Description

Technical Field

[0001] This invention relates to the field of acne treatment technology, specifically to a radiofrequency acne treatment device. Background Technology

[0002] Acne is a chronic inflammatory skin disease with a high incidence rate among adolescents, often appearing on the cheeks, jawline, and trunk, and can be quite disfiguring. Radiofrequency ablation (RFA) is a common treatment for acne, as it can destroy bacteria and sebum on acne lesions, promoting skin repair and regeneration. RFA also has relatively few side effects and a short recovery time. However, existing RF acne treatment devices still have some shortcomings and deficiencies that require improvement: For example, a radiofrequency acne treatment device with application number CN201510500452.0 includes a main unit and treatment handles connected to the main unit. The device includes at least two treatment handles connected to the main unit. The two treatment handles are an invasive treatment handle for selectively destroying sebaceous gland cells and killing Propionibacterium acnes at high temperatures, and a non-invasive treatment handle for heating sebum in the dermis. Two treatment handles are connected to the same main unit. One is an invasive treatment handle used for selectively destroying sebaceous gland cells and killing Propionibacterium acnes at high temperatures; the other is a non-invasive treatment handle used for heating sebum in the dermis to reduce pain during pus extraction and promote dermal collagen regeneration, preventing acne scarring after treatment. The current distribution control of the radiofrequency electrodes on the treatment handles effectively increases the heat diffusion area, resulting in more uniform energy distribution across the entire treatment surface, thus achieving shorter treatment time, better efficacy, and prevention of recurrence.

[0003] The radiofrequency acne treatment devices mentioned in the above documents mostly have their treatment handles placed directly outside without a dedicated place to protect them. When not in use, the treatment handles may fall off due to external impacts, causing damage to the handles.

[0004] For example, a radiofrequency acne treatment device with application number CN201310665135.5 includes a main unit, which is connected to a handle via a pipe. A sealing cover is installed at the front end of the handle, and a microneedle emitter and a suction bottle are installed inside the handle. The wire of the microneedle emitter passes through the pipe and is connected to the control circuit inside the main unit. A microneedle is installed at the front end of the microneedle emitter, and the tip of the microneedle is located in the central hole of the sealing cover and can extend forward. The radiofrequency negative electrode that cooperates with the microneedle is connected to the control circuit inside the main unit via a wire. An air conduit and a drainage tube are connected to the suction bottle. The inlet end of the air conduit and the outlet end of the drainage tube both extend into the suction bottle. The outlet end of the air conduit passes through the pipe and is connected to a vacuum negative pressure machine installed inside the main unit. The inlet end of the drainage tube is close to the tip of the microneedle. The main unit mainly includes a radiofrequency power supply, a control circuit, and a vacuum negative pressure machine. The main unit has an RF output power of 1-100W and an output frequency of 0.3MHz-100MHz, with the specific value determined according to actual needs, possibly 1MHz; the vacuum negative pressure unit provides 3psi of negative pressure.

[0005] The radiofrequency acne treatment device described in the aforementioned document does not allow for quick and convenient replacement of the treatment head. When users need to treat acne in different areas, the fixed-size treatment head may not meet the needs of medical personnel, thus presenting certain limitations.

The upper end of the movable groove is nested with an extrusion rod, and the upper end of the movable groove has sliding grooves on both sides, and the sliding grooves are nested with a sliding plate, which is fixedly connected to the extrusion rod.

[0010] Preferably, the fixed airbag is connected to the air supply airbag through a connecting pipe to form a through structure, and the slide plate is connected to the slide groove through a compression rod to form a sliding structure.

[0011] Preferably, the auxiliary fixing mechanism includes a rotating shaft, which is nested inside the storage slot, and a torsion spring is fixedly connected between the rotating shaft and the storage slot, and a rotating plate is fixedly connected to the rotating shaft.

The upper end of the placement box is nested with a limiting rod, and a pressing plate is fixedly connected to the top of the limiting rod, and a placement opening is provided on the pressing plate. A fixing rod is fixedly connected to the inner side of the upper end of the placement box, and a limit rod is nested at the outer end of the fixing rod. A return spring is fixedly connected to the bottom of the limit rod, and the lower end of the return spring is fixedly connected inside the placement box.

[0012] Preferably, the rotating shaft forms a traction structure via a traction rope, the rotating plate forms a rotation structure via the rotating shaft, and the outer end of the rotating plate is designed in an arc shape.

[0013] Preferably, the placement opening and the placement slot are horizontally aligned, the pressing plate and the limiting rod form an integrated structure, and the limiting rod and the placement box form an elastic structure through a return spring.

