Description

Technical Field

[0001] This utility model relates to the field of microneedling devices, and in particular to a multifunctional gold radiofrequency microneedling device. Background Technology

[0002] The gold radiofrequency microneedling device is used for skin beauty. Its "gold microneedles" are designed and composed of "microneedle probes, radiofrequency energy, and fractional laser technology". After entering the deep layer of the skin, the "gold microneedles" insert the microneedles into the skin with instantaneous vibration, and release the radiofrequency energy from the tip of the "gold microneedles" in a very short time. The energy is directly and completely injected into the dermis, which promotes effective denaturation and reorganization of proteins and increases collagen production.

[0003] A search revealed that the Chinese patent "A Novel Gold Radiofrequency Microneedling Device" (authorization announcement number CN211156215U) includes a main unit, a base plate, and rollers. The main unit includes a circuit board, a radiofrequency generator, and a negative pressure pump. The gold radiofrequency microneedling device also includes a gun head. A touch screen is located on the top of the main unit and is electrically connected to the main unit. A hanger is located on one side of the main unit, and the other side of the main unit is electrically connected to the gun head via a wire. The end of the gun head is electrically connected to the microneedle. The negative pressure pump inside the main unit controls the length of the microneedle extension, thereby controlling the depth of the microneedle insertion into the dermis. However, this method has the following drawbacks in actual use: Pre-adjusting the microneedle exposure length before insertion causes the microneedle to come into contact with the user's skin, easily causing discomfort in the treatment area. Furthermore, in uneven areas, gaps may exist between the microneedle and the skin, making it difficult to control the insertion depth and resulting in poor microneedling device performance.

[0004] Therefore, a multifunctional gold radiofrequency microneedle device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional gold radiofrequency microneedling device to solve the above-mentioned problems, thereby improving the issues of discomfort in the treatment area and difficulty in controlling the depth of microneedle insertion.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a multifunctional gold radiofrequency microneedling device, comprising a main unit and a gun head installed on its outer side, wherein a microneedle with microneedles is installed inside the gun head; it also includes an adjustment component, which is disposed on the outer side of the gun head and is used to adjust the distance between the user's skin and the microneedle; wherein the adjustment component includes an annular box and an annular airbag, one side of the annular airbag extends into the interior of the annular box, the annular box is fixedly fitted onto the outer side of the gun head, and a set of protrusions is installed on one side of the annular airbag.

[0007] Preferably, the adjustment assembly further includes a fixed tube, a guide tube is installed between the fixed tube and the annular box, a piston plate is slidably connected inside the fixed tube, and an electric push rod fixedly connected to the piston plate is installed inside the fixed tube.

[0008] Preferably, a valve is installed on the outside of the conduit.

[0009] Preferably, a wire is installed between the gun head and the main unit, and a touch screen is installed on the main unit.

[0010] Preferably, the host includes a circuit board and a radio frequency generator, and the host is electrically connected to the touch screen.

[0011] Preferably, one end of the gun head is rotatably connected to a set of pressure plates, one side of the pressure plates is in contact with the outer side of the microneedle, and the pressure plates and the gun head are in frictional contact.

[0012] Preferably, a limiting ring is installed inside the gun head, a set of limiting rods is installed on the outside of the limiting ring, and a set of limiting grooves that mate with the limiting rods are opened on the outside of the microneedle.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up an annular airbag, an electric push rod drives the piston plate to operate, which introduces the gas in the fixed tube into the annular airbag. The annular airbag is placed between the gun head and the skin to control the insertion depth of the microneedle. When the annular airbag expands, the insertion depth of the microneedle decreases, and vice versa. This allows the staff to adjust the insertion depth according to different skin areas of the user. With the airbag fitting snugly against the skin, the insertion operation is more accurate and easier to control.

