Surgical saw guide and drill guide
First Claim
1. A set of surgical instruments, for use in an osteotomy procedure, the set comprising:
- a saw guide for guiding a saw while it makes an oblique cut in a long bone to divide it into two fragments; and
a drill guide for guiding a drill bit while it forms a passage in said bone after an initial part of said cut has been made in the bone by the saw;
said saw guide including a seat formation having a concave side for abutting a long bone to be cut, so that the long bone seats in the seat formation, and a guide formation for aligning a saw blade relative to a long bone seating in the seat formation and for guiding the saw blade while it initiates the making of the cut in the bone, the saw guide being in the form of a channel having an outer side which is convex and an interior surface which provides the concave side of the seat formation; and
said drill guide including a bit guide and an anchor connected to the bit guide for insertion into the initial part of the cut in the bone when the initial part of the cut has been made, to align the bit guide relative to the cut, the bit guide defining a guide path for receiving a drill bit and for aligning the drill bit perpendicular to the initial part of the cut while the drill bit forms the passage in the bone.

Abstract
A set of surgical instruments which comprises a saw guide and a drill guide respectively for guiding a saw blade cutting a bone and for guiding a drill bit for thereafter forming a passage in the bone. The saw guide has a seat formation for seating against the bone, and a guide formation for guiding the saw. The drill guide comprises a bit guide and an anchor to align the bit guide relative to the cut. Also provided are a saw guide and a drill guide; and a method of carrying out an osteotomy procedure by making an oblique cut through a long bone at a position where bone portions which are misaligned intersect each other to provide two bone fragments, whereafter they are loosely bolted together and then rotated about the axis provided by the bolting until the misalignment is reduced, after which they are bolted tightly together.
