Description

Technical Field

[0002] Shockwave is a mechanical pulse pressure wave transmitted through physical means. It can produce good therapeutic effects on human tissues. The waveform formation range of shockwave is a very important indicator of shockwave generator. If the waveform formation range of shockwave generator is small, it will directly affect the treatment effect.

[0003] Currently, existing shock wave generators produce shock waves with a small waveform range and a large treatment dead zone. For example, shock wave generators used for treatment in cavities such as the anus and intestines can often only emit shock waves at a small treatment angle, resulting in a small treatment area, low treatment efficiency, and poor treatment effect. Summary of the Invention

[0004] This application provides a shock wave generator and a shock wave therapy device, which aim to solve the above-mentioned technical problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a shock wave generator, which includes a core sleeve, a coil, and a diaphragm.

The projection of the coil in the axial direction of the core sleeve covers at least a portion of the core sleeve, and the projection of the coil in the radial direction of the core sleeve covers at least a portion of the core sleeve. The diaphragm is sleeved on the side of the coil away from the core sleeve. The diaphragm covers at least a portion of the coil in both the axial and radial directions.

[0006] In some embodiments, the shock wave generator includes a first conductive part that passes through a core sleeve, the first conductive part extends in an axial direction and is connected to one end of a coil that covers the core sleeve in the axial direction, and the coil is connected to a first external electrode through the first conductive part.

[0007] In some embodiments, the shock wave generator further includes a second conductive part connected to the end of the coil away from the first conductive part, and the coil is connected to a second external electrode through the second conductive part.

[0008] In some embodiments, the projection of the coil onto the core sleeve in the axial direction completely covers the core sleeve, and the diaphragm completely covers the coil in the axial direction.

[0009] In some embodiments, the core sleeve includes an end portion and a body portion, the body portion extending in an axial direction, at least a portion of the radial dimension of the end portion being smaller than the radial dimension of the body portion, and a coil being wound on the outer peripheral surface of the end portion and the outer peripheral surface of the body portion.

[0010] In some embodiments, the shock wave generator further includes a treatment head having a receiving space having an open end communicating with the outside, and the treatment head being sleeved on the side of the diaphragm away from the coil in an axial direction through the open end.

[0011] In some embodiments, the treatment head and the diaphragm are spaced apart, and the treatment head further includes a dielectric layer that fills the space between the treatment head and the diaphragm for transmitting shock waves generated by the diaphragm and the coil.

[0012] In some embodiments, the shock wave generator further includes a base connected to the treatment head and the core sleeve, respectively, and used to seal the opening end in the axial direction.

[0013] In some embodiments, the medium layer is a liquid medium, and the base is provided with at least two through holes that connect the accommodating space and the outside. The liquid medium can enter the accommodating space through at least one of the through holes and exit the accommodating space through at least one of the other through holes.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a shock wave therapy device, which includes the above-mentioned shock wave generator.

[0015] The beneficial effects of this application's embodiment, which differs from existing technologies, are as follows: It provides a shock wave generator comprising a core sleeve, a coil, and a diaphragm. The coil is wound around the outer circumferential surface of the core sleeve. The projection of the coil in the axial direction of the core sleeve covers at least a portion of the core sleeve, and the projection of the coil in the radial direction of the core sleeve also covers at least a portion of the core sleeve. The diaphragm is sleeved on the side of the coil away from the core sleeve, and the diaphragm covers at least a portion of the coil in both the axial and radial directions. The diaphragm is used to generate shock waves in conjunction with the coil. Through this embodiment, the coil and diaphragm work together to generate shock waves. Since the projections of the coil in both the axial and radial directions of the core sleeve cover at least a portion of the core sleeve, the coil can emit shock waves through both the coil and the diaphragm in both directions.

[0025] Shockwave is a mechanical pulse pressure wave transmitted through physical means. It can produce good therapeutic effects on human tissues. The waveform formation range of shockwave is a very important indicator of shockwave generator. If the waveform formation range of shockwave generator is small, it will directly affect the treatment effect.

[0026] Currently, existing shock wave generators produce shock waves with a small waveform range and a large treatment dead zone. For example, shock wave generators used for treatment in cavities such as the anus and intestines can often only emit shock waves at a small treatment angle, resulting in a small treatment area, low treatment efficiency, and poor treatment effect.

