Description

Technical Field

[0001] The utility model relates to the technical field of microneedle medical treatment, in particular to a skin flattening device and a handle. Background Art

[0002] Radiofrequency microneedle is a minimally invasive radiofrequency dot matrix technology. It uses fine microneedles to precisely apply radiofrequency energy to target tissues at different depths, fundamentally changing the problems of traditional laser and radiofrequency treatments such as uncertain treatment depth, difficult control of skin damage, and serious attenuation of energy transmission. At the same time, it avoids side effects such as pigmentation. It can be used for beauty treatments such as skin tightening and scar removal, and can also be used to treat acne and axillary hyperhidrosis.

[0003] Since the skin of different parts of the human body is uneven and the tightness varies from person to person, the microneedle treatment head is designed as a flat surface. When performing microneedle treatment on parts with many folds, the depths of the needle bodies inserted into the skin are different, resulting in skin damage and affecting the treatment effect on the skin.

[0004] Currently, a negative pressure microneedle treatment head is usually used to adsorb the skin to stretch and flatten it so that the needle bodies can be evenly inserted into the flattened skin. However, when the negative pressure microneedle treatment head adsorbs the skin, the skin will be bruised or swollen due to being sunken in the annular groove, resulting in skin damage and affecting the treatment effect on the skin. Summary of the Utility Model

[0005] The main purpose of the utility model is to propose a skin flattening device and a handle, aiming to reduce the possibility of skin damage during flattening.

[0033] In the related art, a radio frequency microneedle is a minimally invasive radio frequency dot matrix technology. It uses fine microneedles to precisely apply radio frequency energy to target tissues at different depths. Since the skin of different parts of the human body is uneven and the tightness varies from person to person, and the treatment head of the radio frequency microneedle treatment is of a flat design, when performing microneedle treatment on parts with many wrinkles, the depths of the needle bodies inserted into the skin are inconsistent, resulting in skin damage and affecting the treatment effect on the skin. Usually, a negative pressure microneedle treatment head is used to adsorb the skin so that the needle bodies can be evenly inserted into the flattened skin. However, when the negative pressure microneedle treatment head adsorbs the skin, the skin will be bruised or swollen due to being sunken in the annular groove, resulting in skin damage and affecting the treatment effect on the skin.

[0034] Based on the above problems and concepts, as Figures 1 to 4As shown in the figure, the present utility model provides a skin flattening device 100 for flattening the skin. The skin flattening device 100 includes a housing 1 and a flattening member 2. The housing 1 encloses a through hole 11 for the micro needle treatment head 4 to pass through; one end of the flattening member 2 is connected to the housing 1, and the other end extends in a direction away from the housing 1 and forms a flattening end 24. The flattening end 24 is used to abut against the skin; wherein, pressing or releasing the housing 1 drives the flattening member 2 to deform or reset, so that when the through hole 11 approaches or moves away from the skin, the flattening end 24 unfolds or relaxes the skin.

[0035] In this embodiment, the skin flattening device 100 is composed of a housing 1 and a flattening member. The housing 1 encloses a through hole 11, and the flattening member 2 is connected to the housing 1. Before treatment with the micro needle treatment head 4, the micro needle treatment head 4 is passed through the through hole 11 of the housing 1 so that the housing 1 is sleeved on the micro needle treatment head 4. At least a part of the micro needle treatment head 4 extends out of the through hole 11, but does not exceed the flattening end 24 of the flattening member 2. Then, the micro needle treatment head 4 is pressed perpendicular to the treatment surface of the skin. The housing 1 moves with the micro needle treatment head 4 and approaches the treatment surface, or the housing 1 is also pressed and approaches the treatment surface. When the flattening end 24 of the flattening member 2 contacts the skin, the flattening member 2 is deformed under the pressure of the housing 1 and the skin at the same time. The flattening end 24 of the flattening member 2 moves away from the through hole 11 to drive the skin on the treatment surface to unfold and tighten through friction. As the flattening end 24 gradually moves away, the distance between the through hole 11 of the housing 1 and the treatment surface becomes shorter until the micro needle treatment head 4 inserted into the through hole 11 abuts against the treatment surface, and the micro needle is inserted into the treatment surface for treatment. In this way, the skin can be unfolded, the flatness of the treatment surface can be improved, the depth of the micro needle inserted into the treatment surface is uniform, damage to the skin can be avoided, the treatment effect on the skin can be improved, and at the same time, damage such as bruising or swelling of the skin during flattening can be avoided. When the micro needle treatment head 4 and the housing 1 leave the skin, the flattening member 2 returns to its original position for the next flattening.

