A surgical device and method are disclosed for harvesting bone portions. The device has a guide which facilitates control of at least one dimension of the harvested portion. Embodiments of the invention are particularly, but not exclusively, suited to harvesting bone portions for graft surgery, particularly patella tendon grafts.

Bone harvesting device and method

A tunnel guide apparatus and method for forming two convergent tunnels in a bone. The apparatus includes a first bullet member for aiming a guide pin to form a first tunnel in the bone. A second bullet member adjustably connects to the first bullet member, for aiming a guide pin to form a second tunnel in the bone such that the first and second tunnels are convergent. The two bullet members are joined by a guide arm member disposed on a guide arc member such that the first and second bullet members and the guide arm member are adjustable on the guide arc member to form the two tunnels.

Convergent tunnel guide apparatus and method

The invention relates to an anchoring device for urging a ligament transplant against the wall of a bone hole during ligament replacement and for fixing the anchor in position in the said bone hole. The device has a first component and a second component designed for mutual sliding co-operation between a first anchor inserting position and a second fixation position. The sliding co-operation is provided along respective parallel inner mating surfaces of each component which surfaces are each in angular relation to the respective component outer surfaces and in opposed angular relation to each other so that in the anchor insertion position the width of the said anchoring device is in an elongate narrow mode with respect to a bone hole and, in the fixation position, the width of the said anchoring device is in a compressed wide mode to thereby urge the ligament against the wall of the bone hole. A method of ligament fixation in a bone hole is also disclosed.

Anchoring device

The invention describes a bone anchor comprising a head region and supporting legs and a method for soft tissue-bone grafting using the said bone anchor . A hole is drilled through cortical bone forming a socket in a cancellous bone , and the bone anchor is inserted therein thereby trapping ligaments and between the radially outermost portion of the anchor and the inside surface of the socket . An optional expansion peg (not shown) is inserted into a hole within the bone anchor , thereby causing the proximal ends of the legs of the bone anchor to expand radially causing the ligaments and to closely abut the cancellous bone thereby encouraging the grafting process.