[0027] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the shockwave therapy device provided in this application.

[0028] To address the aforementioned technical problems, this application provides a shockwave therapy device 1, which includes a shockwave generator 2. The shockwave generator 2 generates shockwaves, and the shockwave therapy device 1 can emit shockwaves from the shockwave generator 2 to treat a target object. The shockwave therapy device 1 can directly or indirectly contact the target object through the shockwave generator 2. For example, when the shockwave therapy device 1 treats areas such as the anus, rectum, or vagina, the shockwave generator 2 can be directly inserted into the target cavity to emit shockwaves for treatment, or treatment can be performed by covering the shockwave generator 2 with a sterilization sleeve, etc.

[0029] See Figures 2-4 , Figure 2 This is a schematic diagram of the structure of an embodiment of the shock wave generator provided in this application; Figure 3 It is based on Figure 2 A schematic diagram of shock wave generation in one embodiment of the shock wave generator shown; Figure 4 It is based on Figure 2 An exploded view of an embodiment of the shock wave generator shown.

[0030] This application provides a shock wave generator 2, which includes a core sleeve 10, a coil 20, and a diaphragm 30. The coil 20 is wound around the outer peripheral surface of the core sleeve 10. The projection of the coil 20 in the axial direction x1 of the core sleeve 10 covers at least a portion of the core sleeve 10, and the projection of the coil 20 in the radial direction x2 of the core sleeve 10 also covers at least a portion of the core sleeve 10. The diaphragm 30 is sleeved on the side of the coil 20 away from the core sleeve 10, and the diaphragm 30 covers at least a portion of the coil 20 in both the axial direction x1 and the radial direction x2. The diaphragm 30 is used to generate a shock wave y in conjunction with the coil 20. The core sleeve 10 can be used to provide support for the coil 20 and the diaphragm 30. The coil 20 is wound around the outer peripheral surface of the core sleeve 10. Exemplarily, the coil 20 can have multiple turns, each turn of the coil 20 can surround the outer peripheral surface of the core sleeve 10 once, and the multiple turns of the coil 20 can be arranged sequentially along the axial direction x1 of the core sleeve 10. The material of the core sleeve 10 can be insulating materials, including but not limited to ceramics, engineering plastics, etc. The coil 20 can be made of conductive materials such as copper, and optionally, it can be made of pure copper enameled wire. Optionally, the diameter of the coil 20 can be between 0.3-1 mm, specifically 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, 1 mm, etc. When energized, the coil 20 discharges to generate a pulsed current and forms a strong pulsed magnetic field. According to Lenz's law, the diaphragm 30, fitted onto the coil 20, induces a magnetic field. The magnetic field generated by the diaphragm 30 interacts with the pulsed magnetic field generated by the coil 20, producing a repulsive force that forms a shock wave y. The projection of the coil 20 onto the core sleeve 10 in both the radial direction x2 and the axial direction covers at least a portion of the core sleeve 10. The diaphragm 30 covers at least a portion of the coil 20 in both the axial direction x1 and the radial direction x2. Therefore, the coil 20 and the diaphragm 30 cooperate to form a shock wave y in both the axial direction x1 and the radial direction x2 of the core sleeve 10. The diaphragm 30 is made of materials including, but not limited to, highly conductive metals such as aluminum foil and copper foil, optionally. The thickness of the diaphragm 30 can be between 0.1mm and 0.5mm, specifically, the thickness of the diaphragm 30 can be 0.1mm, 0.2mm, 0.45mm, 0.5mm, etc. In some other application scenarios, the coil 20 can be densely wound on the outer circumferential surface of the core sleeve 10, with each adjacent coil 20 in the multi-turn coil 20 contacting each other in the axial direction x1, so that the projection of the coil 20 on the radial direction x2 of the core sleeve 10 completely covers the core sleeve 10; or, the coil 20 can be densely wound on the outer circumferential surface of the core sleeve 10, with at least a portion of the coils 20 having different radii, so that the projection of the coil 20 on the axial direction x1 of the core sleeve 10 completely covers the core sleeve 10; or, the coil 20 can simultaneously completely cover the core sleeve 10 in both the axial direction x1 and the radial direction x2.Therefore, the coil 20 and the diaphragm 30 work together to generate a shock wave y. The projection of the coil 20 in the axial direction x1 and the radial direction x2 of the core sleeve 10 both cover at least a portion of the core sleeve 10. Thus, the coil 20 can emit shock waves y in both the axial and radial directions x2 of the core sleeve 10 through the coil 20 and the diaphragm 30. The shock wave generator 2 can form shock wave y waveforms in at least the axial direction x1 and the radial direction x2 of the core sleeve 10, thereby expanding the waveform range of the shock wave y and enabling the shock wave generator 2 to treat the target object in multiple directions, thereby improving treatment efficiency.

