[0036] As described in the background section, in the medical and cosmetic fields, injection procedures (such as drug injections and filler injections) typically require skin puncture, causing significant pain to patients. Currently, commonly used local anesthesia methods in clinical practice mainly include topical application of anesthetic creams and injection of local anesthetics. However, topical anesthetic creams require a relatively long onset time, cannot meet the need for immediate anesthesia, and have limited depth of anesthesia, resulting in uneven anesthesia effects at different sites. Injectable local anesthetics require additional injections, increasing patient discomfort.

[0037] See Figures 1 to 7As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a vibration anesthesia device. The vibration anesthesia device includes: a handheld body 10, a vibration module 20, and a microcurrent module. The vibration module 20 is installed on the handheld body 10 and includes a vibration generating component 21 and a vibration head assembly 22.

The vibration head assembly 22 has a contact end for contacting the human body and transmitting vibration to the human body. The microcurrent module includes a microcurrent generating component and an electrode assembly 31. The microcurrent generating component is installed on the handheld body 10 and electrically connected to the electrode assembly 31 for outputting microcurrent to the electrode assembly 31. The electrode assembly 31 is installed on the contact end for contacting the human body and applying microcurrent to the human body. The vibration anesthesia device provided in this embodiment, by setting a vibration module 20 and a microcurrent module on the handheld main body 10, enables doctors to perform rapid, safe, and comfortable non-invasive anesthesia on the human body using a handheld vibration anesthesia device. Specifically, the vibration module 20 in this embodiment can transmit vibration to the human body through the vibration head assembly 22, effectively interfering with the transmission of pain nerve signals. The microcurrent module can apply microcurrent stimulation to the human body through the electrode assembly 31, further inhibiting the transmission of pain nerves. Compared with traditional chemical anesthesia, the vibration anesthesia device provided in this embodiment can achieve immediate physical anesthesia on the human body through the synergistic effect of vibration and microcurrent stimulation, while avoiding the secondary pain caused by injection anesthesia and reducing patient suffering.

[0038] It should be noted that the handheld body 10 in this embodiment refers to a shell structure including a gripping part and an internal accommodating space, and its size is adapted to be held by one hand.

[0039] In some embodiments, the handheld body 10 in this embodiment is made of engineering plastic. Using high-strength, lightweight, and well-insulated engineering plastic to make the handheld body 10 can ensure that the handheld body 10 has good durability and safety.

[0040] See Figure 1 , Figure 2 and Figure 4As shown, in one specific embodiment, the vibration anesthesia device further includes a laser positioning module 40, which is mounted on the handheld body 10 and used to emit a positioning laser onto the human body. The position of the positioning laser corresponds to the vibration action area of ​​the contact end on the human body; and / or, the position of the positioning laser corresponds to the position of the microcurrent action area of ​​the electrode assembly 31 on the human body. By providing the laser positioning module 40 on the handheld body 10, the vibration anesthesia device in this embodiment can use the positioning laser emitted by the laser positioning module 40 to indicate the action area of ​​the vibration head assembly 22 and / or the electrode assembly 31 on the human body, allowing doctors to accurately confirm the anesthesia range before injection, significantly improving the safety and effectiveness of medical operations. It is understood that the laser positioning module 40 in this embodiment can be any suitable laser device capable of emitting a visible positioning laser. Specifically, the laser positioning module 40 can use different types of laser generators, such as semiconductor lasers, fiber lasers, etc., as long as they can generate a clearly visible laser beam for precise positioning.

[0041] See Figures 1 to 5 As shown, in one specific embodiment, the vibration anesthesia device further includes a control module 50. The control module 50 is installed on the handheld main body 10 and electrically connected to the vibration generating component 21, the microcurrent generating component, and the laser positioning module 40, for controlling the operation of the vibration generating component 21, the microcurrent generating component, and the laser positioning module 40. By setting the control module 50 on the handheld main body 10 and electrically connecting the control module 50 to the vibration generating component 21, the microcurrent generating component, and the laser positioning module 40, the vibration anesthesia device can control the operation of the vibration generating component 21, the microcurrent generating component, and the laser positioning module 40 through the control module 50. It can be understood that the control module 50 in this embodiment can regulate the operating frequency of the vibration generating component 21, the microcurrent output intensity and waveform of the microcurrent generating component, and the start / stop status of the laser positioning module 40, so as to achieve precise control of the anesthesia parameters of the vibration anesthesia device, which is beneficial to improving the clinical operation convenience and treatment consistency of the vibration anesthesia device.

