Description

Technical Field

[0001] This invention relates to the field of shockwave handles, and more specifically, to an electromagnetic zoom shockwave handle. Background Technology

[0002] Extracorporeal shock wave therapy (ESWB) utilizes generators such as electrohydraulic, piezoelectric, or electromagnetic generators to produce pulsed sound waves with high voltage, short duration, and wide frequency band. The direct mechanical impact effect of the pulsed sound waves and the indirect mechanical effect produced by cavitation disrupt the microstructure of ischemic tissue, initiating or promoting physiological repair processes, thereby achieving a therapeutic effect. Electromagnetic generators, in particular, generate shock waves by vibrating a metal diaphragm in a medium such as water or air. The diaphragm vibrates due to the pulsed magnetic field generated by a connected energized coil, which propels it. While the energy produced is lower than that of electrohydraulic generators, it is quieter, requires no electrode replacement, and its plane wave characteristics minimize tissue damage.

[0003] Currently, existing electromagnetic shock wave sources generate a strong pulsed magnetic field by discharging an inductor coil through a high-voltage capacitor. This pulsed current induces a magnetic field on the diaphragm covering the coil. The magnetic field of the diaphragm interacts with the magnetic field of the coil to generate a repulsive force, forming a shock wave on the other side of the diaphragm in the medium. This shock wave is then focused by a lens to generate a self-focused shock wave.

[0004] However, traditional electromagnetic wave sources, especially split-type self-focusing electromagnetic wave sources, have separate components for the coil and metal diaphragm. Installation requires extremely strict control, making it difficult to guarantee the relative position of the coil and diaphragm. This results in a large focal point drift range and poor focal point stability. Furthermore, because different patients require different treatment locations or depths, different shockwave therapy heads need to be used, which is inconvenient. Summary of the Invention

[0005] In order to solve the problems existing in the background art, the present invention proposes an electromagnetic zoom shockwave handle.

[0006] An electromagnetic zoom shockwave handle includes a handle body, an electromagnetic excitation mechanism, an electromagnetic generating mechanism, an electromagnetic induction mechanism, and a variable focusing mechanism. The handle body contains a power module and a control unit. The electromagnetic excitation mechanism is located at one end of the handle body. The control unit controls and connects to the electromagnetic excitation mechanism. The electromagnetic excitation mechanism drives and connects to the electromagnetic generating mechanism. The electromagnetic generating mechanism drives and connects to the electromagnetic induction mechanism. The electromagnetic induction mechanism drives and connects to the variable focusing mechanism.

[0007] Based on the above, the electromagnetic excitation mechanism includes an LC oscillation excitation circuit, which includes resistors RB1, RB2, RC, RE, capacitors CC, CE, CB, C, inductors L1 and L2, and a transistor VT. The base of transistor VT is connected to AC power supply EC through resistor RB1 and grounded through resistor RE. The emitter of transistor VT is grounded through resistor RE and capacitor CE, respectively. The collector of transistor VT is connected to AC power supply EC through resistor RC. The collector of transistor VT is also connected to one end of inductor L1 and one end of capacitor C through capacitor CC. The other end of inductor L1 is grounded and connected to one end of inductor L2. The other end of inductor L2 is connected to the other end of capacitor C and then grounded through capacitor CB and resistor RB2.

[0008] Based on the above, the electromagnetic generating mechanism includes a coil, an insulating fixing component, and a conductive fixing component. The insulating fixing component is disposed on the handle body and has a through hole. The conductive fixing component passes through the through hole. The end of the coil is electrically connected to and fixedly disposed at one end of the conductive fixing component, and the other end of the conductive fixing component is electrically connected to the electromagnetic excitation mechanism.

[0009] Based on the above, the electromagnetic induction mechanism includes a first annular component, a second annular component, and a metal diaphragm. One end of the first annular component is provided with an annular stop. The second annular component is detachably sleeved inside the first annular component, and the first annular component is used to press the metal diaphragm against the annular stop. The electromagnetic generating mechanism drives the metal diaphragm.

[0010] Based on the above, the variable focusing mechanism includes a first cylinder and a second cylinder, which are respectively open at one end and closed at the other end. The cylinder walls of the first cylinder and the second cylinder are respectively provided with cavities. The cylinder wall of the second cylinder is inserted into the cavity of the cylinder wall of the first cylinder, and the cavity of the second cylinder is connected to the cavity of the first cylinder. An elastic diaphragm is provided at the bottom of the inner side wall of the first cylinder, and a connecting hole is provided at the bottom of the inner side wall of the first cylinder to connect with the cavity of the side wall of the first cylinder. A liquid medium is filled between the cavity of the side wall of the first cylinder, the cavity of the side wall of the second cylinder, the diaphragm, and the bottom of the first cylinder.