[0031] In some embodiments, the shock wave generator 2 includes a first conductive part 40, which passes through the core sleeve 10 and extends along the axial direction x1. The first conductive part 40 is connected to one end of the coil 20 that covers the core sleeve 10 in the axial direction x1. The coil 20 is connected to a first external electrode through the first conductive part 40. The first conductive part 40 can be made of conductive materials such as copper or aluminum. In some applications, the core sleeve 10 may be equipped with a mounting hole that extends through the core sleeve 10 in the axial direction x1, and the first conductive part 40 can be inserted into the mounting hole. The first conductive part 40 is connected to one end of the coil 20 that covers the core sleeve 10 in the axial direction x1. For example, the first conductive part 40 can be connected to the outermost turn of the multi-turn coil 20 arranged along the axial direction x1, and the projection of this turn of coil 20 in the axial direction x1 covers the core sleeve 10. The end of the first conductive part 40 away from the coil 20 can be connected to the first external electrode of an external power source. The first external electrode can be an anode electrode or a cathode electrode. Therefore, the first conductive part 40 facilitates the connection between the coil 20 and the external electrode. At the same time, the first conductive part 40 passes through the core sleeve 10 in the first direction, and can apply a tension force in the axial direction x1 to one end of the coil 20 covering the core sleeve 10 in the axial direction x1, thereby reducing the risk of the coil 20 loosening and falling off the outer peripheral surface of the core sleeve 10, and improving the stability of the coil 20.

[0032] In some embodiments, the shock wave generator 2 further includes a second conductive part 50, which is connected to the end of the coil 20 away from the first conductive part 40. The coil 20 is connected to a second external electrode through the second conductive part 50. The second conductive part 50 can be made of conductive materials such as copper or aluminum. Optionally, the material of the second conductive part 50 can be the same as that of the first conductive part 40. It is understood that the coil 20 typically has two ends, with the first conductive part 40 connected to one end and the second conductive part 50 used to connect to the other end. The second conductive part 50 can also be connected to a second external electrode of an external power source. The second external electrode can be an anode electrode or a cathode electrode. It is understood that when the first external electrode is an anode electrode, the second external electrode can be a cathode electrode; or when the first external electrode is a cathode electrode, the second external electrode can be an anode electrode. Thus, the second conductive part 50 and the first conductive part 40 cooperate with each other to form a closed circuit between the coil 20 and the external power source, thereby providing power to the coil 20.

[0033] In some embodiments, the projection of the coil 20 onto the core sleeve 10 in the axial direction x1 completely covers the core sleeve 10, and the diaphragm 30 completely covers the coil 20 in the axial direction x1. Thus, the shock wave y-waveform formed by the coil 20 and the diaphragm 30 can completely cover the core sleeve 10 in the axial direction x1, thereby increasing the coverage range of the shock wave y-waveform, expanding the treatment area, and thus improving treatment efficiency.

