Abstract: A surgical instrument is described which comprises an alignment guide having a first part including a distal end and a second part having a proximal end. The first part is attached to the second part by a pivot mechanism so that the first part can be tilted relative to the second part. A brace is attached toward the proximal end of the alignment guide for attaching the instrument to a limb of a patient. A component is attached toward the distal end of the alignment guide. The pivot mechanism is configured so that tilting the first part does not substantially change the separation between the component and the brace.

Abstract: A surgical instrument which can be attached to a patient is described. The instrument includes an alignment guide having a distal end and a proximal end. A brace is attached toward the proximal end of the alignment guide for attaching the instrument to a limb of a patient. The brace comprises a pair of opposed members, each member being shaped to hold a respective bony part of the patient on either side of the patient. At least a part of the brace is made of a resilient material allowing the brace to grip the patient in use.

Abstract: A femoral instrument for use in the intramedullary canal is described and includes an intramedullary rod having a tip at a free end. A body is attached to the intramedullary rod and has a face with a bone abutting portion. A centraliser mechanism is located within the rod and is operable to deploy and retract a plurality of members to engage and disengage an inner surface of the intramedullary canal.

Abstract: The present invention provides a speculum comprising a body (100), an opening (20), a first blade (2) pivotably secured to the body and a second blade (3) that is integral with the body. The blades are located at opposed sides of the opening. The first blade is pivotally secured with respect to the body by means of pivot pins. The first blade is movable between a first retracted position in which it lies adjacent to the second blade and a second extended position in which it is spaced apart from the second blade. A mechanism (5, 41) is also provided that is configured to move the first blade (2) from the first position to the second position. When the first blade is in the extended position, there is an inspection channel (20) formed that extends through the opening and between the blades. The mechanism for moving the first blade is preferably located substantially outside the periphery of the opening when the first blade is in the extended position.