[0042] In some embodiments, the control module 50 in this embodiment includes a control circuit board, which is mounted on the handheld body 10 and electrically connected to the vibration generating component 21, the micro current generating component and the laser positioning module 40, for controlling the operation of the vibration generating component 21, the micro current generating component and the laser positioning module 40.

[0043] In some embodiments, the control module 50 of this embodiment further includes an adjustment button assembly and a display assembly. Both the adjustment button assembly and the display assembly are electrically connected to the control circuit board. The adjustment button assembly is used to adjust the vibration frequency of the vibration generating assembly 21 and the microcurrent magnitude of the microcurrent generating assembly, while the display assembly is used to display the vibration frequency of the vibration generating assembly 21 and the microcurrent magnitude of the microcurrent generating assembly. By setting the adjustment button assembly and the display assembly, real-time visual adjustment of the vibration frequency and microcurrent parameters can be achieved, enabling doctors or operators to accurately control the anesthesia state and significantly improving the controllability and safety of the clinical operation of the vibration anesthesia device in this embodiment.

[0044] See Figure 1 and Figure 5 As shown, in one specific embodiment, the vibration anesthesia device further includes a power module 60. The power module 60 is mounted on the handheld body 10 and electrically connected to the control module 50, vibration generating component 21, microcurrent generating component, and laser positioning module 40, providing power to these components. By providing the power module 60 on the handheld body 10 and electrically connecting it to the control module 50, vibration generating component 21, microcurrent generating component, and laser positioning module 40, the vibration anesthesia device can supply power to these components through the power module. It is understood that the power module in this embodiment can provide stable operating voltage and current output to the control module 50, vibration generating component 21, microcurrent generating component, and laser positioning module 40, ensuring the stable operation of each functional module. This allows the vibration anesthesia device to operate independently of external power sources, enabling portable clinical operation and significantly improving its practicality and operational flexibility.

[0045] In some embodiments, the control module 50 in this embodiment further includes a power switch assembly. The power switch assembly in this embodiment is electrically connected to the control circuit board and is used to switch the control power module 60 on and off from the control circuit board, the vibration generating assembly 21, the micro current generating assembly and the laser positioning module 40.

[0046] In some embodiments, the power module 60 includes a rechargeable battery, which is installed in the handheld body 10 and electrically connected to the control module 50, vibration generating component 21, microcurrent generating component, and laser positioning module 40, for supplying power to these components. The rechargeable battery in this embodiment provides stable power support to the control module 50, vibration generating component 21, microcurrent generating component, and laser positioning module 40, enabling long-lasting operation and rapid charging, significantly improving the continuity and convenience of clinical operations.

[0047] In some embodiments, the rechargeable battery in this embodiment is a lithium-ion battery. By setting the rechargeable battery as a lithium-ion battery with high energy density, long cycle life, and no memory effect, the long-term stable operation of the vibration anesthesia device can be guaranteed.

[0048] In some embodiments, the power module 60 in this embodiment is installed at the end of the handheld body 10 away from the vibration head assembly 22. Installing the power module 60 at the end of the handheld body 10 away from the vibration head assembly 22 can balance the overall weight distribution of the vibration anesthesia device to a certain extent, and also facilitates the replacement and maintenance of the power module 60.

