Description

Technical Field

[0001] The present invention relates to the technical field of medical cosmetology, and in particular to a scar repair robot used for medical cosmetology. Background Art

[0002] Laser cosmetic treatments have emerged in recent years as a new cosmetic procedure. This method can eliminate facial wrinkles and, using appropriate laser irradiation, make the skin smoother and more refined. It can also treat acne, moles, and age spots. Laser cosmetic treatments use a laser beam of a specific wavelength through the epidermis and dermis, destroying pigment cells and pigment granules. The fragments are then processed and absorbed by the body's macrophages, resulting in a safe, scar-free, and highly effective whitening treatment.

[0003] For example, the patent application number CN202310607871.9 discloses "a laser scar repair device", which includes a two-stage micro-stretching mechanism, an elastic telescopic pre-tightening mechanism and a laser repair mechanism, and the two-stage micro-stretching mechanism is slidably arranged in the elastic telescopic pre-tightening mechanism.

[0004] However, when the above-mentioned device is in use, the two-stage micro-stretching mechanism deforms itself, and when it contacts and presses the skin, the skin within the range is slightly stretched. However, after the skin is stretched, due to the lack of a fixing mechanism, the stretched skin is prone to loosening, which is not conducive to the subsequent laser repair quality. In addition, the stretched scar skin is also prone to multiple horizontal wrinkles, and the wrinkle angle at the scar cannot be changed in time, which is not conducive to the laser repair quality of the scar.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a mechanical arm is provided to move the electric push rod 1, the fixed plate and the laser head to the upper side of the patient's skin scar area, and the electric push rod 1 is started to push the fixed plate, the laser head, the rack, the support plate and the pulling roller down, so that the lower end of the pulling roller abuts on both sides of the patient's skin scar, and the motor 1 is started to drive the pulling roller and the horizontal bar to rotate. The horizontal bar facilitates to pull the two sides of the patient's skin apart, so that the patient's skin scar area is completely unfolded, which is convenient for the laser head to perform laser repair on the scar.

[0017] 2. In the present invention, the second electric push rod is started to drive the rack, support plate and pulling roller on one side to slide left and right on the fixed plate, driving the transmission gear to rotate. The transmission gear drives the rack, support plate and pulling roller on the other side to move towards or away from the fixed plate, which is convenient for adjusting the distance between the pulling rollers on both sides according to the size of the skin scar area, and has a wide applicability.

[0018] 3. In the present invention, after the pulling roller pushes the skin aside, the electric push rod is started to drive the metal plate and the rubber sheet to descend. The rubber sheet gradually contacts the skin and is squeezed and deformed by the skin. The gas in the rubber sheet is gradually emptied through the provided air holes and then stops. The screw is then rotated to drive the sealing plug to rotate and descend on the bracket to block the air holes. At this time, the rubber sheet and the metal plate can form a suction cup, which is convenient for adsorbing and fixing the skin. It effectively prevents the skin from rising and falling when the patient breathes after the pulling roller pushes the skin aside, causing the skin to become loose during the laser repair process, resulting in the scar being unable to fully unfold, thereby ensuring the quality of scar repair.

[0019] 4. In the present invention, the starting motor 2 drives the rotating shaft to rotate through the set gear set, and the rotating shaft drives the electric push rod 3, the metal plate and the rubber sheet to rotate. Since the rubber sheet is tightly adsorbed on the skin, it will also drive the skin to rotate slightly, making it convenient to make the skin scar deform at different angles, which is beneficial to show the folds of the scar under the laser head, thereby improving the quality of scar repair.

[0020] 5. In the present invention, the electric push rod 4 is started to drive the anti-loosening plate to descend, and the anti-loosening plate presses and fixes the front and rear sides of the rubber sheet, thereby preventing the skin from being deformed when the rubber sheet rotates, and gaps from appearing at the front and rear sides of the rubber sheet and the skin adsorption connection, resulting in the failure of the rubber sheet adsorption and the inability to drive the skin to rotate.

[0021] 6. In the present invention, the electric push rod 5 is started to drive the movable plate toward the direction of the laser head. The movable plate drives the rotating rod, the winding reel, and the cleaning blade rod to move synchronously, so that the cleaning blade rod gradually approaches and contacts the lower end face of the laser head. The upper end of the cleaning blade rod is made of flexible material. The cleaning blade rod will deform and gradually pass through the lower end face of the laser head. The provided cleaning blade rod is convenient for cleaning impurities and dust on the lower end face of the laser head, thereby ensuring the quality of subsequent repair of the laser head.

[0022] 7. In the present invention, when the wire rope is moved toward the laser head by the winding drum, the wire rope wound on the winding drum will be unwound, and then the winding drum drives the rotating rod and the cleaning leaf rod to rotate on the movable plate, compressing the torsion spring. The rotation of the cleaning leaf rod improves the cleaning effect of the lower end face of the laser head, so that the lower end face of the laser head remains clean.

[0023] 8. In the present invention, the collection box is provided to collect dust and impurities dropped when the cleaning blade rod cleans the laser head, and is convenient for centralized cleaning. Pull the fixed rod tension spring outward, and the fixed rod is removed from the cleaning blade rod. The collection box can be directly slid downward from the cleaning blade rod to be removed.
