Abstract
Systems, circuits, and methods to mitigate effects of short-term power losses in medical systems are provided. An exemplary surgical system includes a fluidics subsystem, a surgical instrument subsystem that couples to a surgical instrument and a power supply subsystem coupled to the surgical instrument subsystem. The power supply subsystem includes a main power supply connectable to AC mains to generate a voltage, a power bus connected to the main power supply, an alternate power supply, and a circuit that monitors the voltage on the power bus for powering the surgical instrument subsystem. The circuit automatically connects the power bus to the alternate power supply when the voltage drops below a reference voltage due to a power loss from the main power supply.
Claims17
An ophthalmic surgical system comprising:
- a fluidics subsystem;
- a surgical instrument subsystem that couples to a surgical instrument, wherein the surgical instrument is coupled to the fluidics subsystem;
- and
- a power supply subsystem coupled to the surgical instrument subsystem, the power supply subsystem comprising:
- a main power supply connectable to AC mains to generate a voltage;
- a power bus connected to the main power supply;
- an alternate power supply;
- and
- a circuit that monitors the voltage on the power bus for powering the surgical instrument subsystem and automatically connects the power bus to the alternate power supply when the voltage drops below a reference voltage due to a power loss from the main power supply;
- a computing system configured to operate the surgical system based on inputs from a user;
- a battery-based back-up power supply configured to provide power to the computing system;
- wherein the computing system is configured to measure a duration of power loss and take mitigating actions in anticipation of the power loss lasting longer than power can be sustained to the surgical instrument subsystem by the power supply subsystem.
