Embodiment Construction

[0034] Various embodiments will be described in the following description. For purposes of illustration, specific configurations and details are set forth to provide a thorough understanding of the embodiments. It will also be apparent, however, to one skilled in the art that the embodiments may be practiced without these specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the described embodiments.

[0035] In many of the system and method embodiments described herein, the shape of the endoscope and the orientation of the distal end of the endoscope are tracked and displayed to assist the operator of the endoscope. In many embodiments, the display provides a visual indication of how much the distal end of the endoscope has twisted and tilted during advancement. Such a display not only helps the endoscope operator overcome spatial disorientation, but also helps the endoscope operator accurately straighten the endoscope.

Abstract

Systems and methods for tracking shape and orientation of an endoscope employ motion tracking sensors to track locations on the endoscope for use in determining real time shape and distal end orientation for display during navigation of the endoscope. An example system includes sensor units distributed along the endoscope and a control unit. The sensor units track motion of the endoscope locations and transmit resulting tracking data to a control unit. The control unit processes the tracking data to determine shape of the endoscope and orientation of the distal end of the endoscope. The control unit generates output to a display unit that causes the display unit to display one or more representations indicative of the shape of the endoscope and orientation of the distal end of the endoscope for reference by an endoscope operator during an endoscopic procedure.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of U.S. Provisional Patent Application No. 61 / 936,037, filed February 5, 2014, entitled "THREE DIMENSIONAL COMPASSASSASSED NAVIGATION TO AUGMENT ENDO-LAPAROSCOPY," the entire contents of which are incorporated herein by reference for all purposes. Background technique [0003] Endoscopy is used in a variety of patient examination procedures. For example, endoscopes are used to view the gastrointestinal tract (GI tract), respiratory tract, bile ducts, ear, urethra, female reproductive system, and normally closed body cavities. [0004] In some applications, it may be difficult to properly maneuver the endoscope during insertion. For example, colonoscopy is one of the most frequently performed outpatient tests. However, colonoscopy is also one of the most technically demanding endoscopies due to the possibility of unpredictable wrapping of the endoscope during insertion du...
