Publication number: 20200197105Abstract: Systems and methods are disclosed that utilize a robotic device supporting and moving a cutting tool in at least three degrees of freedom. A control system commands the robotic device to control or constrain movement of the cutting tool. A first tracker is coupled to the robotic device and a second tracker is coupled to an anatomy. The second tracker includes three markers that generate optical signals and a non-optical sensor that generates non-optical signals. A navigation system with an optical sensor is in communication with the control system. The navigation system receives, with the optical sensor, the optical signals from one or more of the three markers and receives the non-optical signals from the non-optical sensor. The navigation system communicates position data indicative of a position of the anatomy to the control system to control cutting of the anatomy based on the received optical and non-optical signals.Type: ApplicationFiled: February 6, 2020Publication date: June 25, 2020Applicant: Stryker CorporationInventor: Chunwu Wu

Publication number: 20200197106Abstract: A method and system for automatic landmark registration and registration using trajectory information and shape sensing during an endoscopic procedure, such as bronchoscopy, are described herein. A segmentation centerline of airways of a lung may be generated based on a pre-operative computed tomography (CT) image of the lung. Landmarks may be automatically detected on the segmentation centerline corresponding to bifurcations in the airways of the lung. A location data point cloud of locations of a catheter through the airways of the lung during navigation may be generated. A bounding volume of the airways of the lung may be generated and a bounding volume centerline may be detected. Landmarks may be detected on the bounding volume centerline for the same bifurcations. Then, the two sets of landmarks may be mapped as part of registration. The trajectory information with shape sensing may be used to provide non-rigid or fine registration.Type: ApplicationFiled: March 2, 2020Publication date: June 25, 2020Applicant: Biosense Webster (Israel) Ltd.Inventors: Zvi Dekel, Akram Zoabi, Yaniv Ben Zrihem, Noam Rachli, Helen Volfson
