Description

[0001] MULTI-FUNCTIONAL HIGH INTENSITY FOCUSED ULTRASONIC CARTRIDGE AND HANDPIECE [0002]

The present invention relates to a cartridge and a handpiece that emit medical high intensity focused ultrasound (HIFU) capable of providing an additional function.

High Intensity Focused Ultrasound (HIFU) therapy was originally used for non-invasive chemotherapy to selectively destroy high-temperature coagulation of internal organs and to destroy cancer cells. It is being used more actively.

The principle of removal of adipose tissue using HIFU is that when the ultrasound is focused at a certain point on the adipose tissue, the tissue temperature instantly rises from 65 ° C to 100 ° C to destroy the tissue. Unlike other dermatological equipment, such as laser and RF high frequency equipment, HIFU equipment concentrates HIFU energy on non-invasively selected areas without causing any damage to the skin surface, leading to coagulation necrosis of adipose tissue. These necrotic adipocytes are naturally removed by our body's repair mechanism.

On the other hand, as a handpiece in the conventional HIFU equipment, reference can be made to the registered patent publication No. 10-1307551 (handpiece of the ultrasonic device). The handpiece 100 of the ultrasonic device is composed of a handpiece body 110 and a cartridge 120 which is attached to the handpiece body (see FIG. 1)

The handpiece 100 according to the conventional art operates the actuator 114 according to the control of the controller main body 110 to disperse the strong energy of the transducer 130 in a linear form and sequentially move while irradiating It is possible to maximize the lifting effect by injecting energy in the form of cotton, and additionally, effective treatment such as stain, pigmentation, acne, hyperhidrosis, and fever.

However, in the handpiece according to the related art, when the linear actuator 114 linearly moves, the slider 126 of the cartridge is transferred horizontally in the horizontal direction with reference to the drawing by the power transmitting magnet 123, (130) linearly moves.

In the structure provided with such an actuator, the size of the actuator is relatively large as compared with that of the cartridge, so that it must be configured separately from the cartridge.

On the other hand, the inside of the cartridge is filled with liquid such as distilled water, and the transducer is configured to move within the cartridge.

However, in order to allow the linear movement force of the actuator to be transmitted to the internal transducer while maintaining the seal of the cartridge in the structure of separately configuring the cartridge and the actuator, the complexity of the structure, the difficulty of design, Which is accompanied by an increase in cost.

Patent Registration No. 10-1307551

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cartridge in which an actuator can be installed inside a cartridge, without enlarging the size of the cartridge, thereby solving the problems associated with sealing the cartridge and simplifying the structure and weight of the handpiece.

Hereinafter, preferred embodiments of a multifunctional high-intensity focusing type ultrasonic emission cartridge and a handpiece according to the present invention will be described with reference to the accompanying drawings. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments of the invention only and is not intended to be limiting.

First, the configuration of a multi-function high-intensity focusing type ultrasonic handpiece according to the present invention will be described with reference to a block diagram of Fig. Referring to the drawings, a multifunctional high-intensity focusing type ultrasonic handpiece 200 according to the present invention has a structure in which a cartridge 201 and a handle 202 are coupled to each other. The cartridge 201 includes a HIFU output unit 210 and a driving unit 220 A high frequency stimulation unit 240 and a near infrared ray output unit 240. The handle 202 may include a power input unit 270, an oscillator 280, and an ultrasonic power source unit 290.

The handle 202 has an outer shape that the practitioner can grasp and can be connected to the controller body (not shown) with a cable-like wire. A control command for the power supply and the handpiece may be applied from the controller main body. And the supplied power is supplied to the cartridge 201. [ The handle 202 may have a built-in battery therein so that it can operate independently of the controller body.

The cartridge 201 is used in combination with the handle 202 and can receive power from the handle 202 to perform its function. The cartridge 201 outputs the energy of the HIFU to the subject's skin according to the operation of the operator or the controller body of the operation means (not shown) provided on the handle 202. [ At this time, the HIFU outputted from the transducer is dispersed in a line form and the transducer is horizontally moved by itself, so that the HIFU can be irradiated to the skin in the form of a plane. In this way, HIFU is irradiated in the form of cotton, thereby causing lifting, staining, pigmentation, acne, hyperhidrosis, and odor reduction in the skin of the recipient.

Cartridge 201 and handle 202 may each include electrical contacts 291 and 292 that may be connected to each other when coupled to each other.

The HIFU output section 210, the driving section 220, the high frequency magnetic pole section 240 and the near infrared ray output section 240 can be accommodated in the internal space of the cartridge 201. [

The HIFU output unit 210 operates by receiving the ultrasonic pulse power from the handle side through the first electrical contact 291 and is capable of outputting a high intensity focusing type ultrasound wave (HIFU) toward the skin of the patient.

The HIFU output unit 210 can move in an arbitrary direction within the internal space of the cartridge 201 according to the operation of the driving unit 220. [ In particular, the HIFU output unit 210 is configured to output a line-shaped HIFU to the skin of the client and the driver 220 can move the HIFU output unit 210 in a direction crossing the line shape. .

