Description

Transducer Module with Centrifugal Multi-Focusing System and Ultrasonic Surgery Apparatus}

The present invention relates to a transducer and an ultrasonic surgical apparatus using the same, and in particular, a plurality of ultrasonic waves irradiated in a conical shape form a concentric axis, and a transducer module configured to form a focal point of each ultrasonic wave at intervals above and below the concentric axis. And an ultrasound treatment device configured to move the transducer module in a plane and enable 3D treatment.

Recently, in medical institutions, a technique for irradiating HIFU (High Intensity Focused Ultrasound) energy to the skin and directly observing skin diseases through a monitor is being used.

HIFU (Focused Ultrasound Therapy) is a procedure to burn tissue by using high temperature of 65~100℃ generated from the focal point when high-intensity ultrasound energy is collected in one part of the skin. When focusing about 100,000 times stronger ultrasound at one point, heat is generated in the focal region.

Ultrasound itself is a technology that has the advantage of being able to treat lesions in the body without the need for general anesthesia without using a knife or needle since heat is generated only at the focal point where the ultrasound is harmless to the human body.

Due to the advantages of HIFU (Intensive Ultrasound Therapy), HIFU procedures are being performed in many medical fields, and development of HIFU equipment is progressing accordingly.

In the case of the HIFU equipment, which is a conventional ultrasonic surgical equipment, a cartridge is replaced with a handpiece in a state where each transducer is mounted on a plurality of cartridges.

As the focal length of ultrasound is set differently for the transducer of each cartridge, a suitable cartridge is mounted on the hand piece according to the location of the operator's lesion or the location of the fat distribution of the molder, and then the procedure is performed.

Such a conventional ultrasonic surgical apparatus has a problem of preparing a plurality of cartridges and selecting and replacing a suitable cartridge according to the operator.

In order to solve this problem, the ultrasonic surgical device described in Korean Patent Registration No. 10-177825 (Publication Date 2017.09.13) and Korean Patent Publication No. 10-2017-0063460 (Publication Date 2017.06.08) are multifocal. It has a function.

As described above, although the conventional multifocal ultrasound surgical device implements multifocal, there is a problem in that the size of the cartridge increases as the arrangement of transducers is arranged in a vertical or transverse direction, and thus the accuracy of the procedure is deteriorated. have.

Also, as described above, the temperature near the focal point including the focal point is a high temperature of 65 to 100°C.

As shown in Figures 1 and 2, in the case of a conventional ultrasonic surgical device in which the transducers 1 and 2 are arranged in the longitudinal or transverse direction, the ultrasonic waves are irradiated in the form of a cone in each transducer 1 and 2 Accordingly, the cross-sectional area of the ultrasound region before reaching the focus is formed for each transducer 1 and 2, and thus the area where high temperature outside the focus occurs is widened as a whole.

In this case, there is a problem in that high-temperature heat is generated in tissues other than the tissues required for the procedure, and tissue cells other than normal cells or fats are burned by high-temperature heat or tissues are necrotic.

This is due to a structural problem as the array of transducers is not overlapped and widely distributed as described above.

As shown in FIG. 3, the ultrasound treatment apparatus 100 includes a controller 101 and a handpiece 110 mounted at an end of the cable 103 extending from the controller 101.

The controller 101 is provided with a touch-type control window 101W, and control of operation and movement of the transducer module 160 mounted in the handpiece 110 is performed through the control window 101W.

In addition, the handpiece 110 includes a main body 111 and a cartridge 140 detachably mounted on the bottom surface of the main body 111.

The handpiece 110 is connected to a power cable and a signal cable extended from the controller 101, and these cables 103 are introduced into the body 111 of the handpiece 110. Here, the signal cable is a cable used for the operation of the motors 114A and 114B and the control of the transducer module 160.

Meanwhile, a switch (112 of FIG. 5) is mounted on the side of the main body 111 to turn on/off the power supplied to the transducer module 160. Three motors 114A, 114B are disposed at an isometric angle of 120 degrees inside the main body 111, the shafts of the motors 114A, 114B extend downward, and the screws 115 are mounted on the shafts, respectively.

In the drawing, FIG. 4 is a rotational sectional view showing an angle of 120° between two motors.

4 to 6, the ends of each of the three screws 115 are rotatably coupled to a fixed frame 116 fixed inside the main body 111, so that each screw 115 is connected to a motor According to the operation of (114A, 114B), it rotates at a fixed position, and the rotation of the three motors (114A, 114B) is controlled in the control window (101W).

Meanwhile, the moving plate 120 is screwed to each screw 115. Therefore, according to the operation of each motor (114A, 114B), each screw 115 rotates, and each moving plate 120 screwed to the screw 115 moves up and down according to the rotation direction of the screw 115. .

