Description

Technical Field

[0001] The present invention relates to medical cosmetic equipment, in particular to a skin roller for removing scars. Background Art

[0002] Healthy skin tissue typically has irregularly arranged fiber bundles. Scars, however, occur when the body naturally repairs damaged skin tissue. This occurs when a large number of these repaired fiber bundles become arranged in parallel and orderly within the dermis, creating a concave or convex appearance at the wound site, affecting the patient's skin appearance. Therefore, in scar tissue treatment, blocking these orderly arranged fibers to create the same interlaced pattern seen in healthy skin is an effective and feasible approach. Summary of the Invention

[0003] The purpose of the present invention is to provide a scar removal skin roller that can effectively cut the hyperplastic fibrous tissue of the skin, thereby assisting in scar removal.

[0004] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is: a scar removal skin roller needle, including a handle and a roller needle cylinder arranged at the front end of the handle and rotating with the handle; a plurality of puncture needles for cutting fibrous tissue are evenly distributed on the circumference of the roller needle cylinder, and the puncture needles are in the shape of triangular thorns.

[0005] Preferably, a mounting fork is provided at the front end of the handle, a mounting hole is provided on the mounting fork, and the needle roller is connected to the handle through the mounting hole to form a rotational fit.

[0006] Preferably, the needle roller includes a cylinder body, with rotating shafts provided at both ends of the cylinder body, the rotating shafts passing through the mounting holes on the mounting fork, a plurality of mounting holes extending radially along the cylinder body are provided on the circumference of the cylinder body, and the puncture needle is provided in the mounting holes.

[0007] Preferably, the needle roller includes a central axis, end plates arranged near both ends of the central axis, and a plurality of needle plates sleeved on the central axis between the end plates; the two ends of the central axis are inserted into the mounting holes on the mounting fork; the needle plate includes a plate body, and a central sleeve arranged at the center of the plate body and cooperating with the central axis; the puncture needles are evenly arranged on the edge of the plate body and extend radially along the plate body.

[0008] Preferably, the needle surface of each side of the puncture needle is in a concave arc shape.

[0009] Preferably, a number of convex teeth are evenly arranged in a ring shape on the end surfaces of both ends of the center sleeve, and a movable interval is formed between the convex teeth, and the size of the convex teeth is smaller than the movable interval; in two adjacent needle disks, the convex teeth on the center sleeve of one needle disk are correspondingly clamped in the movable interval of the other; the needle disk is divided into a fixed disk and a movable disk, and the movable disk and the fixed disk are staggered with each other.

[0010] Preferably, the center sleeve of the fixed disk is bonded to the center shaft.

[0011] Preferably, the distance between two adjacent puncture needles is less than 2 mm.

[0012] Preferably, the needle roller cylinder is adapted to be equipped with a shell that can be inserted onto the outside of the needle roller cylinder.

[0013] The beneficial effects of the present invention are mainly reflected in: it can effectively cut and loosen the fibrous tissue at the scar skin, disrupt the orderly arrangement of the fibrous tissue formed in the natural healing process, can effectively improve the internal tissue structure of the scar, and achieve a cosmetic effect on the skin. Specifically, during use, the scar to be repaired and the roller needle are first disinfected, and the operating physician holds the handle, aims the roller needle cylinder at the affected skin, and gradually rolls it. As the puncture needle penetrates the scar tissue, it can cut and loosen the fibrous tissue at the scar. The puncture needle of the present invention adopts the special shape of a triangular thorn, which can greatly improve the cutting and loosening effect compared with the traditional needle type, and improves the removal effect of scar tissue. At the same time, during the roller needle puncture process, the present invention can cause internal bleeding in the scar tissue, and a large number of platelets gather inside the scar and in the scar epidermal tissue. The activated platelets release related cytokines to start the regeneration and repair process of the skin tissue, and promote the regeneration and repair of the scar tissue to normal tissue more quickly. And because tens of thousands of tiny channels are formed on the surface of scar tissue, it is conducive to drug penetration. After puncture, scar-inhibiting drugs are applied to the scar surface, which is conducive to drug penetration and further accelerates scar repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] like Figure 1-4As shown, a scar removal skin roller is used to cut and loosen scar tissue (including hypertrophic scars and atrophic scars) to promote the skin to restore the shape of healthy skin, improve the skin appearance, and have the function of scar removal and beauty. Figure 1 As shown in the figure, the present invention includes a handle 1 and a needle roller 2 provided at the front end of the handle 1 and in rotation with the handle 1. A number of puncture needles 3 (hundreds or even thousands, for the sake of clarity, are only schematically shown in each figure) for cutting fibrous tissue are evenly distributed on the circumference of the needle roller 2. When in use, the present invention is rolled along the scar, and the puncture needles 3 are used to cut and loosen the scar fibrous tissue, calmly disrupting its originally orderly arrangement structure and restoring it to the messy state of normal skin tissue, ultimately achieving the effect of removing scars. The puncture needle used in the present invention is different from the traditional circular reduction needle. It uses the following method: Figure 2 The triangular thorn shape shown in the figure makes its edge sharp, which improves the cutting and loosening effect on the tissue. Of course, a better approach can be that the needle surface of each side of the puncture needle 3 can be set to be a concave arc, thereby further improving the sharpness of the edge position.