[0014] Preferably, the clamping mechanism includes a connecting plate, which is fixedly connected to the lower end of the auxiliary plate, and a working box is fixedly connected to the lower end of the connecting plate, and a connecting rod is fixedly connected inside the working box; A sliding sleeve is nested on the connecting rod, and a compression spring is fixedly connected to the inner side of the sliding sleeve. A sliding plate is fixedly connected to the upper side of the outer end of the sliding sleeve, and a clamping rod is fixedly connected to the inner side of the sliding plate. The treatment head has a clamping groove on its side, and a clamping rod is nested inside the clamping groove. The upper end of the treatment head is electrically connected to a connector, and the connector is electrically connected to the connecting rod.

[0015] Preferably, there are two sets of sliding sleeves symmetrically distributed about the center point of the connecting rod, and the sliding sleeves form a sliding structure with the connecting rod through a sliding plate, and the sliding sleeves form an elastic structure through a compression spring.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) When the user is not using the treatment handle, he can pull up the pressing plate and put the treatment handle into the placement slot inside the placement box through the placement port. At this time, the treatment handle is stored inside the placement box, which reduces the possibility of the treatment handle falling out accidentally to a certain extent. (2) After the treatment handle is placed, the user can release the pressing plate. Under the action of the reset spring, the pressing plate will press down on the squeezing rod, and the squeezing rod will squeeze the air supply bag. At this time, the gas inside the air supply bag will enter the fixed bag through the connecting tube, causing the fixed bag to expand and wrap around the treatment handle. At this time, the fixed bag can further protect the treatment handle and reduce the possibility of damage to the treatment handle. (3) During the downward movement of the squeezing rod, the traction rope will be pulled simultaneously. At this time, the traction rope will pull the rotating shaft to rotate and drive the rotating plate to rotate and unfold. When it connects with the placed treatment handle, it further improves the stability of the treatment handle when it is placed and reduces the possibility of the upper end of the treatment handle shaking. (4) The user can connect the connector at the top of the treatment head to the connecting rod. At this time, there is a wireless connection between the connecting rod and the connector, so that the treatment head and the treatment handle can be assembled and subsequent treatment work can be carried out. (5) When the user needs to replace multiple treatment heads, the sliding plate can be pushed outward so that the treatment head and treatment handle can be assembled. When the sliding plate is released, the sliding sleeve will move inward and reset under the elastic force of the compression spring, so that the clamping rod enters the clamping groove on the side of the treatment head and clamps and fixes the treatment head. This can further improve the stability of the treatment head docking. Attached Figure Description

[0020] 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.

[0021] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown herein provides the following technical solution: a radiofrequency acne treatment device, which discloses a wrapping mechanism to wrap the lower end of the treatment handle 4 to prevent damage to the treatment handle 4: The main unit 1 has a switch 2 fixedly connected to the bottom front side, and a connecting wire 3 electrically connected to the top of the main unit 1.

A connecting pipe 15 is connected through the side of the air supply bladder 12, and the other end of the connecting pipe 15 is connected through the fixed air bladder 11. A compression rod 9 is nested at the upper end of the movable groove 14, and sliding grooves 21 are opened on both sides of the upper end of the movable groove 14. A sliding plate 22 is nested inside the sliding groove 21, and the sliding plate 22 is fixedly connected to the compression rod 9. The fixed air bladder 11 and the air supply bladder 12 form a through structure through the connecting pipe 15, and the sliding plate 22 forms a sliding structure with the compression rod 9 and the sliding groove 21.

[0022] When the user is not using the treatment handle 4, they can pull up the press plate 7 and put the treatment handle 4 into the placement slot 10 inside the placement box 6 through the placement port 8. At this time, the treatment handle 4 is stored inside the placement box 6, which reduces the possibility of the treatment handle 4 falling out accidentally to a certain extent. After the treatment handle 4 is placed, the user can release the pressure plate 7. At this time, the limiting rod 13 fixedly connected to the lower end of the pressure plate 7 will move downward along the fixed rod 23 under the action of the return spring 24. At this time, the pressure plate 7 will press down on the squeezing rod 9. The squeezing rod 9 moves in a limited position inside the slide groove 21 through the slide plate 22 and squeezes the air supply bag 12. At this time, the gas inside the air supply bag 12 will enter the fixed bag 11 through the connecting tube 15, causing the fixed bag 11 to expand and wrap around the treatment handle 4. At this time, the fixed bag 11 can further protect the treatment handle 4 and reduce the possibility of damage to the treatment handle 4.

