Tool assembly including a cutting tool and cutting guide

The cutting assembly according to claim 8 wherein cutting is enabled by reciprocating rotation of the working end.

A cutting tool for a cutting assembly comprising the tool and a cutting guide, the cutting tool enabling creation of a tapered cut in a hard material, the tool comprising a tool body having a first end which includes a profile enabling operable engagement of the cutting tool with a power tool;

• a second working end including an arcuate cutter having a tapered region extending distally, the working end including at least one cutting region formed by an array of cutting teeth.

A cutting guide for a cutting assembly comprising a cutting tool and the cutting guide, the cutting tool enabling creation of a tapered cut in a hard material, the tool comprising a tool body having a first end which includes a profile enabling operable engagement of the cutting tool with a power tool;

• a second working end including an arcuate cutter having a tapered region extending distally, the working end including at least one cutting region formed by an array of cutting teeth;
• the cutting guide comprising a guide body having a proximal end and distal end, the distal end including an arcuate wall having a tapered region extending distally and shaped to enter and fit a first cut formed by said cutting tool, the proximal end of the guide having a guide opening which receives and guides a secondary cutter to complete the first cut.

An assembly for enabling a tapered cut in bone, the assembly comprising a cutting tool having a first end which engages a powered activation tool and a second curved tapered end which includes a cutting edge profile capable of creating the tapered cut in bone;

• a guide which co-operates with the cutting tool and insertable into a first cut made by the cutting tool;
• the guide including an opening which receives and guides a second cutting implement which makes a secondary cut in the bone, the first and second cuts creating a tapered bone portion releasable from the surrounding bone.

An assembly for use in a ligament reconstruction procedure after rupture of the ligament, the assembly comprising:

• a jig capable of measurement of a length of a tibial bone section measured from a distal entry point to the tibia to a proximal location at which the length of bone is capable of separation form the tibia;
• a guide wire for insertion axially through the bone section such that an entry point in the bone section aligns with a ruptured anterior cruciate ligament;
• a bone cutting guide which has a first end which in use engages a tibial bone surface to be cut and a body which allows the bone section after cutting by the bone cutting element to be wider at a distal end than at a proximal end.
