Method for communicating between modules and devices in a modular surgical system

1. A method for controlling an output of an energy module of a modular energy system, the modular energy system comprising a header module, the energy module, and a secondary module communicably coupled together, the energy module configured to provide an output driving an energy modality deliverable by a surgical instrument connected thereto, the method comprising:

causing the energy module to provide the output driving the energy modality delivered by the surgical instrument;

sensing a parameter associated with the secondary module;

receiving the parameter as sensed by the secondary module at the energy module;

adjusting the output of the energy module from a first state to a second state according to the received parameter; and

segregating, by a firewall configuration in the header module, the energy module and the secondary module from external communications, wherein the header module, the secondary module, and the energy module are in a serial configuration, wherein the header module is connected to a module comprising one of the secondary module or the energy module via a primary communication interface, wherein another module comprising one of the secondary module or the energy module is serially connected to the module connected via the primary communication interface, wherein the module is different from the other module.

2. The method of claim 1 , wherein the parameter is communicated from the secondary module to the energy module via the header module.

3. The method of claim 1 , wherein the parameter is communicated directly from the secondary module to the energy module.

4. The method of claim 1 , wherein:

the header module comprises a first communications interface, capable of external communications with another header module of another modular system;

the energy module comprises a secondary communications interface;

the secondary module comprises a third communications interface; and

the first communications interface, the second communications interface, and the third communications interface are configured to engage each other to communicably link the header module, the energy module, and the secondary module as the header module, the energy module, and the secondary module are physically connected in a stacked configuration to form the modular energy system.

5. The method of claim 1 , wherein the header module, the energy module, and the secondary module are communicably connected via a Data Distribution Service communication protocol.

6. The method of claim 5 , wherein information transfer between the header module, the energy module, and the secondary module is managed by a second custom software layer.

7. The method of claim 1 , wherein:

the surgical instrument comprises a first surgical instrument;

the secondary module is configured to be connected to a second surgical instrument, the second surgical instrument configured to sense a surgical procedure parameter associated with use of the second surgical instrument; and

the parameter comprises the surgical procedure parameter.

8. The method of claim 7 , wherein adjusting the output of the energy module comprises adjusting a power level of the energy module from a first power level to a second power level according to the surgical procedure parameter.

9. The method of claim 1 , wherein the header module is configured to communicate with an external device.

10. The method of claim 9 , wherein the external device comprises a control tower.

11. The method of claim 10 , further comprising:

relaying, via the header module, communications received from the control tower to the energy module or to the secondary module.

12. The method of claim 1 , wherein the adjusting of the output of the energy module from the first state to the second state is further according to coordination of energy use between modules to prevent energy overload of the modular energy system.
