More specifically, a plurality of transducers are individually mounted on an ultrasonic radiation frame by transducer holders, and at least a part of the ultrasonic radiation frame is made of an insulating material, and the present invention relates to a high-intensity focused ultrasound generating device using an insulating material that can improve durability and insulation.

Background Art

[0002] Generally, a high-intensity focused ultrasound (HIFU) generating device focuses ultrasonic waves generated from a transducer to generate high-intensity ultrasonic energy, and irradiates this to the affected part of a patient to raise the temperature of the affected part, thereby enabling treatment of the affected part without surgery.

[0003] When using dozens or hundreds of transducers in a conventional high-intensity focused ultrasound generating device, after mounting a large number of transducers on the front surface of an ultrasonic radiation frame, the entire front surface of the ultrasonic radiation frame is coated with glue to form a waterproof layer, thereby fixing a large number of transducers with the waterproof layer and preventing water leakage.

[0004] However, since ultrasonic energy generated forward from the transducer is absorbed by the waterproof layer, there is not only a problem that the input voltage has to be increased to compensate for this, but also a problem that the ultrasonic radiation frame has to be replaced even if only one of the large number of transducers fails.

Mode for Carrying Out the Invention

[0038] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings as follows.

[0039] A high-intensity focused ultrasound generating device using an insulating material according to an embodiment of the present invention is a device using high-intensity focused ultrasound (HIFU). The high-intensity focused ultrasound generating device includes a transducer array in which dozens or hundreds of transducers are radially arranged, and can not only treat the affected part of a patient with a tumor or the like, but also stimulate the brain to treat Alzheimer's disease, depression, etc., and can also apply heat to a specific site to enhance immunity.

[0040] FIG. 1 is a perspective view showing a head module of a high-intensity focused ultrasound generating device according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view showing a coupling structure between an ultrasonic radiation frame and a transducer holder according to a first embodiment of the present invention.

[0041] Referring to FIGS. 1 and 2, the head module of the high-intensity focused ultrasound generating device includes an ultrasonic radiation frame 10, a plurality of transducers 20, and a plurality of transducer holders 100.

[0042] The ultrasonic radiation frame 10 is made of an insulating material. That is, the ultrasonic radiation frame 10 can be formed only of resin, or can also be formed of a carbon composite material of an insulating material in which a carbon material is mixed with the resin at a preset ratio. Here, the resin includes, for example, at least one of polyamide resin, acetal resin, polycarbonate, and polyphenylene oxide. The carbon material includes, for example, carbon fiber, carbon nanotube, Graphite, graphene, etc. The preset ratio is a ratio set to limit the addition of the carbon material so that the carbon composite material does not have conductivity. The preset ratio can be preset through experiments and the like.

[0043] The ultrasonic radiation frame 10 has a probe 11 coupled to the center of the front surface 10a, and a plurality of coupling holes 12 are radially arranged around the probe 11. The ultrasonic radiation frame 10 is formed in a dish shape with a concave front surface so that ultrasonic waves radiated from the plurality of transducers 20 can be focused and radiated to one place.

[0044] The plurality of coupling holes 12 are through holes formed at a predetermined interval from each other. The number of the coupling holes 12 is set according to the number of the transducers 20.

[0045] The plurality of transducers 20 can include piezoelectric elements. When voltage is applied, the transducer 20 generates ultrasonic waves. Taking the example that the transducer 20 is formed in a disc shape, dozens or hundreds of the transducers 20 are radially arranged to form a transducer array. The number of the transducers 20 can be set according to the ultrasonic energy to be radiated.

[0046] Each surface of the transducer 20 is coated with an electrode material that is a conductive material. That is, each of the transducers 20 is made of a piezoelectric element material inside and coated with an electrode material on the surface.

