Description

Technical Field

[0001] The present invention belongs to the technical field of freckle removal devices, and more specifically, particularly relates to a freckle removal device for medical whitening. Background Art

[0002] In the existing technical field of freckle removal, there are a series of problems to be solved urgently, which affect the freckle removal effect, operation safety and patient experience.

[0003] Traditional laser freckle removal devices perform poorly in terms of positioning accuracy. When operators perform freckle removal operations, it is difficult to accurately find the specific position where freckles need to be removed, which may lead to deviation of the laser irradiation position, not only affecting the freckle removal effect, but also possibly causing unnecessary damage to the surrounding normal skin tissue. Moreover, there are no effective auxiliary positioning means, mainly relying on the experience and naked eye observation of operators, and the accuracy and consistency of each operation cannot be guaranteed.

[0004] In terms of the protection of the laser head by the device, there are obvious deficiencies in the existing technology. The laser head, as a key component of the freckle removal device, is easily interfered by external environmental factors during operation, such as dust, water vapor, etc. These factors may affect the emission accuracy and stability of the laser, thereby reducing the success rate of the freckle removal operation. At the same time, the laser head also lacks reliable protection measures when not in use, and is easily damaged due to accidental collisions, etc., increasing the equipment maintenance cost and downtime.

[0005] The comfort of patients during freckle removal treatment is also an important issue. Traditional freckle removal devices often lack a user-friendly design when contacting the patient's face. For example, the way the device fits with the face is not reasonable enough, which may bring an uncomfortable squeezing feeling to the patient. Moreover, during the freckle removal process, the laser irradiation generates heat, which easily causes a burning sensation and pain on the patient's skin, and the existing devices usually lack effective cooling measures to relieve this discomfort.

[0006] In addition, the adaptability of existing freckle removal devices to different patient facial contours is poor. Everyone's facial shape and curve are different, and most traditional devices use contact parts with a fixed shape, which cannot fit various facial contours well, not only affecting the freckle removal effect, but also possibly further reducing the patient's comfort.

[0007] In summary, the current freckle removal technology has many defects in terms of positioning accuracy, laser head protection, patient comfort and facial adaptability, and cannot meet people's needs for safe, efficient and comfortable freckle removal treatment. Summary of the Invention

[0008] In order to solve the above technical problems, the present invention provides a freckle removal device for medical whitening to solve the above problems.

[0009] A freckle-removing device for medical whitening, including a picosecond pulsed laser. A fixing frame is fixedly installed on the top of the picosecond pulsed laser. A connection line group is installed at the front end of the picosecond pulsed laser. A laser head is fixedly installed at the end of the connection line group. The fixing frame is used to fix a rubber connection sleeve. An operation screen is arranged above the picosecond pulsed laser. A pulley group is arranged at the bottom of the picosecond pulsed laser. At least two perspective slots are opened on the surface of the conical protective cover. The perspective slots are used to observe the position of the laser head. A rubber connection sleeve is fixedly sleeved on the surface of the connection line group. A middle connection frame is fixedly sleeved at the end of the rubber connection sleeve. A conical protective cover is movably sleeved on the surface of the laser head. An elastic connection mechanism is installed between the conical protective cover and the middle connection frame. A slidable curved rubber frame is arranged at the end of the conical protective cover. Side fixing frames are fixedly installed on both the left and right sides of the conical protective cover. A slidable rubber push panel is installed at the end of each side fixing frame. At least two semiconductor cooling components are fixedly installed on the inner wall of the conical protective cover; the elastic connection structure includes a middle connection frame and a back fixing frame.

[0010] Preferably, a conversion sleeve is fixedly sleeved on the surface of the rubber connection sleeve. The middle connection frame is fixedly sleeved at the end of the rubber connection sleeve. The end of the conical protective cover is fixedly connected to the back fixing frame. At least two first springs are fixedly installed at the end of the back fixing frame. The end of each first spring passes through the middle connection frame and is slidably connected to the middle connection frame. The end of each first spring is slidably inserted into the conversion sleeve. A first sliding rod is sleeved on the surface of each first spring, and each first sliding rod is located between the middle connection frame and the back fixing frame. A line conduit is arranged between the back fixing frame and the middle connection frame. The line conduit is connected to the lines inside the connection line group and is used to supply electrical energy to the three semiconductor cooling components.

