High Intensity Focused Ultrasound (HIFU) is a non-invasive method for the treatment of cancer cells by selectively coagulating the internal organs and destroying cancer cells. However, in the United States, (Liposonix) equipped with HIFU for the first time. The process of fat destruction using high intensity focused ultrasound (HIFU) is that when the ultrasound is focused at a certain point in the adipose tissue, the tissue temperature instantaneously rises from 65 ° C to 100 ° C, thereby destroying the tissue. Unlike other dermatological equipment, such as laser and RF high frequency equipment, the HIFU equipment concentrates HIFU energy on non-invasively selected areas without causing any damage to the skin surface to induce coagulation necrosis do. These necrotic adipocytes are naturally removed by our body's repair mechanism.

Reference numeral 201 denotes a bracket for coupling the cartridge 200 and the head body 100.

Next, the operation of the ultrasonic treatment head constructed as described above according to the present invention will be described.

In general, the depth of the focus region varies depending on the treatment purpose, so that the cartridge 200 suitable for the treatment purpose is selected and mounted on the head body 100. That is, the cartridge having the ultrasonic transducer for generating the focus of the ultrasonic wave corresponding to the treatment depth is selected and mounted on the head body 100. In addition, the operation pattern and operation time of the ultrasonic transducer 226 can be selected according to the treatment site and purpose.

When the ultrasonic treatment head 10 is operated through the user interface of the ultrasonic treatment head 10, the controller drives the first rotation motor 121 or the second rotation motor 131 according to a pattern previously programmed, The ultrasonic transducer 226 is operated to generate an ultrasonic wave or a concentrated ultrasonic wave (HIFU).

When the first rotary motor 121 of the first actuator 120 is rotated, the first lead screw 122 is rotated through the coupler 112 and the first slider 123 fastened to the first lead screw 122, The first drive shaft 125 connected to the first sliders 123 and 140 moves downward as the first slider 123 moves downward along the first lead screw 122.

At this time, when the first ball joint 151b provided on the first driving shaft 125 moves downward, the stage 150 moves the second ball joint 152b of the second pivot shaft 152a and the third pivot shaft 153a And the third ball joint 153b of the second ball joint 153b.

When the second actuator 130 and the third actuator 140 are operated in the same manner as described above, the stage 150 includes the first ball joint 151b and the second ball joint 152b, the third ball joint 153b ) Pivots in various directions at a radius of 360 degrees.

When the first slider 123 of the first actuator 120 reaches the lower limit position through the position resistor 127, the controller rotates the first actuator 120 in the opposite direction to rotate the first actuator 120 So that the first slider 123 moves upward. When the second slider 133 of the second actuator 130 reaches the upper limit position in the same manner through the position resistor 137, the controller rotates the rotation direction of the second actuator 130 in the opposite direction So that the second slider 133 pushes or pulls the stage 150 while reciprocating between the upper and lower limits. When the third slider 143 of the third actuator 140 reaches the upper limit position through the position resistor 147 in the same manner, the controller reverses the rotation direction of the third actuator 140 again So that the third slider 143 pushes or pulls the stage 150 while reciprocating between the upper limit and the lower limit

The stage 150 controls the operation sequence and operating range of the first actuator 120, the second actuator 130 and the third actuator 140 so that the stage 150 freely pivots at a desired angle in various directions at a 360- It is to exercise.

Meanwhile, the pivotal movement of the stage 150 is transmitted to the planar motion converting portion of the cartridge 200, and the planar motion converting portion is configured to move the ultrasonic transducer assembly 225 mounted on the plane end by the pivoting motion, To move along the upper surface of the plane window.

At this time, in the planar motion converting unit, the length of the entire axis is changed by the compression spring 216 so that the pivot motion is converted into the planar motion, and the focus of the ultrasonic wave irradiated by the ultrasonic transducer 226 moves in a straight line on the same plane.

In other words, at the center of the ultrasound transmission window 228, the length of the planar motion converting part is shortened, the compression spring 216 is compressed a lot, and the elastic restoring force stored in the compression spring 216 is moved while moving to the periphery, The length of the conversion part is increased and the ultrasonic transducer assembly 225 is moved in a flat state while being in close contact with the flat upper surface of the ultrasonic transmission window 228. Thus, the ultrasonic wave is radiated in a flat surface in the area, The focal depth of the ultrasonic focal plane 226 is located on the same plane, that is, on the same plane.

10, the planar motion converting unit includes a connecting portion 204 connected to the lower portion of the stage 150, a lower portion coupled to the lower portion of the connecting portion 204 inside the cartridge housing 212, A second support 218 which is lifted or lowered by the pivotal movement of the stage 150, a fourth ball joint 4 provided at a lower portion of the second support 218, An ultrasonic transducer housing 224 rotatably coupled to the ball joint 4, a transverse guide 241 installed inside the cartridge housing 212, a transverse guide 241 and an ultrasonic transducer assembly 225 A connection block 242 for coupling the ultrasonic transducer housing 224 to the transverse guide 241 in the lateral direction so as to move the ultrasonic transducer housing 224 in the lateral direction along the transverse guide 241, A running guide 240 for guiding the traverse guide 241 in the longitudinal direction, It may be included.

The transverse guide 241 and the tubular guide 24 are spaced apart from the upper surface of the ultrasonic transmission window and are disposed in parallel with the plane so as to guide the ultrasonic transducer assembly 225 to linearly move on the same plane.

The ultrasonic transducer assembly 225 is moved by the transverse guide 241 and the guide 240 so that the ultrasonic transducer assembly 225 maintains a constant distance from the upper surface of the ultrasonic transmission window 228.

The transverse guide 241 and the longitudinal guide 240 serve to guide the ultrasonic transducer assembly 225 or the ultrasonic transducer housing 224 in the x and y directions. The transverse guide 241 and the longitudinal guide 240 guide the ultrasonic transducer assembly 225, A connection block for connection with the ultrasonic transducer housing 224 is coupled to the rail of the transverse guide 241. [

The connection block 242 is connected to the transverse guide 241 while the connection block 242 is connected to the transit guide 240 and the transit guide 240 is connected to the transverse guide 241 It is not so limited.

When the ultrasonic transducer housing 224 is moved in the x and y directions by the transverse guide 241 and the guide 240 as described above, the ultrasonic transducer housing 224 is moved by the fourth ball joint 4, So that stable planar movement is possible.

Next, the operation of the planar motion converting unit constructed as above will be described.

When the stage 150 is pivotally moved by the first actuator 120, the second actuator 130 and the third actuator 140, the ultrasonic transducer assembly 225 connected to the stage 150 is guided by the transverse guides 241 And in the x and y directions at the upper portion of the ultrasonic transmission window 228 along the guide member 240.

That is, since the ultrasonic transducer assembly 225 moves in a planar manner, the ultrasonic wave is radiated in a plane in the region, so that the ultrasonic focal depth of the ultrasonic transducer 226 is uniform And is positioned on a plane.

The present invention can be realized by converting the pivot movement of the stage 150 according to the operation of the first actuator 120, the second actuator 130 and the third actuator 140 into the planar motion by the planar motion converting unit, The ultrasonic transducer is moved in a plane to move the focus of the ultrasonic wave at a desired uniform depth to apply uniform energy to the treatment site to improve the treatment performance.