[0047] Taking the example that the transducer holder 100 is formed to have electrical conductivity, in this embodiment, taking the example that the transducer holder 100 is molded from a non-conductive material and then each surface is coated with a conductive material. Taking the example that the transducer holder 100 is molded from a resin material and the surface is coated with the conductive material. Also, the transducer holder 100 can be coated with a conductive material only on the surface excluding the inside of the head portion 110 described later or the support protrusion 110b described later. When the entire surface of the transducer holder 100 is coated with the conductive material, at least a part of the side surface and the back surface of the transducer 20 is coated with a non-conductive material to prevent short circuits. Further, when at least a part of the side surface and the back surface of the transducer 20 is coated with a waterproof material, corrosion due to water intrusion and fluctuation of the output value can be prevented.

[0048] Taking the example that the conductive material includes at least one of chromium, nickel, cadmium, iron, copper, platinum, gold, silver, lead, and alloys. However, it is not limited thereto, and any material having electrical conductivity can be applied.

[0049] In this embodiment, an example will be given to describe that a chromium coating layer is formed on the surface of the transducer holder 100 to form the electrode 170.

[0050] The transducer holder 100 is detachably coupled to each of the plurality of coupling holes 12. The transducer 20 is coupled to the transducer holder 100, respectively.

[0051] Referring to FIGS. 3 to 6, the transducer holder 100 includes a head portion 110 in which a seating groove 110a into which the transducer 20 is inserted and seated is formed, and a body portion 120 that extends rearward of the head portion 110 and is coupled to the coupling hole 12.

[0052] The head portion 110 is formed to have a diameter larger than that of the coupling hole 12 so as to be seated on the front surface 10a of the ultrasonic radiation frame 10. The head portion 110 is formed with the seating groove 110a, support protrusions 110b, locking protrusions 110c, and an opening 110d.

[0053] The seating groove 110a is formed such that the front surface opens forward of the head portion 110 and is a groove formed so that the transducer 20 can be seated.

[0054] The support protrusion 110b is formed to protrude forward from the bottom surface of the seating groove 110a at a predetermined height and is a step formed to support the lower surface of the transducer 20. The support protrusion 110b forms a separation space S between the lower surface of the transducer 20 and the bottom surface of the seating groove 110a, and forms a passage through which the electrode wire 180 coupled to the transducer 20 passes, so that not only can the structure of the electrode be stably implemented, but also the vibration of the transducer 20 can be enabled and the vibration wave energy of the transducer 20 can be maximized. The support protrusion 110b is formed of a plurality and will be described by taking as an example that they are formed to be separated from each other at a predetermined interval. However, it is not limited thereto, and the support protrusion 110b may be provided singly at the center of the bottom surface of the seating groove 110a. Also, the support protrusion 110b may be integrally formed with the head portion 110, and it is of course possible to form it by applying a non-conductive material, such as glue, to the bottom surface of the seating groove 110a.

[0055] The locking protrusion 110c protrudes from the bottom surface of the seating groove 110a and is formed such that the tip is bent inward, and can prevent the transducer 20 inserted into the seating groove 110a from detaching. The tip of the locking protrusion 110c can be changed as long as it is a shape that can prevent the detachment of the transducer 20, such as a hook shape. The locking protrusions 110c are formed such that a plurality are separated from each other at a predetermined interval. In the present embodiment, the description will be given by taking as an example that some of the plurality of locking protrusions 110c protrude from the support protrusion 110b.

[0056] The opening 110d is a portion formed to be cut and opened on the side surface of the seating groove 110a. The opening 110d has the advantage of facilitating assembly. Also, the opening 110d enables the transducer 20 to vibrate inside the seating groove 110a and maximizes the vibration wave energy of the transducer 20.

[0057] The body portion 120 preferably extends rearward from the head portion 110 and is formed to penetrate through the coupling hole 12. The body portion 120 is formed smaller in diameter than the head portion 110. A current supply hole is formed at the center of the body portion 120 so that a current supply portion described later passes through it.

[0058] The body portion 120 includes a shaft portion 121 and a screw portion 122.

