Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency micro-needle treatment, in particular to a micro-needle treatment device. Background Art

[0002] Radio frequency microneedle therapy device is a common beauty device used to destroy fat layer cells. Radio frequency microneedle is to send radio waves into the subcutaneous tissue through the radio frequency therapy device, so that the fat particles in the subcutaneous tissue move and generate heat energy. It uses the principle that the collagen fibers in the dermis will immediately contract at 55℃-65℃ and the principle of radio wave skin tightening, which has the two functions of lifting the skin and promoting collagen regeneration. While the collagen produces immediate contraction, it will also stimulate the dermis to secrete more new collagen fibers to regenerate, thereby supporting the skin's scaffold again, increasing the thickness and density of the dermis, filling wrinkles, and improving sagging.

[0003] During the treatment process, the radiofrequency microneedle needs to penetrate the skin so that the needle tip can reach a certain subcutaneous depth accurately to produce a better treatment effect. However, due to the complexity of the human epidermis, the radiofrequency microneedle needs to be lifted by the operator to achieve this effect during use, resulting in different effects for operators with different proficiency. Therefore, the market has begun to use negative pressure to lift and flatten the skin to achieve a better treatment effect, thereby reducing the technical requirements for operators and facilitating the treatment effect and product promotion.

[0004] During the radio frequency microneedle treatment process, the needle body needs to be inserted into the skin. The treated subject will feel pain when the needle body enters the skin, and the intensity of the pain is related to the speed of needle removal. The faster the needle removal speed, the milder the pain, and the slower the needle removal speed, the stronger the pain.

[0005] In specific applications, most radio frequency microneedle treatment devices on the market use a screw stepper motor to directly drive the microneedle assembly to achieve needle removal. However, the needle removal speed is slow, causing the treated person to experience greater pain during treatment, and the device cannot automatically reset when the power is off.

DETAILED DESCRIPTION

However, it should be understood that these physical details should not be used to limit the present invention.

They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0021] See also Figure 1 As shown, the embodiment of the utility model provides a microneedle treatment device, including: a microneedle assembly 1, a limiting device 2 and a driving device 3. Among them, the driving device 3 includes a driver 31 and a driving rod 32, and the driving rod 32 is movably arranged in the driver 31. The driver 31 can drive the driving rod 32 to move rapidly and linearly in the driver 31, thereby driving the microneedle assembly 1 to achieve rapid needle removal. The limiting device 2 includes a limiting rod 21 that can output linear displacement and a limiting connector 4. The limiting connector 4 is arranged at the end of the limiting rod 21, and the limiting connector 4 can move synchronously with the limiting rod 21. One end of the driving rod 32 is connected to the limiting connector 4, and the other end is connected to the microneedle assembly 1. The linear displacement output by the limiting device 2 is the limiting stroke of the limiting connector 4, and the limiting stroke determines the needle removal depth of the microneedle assembly 1. The limiting connector 4 allows the driving rod 32 to move linearly within the limiting stroke.

[0022] Specifically, the limit connector 4 includes a static limit member 41 and a movable limit member 42. The movable limit member 42 can move linearly relative to the static limit member 41. The static limit member 41 is connected to the limit rod 21 (for example, a detachable fixed connection such as a threaded connection, a snap connection, or a non-detachable fixed connection such as welding or bonding), and the movable limit member 42 is connected to the drive rod 32 (for example, a detachable fixed connection such as a threaded connection, a snap connection, or a non-detachable fixed connection such as welding or bonding).

[0023] A first stopper 411 is provided on the stationary limiter 41, and a second stopper 4121 is provided on the movable limiter 42. When the driving rod 32 drives the movable limiter 42 to move until the first stopper 411 contacts the second stopper 421, the first stopper 411 will prevent the movable limiter 42 from moving, forcing the driving rod 32 to stop moving, thereby stopping the microneedle assembly 1 from removing the needle, thereby ensuring the accuracy of the needle removal depth.

