In general, an ultrasonic wave generator uses a piezoelectric element that generates ultrasonic waves through physical vibration by electrical energy.

If the surgeon is stationary, the movement remains small, or the ultrasound is repeatedly applied to the same site while the ultrasound is generated by the piezoelectric element, the heat generated by the ultrasound may cause burns on the site. It may be. In addition, because the ultrasound is not accurately visualized the area irradiated it is difficult to evenly distribute the ultrasonic energy throughout the treatment area.
또한 초음파 생성 장치에서 생성된 초음파가 피부에 조사되더라도 피부에는 초음파 조사를 감각적으로 느끼지 못하는데 이럴 경우 초음파가 동일한 부위에 조사되어 초음파 생성 장치에서 발생한 열과 초음파 조사로 인해 피부에서 발생되는 열에 의한 화상 위험이 있다.In addition, even if the ultrasonic wave generated by the ultrasonic generator is irradiated to the skin, the skin does not sense the ultrasonic irradiation. In this case, the ultrasonic wave is irradiated to the same area, and there is a risk of burns caused by heat generated by the ultrasonic generator and heat generated by the ultrasonic generator. have.

예를 들어, 도 3에는 초음파 조사 시술 중 디스플레이(41) 상에 가상 이미지(IM)를 표시하고 그 위에 압전소자의 이동 영역을 표시한 한 예가 도시되어 있다. 예를 들어, 시술자는 가상 이미지(IM) 상의 시작점(SP)에 대응하는 실제 피시술자의 신체 부위 상에 초음파 프로브(20)를 위치시키고 환자와 가상 이미지의 방향이 대략 일치되도록 한 상태에서 초음파 조사 시술을 시작하며, 컨트롤러(52)는 모션 센서의 신호를 이용하여 초음파 프로브(20)의 이동 정보를 기초로 초음파 조사 영역을 가상 이미지 상에 표시(도 3에서 점선 및 실선 원으로 표시된 영역)할 수 있다. 이때, 특정 영역에 초음파가 반복 조사된 것으로 판단되는 경우, 모양, 색상 등의 변경을 통해 반복 조사가 표시되도록 할 수 있다.For example, FIG. 3 shows an example in which the virtual image IM is displayed on the display 41 during the ultrasonic irradiation procedure and the moving region of the piezoelectric element is displayed thereon. For example, the operator places the ultrasound probe 20 on the body part of the actual subject corresponding to the starting point SP on the virtual image IM, and the ultrasound irradiation procedure is performed in such a manner that the direction of the virtual image is substantially coincident with the patient. The controller 52 may display the ultrasound irradiation area on the virtual image (area indicated by a dotted line and a solid circle in FIG. 3) based on the movement information of the ultrasound probe 20 using the signal of the motion sensor. have. In this case, when it is determined that the ultrasonic wave is repeatedly irradiated to a specific region, the repeated irradiation may be displayed by changing the shape, color, and the like.

For example, the temperature sensor 65 may be configured to sense the temperature of the space connected to the space in the ultrasonic probe 20 in which the piezoelectric element 21 connected thereto is disposed in the handpiece 10. When the ultrasonic wave is generated, heat is generated in the piezoelectric element 21 and the acoustic matching layer 22. If the generated heat is excessive, the subject may be burned, so that the temperature of the piezoelectric element 21 is detected and the temperature is increased. If it is too high, ultrasonic generation can be stopped. The controller 52 may be connected to the temperature sensor 65 to receive a temperature signal and control the electric pulse generator 51 to stop the ultrasonic generation or to reduce the ultrasonic intensity when the temperature is greater than the preset value.