[0049] See Figure 1 , Figure 5 and Figure 6 As shown, in one specific embodiment, the vibration anesthesia device further includes a charging module 70. The charging module 70 is installed on the handheld body 10 and electrically connected to the power module 60. An external power source can be electrically connected to the power module 60 through the charging module 70 to charge the power module 60. By providing the charging module 70 on the handheld body 10 and electrically connecting it to the power module 60, the vibration anesthesia device can achieve electrical connection between the external power source and the power module 60 through the charging module 70, thereby enabling the charging operation of the power module 60. This charging operation significantly extends the continuous use time of the vibration anesthesia device and improves its clinical usability.

[0050] In some embodiments, the charging module 70 in this embodiment includes a charging interface, and the charging structure is electrically connected to the power module 60. By providing a charging interface electrically connected to the power module 60, the vibration anesthesia device can achieve rapid and safe energy transfer between an external power source and the power module 60 through the charging interface, thereby improving the charging convenience and continuous use of the vibration anesthesia device.

[0051] In some embodiments, the charging interface in this embodiment is a USB-Type C interface. By setting the charging interface to a USB-Type C interface, the vibration anesthesia device can achieve efficient and safe energy transfer through the bidirectional plug-and-play feature and fast charging protocol support of the USB-Type C interface, significantly improving the charging convenience and reliability of the vibration anesthesia device.

[0052] In one specific embodiment, the vibration generating component 21 includes a vibration motor, and the vibration head component 22 has a clamping end. The vibration head component 22 is detachably mounted to the output shaft of the vibration motor via the clamping end. By making the clamping end of the vibration head component 22 detachably connected to the output shaft of the vibration motor, it is possible to ensure efficient transmission of vibration energy to the contact end while facilitating quick replacement and convenient maintenance of the vibration head component 22 in the vibration anesthesia device, effectively improving the operational flexibility and clinical efficiency of the vibration anesthesia device.

[0053] In some embodiments, the vibration motor in this embodiment is a magnetic levitation acoustic motor. It is understood that the magnetic levitation acoustic motor in this embodiment includes an output shaft with a built-in permanent magnet and two electromagnetic coils located on both sides of the output shaft. After the electromagnetic coils are energized, they can generate a controllable electromagnetic field that interacts with the permanent magnet, creating a contactless magnetic levitation state between the output shaft with the built-in permanent magnet and the electromagnetic coils. When the magnetic levitation acoustic motor is electrically connected to the control module 50, the control module 50 can switch the current direction of the electromagnetic coils on both sides, causing the polarity of the electromagnetic field generated by the electromagnetic coils to change alternately. At this time, the permanent magnet built into the output shaft will generate periodic repulsive and attractive forces with the electromagnetic coils on both sides, thereby driving the permanent magnet to reciprocate.

[0054] In some embodiments, the vibrating head assembly 22 in this embodiment includes a vibrating head handle and a vibrating head body, wherein the vibrating head body is disposed at the end of the vibrating head handle away from the handheld body 10, wherein the vibrating head handle forms the handle end of the vibrating head assembly 22, and the vibrating head body forms the contact end of the vibrating head assembly 22.

[0055] In some embodiments, the vibrating head clamp is provided with a first quick-release connection structure, and the output shaft of the vibrating motor is provided with a second quick-release connection structure. The vibrating head clamp and the output shaft of the vibrating motor are detachably connected through the cooperation of the first and second quick-release connection structures. Through the complementary cooperation of the first quick-release connection structure of the vibrating head clamp and the second quick-release connection structure of the vibrating motor output shaft, rapid assembly and disassembly of the vibrating head assembly 22 and the vibrating head generating assembly can be achieved. While ensuring the efficiency of vibration energy transmission, it supports plug-and-play replacement of vibrating head assemblies 22 of different specifications, significantly improving the clinical operation efficiency and maintenance convenience of the vibration anesthesia device. It is understood that the first and second quick-release connection structures in this embodiment can be any structure capable of quick-release connection, such as a snap-fit ​​connection structure, a magnetic connection structure, a threaded quick-release structure, or a cam locking structure, as long as they can meet the functional requirements of reliable connection and rapid disassembly between the vibrating head assembly 22 and the vibrating motor output shaft.

