Automatic judgment method and system for ultrasonic ablation balloon adherence

The invention discloses an automatic judgment method and system for wall attachment of an ultrasonic ablation balloon. The method comprises the following steps: setting related working parameters; after the balloon moves to a target ablation area, normal saline is injected; detecting the pressure in the balloon and the resistance value outside the balloon, and feeding back to the control system; and judging whether the balloon adheres to the blood vessel well or not. According to the technical scheme, the pressure in the balloon and the impedance outside the balloon are detected at the same time and compared with the set value and the set change range, accurate and automatic judgment of attachment of the ultrasonic ablation balloon and the blood vessel wall is achieved, it is ensured that ablation work is started after the ultrasonic ablation balloon is well attached to the wall, and the operation efficiency is improved. And the ultrasonic transmission efficiency and the ablation operation effect are greatly
