Description

초음파 생성 장치ultrasonic generator
본 발명은 초음파를 생성하는 초음파 생성 장치에 관한 것이다.The present invention relates to an ultrasonic wave generating device for generating ultrasonic waves.
초음파 생성 장치를 이용하여 초음파 시술을 할 때 시술자가 초음파 조사 부위를 시각적으로 확인하기 위해서는 직접 눈으로 보거나 별도로 설치되는 소형 카메라를 이용하기도 한다. 특히 최근 비강, 구강 등 체강 내에 삽입 가능한 초음파 장치가 개발되고 있다. 특히 체강 삽입형 초음파 장치에서는 초음파 생성 장치가 체강 내에 삽입되어 사용되기 때문에 시술자가 초음파 조사 부위를 시각적으로 확인하기 더 어렵다. 이를 위해 시술자가 초음파 조사 부위를 시각적으로 확인할 수 있도록 하기 위해 체강에 삽입되는 부분에 소형 카메라를 설치하는 기술이 소개되었다.When performing an ultrasound procedure using an ultrasound generating device, the operator may see the ultrasound irradiation site visually or use a separately installed small camera to visually check the ultrasound irradiation site. In particular, recently, ultrasound devices that can be inserted into body cavities such as the nasal cavity and the oral cavity have been developed. In particular, in the body cavity insertion type ultrasound apparatus, since the ultrasound generating device is inserted into the body cavity and used, it is more difficult for the operator to visually confirm the ultrasound irradiation site. To this end, a technique for installing a small camera in the part inserted into the body cavity was introduced so that the operator can visually check the ultrasound irradiation site.
또한 시각적 확인이 어렵거나 빛이 거의 없는 체강 내에서 영상을 촬영할 수 있도록 하기 위해 조명 장치가 함께 설치된다. 통상 초음파 생성 장치는 하우징 내의 초음파 전달 공간에 설치되는 초음파 압전소자를 포함하며, 초음파의 전파를 위한 초음파 전달 매질이 초음파 전달 공간에 채워지고 초음파 전달 매질의 밀폐를 위한 초음파 투과 필름이 하우징에 설치된다. 초음파 압전소자에 의해 유발된 초음파는 초음파 전달 매질을 통해 전파된 후 초음파 투과 필름을 통과하여 외부로 조사된다. 카메라와 조명 장치는 하우징 내에 또는 초음파 압전소자에 함께 설치될 수 있으며, 이때 조명 장치에 의해 발생된 빛이 초음파 전달 매질을 밀폐하는 초음파 투과 필름에 반사되어 카메라에 비치게 되는 문제가 있다. 또한 조명 장치를 하우징에 고정하기 위해서는 초음파 장치의 크기가 커져야 하는데 만약 체강에 삽입되는 체강 삽입형 초음파 장치의 경우 크기의 확대에 제한이 있다는 문제가 있다. 만약 초음파 장치의 외부적인 크기를 키울 경우에는 체강 삽입 시 환자가 느끼는 이물감, 삽입되는 체강의 해부학적 구조 등으로 인해 문제가 발생하기 때문에, 크기 증가를 제한하기 위해 초음파 압전소자의 크기를 작게 하여 조명 장치를 설치할 공간을 확보하는 방법을 고려할 수 있다. 그러나 초음파 압전소자의 크기의 감소는 초음파 에너지의 부족을 초래하는 문제가 있다.In addition, a lighting device is installed to allow images to be taken in a body cavity where visual confirmation is difficult or there is little light. In general, an ultrasonic wave generating device includes an ultrasonic piezoelectric element installed in an ultrasonic wave transmission space in a housing, an ultrasonic wave transmission medium for propagation of ultrasonic waves is filled in the ultrasonic wave transmission space, and an ultrasonic transmission film for sealing the ultrasonic wave transmission medium is installed in the housing. . The ultrasonic wave induced by the ultrasonic piezoelectric element propagates through the ultrasonic transmission medium and then passes through the ultrasonic transmission film and is irradiated to the outside. The camera and the lighting device may be installed together in the housing or on the ultrasonic piezoelectric element, and in this case, there is a problem in that light generated by the lighting device is reflected by the ultrasonic transmission film sealing the ultrasonic transmission medium and is reflected on the camera. In addition, in order to fix the lighting device to the housing, the size of the ultrasound device needs to be increased. However, if the ultrasound device is inserted into a body cavity, there is a problem in that there is a limitation in size expansion. If the external size of the ultrasound device is increased, problems occur due to the foreign body sensation felt by the patient when inserting the body cavity and the anatomical structure of the body cavity to be inserted. You can consider how to free up space to install the device. However, the reduction in the size of the ultrasonic piezoelectric element has a problem of causing a shortage of ultrasonic energy.
