Aspects of a control system of a minimally invasive surgical apparatus
First Claim
1. A telerobotic system comprising:
- an input device having a handle, the handle movable so as to receive an input command;
a robotic arm having an end effector, the robotic arm moving the end effector in response to an actual slave command;
a master-slave control system coupling the input device to robotic arm, the control system simulating a movement of the robotic arm in response to the input command, deriving an actual command in response to the simulated robotic arm movement, and transmitting the actual command to the robotic arm so that the end effector moves.

Abstract
A surgical method and a control system can be used in a minimally invasive surgical apparatus. The method includes generating a desired surgical instrument movement command signal. It further includes comparing the desired surgical instrument movement command signal with at least one preset surgical instrument movement limitation. Should the desired surgical instrument command signal transgress the preset surgical instrument movement limitation, the desired surgical instrument movement command signal is restricted to yield a restricted surgical instrument movement command signal. A surgical instrument is then caused to move in response to the restricted surgical instrument movement command signal. The method further provides for haptic feedback on a master control in response to restriction of the desired surgical instrument movement command signal.

19. A method for moving a master-slave surgical instrument including:
-
generating an instrument movement input command signal by moving a master control with an input movement from a first location to a second location;
generating a kinematic simulated instrument movement corresponding to the input movement;
comparing the simulated instrument movement with at least one preset instrument movement limitation;
generating a restricted instrument movement command signal in response to the simulated instrument movement transgressing the preset instrument movement limitation;
moving the surgical instrument in response to the restricted instrument movement command signal; and
urging the master control away from transgressing the preset instrument limitation. - View Dependent Claims (20, 21, 22, 26, 27, 28)

29. A surgical apparatus control system including
a movable master control arranged to generate an instrument movement input command signal corresponding to a movement of the master control from a first location to a second location; -
a surgical instrument operatively coupled to the master control; and
one or more processor arranged to generate a kinematic simulated instrument movement, compare the simulated instrument movement with at least one preset instrument movement limitation, restrict the simulated instrument movement so as to yield a restricted instrument movement command signal in response to the simulated instrument movement transgressing the preset instrument movement limitation, the surgical instrument moving in response to the restricted instrument command signal, and generate a feedback signal against the master control corresponding to the simulated instrument movement transgressing the preset instrument movement limitation, the master control resisting the movement from the first location to the second location in response to the feedback signal.
