Abstract
A surgical tool, for use in a ligament repair procedure after rupture of the ligament, the tool comprising; a handle having a first end and a second end, the second end capable of receiving and retaining a cutting guide assembly; the cutting guide including an outer wall which defines an internal, space in which there is located a base; a passage defined by the outer wall and base and which allows access for a cutting implement to bone; and at least one formation extending from the cutting guide which locates the tool against bone during cutting; wherein the bone cutting guide, guides the cutting implement through said passage to enable cutting of a bone section which is separated from surrounding bone.
Claims31
A surgical tool for use in a ligament repair procedure after rupture of the ligament, the tool comprising:
- a handle having a first end and a second end, the second end capable of receiving and retaining a cutting guide assembly;
- the cutting guide including an outer wall which defines an internal space in which there is located a base;
- a passage defined by the outer wall and base and which allows access for a cutting implement to bone;
- and at least one formation extending from the cutting guide which locates the tool against bone during cutting;
- wherein the bone cutting guide, guides the cutting implement through said passage to enable cutting of a bone section which is separated from 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 hone 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.
An assembly for use in the re attachment of a ruptured ligament, the assembly comprising;
- a cutting tool operable by a power drill and having a first end terminating in a cutting profile and a second end attachable to the power drill, the cutting tool capable of creating by operation of the cutting profile a core of bone to which is attached part of a ligament requiring repair,
- an instrument which receives a rod capable of entering a through passage in the instrument;
- the rod having a leading end which is capable of entering the cutting tool to engage the bone core to allow advancement and retraction of the bone core;
- wherein the bone cutting tool 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 tool to be wider at a distal end than at a proximal end.
