摘要： A CAS system for measuring surgical parameters during hip replacement surgery comprises a first tracking reference in fixed relation with the pelvis to form a frame of reference. A registration tool is trackable. A sensor apparatus tracks the first tracking reference and the registration tool. A controller unit receives tracking data for the first trackable reference and the registration tool. The controller unit has a position and orientation calculator for calculating from the tracking data a position and orientation of the pelvic tracking reference to track the frame of reference, and of the registration tool to produce femoral models at a first and a second sequential operative steps. An alignment adjustor aligns the femoral models with the frame of reference. A surgical parameter calculator calculates surgical parameters as a function of the femoral models as aligned by the alignment adjustor.

摘要： A system for tracking a femoral frame of reference in computer-assisted surgery comprises a sensor unit. The sensor unit is adapted to be secured to the femur. The sensor unit comprises accelerometer and gyroscope sensors that produce orientation data. A processing unit receives gyroscope and accelerometer data. The processing unit comprises a gyroscope-data calculator to provide calculated acceleration data resulting from movements of the femur, an accelerometer-data calculator to calculate measured acceleration data resulting from movements of the femur, and an acceleration comparator to relate an orientation of the sensor unit to the femur to define a femoral frame of reference. The femoral frame of reference is defined from the comparison between the calculated and the measured acceleration data. A sensor orientation interface provides orientation data for the femur from a tracking of the femoral frame of reference. A method for tracking a femoral frame of reference is also provided.

摘要： A method for establishing an interaction between an operator and a monitor of a computer-assisted surgery system comprises tracking a tool manipulated by the operator for providing surgical data calculated from the position/orientation of the tool. A desired interaction is identified from the operator by tracking the tool reaching a specific position and/or a specific orientation. An interactive action is activated on a monitor as a function of the desired interaction, the interactive action being unrelated to said surgical data. A motion of the tool is converted to additional interactions related to said interactive action. A computer-assisted surgery system is also provided.

摘要： A hip resurfacing CAS system (200) for guiding an operator in altering a femoral head in computer-assisted surgery for subsequent implanting of a femoral head implant, comprises a trackable reference (202) on the femur. A registration tool (204) is trackable. A bone-altering tool (204) is associated with a resurfacing of the femoral head. A tracking apparatus (206) tracks the tools (202,204,206). A resurfacing processing unit (201) is connected to the tracking apparatus (206) so as to receive tracking data for the tools (202, 204, 206). The resurfacing processing unit (201) has a position/orientation calculator (212) to calculate from the tracking data a position and orientation of the trackable reference (202) to track the femoral frame of reference, and of the registration tool (204) and the bone-altering tool (204). A model generator (216) receives position and orientation data of the registration tool (204) to produce a model of the femoral head and neck with respect to the femoral frame of reference. A resurfacing evaluator (218) determines an evaluated bone resurfacing alteration as a function of a position and/or orientation of the bone-altering tool (204) with respect to the bone model of the femoral head and neck, and a tool geometry model, at least prior to resurfacing being performed.
