Cooperative minimally invasive telesurgical system
First Claim
1. A medical system comprising:
- a medical instrument;
a first input device movable by an instructor;
a second input device movable by a student;
a controller configured to command movement of the medical instrument in response to movements of the first and second input devices according to relative percentages selected by the instructor and configured to command a resistance to be applied against movement of the second input device such that the resistance is indicative of a difference between the movements of the first and second input devices.

Abstract
Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.

5. A method for jointly controlling a medical instrument by an instructor and a student for training purposes, the method comprising:
-
detecting movement of a first input device by an instructor; detecting movement of a second input device by a student; commanding movement of the medical instrument in response to the detected movements of first and second input devices according to relative percentages selected by the instructor; and commanding a resistance to be applied against movement of the second input device such that the resistance is indicative of a difference between the movements of the first and second input devices.