[0024] The static limiting member 41 is provided with a spatial structure, and the static limiting member 41 allows the movable limiting member 42 to move freely within the spatial structure, and at least a part of the movable limiting member 42 is provided within the spatial structure so that the movable limiting member 42 can move linearly relative to the static limiting member 41. The first stopper 411 is provided at one end of the static limiting member 41 close to the driving device 3, and the second stopper 421 is provided at one end of the movable limiting member 42 close to the limiting device 2.

[0025] Specifically, the static limit member 41 is a limit sleeve, and a movable cavity 412 is provided in the limit sleeve. The movable limit member 42 is movably provided in the movable cavity 412 of the limit sleeve, and the length of the movable cavity 412 of the limit sleeve can allow the movable limit member 42 to move within the entire limit stroke. The first stop member 411 is provided on the side wall of the movable cavity 412 at one end close to the driving device 3, and the circumferential side wall of the movable limit member 42 extends to form a second stop member 421.

[0026] The movable limit member 42 can be configured as a T-shaped limit block, the upper lateral extension portion of the movable limit member 42 forms a second stop member 421, and the lower vertical portion of the movable limit member 42 passes through the limit sleeve and is connected to the drive rod 32, such as a threaded connection.

[0027] In addition, a slide groove or a guide groove may be provided on the static limiting member 41 to form a spatial structure allowing the movable limiting member 42 to move freely, and a slider or a guide block adapted to be connected with the slide groove or the guide groove may be provided on the movable limiting member 42, so that the movable limiting member 42 can move linearly along the slide groove or the guide groove relative to the static limiting member 41. The first stopper 411 is provided on one end of the slide groove or the guide groove close to the driving device 3, and the second stopper 421 is provided on one end of the slider or the guide block close to the limiting device 2.

[0028] The limiting device 2 includes a motor 23, a screw 22 and a limiting rod 21. The screw 22 is disposed in the motor 23, and the limiting rod 21 is fixedly connected or integrally disposed with the screw 22. The motor 23 drives the screw 22 to output reciprocating linear motion and output linear displacement, so that the screw 22 drives the limiting connector 4 to synchronously move linearly to adjust the limiting stroke of the limiting connector 4.

[0029] The microneedle treatment device also includes a shell 5, and a mounting frame 51 is provided inside the shell 5. The mounting frame 51 is fixed on the inner wall of the shell 5, and the motor 23 is fixed on the mounting frame 51. The mounting frame 51 is provided with a through portion, and the limit rod 21 passes through the through portion and is connected to the limit connector 4.

[0030] The driver 31 is a magnetic driver, and the driving rod 32 is a magnetic driving rod. When the magnetic driver is powered on, it provides a magnetic driving force to the magnetic driving rod, so that the driving rod 32 can be quickly pushed out, thereby driving the microneedle assembly 1 to move in a fast straight line, realizing rapid needle removal, and reducing the pain when the needle body pierces the skin. The magnetic driver is also provided with a reset spring that returns the magnetic driving rod to its original position when the magnetic driving force disappears. After the microneedle treatment device is powered off, the magnetic force in the magnetic driver disappears, and the magnetic driving rod returns to its original position under the reset force of the reset spring, so that the microneedle assembly 1 is automatically reset when the power is off, thereby improving the product experience and safety of the microneedle treatment device.

[0031] like Figure 1 As shown, the microneedle assembly 1 includes a bracket 11 and a microneedle plate 12. The bracket 11 includes a base 111 and a connecting column 112. The microneedle plate 12 is provided with a microneedle array 121. The microneedle plate 12 is fixed on the base 111. The connecting column 112 is connected to the limit connector 4.

[0032] The beneficial effects of the utility model are as follows: the driving device is connected to the limiting device through a limiting connector, the linear displacement output by the limiting rod is the linear displacement of the limiting connector, and the linear displacement is the limiting stroke of the limiting connector. Since the limiting connector allows the driving rod to move linearly within the limiting stroke, the needle extraction depth of the microneedle assembly can be adjusted by adjusting the linear displacement output by the limiting device.

[0033] Furthermore, the driving device can make the driving rod move quickly, thereby driving the microneedle assembly to move quickly, thereby achieving rapid removal of the microneedle assembly, causing the treated subject to feel less pain and providing a better experience.

[0034] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
