Description

Portable HIFU skincare device {PORTABLE HIGH INTENSITY FOCUSED ULTRASONIC SKIN CARE DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to skin care devices using ultrasound, and in particular, to a device related technology that promotes skin cosmetic and therapeutic treatment using High Intensity Focused Ultrasonic (HIFU).

HIFU devices are characterized by direct heating to the human body using powerful focused ultrasound. Conventionally, HIFU devices are known to treat cancers such as liver cancer, uterine cancer, and breast cancer by focusing ultrasound at high intensity (more than 1000W / cm2 of focused area) on one focal point and necrosing or ablation of tumor tissue. . The treatment method using HIFU equipment is a non-invasive method and the demand is increasing due to the recognition that the patient recovers faster and is safer than the surgical method.

Ultrasound is not harmful when passing through human tissue, but the high-intensity ultrasound that forms a focal point generates enough energy to cause necrosis regardless of the type of tissue. The HIFU device is important to focus high intensity energy at the target focus of the body through the linear / rotational motion of the ultrasonic transducer, which converts electrical energy into mechanical vibration energy in the ultrasonic frequency range, and therefore requires precise movement control of the transducer. Do. The focal length, the accuracy of the focal position, the irradiation time and the temperature in the focal region are also important factors. And research and technology on these factors have been much developed.

HIFU technology as described above has been applied to various applications. It is used not only for the treatment of tumor tissues, but also for the purpose of skin care such as wrinkle improvement and obesity treatment. For example, Patent Document 1 below discloses a HIFU surgical handpiece used by connecting to an equipment main body.

However, the HIFU procedure handpiece of Patent Document 1 is used in connection with expensive equipment used in a hospital, and there is a problem in that it cannot be used because it is supplied with power for applying high-intensity ultrasound to the skin of the subject. . Therefore, the operator had to suffer the inconvenience of going to the hospital with such equipment.

In addition, the motor is installed outside the cartridge to drive the transducer inside the structure to increase the power consumption, heat dissipation measures are difficult due to the heat generated by the motor drive.

The inventors of the present invention have completed the present invention after research and efforts for a very long time in order to solve such a problem and the development of technology.

By explaining the operation of the power button 101 and the step button 103 and how the display 105 is displayed in accordance with the battery status, the function and operation of the present invention can be understood. Therefore, this will be described in detail by way of example.

As described above, when the power button 101 is pressed for 0.5 seconds or more, the device is booted and a status indicator is turned on through the display 105 with a buzzer sound. Preferably, lighting the status display when the power is turned on causes the number of shots available to the user to be displayed.

In the present invention, 1SHOT refers to an ultrasonic irradiation event in which the motor moves back to the origin by moving the 10mm distance at a 1mm interval period during the ultrasonic irradiation operation mounted on the cartridge 200, and "SHOT number" refers to such high-intensity ultrasonic waves. The number of events investigated. When the power button 101 is pressed for a few seconds (for example, 3 seconds) while the power is on, the power is turned off while changing to a power off state display with a buzzer sound.

When the battery inside the main body 100 is discharged, the battery icon on the display 105 is displayed to indicate that the battery is discharged, and a buzzer sound is emitted every few seconds to warn the user to charge.

The cartridge 200 incorporating the HIFU transducer is mounted and detached from the lower receptacle of the head portion of the main body 100 as shown. When the cartridge 200 is inserted into the body head accommodating part, the connector terminal 210 of the cartridge 200 makes electrical contact with the body connector part. The cartridge 200 stores distilled water which serves as a medium for high-intensity focused ultrasound irradiation, and also cools the superheat phenomenon that may be generated. Therefore, the distilled water inlet 205 is installed on the surface of the cartridge 200 is connected to the sealed distilled water tank (not shown).

With the cartridge 200 mounted on the head of the main body 100, the cartridge 200 may be coupled to the cradle 300 for charging and placing the portable HIFU skincare device. The head of the cartridge 200 is inserted into the mounting groove 310 of the cradle 300. Then, while the UV lamp (not shown) built in the mounting groove 310 is turned on, the head of the cartridge 200 is disinfected with UV, and the battery inside the main body 100 is charged through the cradle charging terminal 307. (The cradle charging terminal 307 is electrically connected to the main body charging terminal 107 of FIG. 3). At that time, the charging state is displayed through the display 105 of the main body 100.

The portable HIFU skincare device 1 does not operate until the cradle 300 and the main body 100 are separated from each other in a coupled state.

3 is a view of the main body 100 and the cartridge 200 viewed from the opposite direction to FIG. 2. The cartridge 200 is mounted through the opening of the head receiving portion 109 of the main body 100. Then, the cartridge connector terminal portion 210 shown in FIG. 2 and the connector terminal portion 110 of the main body form an electrical contact so that the controller of the main body can control the internal module of the cartridge.

On the other hand, the user can remove the cartridge 200 from the main body 100 by pressing the cartridge replacement button (212).

Figure 4 shows the configuration of the cartridge 200 in a preferred embodiment of the present invention in three directions in three directions. Fig. 4C is the back side.

The PCB 250 of the cartridge 200 is provided with a control unit including internal electronic elements (not shown), and the cartridge connector terminal unit 210 is exposed to the outside. The PCB 250 is installed in the rear protrusion 240 outside the cartridge 200 housing. The rear projection 240 is formed to protrude from the rear surface of the cartridge 200, the receiving groove (not shown) as the thickness of the PCB 250 is provided so that the PCB 250 is fitted. Then, the PCB 250 is mounted in the accommodation groove of the rear protrusion 240. And a cable electrically connected to the PCB 250 is connected to the transducer transport mechanism device located inside the housing.

