Publication number: 20240000494Abstract: Electrosurgical generator and method for outputting a high-frequency alternating voltage to an electrosurgical instrument, including an inverter that generates a high-frequency alternating voltage having variable frequency and amplitude which is fed to an output socket for the electrosurgical instrument. Ahe inverter is a multi-level inverter controlled by a reference signal defining shape of the generated HF alternating voltage, the reference signal being defined by a datagram including a finite series of sequenced amplitude and frequency data vectors for a defined number of periods. By such datagrams including descriptive data for the desired HF sinusoidal curve, data amount and bandwidth required can be reduced. Thereby a variety of modes can be described using a minimum of data which can be as low as just a few dozen bytes long. This allows for efficient control even of complex modes.Type: ApplicationFiled: June 28, 2023Publication date: January 4, 2024Applicant: OLYMPUS WINTER & IBE GMBHInventors: Fabian JANICH, Jelle DIJKSTRA, Raphael BEHRENDT

Publication number: 20230210578Abstract: 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.Type: ApplicationFiled: December 7, 2022Publication date: July 6, 2023Applicant: OLYMPUS WINTER & IBE GMBHInventors: Fabian JANICH, Jens KRÜGER, Daniel RAMIN, Frank BREITSPRECHER

Patent number: 11650611Abstract: An electrosurgical generator with a high-voltage power supply that supplies a DC output voltage receives the DC output voltage of the high-voltage power supply and generates a high-frequency AC output voltage. When generator is operating, a control unit receives signals from an AC output voltage measuring unit and current measuring unit. The control unit limits an increase of DC output voltage of the high-voltage power supply as soon one predefined maximum value is reached or exceeded. When the generator is operating, the control unit configured to receive signals from a DC output voltage measuring unit that represent a respective current value of the DC output voltage, and to compare a respective current value of DC output voltage with a predefined minimum value for DC output voltage, and to cause the DC output voltage of the high-voltage power supply to increase as soon as it falls below the predefined minimum value.Type: GrantFiled: March 29, 2021Date of Patent: May 16, 2023Assignee: OLYMPUS WINTER & IBE GMBHInventors: Fabian Janich, Jelle Dijkstra, Frank Breitsprecher
