FIELD: medicine.

SUBSTANCE: invention discloses a method and a system for controlling temperature of an ultrasonic scalpel blade based on a temperature distribution function model. System includes an ultrasonic scalpel blade and a transducer, which are connected to each other and connected to a generator through a cable. When the ultrasonic scalpel blade is in operation, the actual temperature of the blade is distributed along the one-dimensional space of the blade. Temperature distribution on the blade is determined by a set of real-time feedback parameters, parameters of the physical structure characteristic and parameters of the blade environment. Each temperature distribution corresponds to solving the temperature distribution function, and this function can be approximated by a machine algorithm. When the ultrasonic scalpel blade is in operation, the real-time temperature distribution on the blade can be estimated by inputting into the machine learning algorithm such parameters as the real-time resonance frequency, voltage, current, impedance, power, shape and environmental parameters of the blade.

EFFECT: high accuracy and efficiency of controlling temperature of an ultrasonic scalpel blade.
