Robotic surgical system with selective motion control decoupling
First Claim
1. A surgical system, comprising:
- an electromechanical tool including an instrument shaft and an end effector formed on the instrument shaft, wherein the end effector is configured to perform a plurality of surgical functions on tissue of a patient;
an electromechanical arm configured for movement with respect to multiple axes, wherein the electromechanical tool is configured to be mounted on, and move relative to, the electromechanical arm; and
a control system configured to control movement and surgical functions of the end effector according to at least two control states in response to actuation of a user interface device, wherein;
in a first control state, a movement of the user interface device in a first selected direction effects a corresponding movement of the end effector in the first selected direction; and
in a second control state, a movement of the user interface device in the first selected direction does not effect a corresponding movement of the end effector in the first selected direction and the end effector performs a first surgical function in response to receipt of a first surgical function input by the user interface device; and
the control system enters the second control state from the first control state in response to receipt of a first transition input by the user interface device.

Abstract
Robotic surgical systems are provided for control of an end effector in response to actuation of a user interface device based upon different control states. In each control state, selected movement directions of the user interface device are either coupled to or decoupled from corresponding movements directions of the end effector. Decoupled movement directions can be recoupled by positioning the user interface device within a range of where the user interface device and the end effector were decoupled. To assist with such recoupling, a graphical image estimating a position of the end effector that would be achieved, based upon a current position of the user interface device, if the decoupled movement direction was recoupled can be overlaid upon a current position of the end effector.

12. A method of controlling a surgical robot, the method comprising:
-
receiving, by a computing device, an actuation signal corresponding to actuation of a user interface device; generating, by the computing device, a plurality of command signals in response to receipt of the actuation signal according to a first control state and a second control state, the plurality of command signals configured to control a surgical robot comprising an electromechanical arm, an electromechanical tool mounted to the electromechanical arm including an instrument shaft, and an end effector formed on the instrument shaft configured to perform a plurality of surgical functions on tissue of a patient, wherein; in the first control state, a movement of the user interface device in a first selected direction affects a corresponding movement of the end effector in the first selected direction; in the second control state, a movement of the user interface device in the first selected direction does not affects a corresponding movement of the end effector in the first selected movement direction and the end effector is configured to perform a first surgical function in response to receipt of a first surgical function input by the user interface device; and entering, by the computing device, the second control state from the first control state in response to receipt of a first transition input by the user interface device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
