Description

High Intensity Focused Ultrasonic Device with a Rotatable Transducer Module The present invention relates to a skincare device using ultrasound, and more specifically, to a High Intensity Focused Ultrasonic (HIFU) device used for skin beauty and treatment purposes. High-intensity focused ultrasound (HIFU) devices are used to necrotize or remove tumor tissue by focusing high-intensity ultrasound (focusing intensity of 1000 W/cm² or higher) onto a single focal point and applying direct heat to the human body. They are primarily used to treat cancers such as liver cancer, uterine cancer, and breast cancer. Due to the perception that treatment methods using HIFU are non-invasive, safer, and offer faster patient recovery compared to surgical procedures, the demand for such treatments is on the rise. While ultrasound is harmless when passing through human tissue, high-intensity ultrasound that forms a focus generates enough energy to cause necrosis regardless of the type of tissue. For HIFU devices, it is important to focus high-intensity energy onto a target focal point in the body through the linear/rotational movement of an ultrasonic transducer that converts electrical energy into mechanical energy within the ultrasonic frequency range; therefore, precise control of the transducer's movement is essential. Such HIFU devices are applied in various ways, and are used not only for the treatment of tumor tissue but also for cosmetic purposes such as wrinkle reduction and obesity treatment. By focusing ultrasound waves to damage tissue with high heat, they are effective in reducing wrinkles through the regeneration of collagen or the contraction of fascia. In order for a user to directly use a HIFU device at home on various curved body parts such as the face and jaw, it is required that the transducer be able to rotate at various angles.
