Abstract: A device and method for a trackable suction tool in surgical use. A trackable suction tool involves a tubular handle with a main tube and an entrance tube extending from the main tube, a flattened section of the main tube with a suction-regulating orifice, a tip coupled with the main tube distal end and a tracking mechanism coupled with a handle proximal end. A method of tracking position of a trackable suction device involves attaching a tip to a handle in one of a plurality of fixed positions, attaching a tracking mechanism to the handle in one of a plurality of fixed positions, calibrating the position of the tip with a positional tracking system using the tracking mechanism, positioning the tracking markers in view of the positional tracking system, and tracking a position of the distal end of the tip of the suction device.

Abstract: Methods and apparatuses for performing patient registration. 3D scan data from a 3D scanner, preoperative image data, first tracking data from a first tracking system, and second tracking data from a second tracking system are mapped to a common coordinate space. The 3D scan data and the first tracking data are mapped to each other using a transformation that is determined based on a calibration relating the 3D scan coordinate space and the tracking coordinate space. The 3D scan data and the preoperative image data are mapped to each other using a surface matching algorithm. The first tracking data and the second tracking data are mapped to each other based on tracking of the patient reference device.

Abstract: A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

Abstract: An apparatus and methods, operable with a medical navigation system, for calibrating a medical tool having a tip, involving a body configured to accommodate a plurality of tool dimensions and having a plurality of cooperating spring-loaded cams for accommodating a plurality of tool cross-sectional dimensions, a frame couple-able with the body and having at least one frame tracking marker coupled therewith, and a reference point feature coupled with the body, the reference point feature providing a known spatial reference point relative to the at least one frame tracking marker.

Abstract: A handheld scanner is provided for use in registering a patient for a medical procedure with a medical navigation system. The handheld scanner has a housing having a main body portion having a first end and a second end and a handle portion having a first end and a second end with the second end attached to the second end of the main body portion with a bridge portion. The handheld scanner further has a circuit board contained in the housing, a processor connected to the circuit board, a light emitter contained in the main body portion and connected to the circuit board, a light detector contained in the main body portion and connected to the circuit board, and a button connected to the circuit board and located on the second end of the handle portion. The button is engageable by a thumb of a hand holding the handle portion.