[0056] In some embodiments, the end of the vibrating head body away from the handheld body 10 has a skin contact surface, and the vibrating head body contacts the human body through the skin contact surface. It is understood that when administering local anesthesia to the injection area of ​​the human body using the vibration anesthesia device of this embodiment, the vibrating head body presses against the injection area through the skin contact surface to ensure that the vibration energy on the vibrating head body can be effectively transferred to the injection area.

[0057] In some embodiments, the outer contour shape of the skin contact surface in this embodiment is one of a fan shape, a T shape, and an arc shape. Setting the outer contour shape of the skin contact surface in this embodiment to one of a fan shape, a T shape, and an arc shape allows the vibration anesthesia device to select an appropriate skin contact surface shape according to different treatment sites, ensuring high transmission efficiency of vibration energy and uniform distribution of contact pressure, thereby effectively improving the accuracy of the anesthetic effect of the vibration anesthesia device and the patient's comfort.

[0058] In some embodiments, the vibrating head body in this embodiment is made of stainless steel. Using stainless steel to make the vibrating head body can give the vibrating head body a certain heat dissipation capacity, and at the same time reduce the risk of microcurrent leakage on the electrode assembly 31 to a certain extent.

[0059] In some embodiments, the vibrating head body in this embodiment is made of 316 stainless steel.

[0060] In some embodiments, the outer side of the vibrating head body is covered with an elastic material layer. By using this elastic material layer, the vibrating head body can reduce the contact pressure between itself and the human body through the buffering properties of the elastic material layer, improving the uniformity of vibration transmission and effectively enhancing patient comfort while ensuring effective anesthesia depth.

[0061] In some embodiments, the elastic material layer in this embodiment is made of soft silicone.

[0062] In some embodiments, the total thickness of the vibrating head body and the elastic material layer in this embodiment is 1.5 mm. Setting the total thickness of the vibrating head body and the elastic material layer to 1.5 mm can ensure efficient transmission of vibration energy while providing sufficient flexible buffering, achieving a good balance between treatment comfort and anesthetic effectiveness.

[0063] See Figure 7 As shown, in one specific embodiment, the electrode assembly 31 includes at least one electrode piece with an electrode positioning recess on its contact end. The electrode piece is installed in the electrode positioning recess and electrically connected to the microcurrent generating component. By providing an electrode positioning recess on the contact end and installing the electrode piece within it, reliable positioning of the electrode piece can be achieved, preventing displacement and ensuring that the microcurrent on the electrode piece can be stably conducted to the target tissue area of ​​the human body. This significantly improves the accuracy and safety of the anesthetic effect of the vibration anesthesia device.

[0064] In some embodiments, the electrode assembly 31 in this embodiment includes multiple electrode pads, with multiple electrode positioning recesses spaced apart on the contact ends, and the multiple electrode pads corresponding one-to-one with the multiple electrode positioning recesses. By providing multiple electrode pads, the anesthesia coverage area of ​​the electrode assembly 31 can be expanded, and the uniformity and reliability of the anesthetic effect of the vibration anesthesia device can be improved.

[0065] In some embodiments, the electrode pads in this embodiment are made of conductive silicone. By using soft, highly conformable conductive silicone to make the electrode pads, they can fully conform to the skin, ensuring effective transmission of microcurrents.

[0066] In some embodiments, the electrode pad in this embodiment has multiple anti-slip protrusions on the side away from the contact end. By providing anti-slip protrusions, the contact area and friction between the electrode pad and human skin can be increased, preventing the electrode pad from shifting during operation.

[0067] In some embodiments, the electrode assembly 31 in this embodiment further includes a wire, and the microcurrent generating assembly and the electrode sheet are electrically connected by the wire.

[0068] In some embodiments, the microcurrent generating component in this embodiment includes a microcurrent generator electrically connected to the electrode plate for outputting a microcurrent to the electrode plate. It is understood that the microcurrent generator in this embodiment can be any suitable device capable of generating a precise and controllable microcurrent, such as a programmable current source chip, a constant current circuit module, or a digitally controlled current generator.