[0059] The shaft portion 121 extends rearward from the head portion 110 and is formed in a cylindrical shape so as to be press-fitted into the coupling hole 12.

[0060] The screw portion 122 extends rearward from the shaft portion 121, and a thread is formed on the outer peripheral surface so as to be fastened by a fastening member 150.

[0061] The fastening member 150 is preferably a nut, but is not limited thereto.

[0062] On the other hand, FIG. 3 is a cross-sectional view showing a coupling structure between the ultrasonic radiation frame and the transducer holder according to the first embodiment of the present invention.

[0063] The adhesive member will be described by taking a flexible glue as an example. A flexible glue layer 200 made of the flexible glue is formed between at least one of the back surface and the side surface of the transducer 20 and the head portion 110. As the flexible glue, silicon or epoxy-based glue can be used, and any flexible material can be applied.

[0064] In this embodiment, the flexible glue layer 200 will be described by taking as an example the case where it is formed between the back surface of the transducer 20 and the support protrusion 110b. However, it is not limited thereto, and the flexible glue layer 200 can also be formed between the side surface of the transducer 20 and the inner surface of the locking protrusion 110c. That is, as long as the front surface of the transducer 20 is not blocked, the flexible glue layer 200 can be applied at any position.

[0065] Since the transducer 20 is adhered and fixed to the transducer holder 100 by the flexible glue, the position of the transducer 20 is fixed inside the transducer holder 100 while the transducer 20 can vibrate, so that the loss of vibration wave energy of the transducer 20 can be minimized. Also, since no glue is applied to the front surface of the transducer 20, the loss of ultrasonic energy radiated forward from the transducer 20 can be prevented. That is, the flexible glue layer 200 is formed only on the back surface or the side surface of the transducer 20 and does not cover the front surface of the transducer 20, so there is no restriction on the radiation of ultrasonic energy through the front surface.

[0066] Also, between the transducer holder 100 and the ultrasonic radiation frame 10 is sealed by a sealing member.

[0067] The sealing member includes a first sealing member 210 that seals between the head portion 110 of the transducer holder 100 and the front surface 10a of the ultrasonic radiation frame 10, and a second sealing member 220 that seals between the body portion 120 and the back surface 10b of the ultrasonic radiation frame 10.

[0068] The first sealing member 210 will be described by taking as an example two first and second O-rings 211 and 212 that are inserted and coupled to the back surface of the head portion 110. However, it is not limited thereto, and the number of the first sealing members 210 can be variously changed and applied. Further, the first sealing member 210 is made of various materials such as silicon and rubber in addition to the O-ring, and any structure that can perform sealing can be applied.

[0069] The first O-ring 211 and the second O-ring 212 are preferably formed to have different diameters from each other. The first O-ring 211 and the second O-ring 212 are inserted into a ring-shaped groove 110e formed on the back surface of the head portion 110 and are in close contact with the front surface 10a of the ultrasonic radiation frame 10 to perform sealing.

[0070] The second sealing member 220 includes a third O-ring 221 that is externally inserted into the shaft portion 121 of the body portion 120, and an O-ring pressing member 222 that is externally inserted into the shaft portion 121 from behind the third O-ring 221 and brings the third O-ring 221 into close contact with the back surface 10b of the ultrasonic radiation frame 10.

[0071] The O-ring pressing member 222 is formed in a ring shape, and an inclined surface 222a is formed on the front surface so that a part of the third O-ring 221 is seated thereon.

[0072] The second sealing member 220 may further include a washer 223 provided between the O-ring pressing member 222 and the fastening member 150. The washer 223 is not an essential component of the second sealing member 220 and can be additionally included. The washer 223 can seal the third O-ring 221 and the O-ring pressing member 222 and serve to hold the transducer holder 100.

[0073] The second sealing member 220 is made of various materials such as silicon and rubber in addition to O-rings and washers, and any of them can be applied as long as it has a sealing structure.

