Abstract

Landmark directional guidance is provided to an operator of an endoscopic device by displaying graphical representations of vectors adjacent a current image captured by an image capturing device disposed at a tip of the endoscopic device and being displayed at the time on a display screen, wherein the graphical representations of the vectors point in directions that the endoscope tip is to be steered in order to move towards associated landmarks such as anatomic structures. Navigation guidance is provided to the operator by determining a current position and shape of the endoscope relative to a reference frame, generating an endoscope computer model according to the determined position and shape, and displaying the endoscope computer model along with a patient computer model referenced to the reference frame so as to be viewable by the operator while steering the endoscope.

Description

Technical field

[0001] The present invention relates generally to a steerable endoscope, and in particular to a method for providing visual guidance for manipulating the end of an endoscopic device to one or more landmarks and assisting an operator in endoscopic navigation And system. Background technique

[0002] Minimally invasive surgery procedures are known to provide more advantages than traditional open surgery, including less pain, shorter hospital stay, faster return to normal activities, less scars, shorter recovery time, and less tissue damage. In order to perform these procedures, an entrance into the patient's body must be created through an incision or a natural body hole. Robots and manual minimally invasive surgery equipment can be used.

[0003] An example of a minimally invasive surgical robotic system is Intuitive Surgical (Intuitive Surgical, Inc.) da Vinci of Sunnyvale, California. Surgical system. da Vinci The surgical system has several robotic arms that ...
