Hereinafter, with reference to FIG. 1 and FIG. 2, each structure of the ultrasonic surgery apparatus which concerns on a present Example is demonstrated.

First, as shown in FIG. 1, the main body 110 may have a spherical shape as a whole and may be formed to protrude one side. A protruding hole may be formed at one protruding side of the main body 110, and the through hole may be a passage through which ultrasonic waves generated from the ultrasonic generator 120 are irradiated to the treatment site. In addition, the side may be gripped by the user, it may be formed in a curved shape that can be rotated to switch the operation mode of the ultrasonic generator 120 to be described later.

In addition, a space in which the ultrasonic generator 120, the touch detection sensor 130, the motion recognition sensor 140, the controller 150, and the battery unit 114 may be formed inside the main body 110 may be formed. In addition, the notification unit 112 may be formed outside.

As shown in FIG. 2, the battery unit 114 may be formed inside the main body 110 to provide electrical energy necessary for the ultrasonic wave generation unit 120 to generate ultrasonic waves. In addition, a charging terminal connected to the battery unit 114 may be formed in the main body 110, and electrical energy may be charged in the battery unit 114 through the charging terminal.

The remaining battery amount may be measured by measuring the voltage of the battery unit 114 using a voltage sensing sensor such as a voltmeter, and the controller 150 may control the notification unit 112 through the remaining battery amount data.

As shown in FIG. 1, the notification unit 112 is formed on the side of the main body 110 to turn on / off the power of the ultrasonic generator 120, an available state of the ultrasonic generator 120, and the battery unit 114. Depending on the amount of battery remaining in the) may be a signal to the user by sound or light.

For example, the notification unit 112 transmits a signal to the user by sound or light, and the operation of the notification unit 112 may be controlled by the controller 150. When the power of the ultrasonic generator 120 is turned on, the controller 150 has a predetermined number of times of ultrasonic irradiation of the ultrasonic generator 120 and a voltage of the battery unit 114 is equal to or less than a predetermined voltage. If so, a signal may be transmitted to notify the user of the current state by voice or light. For example, the notification unit 112 may be configured as an LED lamp and may transmit a signal to the user in various colors to suit each situation.

As shown in FIG. 2, the ultrasonic wave generator 120 is coupled to the through hole inside the main body 110 to generate ultrasonic waves, and irradiates the ultrasonic wave to the treatment site through the through hole formed on the other surface of the main body 110. Can be.

In addition, the ultrasonic generator 120 may be a cartridge having a transducer provided therein to generate focused lesions to generate thermal lesions. Accordingly, the ultrasonic generator 120 may be detachably coupled to the main body 110 to be replaced with another ultrasonic generator 120 after use.

Focused ultrasound can be used for skin lifting or skin tightening procedures by irradiating shallow skin tissues, and can be used for obesity treatment procedures that burn or dissolve and dissolve fat tissue by irradiating focused ultrasound to subcutaneous fat layers.

When the ultrasonic generator 120 irradiates the ultrasonic waves more than a predetermined number of times, the function may be degraded and damaged by the heat generated by the ultrasonic generator 120, and thus, the ultrasonic generator 120 needs to be replaced according to the functional degradation of the ultrasonic generator 120. As described above, the notification unit 112 may signal by sound or light so that the user can check when there is an operation more than a predetermined number of times of the ultrasonic generator 120 by the controller 150, and the user may notify this notification. It can be seen that the replacement time of the ultrasonic generator 120 through.

As shown in FIG. 2, the touch sensor 130 is positioned adjacent to the through hole formed in the main body 110, and detects that the treatment part contacts one surface of the main body 110 where the through hole is located. The contact signal may be transmitted to the controller 150.

In other words, the touch sensor 130 may detect contact between one surface of the main body 110 and the treatment site and transmit contact data as a signal to the controller 150, and the controller 150 generates ultrasonic waves according to the touch data signal. The operation of the unit 120 may be controlled.

As shown in FIG. 2, the motion recognition sensor 140 may be coupled to the inside of the main body 110 to recognize movement of the main body 110 and transmit recognition data as a signal. In addition, the motion recognition sensor 140 may include an acceleration sensor and an angular velocity sensor (gyro sensor), and whether the main body 110 is moved, a moving speed, a moving acceleration, and an angular velocity through the motion recognition sensor 140. , Position, tilt, etc. can be recognized.

As shown in FIG. 2, the controller 150 may be located inside the main body 110 to control the ultrasonic wave generator 120 and the notification unit 112. In detail, the controller 150 receives contact between the main body 110 and the treatment site transmitted by the touch detection sensor 130 and the motion recognition sensor 140, data of movement of the main body 110, and the like to the preset condition. Accordingly, it is possible to control whether the ultrasonic generator 120 operates, the irradiation speed and mode switching of the ultrasonic wave, and the signal generation of the notification unit 112, respectively.

