In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

First, before looking specifically at the high-intensity focused ultrasound generating device having a treatment site slip prevention function according to the present invention, a brief description will be made of the features of the ultrasound procedure that can be used in the medical or cosmetic fields.

First, ultrasonic waves have transmission and reflection properties. According to this property, the ultrasound irradiated to a specific part of the human body is used as a means of visualizing the time and intensity reflected while passing through the corresponding organ to obtain the cross-sectional image.

Second, the ultrasonic wave has a mechanical function of exerting an ultrasonic vibration on a surgical knife and the like, thereby exerting an effect such as cutting.

Third, the sound pressure of the ultrasonic wave generates fine bubbles in the fluid as it passes through the fluid. In this case, the generated bubbles are implemented in the form of shockwaves having a high pressure as they expand and rupture. This action involves a strong shear force.

Fourth, ultrasonic waves are converted into thermal energy while being absorbed by the tissue. Ultrasound with sufficient energy can cause a sharp rise in temperature in the tissue, which is called the thermal effect of ultrasound.

The high intensity focused ultrasound generation device in the present invention corresponds to a medical device using the thermal effect of such an ultrasound. Among them, high intensity focused ultrasound is a form in which an ultrasonic wave generated by an ultrasonic transducer is focused at a constant focusing point (ie, focus) to enhance intensity. The high-intensity focused ultrasound irradiated into the tissue treats various cancers by the thermal method using the thermal effect generated at the focus, and does not leave a wound or side effects on the human body. In particular, there is an advantage that does not involve pain.

In addition, high-intensity focused ultrasound is a technique that is recently attracting attention as it specializes in dermatology, especially skin wrinkle improvement, among medical procedures. Ultrasonic energy having a relatively low intensity can be formed at a fine junction to exert an effect of improving skin wrinkles.

The skin structure of the human body consists of the epidermis, the dermis, the subcutaneous fat, the muscle layer, and the skeleton in order from the outside. Among these, most of the constituents of the dermis are collagen. This ingredient is responsible for maintaining skin elasticity.
