ULTRASONIC SCALPEL, ELECTROSURGICAL INSTRUMENT AND METHOD OF THEIR POWER CONTROL Russian patent published in 2025 - IPC A61B17/32 

FIELD: medicine.

SUBSTANCE: ultrasonic scalpel comprises a portable component, a control module, an ultrasonic generator and an ultrasonic cutting head and additionally contains the following modules: load detection module configured to detect the load state of the ultrasonic cutting head, wherein the load detection module is electrically connected to the input of the control module; energy conversion module, the input side of which is electrically connected to the output of the control module and the output side of which is electrically connected to the ultrasonic generator; a control module configured to receive a detection signal from the load detection module, and when the activation button is pressed, the control module controls the energy conversion module to control the output power of the ultrasonic generator.

EFFECT: ultrasonic scalpel in accordance with its load state automatically adjusts the output power of the ultrasonic generator; at the same time there is no effect on the result of the operation, in the unloaded state the unnecessary amplitude of the cutting head is reduced, the service life of the scalpel is increased, and the cost of one-time use of the ultrasonic scalpel is reduced.
