Medical robotic system providing an auxiliary view of articulatable instruments extending out of a distal end of an entry guide
A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations and displayed on a display screen from the perspective of a specified viewing point.
1. A medical system comprising:
an entry guide; a plurality of instruments extending through and out of a distal end of the entry guide, wherein the plurality of instruments includes an image capturing instrument; a plurality of sensors adapted to generate state information by sensing states of the plurality of instruments; a display; and a processor programmed to: use the state information to generate a computer model of the plurality of instruments, adjust a view of the computer model to a perspective of a first fixed viewing point which is different than a viewing point for an image presently capturable by the image capturing instrument, calculate a centroid of the plurality of instruments, and cause the centroid to be displayed on the display along with the adjusted view of the computer model so as to provide an indication of whether the entry guide needs to be repositioned.
2. The medical system according to claim 1 , wherein the image capturing device comprises a stereo camera; and wherein the display is a three-dimensional monitor for displaying a three-dimensional image of a surgical site that has been captured by the stereo camera.
