摘要： 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.

摘要： 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.
