Description

Technical Field

[0001] This utility model relates to the field of non-invasive medical device technology, specifically a piezoelectric focused shock wave device. Background Technology

[0002] Due to continuous advancements in science and technology, the overall trend in disease treatment technology is towards minimally invasive and non-invasive approaches based on accurate targeting. Extracorporeal shock wave therapy (ESWT) is a product of this trend. Because of its non-invasive, non-traumatic, and easily accepted characteristics, ESWT has been widely used in the clinical treatment of musculoskeletal diseases and is hailed as a "bloodless scalpel." Piezoelectric shock waves are a type of ESWT.

[0003] Piezoelectric shock waves utilize hundreds of piezoelectric crystals arranged on a concave surface. When an external electric field passes through the crystals, their volume changes, generating pressure waves; as the crystals return to their original shape, tension waves are generated. All the piezoelectric crystals vibrate together, emitting shock waves simultaneously. These shock waves are collected by a sphere, focusing all the energy onto the treatment site. Piezoelectric ceramic crystals change volume when subjected to voltage, simultaneously generating shock waves. Based on this characteristic of piezoelectric ceramic crystals, devices capable of generating point-focused or linearly focused shock waves can be fabricated; such devices are called piezoelectric focused shock wave devices. Common piezoelectric shock wave devices use electrohydraulic or electromagnetic focusing to generate energy. The focal point of these devices is fixed, but their disadvantages include the need for precise positioning and high operational requirements. Not only is operation inconvenient, but the machine also generates significant noise. Furthermore, the penetration depth of the shock waves often fails to meet the needs of practical applications. Utility Model Content

[0011] Furthermore, both the first driver and the second driver are piezoelectric crystal driving circuits.

[0012] Furthermore, the controller is a microcontroller.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] This piezoelectric shockwave device arranges piezoelectric crystals on a concave surface.

[0015] Figure 1 This is a schematic diagram of the exploded structure of the piezoelectric focusing shock wave device of this utility model;

[0016] Figure 2 This is a block diagram illustrating the principle of the electrical control module of the piezoelectric focusing shock wave device of this utility model. Detailed Implementation

[0017] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0018] like Figure 1 As shown, this utility model proposes a piezoelectric focusing shock wave device, including a decorative shell 1, a light strip 2, an upper cover shell 3, a circuit board 4, a middle shell 5, a button 6, a button plate 7, a lower cover shell 8, a ceramic crystal module 9, a metal conductive shell 10, a gel pad 11, and a fixing outer ring 12. The decorative shell 1 is mounted on the light strip 2, and the light strip 2 is mounted on the upper cover shell 3. The circuit board 4 is installed between the upper cover shell 3 and the middle shell 5. The middle shell 5 is connected to the lower cover shell 8. The ceramic crystal module 9 is installed inside the lower cover shell 8 and is connected to the metal conductive shell 10. The gel pad 11 is installed on the metal conductive shell 10. The fixing outer ring 12 connects the gel pad 11 and the lower cover shell 8 together. The button plate 7 is installed on the side of the middle shell 5, and the button 8 is installed on the outside of the button plate 7.

[0019] like Figure 1 As shown, the ceramic crystal module 9 has a hemispherical concave surface, the part of the metal conductive shell 10 that connects to the ceramic crystal module 9 has a hemispherical concave surface, and the part of the gel pad 11 that connects to the metal conductive shell 10 has a hemispherical concave surface. The hemispherical concave surface is designed to collect and focus the piezoelectric signal energy.

[0020] like Figure 2 As shown, circuit board 4 includes a controller, a first driver, a second driver, and a power supply. Button 8 is electrically connected to the controller, which is electrically connected to the first and second drivers. The first and second drivers are electrically connected to the power supply. The controller sends piezoelectric crystal control signals to the first and second drivers. The first and second drivers amplify the piezoelectric crystal control signals, thereby driving the piezoelectric crystals to work. When the amplified electric field signals from the first and second drivers pass through the piezoelectric crystals, they cause a change in the crystal volume, generating pressure waves; when the crystals return to their original shape, they generate tension waves. All the piezoelectric crystals vibrate together, emitting shock waves, which are collected by the hemispherical concave ceramic crystal module, focusing all the energy onto the treatment site. At least 200 piezoelectric crystals are arranged on the hemispherical concave surface of the ceramic crystal module 9.

[0021] The power supply is a lithium battery or a DC power adapter, providing DC power for the operation of each module. Both the first and second drivers are piezoelectric crystal driver circuits, which are existing technology circuits, generally based on power amplification using transistors or MOSFETs. The controller is a microcontroller that generates piezoelectric control signals, which are then amplified by the driver circuits.

[0022] In summary, this piezoelectric shockwave device arranges 200 piezoelectric crystals on a concave surface. When an external electric field passes through the piezoelectric crystals, the crystal volume changes, generating pressure waves; when the crystals return to their original shape, tension waves are generated. All the piezoelectric crystals vibrate together, emitting shock waves. The energy is collected by the hemispherical concave surface of the ceramic crystal module, focusing all the energy onto the gel pad for non-invasive treatment of the affected area. This stimulates the affected tissue, accelerates new blood vessel growth and blood circulation, and induces a new inflammatory process, thereby awakening the cells' self-repair function. Furthermore, the focused shockwave generates a bubble bursting effect that destroys adhesions, scars, contractures, blockages, and even calcified or fibrotic soft tissue at the site of tendon injuries—commonly known as loosening the injured area—to stimulate soft tissue regrowth, accelerate blood circulation, and promote recovery. Simultaneously, the high-energy shockwave can stimulate pain receptors, blocking pain transmission and achieving immediate pain relief.

[0023] In addition, the gel pads are equipped with various replaceable silicone pad probes, enabling precise and accurate penetration depths. Suitable for pain of varying depths, it meets diverse treatment needs. By changing silicone pad probes of different heights, the device can flexibly adjust the penetration depth of the shockwave, making its treatment focus more precise and meeting the treatment needs of different patients. Its powerful penetrating force allows for effective treatment of deep tissues, expanding the treatment range. As a non-invasive treatment method, focused shockwave therapy eliminates the need for skin incisions or drug injections, greatly reducing patient fear and discomfort and accelerating the recovery process. It avoids the risks and complications of traditional surgery, providing patients with a gentler and more efficient recovery path. Although piezoelectric shockwaves have a high peak pressure at the focal point, their large source aperture angle results in low energy density on the skin surface, reducing pain sensation at the skin surface and rarely causing tissue pain or discomfort. The piezoelectric focused shockwave utilizes inverted hemispherical surface integration technology, combining piezoelectric elements to reduce frequency noise and achieve a focused device, providing a vibration-free, low-noise treatment environment.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
