Osteotomy guide

Abstract

A new osteotomy guide for guiding saw blades when making an osteotomy cut in a bone is disclosed. Osteotomy is the surgical dividing of bone. The guide includes a base, a pair of prongs and a handle. The base includes a bore for passage of a K-wire or other guide pin. The prongs define a slot for passage of a surgical saw blade. The bore and slot are deeper than prior art osteotomy guides and thus stabilize the guide and the blade relative to the guide pin so that the plane of the saw blade remains parallel to the guide pin. This ensures that in multiple-cut osteotomy procedures all the planes of opposing cuts will exactly coincide when the cut ends are reattached.

I claim: 
     
       1. An osteotomy guide for guiding an osteotomy blade during cutting of bone, comprising: (a) a guide pin holder sized and shaped such that the guide pin holder can rotate about a guide pin while being held at a first fixed angle relative to the guide pin; and,   (b) an osteotomy blade stabilizer connected to the guide pin holder such that the osteotomy blade stabilizer will be held at a fixed angle relative to the guide pin, the osteotomy blade holder sized and shaped such that the osteotomy blade can move translationally while the plane of the osteotomy blade is held at a second fixed angle relative to the guide pin.   
     
     
       2. The osteotomy guide according to claim 1, wherein the first fixed angle and the second fixed angle are both 180° so that the plane of the osteotomy blade is held parallel to the guide pin. 
     
     
       3. An osteotomy guide for guiding an osteotomy blade during cutting of bone, comprising: (a) a base defining a bore, the bore having a diameter such that it will rotatably hold a guide pin and having a depth such that the base will be held at a fixed angle relative to the guide pin;   (b) extending from the base, a pair of prongs defining a slot parallel to the bore, the slot having a width and depth such that the plane of the osteotomy blade will be held parallel to the guide pin as the osteotomy blade moves up and down through the slot; and,   (c) a handle connected to the base.   
     
     
       4. An osteotomy guide for guiding an osteotomy blade during cutting of bone, comprising: (a) a base defining a bore, the bore having a diameter such that it will rotatably hold a guide pin and having a depth such that the base will be held at a fixed angle relative to the guide pin;   (b) extending horizontally from the base, a pair of prongs defining a slot at a fixed angle relative to the bore, the slot having a width and depth such that the plane of the osteotomy blade will be held at a fixed angle relative to the guide pin as the osteotomy blade moves up and down through the slot; and,   (c) a handle connected to the base.
