  • Patent number: 8114083
    Abstract: Milling and drilling tools and soft tissue management techniques are provided for arthroplasty that facilitate intraoperative and postoperative efficacy and ease of use. In one embodiment, resiliently biased soft tissue protective sleeves surround a side cutting tool and are interposed along the longitudinal axis of the cutting tool, preferably adjacent each side of the bone. The soft tissue protective sleeves are biased to track along the contour of the side of the bone and prevent the cutting tool from being exposed to soft tissue during the resection. In another embodiment, a pilot drill is initially utilized to create an initial bore in the bone to be resected. The pilot drill preferably has an end cutting arrangement and a non-cutting removal channel that minimizes the tendency of the pilot drill bit to drift off-axis as the initial bore in the bone is created.

  • Publication number: 20110257654
    Abstract: The apparatus of the present invention includes a number of components including a guide body component, an extension block component, a rotating arm component, an extension rod component, and a tibial referencing component. The guide body component contacts the distal-most surface of the femur. Its location is based off of the posterior femoral condyles and the surface of the distal-most femoral resection or the unresected distal-most femoral surface. The rotating arm component is interconnected with the guide body and may rotate with respect thereto, thus allowing for the direct or indirect adjustment of the rotating alignment of cutting guides for resecting the distal femur. The rotating arm component carries arms with drill screw apertures which direct placement of drill holes in the femur which are used to attach a cutting guide to the femur.

  • Patent number: 8021368
    Abstract: A cutting tool is provided with an arcuate cutting blade that preferably engages a guide tool to create a curved resected surface during an arthorplasty procedure. In one embodiment, a depth of the cutting blade is sufficient to permit the simultaneous creation of resected surfaces on two bones that articulate, such as both the femor and the tibia for a given condyle, without the need to reposition the guide or the leg. In another embodiment, a cutting member has a generally rectangular cross-section along a longitudinal axis with a first and second surface having cutting teeth defined thereon and a third and fourth surface adapted to interface with a cutting guide positioned proximate the bone. In this embodiment, the cutting tool can resect the bone in two different directions without reorienting the cutting member.

  • Patent number: 7857814
    Abstract: A cutting tool for creating resected surfaces of bone during arthroplasty procedures has a single offset handle arm that presents a narrower effective width than a width of the cutting profile of the cutting tool along a longitudinal axis of the cutting profile. Preferably, the single offset handle arm creates a cutting tool with a generally L-shaped outline simultaneously accounting for soft tissue/incision geometry and bony geometry to accommodate both in facilitating ease of use and minimal displacement of soft tissue during cutting. The cutting tool can be snaked into position through an incision approximately the size of the width of the handle arm, instead of requiring an incision that is essentially the width of the cutting path of the cutting tool. In alternate embodiments, the cutting tool is a milling tool, a wireplasty cutting tool, a band saw or reciprocating cutting tool.

  • Patent number: 7815645
    Abstract: Methods and apparatus for performing arthoplasty utilizes a plurality of apertures created in a bone, each aperture having a cross section defined perpendicular to an axis of the aperture that intersects a plane of a resected surface to be created in the bone and also intersects a peripheral rim border that externally delineates the resected surface. A pin feature is inserted into each of the plurality of apertures and the resected surface is created by guiding a cutting tool along at least a line of contact of the pin features. An implant can then be attached to the resected surface.

  • Publication number: 20100174374
    Abstract: A dynamic spinal implant utilizes cartilage bearing graft material in dynamic disc replacement and/or facet arthroplasty. Methods and apparatus for dynamic spinal implants incorporate bulk articular graft tissues derived from donor joint sources in human (allograft or autograft) or non-human (xenograft) tissue. The donor joint is preferably prepared as a biological dynamic spinal implant with articular cartilage as a bearing interface between adjacent bone surfaces that naturally articulate with respect to one another.

  • Publication number: 20090138018
    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.

  • Publication number: 20090082773
    Abstract: A cutting tool to be utilized in the resection or removal of bone tissue from patients includes a handle that tensions a wire or cable-like cutting member with a small diameter between at least two features on the handle to present a thin cutting profile. The design of the cutting tool includes features that protect against soft tissue damage and minimize the incision size necessary to utilize the tool. Some embodiments feature details of the cutting tool that interface with a surgical cutting guide system. Other embodiments describe a cutting tool with a selectively changeable length of the cutting profile of the wire cutting member. In one embodiment, the wire cutting member of the cutting tool is energized by mechanical energy in the form of a unidirectional rotation of the cutting member, a mechanical vibration of the cutting member, or an oscillating movement of the wire cutting member.

  • Patent number: 7344541
    Abstract: Methods and apparatus for knee arthroplasty utilize components including an alignment device, a single medially or laterally located guidance device, and a cutting device for use in preparing the bones of a knee joint to receive knee arthroplasty implants. The alignment device is used to locate and orient the guidance device adjacent the medial or lateral side of a long bone of a knee joint. The cutting device is engaged with the guidance device and plunged across the end of the long bone to create a resected surface with respect to which a knee arthroplasty implant will be fixed. In one embodiment, the cutting tool guidance device extends less than about half way across the end of a long bone of a knee joint.

  • Patent number: 6695848
    Abstract: Methods and apparatus for femoral and tibial resection are provided. The apparatus of the present invention comprises a number of components including a positioning and drill guide, a cutting guide and a cutting apparatus. The drill guide is used to create holes in the medial and lateral sides of the femur that correspond to the fixation features of the cutting guide. The cutting guide is oriented and located by inserting fixation nubs connected to the cutting guide into the medial and lateral holes in the femur. The cutting guide can then be further affixed to the femur. The cutting apparatus can then be used with the cutting guide to resect the femur. A modified cutting guide can be used to position a conventional cutting block against a femur to be resected.
