Abstract
An osteotomy guide having a frame and a pair of guide pins, for creating a desired cut in a bone. The frame has an outer frame, and an inner frame which is telescopically mounted within the outer frame. Both the inner frame and outer frame having open ends and a guide pin sleeve. The inner frame and outer frame together define a main slot which is adjustable in length by moving the inner frame with respect to the outer frame. The frame is mounted to the bone by creating anchoring holes in the bone and extending the guide pins through the guide pin sleeves and into the anchoring holes, such that the guide pins are parallel in all planes. A controlled cut is created by using the guide pins as a visual guide or inserting a saw blade through the main slot.
Claims4
An osteotomy guide, for use in controlling a cut by a saw blade in a bone, wherein the prospective cut has a desired location and a desired length, comprising:
- a frame, having a top and a bottom, the frame having an outer frame section and an inner frame section, each of said frame sections having a guide pin sleeve and an open end opposite from the guide pin sleeve, the guide pin sleeves each have a guide pin bore extending vertically through the guide pin sleeve, the guide pin sleeves and guide pin bores are substantially parallel and vertical, wherein a distance between the guide pin sleeves can be adjusted by sliding the inner frame section within the outer frame section, wherein the outer frame section has a pair of outer panels extending between the guide pin sleeve and open end of the outer frame section and defining an elongated outer slot therebetween, the outer slot extends fully between the top and bottom, the inner frame section having a pair of inner panels extending between the guide pin sleeve and open end of the inner frame section and defining an elongated inner slot therebetween, the inner slot extending fully between the top and bottom, the inner panels extending between the outer panels of the outer frame with the inner frame panels substantially parallel to the outer frame panels so that the inner slot and outer slot form a main slot which is longitudinally continuous substantially between the two guide pins sleeves, for allowing the saw blade to extend vertically through the main slot fully from the top to the bottom such that the saw blade is constrained in both longitudinal and transverse directions by the main slot, wherein at least one of the inner frame panels has a lateral protrusion, extending substantially from the open end of the inner frame section substantially to the guide pin sleeve of the inner frame section, wherein at least one of the outer frame panels has a side slot extending from the open end of the outer frame section substantially to the guide pin sleeve of the outer frame section, and wherein the lateral protrusion extends within the side slot to direct slidable movement of the inner frame section with respect to the outer frame section;
- and
- a pair of guide pins, which selectively extend through the guide pin sleeves which direct the guide pins into the bone in a parallel relationship prior to cutting.
An osteotomy guide, for use in controlling a cut by a saw blade in a bone, wherein the prospective cut has a desired location, comprising:
- a frame, having a top and a bottom, the frame having a pair of opposite ends and a guide pin sleeve extending vertically at each of the ends, each guide pin sleeve having a guide pin sleeve bore extending vertically between the top and bottom, the frame having an elongated main slot extending fully between the top and bottom substantially between the guide pin sleeves, the main slot for accommodating a saw blade extending vertically fully through the main slot from the top of the frame past the bottom of the frame into the bone for constraining the saw blade in both transverse and longitudinal directions, wherein the frame comprises an outer frame section and an inner frame section, each of said frame sections having one of the guide pin sleeves and an open end opposite from the guide pin sleeve, the outer frame section having a pair of outer panels extending between the guide pin sleeve and open end of the outer frame section and defining an elongated outer slot therebetween, the outer slot extends fully between the top and bottom, the inner frame section having a pair of inner panels extending between the guide pin sleeve and open end of the inner frame section and defining an elongated inner slot therebetween, the inner slot extending fully between the top and bottom, the inner panels extending between the outer panels of the outer frame with the inner frame panels substantially parallel to the outer frame panels so that the inner slot and outer slot form the main slot, and wherein the main slot can be adjusted in length by sliding the inner frame section within the outer frame section, wherein at least one of the inner frame panels has a lateral protrusion, extending substantially from the open end of the inner frame section substantially to the guide pin sleeve of the inner frame section, wherein at least one of the outer frame panels has a side slot extending from the open end of the outer frame section substantially to the guide pin sleeve of the outer frame section, and wherein the lateral protrusion extends within the side slot to direct slidable movement of the inner frame section with respect to the outer frame section;
- and
- a pair of guide pins, which selectively extend vertically through the guide pin sleeves and into the bone on opposite sides of the prospective cut and attach the to the bone in a parallel relationship, such that the slot is positioned directly above the prospective cut such that the saw blade can be extended through the main slot to cut the bone.