The driving unit 220 may include an ultrasonic motor 221, a stroke 222, and a moving mechanism 223 to move the HIFU output unit 210.

Basically, an ultrasonic motor (or a piezoelectric motor) includes two piezoelectric plates. When a pulse power of a frequency (30 to 60 KHz) corresponding to ultrasonic waves is applied to the piezoelectric plate, a torque is generated due to a twist phenomenon of the piezoelectric element. Ultrasonic motors are excellent in ultra high speed and precise position control ability to stop and stop accurate position within a short time. In addition, since the ultrasonic wave is used as a power source, it can be made lighter and smaller, so that it has no noise and almost no electromagnetic interference.

The ultrasonic motor 221 used in the handpiece 200 according to the present invention can have an encoder resolution of 24 bits (16 million pulses per rotation), thereby precisely positioning the transducer outputting the HIFU Can be controlled.

The stroke 222 is a member that rotates by the rotational force of the ultrasonic motor 221. The stroke 222 may be, for example, in the form of a rod, which may be threaded.

The moving mechanism 223 is a member configured to be movable along the stroke 222 when the stroke 222 rotates. The moving mechanism 223 may be provided with a thread corresponding to the thread of the stroke 222 so that the moving mechanism 223 moves in accordance with the movement of the thread due to the rotation of the stroke 222. [

The moving mechanism 223 may be provided with a HIFU output unit 210, in particular, a transducer for outputting a HIFU, and the irradiated position of the HIFU is moved by the movement of the moving mechanism 223.

At this time, since the ultrasonic motor 221 is small in size while providing sufficient torque to rotate the stroke 222, it is easy to be embedded in the cartridge 201. Therefore, only the electrical contact for receiving the ultrasonic power for driving the ultrasonic motor can be exposed externally from the cartridge 201, so that the waterproof structure of the cartridge can be simply completed. Referring to FIG. 1, an existing cartridge is required to have a large number of parts for disposing the actuator on the outside of the cartridge, i.e., the handle side, and for transmitting the driving force of the actuator to the moving mechanism inside the cartridge.

It will be apparent to those skilled in the art that the manner of moving the transducer by the threaded stroke 222 and the threaded movement mechanism 223 is only one example, and that other modes of motion can be used. For example, a method of driving the belt by the ultrasonic motor 221 and moving the transducer by the belt may be considered. Alternatively, a method of driving the friction wheel by the ultrasonic motor 221 and moving the transducer by the friction wheel may also be considered.

On the other hand, the handle 202 constituting the main contour of the handpiece 200 can be held by a practitioner and has a receiving space in which the cartridge 201 can be engaged. And the first electrical contact 291 exposed from the cartridge 201 and the second electrical contact 292 disposed on the handle 202 when the cartridge 201 is coupled to the receiving space have. When the electrical contacts 291 and 292 are coupled to each other, the ultrasonic pulse power from the ultrasonic power supply unit 290 can be supplied to each part embedded in the cartridge 201. [

The cartridge 201 can be freely removed or inserted from the receiving space of the handle 202. The acoustic liquid stored in the cartridge 201 is completely sealed in the cartridge 201, so that the handle 202 does not need to adopt a separate waterproof structure.

The power input unit 270 receives power through a cable extending from the handle 202. The cable may be connected to the control body or a commercial AC power source. The power input unit 270 converts the input external power into a predetermined direct current power.

The oscillator 280 oscillates at a specific high frequency. The high frequency may be, for example, a frequency between several tens of kHz and several MHz.

The ultrasonic power source unit 290 generates ultrasonic pulse power at a specific frequency by controlling the direct current power from the power source input unit 270 using a high frequency from the oscillator 280. [ The generated ultrasonic pulse power can be supplied into the cartridge through the electrical contacts 291 and 292.

The ultrasonic power supply unit 290 generates the first ultrasonic pulse power of 4 to 7 MHz for operating the transducer of the HIFU output unit 210 and outputs the first ultrasonic pulse power of the 20 kHz frequency band for operating the ultrasonic motor 221 2 < / RTI > ultrasonic pulse power. Also, the ultrasonic power source unit 290 may generate the third ultrasonic pulse power of 300 to 500 kHz for operating the high-frequency magnetic-pole unit.

Since the HIFU output unit 210, the ultrasonic motor 221 and the high frequency magnetic pole unit 240 are controlled by the high frequency switching system of the ultrasonic frequency band, the ultrasonic pulse power Can be generated and provided.

The high-frequency stimulation unit 240 applies an electric stimulus to the skin of the subject by the ultrasonic pulse of 300 to 500 kHz. The electrodes of the high frequency stimulation portion 240 may be arranged around the irradiation range of the HIFU output portion 210 (see FIG. 3). High frequency stimulation has the effect of relaxing the muscles and relieving the pain felt by the physician during the procedure using HIFU.

The near-infrared ray output unit 240 may include a near-infrared LED that emits light of a wavelength band of 630 to 830 nm. Near infrared rays are irradiated to the skin of the recipient. The near-infrared rays penetrate deeply into the skin's dermal layer, giving a warm sensation and stimulating collagen. As a result, near infrared rays combine with the skin lifting effect of HIFU, resulting in a synergistic effect of the procedure.