[0069] In some embodiments, the size and outer contour shape of the electrode sheet in this embodiment are adapted to the injection area. For example, when the injection area is located in the eye of the human body, the outer contour shape of the electrode sheet in this embodiment can be semi-arc; when the injection area is located in the face of the human body, the outer contour shape of the electrode sheet in this embodiment can be ring-shaped; when the injection area is located in the body of the human body, the outer contour shape of the electrode sheet in this embodiment can be elongated, etc.

[0070] In some embodiments, the electrode positioning recess in this embodiment is disposed on the skin contact surface. When the vibrating head body presses the injection area through the skin contact surface, the electrode plate installed on the electrode positioning recess can be pressed on the injection area together with the skin contact surface to ensure that the microcurrent on the electrode plate can be effectively transmitted to the injection area.

[0071] In some embodiments, the positioning laser in this embodiment passes through the center of the contact end. By setting the positioning laser to pass through the center of the contact end, it is possible to ensure that the laser positioning point precisely coincides with the vibration and electrical stimulation areas, thereby improving the controllability and safety of the clinical operation of the vibration anesthesia device.

[0072] In some embodiments, a laser clearance area is provided on the skin contact surface in this embodiment. The center of the laser clearance area coincides with the center of the contact end. When the vibrating head body presses the injection area through the skin contact surface, the positioning laser irradiates the injection area through the laser clearance area. By providing a laser clearance area on the skin contact surface, it can be ensured that the positioning laser can still directly shine on the injection area without obstruction when the contact end is pressed on the injection area, effectively improving the positioning continuity of the positioning laser during the injection process.

[0073] In one specific embodiment, the vibration frequency of the contact end is 10,000 to 48,000 times per minute. The vibration anesthesia device in this embodiment sets the vibration frequency of the contact end to 10,000 to 48,000 times per minute, achieving a gradient vibration anesthesia effect. Specifically, when the vibration frequency of the contact end is 10,000 times per minute, the vibration energy transmitted to the human body can effectively interfere with the transmission of pain nerve signals, producing a relatively significant analgesic effect. When the vibration frequency of the contact end is 480,000 times per minute, the vibration energy transmitted to the human body can meet the anesthesia needs of deep tissues while avoiding tissue damage. The vibration frequency of 10,000 to 48,000 times per minute ensures that the vibration energy is sufficient to interfere with the transmission of pain nerves while avoiding tissue damage. Furthermore, different vibration frequencies can selectively anesthetize different tissue depths such as the skin and subcutaneous tissue, achieving a good balance between safety and anesthetic effect.

[0074] It is understandable that the high-frequency vibration of 10,000 to 48,000 times per minute in this embodiment can stimulate the nerve endings of the human skin, interfere with the transmission of pain signals, and thus reduce the pain of injection needle puncture.

[0075] In one specific embodiment, the microcurrent of the electrode assembly 31 is 100μA to 800μA. Setting the microcurrent on the electrode assembly 31 to 100μA to 800μA enables safe and effective microcurrent stimulation anesthesia. Specifically, when the microcurrent on the electrode assembly 31 is 100μA, the microcurrent applied to the human body by the electrode assembly 31 effectively inhibits the conduction of pain nerves, producing a relatively obvious analgesic effect. When the microcurrent on the electrode assembly 31 is 800μA, the microcurrent applied to the human body by the electrode assembly 31 further inhibits the conduction of pain nerves, meeting the anesthesia requirements for high pain thresholds. The microcurrent of 100μA to 800μA ensures that the electrical stimulation is sufficient to inhibit the conduction of pain nerves while avoiding tissue damage. Adjusting the magnitude of the microcurrent can achieve adaptive adjustment for different pain sensitivities, ensuring a good balance between safety and anesthetic effect.

[0076] It is understood that the micro-current stimulation of 100μA to 800μA in this embodiment can further block pain transmission. Through the synergistic effect of microcurrent stimulation and high-frequency vibration, the immediate analgesic and anesthetic effect of the vibration anesthesia device can be enhanced.

