The Calibration body EM is used to calibrate a surgical endoscope which is tracked with Endoscope tracker EM. The location of the Calibration Body EM is referenced relative to the Endoscope tracker EM and allows Navigation Software NOVA AR to compute the optical parameters of the attached surgical endoscope. The Calibration body EM connects to the Hybrid Navigation Unit EM via an integrated cable.The Calibration body EM is provided non-sterile and is intended to be sterilized by the user.The Calibration body EM is reusable.
An assembly of devices intended to provide a physician with an electromagnetic (EM) tool for image registration and/or tracking of manual surgical instruments typically with respect to pre-acquired images (e.g., CT/MRI scan) or real-time data [e.g., ultrasound (US)] during surgery. It consists of a workstation with controls/display, a line-powered EM field generator, a tracking unit, instruments and trackers with sensors/localizers, and adhesive skin markers. It is used for multiple surgical procedures (e.g., ethmoidectomy, tumour resection, fibroid ablation, biopsy, drilling, vascular access) in various fields [e.g., ENT, craniomaxillofacial (CMF), laparoscopic, or orthopaedic surgery].
