Surgical guide device
First Claim
1. A surgical guide device comprising first and second limbs pivotally connected together, at least one guide sleeve attached to one limb, the guide sleeve having a bore through the sleeve, wherein the guide sleeve is pivotally attached to the limb, and wherein the apparatus has an orientation mechanism adapted to change the orientation of the guide sleeve relative to the limb as the limbs move relative to one another;
- wherein the bore of the at least one guide sleeve is held in a defined orientation by the orientation mechanism, and the axis of the bore of the guide sleeve intersects with the same point on the opposite limb of the device during pivotal movements of the limbs relative to one another;
wherein the first limb comprises two limb portions that are moveable relative to one another; and
wherein the two limb portions are pivotally coupled to the guide sleeve at the distal end of the first limb and to a yoke device at the proximal end of the first limb.

Abstract
A surgical guide device comprises first and second limbs pivotally connected together, with a respective guide sleeve pivotally attached to each limb. Each guide sleeve has a bore through the sleeve that can guide a drill bit or bone fixing for insertion into a fragmented bone portion. The device has an orientation mechanism adapted to change the orientation of the guide sleeves relative to the limbs as the limbs move relative to one another, so as to maintain the orientation of the guide sleeves relative to one another during pivotal movement of the limbs.

15. A surgical guide device comprising first and second limbs pivotally connected together, a respective guide sleeve pivotally attached to each limb, each guide sleeve having a bore through the sleeve, and wherein the apparatus has an orientation mechanism adapted to change the orientation of the guide sleeves relative to the limbs as the limbs move relative to one another, so as to maintain the orientation of the guide sleeves relative to one another during pivotal movement of the limbs;
-
wherein the bore of each guide sleeve is held in a defined orientation by the orientation mechanism such that the axis of the bore of one guide sleeve is always aligned with the axis of the bore of the other guide sleeve on the opposite limb of the device during pivotal movement of the limbs relative to one another; wherein the first limb comprises two limb portions that are moveable relative to one another; and wherein the two limb portions are pivotally coupled to the guide sleeve at the distal end of the first limb and to a yoke device at the proximal end of the first limb.

16. A method of guiding the insertion of a fixing device into a body portion, comprising providing a guide device comprising first and second limbs pivotally connected together to close around the body portion, having at least one guide sleeve attached to one limb, the guide sleeve having a bore through the sleeve, wherein the guide sleeve is pivotally attached to the limb, and wherein the apparatus has an orientation mechanism adapted to change the orientation of the guide sleeve relative to the limb as the limbs move relative to one another,
wherein the bore of the at least one guide sleeve is held in a defined orientation by the orientation mechanism, and the axis of the bore of the guide sleeve intersects with the same point on the opposite limb of the device during pivotal movements of the limbs relative to one another; -
wherein the first limb comprises two limb portions that are moveable relative to one another; and wherein the two limb portions are pivotally coupled to the guide sleeve at the distal end of the first limb and to a yoke device at the proximal end of the first limb; the method comprising closing the limbs of the clamp device around the body portion until the guide sleeve engages the body portion, and controlling the orientation of the guide sleeve relative to the body by means of the orientation mechanism, and inserting a fixing device into the body portion through the bore in the guide sleeve.
