摘要： A computer assisted surgery system for conducting orthopedic surgery on a knee joint includes a condyle digitizer having a posterior condyle abutment surface defining a first plane and a distal condyle abutment surface defining a second plane perpendicular to the first plane, and a trackable member which is locatable and trackable in three dimensional space by the computer assisted surgery system to define at least orientation of the condyle digitizer in real time. A computer determines a most remote reference point of the femur of the knee joint lying within at least one of the first and second planes when the condyle digitizer is abutted against condyles of the femur such that the posterior condyle abutment surface abuts a posterior side of the condyles and the distal condyle abutment surface abuts a distal side of the condyles.

摘要： A tool for digitizing a mechanical axis of a tibia using a computer-assisted surgery system is described. The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween. The upper mounting end is releasably fastenable to an upper reference point on a tibial plateau and the lower mounting end includes a self-centering malleoli engaging mechanism having opposed caliper arms displaceable in a common plane relative to each other for clamping engagement with the medial and lateral malleoli of the ankle. At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod. The mechanical axis of the tibia is parallel to the alignment rod and extends between the upper and lower reference points when the tool is mounted on the tibia.

摘要： A method of determining a reference point on condyles of a femur uses a computer assisted surgery system having a digitizer with perpendicular first and second planar surfaces, the digitizer being locatable and trackable in three dimensional space by the computer assisted surgery system. A digitized plane is created using the digitizer, the digitized plane being a posterior plane and/or a distal plane of the condyles. The posterior plane and the distal plane are respectively defined by the first and second planar surfaces of the digitizer. A location of the reference point in the digitized plane is then determined using the computer assisted surgical system. The reference point is a most remote point of the femur within the digitized plane.

摘要： A surgical device adapted for use with an image guided surgical system to facilitate monitoring inter-dependently mobile bone elements. A rigidly connected multiple-point anchor assembly is releasably engageable to at least two inter-dependently mobile bone elements and immobilizes the bone elements such that no relative movement therebetween is possible, and a complex rigid body comprising the immobilized bone elements and the multiple-point anchor assembly is formed. A trackable member is fastened to the multiple-point anchor assembly and comprises a detectable element adapted to be located and tracked in three dimensional space by the image guided surgical system, thereby defining position and movement of the complex rigid body.

摘要： A drill guide assembly for a drilling tool having a chuck engaging a bit portion comprising a tip and a length extending from the chuck, the drill guide assembly comprising a first member, a second member and a trackable member. The first member is adapted to abut a workpiece surface and defines a central aperture therethrough adapted to receive the bit portion of the drilling tool. The second member is adapted to be axially displaced with respect to the first member and is axially biased therefrom, and defines a central aperture therethrough adapted to receive the bit portion of the drilling tool. The trackable member, fastened to the second member, comprises a detectable element adapted to be located and tracked in three dimensional space, thereby defining the position and movement of the second member and therefore that of the bit portion of the drilling tool.