[0074] Also, a waterproof glue layer 250 is formed by waterproof glue between the electrode wire hole 120a of the transducer holder 100 and the electrode wire 180 described later. The same waterproof glue as the flexible glue can be used. Furthermore, it is of course possible that the waterproof glue layer 250 is formed so as to completely fill the separation space S with the waterproof glue.

[0075] On the other hand, referring to FIG. 4, the structure of the electrode using the transducer holder 100 will be described as follows.

[0076] The surface of the transducer holder 100 is coated with a conductive material to form an electrode 170, and the inside of the transducer holder 100 is formed of a non-conductive material.

[0077] The electrode 170 is a coating layer formed by coating the entire surface of the transducer holder 100 with the conductive material and is grounded. However, it is not limited thereto, and of course, the electrode 170 may be formed by coating only a part of the surface of the transducer holder 100 including the portion in contact with the transducer 20 with the conductive material. Also, the entire surface of the transducer holder 100 may be coated with a conductive material, and only the surface excluding the inside of the head portion 110 or the support protrusion 110b can be coated with a conductive material. When the entire surface of the transducer holder 100 is coated with the conductive material, at least a part of the side surface and the back surface of the transducer 20 is coated with a non-conductive material to prevent short circuits. Furthermore, if at least a part of the side surface and the back surface of the transducer 20 is coated with a waterproof material, corrosion due to water intrusion and fluctuation of the output value can be prevented.

[0078] Any of the conductive materials can be applied as long as they can be used as electrodes, such as metals like silver. The non-conductive material will be described by taking a plastic material as an example.

[0079] Therefore, the front and side surfaces of the transducer 20 are in contact with the electrode 170 and grounded, and a current supply unit is connected to the back surface of the transducer 20.

[0080] The current supply unit will be described by taking the electrode wire 180 as an example. However, it is not limited to this, and any device that can supply current, such as pins and connectors, can be applied.

[0081] The electrode wire 180 is soldered to the center of the back surface of the transducer 20 and is an electric wire for supplying current to the transducer 20.

[0082] The electrode wire 180 is arranged to pass through the current supply hole of the transducer holder 100. The current supply hole will be described by taking the electrode wire hole 120a formed so that the electrode wire 180 can pass through as an example.

[0083] The electrode wire 180 is drawn out to the rear of the ultrasonic radiation frame 10 through the electrode wire hole 120a and connected to a separate circuit board.

[0084] Here, the electrode 170 is set to one of the positive electrode and the negative electrode, and the electrode wire 180 is set to the remaining one of the positive electrode and the negative electrode, so that a current can flow through the transducer 20 due to the potential difference applied to the electrode 170 and the electrode wire 180. For example, it is also possible that the electrode 170 is the positive electrode and the electrode wire 170 is set to the ground electrode, and of course, it is also possible that the electrode 170 is the ground electrode and the electrode wire 180 is set to the positive electrode.

[0085] The transducer 20 is seated on the support protrusion 110b, and the separation space S is formed between the transducer 20 and the bottom surface of the seating groove 110a of the transducer holder 100, thereby preventing the electrode wire 180 from contacting the electrode 170 which is the surface of the transducer holder 100, so that no short circuit occurs.

[0086] Therefore, since it is not necessary to solder the electrode wire to the front surface of the transducer 20, the occurrence of water leakage due to the soldering structure on the front surface of the transducer 20 can be prevented. That is, it is possible to prevent water leakage from occurring inside from the front surface of the transducer 20 which is exposed on the front surface of the ultrasonic radiation frame 10 and contacts the liquid.

[0087] Also, since it is not necessary to solder the electrode wire to the front surface of the transducer 20, there is an advantage that the structure of the electrode is simplified and damage to the transducer 20 can be prevented.

