摘要： There is described a device for use with a position sensing system to register position and orientation in a reference-coordinate system, the device comprising a set of at least three base units removably and non-invasively attachable to a skin surface covering a bone, each of the base units having a reference marker attached thereto, the reference markers being one of passive and active devices recognized by the position sensing system and positioned and oriented in the reference coordinate system with respect to a fixed reference, the base units adapted to measure a distance between the skin surface and the bone in conjunction with an ultrasound component.

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 system for calculating a position and orientation of an acetabular cup in computer-assisted surgery comprises a first trackable reference secured to a pelvis, with a frame of reference being associated with the first trackable reference. A device is positionable between a femoral neck and the acetabulum of the pelvis in a known relation, the device having a second trackable reference. Sensors track the trackable references for position and orientation. A position/orientation calculator calculates a position and orientation of the frame of reference and of the device and for determining an orientation of the neck axis with respect to the frame of reference from the known relation at a desired position of the femur. An implant position/orientation calculator provides cup implanting information with respect to the orientation of said neck axis as a function of the tracking for position and orientation of at least the first trackable reference.
