    摘要: There is described a method and a system for generating a non-imaged plane view of an anatomical part for assisting a surgery. A model of the anatomical part is provided, comprising features and dimension parameters. A first plane view of the anatomical part is obtained. Features are identified in the first plane view. The dimension parameters are measured from the features identified. The model is displayed in the non-imaged plane view such that the model is dimensioned with the measured dimension parameters. A position and orientation of a surgical object is then tracked relative to the anatomical part while a user navigates said surgical object in space and a representation of the surgical object to be overlaid in register on at least one the first plane view and/or the non-imaged view is generated.

    摘要: A CAS system and method for measuring surgical parameters during hip replacement surgery to guide an operator in inserting a hip joint implant in a femur, comprising a first trackable reference in fixed relation with the pelvis and a registration tool. A sensor apparatus tracks the first trackable reference and the registration tool. A controller unit is connected to the sensor apparatus so as to receive tracking data for the first trackable reference and the registration tool. The controller unit has a position and orientation calculator to calculate from the tracking data a position and orientation of the pelvic trackable reference to track the pelvic frame of reference, and of the registration tool to produce a femoral frame of reference at two sequential operative steps. A reference orientation adjustor receives tracking data for the pelvic frame of reference, and the femoral frame of reference associated with the first trackable reference, to orient the femoral frame of reference in a reference orientation with respect to the pelvic frame of reference, and to produce a reference adjustment value as a function of the reference orientation. A surgical parameter calculator receives tracking data from the registration tool to calculate surgical parameters as a function of the reference adjustment value, the surgical parameters at the two sequential operative steps being related by the reference orientation.

    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 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.