[0088] Furthermore, in the high-intensity focused ultrasonic generating device configured as described above, a plurality of transducers 20 are mounted on the ultrasonic radiation frame 10 using the transducer holder 100, and the space between the transducer 20 and the transducer holder 100 is adhered and sealed with the flexible glue, so that even if not all of the glue is applied to the front surface of the ultrasonic radiation frame 10, it is possible to prevent water leakage from occurring inside from the front surface of the ultrasonic radiation frame 10.

[0089] Also, since not all of the glue is applied to the front surface of the ultrasonic radiation frame 10, it is possible to prevent loss of ultrasonic energy radiated forward from the transducer 20 with the entire front surface of the transducer 20 being exposed. When the front surface of the transducer 20 is blocked by a glue layer as in the prior art, there is a problem that ultrasonic energy is absorbed by the glue layer, but in the present invention, since the entire front surface of the transducer 20 is exposed, this can be prevented.

[0090] Furthermore, inside the transducer holder 100, between it and the transducer 20, the position of the transducer 20 is fixed by being adhered with the flexible group to prevent gaps while allowing the transducer 20 to vibrate. Therefore, the loss of vibration wave energy of the transducer 20 can be reduced.

[0091] Also, since the plurality of transducers 20 are individually mounted via the transducer holder 100, and the transducer holder 100 is detachably coupled to the ultrasonic radiation frame 10, there is an advantage that the transducers 20 can be individually repaired and replaced.

[0092] Furthermore, since the plurality of transducers 20 are individually mounted via the transducer holder 100, there is an advantage that at least a part of the capacities of the plurality of transducers 20 can be configured to be different. For example, it is also possible to increase the capacity of the transducer arranged on the central side of the ultrasonic radiation frame 10, and of course, it is also possible to control the voltages applied to the plurality of transducers 20 to be different from each other.

[0093] Also, between the transducer holder 100 and the ultrasonic radiation frame 10, by being sealed with a sealing member such as an O-ring, not only can water leakage from the front to the rear of the ultrasonic radiation frame 10 be prevented, but also there is an advantage that the transducer holder can be easily attached to and detached from the ultrasonic radiation frame.

[0094] On the one hand, in the above embodiment, the description was given by taking as an example that all of the transducers 20 were coupled to the coupling holes 12 of the ultrasonic radiation frame 10. However, the present invention is not limited to this, and it is of course possible to provide the transducers 20 only in at least a part of the coupling holes 12 according to the capacity of the high-intensity focused ultrasound generating device. When the transducers 20 are provided only in at least a part of the coupling holes 12, the transducer holder 100 is coupled to the entire coupling holes 12, and a holder cover (not shown) for shielding the opened front surface is detachably coupled to a part of the transducer holder to which the transducers 20 are not coupled. The holder cover (not shown) is made of a material different from that of the transducers 20, is formed in the same shape, and can be coupled by glue. Therefore, the number of mounted transducers 20 can be adjusted, and the energy capacity of the high-intensity focused ultrasound generating device can be adjusted.

[0095] Also, in the above embodiment, since the ultrasonic radiation frame 10 is made of an insulating material such as resin or carbon composite material, the insulation of the ultrasonic radiation frame 10 can be ensured. Further, since there is no need to perform an additional operation so that the ultrasonic radiation frame and the transducer holder do not come into contact with each other, the number of steps is reduced and the cost can also be reduced.

[0096] Also, when the ultrasonic radiation frame 10 is formed of resin or carbon composite material, precise molding is possible, the moldability can be improved, and there is an advantage that the weight and volume of the ultrasonic radiation frame 10 can be reduced as compared with the case of manufacturing with other materials such as metal. When reducing the weight of the ultrasonic radiation frame 10, the durability of the device for assembling the ultrasonic radiation frame 10 can also be improved.

[0097] Furthermore, by using a material with strong processability and impact resistance such as polyamide resin, acetal resin, polycarbonate, polyphenylene oxide, etc. for the insulating material, corrosion resistance, wear resistance, etc. can also be ensured.

[0098] On the other hand, FIG. 7 is a diagram showing the structure of an electrode using a transducer holder according to the second embodiment of the present invention.

