Leakage-preventing coupling structure of transducer array of high-intensity focused ultrasound generator, and transducer array

A leakage-preventing coupling structure of a transducer array of a high-intensity focused ultrasound generator high-intensity, comprising:

• an ultrasonic radiation frame having a plurality of coupling holes formed therein;
• a plurality of transducer holders respectively inserted into the plurality of coupling holes and detachably coupled to the ultrasonic radiation frame;
• and
• a plurality of transducers respectively mounted in an open front surface of at least a part of the plurality of transducer holders,
• wherein the transducer holder comprises:
• a head portion mounted on the ultrasonic radiation frame and having a seating groove in which the transducer is insertedly seated, formed therein;
• and
• a body portion extending from the head portion backward and coupled to the coupling holes using a fastening member from a rear of the ultrasonic radiation frame while passing through the coupling holes,
• the body portion of the transducer holder comprising a shaft portion extending from the head portion backward and being pressed into the coupling holes, and a screw portion extending from the shaft portion backward and coupled to the fastening member in the rear of the ultrasonic radiation frame after passing through the coupling holes, and
• the transducer holder further comprises a second sealing member, the second sealing member comprising an O-ring inserted outside the shaft portion, and an O-ring pressing member inserted outside the shaft portion from a rear of the O-ring and allowing the O-ring to be in close contact with the rear surface of the ultrasonic radiation.