[0034] In some embodiments, the core sleeve 10 includes an end portion 11 and a main body portion 12, the main body portion 12 extending in an axial direction x1, at least a portion of the end portion 11 having a radial dimension less than or equal to the radial dimension of the main body portion 12, and a coil 20 wound around the outer peripheral surface of the end portion 11 and the outer peripheral surface of the main body portion 12. The statement that at least a portion of the end portion 11 has a radial dimension less than the radial dimension of the main body portion 12 can mean that the radial dimension at all points on the end portion 11 is less than the radial dimension of the main body portion 12, or it can mean that the radial dimension of a portion of the end portion 11 is less than the radial dimension of the main body portion 12, while the radial dimension of the remaining portion of the end portion 11 is greater than or equal to the radial dimension of the main body portion 12. In some application scenarios, when viewed along the axial direction x1 and gradually away from the main body 12, the radial dimension of at least part of the end portion 11 may have a decreasing trend, that is, the radial dimension of the end portion 11 may gradually change along the axial direction x1. For example, the radial dimension of the end portion 11 near the main body 12 may be the same as the radial dimension of the main body 12, and the radial dimension of the end portion 11 continuously decreases in the axial direction x1 until it reaches the vertex of the end portion 11. In some cases, the radial dimension of the vertex may be so small as to be negligible. In addition, the coil 20 may be wound around the outer peripheral surface of the end portion 11 and the outer peripheral surface of the main body 12. For the coil 20 wound around the outer peripheral surface of the end portion 11, the radial dimension of the coil 20 may decrease in the axial direction x1 as the radial dimension of the end portion 11 decreases. In other embodiments, the projection of the coil 20 in the axial direction x1 may cover one end of the core sleeve 10 and may be connected to the first conductive portion 40 at the vertex. Therefore, the radial dimension of the coil 20 wound on the end 11 and the radial dimension of the coil wound on the main body 12 can be different, so that the diaphragm 30 can form a shock wave y waveform over a larger angle range, thereby improving treatment efficiency. Optionally, the coil 20 can be tightly wound on the end 11 where the radial dimension changes continuously to the apex in the axial direction x1, so that the diaphragm 30 can form a shock wave y waveform in each direction during the change from the radial direction x2 to the axial direction x1.

[0035] In some embodiments, the shock wave generator 2 further includes a treatment head 60, which forms a receiving space 61. The receiving space 61 has an opening 62 communicating with the outside. The treatment head 60 is fitted onto the side of the diaphragm 30 away from the coil 20 along the axial direction x1 through the opening 62. The treatment head 60 may be made of a material with an acoustic impedance similar to that of muscle, including but not limited to polystyrene (TPX), polyurethane, etc., wherein the acoustic impedance value of the treatment head 60 may be between 1×10⁶ kg / (m²·s) and 2×10⁶ kg / (m²·s). The core sleeve 10, the coil 20, and the diaphragm 30 may be housed within the receiving space 61. Thus, the treatment head 60 can provide protection for the components within the receiving space 61, and at the same time, the treatment head 60 can propagate the shock wave y to the outside of the shock wave generator 2 so that the target object receives the shock wave y for treatment.

[0036] In some embodiments, the treatment head 60 is spaced apart from the diaphragm 30. The treatment head 60 also includes a dielectric layer 70, which fills the gap between the treatment head 60 and the diaphragm 30 to conduct the shock wave y generated by the diaphragm 30 and the coil 20. Thus, the diaphragm 30 and the coil 20 cooperate to form the shock wave y, and the dielectric layer 70 can conduct the shock wave y to the treatment head 60.

[0037] In some embodiments, the shock wave generator 2 further includes a base 80, which is connected to the treatment head 60 and the core sleeve 10, and is used to seal the opening end 62 along the axial direction x1. In some applications, the base 80 may also have wiring holes that connect the accommodating space 61 to the outside, so that the first conductive part 40 and the second conductive part 50 can be connected to external electrodes through the wiring holes. Thus, the base 80 can provide support for the core sleeve 10 and the treatment head 60, and at the same time seal the opening end 62, it can also reduce the risk of the dielectric layer 70 escaping from the accommodating space 61, thereby improving the reliability of the shock wave generator 2.