[0099] Referring to FIG. 7, the structure of the electrode using the transducer holder according to the second embodiment of the present invention is different from that of the first embodiment in that the entire transducer holder 300 is formed of a conductive material as the electrode, and the other remaining configurations and operations are the same as those of the first embodiment. Therefore, a detailed description of similar configurations will be omitted, and the description will focus on the differences.

[0100] The transducer holder 300 is formed of the conductive material and is the electrode itself, and the structure and shape are applied to the first embodiment.

[0101] Any conductive material such as a metal like silver that can be used as an electrode is applicable.

[0102] The front and side surfaces of the transducer 20 are in contact with the electrode and grounded, and an electrode wire 180 is connected to the back surface of the transducer 20.

[0103] The electrode wire 180 is soldered and joined to the center of the back surface of the transducer 20 and is an electric wire for supplying current to the transducer 20. The electrode wire 180 is arranged to pass through the electrode wire hole 120a of the transducer holder 100. The electrode wire 180 is drawn out behind the ultrasonic radiation frame 10 through the electrode wire hole 120a and connected to a separate circuit board.

[0104] Here, the transducer holder 300, that is, the electrode, is set to be either the positive electrode or the negative electrode, and the electrode wire 180 is set to be the remaining one of the positive electrode and the negative electrode, and a potential difference applied to the electrode and the electrode wire 180 can cause current to flow through the transducer 20. Also, it is of course possible that the electrode is set to be the ground electrode and the electrode wire 180 is set to be the positive electrode.

[0105] The transducer 20 is seated on the support protrusion 110b, and the separation space S is formed between the transducer 20 and the bottom surface of the seating groove of the transducer holder 100, thereby preventing the electrode wire 180 from contacting the surface of the transducer holder 300, so that no short circuit occurs. Also, the support protrusion 110b can be coated with a non-conductive material or formed of a non-conductive material.

[0106] Therefore, since there is no need to solder the electrode wire to the front surface of the transducer 20, it is possible to prevent the occurrence of water leakage due to the soldering structure on the front surface of the transducer 20. That is, it is possible to prevent water leakage from occurring inside from the front surface of the transducer 20 that is exposed on the front surface of the ultrasonic radiation frame 10 and contacts the liquid.

[0107] Also, since there is no need to solder the electrode wire to the front surface of the transducer 20, there is an advantage that the structure of the electrode is simplified and damage to the transducer 20 can be prevented. Further, at least a part of the side surface and the back surface of the transducer 20 can be coated with a non-conductive material to prevent a short circuit. Also, at least a part of the side surface and the back surface of the transducer 20 can be coated with a waterproof material to prevent corrosion due to water intrusion or a phenomenon in which the output value fluctuates.

[0108] On the one hand, the high-intensity focused ultrasound generating apparatus according to the third embodiment of the present invention is different from the first and second embodiments in that the ultrasonic radiation frame 10 includes a frame main body (not shown) formed of metal and an insulating layer (not shown) formed by anodizing the surface of the frame main body. The remaining configurations and operations are the same as those of the first and second embodiments. Therefore, the following detailed descriptions of similar configurations are omitted, and the different points will be described in detail.

[0109] Here, the metal will be described by taking aluminum as an example.

[0110] Since the insulating layer (not shown) is an oxide film generated by anodizing the aluminum, not only the insulating function of the ultrasonic radiation frame 10 but also the corrosion resistance and wear resistance can be improved.

[0111] The insulating layer (not shown) can be generated to a thickness equal to or greater than a preset thickness. The preset thickness is set to a thickness through which current does not pass.

[0112] On the other hand, without being limited to the above embodiment, the frame main body (not shown) of the ultrasonic radiation frame 10 can also be formed of a material lighter than metal, and the insulating layer (not shown) can be a coating layer formed by coating the surface of the frame main body with an insulating material.