Two chambers are installed in a direction opposite to the rear surface of the cartridge 200. The first chamber 291 and the second chamber 292 are in communication with each other, and serves as a tank for receiving distilled water. The first chamber 291 is provided with a transducer transport mechanism device including a piezo motor 216. The transducer transport mechanism device includes a transporter and a transporter module, which will be described later.

The second chamber 292, whose outer front surface is the acting portion, projects toward the front side with a narrower width than the first chamber 291. This protruding surface becomes a working part and is in surface contact with the object. The housing of the HIFU transducer is located in the second chamber 292.

A sealing member 207 is inserted into an inlet corresponding to the rear protrusion of the first chamber 291 so as to prevent distilled water contained in the chambers 291 and 292 from leaking out.

FIG. 5 is an exploded perspective view showing the center portion of the cartridge 200 of FIG. 4 after being cut in the front direction from the back, and FIG. 6 is a cross-sectional view of the separated perspective view of FIG.

5 and 6, it is possible to easily grasp the configuration inside the cartridge 200 and the installation method and the location of the sealing member 207. In addition, the configuration of the back protrusion 204 and the PCB 250 can be accurately understood.

The distilled water inlet 205 is preferably a small hole because distilled water is introduced using a syringe, and more precisely, a nut that can be opened and closed by using a bolt having a diameter of about 1 to 3 mm is provided. In addition, it is preferable that the waterproof rubber 205a is fitted into the distilled water inlet 205.

In addition, it is preferable that six fastening nuts 206 are installed to couple the rear housing with the front housing (only half of the cartridge 200 housing is shown in FIG. 5, so only three fastening nuts 206 are visible).

The ultrasonic transducer 201 is coupled to the transport module 211. Therefore, the position of the ultrasonic transducer 201 is changed as the conveyor module 211 moves. At the upper end of the feeder module 211, the feeder 202 is installed on a carbon shaft connected to the piezo motor 216 by the feeder fixing rubber 214 and the feeder module fixing part 217. The transfer sensor 213 detects the transfer position.

When the piezo motor 216 is driven, the transporter 202 is displaced to a predetermined position, whereby the position of the ultrasonic transducer 201 is determined. On the other hand, the high-intensity ultrasonic wave irradiated toward the object from the ultrasonic transducer 201 passes through the window 203 installed in the center of the working part, and the ultrasonic wave transmitting film such as polyimide or polymethylpentene is provided in the window 203. Can be used.

7 exemplarily illustrates the relationship between the piezo motor 216 and the transporter 202 according to one preferred embodiment of the present invention. 7 (a) is a state in which the transporter 202 is installed on the carbon shaft 215 having the piezo motor 216 installed at one end thereof, and FIG. 7 (b) is a view for better understanding of the internal configuration of the transporter 202. 7 (c) shows a planar configuration of the transporter 202 in a state where each member is engaged, in a state where the members are separated.

In the embodiment of the present invention, the center of the transporter 202 has a structure through which the carbon shaft 215 which linearly transmits the displacement sent by the piezo motor 216 to the transporter 202 passes. That is, the center of the conveyer 202 is composed of holes through which the carbon shaft 215 passes. Based on this hole, the bodies of the transporter 202 can be separated from each other in two pieces as shown, and are also fitted to each other and installed on the carbon shaft 215.

The pair of carrier pieces are provided with convex transporter fixing guides 202a and concave transporter fixing holes 202b, respectively. The transporter fixing guide 202a of the first transporter piece is fitted into the transporter fixing hole 202b of the second transporter piece. Similarly, the transporter fixing guide 202a of the second transporter piece is inserted into the transporter fixing hole 202b of the first transporter piece so that each transporter piece is combined to form one transporter 202. At this time, in order to form a circular recess in the center of the front and rear ends of the conveyor, the body of each carrier piece is provided with a recess having a semicircular cross section. Then, the conveyor fixing rubber 214 is fitted into the recessed portion, so that the integrated coupling of the conveyor 202 is completed.

Through the above configuration, a mechanism for linearly moving the ultrasonic transducer 201 in the cartridge 200 of the present invention is completed. Let's look at Figure 8.

When the ultrasonic transducer 201 starts operation, the ultrasonic transducer 201 is linearly transferred from the initial position of FIG. 8 (a) to the positions of FIGS. 8 (b) and 8 (c). When the piezo motor 216 is driven, the ultrasonic transducer 201 moves by 1 mm through the carbon shaft 215. Then, the position of the ultrasonic focus F generated by the ultrasonic transducer 201 is also changed, and thus the ultrasonic focus region formed on the object is also changed. The high-intensity focused ultrasound is thus irradiated and the skin beauty effect is achieved by changing the position of the ultrasonic focus F.

As shown in FIG. 9, the focal point F at which the high-intensity ultrasound beams irradiated through the ultrasound transducer 201 focuses only on the ultrasound focal region S1 of the skin layer S of the object. In the present invention, it can be set to irradiate a total of 10 ultrasonic waves, especially during 1Shot. Irradiation is performed once per 1 mm, and each time 1 mm is moved by driving the motor, a focal region of 10 mm is formed during 1 shot.

That is, high-intensity ultrasound is applied only to the skin region of the ultrasound focal region S1, for example, a wound is caused by heat of 65 to 100 ° C. Thus, by stimulating the skin tissue, by allowing the human body to respond naturally to the stimulation, it is possible to improve the skin elasticity as well as wrinkles. On the other hand, due to the principle of high-intensity ultrasonic focusing, no scar is left on the epidermis of the object in contact with the window of the ultrasonic transducer 201.