The near infrared ray output unit 240 may be operated by the ultrasonic pulse power provided by the ultrasonic power source unit 290 or may be operated by the DC power source generated by the power source input unit 270. [

In addition, the handle 202 of the handpiece may be provided with a trigger button (see 116 in Fig. 1) that can be manipulated by a practitioner. Ultrasonic pulse power from the ultrasonic power source unit 290, Or the like, to the respective constituent parts of the photoconductive drum 201 simultaneously or selectively.

3 is a view schematically showing the bottom surface of the cartridge. The bottom surface of the cartridge 201 becomes a surface to be brought into contact with the skin of the subject. This bottom surface is formed in a generally long shape and a window of an ultrasonic transmitting material is formed at the center so that the HIFU output from the HIFU output unit 210 can reach the skin. The inside of the window is the internal space of the cartridge and can be filled with acoustic liquid such as distilled water, where the window includes a waterproof function.

High-frequency magnetic poles 231 and 232 constituting the high-frequency magnetic pole portion 240 are disposed around the window. Further, a near-infrared ray emitting LED 242 of a near-infrared ray output portion for irradiating near infrared rays is disposed around the window.

When the HIFU output unit 210 applies the HIFU to the skin of the client, a high frequency stimulus is applied from the high frequency stimulus electrodes 231 and 232 and a near infrared ray is irradiated from the near infrared ray output unit 240, Can be improved.

Figure 4 shows a cross-sectional view of the cartridge of Figure 3 taken along line A-A '. Although one HIFU output unit 210 is illustrated as reciprocally movable in the drawing, a plurality of HIFU output units 210 may be provided. The ultrasonic motor 221 is disposed on one side of the inside of the cartridge 201. The rotational force of the ultrasonic motor 221 rotates the stroke 222 and the moving mechanism 223 moves along the rotating stroke 222. [ Since the HIFU output unit 210 is coupled to the moving mechanism 223, the HIFU can be moved to the skin in the face shape while the HIFU moves according to the movement of the moving mechanism 223.

Figure 5 shows a cross-sectional view of the cartridge of Figure 3 taken along the line B-B '. The coupling relationship between the ultrasonic motor 221, the stroke 222, the movement mechanism 223, and the HIFU output unit 210 can be checked together with FIG.

6 shows power and signaling diagrams of a multifunctional high-intensity focusing type ultrasonic handpiece according to the present invention.

The DC 48V power input block receives a 48V DC voltage from an external power supply such as an SMPS configured on the outside of the handpiece. The input 48V DC voltage can be converted to various voltages such as 12V, 6.5V and 5V and supplied to each part of the handpiece as required.

The RF drive power block boosts the input 48V voltage to DC 120V.

The RF amplification block applies the boosted DC 120V to the HIFU output section, the ultrasonic motor drive section, and the high frequency magnetic pole section. The HIFU output is switched to 4MHz and 7MHz to output the HIFU to the skin of the client. A voltage having a driving frequency of 20 to 100 KHz is applied to the ultrasonic motor driving unit. The rotation speed and the rotation amount of the ultrasonic motor can be controlled by varying the frequency. The operation of the ultrasonic motor causes the HIFU output portion to move horizontally. The high frequency magnetic pole part operates at the driving frequency switched from 300 to 500 KHz.

The ultrasonic motor block includes an ultrasonic motor. Ultrasonic motor is a motor using piezoelectric ceramics piezoelectric effect that generates vibration in response to a change in electric field applied from an ultrasonic motor driving part. It is a motor which has a generating force of 3 Kg.cm, a reaction speed of 0.1 ms, Operation is possible and high torque is generated.

The high-frequency magnetic-field stimulating unit applies a stimulus to the subject's skin by the input high-frequency voltage of 300 to 500 KHz.

The RF OSC and drive block are drivers for high frequency switching and are switchable up to 8 NHz. The switching frequency controls the GATE of the MOSFET disposed at the previous stage of each output terminal of the high-frequency amplifying block.

The CPU and the interface block receive the operator's setting and use operation, and control the operations of the respective parts according to the input operation.

According to the multifunctional high-intensity focusing type ultrasonic handpiece according to the present invention having such a structure, not only the HIFU can be irradiated in the form of a plane but also the high frequency stimulation and / or the near infrared rays can be irradiated to the treatment site, .

In addition, by configuring the driving unit with the ultrasonic motor, the driving unit can be lightweight and miniaturized, and can be embedded in the cartridge. As a result, the HIFU output section, the driving section, the high-frequency magnetic-pole section and the near-infrared ray output section can be built in the cartridge, and only the electrical contact is exposed from the cartridge, so that the waterproof structure of the cartridge can be achieved simply and completely.

In addition, since the ultrasonic power supply unit for driving the HIFU output unit can be used as it is instead of a separate power supply unit for driving the ultrasonic motor, the circuit configuration is simplified and the manufacturing cost can be reduced.

The embodiments of the present invention described above are merely illustrative of the technical idea of the present invention, and the scope of protection of the present invention should be interpreted according to the claims. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the essential characteristics thereof, It is to be understood that the invention is not limited thereto.