To allow the moving plate 120 to move smoothly in the vertical direction, a through hole through which the guide bar 121 penetrates is formed in the moving plate 120, and a tilting bar 127 is fixed to the bottom surface of the moving plate 120. The guide bar 121 passing through the through-hole of the moving plate 120 is fixed to the fixed frame 116 and positioned.

In addition, the moving plate 120 is connected to the position sensor 124, the position sensor 124 is located in the center of the three motors (114A, 114B) is disposed at an angle of 120 degrees, three moving plates (120) The sensing bar 125 extended from) is connected to the position sensor 124. Accordingly, when each of the motors 114A and 114B is operated, the moving plate 120 moves up and down, and the position detecting sensor 124 recognizes the sensing bar 125 extended from the moving plate 120 to move the moving plate 120. ). That is, the height of the moving plate 120 is detected and recognized by the position sensor 124.

The tilting bar 127 fixed to the bottom surface of the moving plate 120 extends downward and the lower end of the tilting bar 127 is hinged to the tilting plate 130 located below the fixing frame 116. Therefore, three hinge coupling portions 131 are formed on the upper surface of the tilting plate 130 at an isometric angle of 120 degrees, and the tilting bar 127 is downward when the moving plate 120 is moved by the respective motors 114A and 114B. When moving to, one portion of the tilting plate 130 to which the tilting bar 127 which moves downward moves downward, so that the tilting plate 130 is inclined. Conversely, when the moving plate 120 moves upward by each of the motors 114A and 114B, the tilting bar 127 also moves upward, and accordingly the tilting plate 130 to which the tilting bar 127 moving upward moves. Tilting plate 130 is inclined while one portion of the moving upward.

As such, as the three motors 114A and 114B operate, the tilting bar 127 moves up and down, and the tilt of the tilting plate 130 changes. The tilt change of the tilting plate 130 is detected by the position sensor 124 that detects the vertical movement of the moving plate 120 to detect and recognize the tilt of the tilting plate 130.

Meanwhile, the ultrasonic surgical apparatus according to the present invention precisely controls the position of the transducer module 160 by transmitting a change in the tilt of the tilting plate 130 to the transducer module 160 mounted inside the cartridge 140.

As shown in FIG. 8, the cartridge 140 has a transducer module 160 disposed therein, and the interior of the cartridge 140 is filled with cooling water to prevent overheating of the transducer module 160.

On the other hand, in order to move the transducer module 160 by the tilt of the tilting plate 130, the cartridge 140, when mounted on the bottom of the body 111 of the handpiece 110, the flat plate in contact with the tilting plate 130 (141), fastened to the center of the bottom surface of the flat plate 141 and extended downward to penetrate the upper surface of the tilting shaft 143 and the tilting shaft 143 and the cartridge 140 extending into the interior of the cartridge 140 There is a first ball joint 151 for preventing leakage of cooling water, and a second ball joint 152 mounted on the upper surface of the transducer module 160 and positioned at the lower end of the tilting shaft 143.

In addition, the Z-axis bar 163 passes through the upper end of the transducer module 160, and both ends of the Z-axis bar 163 are mounted on the X-axis rail 165 mounted inside the cartridge 140. Therefore, the movement range of the transducer module 160 is limited to the plane by the Z-axis bar 163 and the X-axis rail 165. That is, even if the transducer module 160 moves as the tilting plate 130 is inclined, only the plane moves along the Z-axis bar 163 and the X-axis rail 165.

The cartridge 140 configured as described above is formed with unlock buttons 145 on both sides thereof, and when the unlock button 145 is pressed, the cartridge 140 is released from the main body 111, and the cartridge 140 is mounted on the main body 111. Push up from the bottom of the lock release button 145 is protruded and locked.

As described above, when the cartridge 140 is locked to the bottom of the main body 111, the flat plate 141 comes into contact with the bottom surface of the tilting plate 130.

Hereinafter, the coupling relationship and the moving relationship of the transducer module on the plate of the cartridge will be described in detail.

7, the ball 151B of the first ball joint 151 is formed in the middle of the length of the tilting shaft 143, and the ball 151B of the first ball joint 151 is the cartridge 140 Located over the hole formed in the upper surface (140H) of. And the cover 153 is fixed to the upper surface 140H of the cartridge 140 in a state surrounding the ball 151B of the first ball joint 151, wherein the cover 153 and the upper surface 140H of the cartridge 140 ) Between the sealing member 155 and the sealing member 155 is positioned in close contact with the ball 151B of the first ball joint 151. Therefore, the cooling water accommodated in the cartridge 140 is not leaked through the hole formed in the upper surface of the cartridge 140.

