DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a surgical cosmetic apparatus for removing a variety of benign skin growths, especially on facial skin, eradicating underarm odor and unwanted hair once for all, recovering kinds of scars as well as making ear holes for earring by use of UHF electric current of about 50 MHz without any side effect on the human body, and pertains to the field of skin-beauty surgery.
BACKGROUND OF THE INVENTION
Conventional skin-beauty technique comprises such cosmetic treatments as cryotherapy, laser, erosion with Chinese traditional and modern medicines, skin polishing and the use of high frequency electric blade (mainly for surgical incision and stopping bleeding in operation). But there are following drawbacks in the use of the above-mentioned treatments: (1) contamination of the surgical wound surface, unsatisfactory evaporation of the inflicted tissues, and stickiness of the inflicted tissues; (2) the size and depth of the surgical treatment area being difficult to control, scars remaining after operation, relapse rate being high and the skin surface after treatment being rough. Several ultra-high-frequency cosmetic apparatuses have been proposed to overcome the above-mentioned drawbacks. A particular structure of this kind of cosmetic apparatus is disclosed in Chinese patent application No. 91104006 entitled "ultra-high-frequency cosmetic apparatus". However, it has the disadvantages of employing the commercially available "five sense organs treatment device" as the ultra-high-frequency signal source, which fails to provide, the required precision of the parameters of frequencies, stability indices, and safeguard when the naked metallic electrodes are directly applied on the human body.
It is therefore an object of the present invention to provide an improvement of the above-mentioned cosmetic apparatus, in which the ultra-high-frequency signal source outputs stable ultra-high-frequency signals with high precision parameters that enables the safe application of the naked metallic electrodes directly on human body.
SUMMARY OF THE INVENTION
The present invention provides an ultra-high-frequency cosmetic apparatus comprising an ultra-high-frequency signal source, output electrodes and a variety of surgical treatment appliances in the forms of needle and blade, characterized in that the ultra-high-frequency signal source is constituted by the following circuits: a tunable oscillating circuit for generating ultra-high-frequency oscillating signals; a power amplifying circuit connecting with an output intensity adjustment and display circuit, the input of the power amplifying circuit being connected to the output of the tunable oscillating circuit, a current and frequency stabilizing circuit having its input connected to the output of the power amplifying circuit and its output connected to the tunable oscillating circuit, a coupling isolating circuit having its input connected to the output of the power amplifying circuit and its output connected to the output electrodes and the variety of surgical treatment appliances; and a power supply circuit for providing electrical power to the circuits, the circuit connecting with a voltage adjustment and display circuit.
Preferably, the output signal of the apparatus has a frequency of 40-58 MHz and an intensity of 0-180 mA.
Preferably, the output signal of said ultra-high-frequency cosmetic apparatus has a frequency of 50 MHz.
Preferably, the ultra-high-frequency oscillating circuit uses FU-7 electronic tubes and an LC self-excited oscillating circuit.
Preferably, the power amplifying circuit employs a push-pull power amplifying circuit consisting of a pair of FU-7 tubes.
Preferably, the coupling isolating circuit employs two capacitors having resistance to voltage of more than 1 KV as isolating elements.
Preferably, the ultra-high-frequency cosmetic apparatus is provided with an air cooler.
The present invention also provides an ultra-high-frequency signal source, output electrodes and a variety of surgical treatment
