1 to 4 show an ultrasonic and low-frequency handpiece 1 according to one embodiment.

Low frequency refers to frequency waves below 1,000 Hz, and mid-frequency refers to frequency waves between 1,000 Hz and 100,000 Hz. In the following description, low-mid frequency may mean a frequency wavelength that includes both low-frequency frequency wavelengths and mid-frequency frequency wavelengths. For convenience of explanation, low-frequency may be used to include low-mid frequencies.

The detachable ultrasonic and low-frequency handpiece (hereinafter referred to as 'handpiece') (1) includes a main body (10), an ultrasonic generator (20), a mid- to low-frequency transmission unit (30), a signal generator (40), and a control unit (50). ) may include.

Although not shown in FIGS. 1 to 10, the handpiece 1 may further include a power supply unit (not shown) to apply power to the signal generator 40, the control unit 50, etc. For example, the signal generator 40 may receive power from a power supply unit (not shown) and generate a frequency signal.

The main body 10 may have a space inside. All or part of the ultrasonic generator 20, the mid-to-low frequency transmission unit 30, the signal generator 40, and the control unit 50 may be accommodated or combined in the internal space provided in the main body 10.

The main body 10 is located on one side of the first housing 110 and the first housing 110 where the ultrasonic generation unit 20 and the mid-to-low frequency transmission unit 30 are coupled, and the second housing is extended to have a length. It may include a housing 120. The second housing 120 may be a part that the operator or user holds when using the handpiece 1.

Hereinafter, for convenience of explanation, the longitudinal direction of the second housing 120 is referred to as the z-axis direction, and the direction in which the ultrasonic generator 20 and the low-mid frequency transmitting unit 30 are coupled is referred to as the coupling axis direction. In one embodiment, the coupling axis direction may be perpendicular to the z-axis direction. That is, the coupling axis direction may be any axis that exists on the xy plane in the Cartesian coordinate system.

The ultrasonic generator 20 may be formed in a cylindrical shape. At this time, the height direction of the cylinder shape may be the coupling axis direction. The ultrasonic generator 20 may be coupled to the main body 10 in the direction of the coupling axis so that one end is interpolated into the main body 10 and the other end is exposed to the outside of the main body 10 .

The signal generator 40 may be accommodated inside the main body 10 . The low-mid frequency transmission unit 30 may be detachably coupled to the main body 10.

The signal generator 40 may be accommodated inside the second housing 120 . The mid-to-low frequency transmission unit 30 may be coupled to the first housing 110 in the direction of the coupling axis so as to be detachable.

The ultrasonic generator 20 may receive a frequency signal from the signal generator 40 and transmit the ultrasonic waves to the subject's skin. The mid-to-low frequency transmission unit 30 can receive a frequency signal from the signal generator 40 and transmit the mid-to-low frequency to the subject's skin.

In one embodiment, the control unit 50 transmits a frequency signal to one of the ultrasonic generator 20 and the low-mid frequency transmission unit 30 based on whether the low-mid frequency transmission unit 30 is coupled to the main body 10. The signal generator 40 can be controlled to selectively apply the signal to .

Specifically, the process by which the control unit 50 recognizes whether the mid-to-low frequency transmission unit 30 is coupled to the main body 10 will be described in detail. The main body 10 may include a sensor module 150 including a sensor PCB 151 and a sensor pin 152. The low-mid frequency transmission unit 30 may include one or more pogo pins 360. When the mid-to-low frequency transmission unit 30 is coupled to the main body 10, the pogo pin 360 penetrates the pogo pin hole 102 formed in the coupling axis direction on the main body 10 in the coupling axis direction, and the sensor pin ( 152). The sensor PCB 151 may recognize that the pogo pin 360 is in contact with the sensor pin 152 and transmit the recognition result to the control unit 50. At this time, the control unit 50 may control the signal generator 40 to apply a frequency signal to the mid-to-low frequency transmission unit 30. The signal generator 40 can apply the frequency signal only to the low-to-mid frequency transmission unit 30. Conversely, the sensor PCB 151 may recognize that the pogo pin 360 is not in contact with the sensor pin 152 and transmit the recognition result to the control unit 50. At this time, the control unit 50 may control the signal generator 40 to apply a frequency signal to the ultrasonic generator 20. The signal generator 40 may apply a frequency signal only to the ultrasonic generator 20.

In another embodiment, the control unit 50 applies a frequency signal only to the ultrasonic generator 20 based on whether the mid- to low-frequency transmission unit 30 is coupled to the main body 10, or applies the frequency signal to the ultrasonic generator ( The signal generator 40 can be controlled to apply to both the 20) and the mid-to-low frequency transmission unit 30. Unlike the above-described embodiment, when the low-mid frequency transmission unit 30 is coupled to the main body 10, the control unit 50 applies a frequency signal to both the ultrasonic generator 20 and the low-mid frequency transmission unit 30. The signal generator 40 is controlled to do so, and when the mid-to-low frequency transmission unit 30 is not coupled to the main body 10 (when detached), the control unit 50 applies the frequency signal only to the ultrasonic generator 20. The signal generator 40 can be controlled to do so.