[0023] Example 2: like Figure 2 , Figure 3 , Figure 4 and Figure 11 The technical solution shown herein provides the following technical solution: a radiofrequency acne treatment device, which discloses an auxiliary fixing mechanism. This auxiliary fixing mechanism rotates under the drive of the squeezing rod 9 and clamps the treatment handle 4 to prevent it from shaking. The extrusion rod 9 is nested inside the placement box 6, and storage slots 17 are provided on the left and right sides of the extrusion rod 9. An auxiliary fixing mechanism is provided between the storage slots 17 and the placement box 6. The auxiliary fixing mechanism includes a rotating shaft 20, which is nested inside the storage groove 17. A torsion spring 19 is fixedly connected between the rotating shaft 20 and the storage groove 17, and a rotating plate 18 is fixedly connected to the rotating shaft 20. A traction rope 16 is fixedly connected to the rotating shaft 20, and the traction rope 16 passes through the inside of the pressing rod 9. The bottom end of the traction rope 16 is fixedly connected to the upper end of the sliding groove 21. A limiting rod 13 is nested at the upper end of the placement box 6, and a pressing plate 7 is fixedly connected to the top of the limiting rod 13. A placement opening 8 is provided on the pressing plate 7. A fixing rod 23 is fixedly connected to the inner side of the upper end of the placement box 6, and a limiting rod 13 is nested at the outer end of the fixing rod 23. A return spring 24 is fixedly connected to the bottom of the limiting rod 13, and the lower end of the return spring 24 is fixedly connected inside the placement box 6. The rotating shaft 20 forms a traction structure through the traction rope 16, and the rotating plate 18 forms a rotation structure through the rotating shaft 20. The outer end of the rotating plate 18 is designed with an arc shape. The placement port 8 and the placement groove 10 are horizontally corresponding. The pressing plate 7 and the limiting rod 13 form an integrated structure. The limiting rod 13 forms an elastic structure with the placement box 6 through the return spring 24.

[0024] As the compression rod 9 moves downward, it simultaneously pulls the traction rope 16. At this time, the traction rope 16 pulls the rotating shaft 20 to rotate. As the rotating shaft 20 rotates, it simultaneously drives the rotating plate 18 to rotate and unfold. At this time, the outer end of the rotating plate 18 can connect with the placed treatment handle 4, which further improves the stability of the treatment handle 4 when it is placed and reduces the possibility of the upper end of the treatment handle 4 shaking.

[0025] Example 3: like Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The technical solution shown herein provides the following technical solution: a radiofrequency acne treatment device, which discloses a clamping mechanism, and the clamping mechanism is internally provided with a treatment head 5, through which different models of treatment heads 5 can be replaced: The docking rod 25 is electrically connected to the inside of the treatment handle 4, and the auxiliary plate 26 is fixedly connected to the inside of the treatment handle 4. The docking rod 25 is connected through the auxiliary plate 26, and a clamping mechanism is provided at the lower end of the auxiliary plate 26. The clamping mechanism includes a connecting plate 30, which is fixedly connected to the lower end of the auxiliary plate 26. A working box 31 is fixedly connected to the lower end of the connecting plate 30, and a connecting rod 35 is fixedly connected inside the working box 31. A sliding sleeve 32 is nested on the connecting rod 35, and a compression spring 34 is fixedly connected to the inner side of the sliding sleeve 32.

Two sets of sliding sleeves 32 are symmetrically distributed about the center point of the connecting rod 35. The sliding sleeves 32 and the connecting rod 35 form a sliding structure through the sliding plate 33. The sliding sleeves 32 also form an elastic structure through the compression spring 34. The clamping rod 28 has an arc-shaped elastic design and forms an integrated structure with the sliding plate 33.

[0026] The user can connect the connector 29 at the upper end of the treatment head 5 to the connecting rod 25. At this time, there is a wireless connection between the connecting rod 25 and the connector 29, allowing the treatment head 5 to be assembled with the treatment handle 4 for subsequent treatment. When the user needs to replace multiple treatment heads 5, the sliding plate 33 can be pushed outward to assemble the treatment head 5 with the treatment handle 4. When the sliding plate 33 is released, the sliding sleeve 32 will move inward and reset under the elastic force of the compression spring 34. The sliding sleeve 32 simultaneously drives the sliding plate 33 to move. At this time, the sliding plate 33 drives the clamping rod 28 to move inward, so that the clamping rod 28 enters the clamping groove 27 on the side end of the treatment head 5 to clamp and fix the treatment head 5. This can further improve the stability of the treatment head 5 during docking.
