Abstract

A method for controlling a plurality of surgical devices includes: receiving a foot pedal signal indicating a foot pedal activation of a first foot pedal of a plurality of foot pedals; generating a control signal based on the foot pedal signal, wherein: if the foot pedal signal indicates that only the first foot pedal is pressed, then generating the control signal to cause a generator to activate a first surgical device associated with the first foot pedal; if the foot pedal signal indicates that the first foot pedal remains pressed and a second foot pedal is newly pressed, then generating the control signal to cause the generator to: maintain activation of the first surgical device associated with the first foot pedal; and not activate a second surgical device associated with the second foot pedal; and outputting the control signal to the generator.

First claim

That which is claimed is:

1. A method for controlling a plurality of surgical devices, the method comprising:
receiving a foot pedal signal to activate a first surgical device associated with a first foot pedal based on a pressing of the first foot pedal, the foot pedal signal indicating a foot pedal activation of the first foot pedal of a plurality of foot pedals;
generating a control signal based on the foot pedal signal, wherein:
if the foot pedal signal indicates that only the first foot pedal is pressed, then generating the control signal to cause a generator to activate the first surgical device;
if the foot pedal signal indicates that the first foot pedal remains pressed and a second foot pedal is newly pressed to transmit a second foot pedal signal to activate a second surgical device associated with the second foot pedal, the second foot pedal signal indicating a second foot pedal activation of the second foot pedal, then generating the control signal to cause the generator to:
maintain activation of the first surgical device associated with the first foot pedal; and
not activate the second surgical device; and

if the foot pedal signal indicates that the first foot pedal is released while the second foot pedal remains pressed, then generating the control signal to cause the generator to:
deactivate the first surgical device associated with the first foot pedal, and
not activate the second surgical device associated with the second foot pedal; and

outputting the control signal to the generator.

2. The method of claim 1 , wherein if the foot pedal signal indicates that the first foot pedal is the only foot pedal of the plurality of foot pedals pressed, then generating the control signal to cause the generator to maintain activation of the first surgical device associated with the first foot pedal.

3. The method of claim 1 , wherein if the foot pedal signal indicates that the pressed first foot pedal is released, then generating the control signal to cause the generator to deactivate the first surgical device associated with the first foot pedal.

4. The method of claim 1 , wherein if the foot pedal signal indicates that the second foot pedal remains pressed while the first foot pedal remains pressed, then generating the control signal to cause the generator to maintain activation of the first surgical device associated with the first foot pedal and to not activate the second surgical device associated with the second foot pedal.

5. The method of claim 1 , wherein if the foot pedal signal indicates that the first foot pedal is pressed, the second foot pedal is pressed while the first foot pedal remains pressed, and the second foot pedal is released while the first foot pedal remains pressed, then generating the control signal to cause the generator to maintain activation of the first surgical device associated with the first foot pedal.

6. The method of claim 1 , wherein if the foot pedal signal indicates that the pressed first foot pedal is released substantially simultaneously as the second foot pedal is pressed, then generating the control signal to cause the generator to deactivate the first surgical device associated with the first foot pedal.

7. The method of claim 1 , wherein determining the control signal based on the foot pedal signal comprises utilising a state machine, the state machine comprising a plurality of states, wherein:
a first state corresponds to no foot pedals active;
a second state corresponds to a single foot pedal active;
a third state corresponds to multiple foot pedals active; and
a fourth state corresponds to an invalid combination of foot pedals active.

8. The method of claim 7 , wherein the state machine transitions from the first state to the second state when the foot pedal signal indicates that the first foot pedal is pressed.

9. The method of claim 7 , wherein the state machine transitions from the second state to the third state when the foot pedal signal indicates that the first foot pedal remains pressed and the second foot pedal is newly pressed.

10. The method of claim 7 , wherein the state machine transitions from the third state to the fourth state when the foot pedal signal indicates that the first foot pedal is inactive and the second foot pedal remains pressed.

11. The method of claim 7 , wherein the state machine transitions from the fourth state to the first state when the foot pedal signal indicates that no foot pedal is pressed.

12. The method of claim 1 , further comprising transmitting an audio signal based on the generated control signal and outputting audio feedback based on the audio signal.

13. The method of claim 1 , wherein at least one proximity sensor is coupled to the plurality of foot pedals, the proximity sensor communicatively coupled to a processor and configured to detect the presence of an object proximate to the plurality of foot pedals; the processor configured to:
receive a sensor signal from the proximity sensor;
generate an error feedback signal based on the sensor signal, wherein:
if the sensor signal indicates that the first foot pedal is pressed and the proximity sensor coupled to the first foot pedal does not detect the presence of the object, then generating the error feedback signal to provide feedback to a user indicating the first foot pedal is inadvertently pressed; and

output the error feedback signal to a feedback device.

14. The method of claim 13 , wherein the feedback device is configured to output at least one of audio feedback, visual feedback, or tactile feedback.

15. A system comprising:
a plurality of foot pedals;
at least one generator; and
at least one processor communicatively coupled to the plurality of foot pedals and the at least one generator, the at least one processor configured to:
receive a foot pedal signal to activate a first surgical device associated with a first foot pedal based on a pressing of the first foot pedal, the foot pedal signal indicating a foot pedal activation of the first foot pedal of the plurality of foot pedals;
generate a control signal based on the foot pedal signal, wherein:
if the foot pedal signal indicates that only the first foot pedal is pressed, then generating the control signal to cause the at least one generator to activate the first surgical device;
if the foot pedal signal indicates that the first foot pedal remains pressed and a second foot pedal is newly pressed to transmit a second foot pedal signal to activate a second surgical device associated with the second foot pedal, the second foot pedal signal indicating a second foot pedal activation of the second foot pedal, then generating the control signal to cause the at least one generator to:
maintain activation of the first surgical device associated with the first foot pedal; and
not activate the second surgical device; and

if the foot pedal signal indicates that the first foot pedal is released while the second foot pedal remains pressed, then generating the control signal to cause the at least one generator to:
deactivate the first surgical device associated with the first foot pedal; and
not activate the second surgical device associated with the second foot pedal; and

outputting the control signal to the at least one generator.

16. The system of claim 15 , wherein if the foot pedal signal indicates that the first foot pedal is the only foot pedal of the plurality of foot pedals pressed, then generating the control signal to cause the generator to maintain activation of the first surgical device associated with the first foot pedal.
