Description
Technical Field
The present invention relates to an ultrasonic apparatus, and more particularly, to an ultrasonic apparatus using high-intensity focused ultrasonic waves and employing a method of reciprocating a transducer.
Background
In recent years, a variety of procedures for cosmetic skin and obesity treatment have been developed and there is increasing interest in procedures performed by non-invasive methods.
Ultrasound devices have been widely used for non-invasive surgery, and ultrasound devices that utilize High Intensity Focused Ultrasound (HIFU) have recently become popular. For example, ultrasound devices are being developed to non-invasively perform cosmetic procedures (e.g., facial lifting or skin tightening) by directing high intensity focused ultrasound into skin tissue, or to non-invasively treat obesity by directing high intensity focused ultrasound into subcutaneous fat layers to non-invasively burn, melt and break down fat tissue.
A high intensity focused ultrasound device for skin cosmetic surgery includes an image monitor, an ultrasound control unit, and a handpiece coupled to a barrel containing a transducer that generates ultrasound waves.
Such an ultrasonic device is a structure in which a transducer that generates ultrasonic waves performs reciprocating linear motion by rotating a screw unit having threads in one of a forward direction and a reverse direction. In this case, a deceleration section before the direction change and an acceleration section after the direction change are required to control the rotation direction of the driving motor, thereby causing an unnecessary traveling section and increasing the time required for the reciprocation.
Disclosure of Invention
The present invention aims to provide an ultrasound device that reduces the time required for reciprocation and has simple control of the drive motor.
An ultrasound apparatus employing a method of reciprocation of a transducer according to the present invention, the ultrasound apparatus comprising: a barrel portion including a transducer configured to generate ultrasonic waves; and a mobile device configured to move the transducer, wherein the mobile device comprises: a moving body; a moving block on the moving body and connected to the transducer and configured to move together with the transducer; a moving connection member connected to the moving block; and a screw unit engaged with the moving connection member to allow the moving block to reciprocate, wherein the screw unit has a bidirectional thread.
The bi-directional thread may include: a first thread formed on a surface of the screw unit in a first oblique direction; a second screw thread formed on a surface of the screw unit in a second inclined direction crossing the first inclined direction; and a connecting thread configured to connect the first thread to the second thread.
The connecting thread may include: a first connection thread formed on one side of the screw unit; and a second connecting thread formed on the other side of the screw unit.
The movable connecting member may be inserted into and travel along the bi-directional thread.
The mobile connection member may include: an insertion portion inserted into the bidirectional screw thread; and a connection portion connected to the insertion portion and engaged with the moving block.
The traveling direction of the moving block may be changed from a first direction to a second direction opposite to the first direction after the moving connection member passes the first connection screw, and the traveling direction of the moving block may be changed from the second direction to the first direction after the moving connection member passes the second connection screw.
The mobile device may further include: a drive motor configured to provide drive power to the screw unit; and a pair of guide members connected to the moving block and configured to guide the moving block to reciprocate.
The moving device is mounted on the moving body, and may further include a motion sensor configured to detect a motion of the moving block.
The barrel portion may further include a pressure sensor mounted at a lower end of the barrel portion and configured to measure externally applied pressure.
[ advantageous effects ]
An ultrasonic device according to an embodiment of the present invention can allow the moving block 222 to reciprocate in the first direction and the second direction by forming a bidirectional screw on the screw unit without changing the rotation direction of the screw unit. Accordingly, since a deceleration section before the direction change of the moving block and an acceleration section after the direction change of the moving block are not required, an unnecessary traveling section can be minimized, thereby minimizing the time required for the reciprocation.
Further, since the driving motor can rotate the screw unit in one direction to allow the moving block to reciprocate, a separate control device for changing the rotation direction of the driving motor is not required.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily implement the embodiments. The present invention may be implemented in a variety of different ways and is not limited to the embodiments described herein.

As shown in fig. 1 to 3, an ultrasound apparatus according to an embodiment of the present invention includes a cartridge 100 and a handpiece 200, the cartridge 100 including a transducer 120 for irradiating a person to be treated with HIFU, the handpiece 200 being configured to adjust a treatment range for irradiating the person to be treated with HIFU.
The cartridge 100 may include a cartridge body 110 and a transducer 120 that generates ultrasonic waves.
The transducer 120 may be mounted inside the cartridge body 110. Transducer 120 may illuminate and treat a person to be treated with HIFU.