[0011] Based on the above, the inner wall of the first cylinder and the end of the second cylinder are respectively provided with expansion seals.

[0012] Based on the above, a magnetic component is provided at the bottom of the second cylinder, and an electromagnet is provided between the second cylinder and the electromagnetic induction mechanism. The electromagnet is electrically connected to the control switch and control circuit inside the handle body.

[0013] Based on the above, the extensible seal is a rubber membrane with a certain degree of flexibility.

[0014] Based on the above, an end cap is provided at one end of the handle body, and the end cap covers the electromagnetic excitation mechanism, electromagnetic generation mechanism, electromagnetic induction mechanism and variable focusing mechanism on the handle.

[0015] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention achieves variable focusing by cooperating with an electromagnetic excitation mechanism, an electromagnetic generation mechanism, an electromagnetic induction mechanism, and a variable focusing mechanism. In particular, the variable focusing mechanism enables variable focusing, allowing a single treatment head to simultaneously and accurately reach trigger points at different depths. This effectively detects deep, latent trigger points that cannot be found by physical examination. The treatment depth is dynamically controlled, and there is no need to change the treatment head.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1As shown, an electromagnetic zoom shockwave handle includes a handle body 1, an electromagnetic excitation mechanism 2, an electromagnetic generating mechanism 3, an electromagnetic induction mechanism 4, and a variable focusing mechanism 5. The handle body 1 is equipped with a power module and a control unit. The electromagnetic excitation mechanism 2 is located at one end of the handle body 1. The control unit controls and connects to the electromagnetic excitation mechanism 2. The electromagnetic excitation mechanism 2 drives and connects to the electromagnetic generating mechanism 3. The electromagnetic generating mechanism 3 drives and connects to the electromagnetic induction mechanism 4. The electromagnetic induction mechanism 4 drives and connects to the variable focusing mechanism 5.

[0024] In use, a voltage pulse is used to charge the electromagnetic generating mechanism 3 via the electromagnetic excitation mechanism 2, thereby generating a magnetic field. In turn, the electromagnetic induction mechanism 4 generates a reverse induced current and an induced magnetic field. The magnetic field and the reaction magnetic field can repel each other, causing the device in the electromagnetic induction mechanism 4 to vibrate rapidly and generate a shock wave. Then, a variable focusing mechanism 5 is used to focus the generated shock wave.

[0025] Specifically, such as Figure 2 As shown, the electromagnetic excitation mechanism 2 includes an LC oscillation excitation circuit. This circuit comprises resistors RB1, RB2, RC, and RE, capacitors CC, CE, CB, and C, inductors L1 and L2, and a transistor VT. The base of transistor VT is connected to the AC power supply EC via resistor RB1 and grounded via resistor RE. The emitter of transistor VT is grounded via resistor RE and capacitor CE. The collector of transistor VT is connected to the AC power supply EC via resistor RC. The collector of transistor VT is also connected to one end of inductor L1 and one end of capacitor C via capacitor CC. The other end of inductor L1 is grounded and connected to one end of inductor L2. The other end of inductor L2 is connected to the other end of capacitor C and then grounded via capacitor CB and resistor RB2. In practice, a connector is provided on the handle for connecting to AC power. When the AC power supply EC is connected, transistor VT conducts and cuts off at a certain frequency, generating a changing current in inductors L1 and L2, which in turn induces a current in the coil of the electromagnetic generator.

[0026] like Figure 3As shown, the electromagnetic generating mechanism 3 includes a coil 31, an insulating fixing member 32, and a conductive fixing member 34. The insulating fixing member 32 is disposed on the handle body 1, and a through hole 33 is formed in the insulating fixing member 32. The conductive fixing member 34 passes through the through hole 33. One end of the coil 31 is electrically connected to and fixedly disposed on one end of the conductive fixing member 34, and the other end of the conductive fixing member 34 is electrically connected to the electromagnetic excitation mechanism 2. The insulating fixing member 32 is fixed to one end of the handle body 1, and the coil 31 is fixed to the insulating fixing member 32 through the conductive fixing member 34, and is electrically connected to the LC oscillation excitation circuit through the conductive fixing member 34. The current of the LC oscillation excitation circuit causes the coil 31 to generate a magnetic field.

