcomes for joint revision procedures.
1 . A joint revision surgery medial calcar osteotome blade comprising:
(a) a cutting edge the blade having a longitudinal axis and a curvature about the longitudinal axis, such that the cutting edge is disposed symmetrically about the longitudinal axis, and further wherein said cutting edge is beveled on both sides;
(b) a flexible blade shaft; and
(c) a blade insertion plate including two blade locking slots.
2 . The joint revision surgery medial calcar osteotome blade according to claim 1 , wherein said blade terminates in a pointed tip that lies on the longitudinal axis.
3 . The joint revision surgery medial calcar osteotome blade according to claim 2 , wherein said flexible blade shaft is straight.
4 . The joint revision surgery medial calcar osteotome blade according to claim 2 , wherein said flexible blade shaft is elongated along a longitudinal axis of the blade.
5 . The joint revision surgery medial calcar osteotome blade according to claim 1 , wherein said cutting edge comprises a first cutting edge portion and a second cutting edge portion disposed symmetrically about the longitudinal axis of the blade wherein a point on the first cutting edge portion and a point on the second cutting edge portion are symmetrically located about the longitudinal axis and are located distal to the pointed tip of the blade centrally located on the longitudinal axis of the blade.
6 . The joint revision surgery medial calcar osteotome blade according to claim 5 , wherein said flexible blade shaft is elongated along a longitudinal axis of the blade.
