Ultrasonic intravascular stent device

An ultrasonic intravascular stent device, comprising a stent, wherein a micro ultrasonic vibration module is mounted on the stent;

• the micro ultrasonic vibration module comprises a housing and a housing cover assembled to each other, wherein an accommodating cavity is defined between an enclosure formed by the housing and the housing cover;
• the micro ultrasonic vibration module also comprises an ultrasonic vibration assembly and a driving control assembly, both disposed in the accommodating cavity;
• the ultrasonic vibration assembly comprises a slidable block, resilient tabs disposed at two ends of the slidable block respectively, and at least one driving coil;
• at least one permanent magnet block is provided on the slidable block;
• the resilient tabs provides buffering and bouncing functions against the slidable block as the slidable block slides;
• said at least one driving coil cooperates with said at least one permanent magnet block to generate a magnetic driving effect;
• the driving control assembly comprises a circuit board on which a wireless communication module is disposed, and a battery and a wireless charging coil which are electrically connected to the circuit board;
• said at least one driving coil is electrically connected to the circuit board to drive the ultrasonic vibration assembly to work.
