ENT Ears, nose & throat; formally, otorhinolaryngology is a portable surgical navigation system developed to meet the requirements of sinus surgery in smaller hospitals. Image-guided software enables the surgeon to track pre-existing surgical instruments, integrate real-time endoscopic video images, and control the navigation system via a touch-screen monitor. The system is easy to set up. The patient's preoperative pre·op·er·a·tive adj. Preceding a surgical operation. preoperative preceding an operation. preoperative care the preparation of a patient before operation. CT scans are directly loaded into the system via a DICOM (medical, standard) DICOM - (From Digital Imaging and COmmunications in Medicine) A standard developed by ACR-NEMA (American College of Radiology - National Electrical Manufacturer's Association) for communications between medical imaging devices. network, or CD-ROM CD-ROM: see compact disc. CD-ROM in full compact disc read-only memory Type of computer storage medium that is read optically (e.g., by a laser). .A flexible headband and reference star with reflective markers is attached to the patient's head, and the registration is done with a special wireless Softouch[TM] pointer. The pointer identifies surface points on skin contact, thereby eliminating registration inaccuracies that may be caused by skin shift. The Kolibri ENT system then guides the surgeon through the procedure and provides continuous online information on instrument position and movement in multiple planes (sagittal sagittal /sag·it·tal/ (saj´i-t'l) 1. shaped like an arrow. 2. situated in the direction of the sagittal suture; said of an anteroposterior plane or section parallel to the median plane of the body. , axial, or coronal cor·o·nal adj. 1. Of or relating to a corona, especially of the head. 2. Of, relating to, or having the direction of the coronal suture or of the plane dividing the body into front and back portions. ). Additional features include a tool tip offset that allows the surgeon to virtually extend the tip of his/her instrument, to allow virtual navigation deep into the patient's sinuses. Existing surgical instruments can be integrated by attaching wireless adaptor clamps. Even the tip of extremely bent or curved instruments can easily be calibrated for navigation. In addition, surgeons have the option of saving intraoperative images on the system's CD-ROM for postoperative documentation. Circle 155 on Reader Service Card |