[0011] Preferably, a curved sliding groove is opened at the end of the conical protective cover. The curved rubber frame is slidably installed inside the curved sliding groove. The upper and lower sides of the end of the curved rubber frame and the conical protective cover are concave inward, and the left and right sides of the end of the curved rubber frame and the conical protective cover are convex outward. At least two third sliding rods are fixedly installed on the back of the curved rubber frame. Each third sliding rod is slidably installed inside the curved sliding groove. At least two third springs are fixedly installed between the curved rubber frame and the inner wall of the curved sliding groove, and each third spring is sleeved outside the third sliding rod.

[0012] Preferably, at least two second sliding rods are fixedly installed on the back surface of each rubber push panel. Each second sliding rod slidably penetrates outside the side fixing frame, and a second spring is sleeved outside each second sliding rod. Each second spring is located between the side fixing frame and the rubber push panel. An arc surface is formed at the end of each rubber push panel. Each rubber push panel and the conical protective cover are in an inclined state, and the ends of the two rubber push panels are inclined towards the center point of the conical protective cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when performing freckle removal operation on a user, the conical protective cover is placed over the freckle removal area of the user. Then, the device is started, and the laser head at the end of the connection line group performs laser freckle removal on the user's face. The operator can observe the position of the laser head through the perspective slots formed on the surface of the conical protective cover. A conical protective cover is movably sleeved on the surface of the laser head. An elastic connection mechanism is installed between the conical protective cover and the central connection frame. A slidable curved rubber frame is provided at the end of the conical protective cover. Side fixing frames are fixedly installed on both the left and right sides of the conical protective cover. A slidable rubber push panel is installed at the end of each side fixing frame. When the conical protective cover contacts the user's face, the two rubber push panels will push and pull the user's face from both sides. At this time, it can help the laser head find the freckle removal position more accurately, thereby improving the freckle removal ability.

[0014] In the present invention, the operator holds the rubber connection sleeve. When the conical protective cover contacts the user's face, since there is a certain distance between the end of the conical protective cover and the laser head, the conical protective cover will move under the reaction force. The movement of the conical protective cover drives the movement of the back fixing frame. The movement of the back fixing frame drives the movement of the three first springs. The ends of the three first springs slide inside the central connection frame and the conversion sleeve. The conical protective cover is designed to be slidable. During freckle removal, the conical protective cover can form a protective cover for the laser head, reducing the influence of the external environment on the laser head and improving the success rate of the freckle removal operation. At the same time, the conical protective cover can drive the two rubber push panels to contact the user's face first, thereby improving the function of the rubber push panels.

[0015] In the present invention, when the laser head is not in use, the three first sliding rods drive the back fixing frame and the conical protective cover to move outwards by elastic force. The end of the conical protective cover protrudes from the end of the laser head and forms a certain distance. At this time, the conical protective cover can play a good protective role for the curved chute, effectively preventing the laser head from being damaged.

[0016] In the present invention, when removing freckles from the user's face, the end of the conical protective cover fits against the user's face. Since the curved rubber frame is supported by the third spring, the curved rubber frame first fits against the user's face. At this time, the curved rubber frame first performs a circular extrusion on the user's face. Both the upper and lower sides of the curved rubber frame and the conical protective cover are concave, while the two sides are convex. Therefore, it can fit more closely to the user's face. When the curved rubber frame performs a circular extrusion on the user's face, it can improve the accuracy of the subsequent fitting of the laser head to the face. Moreover, when the curved rubber frame fits against the face, it can reduce the discomfort caused by the conical protective cover squeezing the face, improving the comfort during freckle removal. After the conical protective cover fits against the face, the three semiconductor cooling components in the inner ring of the conical protective cover fit against the face. The three semiconductor cooling components quickly cool down the face, and do not affect the freckle-removing area of the laser head. They quickly cool down the three weeks around the freckle-removing area, which can reduce the discomfort of the user during freckle removal.

