Abstract: There is described a system and a method for assisting a user manipulating an object during a surgery, the method comprising: tracking the object in a sterile field in which surgery is being performed at a location using a tracking device which generates tracking data; processing the tracking data using a processing device located outside the sterile field to generate position and orientation information related to the object; and sending the position and orientation information related to the object to a displaying device positioned in the sterile field adjacent to the location at which the surgery is being performed, for display to the user.

Abstract: A surface digitizing tool has a film of micro-sensor elements, with each micro-sensor element related in a network affected by a shape of the film. The film is flexible to conform to a shape of a selected surface of an object. A processing unit receives signals from the micro-sensor elements of the network. The processing unit has a model generator producing a model of the selected surface of the object from the signals of the network of resistive elements. A positioning frame aligns a position and orientation of a drilling tool with respect to a bone element.

Abstract: The present document describes a method for producing a knee joint treatment plan and/or surgery plan for a patient, the method comprising: obtaining 3D kinematic data of the knee joint in movement; determining, from the 3D kinematic data, scores characterizing the joint function of the patient, the one or more scores being relative to one or more criteria; and comparing the scores to data in a database which characterize a plurality of treatment plans and/or surgery plans to generate the list of one or more treatment plans and/or surgery plans which match the scores.

Abstract: The described method for determining at least orientation of a pelvic bone in space and for tracking movement of the pelvic bone using a computer assisted surgery (CAS) system includes removably attaching, in a non-invasive manner, at least one reference marker, in communication with the CAS system, to a skin surface covering the pelvic bone. Registering at least orientation readings of the reference marker is then performed with respect to a fixed reference in a reference coordinate system, following which at least an orientation of the pelvic bone in the reference coordinate system is determined using the orientation readings of the reference marker. These steps are repeated to update the orientation readings while tracking the pelvic bone in space.

Abstract: 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.
