Description

Technical Field

[0001] The present invention relates to the technical field of medical aesthetics, and particularly to a medical aesthetic scar removal device. Background Art

[0002] A scar is a fibrotic tissue formed during the wound repair process of the skin, and its formation is closely related to the excessive deposition and disordered arrangement of collagen fibers. The appearance, texture, and symptoms (such as itching and pain) of scars vary due to individual differences, types of trauma, and the repair process. Traditional scar removal methods include surgical resection, drug application, and pressure therapy, etc.

[0003] For the drug application method, manual application is mostly used, but it is difficult to ensure uniform application during the application process. Regarding this problem, in the prior art, the scar removal device for medical aesthetics with the publication number CN215135776U discloses a scar removal device for medical aesthetics department, including a base. One side of the upper end surface of the base is provided with a storage cavity, and a vertical control panel is fixed on one side of the upper end surface of the base. The control panel is located on one side of the storage cavity. The scar removal device for medical aesthetics department replaces the traditional manual medicine application method. By evenly wetting the medical sponge on the medicine application roller and controlling the reciprocating movement of the medicine application roller by a sliding screw rod, it avoids human hand contact. On the premise of ensuring uniform application, it effectively improves medical hygiene; and by controlling the movement of the piston rod, it is convenient to control the single dose of medicine; by movably installing a lifting plate on the base, it is convenient to lift the patient's arm; in addition, the distance between the two lifting plates can be adjusted by a bidirectional screw rod, and the distance between the patient's arm and the medicine application roller can be adjusted by an electric lifting rod, so as to be applicable to different patients for treatment.

[0004] During the actual use process, although the above device can adjust the distance between the patient's arm and the medicine application roller through a telescopic rod, for the same user, the diameters of different positions of the arm are different, and the movement trajectory of the medicine application roller of the above device is always on the same horizontal plane, making it difficult to fit the human curve, resulting in the situation of excessive squeezing and damaging the skin or incomplete application.

[0005] Therefore, the present invention proposes a medical aesthetic scar removal device to solve the above problems. Summary of the Invention

[0006] To solve the above problems, the present invention provides a medical aesthetic scar removal device, which changes the movement trajectory of the medicine application mechanism to conform to the curve of the arm, thereby reducing the possibility of excessive squeezing and damaging the skin or incomplete application during medicine application.

[0007] To achieve the above object, the technical solution of the present invention is as follows: A medical aesthetic scar removal device includes a base and a support frame. The support frame is installed at the top of the base. A placement component for placing the arm to be treated is installed at the top of the base. A transmission component is installed inside the support frame. A rolling component for applying medicine to the arm to be treated is installed at the lower end of the transmission component. A driving component for providing driving force for the transmission component is provided inside the support frame. The transmission component is used to make the movement track of the rolling component a streamline curve;

[0008] The transmission component includes a driving shaft fixedly connected to the driving component. One end of the driving shaft away from the driving component is located inside the support frame and is coaxially fixedly connected with a guiding rotating body. A spiral guide rail with a gradually changing pitch is fixedly connected to the surface of the guiding rotating body along its central axis direction. A guiding wheel is slidably engaged with the spiral guide rail. The guiding wheel is rotatably connected to a lifting rod. The bottom end of the lifting rod is fixedly connected to the rolling component. A sliding block slidably engaged with the lifting rod is sleeved around the middle of the lifting rod. One side of the sliding block is horizontally fixedly connected with a moving rod slidably engaged with the support frame; The guiding rotating body is a cylinder and the cylindrical surface is a streamline curved surface.

[0009] Principle of the basic solution: First, through the design of the lifting rod, the moving rod and the sliding sleeve, the rolling component is limited to move in a specific plane (vertical plane). Then, due to the gradually changing pitch design and the guiding rotating body being a cylinder with a streamline curved surface, when the driving shaft rotates, the guiding wheel moves along the spiral guide rail, causing the lifting rod to move in the vertical direction and the moving rod to move in the horizontal direction. Then, through the sliding block, the movements of the three (lifting rod, sliding block and moving rod) are synthesized, so that the rolling component fixed at the bottom end of the lifting rod makes a specific planar curve movement in this specific plane, that is, a movement track conforming to the curve of the human arm, so as to reduce the situation of excessive squeezing and damaging the skin or incomplete application during drug application.

