The specific embodiment
With reference to accompanying drawing and the embodiment of the detailed presentations method that will clearly understand advantage of the present invention and characteristic and realize these hereinafter.But the present invention is not limited to the embodiment of following discloses, and is presented as with mutually different various forms.The embodiment that here describes only is used to guarantee that disclosure of the present invention is complete, helps the those of ordinary skill of the affiliated technical field of the present invention to understand scope of the present invention fully.And, in the process that the present invention will be described, obscure principle of the present invention if be judged as relevant known technology etc., will omit its detailed description.
At first, before high-intensity focusing ultrasonic wave generator of the present invention is described, learn about earlier the characteristic that the ultrasound wave that can be applied to medical field or beauty treatment fields is performed a surgical operation simply.
The first, ultrasound wave has and penetrates and reflectivity properties.Therefore the ultrasound wave of irradiation uses time and the intensity that reflects when penetrating human organ of opposing to carry out the visualization processing, obtains the instrument of cross-sectional image.
The second, ultrasound wave has and applies the mechanics effect of the ultrasonic vibration of be used to perform a surgical operation (particularly cutting) to performing a surgical operation with cutter etc.
When three, hyperacoustic acoustic pressure is through fluid, make the fine foam of the inner generation of fluid, at this moment, the foam that is produced is presented as the shock wave (shockwave) of high pressure form along with expanding and breaking.It is accompanied by stronger shearing force (shearing force).
Four, ultrasound wave is passed in the tissue and is converted into heat energy by tissue absorption.Ultrasound wave with enough energy can make in-house temperature sharply rise, and is called hyperacoustic thermal effect.
High-intensity focusing ultrasonic wave generator of the present invention is equivalent to utilize the medical apparatus and instruments of this hyperacoustic thermal effect.Wherein, high-intensity focusing ultrasonic wave (High Intensity Focused Ultrasound) is to make the ultrasound wave that results from the ultrasonic transducer focus on the focus point (being focus) of regulation, strengthens the form of intensity.Shine in-house high-intensity focusing ultrasonic wave and be utilized in the thermal effect that focus produces, treat various cancers with warm mode, can not stay any wound or side effect to human body this moment.Particularly, can carry out painless selective local cancer treatment.
And then this high-intensity focusing ultrasonic wave also distinguishingly is used to improve wrinkle of skin etc. in medical treatment is performed a surgical operation, and is kind of a technology of favoring recently.Particularly, form lower ultrasonic energy of intensity and fine focus point, confirmed the remarkable effect of improving wrinkle of skin.
The skin texture ecto-entad of human body is formed with the order of epidermal area, skin corium, subcutaneous layer of fat, Musclar layer, skeleton, and most of component of wherein forming skin corium is a kind of composition that is called collagen, and it has the function of the skin elasticity kept.
High-intensity focusing ultrasonic wave is not to epidermal area generation effect; And act on aponeurosis (Superficial Musculo-Aponeurotic System as the part of Musclar layer; SMAS) layer not only causes consolidation, can also heat be passed to the depths of skin corium.Finally make collagen regeneration, play and to remove wrinkle, can also improve the effect of skin elastic force.
Below, one by one preferred first, second, third, fourth embodiment of high-intensity focusing ultrasonic wave generator of the present invention is described with reference to accompanying drawing.