[0113] On the one hand, FIG. 8 is a rear view showing an ultrasonic radiation frame and an RF board according to the fourth embodiment of the present invention. FIG. 9 is a cross-sectional view taken along line A-A of FIG. 8.

[0114] Referring to FIGS. 8 and 9, the high-intensity focused ultrasound generator according to the fourth embodiment of the present invention is provided in the ultrasonic radiation frame 10, and the plurality of transducers 20 are electrically connected thereto respectively. Different from the first, second, and third embodiments, it further includes an RF board 260 that supplies RF power to the transducer 20. Since the remaining configurations and operations are similar, hereinafter, the description will focus on the different configurations, and the detailed details of the similar configurations will be omitted.

[0115] The transducer holder 100 and the transducer 20 are an integrated electrode that are in contact with each other and electrically connected. The electrode is connected to the RF board 260 and receives the application of RF power.

[0116] Taking the example that the transducer holder 100 is connected to the negative electrode of the RF board 260 and grounded, and the transducer 20 is connected to the positive electrode of the RF board 260 and receives the application of RF power for explanation.

[0117] The transducer holder 100 and the transducer 20 are respectively connected to the board connector 261 of the RF board 260 via the electrode wire.

[0118] The electrode wire includes a first electrode wire (not shown) that connects the transducer holder 100 and the board connector 261, and a second electrode wire 180 that connects the transducer 20 and the board connector 261.

[0119] The second electrode wire 180 is soldered and coupled to the center of the back surface of the transducer 20, and is an electric wire for supplying RF power to the transducer 20. The second electrode wire 180 is arranged to pass through the electrode wire hole 120a of the transducer holder 100. The second electrode wire 180 is drawn out to the rear of the ultrasonic radiation frame 10 through the electrode wire hole 120a and connected to the RF board 260.

[0120] The RF board 260 is detachably coupled to the back surface of the ultrasonic emission frame 10, and is connected to a plurality of first electrode lines (not shown) respectively connected to the plurality of transducer holders 100 and a plurality of second electrode lines 180 respectively connected to the plurality of transducers 20.

[0121] The RF board 260 is disposed in the remaining portion excluding the center so as to prevent interference with the probe 11 when the probe 11 is coupled behind the ultrasonic emission frame 10. Also, the RF board 260 can be composed of a plurality. In this embodiment, the RF board 260 will be described by taking an example in which four are each arc-shaped and are connected to each other to form a ring shape. When the RF board 260 is composed of a plurality, it is also possible to connect to each other, and of course, it is also possible to arrange them so as to be separated from each other by a predetermined interval. Also, the number and shape of the RF board 260 can be variously changed as long as the shape can prevent interference with the probe 11. That is, the RF board 260 can be variously changed as long as it is arranged in the remaining portion excluding the central portion which is the coupling portion where the probe 11 is coupled by the ultrasonic emission frame 10. For example, one or more RF boards 260 can be arranged in a shape such as a square, a triangle, and a semi-circular shape in the remaining portion excluding the central portion of the ultrasonic emission frame 10.

[0122] Also, when the RF board 260 is composed of n pieces, the plurality of transducers 20 can be classified into n bundles according to the position, and the plurality of transducers 20 can be respectively connected to the n RF boards 260 for each bundle. Therefore, it becomes possible to individually replace and repair the RF board 260.

[0123] The RF board 260 is provided with a plurality of board connectors 261.

[0124] The board connector 261 is a connector provided on the RF board 260 to which the first and second electrode lines 180 are detachably coupled. The board connector 261 is formed to correspond to the number of the transducers 20 so that the transducers 20 are independently connected. However, it is not limited thereto, and at least two or more transducers 20 may be coupled to one board connector 261, and it is of course possible that the number of the board connectors 261 is larger than the number of the transducers 20. Also, the board connector 261 may be integrally provided on the RF board 260, or may be detachably coupled to the RF board 260.

[0125] The RF board 260 further includes a monitoring sensor (not shown).

