|20130274778||PATIENT SPECIFIC SURGICAL GUIDE - A patient specific instrument (PSI) surgical guide and method for producing same is described. The method includes: obtaining imagery of at least a portion of a patient, and determining one or more surgical targets in the tissue; planning at least a trajectory of the surgical procedure based on a determined surgical target within the tissue; performing segmentation of the imagery; creating a three-dimensional model of the PSI surgical guide, the PSI surgical guide being customized in size and shape and configured to fit on the specific patient. The PSI surgical guide is then produced to correspond to the modeled PSI surgical guide. The PSI surgical guide has a guide element positioned and oriented to guide a surgical implement along the planned trajectory toward the determined surgical target in the tissue.||10-17-2013|
|20130231672||METHOD AND SYSTEM FOR TRACKING OBJECTS IN COMPUTER-ASSISTED SURGERY - A computer-assisted surgery system comprises instruments adapted to be used to perform tasks related to surgery. A reference device is in a fixed relation to a bone. A rotating magnet creates a magnetic field plane, the rotating magnet being connected to one of the instrument and the reference device. A magnetometer on the other of the instrument and the reference device produces signals as a function of at least its orientation relative to the magnetic field plane. A processing unit tracks said orientation of the instrument relative to the bone using said signals from the magnetometer subjected to the magnetic field plane.||09-05-2013|
|20130165947||CONNECTION METHOD FOR MEMS NAVIGATION UNIT FOR COMPUTER-ASSISTED SURGERY - A computer-assisted surgery (CAS) navigation assembly comprises a micro-electromechanical sensor (MEMS) navigation unit having one or more MEMS to provide at least orientation data. A support receives the MEMS navigation unit therein, the support being adapted to be mounted on the instrument in a fixed orientation relative to established navigated features of the instrument. At least two mating ball-in-socket features are disposed between the MEMS navigation unit and the support at opposed ends thereof for releasably engaging the MEMS navigation unit in precise orientational alignment within the receptacle, the at least two mating ball-in-socket features comprising catches aligned along an axis extending between the opposed ends, at least one of the catches being a biased catch. A method of connecting a MEMS navigation unit with a mating support fixed to a CAS instrument navigated by the CAS system is also provided.||06-27-2013|