In addition, the control unit 150 may be input to the identification code for the ultrasonic generator 120, the controller 150 is only when the ultrasonic generator 120 is identified by the stored identification code, the ultrasonic generator ( The operation of 120 can be controlled. That is, the controller 150 may identify the identification code assigned to the ultrasonic generator 120 by the identification code preset in the controller 150 so that only the identified ultrasonic generator 120 may generate ultrasonic waves. .

As the ultrasonic generator 120 is identified by the controller 150 as described above, when the ultrasonic generator 120 needs to replace the ultrasonic generator 120 because the ultrasonic generator 120 exceeds the number of available ultrasonic irradiation times, the ultrasonic generator that is not a genuine product is not genuine. 120 may be prevented from being used in combination, and the user may use a genuine ultrasonic generator 120 to provide more stable and reliable ultrasonic waves.

The controller 150 searches the coordinates of the position where the ultrasonic generator 120 irradiates the ultrasonic wave through the motion recognition sensor 140 to prevent continuous ultrasonic irradiation at the position where the ultrasonic wave is already irradiated. Can control the operation.

When the body 110 is irradiated with ultrasonic waves, the procedure cannot be performed properly if the irradiation is made unintentionally several times at the same position, so that the control unit 150 receives the position coordinates at which the ultrasonic waves are irradiated. Irradiation of the ultrasonic wave can be prevented, and multiple irradiation of the same position can be prevented from causing damage to a surgical site such as an image.

Next, a control method of the ultrasonic surgical apparatus will be described with reference to FIG. 3.

According to FIG. 3, when one surface of the main body 110 contacts the surgical site, operating the ultrasonic generator 120, recognizing the movement of the main body 110 using the motion recognition sensor 140, and When the movement of the main body 110 is stopped, there is provided a control method of the ultrasonic surgical apparatus, including the step of stopping the operation of the ultrasonic generator 120.

That is, the ultrasonic treatment apparatus according to the present embodiment is controlled in the automatic mode, and when one surface of the main body 110 contacts the treatment site, the touch sensor 130 detects the touch and operates the ultrasonic generator 120 through the touch. As the user moves the main body 110 along the treatment site, ultrasonic waves may be automatically applied to the treatment site from the ultrasonic generator 120. Then, when the movement of the main body 110 is stopped, the motion recognition sensor 140 may detect this and thereby stop the operation of the ultrasonic generator 120.

In this way, the main body 110 may be in contact with the treatment site, and the power of the ultrasonic generator 120 may be turned on / off through the process of stopping the movement. The face lifting procedure can be safely performed.

In addition, the operation of the ultrasonic generator 120 may be stopped even when the contact between one surface of the main body 110 and the surgical site during the operation of the ultrasonic generator 120 is released.

Accordingly, the ultrasonic wave can be prevented from being unnecessarily irrespective of the non-surgical site, and when the user completes the procedure, the operation of the ultrasonic generator 120 may be stopped by leaving contact at the surgical site without a separate device manipulation.

After one surface of the main body 110 is in contact with the surgical site and the irradiation of the ultrasonic waves is started, the irradiation of the ultrasonic waves may be performed at predetermined intervals. In addition, the irradiation speed of the ultrasonic waves may be related to the moving speed of the main body 110. May be controlled. That is, when the contact portion of the treatment region and the main body 110 is generated by the touch detection sensor 130, the ultrasonic generator 120 operates, and the controller 150 recognizes the motion when the main body 110 moves along the surgical site. The sensor 140 may recognize the moving speed of the main body 110 to adjust the operating speed of the ultrasonic generator 120 according to the moving speed of the main body 110.

More specifically, the controller 150 may increase or decrease the ultrasonic irradiation speed of the ultrasonic generator 120 in proportion to the moving speed of the main body 110 recognized by the motion recognition sensor 140.

Through this, even if the user does not adjust the moving speed of the main body 110 by paying great attention to the procedure, a uniform procedure can be performed at regular intervals, thereby greatly improving the effect of the ultrasound procedure.

On the other hand, after the ultrasonic generator 120 is operated, if the number of times of operation of the ultrasonic generator 120, that is, the number of ultrasonic irradiation is more than a preset number, the notification unit 112 may be activated.

In other words, in order to prevent the ultrasonic wave from being irradiated more than the number of available irradiation times of the ultrasonic wave generation unit 120, the number of times that the ultrasonic wave generation unit 120 operates, that is, the number of ultrasonic irradiation times is counted. The unit 112 may be controlled to signal the user by sound or light.