The handpiece 200 may include a handpiece body 210 and a moving device 220, the moving device 220 being mounted within the handpiece body 210 and moving the transducer 120.
The handpiece body 210 has a generally rectangular parallelepiped shape, but is not necessarily limited thereto, and various other shapes are possible.
The moving device 220 may include a moving body 221, a moving block 222, a moving connection member 223 (see fig. 3), a screw unit 224, a driving motor 225, and a pair of guide members 226.
The moving body 221 may support the moving block 222, the moving connection member 223, and the screw unit 224.
The moving block 222 is located on the moving body 221 and connected to the transducer 120 such that the moving block 222 can move together with the transducer 120. The first magnetic member 11 may be mounted on an upper portion of the moving block 222.
The moving connection member 223 may connect the moving block 222 and the screw unit 224.
The screw unit 224 is engaged with the moving connection member 223 such that the moving block 222 can reciprocate by rotation of the screw unit 224. The screw unit 224 may have a bi-directional thread 40.
Fig. 4 is a perspective view showing a state in which a movable connection member according to an embodiment of the present invention is coupled to a screw unit 224 of an ultrasonic device, and fig. 5 is a view explaining a state in which the movable connection member according to an embodiment of the present invention moves according to rotation of the screw unit of the ultrasonic device.
As shown in fig. 4 and 5, the bidirectional screw 40 may include a first screw P1 formed on the surface of the screw unit 224 along a first inclined direction Y1, and a second screw P2 formed on the surface of the screw unit 224 along a second inclined direction Y2 crossing the first inclined direction Y1; and a connecting thread P3 connecting the first thread P1 and the second thread P2.
Further, the connection screw P3 may include a first connection screw P31 formed on one side of the screw unit 224 and a second connection screw P32 formed on the other side of the screw unit 224. In this case, the first coupling screw P31 may include a first sub-coupling screw P311, a second sub-coupling screw P312 intersecting the first sub-coupling screw P311, and a first turning screw P313 connecting the first sub-coupling screw P311 and the second sub-coupling screw P312 and turning the direction.
Similarly, the second coupling screw thread P32 may include a third sub-coupling screw thread P321, a fourth sub-coupling screw thread P322 intersecting the third sub-coupling screw thread P321, and a second turning screw thread P323 connecting the third sub-coupling screw thread P321 and the fourth sub-coupling screw thread P322 and turning the direction.
The movable connecting member 223 is inserted into the bi-directional screw thread 40 and may travel along the bi-directional screw thread 40. The moving connection member 223 may include an insertion portion 231 inserted into the bi-directional screw 40, and a connection portion 232 connected to the insertion portion 231 and engaged with the block groove 222a of the moving block 222. When the moving connection member 223 moves, the moving block 222 engaged with the moving connection member 223 also moves together, and when the moving block 222 moves, the transducer 120 magnetically coupled to the moving block 222 also moves together. In this case, the first magnetic member 11 mounted on the upper portion of the moving block 222 is magnetically coupled with the second magnetic member 12 mounted on the lower portion of the transducer 120.
As shown in fig. 5, when the screw unit 224 is rotated in one direction R by the driving motor 225, the moving connection member 223 inserted into the first screw P1 travels in the first direction X1 (S1).
Subsequently, when the screw unit 224 rotates in one direction R, the moving connection member 223 is positioned on the first sub-connection screw P311 formed on one side of the screw unit 224. The movable connection member 223 inserted into the first sub-connection screw P311 travels in the first direction X1 according to the rotation of the screw unit 224 (S2).
Then, when the screw unit 224 rotates in one direction, the movable connection member 223 passes through the first turning screw P313 connected to the first sub-connection screw P311, and is positioned on the second sub-connection screw P312. The movable connection member 223 positioned on the second sub-connection screw P312 travels in a second direction X2 opposite to the first direction X1 according to the rotation of the screw unit 224 (S3). As described above, the moving connecting member 223 passes through the first turning screw P313, and the traveling direction of the moving connecting member 223 may be changed from the first direction X1 to the second direction X2.
That is, after the moving connection member 223 is then advanced through the first connection screw P31, i.e., the first sub-connection screw P311, the first turning screw P313, and the second sub-connection screw P312, the advancing direction of the moving block 222 may be changed from the first direction X1 to the second direction X2.
