Description

A probe head having a non-contact infrared temperature measuring device, a high intensity focused ultrasound device including the head, and an automatic ultrasound output control method using the device TECHNICAL FIELD and automatic ultrasonic output control method using the device}

The present invention relates to a probe head having a non-contact infrared thermometer, a high-intensity focused ultrasound device including the head, and an automatic ultrasound output control method using the device, and more particularly, to a variety of conditions such as tonsillitis, sore throat, rhinitis, and skin cancer. A far-infrared thermometer is mounted on the probe head of a high-intensity focused ultrasound device used to treat superficial diseases, scar tissue, spots, wrinkles, etc. It relates to a technology that can effectively treat the affected tissue while minimizing thermal damage.

High Intensity Focused Ultrasound (High Intensity Focused Ultrasound) device mainly generates high-frequency (2~10MHz) ultrasound with a hemispherical or semi-cylindrical piezoelectric element, focuses water as a delivery medium to the mechanical focus, and irradiates it to the affected area to make a living body It is a device that enables a non-invasive procedure by coagulating the tissue due to the heat generated by the molecular vibration of the tissue.

On the other hand, when the ultrasonic wave in this region passes through the tissue, it destroys and solidifies the tissue by a mechanical effect, a cavitation effect, a thermal effect, etc. If irradiated continuously above the thermal equilibrium critical energy, the temperature rises to about 56-80℃ in the area of about 0.5-3 mm (diameter) × 2-15 mm (depth) of tissue, and coagulant necrosis due to protein coagulation inside the cell , and tissue necrosis occurs as much as the entire volume of ultrasound irradiation, and the coagulated and necrotic tissue is slowly decomposed and absorbed in the human body over a period of several weeks to several months, and new cell regeneration takes place to treat the lesion.

The coagulation of the tissue by the high-intensity focused ultrasound varies according to the focal shape of the ultrasonic wave generating piezoelectric element, the intensity of acoustic energy applied to the tissue, and the applied frequency. , the higher the applied frequency, the smaller the size of the focusing focal point, the faster the temperature rises and the faster the tissue coagulation.

In a procedure using such a High Intensity Focused Ultrasound device, how much energy intensity and time to irradiate ultrasound energy to the desired focal depth depends on the location of the treated tissue to minimize thermal damage to normal tissues other than the lesion. In addition to being an important factor in this process, it should be able to coagulate by applying sufficient ultrasonic energy to the lesion tissue.

However, in the prior art, after determining the reference output using the phantom, which is a human body model, it has been used by adjusting the output energy to a value obtained by adjusting variables based on the clinical data of biological tissue treatment.

However, in this conventional technique, it is difficult to reflect all the types and characteristics of various lesion tissues, and it is difficult to measure the actual temperature of the treated tissue site where the temperature changes rapidly in effective and safe high-intensity focused ultrasound treatment. In many cases, it relied on the operator's intuitive judgment as to whether

Conventional high-intensity focused ultrasound (HIFU) devices use high-frequency ultrasound energy for the procedure by using the in-house standard output value of the equipment according to the affected part or by controlling the power according to the user's clinical experience. The result of the procedure was easy to depend on, and it was difficult to quantify the degree of temperature rise at the focus of the high-intensity focused ultrasound (HIFU) probe and the degree of tissue coagulation. has a

In addition, in the prior art, after treating the affected part (focusing part), it is inevitably accompanied by the inconvenience of having to provide a separate temperature measuring device to measure the temperature, which takes a lot of time for the procedure, while the procedure depends entirely on the skill of the therapist. There is bound to be a huge difference in time.

The front waterproof film 60 is configured on the upper part of the case 10 to protect the front surface of the ultrasonic piezoelectric element 40 and to prevent the inflow when coolant is leaked, and through the acquisition pipe 51 When the supplied cooling water moves to the water outlet pipe 55 while passing through the cooling water tank portion of the ultrasonic piezoelectric element 40, it is prevented from leaking to the outside of the front surface of the probe 1 to effectively form the focused ultrasonic energy. It is also possible to prevent the influx of external substances into the cooling water tank. And the front waterproof film 60 may be used a material that passes infrared rays generated from the affected part well, and a transparent material may be used as an embodiment thereof.

It can be applied to all types for fixing the mold angle, freely extensible head, and changing the angle of the head for narrow space.

On the other hand, as shown in FIG. 7, the configuration of the high intensity focused ultrasound apparatus including the probe head of the present invention operates by receiving power from a battery or an external power source, and supplies power and cooling water to the probe 1, a generator (5) that checks information on the operation of the probe (1) on a display and enables selective control of the probe (1); It operates by receiving power and cooling water from the generator 5, but consists of a probe 1 having the probe head 3 at the end, and a wiring part 7 connecting the generator 5 and the probe 1 do.

Here, the generator 5, as shown in FIG. 2, controls 0.8~10 MHz high-frequency ultrasonic oscillation, external input/output, and ultrasonic output power by the temperature measurement value measured from the temperature measuring device 30 of the probe 1 It is configured to control the control, automatic ultrasonic pulse train, measure the degree of tissue degeneration in the focal area by detecting A-Mode signals, and control the cooling water circulation pump and heat exchanger.

Looking at the automatic ultrasound output control method using the high-intensity focused ultrasound apparatus, when ultrasound output is applied to the probe 1 under the control of the generator 5, the living body to be coagulated located at the focus of the probe 1 The tissue temperature is continuously measured as a non-contact infrared temperature, but when the temperature of the living tissue reaches the upper tissue coagulation temperature set in the generator (5), the ultrasonic output is automatically stopped or the ultrasonic pulse train cycle is changed to cause excessive heat to the living tissue. Prevents damage and transmits and receives ultrasound with a single hollow hemispherical piezoelectric element, emits the A-Mode signal and the ultrasound output before ultrasound output is applied to the focal area to coagulate the tissue Measure and analyze the difference in amplitude and interval to measure the degree of tissue coagulation in the depth direction.

In addition, as shown in FIG. 8, after analyzing the coagulation depth of the biological tissue by comparing the signal waveform of the probe focus part before and after coagulation of the biological tissue, the degree of thermal denaturation on the X-Y plane is measured through the thermometer of the probe. After measuring and analyzing the degree of tissue thermal degeneration in the depth direction, which is the Z-axis, by using the A-Mode signal, an effective treatment is possible by selectively controlling the ultrasound output using the analyzed data.

If the ultrasonic output is precisely controlled, side effects such as necrosis and perforation due to excessive heat damage to the biological tissue of the affected part (focus part) can be minimized.

In other words, when the state of protein and water inside the living tissue is in a normal state and when it is solidified with high-power focused ultrasound output, the physical properties are different and affect the transmission speed and attenuation coefficient of ultrasonic acoustic energy, so this change is a signal At this time, before the HIFU ultrasound output is applied to the focal area, it transmits a weak output ultrasound signal, receives the ultrasound signal reflected while passing through the tissue, converts it into an A-Mode signal, measures it, and proceeds to the next step for treatment. If the HIFU ultrasound output is emitted to solidify the tissue, and then the A-Mode signal is measured and compared again, the degree of tissue thermal degeneration in the depth direction can be identified. It can help you decide whether to change the survey location. Through the control method of the present invention, when performing or treating various skin diseases, it is possible to improve the safety of the procedure by more optimal irradiation of ultrasound energy, and to improve the overall speed of the procedure or treatment.
