Embodiment Construction

[0047] The present description provides a method for displaying the position of an endoscope within a patient. In one embodiment, the image of the endoscope used in endoscopic surgery is projected directly onto the patient's body, which allows the surgeon to clearly determine the position of the endoscope within the body. In another embodiment, the position of the endoscope within the patient's body is displayed as an image on a monitor along with images of the patient's internal organs, which allows the operator to easily manipulate the endoscope within the body.

[0048] In various embodiments, the methods of the present specification allow a surgeon to accurately determine the position of an endoscope within a patient during an endoscopic procedure, thereby significantly reducing endoscope navigation time. This method also allows the operator to correctly determine the distance between the tip of the endoscope and the patient's cecum during GI procedures.

Abstract

Systems and methods of tracking the position of an endoscope within a patient's body during an endoscopic procedure is disclosed. The devices and methods include determining a position of the endoscope within the patient in the endoscope's coordinate system, capturing in an image fiducial markers attached to the endoscope by an external optical tracker, transforming the captured fiducial markers from the endoscope's coordinate system to the optical tracker's coordinate system, projecting a virtual image of the endoscope on a model of the patient's organ, and projecting or displaying the combined image.
