1. A medical system comprising:
- an entry guide;
a first articulatable instrument controllably extending out of a distal end of the entry guide, the first articulatable instrument having a most proximal joint and a most distal joint, the most distal joint disposed beyond the distal end the entry guide;
a display screen; and
a processor programmed to receive information of states of the entry guide and the first articulatable instrument, generate a view by including a graphical representation of the most distal joint of the first articulatable instrument and a graphical representation of a spatial boundary for the first articulatable instrument, the spatial boundary being a function of a position of the most distal joint relative to the distal end of the entry guide, and the graphical representation being positioned in the view by using the received information and by using forward kinematics of the entry guide and the first articulatable instrument, and display the view on the display screen.

Abstract
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 are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.

18. A method for repositioning an entry guide to increase an available range of motion of at least one of a plurality of articulatable instruments extending out of a distal end of the entry guide, wherein each of the plurality of articulatable instruments has a plurality of joints including a most distal joint, and wherein an available range of motion of each of the plurality of articulatable instruments is a function of a relative position of the most distal joint of the articulatable instrument to the distal end of the entry guide, the method comprising:
-
determining positions of the entry guide, the most distal joint of each of the plurality of articulatable instruments, and the available range of motion of each of the plurality of articulatable instruments; displaying graphical representations of the most distal joint and the available range of motion for each of the plurality of articulatable instruments according to their respectively determined positions on a display screen; and moving the entry guide according to operator manipulation of an input device so as to increase the available range of motion of at least one of the plurality of articulatable instruments while the operator is viewing the display screen and while the most distal joints of the plurality of articulatable instruments are being controllably held in place. - View Dependent Claims (19, 20)
