The specific embodiment
The present invention relates to use the contact skin cooling to carry out equipment and the method that physical shapes is repaired under the non-intrusion type ultrasonic guidance.With reference to description and accompanying drawing, carry out principle and the operation that physical shapes is repaired under the non-intrusion type ultrasonic guidance with understanding use skin cooling according to the present invention better.
Referring now to accompanying drawing, Fig. 1 shows the perspective view of physical shapes prosthetic appliance under the ultrasonic guidance according to the preferred embodiment of the invention.Treatment applicator 10 is connected to control unit 12 via connection cord 14.Ultrasonic transmitter 16 (for example, piezoelectric element) is positioned at the end of treatment applicator 10.Control unit 12 can be used to scan the output frequency of the ultrasonic transmitter 16 on the scheduled frequency range.
In the preferred embodiment of the present invention, resonant transducer 18 (for example, using ultra sonic imaging or impedance-measurement techniques) is connected to control unit 12, and is used to regulate the output frequency and the power of ultrasonic transmitter 16.Carry out scan period at the output frequency by 12 pairs of ultrasonic transmitters 16 of control unit, resonant transducer 18 is determined resonant frequency.Control unit 12 uses the operating frequency of resonant frequency as ultrasonic transmitter 16, thereby uses minimum power and the optimization treatment.Perhaps, control unit 12 also can be in the limited range that with the resonant frequency is the center output frequency of continuous sweep ultrasonic transmitter 16.In other preferred embodiment, resonant transducer 18 is positioned at the head (not shown) that is independent of treatment applicator 10.
In the preferred embodiment of the present invention, control unit 12 configuration makes treatment applicator 10 (for example, 20-500kHz) go up and discharge ultrasound emission at wide frequency ranges.In a preferred embodiment, adopt the operating frequency range of the ultrasound emission of 25-60kHz.Control unit 12 starts and controls single piezoelectric element (being ultrasonic transmitter 16) so that ultrasound emission to be provided.
In resonance frequency mode, fixed-frequency is in predetermined resonant frequency, and it depends on volume, density and the degree of depth of the fatty tissue of being treated, so that produce effective cavitation bubble.For optimization treatment effectiveness, must determine the resonant frequency relevant with fatty tissue, it does not cause the effect to surrounding tissue.
In continuous wave mode, ultrasound emission is applied to area for treatment continuously.Owing in treatment applicator 10, have cooling body (below with more detailed description), therefore can carry out the single course of treatment.In burst-cycle mode, control unit 12 is with the operation of ON/OFF dutycycle, so that various treatment pulses to be provided, so that create more substantial microvesicle.And because local pressure gradient, this burst mode operation can be created shock wave, has strengthened the effectiveness of treatment.
The resonance absorbing of ultrasound emission depends on cavitation size, tissue density and the tissue depth of the tissue of being treated.Manually or automatically determine resonant frequency by control unit 12 uses from the data signal of the resonant transducer 18 in the treatment applicator 10.The microvesicle that produces in fatty tissue owing to be exposed to ultrasound emission is because the pressure variation of (because skin surface micro-injection and heating effect down do not produce undesirable heat effect at skin contact surface) and dissolved fat tissue when expanding and collapsing.
In a preferred embodiment of the invention, the coolant that circulates in the circuit 20 in cooling is used for being dissipated in via thermoelectric (al) cooler 22 heat that is produced by ultrasonic transmitter 16 under the contact skin refrigerating mode.Thermoelectric (al) cooler 22 is connected to treatment applicator 10 via cooling circuit 20, provides cooling with the circular chamber to ultrasonic transmitter 16 all the time.When equipment operates in disresonance frequence and/or during with continuous wave mode, this cooling is particularly important.
In other preferred embodiment, electric stimulation electrode 24 is installed on the treatment applicator 10, is used to provide enhanced treatment ability.Electric stimulation electrode 24 applies low frequency, and (for example, 5-500Hz) electric current so that stimulate and shrinkage tissue, thereby strengthens cavitation effect to intermediate frequency.Electric stimulation electrode 24 can also be configured to provide electric current with RF frequency range (for example, 1 to 10MHz) in the electric insulation probe.During operation, antielectrode 26 is provided with patient's body and contacts to form complete circuit.
Fig. 2 A shows the partial cut figure of the treatment applicator of equipment according to the preferred embodiment of the invention.In a preferred embodiment, treatment applicator 10 is configured to provide topical therapeutic.Treatment applicator 10 is shown the latter half of removing shell 28 in Fig. 2 A, to appear the internal part for the treatment of applicator 10.
Via cooling circuit 20, thermoelectric (al) cooler 22 can be at the temperature required cooling of regulating via circulating that sheath 30 provides to ultrasonic transmitter 16.Circulating sheath 30 is preferably made by aluminum or another light Heat Conduction Material.By cooling circuit 20 flowing coolant, flow through the cooling duct 32 in the ultrasonic transmitter 16.It is necessary that piezoelectric element in the ultrasonic transmitter 16 is cooled off, so that prevent superheated (operating in disresonance frequence and/or continuous wave mode simultaneously), providing comfort level, and allow continued operation during treating to the patient, and can be owing to " cooling " stage is interrupted.During frequency scanning, piezoelectric element produces quite a large amount of heats.
Fig. 2 B shows the end-view of the skin contact surface of the treatment applicator of Fig. 2 A according to the preferred embodiment of the invention.Resonant transducer 18 and electric stimulation electrode 24 are shown the shell 28 outside the zone that is arranged in ultrasonic transmitter 16.
Though the embodiment with reference to limited quantity has described the present invention, should be realized, can make many changes, modification and other application to the present invention.