Meanwhile, as the flat plate 141 in contact with the tilting plate 130 is inclined with the inclination of the tilting plate 130, the tilting shaft 143 is tilted around the ball 151B of the first ball joint 151.

As described above, as the tilting shaft 143 is inclined, the transducer module 160 to which the lower end of the tilting shaft 143 is connected moves.

A second ball joint 152 is formed on the upper surface of the transducer module 160, and the lower end of the tilting shaft 143 is inserted into the upper end of the ball 152B of the second ball joint 152. This protrudes upward.

Here, while the lower end of the tilting shaft 143 is inserted into the insertion tube 157, the tilting axis 143 is movable in the longitudinal direction of the insertion tube 157. That is, the length of the tilting shaft 143 and the insertion tube 157 is expandable. The reason for such a flexible construction will be described below.

As the tilting axis 143 is inclined, the second ball joint 152 coupled transducer module 160 moves along the direction in which the lower end of the tilting shaft 143 moves, as described above. As the 160 is limited to move in a plane by the Z-axis bar 163 and the X-axis rail 165, the transducer module 160 is movable only on the planes that are the X-axis and the Z-axis.

As described above, the transducer module 160 moves in a plane, while the tilting shaft 143 rotates or rotates relative to the first ball joint 151, so that the rotational movement of the tilting shaft 143 is the transducer. Compensation due to the conversion to the plane movement of the module 160 can be compensated as the lengths of the tilting shaft 143 and the insertion tube 157 described above are stretched and contracted.

That is, when the inclination of the tilting axis 143 decreases, as the distance from the ball 151B of the first ball joint 151 to the transducer module 160 increases, the tilting axis 143 in the insertion tube 157 As the length of the withdrawal increases, on the contrary, when the inclination of the tilting shaft 143 increases, the end of the tilting shaft 143 is drawn into the insertion tube 157, and the distance is shortened, so that the rotational movement of the tilting shaft 143 is a transducer module. It becomes possible to switch to the plane motion of 160.

Hereinafter, in the ultrasonic surgical apparatus configured as described above, the configuration of the transducer module 160 according to the present invention will be described in detail.

7 to 8, the transducer module 160 is a transducer holder 161 is mounted with three transducers (167A, 167B, 167C), and the upper center of the transducer holder 161 It includes a second ball joint 152 mounted. And a pair of Z-axis bars 163 penetrate the transducer holder 161.

As shown in FIG. 9, the transducer holder 161 has a circular first transducer 167A, a second transducer 167B surrounding the circumference of the first transducer 167A, and a second transducer ( It includes a third transducer (167C) surrounding the circumference of 167B).

As the second transducer 167B and the third transducer 167C are positioned in an annular shape with the first transducer 167A configured as described above, the first transducer 167A to the third transducer 167C The center points are the same, and the focal points are sequentially arranged downwardly on the center line.

As described above, as the three focal points 168A, 168B, and 168C are aligned and arranged downward on the centerline, features according to each focal point 168A, 168B, and 168C can be implemented, and as the ultrasonic regions overlap, the transducer holder 161 ) Can be reduced, and accordingly, the overall size of the handpiece 110 can also be reduced.

And in the ultrasound region of the third transducer 167C having the largest diameter, the ultrasound regions of the first transducer 167A and the second transducer 167B are located inside the ultrasound region of the third transducer 167C. As it is done, it is possible to prevent heat from being applied to tissues other than the tissue to be treated by reducing the occurrence of high temperature in the area outside the focus of the third transducer 167C.

Meanwhile, a part of the cable 103 extended to the main body 111 is connected to the bottom surface of the main body 111, that is, the connection connector 117M formed on the side of the tilting plate 130, and extends from the transducer module 160. The cable is connected to the connecting connector 147F formed on the upper surface of the cartridge 140, that is, on the side of the flat plate 141. Therefore, when the cartridge 140 is mated to the main body 111 and locked, the connection connector 117M of the main body 111 and the connection connector 147F of the cartridge 140 are connected to the transducers 167A, 167B, and 167C. It becomes possible to supply the power required for operation.

In addition, as the transducer module 160 moves in a plane with three focal points formed in this way, there is an advantage in that a three-dimensional operation is possible in three dimensions.

On the other hand, in the ultrasonic treatment apparatus 100 described above, three motors 114A and 114B are described as being installed inside the main body 111 to control the tilt of the tilting plate 130, but this means that the minimum number of motors is used. As shown, three or more motors may be mounted to control the tilt of the tilting plate 130. In this case, the configuration connected from the motor to the tilting plate also consists of three or more.