The signal generator 40 may include an ultrasonic wire 410 and a mid-to-low frequency wire 420. For example, the signal generator 40 includes an ultrasonic wiring 410 that applies a frequency signal to the ultrasonic generator 20 under the control of the control unit 50, and a frequency signal that applies the frequency signal to the ultrasonic generator 20 under the control of the control unit 50. It may include a mid- to low-frequency wiring 420 applied to the low-frequency transmission unit 30. Meanwhile, the signal generator 40 may further include a sensor wire 430, and the sensor wire 430 is electrically connected to the above-described sensor PCB so that the mid-to-low frequency transmission unit 30 is connected to the main body 10. You can sense whether it is connected or not.

The main body 10 may include a connection member 130 disposed on one side to cover at least a portion of the circumference of the ultrasonic generator 20. When the ultrasonic generator 20 is formed in a cylindrical shape, the connecting member 130 may be disposed around one side of the ultrasonic generator 20 to cover a portion of the height of the cylindrical shape.

The connecting member 130 may be formed of a metal material. Additionally, the first housing 110 may be formed of a plastic material. For example, the connecting member 130 may be made of aluminum. As the connection member 130 is made of a metal material, when the ultrasonic generator 20 or the low-mid frequency transmitter 30 transmits ultrasonic waves or low-mid frequency waves to the subject's skin, the frequency and low-mid frequency waveform are maintained uniformly over time. Changes in amplitude can be minimized.

The connecting member 130 and the first housing 110 may be produced by combining them simultaneously during injection molding. In other words, the connecting member 130 and the first housing 110 may be insert-molded. Through insert injection, it is possible to achieve integration of the first housing 110 and the connecting member 130 and to reduce the weight of production.

The mid-to-low frequency transmission unit 30 may have an opening 301 formed in the center. The ultrasonic generator 20 may be coupled to one side of the main body 10 so as to penetrate the opening 301. When the ultrasonic generator 20 has a cylindrical shape, the opening 301 may have a circular shape. Specifically, the ultrasonic wave generator 20 is coupled to one side of the main body 10 so as to penetrate the opening 301, and the mid- to low-frequency transmission unit 30 receives the ultrasonic wave generator 20 through the opening 301. It may be coupled to the connection member 130 of the main body 10 so as to do so. The mechanism by which the mid-to-low frequency transmission unit 30 is coupled to the connection member 130 will be described later.

The low-mid frequency transmitting unit 30 may include a contact member 320 that directly contacts the skin of the subject and a support cover 330 that supports the contact member 320. The contact member 320 coupled to the support cover 330 may be formed such that a portion exposed to the outside of the support cover 330 has a hemispherical shape. In this case, a wire receiving groove 321 may be formed inside the contact member 320 along the center of the hemisphere.

The wire receiving groove 321 may be formed to accommodate one end of the low-to-mid frequency wire 420. The mid-to-low frequency wiring 420 is electrically connected to the contact member 320 and can transmit a frequency signal to the contact member 320. Specifically, the low-to-mid frequency transmission unit 30 may further include a conductor plate 331. The conductor plate 331 is electrically connected to the low-mid frequency wiring 420 and may further include a low-mid frequency oscillator (not shown) that converts the frequency signal received from the low-mid frequency wiring 420 into low-mid frequency.

Figure 4 is a front view of the handpiece 1 viewed in the direction of the coupling axis.

A plurality of contact members 320 may be arranged along the perimeter of the opening 301. Referring to FIG. 4 , it can be seen that a plurality of contact members 320 are arranged at equal intervals along the circumference of the opening 301. In Figure 4, when the opening 301 has a circular shape, 12 contact members 320 are shown arranged at equal intervals along the circumference of the opening 301, but the contact members 320 of the opening 301 and the ultrasonic generator 20 are shown. The shape, arrangement, and number of contact members 320 are not limited thereto.

The connecting member 130 may include a first groove 131 formed along the circumference. The low-mid frequency transmission unit 30 may include a coupling module 310 that is fitted into the first groove 131 when coupled to the main body 10.

The coupling module 310 includes a fitting member 311 that is at least partially fitted into the first groove 131 and a first elastic member 312 that presses the fitting member 311 in a direction toward the first groove 131. It can be included. For example, the first elastic member 312 may be a torsion spring. A torsion spring is a torsion spring that responds to torsional stress.

A plurality of first elastic members 312 and fitting members 311 may be arranged along the perimeter of the opening 301. In Figure 11, three first elastic members 312 and three fitting members 311 corresponding to each of the first elastic members 312 are disposed in the upper, left, and right directions (up and down in the z-axis direction) of the opening 301. (referred to as , the pogo pin 360 is coupled in the lower direction) is shown in an exploded view, but the arrangement of the first elastic member 312 and the fitting member is not limited thereto.