[0126] The monitoring sensor (not shown) is a sensor provided on the RF board 260 for independently monitoring the operating state of the transducer 20. In this embodiment, the monitoring sensor (not shown) will be described by taking as an example the case where it senses the power supply state of the second electrode line 180 connected to each of the transducers 20 and senses the normal operation or abnormal operation of the transducer 20. For example, the monitoring sensor (not shown) will be described by taking as an example the case where it is a current sensor or a voltage sensor that senses overcurrent or overvoltage or current interruption of the electrode line 180. However, it is not limited thereto, and any sensor that can sense the abnormal state of the temperature sensor or the transducer 20 is applicable.

[0127] An insulating cover 270 is provided on the outer surface of the RF board 260.

[0128] The insulating cover 270 is provided to cover the outer surface of the RF board 260 and serves to insulate. In this embodiment, the insulating cover 270 is described by taking a polyimide film as an example, but it is not limited thereto, and any material that can be insulated can be applied. The insulating cover 270 can also be coupled to the RF board 260 using a fastening member or the like, and can also be attached to the RF board 260 using a separate adhesive member.

[0129] On the other hand, the RF board 260 is connected to a power supply device (not shown) for supplying the RF power.

[0130] The RF board 260 and the power supply device (not shown) can be connected to a plurality of power cables (not shown) detachably coupled to the RF board 260. The power cable (not shown) is described by taking a BNC (Bayonet Neil-Concelman) cable provided with a BNC connector as an example, but it is not limited thereto and can be applied in various ways.

[0131] As described above, in this embodiment, the transducer 20 is connected to the RF board 260 and receives the application of the RF power through the RF board 260.

[0132] By connecting the plurality of transducers 20 to the board connector 261 of the RF board 260 respectively, if any one of the plurality of transducers 20 is damaged or needs to be replaced, only the corresponding transducer 20 can be repaired or replaced. That is, when connecting a plurality of electrode wires respectively connected to the transducer 20 to a separate power supply device all at once, there is a problem that not only the state of the transducer cannot be individually confirmed, but also individual repair and replacement are impossible. On the contrary, in the present invention, the RF board 260 is provided between the transducer 20 and a power supply device (not shown), and the second electrode wires 180 connected to the plurality of transducers 20 are respectively connected to the RF board 260 individually via board connectors, whereby individual repair and replacement of the transducer 20 become possible.

[0133] In addition, since the states of the plurality of transducers 20 can be individually monitored using a monitoring sensor (not shown) provided on the RF board 260, only the transducers 20 that need repair or replacement can be grasped more easily and quickly, and corresponding measures can be taken quickly.

[0134] Therefore, since the plurality of transducers 20 can be monitored independently and repaired or patched, maintenance and repair can be facilitated.

[0135] In addition, since the RF board 260 compatible with the probe 11 can be used, it is easy to treat various types of lesions.

[0136] On the one hand, in the above embodiment, the description was given by taking as an example that the transducer holder 100 is grounded and the RF power supply is applied only to the transducer 20. However, it is not limited thereto, and it is of course possible that the transducer holder 100 is connected to the negative electrode of the RF board 260, and the transducer 20 is connected to the positive electrode of the RF board 260 so as to have a potential difference between the transducer holder 100 and the transducer 20.

[0137] On the one hand, in the above embodiment, the description was given by taking as an example the case where the surface of the transducer holder 100 is coated with a conductive material or the entire transducer holder 100 is formed of a conductive material, and the transducer holder 100 and the transducer 20 serve as an integrated electrode. However, it is not limited thereto, and it is of course possible that the transducer holder 100 is formed of a non-conductive material, that is, an insulating material. When the transducer holder 100 is formed of an insulating material, first and second electrode lines (not shown) are connected to the upper and lower stages of the transducer 20, respectively, and the first and second electrode lines (not shown) are connected to the RF board 260.

[0138] The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those having ordinary knowledge in the technical field can understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims.