In addition, the above-described notification unit 112 is controlled to inform the remaining battery in addition to the available state of the ultrasonic generator 120 so that the notification unit 112 is operated when the voltage of the battery unit 114 is less than the predetermined voltage. Can be.

In order to measure the voltage of the battery unit 114, a voltmeter for measuring the voltage of the battery unit 114 may be located inside the main body 110, and the measured voltage data may be transmitted to the controller 150.

When the ultrasonic generator 120 includes an identification code and matches the identification code preset and recognized by the controller 150, the ultrasonic generator 120 may control the ultrasonic generator 120 to irradiate ultrasonic waves.

In detail, the ultrasonic generator 120 may include an identification code physically or electrically embedded therein, and an identification code recognition sensor may be formed to recognize the identification code. When the identification code data is transmitted to the controller 150 and identified by the identification code preset in the controller 150, the controller 150 may control the ultrasonic irradiation of the ultrasonic generator 120.

As described above, the ultrasonic surgical apparatus according to the present embodiment may be driven in the automatic mode by the touch monitoring sensor and the motion recognition sensor 140, but may be switched to the manual mode according to a predetermined condition.

That is, when the motion detected by the motion recognition sensor 140 corresponds to a motion including a preset reference motion, the touch generating sensor 130 and the motion recognition sensor 140 are deactivated to operate the ultrasonic generator 120. The mode can be switched to manual mode.

Such a manual operation mode of the ultrasonic generator 120 is not used in a general situation, but is a so-called hidden mode, and failure or malfunction of the touch sensor 130 occurs, so that irradiation of ultrasonic waves occurs smoothly. Can be implemented or implemented according to user needs.

In the manual mode, for example, the ultrasound may be irradiated once each time the user presses the operation button. In addition, the ultrasound may be set to be irradiated at a predetermined speed and frequency when the user presses the operation button.

The manual mode switching may be performed by rotating the main body 110 above a reference speed value about one axis.

The rotation speed of the main body 110 may be detected by the motion recognition sensor 140, and more specifically, the motion recognition sensor 140 may be configured with respect to each of the x, y, and z axes that are orthogonal to each other as shown in FIG. 1. Rotational components can be recognized. In the present embodiment, when the speed of the rotational movement around the y-axis is greater than or equal to a predetermined reference upper limit value, the operation mode of the ultrasonic generator 120 may be switched to the manual mode by the controller 150.

In this case, when the condition that the rotational speed around the y-axis is equal to or greater than the reference upper limit value and the condition that the rotational speed about the x-axis and the z-axis respectively become less than or equal to the predetermined reference speed value are satisfied together, the ultrasonic wave generator ( The operating mode of 120 may be switched to the manual mode.

The operation mode switching of the ultrasonic generator 120 is made by rotating the main body 110 without pressing a separate button, thereby preventing the mode from being switched by accidentally pressing a button during the procedure.

Recognition of the rotational motion by the motion recognition sensor 140 may be made more precisely based on the following two additional criteria. As described above, since the manual mode is used in an emergency such as a failure of the touch sensor 130, the expression condition needs to be more strictly controlled. Therefore, when all of the following additional conditions are also satisfied, the manual mode of the ultrasonic generator 120 may be used. Can be switched to.

First, the motion recognition sensor 140 may detect whether the rotation of the main body 110 is continuously performed. That is, when the main body 110 is rotated at a constant rotation speed or more for a preset reference time or more after the rotational movement starts, it can be seen that the condition as the rotation for mode switching is satisfied.

When the rotation of the main body 110 is continued, since the main body 110 is shaken about each axis and the rotation occurs, the rotational components for each of the x, y, and z axes change, and thus, the x, y, and z axes If the average value for a predetermined time of the rotation component for each time is extracted and compared with the reference value, and more than that, it can be determined that the rotation of the main body 110 is continued.

In addition, the motion recognition sensor 140 may recognize whether the rotation speed of the main body 110 is reduced after being maintained for a predetermined time, and the controller 150 accordingly controls the operation mode of the ultrasonic generator 120 in a manual mode. You can switch to That is, when the rotation speed is reduced by the motion recognition sensor 140 after the rotation of the main body 110 is maintained for a predetermined reference time or more, the ultrasonic generator 120 determines that the rotational speed is lower than or equal to the predetermined reference lower limit value. The operating mode can be switched.

Rotation of the main body 110 continues, and when the rotational force decreases after a predetermined time, the protruding one side of the main body faces the ground. In order to detect the condition leading to such a state, when the absolute value of the difference between the rotational components for each of the x and y axes is calculated and compared with the reference value, the rotational force of the main body 110 is reduced. You can judge.
