2. A therapeutic ultrasound generation device comprising:
a cartridge housing unit;
an ultrasonic transducer unit positioned in the cartridge housing unit and disposed inclined with respect to a direction of a rotational central axis direction, thereby being configured to generate ultrasonic waves in an inclined direction;
an inclined block unit positioned in the cartridge housing unit, having an inclined surface on a lower surface thereof, and supporting an upper surface of the ultrasonic transducer unit, thereby positioning the ultrasonic transducer unit to be inclined with respect to the rotational central axis direction;
a rotating motor configured to rotate the inclined block unit; and
a torsion bar member which has a first end portion connected to the ultrasonic transducer unit and which has a second end portion connected to the cartridge housing unit,
wherein the torsion bar member comprises:
a first mounting unit mounted on the ultrasonic transducer unit;
a second mounting unit mounted on an inner surface of the cartridge housing unit; and
a torsion spring unit having opposite end portions thereof respectively connected to the first mounting unit and the second mounting unit, the torsion spring unit absorbing shock with torsional elasticity, and
wherein the torsion bar member is provided as a pair of torsion bar members positioned to be facing each other, and in the pair of torsion bar members, each torsion spring unit is formed with a shape and length to use torsional elasticity and absorb shock that is generated when the ultrasonic transducer unit is continuously inclined in all directions of 360 degrees.