[0036] In actual implementation, one, two, three, four, five, etc. of the flattening members 2 can be provided. The flattening members 2 can be arranged along the circumference of the through hole 11, and the number of the flattening members 2 provided is not specifically limited herein. Optionally, the flattening members 2 are arranged oppositely so that when the flattening members 2 abut against the skin, the flattening ends 24 of the flattening members 2 are relatively far away from each other, improving the flattening efficiency and effect on the treatment surface.

[0037] Optionally, the micro needle treatment head 4 can be passed through the through hole 11 of the housing 1 by interference fit, or the housing 1 is detachably connected to the micro needle treatment head 4 by means of cooperation of bolts or screws and screw holes, snap-fit structures or plug-in structures, etc. The housing 1 can be integrally formed or divided. Optionally, when the housing 1 is divided, each part of the housing 1 can be provided with a flattening member 2, and each part of the housing 1 can be respectively connected to different sides of the micro needle treatment head 4, which is not specifically limited herein.

[0038] In an embodiment of the present utility model, as Figure 1 shown, the flattening member 2 is a first plate member 21, and the first plate member 21 is detachably connected to the housing 1. One end of the first plate member 21 away from the housing 1 is bent towards the side facing away from the through hole 11 to form a flattening end 24.

[0039] In this embodiment, the first plate member 21 is made of a material with certain elasticity. One end of the first plate member 21 away from the housing 1 is bent to form a flattening end 24. When the flattening end 24 is subjected to the pressure of the treatment surface, the first plate member 21 deforms, and the flattening end 24 will move towards the side facing away from the through hole 11 to flatten the treatment surface and improve the treatment effect of the microneedles. The first plate member 21 is detachably connected to the housing 1 to facilitate the replacement of the damaged or aged first plate member 21 or housing 1.

[0040] It can be understood that one end of the first plate member 21 away from the housing 1 is bent towards the side facing away from the through hole 11. The outer arc surface of the bent part is used to abut against the treatment surface, further reducing the possibility of damage to the treatment surface when the flattening member 2 flattens the treatment surface and reducing the discomfort at the treatment surface. At the same time, the first plate member 21 is bent, reducing the resistance when the first plate member 21 moves on the treatment surface, facilitating the deformation of the first plate member 21. When the flattening end 24 of the first plate member 21 leaves the treatment surface, the first plate member 21 returns to its original position for the next flattening. In actual implementation, the first plate member 21 can be hook-shaped or U-shaped. The first plate member 21 can be made of a material with certain elasticity such as plastic or elastic sheet. The housing 1 and the first plate member 21 are detachably connected by the cooperation of screws and screw holes, which are not specifically limited herein.

[0041] In an embodiment of the present utility model, as Figure 1 shown, the housing 1 is made of soft rubber material and is arranged in a ring shape or an open ring shape. The housing 1 surrounds to form a through hole 11.

[0042] In this embodiment, the housing 1 can be connected to the microneedle treatment head 4 by interference fit. The housing 1 is made of soft rubber material, enabling the housing 1 to have a certain elastic deformation ability, facilitating the sleeving of the housing 1 on the microneedle treatment head 4. The housing 1 is arranged in a ring shape, and the inner wall of the housing 1 is the side wall of the through hole 11. The outer wall of the housing 1 is the connection surface of the first plate member 21. The housing 1 and the first plate member 21 are detachably connected by the cooperation of screws and screw holes. The connection surface of the first plate member 21 and the housing 1 is a plane to ensure the stability of the connection between the first plate member 21 and the housing 1. Alternatively, the housing 1 can also be an open ring shape, and the open ring shape surrounds to form a through hole with an opening. Due to the material characteristics of the soft rubber material, it can be wrapped around the outside of the microneedle treatment head 4 and fixed around the microneedle treatment head 4.

[0043] In an embodiment of the present utility model, as Figures 2 to 4As shown, the flattening member 2 includes a second plate member 22 and an elastic member 23. The elastic member 23 is connected to the housing 1. One end of the second plate member 22 is connected to the elastic member 23 and is movably connected to the housing 1. The other end of the second plate member 22 forms a flattening end 24.

[0044] In this embodiment, one end of the second plate member 22 is movably connected to the housing 1, the other end of the second plate member 22 is the flattening end 24, and an elastic member 23 is further provided between the second plate member 22 and the housing 1. When the flattening end 24 of the second plate member 22 contacts the treatment surface, the second plate member 22 is squeezed by the treatment surface, the position of the second plate member 22 relative to the housing 1 changes, the elastic member 23 between the second plate member 22 and the housing 1 deforms, and the flattening end 24 of the second plate member 22 moves away from the through hole 11 to flatten the treatment surface. When the flattening end 24 of the second plate member 22 leaves the treatment surface, the elastic member 23 rebounds to drive the second plate member 22 to reset, and the flattening end 24 of the second plate member 22 moves closer to the through hole 11 for the next flattening.