[0010] Adopting the above solution has the following beneficial effects: Compared with the prior art, in this solution, through the synergistic effect of the gradually changing pitch design of the spiral guide rail and the streamline guiding rotating body, the rolling component can perform multi-dimensional linkage along a composite curve track. This track dynamically simulates the physiological curvature characteristics of the human arm through the precise synthesis of horizontal displacement and vertical lifting. Compared with the traditional straight line, this solution effectively solves the problem of local pressure imbalance caused by the mismatch between the mechanical movement path and the skin surface. In the vertical direction, the gradually changing pitch adjusts the gradual process of the pressing force of the rolling component, avoiding sudden increase in pressure and causing skin damage; in the horizontal direction, the smooth displacement guided by the streamline curved surface makes the liquid medicine coverage more coherent, eliminating the smearing blind area generated by the sudden change of the track of the traditional device, and significantly improving the uniformity of drug distribution and the epidermal absorption efficiency.

[0011] Further, the placement component includes an electric control lifting column fixedly connected to the top of the base, and an arc-shaped support seat is fixedly connected to the output end of the electric control lifting column.

[0012] Beneficial effects: By adjusting the initial distance between the arc support seat and the rolling component assembly through the electric control lifting column, it ensures that when the arms of different people are placed on the arc support seat and ready for medication application, the rolling component contacts the scar on the arm and the initial pressure is appropriate, ensuring the accuracy of subsequent medication application.

[0013] Furthermore, the rolling component includes a fixed seat fixedly connected to the bottom end of the lifting rod. A medication application roller is rotatably connected to the bottom of the fixed seat, and a plurality of spraying components for spraying liquid medicine onto the medication application roller are symmetrically and fixedly connected to the top end of the fixed seat.

[0014] Beneficial effects: The symmetric spraying components and the rotation of the medication application roller form a dynamic drug film synchronization system. Through the synergistic effect of centrifugal force and surface tension, the directional slow release of the liquid medicine is realized, which not only avoids the splashing caused by jet impact, but also ensures the uniform infiltration of the liquid medicine on the roller surface, eliminating the smearing blind area.

[0015] Furthermore, each spraying component includes a medicine storage chamber fixedly connected to the top end of the fixed seat and a spraying pump. The input ends of the spraying pumps are all communicated with the medicine storage chamber.

[0016] Beneficial effects: The modular medicine storage chamber and the independent spraying pump form a closed-loop drug supply system. Combined with the synchronous rolling of the medication application roller, it forms a dual effect of atomization - rolling, which not only avoids the volatilization pollution caused by open drug supply, but also suppresses the rebound and scattering of micro drops through the inertial cancellation mechanism.

[0017] Furthermore, the output end of the spraying pump is communicated to the bottom end of the fixed seat and is located directly above the medication application roller.

[0018] Beneficial effects: The directional vertical spraying path and the rotation of the medication application roller form an instantaneous cavity adsorption effect. Utilizing the tangential acceleration of the roller body rotation to realize the instant extension of the liquid film, it effectively offsets the dripping tendency caused by gravity. At the same time, it suppresses the atomization rebound through the dynamic matching of the jet angle and the roller speed, thereby evenly applying the liquid medicine to the scar of the patient.

[0019] Furthermore, the surface of the medication application roller is covered with a sponge layer.

[0020] Beneficial effects: The multi-level slow release structure of the sponge layer evenly adsorbs the liquid medicine through capillary action and realizes pressure-sensitive gradient release during rolling contact. It not only buffers the mechanical extrusion impact to avoid secondary damage to the scar, but also ensures sufficient infiltration of the deep folded parts.

[0021] Furthermore, the top end of the lifting rod is always located below the guiding rotating body.

[0022] Beneficial effects: The spatial decoupling design of the lifting rod and the guiding rotating body eliminates the risk of trajectory interference with the spiral guide rail during vertical movement through axial degree-of-freedom constraint, ensures the complete reproduction of the streamline trajectory, and at the same time reduces the wear of the guide rail caused by reciprocating impact.

[0023] Furthermore, the driving assembly includes a motor disposed inside the support frame, and the output shaft of the motor is coaxially and fixedly connected to the driving shaft.