[0077] In one specific embodiment, the wavelength of the positioning laser is 492nm to 625nm. Setting the wavelength of the positioning laser to the visible spectrum range of 492nm to 625nm ensures the visibility of the positioning laser under various skin color conditions. Specifically, when the wavelength of the positioning laser is in the blue-green light band of 492nm to 520nm, the positioning laser has high reflectivity in the human body surface tissue and can clearly mark the positioning point on the skin surface. When the wavelength of the positioning laser is in the yellow-green light band of 520nm to 580nm, the positioning laser has optimal blood vessel avoidance characteristics. When the wavelength of the positioning laser is in the red-orange light band of 580nm to 625nm, the positioning laser can achieve transmission to superficial tissues of 1 to 2mm under the skin.

[0078] It is understandable that the positioning laser with a wavelength of 492nm to 625nm in this embodiment can form clear light spots on human skin, providing doctors with precise injection positioning references.

[0079] In some embodiments, when a doctor prepares to perform an injection, they first turn on the power switch of the vibration anesthesia device. Then, by adjusting the button assembly, they select to activate either high-frequency vibration or microcurrent stimulation, or both functions can be activated simultaneously. After the vibration motor and / or microcurrent generator starts working, the contact end of the vibration head assembly 22 can be pressed against the patient's injection site to stimulate the skin, achieving immediate analgesia. Simultaneously, the doctor can activate the laser positioning module 40 as needed to determine the injection point by positioning the laser on the skin. During the injection process, continuous high-frequency vibration and microcurrent stimulation continuously reduce the patient's pain. The doctor can accurately insert the injection needle into the target location based on the positioning laser, achieving simultaneous injection and anesthesia. The high-frequency vibration and microcurrent stimulation functions work instantly upon injection, effectively reducing patient pain and avoiding the long waiting time associated with traditional anesthesia methods, thus improving the patient's experience. The positioning laser provides clear injection positioning assistance to the doctor, significantly reducing the possibility of injection site deviation, improving the accuracy of medical injections, and contributing to enhanced treatment outcomes.

[0080] In some embodiments, when assembling the vibration anesthesia device in this embodiment, the power module 60 and the control module 50 are first installed inside the handheld body 10, and the various functional modules are electrically connected by wires. The vibration motor and the microcurrent generator are installed inside the handheld body 10 and connected to the control module 50. The laser positioning module 40 is installed on the side of the front end of the handheld body 10 (the end where the vibration head assembly 22 is installed) and connected to the corresponding control line. Finally, the vibration head assembly 22 is assembled with the handheld body 10 to ensure that the connection is firm and well sealed to prevent dust and liquid from entering and affecting the performance of the vibration anesthesia device.

[0081] In some embodiments, before using the vibration anesthesia device of this embodiment for local anesthesia, the doctor needs to check whether the vibration anesthesia device has sufficient power and whether each function is normal. When using it, the contact end of the vibration head assembly 22 is aligned with the injection site of the patient, the power switch assembly is turned on, and the vibration and microcurrent stimulation functions are started in sequence. The vibration frequency and microcurrent intensity are adjusted according to the patient's response. Then the laser positioning module 40 is turned on, the injection point is determined, and the injection operation is performed. During the injection process, the vibration and microcurrent stimulation functions are kept on until the injection is completed.

[0082] In some embodiments, the vibration anesthesia device in this embodiment has a variety of preset operating modes, such as modes for different areas of the face (forehead, cheeks, chin, etc.) and modes for different injection types (filler injection, wrinkle removal injection, etc.). The frequency, intensity and stimulation time of the microcurrent in each mode are preset, and medical staff can also make fine adjustments based on the preset modes according to the actual situation.

[0083] In summary, the vibration anesthesia device provided in this embodiment has at least the following beneficial technical effects: The vibration anesthesia device provided in this embodiment, by setting a vibration module 20 and a microcurrent module on the handheld main body 10, enables doctors to perform rapid, safe, and comfortable non-invasive anesthesia on the human body using the handheld vibration anesthesia device.
