    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 registration pointer for registering points of surfaces of bodily elements in computer-assisted surgery, comprising a handle for being manipulated by a pointer operator. A stem is connected to the handle and has a first and a second tip configurations each having a respective use relating to a registration of points on specified bodily elements. A detectable device is secured to the stem, and is adapted to be tracked in space for position and orientation by a sensing apparatus. A position of the tip configurations with respect to the detectable device is determinable such that a position of the tip configurations is calculable as a function of the position and orientation of the detectable device. The tip configurations are chosen to register points on given bodily elements as a function of the respective use, by recording a position of points of contact between the tip configurations and the given bodily element.

    摘要： A system for tracking a bone-altering tool in computer-assisted surgery, comprising a first trackable reference secured to a first bone, with a first frame of reference being associated with the first trackable reference. A bone-altering tool is securable to the first bone in a secured configuration. Sensors track the trackable reference for position and orientation. A position/orientation calculator is connected to the sensor device to calculate a position and orientation of the first frame of reference. An alteration parameter calculator is associated with the position/orientation calculator to determine a position and orientation of the bone-altering tool in the secured configuration as a function of the position and orientation of the first frame of reference and of the secured configuration. A method for tracking tools using the tracking of a bone is provided.

    摘要： There is described a method of manufacturing a device to be used with a computer-aided surgery system, a method of calibrating the device, and the device itself. After fabrication, the device is measured to obtain true parameters thereof. The true parameters are stored on a storage medium associated with the device and include measurement data of high precision relating to dimensions of the device as well as to relative positioning of a tracker on the device with respect to the device. The true parameters are entered into the system and when the tracker is located in the 3D environment, the device can then be located in the 3D environment with a high degree of precision using the true parameters.

    摘要： A method of determining a center of curvature of the spherical outer surface of an object using a computer system is provided. The method includes defining at least one contact region on the spherical outer surface in a plane substantially tangential to a circumference thereof and a first reference axis normal to said plane. Spatial coordinates of at least one of a first and a second geometric parameter are determined, the first geometric parameter including at least two points located on the spherical outer surface and the second geometric parameter including a second reference axis normal to the spherical outer surface. The center of curvature of the spherical outer surface is then calculated using the first reference axis and at least one of the first and second geometric parameters. An associated system and calibration device is also provided.