[0024] Beneficial effects: The motor ensures real-time synchronization of the angular displacement of the spiral guide rail and the linear velocity of the rolling assembly through torque rigid transmission, avoiding skin shear damage caused by trajectory deviation, and at the same time reducing the interference of gear meshing noise to the medical environment.

[0025] Furthermore, it further includes a controller, and the motor, the spraying pump and the electric control lifting column are all electrically connected to the controller.

[0026] Beneficial effects: The controller integrates multi-module collaborative logic, real-time calibrates the motion parameters and the drug administration dose through closed-loop feedback, dynamically optimizes the operation accuracy, and at the same time triggers protection mechanisms such as overload power-off and liquid medicine surplus warning to ensure the safety and adaptive adjustment ability of the treatment process.

[0027] Furthermore, a plurality of ventilation holes are provided on the surface of the arc-shaped support seat.

[0028] Beneficial effects: The design of the ventilation holes can provide air fluidity between the arm and the arc-shaped support seat during drug application, improve heat dissipation, and at the same time enable the excess liquid medicine on the arm to flow out quickly through the ventilation holes, ensuring the comfort of the arm.

[0029] The additional aspects and advantages of the present invention will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the present invention. Description of the Drawings

[0038] The following will be further described in detail through specific embodiments:

[0039] Embodiment:

[0040] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 : A medical beauty scar removal device includes a base 1 and a support frame 8. The support frame 8 is bolted to the top of the base 1, and a placement component for placing the arm to be treated is installed on the top of the base 1;

[0041] Specifically, the placement component includes an electric control lifting column 2 bolted to the top of the base 1. The output end of the electric control lifting column 2 is screwed with an arc-shaped support seat 3. The initial height of the arc-shaped support seat 3 is adjusted by the lifting of the electric control lifting column 2, so as to adapt to the thickness of the arms of different users, so that the subsequent medicine application mechanism can fully apply and press the scars on their arms. At the same time, a number of ventilation holes are provided on the surface of the arc-shaped support seat 3 to improve the air permeability between the arc-shaped support seat 3 and the patient's arm, and at the same time quickly discharge some of the liquid medicine flowing down the arm onto the arc-shaped support seat 3 through the ventilation holes, improving the comfort during the medicine application process.

[0042] Inside the support frame 8, a transmission component is installed. At the lower end of the transmission component, a rolling component for applying medicine to the arm to be treated is installed. The transmission component is used to make the movement trajectory of the rolling component a streamline curve.

[0043] Inside the support frame 8, a driving component for providing driving force for the transmission component is provided. Specifically, the driving component includes a motor arranged inside the support frame 8.

[0044] Specifically, the rolling component includes a fixed seat 5 fixedly connected to the bottom end of the transmission component. A medicine application roller 4 is rotatably connected to the bottom of the fixed seat 5. A sponge layer is covered on the surface of the medicine application roller 4. Symmetrically and fixedly connected to the top end of the fixed seat 5 are spraying components for spraying liquid medicine onto the medicine application roller 4. Each spraying component includes a medicine storage bin 6 and a spraying pump connected to the top end of the fixed seat 5 by screws. The input ends of the spraying pumps are all communicated with the medicine storage bin 6. The output ends of the spraying pumps are communicated to the bottom end of the fixed seat 5 and are located directly above the medicine application roller 4. Through the directional vertical spraying path and the rotation of the medicine application roller 4, an instantaneous cavity adsorption effect is formed. The tangential acceleration of the rotation of the roller body is used to realize the instant extension of the liquid film, effectively offsetting the dripping trend caused by gravity. At the same time, the atomization rebound is suppressed by the dynamic matching of the jet angle and the roller speed, so as to evenly apply the liquid medicine to the scar of the patient.

[0045] It further includes a controller. The motor, the spraying pump, and the electric control lifting column 2 are all electrically connected to the controller.

[0046] In some practical applications, after the distance between the medicine application roller 4 and the arm support is adjusted (before medicine application), it is difficult to change its original horizontal linear movement route during the subsequent medicine application process. For the human arm, its surface is a curved surface (normal natural physiological curvature), so there is a certain height difference. If the medicine application roller 4 performs subsequent medicine application at the initial point height, when the initial point is a low point (lower than the subsequent medicine application point), as the medicine application roller 4 runs, the extrusion and frictional force of the medicine application roller 4 on the subsequent scar will gradually increase. For some relatively new scars, it is easy to cause these scars to crack and bleed, resulting in new wounds and the medicine entering these wounds, which is not conducive to the removal of the scars and will also increase the discomfort of the patient.

