Description

TECHNICAL FIELD [0001] The present invention relates to a HIFU (HIFU) treatment device having a backup function,

The present invention relates to a HIFU operation apparatus having a backup function, and more particularly, to a HIFU operation apparatus having a backup function and, more particularly, A HIFU operation device having a back-up function capable of emitting a high-intensity focused ultrasonic wave of a predetermined size using backup and backed-up data and preventing a cost loss of a user and a cartridge supplier due to replacement or replacement of a failed cartridge .

In general, the HIFU treatment device emits high intensity focused ultrasound (HIFU) to cause a rapid temperature rise in the treatment area. The ultrasonic wave emitted onto the skin does not act on the epidermal layer, Not only induces the coagulation action, but also delivers the deep part of the dermis layer to the heat, thereby promoting the regeneration of collagen, thereby providing the effect of removing wrinkles and improving skin elasticity.

[0003] On the other hand, a conventional HIFU treatment apparatus includes a cartridge mounted with an ultrasonic module that emits a high-intensity focusing ultrasonic wave using a transducer, a handpiece detachably mounted on the cartridge and gripped by a user during operation, And a control module for controlling the timing and drive operation of the ultrasonic waves.

Here, the cartridge has various specifications such as 2MH, 3.5MHz, 4MHz and 7MHz depending on the intensity of the ultrasonic emission of the transducer. As the emission intensity of the ultrasonic wave increases, the position of heat generation inside the skin deepens. The cartridge was replaced with a cartridge having an appropriate standard.

Therefore, the conventional cartridge is equipped with a memory in which cartridge characteristic information such as the number of times of ultrasonic wave emission and the cumulative number of times of emission of ultrasonic waves are stored, including the standard information of the cartridge, and the control module reads data stored in the memory through the handpiece So that an ultrasonic driving signal conforming to the mounted cartridge standard is released and the emitted ultrasonic waves are counted to update and store the accumulated number of ultrasonic wave emissions.

However, since the handpiece is manufactured in a small size so that a practitioner can carry it by hand and a cartridge mounted on one side of the handpiece is also manufactured in a small size, an ultrasonic module for emitting high intensity focused ultrasound waves and a memory device It is necessary to arrange them in close proximity to each other in the cartridge. As a result, electric influences such as electromagnetic waves generated when the high-intensity focused ultrasonic waves are emitted are transmitted to the memory device, and errors or noise are mixed, There is a problem in that the cost of the user and the cartridge supplier is lost due to the replacement or replacement of the cartridge in which the erroneous data is erased or deformed.

For example, when the cartridge has 5,000 times of ultrasonic emission (life expectancy) and 1,000 times of the accumulated number of ultrasonic emissions (the present use amount) at present, error generation or noise is mixed In the case where the cumulative number of ultrasonic emission emissions is changed to 4,000, the user can only receive compensation for about 1,000 times from the cartridge supplier, resulting in cost loss. In the case where the cumulative number of ultrasonic emission emissions is 4,000, the ultrasonic emission When the cumulative count is cleared to 0 or 1,000 cycles are changed, the number of ultrasonic wave emission times is increased by 3,000 ~ 4,000 times, and the time of the user's cartridge is extended. The cartridge supplier compensates the user about 4,000 times when the cartridge is requested to be replaced Cost loss is incurred.

On the other hand, in general, when a resonance frequency in which a hemispherical groove is formed in the lower part of the transducer and matching with the natural frequency is supplied, the transducer can produce ultrasound focused at high intensity by resonance phenomenon.

However, since such a transducer is formed by processing a ceramic material, the hardness and vibration characteristics of the same size are slightly different from each other. Even if the transducer is fabricated in the same standard, the difference in resonance frequency or the output intensity The intensity of the high-intensity focused ultrasonic waves emitted from each transducer is not the same even though the electric input of the voltage (sinusoidal wave) of the same frequency component is applied due to the deviation. In addition, there is a problem that a heat is generated in an area deviating from a desired treatment site due to such a phenomenon, so that the treatment effect is lowered and side effects are generated.

[ And an input terminal 118 for receiving ultrasonic oscillation driving power and applying the ultrasonic oscillation driving power to the transducer 114 is provided.