In one embodiment, one end of the first elastic member 312 is received and fixed in the fixing groove 332 on the rear side of the support cover 330, and the other end of the first elastic member 312 is connected to the fitting member 311. Pressure can be applied in the direction toward the first groove 131. Specifically, the other end of the first elastic member 312 may press the fitting member 311 in the coupling axis direction.

In order to perform this mechanism, one end of the first elastic member 312, which is a torsion spring, is formed in a direction perpendicular to the coupling axis direction, and the other end of the first elastic member 312 may be formed in the coupling axis direction. .

Meanwhile, the first groove 131 may be a V-shaped concave groove. Additionally, the bottom of the fitting member 311 fitted into the first groove 131 may be formed to have a V-shape similar to the concave groove of the first groove 131. Accordingly, the fitting member 311 can be accurately fitted into the first groove 131. In addition, even when the mid-to-low frequency transmission unit 30 is detached, the fitting member 311 may slide along the inclined surface of the first groove 131 and the fitting may be released, so that the elastic force of the first elastic member 312 is also maintained. The mid-to-low frequency transmission unit 30 can be easily attached and detached.

The mid- to low-frequency transmission unit 30 may further include a fixing member 340 that extends to have a length in the shape of a rod. The main body 10, specifically the first housing 110, includes a through hole 101 for accommodating the fixing member 340 and a fixing module 140 for fixing the fixing member 340 penetrating the through hole 101. may include.

The low-mid frequency transmission unit 30 may further include a fastening cover 350 that accommodates the coupling module 310. Additionally, the fixing member 340 may be located between the two pogo pins 360. The fastening cover 350 may be coupled with a pogo pin 360.

The fastening cover 350 may further include a receiving bracket (not shown) that accommodates the fixing member 340. The receiving bracket (not shown) may be formed to accommodate at least a portion of the fixing member 340 so that the fixing member 340 is coupled to the fastening cover 350. That is, at least a portion of the fixing member 340 may be coupled to the fastening cover 350.

The fixing member 340 may have a groove 341 formed along the circumference at one end. Here, the end may mean an end opposite to at least a portion of the fixing member 340 coupled to the fastening cover 350.

The fixing module 140 may include a pressing member 141, a ball member 142, a second elastic member 143, and a ball fixing cap 144.

The pressing member 141 is formed to have a length in one direction and can accommodate a part of the fixing member 340, including one end.

The pressing member 141 may further include a ball receiving groove 1411 that accommodates the ball member 142. When the low-mid frequency transmission unit 30 is coupled to the main body 10, the bottom of the ball member 142 accommodated in the ball receiving groove 1411 may be seated in the groove 341 of the fixing member 340. At this time, the ball member 142, the bottom of which is seated in the groove 341, may be fixed by the ball fixing cap 144. Specifically, a convex groove 1441 is formed in the ball fixing cap 144, and the ball member 142 can be fixed by the convex groove 1441. Accordingly, the ball member 142 is pressed in the coupling axis direction by the ball fixing cap 144 until pressing pressure is applied to the pressing member 141, thereby fixing the fixing member 340. As a result, the ball fixing cap 144 can use the ball member 142 to fix the pressing member 141 so that the low-to-mid frequency transmission unit 30 is coupled to the main body 10.

The pressing member 141 may further include an elastic member receiving groove 1412. The second elastic member 143 may be formed to surround one side of the pressing member 141 and provide elastic force to the pressing member 141. Specifically, the second elastic member 143 may be accommodated in the elastic member receiving groove 1412 and formed to surround the elastic member receiving groove 1412.

The pressing member 141 may further include a pressing member cap 1413 that is coupled to one end of the pressing member 141 and to which a force is applied by the user. The outer diameter of the pressing member cap 1413 may be formed to have a smaller diameter than the inner diameter of the ball retaining cap 144. When a pressing force in the coupling axis direction is applied to the pressing member cap 1413, the pressing member cap 1413 is interpolated so that at least a portion is accommodated within the ball fixing cap 144 to compress the second elastic member 143. By doing this, elastic force can be provided to the second elastic member 143. At this time, the range in which the pressing member cap 1413 can be interpolated into the inside of the ball fixing cap 144 may be the pressing range 1414.

At the same time, as the pressing member 141 and the ball member 142 move in the direction of the force, the ball member 142 may come out of the boundary of the iron groove 1441 of the ball fixing cap 144. As the ball member 142 deviates from the area other than the iron groove 1441 of the ball fixing cap 144, the fixing member 340 becomes free to move in the direction of the coupling axis, so that the mid-low frequency transmission unit 30 is connected to the main body part. It can be detached at (10).

As such, the present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. .

Specific implementations described in the embodiments are examples and do not limit the scope of the embodiments in any way. Additionally, if there is no specific mention such as “essential,” “important,” etc., it may not be a necessary component for the application of the present invention.
