Embodiment Construction

[0066] refer to figure 1 , which shows the navigation system 20 . Navigation system 20 is shown in a surgical setting, for example, in an operating room of a medical institution. Navigation system 20 is configured to track the movement of various objects within the operating room. Such targets include, for example, surgical instrument 22, patient's femur F, and patient's tibia T. The navigation system 20 tracks these objects for the purpose of displaying their relative positions and orientations to the surgeon and, in some cases, to control or limit the movement of the surgical instruments 22 relative to predefined paths or anatomical boundaries.

[0067] Navigation system 20 includes a computer cart assembly 24 housing a navigation computer 26 . The navigation interface is in operative communication with the navigation computer 26 . The navigation interface includes a first display 28 adapted to be outside the sterile field and a second display 29 adapted to be within the...

Abstract

Navigation systems and methods for tracking objects moving in space. A navigation system and method employs a tracker having a light emitter for indicating when the line of sight between a tracking element and a sensor on the tracker is obstructed or other errors. Another navigation system and method instructs the user how to position the tracker relative to the target to reduce line of sight problems during surgery.

Description

[0001] related application [0002] This application claims priority to and benefit of U.S. Provisional Patent Application No. 61 / 753,219, filed January 16, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure generally relates to navigation systems and methods for indicating and reducing line-of-sight errors when tracking one or more objects. Background technique [0004] The navigation system helps the user locate the target. For example, navigation systems are used in industrial, aerospace, defense and medical applications. In the medical field, navigation systems assist a surgeon in placing surgical instruments relative to a patient's anatomy. Surgical procedures using navigation systems include neurosurgery and orthopedics. The instruments and anatomical parts are tracked together with their relative motion displayed on the monitor. [0005] Navigation systems may employ light signals, sound waves, magnetic...
