Technical Field

The invention relates to a medical shock wave generating device, in particular to a permanent magnet shock wave generating device.

Background

The shock wave is a mechanical wave generated by sudden release in a certain limited space in gas or liquid, is an energy transfer process, is widely applied to clinical medicine at present, and is mainly used for treating urinary calculus, hepatobiliary calculus, nonunion of fracture, femoral head necrosis, aseptic soft tissue injury, pain caused by the aseptic soft tissue injury, erectile dysfunction, cardiovascular function and other diseases. The existing electromagnetic shock wave source consists of a cup body, an electromagnetic disc, a lens and a water sac. The electromagnetic disc is fixedly arranged at the bottom of the cup body and is used as a device for generating shock waves; a lens is arranged in the middle of the cup body and is used as a device for changing the propagation direction of the shock wave; the cup body is provided with a water sac, and water is filled in the cup body to be used as a medium for shock wave conduction. The electromagnetic disc as the core part of the shock wave technology consists of a ceramic disc, a coil, an insulating layer, a metal vibrating diaphragm and a rubber film. The coil adopts the winding method of disc type, and the coil is fixed on the porcelain plate, is equipped with the insulating layer on the coil, and the insulating layer top is equipped with the metal vibrating diaphragm, and the metal vibrating diaphragm top is equipped with the rubber membrane, and the rubber membrane compresses tightly coil, insulating layer and metal vibrating diaphragm. After pulse current is input to the coil, the coil generates a magnetic field. According to Lenz's law, the metal diaphragm is subjected to outward thrust in a direction perpendicular to the central axis of the coil when the magnetic field of the coil is increased by an induced magnetic field produced by the diaphragm; when the magnetic field of the coil is reduced, the metal vibrating diaphragm is subjected to inward tensile force in a direction perpendicular to the central axis of the coil. Every time the pulse current passes through the coil, the vibrating diaphragm generates a shock wave due to the vertical vibration.

However, the shock wave vibration energy in the prior art has high requirements on current and voltage, so that the service life and the reliability of the shock wave vibration energy are correspondingly limited; secondly, because the pulse current of the electromagnetic shock wave source in the prior art is large, and the coil is arranged close to the vibrating diaphragm, the heat generated by heating can be directly transferred into a propagation medium (such as water) and then transferred to a human body, and therefore, a water circulation system is required to be arranged in the water bag to realize heat dissipation; thirdly, the electromagnetic shock wave source in the prior art has higher requirements on a matched power supply.

Disclosure of Invention

The technical problem to be solved by the invention is to provide a permanent magnet type shock wave generating device which can generate larger energy, further effectively prolong the service life of a product and improve the reliability of the product, and further can further reduce the requirement on a matched power supply.

In view of the above, the present invention provides a permanent magnet type shock wave generating apparatus comprising: the water-saving cup comprises a cup body, a water bag, a vibrating diaphragm, a permanent magnet vibrating body, a base and a coil, wherein the water bag is arranged on the cup body, the vibrating diaphragm is arranged below the water bag, and a cavity between the water bag and the vibrating diaphragm is filled with a shock wave conduction medium; the permanent magnet vibration body is fixedly arranged below the vibration diaphragm, and the base is arranged in the cup body; the coil is arranged on the base and wound on the periphery of the permanent magnet vibrating body; when the coil is electrified, a magnetic field with the same polarity direction as the permanent magnet vibrating body is generated.

The invention is further improved in that a coil base is arranged on the base, and the coil is wound on the coil base.

The coil base is a hollow cylinder base, and the height of the hollow cylinder base is smaller than the distance between the base and the diaphragm.

The invention is further improved in that the coil base is a circular ring cylinder base, and the permanent magnet vibrator is a cylindrical permanent magnet.

The invention is further improved in that the diameter of the permanent magnet vibrator is smaller than the inner diameter of the circular ring cylinder base, and the height of the permanent magnet vibrator is smaller than the distance between the diaphragm and the base.

A further development of the invention is that the lower plane of the permanent magnet oscillating body is equal to or higher than the middle point of the height of the coil.

A further improvement of the invention is that the upper surface of the diaphragm is convexly curved for generating a diverging impact beam.

A further development of the invention is that the upper surface of the diaphragm is planar for generating a shock beam parallel to the central axis of the diaphragm.

A further improvement of the present invention is that the upper surface of the diaphragm is a concave curved surface for generating a converging impact beam.

The invention is further improved in that the upper surface of the diaphragm is a spherical crown curved surface for generating shock waves focused at the center of a sphere.

The invention is further improved in that the upper surface of the diaphragm is a cylindrical section curved surface for generating line-focused shock waves on the central axis of the cylinder.