[0045] In actual implementation, the second plate member 22 and the housing 1 can be rotatably connected or slidably connected so that the second plate member 22 is movably connected to the housing 1, thereby ensuring the stability of the movement trajectory of the second plate member 22. The second plate member 22 can be in a plate shape or be bent. When the second plate member 22 is in a plate shape, a buffer pad can be provided at the flattening end 24 of the second plate member 22. When the second plate member 22 is bent, the bent surface is the contact surface of the flattening end 24 of the second plate member 22 to further reduce the possibility of damaging the treatment surface.

[0046] Optionally, depending on the different installation positions, when the flattening end 24 of the second plate member 22 moves to the side away from the through hole 11, the elastic member 23 can be in a compressed or extended state, which is not specifically limited here.

[0047] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, the housing 1 is provided with a mounting hole 121. The second plate member 22 is correspondingly provided with a rotating shaft 2221 for the mounting hole 121. The rotating shaft 2221 passes through the mounting hole 121. The elastic member 23 is installed on the housing 1 and is provided with a first abutting portion and a second abutting portion connected at an angle. The housing 1 abuts against the first abutting portion, and the second plate member 22 abuts against the second abutting portion.

[0048] In this embodiment, the second plate member 22 is rotatably connected through the cooperation of the rotating shaft 2221 and the mounting hole 121. The elastic member 23 is installed on the housing 1 and is provided with a first abutting portion and a second abutting portion. The first abutting portion is used to abut against the housing 1, and the second abutting portion is used to abut against the second plate member 22. When the flattened end 24 of the second plate member 22 is subjected to the pressure of the treatment surface and moves away from the through hole 11, the second plate member 22 presses against the second abutting portion, the second abutting portion approaches the first abutting portion, and the first abutting portion presses against the housing 1, causing the elastic member 23 to be compressed. When the second plate member 22 leaves the treatment surface, the second abutting portion rebounds to its original position to drive the second plate member 22 to reset.

[0049] It can be understood that the second abutting portion abuts against a part of the second plate member 22 on the side of the rotating shaft 2221 facing away from the flattened end 24. In this way, when the flattened end 24 moves away from the through hole 11, this part moves towards the housing 1, so that the elastic member 23 is in a compressed state.

[0050] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, an avoidance groove 12 is formed by enclosing the outer wall of the housing 1. The mounting hole 121 is provided on the groove wall of the avoidance groove 12. The elastic member 23 is provided in the avoidance groove 12, and the first abutting portion abuts against the groove wall of the avoidance groove 12.

[0051] In this embodiment, the outer wall of the housing 1 is recessed to form the avoidance groove 12. The groove wall of the avoidance groove 12 is provided with a mounting hole 121 that cooperates with the rotating shaft 2221 of the second plate member 22. In this way, the connection part of the second plate member 22 and the housing 1 is located in the avoidance groove 12, and the elastic member 23 is also provided in the avoidance groove 12 to reduce the volume of the skin flattening device 100 and facilitate the carrying, installation, and use of the skin flattening device 100.

[0052] In actual implementation, the avoidance groove 12 at least has a first groove wall, a second groove wall, and a third groove wall that are sequentially connected. Among them, the first groove wall and the third groove wall are oppositely arranged. The mounting hole 121 is provided on both the first groove wall and the second groove wall. The second plate member 22 is provided with a rotating shaft 2221 corresponding to each mounting hole 121, so that the second plate member 22 is stably rotatably connected to the housing 1. The elastic member 23 can also be connected to the first groove wall and the second groove wall in this way. The second plate member 22 and the second groove wall are oppositely arranged. The first abutting portion of the elastic member 23 abuts against the second groove wall of the avoidance groove 12, and the second abutting portion of the elastic member 23 abuts against the second plate member 22. No specific limitation is made here.

[0053] In an embodiment of the present utility model, as Figure 2 and Figure 3As shown, the second plate member 22 includes a first section 221, a second section 222, and a limiting section 223 that are connected to each other. The first section 221, the second section 222, and the limiting section 223 extend radially. A flattening end 24 is provided at one end of the first section 221 away from the second section 222. A rotating shaft 2221 is provided on the second section 222 and is arranged in contact with the second abutting portion. The housing 1 is provided with a limiting protrusion 13, and the limiting protrusion 13 is located between the second section 222 and the limiting section 223.