A through hole 119b is formed in the side surface of the case 111 to be inserted into the handpiece 120 so that the rod 122 of the actuator 121 provided in the handpiece 120 can be inserted therein. And a film-like cover is mounted on the outer side of the output hole 112 to prevent the inner ultrasonic medium from leaking to the outside.

[

In addition, a through hole 127 is formed in the mounting groove 128 to allow the rod 122 provided in the actuator 121 inside to open and close to the outside, and as shown in FIG. 3, 130 is provided with a power supply module 134 for converting a commercial power source applied from the outside into a driving power source necessary for driving the transducer 114 and supplying the converted power.

The control module 130 is a microcontroller for centrally controlling the emission of ultrasonic waves by reading data stored in the memory unit 180. The microcontroller 130 is connected to the cartridge 110 through the handpiece 120, A signal is applied to the ultrasonic module 113, and the number of times of emission of the ultrasonic waves is counted to perform a driving operation for updating and storing the accumulated number of accumulated ultrasonic oscillations.

Referring to FIG. 8, the control module 130 reads the cartridge characteristic information stored in the memory unit 180 and checks whether the cartridge characteristic information stored in the source area is erroneous (S210 (S220). At the time of normal determination, an ultrasonic driving signal conforming to the leading cartridge standard is controlled to be applied to the ultrasonic module 113, and the number of ultrasonic wave emissions is counted to update the accumulated ultrasonic oscillation frequency And stores the same in the source area and the backup area.

On the other hand, when the data error of the source area is determined, the cartridge characteristic information stored in the backup area is backed up to the source area (S251) and the driving operation is performed according to the backed up data (S252).

Here, in order to determine whether the stored cartridge characteristic information is erroneous, the control module 130 compares the sum value of the numbers or bits of the data of the cartridge characteristic information stored in the source area or the backup area with the previously stored checksum reference value, And checks whether the data of the cartridge characteristic information is erroneous by applying a check sum method to judge whether the data is normal or not if it is matched.

When the error check is performed, all the error check target data stored in the memory unit 180 is read and the sum of the data n bytes (Data 1 + Data 2 + Data 3 + ... + Data n_) If the sum of the data n and the field value of the check sum are the same, it is judged as normal, and if it is not the same, it is judged that the error occurs.

For example, when each byte of the error check target data is 10, 20, 30, 12, and 13 as shown in FIG. 9B, the sum value 85 of these bytes is stored in the Check Sum field. byte values are summed and read, and when the sum value and the check sum field value 85 are matched with each other, it is judged that an error occurs if they do not match each other.

In addition, if the data error determination method is used to determine whether data stored in the data error analysis technology has occurred, it may be used in place of the checking method.

2, the control module 130 is provided with a power supply module 134 for converting a commercial power supplied from the outside into a form of driving power required to drive the transducer 114, The control module 130 is connected to the cartridge 110 and the control line L1 through the handpiece 120 to apply a control signal for controlling the ultrasonic emission to the transducer 114. When the transducer 114 is driven by ultrasonic waves The driving power source necessary for emitting the driving current is connected to the cartridge 110 via the power line L2 so that the driving power converted by the power supplying module 134 can be applied to the transducer 114. [ The handpiece 120 may be connected to the console unit 160 having the control module 130 through a cable 161 to receive a driving control signal of the control module 130. [

The control module 130 checks whether the data of the cartridge characteristic information stored in the source area is erroneous each time the driving of the apparatus or the signal line of the cartridge 110 and the control module 130 are reconnected. (Step S240), and if the error is determined, the cartridge characteristic information stored in the source area is backed up in the backup area (S242).

In this way, it is checked whether or not the data of the cartridge characteristic information stored in the source area is erroneous. When normal judgment is made, the data is driven by the stored data of the source area. At the same time, It is possible to automatically manage the data stored in the backup area by backing up the cartridge characteristic information stored in the source area to the backup area so as to provide a condition for using the data in the normal state at the time of data error of the source area.

