Publication number: 20240081859Abstract: Surgical hub systems are disclosed. A surgical hub system comprises a surgical hub configured to communicably couple to a modular device comprising a sensor configured to detect data associated with the modular device and a device processor. The surgical hub comprises a hub processor, a hub memory coupled to the hub processor. The surgical hub system also comprises a distributed control system executable at least in part by each of the device processor and the hub processor.