[0015] 2. By setting raised dots, the ring-shaped airbag makes soft contact with the patient's skin, reducing the discomfort caused by direct contact between the microneedle and the skin. At the same time, the raised dots provide a gentle massage to the area near the microneedle insertion, reducing discomfort in the treatment area. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-4 As shown, a multifunctional gold radiofrequency microneedling device includes a main unit 100 and a gun head 200 mounted on its outer side. The gun head 200 has a microneedle 300 with microneedles installed inside. It also includes an adjustment component 400, which is located on the outer side of the gun head 200 and is used to adjust the distance between the user's skin and the microneedle 300. The adjustment component 400 includes an annular box 410 and an annular airbag 420. One side of the annular airbag 420 extends into the interior of the annular box 410. The annular box 410 is fixedly fitted to the outer side of the gun head 200. A set of protrusions 421 are installed on one side of the annular airbag 420.

[0023] like Figure 2 and Figure 3 As shown, the adjustment assembly 400 also includes a fixed tube 430, a conduit 431 is installed between the fixed tube 430 and the annular box 410, a piston plate 432 is slidably connected inside the fixed tube 430, and an electric push rod 433 fixedly connected to the piston plate 432 is installed inside the fixed tube 430.

[0024] When inserting microneedles into a flat area, the user starts the main unit 100, then holds the nozzle 200 and activates the electric push rod 433. This drives the piston plate 432 to introduce the gas in the fixed tube 430 into the annular box 410 along the conduit 431. The gas then compresses the annular airbag 420 to inflate. When the inflation is complete, the insertion depth is the difference between the length of the microneedle and the inflated thickness of the annular airbag 420. The user can then perform the microneedle insertion. After insertion, the annular airbag 420 contacts the user's skin to minimize the contact between the microneedle and the skin. The head 300 makes direct contact with the skin, which may cause discomfort. At the same time, the raised dots 421 provide a gentle massage to the area near the microneedle insertion, reducing discomfort in the treatment area. When used on other areas, if the insertion depth needs to be reduced, the piston plate 432 can be operated to continue to replenish the gas in the annular airbag 420, causing it to expand. If the insertion depth needs to be increased, the piston plate 432 can be operated in reverse to draw back a suitable amount of gas from the annular airbag 420, causing it to shrink. The adjustment method is flexible.

[0025] When targeting uneven areas, traditional microneedle insertion methods often result in the microneedle tip 300 coming into contact with the patient's skin, leading to incomplete insertion. Increasing the exposed length of the microneedle requires user control of the insertion depth, which can easily result in over-insertion or under-insertion. However, in this application, when working on uneven areas, if the insertion depth of the microneedle can be easily judged visually, the piston plate 432 can be driven to move accordingly. The expansion size of the annular airbag 420 is adjusted accordingly, and then the microneedle insertion is performed directly. During the insertion process, the slight deformation capability of the annular airbag 420 allows it to fit relatively against the uneven area, making it easier for the user to apply pressure and resulting in a more stable insertion operation.

[0026] If the unevenness of the skin area makes it difficult to judge the insertion depth of the microneedle by visual inspection, the annular airbag 420 can be pre-inflated to a larger extent. At this time, the microneedle can be inserted to a smaller depth. Then, the microneedle is inserted. The annular airbag 420 is in contact with the skin, and the user holds the gun head 200 to apply pressure to the working area. Then, according to the required insertion depth, the piston plate 432 is slowly driven to move in the opposite direction to slowly extract the gas in the annular airbag 420, thereby increasing the insertion depth of the microneedle until it is inserted in place, and the operation is completed.

[0027] like Figure 2 and Figure 3 As shown, a valve 434 is installed on the outside of the conduit 431.

[0028] The valve 434 is used to control the opening and closing of the conduit 431. When it is open, it facilitates the introduction and extraction of gas. When it is closed, it helps to ensure the expansion stability of the annular airbag 420.

[0029] like Figure 1 As shown, a wire is installed between the gun head 200 and the main unit 100, and a touch screen is installed on the main unit 100.

[0030] The use of wires facilitates the connection between the microneedle 300 on the gun head 200 and the main unit 100.

[0031] like Figure 1 As shown, the host 100 includes a circuit board and a radio frequency generator, and the host 100 is electrically connected to the touch screen.

[0032] After the microneedle is inserted into the corresponding area, the radio frequency generator inside the host 100 can be operated by using a touch screen to release radio frequency energy.

