In the prior art, the spherical surface focusing transducer is the high-intensity focusing ultrasonic transducer of using always, also is one of several kinds of best ultrasonic transducer structures of focusing efficiency.Below be example just with the spherical surface focusing transducer, specify the workflow of the ultrasonic fat reducing treatment head of this utility model.
Step S1: obtain the treatment situation of treating area for treatment;
Before carrying out ultrasonic fat reducing treatment, ultrasonic fat reducing treatment head at first will obtain the treatment situation of treating area for treatment, to confirm size, position and the shape of needed focal spot according to the treatment situation.The treatment situation of being obtained comprises the fat deposit thickness of treating the area for treatment place and treats that area for treatment is positioned at the depth of fat deposit; Particularly, ultrasonic fat reducing treatment head obtains the fat deposit thickness of treating the area for treatment place and can realize through following steps: to treating that area for treatment launches a ultrasound wave burst pulse; Obtain the interval between second ultrasonic echo that the interface layer of first ultrasonic echo and fat and muscle of the interface layer reflection of coupling liquid and epidermis reflects; Interval multiply by behind the bulk sound velocity of fatty tissue divided by 2, obtain treating the fat deposit thickness of area for treatment.But realize that obtaining the fat deposit thickness of treating the area for treatment place is not limited to said method; Can also pass through skinfold kind of calliper, CT (computed tomography; The electronic computer x-ray tomography)/modes such as MRI (Magnetic Resonance Imaging, nuclear magnetic resonance) radiographic measurement realize;
Step S2: size, position and the shape of confirming the focal spot of needed ultrasonic transducer according to the treatment situation of treating area for treatment;
Ultrasonic fat reducing treatment head is after obtaining treating the fat deposit thickness at area for treatment place and treating that area for treatment is positioned at the depth of fat deposit; Just can confirm to treat size and the shape that focus is positioned at the subcutaneous degree of depth, focal spot, and select suitable-6 dB to focus on the axial length and the lateral length of focal spot.Illustrate: conclude a contract or treaty 20 millimeters fat deposit thickness for giving; Hope restriction spherical surface focusing transducer focusing acoustic field-6dB focal spot along the major diameter of acoustic axis direction less than 20 millimeters and suitably leave far and near safe distance (for example-the 6dB major diameter is 10 millimeters, the ultrasonic transducer focus is positioned at the fat deposit centre position).Be positioned at the shallow table of fat deposit in fat deposit focal position thin or the single ultrasonic irradiation or during near muscle and connective tissue interface, can adopt little focal spot, to guarantee to treat safety.When focal position thicker at fat deposit and the single ultrasonic irradiation is positioned at fat deposit intermediate depth position, can adopt big focal spot, treat fast under the prerequisite that guarantees focus far field and near field safety, to realize the big volume of single;
Step S3: the parameters of adjustment ultrasonic transducer, with size, position and the shape that obtains determined focal spot.
Particularly; Ultrasonic fat reducing treatment head can be through changing ultrasonic transducer and skin distance, change the ultrasonic transducer focal length, the focusing that changes ultrasonic transducer converges the angle, changes the ultrasonic transducer type of focusing, changes the methods such as frequency that ultrasonic transducer is launched sound wave, changes size, the shape of subcutaneous focal depth of ultrasonic transducer and/or focal spot region.
The implementation procedure of respectively programme of work of head is treated in the above-mentioned ultrasonic fat reducing of mentioning below describes:
(1) focal length, aperture and operation wavelength the size and the shape of a ultrasonic fat reducing treatment adjustment ultrasonic transducer to obtain determined focal spot
Scheme one: converge size and the focusing gain that the angle changes the focal spot of ultrasonic transducer through the focusing that changes ultrasonic transducer.
To converge the angle relevant with it for the size of spherical surface focusing transducer focal spot, the spherical surface focusing transducer to converge the angle big more, energy focusing is concentrated more, focal spot is then more little, focusing gain is big more, is fit to the meticulous treatment of single irradiation small size; Otherwise, the spherical surface focusing transducer to converge the angle more little, then energy focusing is overstepping the bounds of propriety looses, focal spot is big more, focusing gain is more little, is fit to the big volume of single irradiation and treats fast.Therefore, can focus on the size and the focusing gain of focal spot to realize control through the angle of converging of control spherical surface focusing transducer.
Can control through the effective emission area that changes the spherical surface focusing transducer and converge the angle.Because; The effective emission area that changes the spherical surface focusing transducer can change the equivalent transmitting aperture of spherical surface focusing transducer, thereby is equal to the ratio that changes focal length and aperture, and for the spherical surface focusing transducer; The ratio of focal length and aperture half value (ultrasonic transducer radius) is the sine function that partly converges the angle; Therefore, change the equivalent transmitting aperture of spherical surface focusing transducer, can carry out trickle adjustment converging the angle.
Scheme two: the focal length through changing ultrasonic transducer and the size and the focusing gain of the focal spot of aperture change ultrasonic transducer.
