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: 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.

Abstract: A high pressure valve includes a body on which is fixed an electromagnet, the shell of which has a radial discal part provided with a central hole connecting an internal opposite surface to an external surface. The body is provided with a cylindrical external centring surface and with a radial support surface. The shell is arranged on the body around the centring surface, the external discal surface being in surface contact against the support surface of the body. The coil of the electromagnet is arranged in the tubular space between the body and the shell itself closed by a closure ring. The liquid-tightness between the body and the shell is ensured by a gasket compressed by a wedging washer against the centring surface and against the internal discal surface. The shell is then immobilized on the body by the wedging washer.
