Abstract

A surgical system comprising a surgical hub, a surgical instrument, a generator configured to energize an end effector; and a smoke evacuation system configured to remove smoke from a surgical site is disclosed. The surgical instrument comprises the end effector. A control command is passed directly from the surgical hub to the surgical instrument. The surgical instrument is configured to pass the control command received from the surgical hub to the generator and the smoke evacuation system in a daisy-chain manner.

First claim

What is claimed is:

1. A surgical system, comprising:
a surgical hub comprising a hub processor configured to provide a first signal;
a surgical instrument comprising an end effector, a sensor, and an instrument processor, wherein the instrument processor is to receive, from the surgical hub, the first signal;
an electrosurgical generator comprising a generator processor, wherein the electrosurgical generator is configured to energize the end effector, wherein the instrument processor is configured to communicate, to the electrosurgical generator, a second signal; and
a smoke evacuation system configured to remove smoke from a surgical site, wherein the generator processor is configured to communicate, to the smoke evacuation system, a third signal; wherein the surgical hub, the surgical instrument, the electrosurgical generator, and the smoke evacuator system are configured to communicate in a daisy-chain manner.

2. The surgical system of claim 1 , wherein the surgical instrument is configured to modify the second signal based on a parameter of the end effector detected by the sensor of the surgical instrument.

3. The surgical system of claim 2 , wherein the surgical instrument is configured to communicate the modified second signal to the electrosurgical generator.

4. The surgical system of claim 3 , wherein an operating parameter of the electrosurgical generator is controlled by the modified second signal.

5. The surgical system of claim 3 , wherein the electrosurgical generator is configured to alter the modified second signal with a second parameter detected by the electrosurgical generator.

6. The surgical system of claim 2 , wherein the surgical instrument is configured to communicate the modified second signal to the surgical hub, and wherein the surgical hub is configured to communicate the modified second signal to the electrosurgical generator.

7. The surgical system of claim 1 , wherein the sensor of the surgical instrument is configured to detect a first parameter of the end effector, wherein the instrument processor is configured to communicate the detected first parameter to the electrosurgical generator, and wherein the generator processor is configured to modify the first signal based on the first parameter.

8. The surgical system of claim 1 , wherein the surgical instrument sensor is configured to detect a first parameter of the end effector of the surgical instrument, wherein the instrument processor is configured to communicate the detected first parameter to the electrosurgical generator, wherein the electrosurgical generator detects a second parameter, and wherein the electrosurgical generator is configured to modify the third signal with the first parameter and the second parameter.

9. The surgical system of claim 1 , further comprising a display screen configured to display a live feed of a surgical site and a first operating parameter of the surgical instrument.

10. The surgical system of claim 9 , wherein the surgical instrument further comprises an instrument display configured to display a second operating parameter of the surgical instrument, and wherein the first operating parameter is the same as the second operating parameter.

11. The surgical system of claim 9 , wherein the surgical instrument further comprises an instrument display configured to display a second operating parameter of the surgical instrument, and wherein the first operating parameter is different than the second operating parameter.

12. The surgical system of claim 9 , wherein the display screen is further configured to display an operating parameter of the electrosurgical generator.

13. A surgical system, comprising:
a surgical hub comprising a hub processor configured to provide a first signal;
a surgical instrument comprising an end effector, a sensor, and an instrument processor, wherein the instrument processor is to receive, from the surgical hub, the first signal;
an electrosurgical generator comprising a generator processor, wherein the electrosurgical generator is to energize the end effector, wherein the instrument processor is configured to communicate, to the electrosurgical generator, a second signal; and
a smoke evacuation system configured to remove smoke from a surgical site, wherein the generator processor is configured to communicate, to the smoke evacuation system, a third signal.

14. The surgical system of claim 13 , wherein the first signal, the second signal, and the third signal are communicated in a daisy-chain manner.

15. A surgical system, comprising:
a surgical hub comprising a hub processor configured to provide a first signal;
a first surgical instrument comprising a first end effector and a first processor, wherein the first processor is to receive, from the surgical hub, the first signal;
a first electrosurgical generator comprising a first generator processor, wherein the first electrosurgical generator is to energize the first end effector, wherein the first processor of the first surgical instrument is to communicate, to the first electrosurgical generator, a second signal; and
a second surgical instrument, wherein the first generator processor is configured to communicate, to the second surgical instrument, a third signal;
wherein the surgical hub, the first surgical instrument, the first electrosurgical generator, and the second surgical instrument are configured to communicate in a daisy-chain manner.

16. The surgical system of claim 15 , wherein the first surgical instrument is configured to modify the second signal with a first parameter detected by the first surgical instrument.

17. The surgical system of claim 16 , wherein the first surgical instrument is configured to convey the modified second signal to the second surgical instrument.

18. The surgical system of claim 17 , wherein the second surgical instrument is configured to alter the modified second signal with a second parameter detected by the second surgical instrument, and wherein the second surgical instrument is configured to convey the modified second signal to the first surgical instrument.

19. The surgical system of claim 15 , wherein the first surgical instrument is configured to detect a first parameter, wherein the second surgical instrument is configured to detect a second parameter, wherein the second surgical instrument is configured to communicate the detected second parameter to the first surgical instrument, and wherein the first surgical instrument is configured to modify the second signal with the first parameter detected by the first surgical instrument and the second parameter detected by the second surgical instrument.

20. The surgical system of claim 15 , wherein the second surgical instrument comprises a smoke evacuation system configured to remove smoke from a surgical site.
