  • Patent number: 8388690
    Abstract: An osteotomy system, typically for tibial alignment correction, includes a wedge implant and an osteotomy guide. The wedge implant is generally U-shaped and its upper and lower surfaces may be inclined with respect to one another in two orthogonal planes to correct respective misalignments. The osteotomy guide controls cutting of the osteotomy opening and the drilling of a hole defining the apex of the osteotomy, forming a bony hinge about which the osteotomy may be opened.

  • Patent number: 8382763
    Abstract: A detachable cutting tool capture for a cutting block provides a guide surface to convert an open surface block into a slotted block for plying a surgical cutting tool along the surfaces of the guide during a surgical procedure such as a bone resection with a blade. A magnetized catch provides a convenient device for securing the capture and the block together. A triangular cam on the detachable capture in conjunction with a “v” groove in a magnetized lever of the catch permits a pin of the catch to be selectively retracted from or extended into an aperture of the block when the lever is rotated so that when the pin extends, it serves to secure the combined apparatus for cutting. Mating surfaces of the block and capture provide additional structure for supporting the capture with the block to secure them from relative movement.

  • Patent number: 8313491
    Abstract: A chamfer resection guide assembly for a distal total knee implant has an anchor member for anchoring into a resected distal surface of a femur, a block member including one or more cutting guide slots for guiding a cutting tool for making chamfer resections and a camming member. The camming member operably connects the block member and the anchor member and the position of the block member with respect to the anchor member is adjusted by operation of the camming member thus allowing adjustment of the position of the cutting guide slots with respect to the anchoring member.

  • Patent number: 8303596
    Abstract: The present invention relates to a device for positioning a jig at a structure using at least one fixing element comprising at least one adjusting element which can directly interact with or guide the at least one fixing element and which can interact with the jig, so that the relative position between the at least one fixing element and the jig can be adjusted by changing the position of the at least one adjusting element, as well as to a method for positioning a jig at a structure comprising two rotatable adjusting elements, wherein the resection plane of the jig can be moved along or in a first direction when the adjusting elements are moved in the same direction and wherein the resection plane is turned if the adjusting elements are moved in an opposite or different direction or only one adjusting element is moved.

  • Patent number: 8298238
    Abstract: Cutting guides, cutting tools, and soft tissue management techniques permit the use of pivoting guide surfaces to facilitate in controlling the sweep or arc of a cutting tool used in connection with resection and arthroplasty procedures. In accordance with one embodiment, a guide structure is provided with one or more guide pivot aperture(s) and one or more guide pivot reference surface(s) that mate with a bushing assembly controlling a cutting tool. The bushing assembly possesses a bushing reference plan which mates with the pivot reference surface(s) of the guide structure and a bushing pivot pin which mates with the guide pivot aperture(s) of the guide structure. In one embodiment, a bushing guide lumen is operably coupled to the guide structure for articulated and/or axial guidance of the cutting tool.