Subsequently, when the screw unit 224 rotates in one direction R, the moving connection member 223 inserted into the second thread P2 connected to the second sub-connection thread P312 travels in the second direction X2 (S4).
Similarly, when the screw unit 224 rotates in one direction R, after the moving connection member 223 then travels through the second connection screw P32 formed on the other side of the screw unit 224, that is, the third sub-connection screw P321, the second turning screw P323, and the fourth sub-connection screw P322, the traveling direction of the moving block 222 may be changed from the second direction X2 back to the first direction X1.
As described above, by forming the bidirectional screw 40 on the screw unit 224, the ultrasonic device according to the embodiment of the present invention can allow the moving block 222 to reciprocate in the first direction X1 and the second direction X2 without changing the rotation direction of the screw unit 224. Accordingly, since a deceleration section before the direction change of the moving block 222 and an acceleration section after the direction change of the moving block 222 are not required, an unnecessary traveling section can be minimized, thereby minimizing the time required for the reciprocation.
As shown in fig. 2, the driving motor 225 may provide a driving force to the screw unit 224 to rotate the screw unit 224 in one direction R, thereby allowing the moving block 222 to reciprocate. As described above, since the driving motor 225 can rotate the screw unit 224 in one direction to allow the moving block 222 to reciprocate, a separate control device for changing the rotation direction of the driving motor 225 is not required.
The pair of guide members 226 penetrate the moving block 222, and may guide the moving block 222 to reciprocate along the first direction X1 and the second direction X2. The pair of guide members 226 may include a first guide member 261 and a second guide member 262 located at both sides of the screw unit 224, respectively.
The moving device 220 may further include a position control unit 60, and the position control unit 60 controls the position of the moving block 222 reciprocating in the first direction X1 and the second direction X2. The position control unit 60 may include a position determining part 61 mounted on the moving body 221 corresponding to the screw unit 224, and an encoder 62 mounted on the driving motor 225. The position determining section 61 may include a variable resistor that determines the position of the moving block 222 based on the resistance difference, or a photosensor that determines the position of the moving block 222 based on the light intensity difference.
Meanwhile, the cartridge part 100 of the ultrasonic device according to the embodiment of the present invention may further include a pressure sensor 400.
The pressure sensor 400 may be installed at the lower end of the cartridge 100, i.e., the lower end of the cartridge body 110, to measure externally applied pressure.
The related art ultrasonic device has a treatment depth of 1mm to 5mm depending on the position of the transducer within the barrel. However, since the depth of treatment may be deeper or shallower (depending on the pressure with which the operator presses the barrel against the treatment area with the handpiece), the depth of treatment becomes inconsistent, as the effectiveness of the treatment is determined by the skill level of the operator.
However, by installing the pressure sensor 400 at the lower end of the barrel part 100, the ultrasonic device according to the embodiment of the present invention can measure the pressure of the handpiece applied to the treatment area, and when the correct pressure is applied, the operator can recognize the pressure of the handpiece using light or sound. Thus, the same therapeutic effect can be achieved regardless of the skill level of the operator.
The mobile device 220 may also include a motion sensor 500. The motion sensor 500 is mounted on the moving body 221, and can detect the motion of the moving block 222.
In the related art ultrasound apparatus, an operator moves a handpiece to navigate a treatment area to apply ultrasonic waves to a plurality of treatment areas, but cannot accurately verify movement to the treatment area, so when a barrel is not accurately moved to the treatment area, heat may be applied again to the same area, resulting in skin necrosis in the treatment area.
However, by mounting the motion sensor 500 on the moving body 221 of the hand piece 200, the ultrasonic device according to the embodiment of the present invention can perform ultrasonic irradiation again when the movement to the treatment area is confirmed after detecting the movement of the moving block 222. That is, after the motion sensor 500 confirms the treatment position of the moving block 222, light or sound may be used to help the operator confirm the exact position of the treatment area. Therefore, the operator does not need to recognize the position of the ultrasonic irradiation each time, and even when the ultrasonic device is operated in the continuous mode, heat is not applied to the same treatment area, which can prevent skin necrosis in the treatment area.
The motion sensor 500 may include a gyro sensor, an accelerometer, a geomagnetic sensor, and the like.
While the present invention has been described with reference to the above-described exemplary embodiments, those skilled in the art will readily understand that the present invention is not limited to the disclosed exemplary embodiments, but various corrections and modifications may be made without departing from the scope of the appended claims.
