Abstract: A humerus cutting assembly includes a guide frame having an attachment member adapted to be secured to a humerus adjacent to a humeral head. A cutting guide is releasably connected to the guide frame, the cutting guide configured to guide a tool in altering the humeral head. One or more inertial sensor units is on the cutting guide, the inertial sensor unit tracking an orientation of the cutting guide relative to the humerus based on the releasable connection between the cutting guide and the guide frame.

Abstract: A method for spine tracking in computer-assisted surgery, the method includes: obtaining, at a computer-assisted surgical system, at least one image of at least part of the spine and at least one surgical device; determining, at the computer-assisted surgical system, a three-dimensional position and orientation of the at least one surgical device relative to the spine from the at least one image to create a referential system; tracking, at the computer-assisted surgical system, the at least one surgical device altering a first vertebra of the spine for attachment of a spinal screw to the first vertebra, in the referential system; and tracking, at the computer-assisted surgical system, the spine in the referential system with a trackable reference attached to the spinal screw of the first vertebra.

Abstract: The biopsy device generally comprises: a cannula body having a longitudinal axis and a probing region extending along the longitudinal axis, the probing region having a sample receiving window defined therein for receiving a sample of a surrounding tissue when performing a biopsy; and a plurality of optical fibers mounted along an exterior portion of the cannula body, each of the plurality of optical fibers having a fiber end in the probing region of the cannula body, at least one of the plurality of optical fibers being adapted to illuminate the surrounding tissue with an optical signal generated by the at least one light generator and at least one of the plurality of optical fibers being adapted to detect an optical signal response with the at least one light detector, the optical signal response being caused by the propagation of the optical signal in the surrounding tissue.