Compared with the prior art, the invention has the beneficial effects that: when the coil is electrified, the coil generates a magnetic field with the same polarity direction as the permanent magnet vibration body, and the permanent magnet vibration body is subjected to thrust in the direction of the axial line of the coil upwards under the action of the magnetic field of the coil; the permanent magnet vibrating body is fixedly arranged below the vibrating diaphragm, so that the vibrating diaphragm can generate pulse vibration under the driving of the permanent magnet vibrating body to form shock waves; because the invention adopts the permanent magnet vibration body, the coil is wound and arranged at the periphery of the permanent magnet vibration body, the magnetic flux density is high, the interaction between the induced magnetic field of the coil and the permanent magnet is strong, the kinetic energy conversion efficiency is high, and the effect of generating shock waves is obvious, therefore, the pulse current required for obtaining the same kinetic energy is smaller, further, the service life of the product is effectively prolonged, the reliability and the safety of the product are improved, and the configuration requirement on an externally matched power supply and a system is smaller.

On the basis, as the coil is arranged on the base, more preferably, the coil is wound on the coil base, the coil is not in direct contact with the permanent magnet vibration body and the vibration diaphragm, heat generated by the coil is transferred to the base, and the vibration diaphragm does not generate heat, so that the inside of the water bag is not required to be cooled by a water circulation system.

In addition, the pulse electric energy acting on the coil can be further set to be adjustable, so that the size of the shock wave energy can be adjusted, and the proper shock wave energy can be selected according to different patients and indications; because the physical shape of the diaphragm can be changed, the shock wave beams with divergence, straight line, convergence, point focusing and line focusing can be respectively generated by adopting a convex surface, a plane, a concave surface, a spherical crown surface and a cylinder section, so as to achieve different treatment application purposes.

Detailed Description

Preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, the present example provides a permanent magnet type shock wave generating apparatus including: the water cup comprises a cup body 1, a water bag 2, a vibrating diaphragm 3, a permanent magnet vibrating body 4, a base 5 and a coil 6, wherein the water bag 2 is arranged on the cup body 1, the vibrating diaphragm 3 is arranged below the water bag 2, and a cavity between the water bag 2 and the vibrating diaphragm 3 is filled with shock wave conduction media; the permanent magnet vibrating body 4 is fixedly arranged below the vibrating diaphragm 3, and the base 5 is arranged in the cup body 1; the coil 6 is arranged on the base 5 and wound on the periphery of the permanent magnet vibration body 4; when the coil 6 is electrified, a magnetic field with the same polarity direction as the permanent magnet vibrator 4 is generated.

It should be noted that, in this embodiment, the coil 6 is disposed on the base 5 and wound around the periphery of the permanent magnet vibrating body 4, and the coil 6 is not in direct contact with the permanent magnet vibrating body 4 and the diaphragm 3, so that heat generated by the coil 6 is transferred to the base 5, the diaphragm 3 does not generate heat, and the water circulating system is no longer needed to dissipate heat inside the water bag 2.

The water bag 2 is used for containing a conducting medium 8, and the conducting medium 8 can be water or other liquid; the permanent magnet vibrator 4 is a vibrator made of a permanent magnet material. When the coil 6 is electrified, the coil 6 generates a magnetic field with the same polarity direction as that of the permanent magnet vibrator 4, and due to the principle that like poles repel each other, the permanent magnet vibrator 4 is subjected to thrust in the direction which is the axial upward direction of the coil 6 under the action of the magnetic field of the coil 6; the permanent magnet vibration body 4 is fixedly arranged below the vibration diaphragm 3, so that the vibration diaphragm 3 can generate pulse vibration under the driving of the permanent magnet vibration body 4 to form shock waves.

That is, in practical application, only pulse current needs to be input into the coil 6, and the force applied to the permanent magnet vibrator 4 is gradually increased at the rising edge of the current pulse; when the current pulse reaches the peak value, the magnetic field of the coil 6 is strongest, and the force applied by the permanent magnet vibration body 4 is the largest; when the current pulse is decreased, the magnetic field of the coil 6 is gradually weakened, the stress of the permanent magnet vibration body 4 is gradually reduced, and the vibration energy of the vibration membrane 3 is also gradually reduced. The permanent magnet vibration body 4 is fixedly connected with the vibration diaphragm 3, and the vibration diaphragm 3 is driven by the permanent magnet vibration body 4 to generate pulse vibration to form shock waves with energy far exceeding that of the prior art.

It should be noted that, since the permanent magnet is adopted in the permanent magnet vibrating body 4, and the coil 6 is wound around the periphery of the permanent magnet vibrating body 4, the magnetic flux density is large, the interaction between the induced magnetic field of the coil 5 and the permanent magnet vibrating body 4 is strong, the conversion efficiency between the electromagnetic energy and the kinetic energy is higher, the effect of generating shock waves is remarkable, the pulse current required for obtaining the same kinetic energy is smaller, further, the service life of the product is effectively prolonged, the reliability and the safety of the product are improved, and the configuration requirement for an externally matched power supply and a system is smaller.

