Abstract
A surgical input device configured to enable manual user input to a remote computing system is described. In one example, the surgical input device comprises an interface configured to be attachable to a surgical object such as a patient bone. The surgical input device further comprises a manually operable input wheel infinitely rotatable relative to the interface. The input wheel defines an optically detectable wheel marking. In some variants, the surgical input device or surgical object may comprise one or more tracking elements and may thus function as a surgical tracker.
Claims19
A surgical input device attachable or attached to a surgical object and configured to enable manual user input to a remote computing system, the surgical input device comprising:
- a manually operable input wheel configured to be rotated, wherein the input wheel defines an optically detectable wheel marking;
- a manually operable input button movable between a first position and at least one second position;
- an optically detectable button-related marking;
- and
- an occlusion element configured to cover a portion of a rotational trajectory of the wheel marking,
- wherein a transition of the input button between the first position and the at least one second position is optically detectable in that the transition changes an optical visibility of the button-related marking.
A method for determining a manual user input at a surgical input device to a remote computing system, wherein the surgical input device is attached to a surgical object and comprises a manually operable input wheel that is rotatable relative to the surgical object, wherein the input wheel defines an optically detectable wheel marking configured to be detectable by an optical camera, and wherein the surgical input device further comprises a manually operable input button that is movable between a first position and at least one second position, the method being implemented by at least one processor and comprising
- receiving first image data representative of the wheel marking;
- determining, based on the first image data, the wheel marking;
- determining a first user input associated with the wheel marking;
- determining, based on the first image data or based on second image data, a transition of the input button between the first position and the at least one second position;
- and
- determining the first or a second user input associated with the determined transition.
A computer program product, comprising instructions stored on at least one non-transitory computer readable medium that, when executed on at least one processor, cause the at least one processor to carry out a method for determining a manual user input at a surgical input device to a remote computing system, wherein the surgical input device is attached to a surgical object and comprises a manually operable input wheel that is rotatable relative to the surgical object, wherein the input wheel defines an optically detectable wheel marking configured to be detectable by an optical camera, and wherein the surgical input device further comprises a manually operable input button that is movable between a first position and at least one second position, the method comprising
- receiving first image data representative of the wheel marking;
- determining, based on the first image data, the wheel marking;
- determining a first user input associated with the wheel marking;
- determining, based on the first image data or based on second image data, a transition of the input button between the first position and the at least one second position;
- and
- determining the first or a second user input associated with the determined transition.