The fixing focal length of ultrasonic transducer, the aperture of adjustment ultrasonic transducer; Or the focal length of change ultrasonic transducer, the fixedly aperture of ultrasonic transducer; Or focal length and the aperture of adjusting ultrasonic transducer simultaneously obtain different focal length and aperture ratio, changes the size and the focusing gain of focal spot.
The approach that changes the aperture of ultrasonic transducer can comprise multi-electrode branch annular region excitation ultrasound transducer piezoelectric; Adopt sound-absorbing material to stop ultrasonic transducer part area; Or adopt many ultrasonic transducers structure to change effective transmitting aperture, and other similar schemes through the wherein some ultrasonic transducers of switch.
Scheme three:, change the size and the focusing gain of focal spot region through changing the operating frequency of ultrasonic transducer.
Specific embodiments: for the spherical surface focusing transducer, the ratio in the axial dimension of focal spot and its operation wavelength (being the corresponding wavelength of operating frequency) and its focal length and aperture square relevant, the lateral dimension of focal spot is relevant with the ratio in its operation wavelength and focal length and aperture.The ratio in wavelength or focal length and aperture is big more, and the axial dimension of spherical surface focusing transducer and lateral dimension are just big more.Therefore, can pass through to change size and the shape of the operating frequency of spherical surface focusing transducer with the control focal spot.
The operating frequency that changes ultrasonic transducer can cooperate suitable power amplifier to realize to the impedance matching of ultrasonic transducer by drive circuit.For the ultrasonic transducer under the broadband work pattern, can select the suitable high frequency or the size and the focusing gain of low frequencies signal change focal spot region in real time to fat deposit thickness.
The axial dimension of focal spot and the adjustment of lateral dimension can also be through changing ultrasonic transducer the type of focusing (sphere self-focusing, cylinder self-focusing, axially bend and stretch focusing, transverse compression or stretch focus on) realize.
Further, can also adopt the mode of sound lens focusing, effective area for treatment that manufacturing needs; For example, in order to enlarge the focal spot overlay area of single therapy, adopt the cylinder acoustic lens to cooperate the rectangle plane potsherd to make planar focal zone and can remedy the too small limitation of sphere self-focusing focus; Perhaps adopt multifocal acoustic lens to realize that single emission obtains a plurality of focuses simultaneously.Again for example, change the lens of different curvature radius, under the situation that does not change the ultrasonic transducer piezoelectric element, change to focus on and converge the angle, obtain different focus characteristics.
(2) distance of ultrasonic fat reducing treatment head through changing ultrasonic transducer focal length, ultrasonic transducer and skin is to obtain the position of determined focal spot
The treatment target site of treating area for treatment often is meant the focal position and the focal spot region thereof of ultrasonic transducer.The focal length of ultrasonic transducer is meant that the ultrasonic transducer piezoelectric material surface focuses on the distance of focus to ultrasonic transducer; In the ultrasonic fat reducing treatment of typical subcutaneous layer of fat, the distance of ultrasonic transducer surface distance skin is positioned at the focal length that subcutaneous degree of depth sum equals ultrasonic transducer with the ultrasonic transducer focus.
After definite focal spot is positioned at subcutaneous position, can change the degree of depth of treatment target site in fat deposit apart from the distance of epidermis or the mode that changes the focal length of ultrasonic transducer through the adjustment ultrasonic transducer.
Scheme one: change the degree of depth of treatment target site in fat deposit through the distance that changes transducer and skin
Specific embodiments one: can adopt suitable elastic materials to make ultrasonic transducer front end coupling liquid capsule, this coupling liquid capsule and ultrasonic transducer coupling liquid road and liquid storage container UNICOM.The seal that keeps ultrasonic transducer water circuit system (coupling liquid capsule, liquid road, liquid storage container); Utilize hydraulic principle; Adopt suitable hydraulic driving mode (for example method such as charge pump, similar needle cylinder injection suction) in liquid storage container, to get into ultrasonic transducer front end coupling liquid capsule, through increasing the purpose that the liquid capsule volume reaches increases the degree of depth of treatment target site in fat deposit to liquid road output liquid; Otherwise, can reduce the liquid capsule volume through the coupling liquid in the aspirated liquid capsule, reduce to treat the degree of depth of target site in fat deposit.Since the surface tension of liquid each to evenly, it is smooth and smooth that the elastica material can keep in suitable elastic range, is convenient to through ultrasonic energy.
The structure of ultrasonic transducer front end coupling liquid capsule can be isotropic elastic construction (the for example mode of balloon harmomegathus); Or the elastic construction (for example liquid capsule side adopts rigid material to limit its harmomegathus) that has bounds to limit; Or have bounds restriction liquid capsule side to add mechanically-propelled liquid capsule front end face (for example telescope focusing mode), or adopt movable hard supporting construction (for example umbrella opening-closing structure).Owing to the seal of liquid-way system, the change of distance can pass through to measure the variation reckoning of liquid capacity in the liquid storage container, and information feedback should distance to hydraulic pressure driving maintenance or adjustment in view of the above.Adopt the Electromechanical Control method can accurately control the change of liquid capsule volume, and be adapted at adjustment in real time in the therapeutic process.The increase and decrease of liquid CF body also is convenient to dispel the heat to the ultrasonic transducer piezoelectric.