In addition, the control module 130 checks whether or not the data of the cartridge characteristic information stored in the source area is erroneous. When the error is determined, the control module 130 checks whether the data of the cartridge characteristic information stored in the backup area is erroneous (S230) (S251). When an error is determined, the controller 160 controls the display unit 150 to display an operation error state of the memory unit 180 (S260).

The data storage space of the memory unit 180 in which the cartridge characteristic information of the cartridge 110 is stored is stored in the data storage space of the memory unit 180 according to each configuration and function of the HIFU device 100 according to the preferred embodiment of the present invention, The cartridge characteristic information is divided into a backup area and a backup area to store the same cartridge characteristic information. Whenever the driving of the apparatus or the signal line of the cartridge 110 and the control module 130 is reconnected, It is possible to backup the data stored in the backup area and to use the backed up data to drive the cartridge 110, thereby preventing frequent replacement of the cartridge 110 and providing a more stable operation environment without delaying the operation time.

If both the data stored in the source area and the data stored in the backup area are determined to be erroneous, the operation error state of the memory unit 180 is displayed externally through the display unit 150, It is possible to reduce the time required for checking the memory data error of the cartridge 110 because the cartridge can be replaced.

The HIFU device 100 according to the preferred embodiment of the present invention can be used in a manufacturing process of a transducer of the same standard even if a deviation of the resonance frequency or an output intensity with respect to the input voltage occurs, It is possible to implement an output correction function capable of outputting a high intensity focused ultrasonic wave at the energy intensity set in the standard.

For this, the cartridge characteristic information stored in the memory unit 180 further includes frequency offset correction data and voltage offset correction data according to the measurement result of the output characteristic of the transducer 114, and the control module 130 And reads out the cartridge characteristic information stored in the memory unit 180 by being connected to the cartridge 110 through the handpiece 120. The transducer 114 reads the cartridge characteristic information stored in the memory unit 180 based on the read frequency offset correction data and the voltage offset correction data, (F) and a voltage value (V) of an ultrasonic driving signal to be input to the transducer 114, and outputs the ultrasonic driving signal whose output characteristic is corrected according to the operation signal to the transducer 114.

Here, the ultrasonic driving signal is a signal including a control signal for ultrasonic emission control and a driving power required for the transducer 114 to emit ultrasonic waves. The signal is outputted from the control module 130, To the transducer (114) of the antenna (110). Adjusting the frequency value and the voltage value of the ultrasonic driving signal to be described below may be interpreted as controlling the frequency value and the voltage value of the driving power source included in the ultrasonic driving signal.

The measurement of the output characteristic of the transducer 114 measures the output pattern of the output signal (ultrasonic wave energy intensity) output to the input signal (ultrasonic driving signal) input to the transducer 114, When the deviation of the resonance frequency and the output intensity with respect to the input voltage occurs unintentionally in the process of producing the output signal 114, an output signal value deviating from the output signal value required by each deviation is measured to correct each deviation Is used as basic data for extracting the offset correction data.

In order to calculate the frequency offset correction data and the voltage offset correction data, reference data for determining how much to correct is required. In order to obtain such reference data, there is a variation in the resonance frequency, The measurement device 300 can be obtained by comparing and analyzing the output signal obtained by measuring the reference transducer 114 that has been confirmed to be compared with the output signal of the comparison target transducer 114. As shown in Figure 5, The ultrasonic energy intensity of the transducer 114 can be measured.

5, the measuring apparatus 300 may include a precision scale 310 and an ultrasonic power meter 320. The precision scale 310 may have an accuracy of 0.01 g or less It is preferable to be able to measure the weight by the weight.

The ultrasonic power meter 320 includes a chamber 321 that is seated on the precision scale 310 and upwardly opened and accommodates a medium such as water and the like, And an aluminum target cone 322 arranged so as to be upwardly protruded.

The ultrasonic module 113 is immersed in the medium so as to direct the aluminum target cone 322 in a state where the cartridge 110 is connected to the control module 130 via the handpiece 120, When the ultrasound drive signal is input, the ultrasound module 113 emits ultrasound corresponding to the inputted ultrasound drive signal, which is transmitted to the aluminum target cone 322 via the medium, and a force proportional to the total power of the ultrasound wave is provided .