[0017] In the present invention, after the conical protective cover fits against the face, the two rubber push panels on both sides of the conical protective cover come into contact with the face. Since the two rubber push panels are inclined towards the center of the conical protective cover, after the two rubber push panels come into contact with the face, they will receive the component forces from the face. And the rubber push panels are supported by the elastic forces of multiple second springs. Therefore, when the rubber push panels move, they will pull the facial skin, horizontally pulling the skin on both sides of the freckle-removing area. At this time, the skin of the freckle-removing area becomes more taut, so that when the laser head removes freckles, it can penetrate more deeply, improving the ability to remove freckles.

[0020] The following further describes in detail the implementation manners of the present invention in conjunction with the attached drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] Please refer to Figures 1 - 9 , the present invention provides a freckle-removing device for medical whitening, including a picosecond pulse laser 1. A fixed frame 16 is fixedly installed at the top of the picosecond pulse laser 1. A connection line set 14 is installed at the front end of the picosecond pulse laser 1. A laser head 15 is fixedly installed at the end of the connection line set 14. The fixed frame 16 is used to fix the rubber connection sleeve 17. An operation screen 13 is arranged above the picosecond pulse laser 1. A pulley set 12 is arranged at the bottom of the picosecond pulse laser 1. At least two perspective slots 24 are opened on the surface of the conical protective cover 23. A transparent glass is installed in the perspective slot 24. The perspective slot 24 is used to observe the position of the laser head 15. A rubber connection sleeve 17 is fixedly sleeved on the surface of the connection line set 14. A central connection frame 19 is fixedly sleeved at the end of the rubber connection sleeve 17. When performing freckle-removing operations on users, the conical protective cover 23 is covered on the freckle-removing part of the user. Subsequently, the device is started. The laser head 15 at the end of the connection line set 14 performs laser freckle-removing on the user's face. The operator can observe the position of the laser head 15 through the perspective slot 24 opened on the surface of the conical protective cover 23. The conical protective cover 23 is movably sleeved on the surface of the laser head 15. An elastic connection mechanism is installed between the conical protective cover 23 and the central connection frame 19. A slidable curved rubber frame 26 is arranged at the end of the conical protective cover 23. Side fixed frames 29 are fixedly installed on both the left and right sides of the conical protective cover 23. A slidable rubber push panel 3 is installed at the end of each side fixed frame 29. When the conical protective cover 23 contacts the user's face, the two rubber push panels 3 will push and pull the user's face on both sides. At this time, it can help the laser head 15 find the freckle-removing position more accurately, thereby improving the freckle-removing ability. At least two semiconductor cooling components 34 are fixedly installed on the inner wall of the conical protective cover 23; the elastic connection structure includes a central connection frame 19 and a rear fixed frame 2.

[0022] A conversion sleeve 18 is fixedly sleeved on the surface of the rubber connecting sleeve 17. The middle connecting frame 19 is fixedly sleeved at the end of the rubber connecting sleeve 17. The end and the back fixing frame 2 of the conical protective cover 23 are fixedly connected. At least two first springs 22 are fixedly installed at the end of the back fixing frame 2. The end of each first spring 22 passes through the middle connecting frame 19 and is slidably connected to the middle connecting frame 19. The end of each first spring 22 is slidably inserted into the conversion sleeve 18. When the operator holds the rubber connecting sleeve 17 and the conical protective cover 23 touches the user's face, since there is a certain distance between the end of the conical protective cover 23 and the laser head 15, the conical protective cover 23 will move under the reaction force. The movement of the conical protective cover 23 drives the back fixing frame 2 to move. The movement of the back fixing frame 2 drives the three first springs 22 to move. The ends of the three first springs 22 slide inside the middle connecting frame 19 and the conversion sleeve 18. The conical protective cover 23 is designed to be slidable. During freckle removal, the conical protective cover 23 can form a protective cover for the laser head 15, reduce the influence of the external environment on the laser head 15, and improve the success rate of the freckle removal operation. At the same time, the conical protective cover 23 can drive the two rubber push panels 3 to contact the user's face first, thereby improving the function of the rubber push panels 3. When the laser head 15 is not in use, the three first sliding rods 21 drive the back fixing frame 2 and the conical protective cover 23 to move outwards by elastic force. The end of the conical protective cover 23 protrudes from the end of the laser head 15 and there is a certain distance. At this time, the conical protective cover 23 can play a good protective role for the curved chute 25 and effectively prevent the laser head 15 from being damaged. A first sliding rod 21 is sleeved on the surface of each first spring 22, and each first sliding rod 21 is located between the middle connecting frame 19 and the back fixing frame 2. A line conduit 37 is arranged between the back fixing frame 2 and the middle connecting frame 19. The line conduit 37 is connected to the lines inside the connection line group 14 and is used to supply electrical energy to the three semiconductor cooling components 34.

