ELECTROSURGICAL INSTRUMENT AND ULTRASONIC SCALPEL Russian patent published in 2025 - IPC A61B17/3211 A61B18/12 A61B18/20 H02J7/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to an electrosurgical instrument and an ultrasonic scalpel. Electrosurgical instrument comprises an integrated battery, a control unit, first and second power consumption circuits. Power consumption of the second circuit in the operating state is greater than that of the first circuit in the operating state. When the electrosurgical instrument is not connected to an external power source, the control unit and the first power consumption circuit can be switched to connect the circuit to the integrated battery. Second power consumption circuit remains in the shutdown state when the electrosurgical instrument is not connected to the external power source. When the electrosurgical instrument is connected to the external power supply through the power connector, the first and second power consumption circuits are connected to the external power supply and are in an operative state. Ultrasonic scalpel comprises operational key, built-in battery, control unit, first and second power consumption circuits. Power consumption of the first circuit is lower than that of the second circuit. In an ultrasonic scalpel connected to an external power supply through a power connector, the first and second power consumption circuits are connected to the external power supply and are in an operating state.

EFFECT: electrosurgical instrument and ultrasonic scalpel are provided, which can check the device state parameters at low power consumption and without an external power source.
