What changed
USPTO granted patent US12599426B2 to Olympus Winter & Ibe GmbH for an electrosurgical generator with a switchable measurement monitoring system. The system allows the generator to toggle between multiple configurations with different measurement ranges during operation, enabling reliable measurement at high amplitudes while maintaining accuracy at low amplitudes. The patent covers 17 claims and was filed December 7, 2022.
This patent grant establishes enforceable intellectual property rights for the assignee in the United States. Medical device manufacturers developing electrosurgical equipment should monitor this IP landscape to assess potential licensing needs or design-around considerations.

Electrosurgical generator having an extended measurement range

Abstract
An electrosurgical generator for supplying power, including an inverter for high voltage, which is led to an output to the connector of an electrosurgical instrument, a measurement system with at least one measurement monitor for a physical parameter at the output or at the electrosurgical instrument, and an operation controller which controls the inverter on the basis of at least one predefined operating sequence. The measurement monitor for the physical parameter is switchable between a plurality of different configurations which differ in the measurement range. The operation controller interacts with the measurement system so one of the different configurations of the measurement monitor is switched in each case, under control by the operating sequence. By switching the configuration, the suitable measurement range is always set during operation. Apparently contrariwise requirements in relation to a reliable measurement even at high amplitudes are linked with great measurement accuracy even at low amplitudes.