[0023] The end of the conical protective cover 23 is provided with a curved chute 25. The curved rubber frame 26 is slidably installed inside the curved chute 25. The upper and lower sides of the end of the curved rubber frame 26 and the conical protective cover 23 are both concave inward, and the left and right sides of the end of the curved rubber frame 26 and the conical protective cover 23 are both convex outward. At least two third sliding rods 35 are fixedly installed on the back of the curved rubber frame 26. When removing freckles from the user's face, the end of the conical protective cover 23 is attached to the user's face. Since the curved rubber frame 26 is supported by the third spring 36, the curved rubber frame 26 is first attached to the user's face. At this time, the curved rubber frame 26 first performs a circular extrusion on the user's face. Moreover, the upper and lower sides of the curved rubber frame 26 and the conical protective cover 23 are both concave, while the two sides are convex, so it can fit the user's face more closely. When the curved rubber frame 26 performs a circular extrusion on the user's face, it can improve the accuracy of the subsequent fitting of the laser head 15 to the face. And when the curved rubber frame 26 is attached to the face, it can reduce the discomfort of the conical protective cover 23 pressing on the face and improve the comfort during freckle removal. After the conical protective cover 23 is attached to the face, the three semiconductor cooling components 34 on the inner ring of the conical protective cover 23 are attached to the face. The three semiconductor cooling components 34 quickly cool the face and do not affect the freckle-removing part of the laser head 15. They quickly cool the three weeks around the freckle-removing part, which can reduce the discomfort of the user during freckle removal. Each third sliding rod 35 is slidably installed inside the curved chute 25. At least two third springs 36 are fixedly installed between the curved rubber frame 26 and the inner wall of the curved chute 25, and each third spring 36 is sleeved outside the third sliding rod 35.

[0024] At least two second sliding rods 32 are fixedly installed on the back of each rubber push panel 3. Each second sliding rod 32 slidably penetrates outside the side fixing frame 29, and a second spring 33 is sleeved outside each second sliding rod 32. Each second spring 33 is located between the side fixing frame 29 and the rubber push panel 3. An arc surface 31 is provided at the end of each rubber push panel 3. Each rubber push panel 3 and the conical protective cover 23 are in an inclined state, and the ends of the two rubber push panels 3 are inclined towards the center point of the conical protective cover 23. After the conical protective cover 23 is attached to the face, the two rubber push panels 3 on both sides of the conical protective cover 23 contact the face. Since the two rubber push panels 3 are inclined towards the center of the conical protective cover 23, after the two rubber push panels 3 contact the face, they will receive the component forces from the face. And the rubber push panels 3 are supported by the elastic forces of multiple second springs 33. Therefore, the rubber push panels 3 will pull the facial skin during the movement process, horizontally pulling the skin on both sides of the freckle-removing part. At this time, the skin of the freckle-removing part becomes tighter, so that when the laser head 15 removes freckles, it can penetrate more deeply and improve the freckle-removing ability.

[0025] Working principle: When removing facial freckles for a user, the operator holds the rubber connecting sleeve 17, aligns the conical protective cover 23 with the freckle-removing area on the face. Subsequently, the curved rubber frame 26 contacts the face first. The two rubber push panels 3 simultaneously perform a horizontal pull on the facial skin, and the three semiconductor cooling components 34 rapidly cool the face. Then, the laser head 15 is pressed downward forcefully to make the laser head 15 fit the skin. The picosecond pulsed laser 1 operates to perform laser freckle removal on the face through the laser head 15.
