A multi-energy port splitter for a modular energy system includes an input port configured to couple to an energy output port of an energy module, a first energy output port configured to deliver energy supplied by the energy output port of the energy module, and at least a second energy output port configured to deliver the energy supplied by the energy output port of the energy module. An electronically controlled power switch configured to switch energy received at the input port to one of the first energy output port or the at least second energy output port. A controller is configured to couple to the energy module through a first communication bus. The controller is electrically coupled to the electronically controlled power switch through a power switch control line. A backplane including backplane communication interfaces is configured to receive a multi-energy port splitter and an energy module.

Modular energy system with multi-energy port splitter for multiple energy devices

Mitigating a user interface display function of a modular energy system includes receiving formatted video data at a video data converter circuit, providing differential video signaling data to the display from the video data converter circuit, providing a copy of the differential video signaling data to a processor, and determining that the differential video signaling data is changing over time. Mitigating erroneous outputs from an isolated interface includes receiving a state of a first switch of a first footswitch coupled to a first comparator and a reference voltage coupled to the first comparator, receiving the state of the first switch coupled to the first duplicate comparator and the reference voltage coupled to the first duplicate comparator, comparing the output of the first comparator with the output of the first duplicate comparator, and determining activation or deactivation of a surgical instrument coupled to the controller based on the comparison.

Modular energy system for use in a surgical environment

A method of delivering power to a load coupled to an energy module includes determining a power to be produced in a load, generating a signal, and selecting a first or second power amplifier circuit based on the power to be produced in the load. The power rating of the amplifier circuits is different. Another method includes generating a digital waveform having a predetermined wave shape and frequency, converting the digital waveform to an analog waveform, selecting a first power amplifier circuit or a second power amplifier circuit based on a predetermined power output to be produced by the first or second power amplifier circuit into a load coupled to an energy output port of the energy module, coupling the analog waveform to the selected first or second power amplifier circuit, and producing the predetermined power output into the load.

Method for energy delivery for modular energy system

A dual amplifier apparatus is disclosed. The apparatus includes an energy module having a controller and a first and second power amplifier circuit coupled to the controller. The first and second power amplifier circuits are configured to receive and amplify an input signal to generate a first output signal into a load coupled to the output of the first and second power amplifier circuit. A power rating of the first amplifier circuit is different from a power rating of the second amplifier circuit. The controller is configured to select the first or the second power amplifier circuit.

Modular energy system with dual amplifiers and techniques for updating parameters thereof

A modular energy system for use in a surgical environment includes a plurality of functional modules including at least an initial module, a functional module, and a terminal module. Each of the plurality of modules has a module control circuit, and a local data bus. An internal data bus is composed of a serial array of the local data busses of the modules. The local data bus may includes a communication switch, a first switch data path between the communication switch and the module control circuit, a second switch data path in communication with the communication switch, and a third switch data path in communication with the communication switch. The third switch data path of a module N is in communication with a second switch data path of a module N+1. The system further includes a termination unit in communication with the third data path of the terminal module.
