Visual force feedback in a minimally invasive surgical procedure
First Claim
Patent Images
1. A method of providing a visual representation of force information in a robotic surgical system, the method comprising:
- displaying a first image of a tool on a display screen, wherein the first image shows an actual position of the tool; and
displaying a second image of the tool on the display screen such that an offset between the displayed first and second images of the tool provides a visual indication of a force being applied against the tool.

Abstract
Methods of and a system for providing a visual representation of force information in a robotic surgical system. A real position of a surgical end effector is determined. A projected position of the surgical end effector if no force were applied against the end effector is also determined. Images representing the real and projected positions are output superimposed on a display. The offset between the two images provides a visual indication of a force applied to the end effector or to the kinematic chain that supports the end effector. In addition, tissue deformation information is determined and displayed.

13. A system of providing a visual representation of force information in a robotic system, the system comprising:
-
an image input for capturing an image of an end effector while a force is applied to the end effector; a display coupled to the image input so as to present an actual position of the end effector under the applied force; and a processor coupled to the display, the processor generating a second image representing a projected position of the end effector offset from the first position so as to visually indicate the force, the processor transmitting the second image to the display so that the second image is superimposed with the first image.

14. A method of providing a visual representation of tissue deformation in a robotic surgical system, the method comprising:
-
sensing a force which is being applied against a tissue so as to cause deformation of the tissue; determining by a processor device information indicative of the deformation of the tissue by using the sensed force; and displaying an image of the tissue and the information indicative of the deformation of the tissue superimposed over the image of the tissue on a display screen. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