[0033] like Figure 2 and Figure 4 As shown, a set of pressure plates 210 are rotatably connected to one end of the gun head 200. One side of the pressure plate 210 contacts the outer side of the microneedle 300. The pressure plate 210 and the gun head 200 are in frictional contact, which can ensure the limiting effect of the pressure plate 210 on the microneedle 300 and reduce the phenomenon of accidental movement of the pressure plate 210.

[0034] After the microneedle 300 is inserted into the nozzle 200 and in place, the operator can rotate one end of the pressure plate 210 onto the microneedle 300 to limit and fix the microneedle 300. When the microneedle 300 needs to be replaced later, the pressure plate 210 can be rotated to separate from the microneedle 300, and then the microneedle 300 can be poured out. It is easy to disassemble and assemble.

[0035] like Figure 3 and Figure 4 As shown, a limiting ring 220 is installed inside the gun head 200, and a set of limiting rods 221 are installed on the outside of the limiting ring 220. A set of limiting grooves that mate with the limiting rods 221 are opened on the outside of the micro needle head 300.

[0036] A limiting ring 220 is used to limit the depth of the microneedle 300 inserted into the gun head 200. The limiting rod 221 is connected to the limiting groove to prevent the microneedle 300 from rotating accidentally after being inserted.

[0037] Working Principle: When inserting microneedles into a flat area, the user starts the main unit 100, then holds the gun head 200 and activates the electric push rod 433, which drives the piston plate 432 to introduce the gas in the fixed tube 430 into the annular box 410 along the guide tube 431. The gas then compresses the annular airbag 420 to expand. Once fully expanded, the insertion depth is the difference between the length of the microneedle and the expanded thickness of the annular airbag 420. The user can then perform the microneedle insertion. After insertion, the annular airbag 420 contacts the user's skin, reducing discomfort caused by direct contact between the microneedle tip 300 and the skin. Simultaneously, the raised dots 421 provide a gentle massage to the area around the microneedle insertion site, reducing discomfort in the treatment area. When using the device on other areas, if a shallower insertion depth is needed, the annular airbag 420 can be replenished with gas to expand it. If a deeper insertion depth is needed, the gas in the annular airbag 420 can be appropriately withdrawn. The adjustment method is flexible; when targeting uneven areas, if the insertion depth of the microneedle can be easily judged by the naked eye, the piston plate 432 can be driven to move accordingly, and the expansion size of the annular airbag 420 can be adjusted accordingly. Then, the microneedle insertion operation can be performed directly. During the insertion process, the slight deformation ability of the annular airbag 420 itself can fit relatively close to the uneven area, making it easier for the user to apply pressure and making the insertion operation more stable. If the unevenness of the skin area is more special, making it difficult to judge the insertion depth of the microneedle by the naked eye, the annular airbag 420 can be pre-inflated to a larger size. At this time, the microneedle can be inserted to a smaller depth. Then, the microneedle insertion operation is performed. The annular airbag 420 is in contact with the skin, the user holds the gun head 200 to apply pressure to the working area, and then, according to the required insertion depth, the piston plate 432 is slowly driven to move in the opposite direction to slowly extract the gas in the annular airbag 420, so that the microneedle insertion depth is increased until it is inserted into place and the operation is completed.

[0038] After the microneedle 300 is inserted into the gun head 200 and in place, the operator can rotate one end of the pressure plate 210 onto the microneedle 300 to limit and fix the microneedle 300. When the microneedle 300 needs to be replaced later, the pressure plate 210 can be rotated to separate from the microneedle 300, and then the microneedle 300 can be poured out. It is easy to disassemble and assemble.

[0039] The entire device allows for adjustment of the insertion depth and placement method of the microneedles according to usage requirements, meeting the needs of different areas for placement depth and facilitating user operation. The use of the annular airbag 420 and the raised points 421 reduces discomfort during operation, and the microneedle tip 300 is easy to disassemble and assemble, allowing staff to quickly complete replacements. Overall, the device is versatile and highly practical.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