[0054] In this embodiment, one ends of the first section 221, the second section 222, and the limiting section 223 of the flattening member 2 are connected to each other, and the other ends of the first section 221, the second section 222, and the limiting section 223 extend radially outward. A flattening end 24 is formed at one end of the first section 221 away from the connecting portion. A rotating shaft 2221 that cooperates with the mounting hole 121 is provided on the side surface of the second section 222. One surface of the second section 222 facing away from the limiting section 223 abuts against the second abutting portion of the elastic member 23. At the same time, the housing 1 is provided with a limiting protrusion 13, and the limiting protrusion 13 is provided between the second section 222 and the limiting section 223. When the second plate member 22 is in the initial state, one surface of the second section 222 facing away from the limiting section 223 abuts against the second abutting portion, and one surface of the second section 222 facing the limiting section 223 abuts against the limiting protrusion 13. When the flattening end 24 of the second plate member 22 flattens the treatment surface, the second end presses against the second abutting portion and moves away from the limiting protrusion 13. As the housing 1 continuously approaches the treatment surface, the limiting section 223 gradually moves towards the limiting protrusion 13 until it abuts against the limiting protrusion 13. At this time, the second plate member 22 moves to the extreme position, and the housing 1 can no longer approach the treatment surface. By the cooperation of the second section 222, the limiting section 223, and the limiting protrusion 13, the rotation range of the second plate member 22 is controlled, and further the movement range of the flattening end 24 of the second plate member 22 is controlled to prevent the flattening end 24 of the second plate member 22 from overstretching the skin and causing skin damage. At the same time, the position of the second plate member 22 in the initial state is relatively fixed, and the second plate member 22 can directly flatten the treatment surface without adjusting the position of the second plate member 22.

[0055] During actual implementation, the second section 222 can be arranged in an arc shape to facilitate inserting the second section 222 between the limiting protrusion 13 and the second abutting portion of the elastic member 23, reducing the installation difficulty of the second plate member 22. The elastic member 23 can be a compression spring, a torsion spring, a spring sheet, etc. One elastic member 23 can be provided for each second plate member 22, or multiple elastic members 23 can be provided for each second plate member 22, and no specific limitation is made here.

[0056] In an embodiment of the present utility model, as Figure 2 shown, the elastic member 23 is a spring sheet; and / or, the material of the elastic member 23 is beryllium copper or spring steel or stainless steel.

[0057] In this embodiment, the elastic member 23 is a shrapnel to facilitate the formation of the first abutting portion and the second abutting portion. The elastic member 23 can be made of metal materials such as beryllium copper, spring steel, or unequal steel to improve the service life of the elastic member 23. The deformation range of the elastic member 23 is between 1 mm and 5 mm. The housing 1 and the second plate member 22 can be made of plastic materials or metals, etc., and no specific limitation is made here.

[0058] In an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the through hole 11 is rectangularly arranged. There are two flattening members 2, and the two flattening members 2 are arranged on both sides of the through hole 11; and / or, the flattening member 2 is inclined away from the through hole 11.

[0059] In this embodiment, the through hole 11 is rectangularly arranged so that the housing 1 is suitable for a general microneedle treatment head 4. When there are two flattening members 2, the two flattening members 2 are arranged on both sides of the through hole 11. In this way, at least two flattening ends 24 are arranged opposite to each other. When flattening the treatment surface, the two flattening ends 24 move away from each other relatively, thereby improving the efficiency of flattening the treatment surface. In the initial state, the flattening member 2 is inclined away from the through hole 11. In this way, when the flattening end 24 of the flattening member 2 is pressed by the treatment surface, the flattening member 2 has a tendency to move outwards, reducing the difficulty of the flattening end 24 of the flattening member 2 moving to the side away from the through hole 11.

[0060] The skin flattening device 100 of the present application is not limited to being applied to the microneedle treatment head 4, and can also be applied to other invasive medical devices such as other radiofrequency microneedles, negative pressure microneedles, and energy-free microneedles (such as hydroneedles), and can also be applied to other non-invasive medical devices such as ultrasonic treatment devices and laser treatment devices; all medical devices that act on the skin and need to flatten the skin for treatment can apply the skin flattening device 100 of the present application. Correspondingly, any medical device having the skin flattening device 100 of the present application should fall within the protection scope of the present application.

[0061] The present utility model also relates to a handle, as Figures 2 to 4 shown, the handle includes the skin flattening device 100 described in any one of the above, and further includes a support rod 3. The support rod 3 is detachably connected to the housing 1 and is arranged at an angle with the housing 1.

[0062] In this embodiment, the support rod 3 is connected to the housing 1. By holding the support rod 3, the housing 1 can be controlled to approach or move away from the treatment surface. In this way, there is no need to connect and combine the microneedle treatment head 4 with the housing 1. When performing microneedle treatment, one hand controls the housing 1 to approach the treatment surface through the support rod 3 to flatten the treatment surface with the flattening plate, and the other hand inserts the microneedle treatment head 4 into the through hole 11 and inserts the microneedles into the treatment surface. In this way, the skin flattening device 100 can be applied to different models of microneedle treatment heads 4.

[0063] In actual implementation, the support rod 3 includes a connecting section 31 and a holding section 32 which are connected. One end of the connecting section 31 is connected to the housing 1, and the holding section 32 is connected to the other end of the connecting section 31.
