Description

Ultrasound diagnosis-treatment device using detachable acoustic lens

The present invention relates to an ultrasound diagnosis-treatment apparatus, and to an apparatus that simultaneously enables ultrasound diagnosis and treatment using a detachable acoustic lens.

Compared with the conventional surgical treatment (surgery) or chemotherapy (chemotherapy), non-invasive (non-invasive) and non-traumatic (non-traumatic) treatment using ultrasound is increasingly widely used. In particular, treatment methods such as high-intensity focused ultrasound (HIFU) are generally used to treat (process) living tissues such as cancer, tumors, and lesions.

The treatment method using ultrasound is a method of necrosis of the corresponding living tissue using heat generated by focusing high-intensity ultrasound in one place. At this time, it is necessary to control the high-intensity ultrasound to avoid damaging healthy living tissues, and for this, a device for monitoring the treatment process is required. Since the tissue inside the human body is invisible to the naked eye, the method of checking the state of a living tissue through an ultrasound diagnosis device and treating the corresponding area through an ultrasound treatment device has a problem in that it is difficult to check the treatment site in real time.

Since the ultrasound transmitted to acquire an image of a living tissue inside the human body should not affect the living tissue, conventionally, an ultrasound diagnosis apparatus and a treatment apparatus have been used separately.

In the case of the conventional ultrasound technology for simultaneous treatment and monitoring, since the ultrasound transducer for treatment and the ultrasound transducer for imaging are separately provided and driven, the entire driving system becomes large, the structure is complicated, and separate expensive equipment is required. there was

Accordingly, there is a need for an ultrasound diagnosis-treatment device capable of simultaneously diagnosing and treating with a simple structure.

According to an embodiment of the present invention, the plurality of ultrasonic output elements of the ultrasonic output unit 110 may be divided into a treatment unit element and an image unit element group according to a lens shape of the lens unit 130 to be attached according to a required condition. can

In general, ultrasonic transducers apply a piezoelectric effect or a magnetostrictive effect to convert AC energy of 20 KHz or more into mechanical vibration of the same frequency. For example, the transducer may have a structure including a body with an open side and a piezoelectric element, the inside of the body is filled with air, and a wire for applying a voltage to each piezoelectric element is connected to the structure. The piezoelectric element uses a material causing a piezoelectric effect, such as quartz and tourmaline, and the transducer can generate and output ultrasonic waves using the piezoelectric effect of the piezoelectric element. The structure of such a transducer is merely exemplary, and is not limited to a specific structure or effect. The piezoelectric element of the transducer adjusts the output according to the area to be treated and the purpose, thereby outputting ultrasonic waves of appropriate intensity, and the output ultrasonic waves overlap to form an ultrasonic beam.

For example, before the acoustic lens 131 is attached, the ultrasound output unit 110 that outputs ultrasound for imaging or ultrasound for treatment may be configured as one array ultrasound transducer. The piezoelectric element of one array ultrasound transducer may be divided into two groups: an image unit element and a treatment unit element.

The imaging device may detect a reflected or scattered wave from a tissue in the living body of the diagnostic area (①), and acquire a signal-processed image through the diagnostic control unit 120-1.

In the ultrasound output unit 110 , the treatment unit element for treatment and the imaging unit element for diagnosis may be changed according to the control of the yin-yang frequency, output, etc. of the controller for the plurality of ultrasound output elements. The treatment control unit and the diagnosis control unit may also be disposed in different forms, or may be divided into separate functional blocks in software as described above, but may be executed in the same hardware processor. The positions of the control unit and the device and the diagnosis and treatment areas are not limited as shown in FIG. 2, and various modifications are possible.

It has been described that the present invention provides an ultrasound diagnosis-treatment device capable of simultaneously performing diagnosis and treatment by applying a detachable acoustic lens to a conventional commercially available ultrasound device for diagnosis or treatment.

In various modified examples of the present invention, the acoustic lens 131 is mounted on only one end of the ultrasound output unit 110 or is manufactured in an asymmetrical shape, so that the ultrasound beam can be focused on a portion deviating from the center in the left or right direction. . In addition, when the acoustic lens 131 is manufactured in a symmetrical or asymmetrical shape, the entire acoustic lens 131 may be made of one and the same material, and for each part of the acoustic lens 131 , for example, the lenses at both ends are It can be fabricated using different materials. The acoustic lens 131 may be made of two or more different materials for each part. In this case, since the refractive index and the like vary depending on the material constituting the lens, the focus area of the ultrasound beam may be designed to vary depending on the material constituting the lens as well as the haze and thickness of the lens. That is, the shape, thickness, mounting method, lens material, etc. of the acoustic lens may be variously modified according to various requirements such as a treatment area and a treatment range.

As shown in FIGS. 5A to 5D , it can be seen that the shape and focusing position of the ultrasound beam are changed by the acoustic lenses of various shapes. An acoustic lens of a specific shape according to required conditions, such as a region to be treated, is attached to a partial region of one transducer, for example, a treatment unit element region to output an ultrasonic beam for treatment, and simultaneously passes through the remaining image unit element region. monitoring can be performed.

As described above, the ultrasound diagnosis-treatment apparatus 100 focuses, disperses, or focuses the sound to one array transducer by simply attaching or detaching an acoustic lens of a suitable shape according to the application range to one array transducer. and dispersion.