The weight of the aluminum target cone 322 inside the chamber 321 is changed by the provided force and the change of the weight is measured by the precision scale 310. The gram reading can be converted through separate software and the user can calibrate the ultrasonic wave appropriately while using the wattage reading.

In this way, measurement data can be obtained by measuring the output characteristic of the correction target transducer 114 in the same manner while measuring the output characteristic of the reference transducer 114 and acquiring the reference data.

Also, by repeating the process of measuring the frequency value and the voltage value of the ultrasonic driving signal inputted to the cartridge 110 by gradually changing the manipulated variable by operating the control module 130 and comparing the measured data with the reference data, (Deviation values) and voltage offsets (deviation values) for the ducer 114 can be obtained. In consideration of these offsets, ultrasonic waves having energy intensities set according to the specifications of the transducers 114 can be emitted The frequency offset correction data and the voltage offset correction data for correcting the output characteristics can be extracted.

11 shows an exemplary waveform of the ultrasonic driving signal supplied to the transducer 114. In the figure, f represents the frequency of the ultrasonic driving signal and V represents the voltage of the ultrasonic driving signal.

11, when the reference frequency f of the transducer 114 having the 4 MHz standard is 4 MHz, the reference voltage V is 45 V, and the energy intensity of the predetermined emission ultrasonic wave is 1 J, An ultrasonic driving signal for measurement having a reference frequency value of 4 MHz and a reference voltage value of 45 V is applied to the measurement target transducer 114 to measure the energy intensity of the emitted ultrasonic wave.

If the energy intensity of the measured ultrasonic wave is 0.9 J, a frequency value reduced by 0.1 MHz at the reference frequency and a voltage value reduced by 1 V from the reference voltage value are applied to the measurement target transducer 114, When the ultrasonic oscillation driving power having a frequency value of 3.7 MHz and a voltage value of 42 V is applied, the frequency offset becomes 0.3 MHz and the voltage offset becomes 3 V when the intensity of the measured emission ultrasound is 1 J .

Also, frequency offset correction data of -0.3 and voltage offset correction data of -3 to compensate the corresponding offset value can be extracted according to the acquired frequency offset and voltage offset data, The control module 130 reads -0.3 and -3 and the frequency value of the driving power applied to the corresponding transducer 114 is stored in the reference frequency < RTI ID = 0.0 > The value can be adjusted by decreasing the reference voltage by -3 V and decreasing by -0.3 MHz from the value.

Even if the deviation of the resonance frequency or the output intensity with respect to the input voltage occurs in the process of producing the transducer of the same standard through the correction function of the HIFU device 100 according to the preferred embodiment of the present invention, The output characteristic is corrected by adjusting the frequency value (f) and the voltage value (V) of the ultrasonic driving signal to be input to the transducers according to the degree of deviation of each transducer, So that even if the cartridge is replaced with another cartridge of the same class, the ultrasonic wave of the same energy intensity can be emitted to prevent the skin from being burned due to the excessively discharged energy.

Meanwhile, the HIFU treatment device 100 according to the preferred embodiment of the present invention notifies the user when the transducer 114 is not aligned at the predetermined initial position, thereby preventing skin damage such as an image or scratch And may further include an alignment detection unit 140.

The alignment sensor 140 senses whether or not the ultrasonic module 113 is positioned at the start alignment position P and is mounted on the other end of the body part 116 as shown in FIG. And the ultrasonic module 113 is disposed at the start alignment position P and is disposed opposite to the magnetic body 141 and outputs a sensing signal according to a change in magnetic field due to approach of the magnetic body 141 And a Hall sensor 142 for controlling the Hall effect.

When the medium 110 is filled with a medium such as water to cool the transducer 114 heated by the continuous ultrasonic emission driving, it is possible to detect the starting alignment position P of the transducer 114 A magnetic body 141 made of a magnet material is attached to the upper end of the ultrasonic module 113 equipped with the transducer 114 and the hall sensor 142 is mounted at a position opposite to the mounted magnetic body 141 It is possible to reliably detect the initial alignment position P of the transducer 114 reciprocating within the space in which the medium is filled.