[0019] During the installation process, the present invention can be Figure 1 As shown in FIG, a mounting fork 4 is provided at the front end of the handle 1, and a mounting hole 5 is provided in the mounting fork 4. The needle roller 2 is connected to the handle 1 through the mounting hole 5 to form a rotational connection. Of course, it is also possible to provide a protruding pin on the mounting fork 4, and then provide recessed portions at both ends of the needle roller 2 corresponding to the pin to achieve the rotational connection. Alternatively, a structure that achieves the same function is feasible, but is not illustrated in this invention.

[0020] There are many specific forms of the needle roller cylinder 2. It can be a cylinder with a complete cylinder surface, or a frame cylinder formed by a combination of a bracket disc, etc., as described below, for example:

[0021] 1. The needle roller 2 may include a cylinder, with rotating shafts provided at both ends of the cylinder, the rotating shafts being passed through the mounting holes 5 on the mounting fork 4, and a plurality of mounting holes 5 extending radially along the cylinder being provided on the circumference of the cylinder, the puncture needle 3 being provided in the mounting holes 5.

[0022] 2. The needle roller 2 includes a central shaft 6, end plates 7 positioned near each end of the central shaft 6, and a plurality of needle plates 8 sleeved onto the central shaft 6 between the end plates 7. The ends of the central shaft 6 are inserted into mounting holes 5 on the mounting fork 4. The needle plate 8 includes a plate body 9 and a center sleeve 10 positioned at the center of the plate body 9 and mating with the central shaft 6. The puncture needles 3 are evenly distributed along the edges of the plate body 9 and extend radially along the plate body 9.

[0023] During use, the present invention first disinfects the scar to be repaired and the roller needle, and after applying local anesthesia or surface anesthesia, the operating physician holds the handle 1, aims the roller needle cylinder 2 at the affected skin, and gradually rolls it in a rice-shaped rolling manner to evenly punch holes on the surface of the scar. As the puncture needle 3 penetrates the scar tissue, it can cut and loosen the fibrous tissue at the scar. Due to the special shape of the puncture needle 3 of the present invention, it can greatly improve the cutting and loosening effect compared with the traditional needle type, thereby improving the removal effect of scar tissue. At the same time, during the roller needle puncture process, the present invention can cause internal bleeding in the scar tissue, and a large number of platelets will aggregate inside the scar and in the scar epidermis. The activated platelets release related cytokines, which can initiate the regeneration and repair process of the skin tissue and promote the regeneration and repair of the scar tissue to normal tissue more quickly. In addition, since tens of thousands of tiny channels are formed on the surface of the scar tissue, it is conducive to drug penetration. After puncture, scar-inhibiting drugs are applied to the surface of the scar to facilitate drug penetration and further accelerate scar repair.

[0024] Since the positions of adjacent puncture points (cutting and loosening points) during the rolling process of the present invention's needle rollers are primarily determined by the positions of the puncture needles, which are typically fixed to the disc. This means that the positions of all puncture needles are fixed after shipment. To further improve the irregularity of the cutting and loosening process, one approach could be to enable all or some of the puncture needles to be repositioned relative to the entire needle roller 2. For example, two adjacent needle discs could be rotated relative to each other, rather than rolling synchronously, thereby further enhancing the cutting and loosening effect.

[0025] In order to achieve the above purpose, a feasible structure may be that a plurality of protruding teeth 11 are evenly arranged in a ring shape on the end surfaces of both ends of the center sleeve 10, and a movable interval 12 is formed between the protruding teeth 11, and the size of the protruding teeth 11 is smaller than the movable interval 12. In two adjacent needle disks 8, the protruding teeth 11 on the center sleeve 10 of one needle disk 8 are correspondingly clamped in the movable interval 12 of the other needle disk, providing space for movement. The needle disk 8 is divided into a fixed disk and a movable disk, and the movable disk and the fixed disk are interlaced with each other. Generally, the center sleeve 10 of the fixed disk is bonded to the central shaft 6 to form a fixed connection with the central shaft 6.

[0026] Through such a design, during the rolling process of the present invention, the fixed disk can rotate relatively stably along with the rolling, and the movable disk can rotate relative to the central axis and has a convex tooth 11 with movement space in the movable range 12, so it can follow the rotation in an incompletely synchronous manner, thereby improving the randomness of the cutting and loosening points.

[0027] In addition, to protect the puncture needles and the user, the roller needle cylinder 2 is fitted with a housing that fits snugly over the roller needle cylinder 2. The spacing between two adjacent puncture needles 3 can be customized as needed, but is generally less than 2 mm. Only with a sufficiently high puncture needle density can tens of thousands of holes be punched into the scar surface at once, achieving a successful scar release effect. Multiple rolling movements can effectively loosen the scar, while avoiding the problems of poor pain tolerance and high rolling resistance caused by overly dense punctures. The length of the puncture needles 3 in the present invention can be designed based on the thickness of the scar, with models offering different needle lengths, such as 0.5 mm, 1.0 mm, 1.5 mm, and 2.0 mm.