It should also be noted that, since the present embodiment uses the vibrating diaphragm 3, the permanent magnet vibrating body 4 and the coil 6 which are mutually matched, the heat generating source is the coil 6, the pulse current is small, so that the generated heat can be greatly reduced, on the basis, the coil 6 is arranged on the base 5 and is not in contact with the permanent magnet vibration body 4 and the vibration membrane 3, the heat is transferred to the base 5 and is not directly transferred to a shock wave transfer medium, a circulating system of the shock wave transfer medium (water) is not needed to realize heat dissipation, compared with the prior art that the conduction and heat dissipation effects are realized by water in the water bag and a water circulation system thereof, the conduction medium 8 only needs to be used for realizing the conduction effect, and the whole product has much simpler structure and lower cost than the prior art and is also beneficial to installation and maintenance; on the basis, as the water circulation is not needed to realize heat dissipation, the service life of the product can be further prolonged, and the reliability of the product is improved.

In this embodiment, the base 5 is provided with a coil base 7, and the coil 6 is wound on the coil base 7, so that the coil 6 can be conveniently arranged and mounted. Preferably, the coil base 7 is a hollow cylindrical base having a height smaller than the distance between the base 5 and the diaphragm 3, so that the coil base 7 is directly inserted between the cup body 1 and the permanent magnet vibration body 4. The coil 6 is wound around the periphery of the permanent magnet vibrator 4 through the coil base 7 and is isolated from the permanent magnet vibrator 4, so that heat of the coil 6 is transferred to the base 5.

In this embodiment, the coil base 7 is a circular ring cylinder base, and the permanent magnet vibrator 4 is a cylindrical permanent magnet; the diameter of the permanent magnet vibrator 4 is smaller than the inner diameter of the circular cylindrical base, and the height of the permanent magnet vibrator 4 is smaller than the distance between the diaphragm 3 and the base 5, so that the permanent magnet vibrator 4 is conveniently sleeved in the coil base 7, and the coil 6 can be directly wound on the periphery of the permanent magnet vibrator 4 through the coil base 7. In practical applications, the permanent magnet vibrating body 4 is not limited to a cylinder shape, but may be in other shapes; correspondingly, the shape of the coil base 7 only needs to be matched with the permanent magnet vibrating body 4 and can be sleeved outside the permanent magnet vibrating body 4 and inside the cup body 1. The cylinder type is preferable in this example because such a structure is the simplest and also facilitates the movement in the up-down direction.

The reason why the lower plane of the permanent magnet vibrator 4 is equal to or higher than the middle point of the height of the coil 6 in this embodiment, that is, the permanent magnet vibrator 4 exceeds the middle section of the coil 6, is that if the permanent magnet vibrator 4 exceeds the middle section of the coil 6, a part lower than the middle point of the height of the coil 6 exerts an opposite force on the permanent magnet vibrator 4, and further weakens the upward force of the permanent magnet vibrator 4.

It should be noted that the upper surface of the diaphragm 3 in this embodiment is not limited to the plane shown in fig. 1 and 2, and different therapeutic purposes can be achieved by replacing the diaphragm 3 with a different upper surface; preferably, as shown in fig. 3, the upper surface of the diaphragm 3 in this embodiment may be a convex curved surface, and the diaphragm 3 whose upper surface is the convex curved surface can be used to generate divergent shock beams, so as to be effectively used to remove wrinkles and treat soft tissues, and thus, a foundation is provided for a shock wave generating device that needs to diverge the shock beams. As shown in fig. 1 and 2, the upper surface of the diaphragm 3 in this embodiment may be a plane for generating a shock wave beam parallel to the central axis of the diaphragm 3, so as to provide a foundation for a shock wave generating device requiring a parallel shock wave beam, such as for treating erectile dysfunction. As shown in fig. 4, the upper surface of the diaphragm 3 in this embodiment may be a concave curved surface, and the diaphragm 3 with the concave curved surface on the upper surface can be used to generate a convergent shock wave beam, so as to provide a basis for a shock wave generating device that needs to converge the shock wave beam, that is, provide a shock wave between parallel and focused. As shown in fig. 5, the upper surface of the diaphragm 3 in this embodiment is a spherical crown curved surface, and the diaphragm 3 with the upper surface being the spherical crown curved surface (i.e. spherical curved surface) can be used to generate shock waves focused at the spherical center, so as to treat urinary calculus, peyronie's disease, femoral head necrosis, nonunion, coronary heart disease, and the like. As shown in fig. 6, the upper surface of the diaphragm 3 in this embodiment is a curved surface with a cylindrical section, that is, the upper surface of the diaphragm 3 is similar to an arc-shaped section cut out from a cylinder, and at the center of the cylinder of the arc-shaped section cut out from the cylinder, a line focus on the central axis of the cylinder is generated, so that the line focus shock wave can be generated, and the line focus shock wave is very suitable for treating male erectile dysfunction and other diseases requiring a specific length of line focus treatment.

In addition, the pulse electric energy acting on the coil 5 can be further set to be adjustable, so that the size of the shock wave energy can be adjusted, and the proper shock wave energy can be selected according to different patients and indications; because the physical shape of the diaphragm 3 can be changed, the shock wave beams of divergence, straight line, convergence, point focusing and line focusing can be respectively generated by adopting a convex surface, a plane, a concave surface, a spherical crown surface and a cylindrical section so as to achieve different treatment application purposes.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
