Controlling a surgical navigation system
First Claim
1. A method for controlling a surgical navigation system, the method including:
- using user gestures as touch-free system control inputs;
associating a detection unit for detecting the touch-free system control inputs made by a user with a surgical navigation system;
controlling the navigation system in accordance with the control inputs;
moving a medical instrument by the user, wherein predetermined movements of the instrument are detected and identified by the detection unit as user gestures;
carrying out an initiating user gesture that comprises drawing, with a tip of the medical instrument, a geometrical shape in a free three-dimensional working field of the user above or near a patient;
recognizing the geometrical shape by the navigation system as the initiating user gesture and defining a virtual volume surrounding the shape drawn in a sterile working field of the user; and
starting an interaction mode on the navigation system in which at least one further predetermined gestures made in the virtual volume is identified and recognized as a control input.

Abstract
Provided is a method for controlling a surgical navigation system. A detection unit for detecting system control inputs made by a user is associated with a surgical navigation system, the navigation system is controlled in accordance with the control inputs, and user gestures are used as said control inputs. A gesture or a initiating user gesture defines a virtual volume surrounding the initiating gesture'"'"'s limits, and further predetermined gestures made in the virtual volume are recognized as a control input. Also provided is a control system for a surgical navigation system. The navigation system is associated with a detection unit for detecting system control inputs made by a user, the navigation system is controlled in accordance with the control inputs, and the detection unit includes a gesture detection system for detecting user gestures.

12. A non-transitory computer-readable program storage medium storing a computer program for controlling a surgical navigation system, which, when running on a computer or loaded onto the computer, causes the computer to:
-
use user gestures as touch-free system control inputs; associate a detection unit for detecting the touch-free system control inputs made by a user with a surgical navigation system; control the navigation system in accordance with the control inputs; detect and identify, by the detection unit as user gestures, predetermined movements of the instrument when the instrument is moved by the user; recognize a geometrical shape by the navigation system as an initiating user gesture and define a virtual volume surrounding the shape drawn in a sterile working field of the user, where the initiating user gesture is carried out by drawing, with a tip of the medical instrument, the geometrical shape in a free three-dimensional working field of the user above or near a patient; and start an interaction mode on the navigation system in which at least one further predetermined gestures made in the virtual volume is identified and recognized as a control input.

13. A control system for a surgical navigation system, the control system comprising:
-
a detection unit associated with the navigation system and configured to detect touch-free system control inputs made by a user and the navigation system configured to be controlled in accordance with the control inputs, the detection unit comprising; a gesture detection system for detecting user gestures; and a camera system for visible light; and
/ora camera system for the invisible light spectrum; and
/ora tracking system in the form of a time-of-flight camera, a laser scanner, a heat tracking system or heat camera system or a magnetic or electromagnetic tracking system; wherein a medical instrument is moved by the user, wherein predetermined movements of the instrument are detected and identified by the detection unit as user gestures, wherein an initiating user gesture is carried out that comprises drawing, with the tip of the medical instrument, a geometrical shape in the free three-dimensional working field of the user above or near a patient, wherein the shape is recognized by the navigation system as the initiating user gesture and defines a virtual volume surrounding the shape drawing in a sterile working field of the user, and wherein an interaction mode is started on the navigation system in which at least one further predetermined gestures made in the virtual volume is identified and recognized as a control input. - View Dependent Claims (14, 15, 16, 17)
