Patent of the present invention adopts array micropin mode as radio-frequency electrode, drive rod is driven by the magnetic drive pump in micropin emitter, drive rod is travelled forward, and the base plate promoted in treatment syringe needle moves forward, micropin is squeezed into skin corium or fat deposit instantaneously, as subcutaneous 2mm, then launch radio frequency, carry out radio-frequency (RF) therapy; After having treated, reset electric magnet makes magnetic drive pump reset, and drives drive rod mobile playback backward, and drive rod acts on the distress resolves on base plate, and under the effect of recoil of spring power, base plate and micropin reset backward.
The present invention gos deep into subcutaneous transmitting radio frequency, ensure that the action effect of target tissue, simultaneously; present invention improves the unfavorable factor of skin for radio frequency electromagnetic non-selectivity; adopt dot matrix micropin mode, invade skin corium and launch radio frequency, good protection has been carried out to epidermis.The present invention can be widely used in skin or beauty therapeutic, and concrete has: wrinkle, cutis laxa, cicatrix, cicatrix, hyperhidrosis; Effect target tissue can be skin corium, and also can be subcutaneous layer of fat, also can be sweat gland tissue.
Because skin histology is soft tissue, be needled in process and have difficulties, smooth compressing skin histology is needed in therapeutic process, by instantaneously launch thrust subcutaneous, micropin translational speed need avoid enough soon because of skin histology be soft tissue cause penetrate obstacle, meanwhile, speed is faster, and the pain in therapeutic process is lower.Therefore, the translational speed of micropin needs to reach 100mm/s, even 1000mm/s.
Treatment syringe needle is installed by removably, can pull down and carry out disinfection, so that patient's secondary uses, and having certain access times, is consumptive material.
The output frequency of described main frame (1) interior radio-frequency power supply is 0.3MHz-100MHz, this radio-frequency power supply for export continuously or pulse exports or continuously and pulse jointly export three kinds of modes.The therapeutic modality of radio frequency has two kinds, and the first is pulse mode treatment, and the second is continuation mode treatment.And the time of therapeutic modality generally needs 1-10s continuously, with crossing the object slow heating of skin histology being realized to treatment, the temperature of target region can control usually at 40-50 DEG C, can have good curative effect, does not damage surrounding tissue again.Pulse mode is completed treatment in 0.1-0.5s generally, because treatment time is short, the tolerable temperature of skin can be higher, and temperature 60-70 DEG C of usual target region has the newborn and consolidated fibers of good stimulation collagen and organize curative effect, if more than 75 DEG C, can there is necrosis in area for treatment skin histology.The treatment time of two kinds of therapeutic modalities there are differences, and target tissue region temperature exists significant difference simultaneously.
Radio-frequency (RF) therapy can be divided into one pole handle and bipolar handle.Bipolar handle forms current loop at therapeutic target tissue regions, and over the course for the treatment of, somagenic need pastes negative plate to form current loop to one pole handle in addition.
In bipolar treatment handle, the one pole bipolar arrangement mode of micropin has multiple, total positive number of poles and negative pole quantity basically identical, even to ensure each electrode place Energy distribution.Electric current forms loop between a positive electrode and a negative electrode, if having two positive poles, a negative pole, then the energy that negative pole carries is the twice of positive pole, and micropin specification is consistent simultaneously, then energy density on cathode is significantly 2 times of positive pole, can cause overmedication.
The present invention also has automatic impedance matching function: the electromagnetic wave that main frame exports is through the anelectrode of cable transmission to radio-frequency treatment head, loop is formed through negative electrode, system detection of skin impedance at short notice, correspondence calculates power demand density, again exports power demand density.Adopt impedance match technique, guarantee different people, different parts all can receive the output dose of setting.Control inerface arranges warning temperature to treatment temperature simultaneously, and as pulse mode exports, arranging therapeutic dose is 0.1J, and arranging treatment warning temperature is 75 DEG C, if when therapeutic dose just exports 0.05J, treatment temperature just gets to 75 DEG C, then equipment stops launching radio-frequency (RF) energy.
Temperature sensor is equipped with a micropin (73) wherein, for carrying out Temperature Feedback, to guarantee the safety of skin histology in therapeutic process.If when temperature sensor feedback monitor temperature exceedes the warning temperature of setting, carry out mandatory stopping radio-frequency energy transmission.Different according to radio-frequency (RF) therapy mode, the controlling alarm temperature difference to some extent of default, in continuous mode, setting alarm temperature controls as 45-50 DEG C, and concrete may be 50 DEG C; In pulse mode, setting warning temperature controls as 70-75 DEG C, and concrete may be 75 DEG C.
Micropin main material is medical stainless steel, except that root micropin being provided with temperature sensor, the ground of all the other micropins (73) is coated with containing golden deielectric-coating, good like this control metal heated after impedance change, be beneficial to the stable output of setting dosage, the temperature-coefficient of electrical resistance of gold is only 56% of stainless temperature-coefficient of electrical resistance.