[0038] In some embodiments, the medium layer 70 is a liquid medium 71, and the base 80 is provided with at least two through holes 81 that connect the accommodating space 61 to the outside. The liquid medium 71 can enter the accommodating space 61 through at least one of the through holes 81 and exit the accommodating space 61 through at least one of the remaining through holes 81. The liquid medium 71 can be a liquid including but not limited to water. The liquid medium 71 can serve as a coolant to exchange heat with the coil 20, thereby improving the heat dissipation effect of the coil 20 and extending the life of the coil 20. When the magnetic field generated by the diaphragm 30 repels the pulsed magnetic field generated by the coil 20, the diaphragm 30 can vibrate and strike the liquid medium 71, thereby allowing the liquid medium 71 to conduct the shock wave y to the treatment head 60. In some application scenarios, the temperature of the liquid medium 71 can be arbitrarily set. For example, the temperature of the liquid medium 71 can be set to match the body temperature of the target object, thereby improving the comfort of the shock wave generator 2 during treatment. Liquid medium 71 can enter the receiving space 61 through at least one of the through holes 81 and exit the receiving space 61 through at least one of the remaining through holes 81. For example, there are two through holes 81. Liquid medium 71 can enter the receiving space 61 through either of the two through holes 81 and exit the receiving space 61 through the other of the two through holes 81, thereby forming a backflow and reducing the risk of liquid medium 71 being trapped in the receiving space 61. Understandably, the temperature of the liquid medium 71 can be set according to actual treatment needs to achieve different therapeutic effects. For example, the temperature of the liquid medium 71 can be between 0 degrees Celsius and 20 degrees Celsius. Specifically, the temperature of the liquid medium 71 can be 0 degrees Celsius, 5 degrees Celsius, 15 degrees Celsius, 16.5 degrees Celsius, 20 degrees Celsius, etc., thereby achieving the effect of cryotherapy through the lower temperature of the liquid medium 71. The effects of cryotherapy may include, but are not limited to, inhibiting cell activity, slowing down the conduction of nerve impulses, reducing the sensitivity of nerve endings, relieving pain, constricting blood vessels, reducing capillary permeability, thereby reducing exudation, and alleviating pain caused by tissue swelling compressing nerve endings, etc. In other embodiments, the temperature of the liquid medium 71 may be between 30 degrees Celsius and 50 degrees Celsius. Specifically, the temperature of the liquid medium 71 may be 30 degrees Celsius, 35 degrees Celsius, 46 degrees Celsius, 48.5 degrees Celsius, 50 degrees Celsius, etc., thereby achieving the effect of thermotherapy through the higher temperature of the liquid medium 71. The effect of thermotherapy may include, but is not limited to, reducing the excitability of pain nerves, improving blood circulation, accelerating the elimination of pain-causing substances and absorbing inflammatory exudates, thereby relieving the stimulation and compression of nerve endings, reducing pain, relaxing muscles, enhancing the extensibility of connective tissue, increasing the range of motion of joints, thereby reducing pain caused by muscle spasms or stiffness, and joint ankylosis, etc.

[0039] In some embodiments, the shock wave generator 2 further includes a pressure-resistant diaphragm disposed between the diaphragm 30 and the coil 20, thereby reducing the direct contact and friction between the diaphragm 30 and the coil 20, reducing the risk of damage to the coil 20 or the diaphragm 30 due to long-term friction, and thus improving the service life of the coil 20 and the diaphragm 30.

[0040] In summary, this application provides a shock wave generator 2, which includes a core sleeve 10, a coil 20, and a diaphragm 30. The coil 20 is wound around the outer peripheral surface of the core sleeve 10. The projection of the coil 20 in the axial direction x1 of the core sleeve 10 covers at least a portion of the core sleeve 10, and the projection of the coil 20 in the radial direction x2 of the core sleeve 10 also covers at least a portion of the core sleeve 10. The diaphragm 30 is sleeved on the side of the coil 20 away from the core sleeve 10, and the diaphragm 30 covers at least a portion of the coil 20 in both the axial direction x1 and the radial direction x2. The diaphragm 30 is used to generate a shock wave y in conjunction with the coil 20. Through the above embodiment, the coil 20 and the diaphragm 30 cooperate to generate a shock wave y. The projections of the coil 20 in both the axial direction x1 and the radial direction x2 of the core sleeve 10 cover at least a portion of the core sleeve 10. Therefore, the coil 20 can emit a shock wave y in both the axial and radial directions x2 of the core sleeve 10 through the coil 20 and the diaphragm 30. Therefore, the shock wave generator 2 can generate shock wave y-waveforms at least in the axial and radial directions x2 of the core sleeve 10, thereby expanding the waveform range of the shock wave y-wave. This allows the shock wave generator 2 to treat the target object in multiple directions, thus improving treatment efficiency. Compared with other shock wave generators, the shock wave generator 2 of this application generates a larger shock wave y-waveform range and has higher treatment efficiency.