[0047] For the above problems, in this solution, specifically, the transmission component includes a driving shaft 12 that is coaxially and key-connected to the output shaft of the motor. One end of the driving shaft 12 away from the motor is located inside the support frame 8 and is integrally formed with a guiding rotating body 11 coaxially. A spiral guide rail with a gradually changing pitch is welded on the surface of the guiding rotating body 11 along its central axis direction. A guiding wheel 13 is slidably engaged with the spiral guide rail. The guiding wheel 13 is rotatably connected to a lifting rod 7. The top end of the lifting rod 7 is always located below the guiding rotating body 11. The bottom end of the lifting rod 7 is screwed to the top end of the fixed seat 5. A sliding block 9 that is slidably engaged with the lifting rod 7 is sleeved around the middle of the lifting rod 7. One side of the sliding block 9 is horizontally and fixedly connected to a moving rod 10 that is slidably engaged with the support frame 8; the guiding rotating body 11 is a cylinder and its cylindrical surface is a streamline-shaped curved surface.

[0048] The specific implementation process is as follows: Place the patient's arm on the arc-shaped support seat 3, and the controller adjusts the height of the electric control lifting column 2 according to the thickness of the arm so that the scar area is aligned with the action range of the medicine application roller 4.

[0049] The controller starts the motor (forward / backward rotation), driving the driving shaft 12 to rotate (forward / backward rotation), and the guiding rotating body 11 integrated with the driving shaft 12 rotates synchronously (forward / backward rotation). The spiral guide rail with a gradually changing pitch on the surface of the guiding rotating body 11 starts to push the guiding wheel 13 to move. When the guiding wheel 13 slides along the spiral guide rail, it drives the lifting rod 7 to generate a vertical reciprocating motion. At the same time, due to the gradually changing pitch, the lifting rod 7 generates a horizontal displacement through the sliding block 9 - moving rod 10 structure, and due to the streamline-shaped cylindrical surface of the guiding rotating body 11, the motion vectors of the three (the lifting rod 7, the sliding block 9, and the moving rod 10) are superimposed, making the medicine application roller 4 present a streamline-shaped curved trajectory to conform to the curved shape of the arms of the general population. For example, the spiral guide rail with a gradually changing pitch of the guiding rotating body 11 (such as the pitch gradually increasing from 5 mm to 15 mm) is combined with the curvature of the streamline-shaped cylindrical surface (curvature radius R = 50 - 80 mm) to generate an ergonomic motion path, so that the distribution of the medicine application pressure conforms to the viscoelastic response curve of the scar tissue.

[0050] Moreover, through these continuous and stable motion modes, not only can the scar be continuously pressed during medicine application to fully cover the scar, playing an auxiliary treatment role, solving the problem in the prior art of non-continuous smearing and pressing on the scar resulting in uneven application of the medicine, but also reducing the possibility of the liquid medicine being flung away when part of the pressing action requires the medicine application roller 4 to be lifted a certain distance from the arm scar and then dropped for pressing (such as the revolution of the medicine application roller 4).

[0051] Based on the principle and motion process of the device described in the above embodiments, the comparison with the traditional device is as follows:

[0052] Table 1 - Comparison Table of Evaluation Indicators

[0053]

[0054] In the traditional device, due to linear motion, pressure concentrates on the convex part. In the present invention, through the coupled motion of a spiral guide rail with a gradually changing pitch (5 → 15 mm) and a streamlined cylindrical surface (R = 65 mm), the medicine application roller 4 dynamically fits the curvature of the arm, and the pressure fluctuation is reduced by about 63%. At the same time, the 15° tangential injection angle of the directional spraying unit is dynamically matched with the rotation speed of the medicine application roller 4 (30 - 60 rpm) to form a continuous liquid film and reduce dripping; the gradient pore structure of the sponge layer (porosity 65%) further adsorbs the residual medicine liquid, and the waste is reduced by more than 41%. Moreover, the continuous streamlined pressing trajectory increases the drug penetration depth by 1.5 - 2.3 times and avoids micro-damage caused by local overpressure.

[0055] Obviously, the above-mentioned embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
