Description

Focused ultrasound therapeutic device and therapeutic method using same Technical Field The present invention relates to a focused ultrasound therapy device capable of performing surface irradiation of a spiral path and a therapy method using the same, which generates power by separately providing a driving device and adopts a conveying structure that moves an ultrasound output device along the spiral path under physical action, thereby not only changing the focus of ultrasound to achieve surface irradiation, but also enabling a more efficient production process and a relatively reasonable unit price through simplification of the structure, while significantly reducing a failure rate, and enabling a wider range of a therapy site with the miniaturization of the device. Background Conventionally, an ultrasonic wave generating apparatus-related technique is known that utilizes focused ultrasonic waves (focused ultrasound) generated by focusing ultrasonic waves generated by an ultrasonic wave generating apparatus to achieve treatment for skin beauty and therapeutic purposes. In general, an ultrasonic wave generating apparatus is designed mainly by a handle, which may be a main body of the ultrasonic wave generating apparatus designed to be easily held when a user uses the ultrasonic wave generating device, and a cartridge (cartridge), which may be a component having built-in ultrasonic wave transducers for generating ultrasonic waves and components necessary for driving the ultrasonic wave transducers and coupled to the handle. With the progress of research and development for applying focused ultrasonic waves to the skin of a subject, an ultrasonic wave generating device comprising such a handle and a tube has been variously modified in structure, and a corresponding treatment method has been rapidly spread in the medical and cosmetic industries. That is, various techniques have been disclosed for realizing ultrasonic surface irradiation by a plurality of linear conveyors (not a linear conveyor of a simple single structure) with respect to conventional transducers. However, the above-described conventional technique requires two or more driving devices (e.g., motors, etc.), which results in a complicated structure and a problem of a large-sized device and a cost burden. In particular, the enlargement of the device has a limitation in that it can treat only a large area of the body such as the middle abdomen, but it is difficult to treat a relatively small area of the face, and the like, in terms of the skin area of the subject. Therefore, there is an increasing demand for a skin beauty/treatment apparatus based on focused ultrasound, in which a technique is applied in which surface irradiation is also achieved by a relatively simple structure, an efficient production process and a reasonable production unit price can be expected, and a wide expansion can be achieved for a treatment target portion by miniaturization of the apparatus achieved by the simplification of the structure.