Specific embodiments two: adopt mechanical system; For example manually or motor drive mechanism push-and-pull ultrasonic transducer piezoelectric and encapsulation base station thereof up and down; Adjustment ultrasonic transducer piezoelectric is adjusted distance in the degree of depth of Level Change treatment target site in fat deposit of treatment head inside in the also suitable treatment of this scheme in real time.
Specific embodiments three: unite and adopt above-mentioned two kinds of specific embodiments adjustment distance.
Specific embodiments four: adopt solid-state the material of leading of differing heights, for example the acoustic impedance characteristic as couplant, also can change the distance of ultrasonic transducer surface to skin surface near the hydrogel of tissue.
Scheme two: change the degree of depth of treatment target site in fat deposit through changing the ultrasonic transducer focal length.
Specific embodiments one: the sphere curvature radius that changes the ultrasonic transducer piezoelectric is the way that the most directly changes the ultrasonic transducer focal length.Based on the thinking that changes sphere curvature radius, can also adopt the ultrasonic transducer structure of split-type, the folding angle through a plurality of limbs changes focal length; Or adopt ring-type phased ultrasound transducer method to change focal length; Or adopt the odd-shaped method of other similar focusing surfaces to change focal length.
Above-mentioned ultrasonic fat reducing treatment head obtains the treatment situation of treating area for treatment earlier; The process of the parameter of the preferred ultrasonic transducer in back can the order intersection be carried out in ultrasonic fat reducing therapeutic process; Or measure earlier before the treatment and the labelling fat thickness with the variation of position, in treatment subsequently according to the parameter of the preferred ultrasonic transducer of thickness information.
More than the scheme of size, position and shape of ultrasonic fat reducing treatment head adjustment focal spot do not limit to and be used for the spherical surface focusing transducer, can also be applicable to that the self-focusing of broad sense sphere, broad sense cylindrical focusing, multi-clove type focus on, the plane piezoelectric patches cooperates acoustic lens list focus or structures such as multiple-point focusing, polycyclic focus on, phased array list focus or multiple-point focusing.
Except that the static therapeutic scheme of above-mentioned ultrasonic fat reducing treatment head; The ultrasonic fat reducing treatment head of this utility model embodiment can also dynamically be treated; Such as moving ultrasonic transducer continuous sweep area for treatment through machinery; Ultrasonic transducer is continuously with specific pulse recurrence frequency emitted energy, so that promptly change focal spot position, focal spot size more flexibly simultaneously.This scheme possibly cause some kinds of tissue effects; Because the bubble cloud effect that is produced between the closely adjacent emission focus; A focal position can be by the remaining bubble cloud of emission last time on the next-door neighbour; Excite the acoustic cavitation of current location with lower ultrasonic energy, or produce because the enhanced heat effect of organizing that acoustic cavitation causes, or have concurrently to produce simultaneously and organize heat effect and non-thermomechanical effect.Be equipped with suitable real-time monitoring means, next-door neighbour's continuous emitting treatment pattern can utilize energy still less to keep the sound cavitation effect in the whole therapeutic process, accelerates treatment speed, shortens treatment time.Reach volume therapeutic effect more uniformly.
Concrete implementation can be made the relative slide displacement between patient skin and the treatment head for utilizing the mechanical displacement control system, guarantees that the movement locus (focus motion track) of treatment head covers whole area for treatment.Simultaneously, the ultrasonic transducer in the treatment head adopts preferred acoustic emission parameter (ultrasonic frequency, pulse amplitude, pulse width and pulse recurrence frequency) emission ultrasound wave to treat according to a treatment translational speed and direction.Use ultrasound wave or infrared ray sensor that the acoustic cavitation in the therapeutic process and subcutaneous tissue temperature or real-time ultrasonic image are fed back and monitor in real time, adjust the parameter of acoustic emission next time according to monitoring result.Next treatment position can suitably be adjusted spacing distance (accelerating or the treatment translational speed that slows down) according to cavitation intensity, scope or the variations in temperature size of a last treatment position, improves the effectively assurance of treatment.Other implementations can move or the machinery of swing (modes such as micromotor transmission, hydraulic pressure, pneumatic, spring) realizes treating the compound motion of head and ultrasonic transducer at a treatment built-in control ultrasonic transducer among a small circle, or adopt the phased array mode to replace the built-in travel mechanism of ultrasonic transducer realization focus electronic deflection; Its purpose is to realize focus move mode flexibly.The scheme of adjustment focus shift speed and preferred emission parameter can be optimized the treatment pattern in moving continuously, and comprehensively selecting for use with mechanical effect or heat effect is that master or combined effect carry out the treatment of fat destruction.
The above is the preferred implementation of this utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the said principle of this utility model, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of this utility model.
