The present invention relates to an obesity treatment apparatus using ultrasonic waves, and more particularly, to a three-axis control head of a non-invasive subcutaneous fat reduction apparatus using high intensity focused ultrasound (HIFU).

Recently, as the diet became westernized, obesity rapidly increased and became the biggest cause of harming national health and beauty, and various diet programs and ultrasonic obesity treatment devices have been developed and widely used to treat them.

High Intensity Focused Ultrasound (HIFU) obesity treatment technology was originally used for non-invasive chemotherapy to destroy cancer cells by selectively coagulating internal organ tumors at high temperature. The company first developed a device called Liposonix with HIFU. The process of fat destruction using high intensity focused ultrasound (HIFU) is that when the integrated ultrasound is focused at a certain point of fat cells, the temperature of the tissue rises instantaneously from 65 ° C. to 100 ° C., thereby causing the tissue to be destroyed. HIFU equipment, unlike other dermatological instruments such as laser and RF radiofrequency equipment, concentrates HIFU energy in non-invasive selected areas without causing any damage to the surface of the skin to induce fat coagulation necrosis. do. These necrotic fat cells are naturally removed by our body's damage repair mechanism.
