摘要： Systems and methods for femoral medial condyle spherical center identification and tracking are described herein. Once the spherical center of the medial condyle is identified, the spherical center is tracked using a pin or internal reference. The spherical center may be used to provide a key kinematic motion reference, such as when the medial condyle is adjusted during a surgical procedure. The tracking may be used to provide optical tracking, inertial tracking, or other tracking. In contrast with surface-mounted optical trackers, the spherical center tracking is not lost during resection (e.g., removal) of a bone surface. Tracking the medial condyle spherical center may reduce or eliminate the need for a surface-mounted optical tracker or preoperative 3 -D modeling or of the joint.

摘要： A method for measuring the real hot-spot temperature in an electric apparatus containing an oil, such as an electric power transformer. The electric apparatus is operated under predetermined and modifiable operating conditions. This method comprises the use of one or several chemical compounds or tracers present and soluble in the oil. Each tracer may transform, at a given temperature, in order to form a residue, such as a soluble gas. From the presence of the residue in the oil, the operator will be able to determine under which predetermined operating condition the hot-spot has been reached and to deduce the hot-spot for a given condition. Among different used compounds, there are diazoic compounds, carbonyl metals, colorants, pigments, liquid crystals and albumins. The method also allows to check the quality of the apparatus on the market and to estimate its life span.

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 positioning device assembly for positioning a tool guide block for use in an orthopedic surgery on a bone element includes a positioning device having a block body with a reference surface adapted to abut the bone element, and first and second adjustment mechanisms that are independently operable. The first adjustment mechanism permits rotation of a tool guide block about a medial-lateral extending axis such as to provide flexion-extension angle adjustment and the second adjustment mechanism permits rotation of a tool guide block about an anterior-posterior extending axis such as to provide varus-valgus angle adjustment. The second adjustment mechanism includes both a coarse and a fine adjustment mechanism integral therewith. A tool guide block assembly mounted to the positioning device, the tool guide block assembly including a platform portion which is engaged to the block body of the positioning device and the tool guide block which is releasably engaged with the platform.