[0027] like Figure 4 As shown, the electromagnetic induction mechanism 4 includes a first annular component 41, a second annular component 44, and a metal diaphragm 43. One end of the first annular component 41 is provided with an annular stop 42. The second annular component 44 is detachably fitted inside the first annular component 41, and the first annular component 41 is used to press the metal diaphragm 43 against the annular stop 42. The electromagnetic generating mechanism 3 drives the metal diaphragm 43. In reality, one end of the handle body 1 is provided with an end cap, which presses the first annular component 41 against one end of the handle body 1, or the outer wall of the first annular component 41 is fitted with the inner wall of the end cap, thus fixing it inside the end cap. The second annular component 44, in conjunction with the annular stop 42 of the first annular component 41, fixes the edge portion of the metal diaphragm 43 onto the first annular component 41. After the coil 31 generates a magnetic field, a reverse induced current is generated in the metal diaphragm 43. The magnetic fields formed by the current in the coil 31 and the current in the metal diaphragm 43 repel each other, causing the metal diaphragm 43 to move rapidly. After the current in coil 31 is disconnected, the metal diaphragm 43 returns to its original position. By repeatedly switching the current on and off, the metal diaphragm 43 can repeatedly move rapidly and return to its original position. In other words, the metal diaphragm 43 can vibrate rapidly to generate shock waves.

[0028] like Figure 5As shown, the variable focusing mechanism 5 includes a first cylinder 51 and a second cylinder 52. The first cylinder 51 and the second cylinder 52 are respectively open at one end and closed at the other. The walls of the first cylinder 51 and the second cylinder 52 are respectively provided with cavities. The wall of the second cylinder 52 is inserted into the cavity of the first cylinder 51, and the cavity of the second cylinder 52 communicates with the cavity of the first cylinder 51. An elastic diaphragm 53 is provided at the bottom of the inner wall of the first cylinder 51, and a connecting hole 57 is provided at the bottom of the inner wall of the first cylinder 51, communicating with the cavity of the side wall of the first cylinder 51. A liquid medium is filled between the cavity of the side wall of the first cylinder 51, the cavity of the side wall of the second cylinder 52, the diaphragm, and the bottom of the first cylinder 51. Because the diaphragm 53 and the bottom of the first cylinder 51 are filled with a liquid medium, the diaphragm 53, the liquid medium, and the bottom of the first cylinder 51 form a lens-like structure. The second cylinder 52 is movably inserted into the cylinder wall of the first cylinder 51. When the second cylinder 52 approaches the first cylinder 51, the space between the cylinder walls of the second cylinder 52 and the first cylinder 51 is reduced. The liquid medium inside enters the space between the diaphragm and the bottom of the first cylinder 51 through the connecting hole 57, thereby squeezing the diaphragm 53 to deform and change its curvature, thereby adjusting the focus of the passing shock wave.

[0029] In practice, the inner wall of the first cylinder 51 and the end of the second cylinder 52 are respectively provided with telescopic seals 54. In this embodiment, the telescopic seal 54 is a flexible rubber membrane used to seal the movable parts of the side walls of the first cylinder 51 and the second cylinder 52 to prevent the filled liquid medium from flowing out. The inner wall of the first cylinder 51 and the inner wall of the cavity of the second cylinder 52 fit together to facilitate movement while ensuring that the first cylinder 51 and the second cylinder 52 move coaxially during movement. In reality, the bottom of the first cylinder 51, the bottom of the second cylinder 52, and the membrane are all made of transparent material.

[0030] A magnetic component, such as a magnet 55, is provided at the bottom of the second cylindrical body 52. ​​An electromagnet 56 is provided between the second cylindrical body 52 and the electromagnetic induction mechanism 4. The electromagnet 56 is electrically connected to the control switch and control circuit inside the handle body 1. In practice, the electromagnet 56 is located on the inner wall of the end. When the electromagnet 56 is energized, it generates magnetism, which repels the magnetic component, causing the second cylindrical body 52 to move towards the first cylindrical body 51; and attracts the magnetic component, causing the second cylindrical body 52 to move away from the first cylindrical body 51.

[0031] In practice, for aesthetic and convenience purposes, the outermost sidewall of the first cylinder 51 can be extended, so that the first cylinder 51 as a whole serves as an end cap. Alternatively, an additional end cap can be provided, and the first cylinder 51 can be fixed inside the end cap.
