Description

Technical Field

[0001] This invention relates to the field of biomedical engineering technology, specifically to a laser-assisted skin rejuvenation treatment device. Background Technology

[0002] Against the backdrop of the rapid iterative development of the biomedical engineering industry, laser diagnostic and treatment equipment, as a core tool in the intersection of medical aesthetics and clinical medicine, has become an important branch of the biomedical engineering industry's clinical application. Laser skin treatment devices utilize the laser's explosive effect to achieve routine clinical treatment of pigmented skin diseases: the laser can effectively penetrate the epidermis to reach the pigment clusters in the dermis, where it is preferentially absorbed by the pigment. Due to the extremely short laser action time (only a few nanoseconds) and extremely high energy (each pulse energy can reach 300-800mJ), the pigment clusters rapidly expand and disintegrate into fine particles after instantly absorbing the high-energy laser. These particles are then phagocytosed by macrophages and excreted through the lymphatic system, thus gradually fading and even eliminating the pigmentation.

[0003] However, judging from the current state of clinical application in the biomedical engineering industry, most mainstream skin aesthetic laser treatment devices on the market adopt a fixed structural design. The device structure design fails to meet the precise and adjustable clinical needs of the biomedical engineering industry. The relative distance between the laser output end and the skin is difficult to adjust flexibly according to treatment needs. In actual clinical operation, the operator can only passively adjust the treatment height by hand-held mobile device or changing the patient's position. This not only increases the complexity and instability of clinical operation, but also easily causes the spot energy density to deviate from the expected set value due to improper laser action distance, resulting in differences in efficacy for different patients and different treatment sites. It is difficult to ensure the consistency of skin laser treatment effect, which restricts the standardization and intelligent application of medical aesthetic diagnosis and treatment equipment in the biomedical engineering industry.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] This invention provides a technical solution: such as Figure 1 - Figure 10 The device shown is a laser-assisted skin rejuvenation treatment device, including a housing 1 and a laser treatment component 7 mounted on the housing 1. A mounting plate 9 is fixedly connected to the side of the laser treatment component 7. An extension rod 17 is slidably connected to the laser treatment component 7. A laser treatment head 16 is fixedly connected to the bottom end of the extension rod 17. A fixing frame 14 is fixedly connected to the bottom of the laser treatment component 7. A bottom ring 15 is fixedly connected to the bottom of the fixing frame 14. A baffle 22 is slidably connected to the inner wall of the fixing frame 14. A distance sensor 47 is fixedly installed at the end of the baffle 22 away from the laser treatment head 16. An air inlet pipe 26 and an air outlet pipe 48 are fixedly installed on the body of the laser treatment component 7. The air outlet pipe 48 is located above the air inlet pipe 26. The air inlet pipe 26 is provided with a block 45 for controlling the opening and closing of the air inlet pipe 26 and a regulating valve core 46 for controlling the flow rate of the medium in the pipe. The block 45 is located at the end of the air inlet pipe 26 near the laser treatment component 7, and the regulating valve core 46 is located at the end of the air inlet pipe 26 away from the laser treatment component 7.

[0021] In this invention, the housing 1 is the main base of the entire laser-assisted skin beauty treatment device, bearing the load and installation of all components. The laser treatment component 7 is the core functional component of the device, specifically responsible for laser emission and beauty treatment operations. A mounting plate 9 is fixedly connected to the side of the laser treatment component 7. The mounting plate 9 can serve as a handle structure for medical personnel to operate, and also provide a fixed mounting carrier for the components of isolation chamber 11, isolation chamber 22, transmission chamber 13, and transmission chamber 25. An extension rod 17 is vertically slidably assembled inside the laser treatment component 7. The extension rod 17 can make vertical linear sliding movements inside the laser treatment component 7. A laser treatment head 16 is fixedly installed at the bottom of the extension rod 17. The laser treatment head 16 is directly close to the patient's skin and outputs laser energy to achieve beauty treatments such as freckle removal and skin rejuvenation.

[0022] The bottom of the laser treatment component 7 is supported by a mounting frame 14. The mounting frame 14 has an enclosed frame structure, which can protect and isolate the area around the laser treatment head 16, and provide installation points for auxiliary components such as the baffle 22 and the clamp 23. The bottom end of the mounting frame 14 is fixedly connected to a bottom ring 15, which can be directly attached to the patient's skin surface. This can quickly locate the treatment area and block the laser light, preventing laser scattering from accidentally damaging the surrounding normal skin tissue. A baffle 22 is slidably installed on the inner side wall of the mounting frame 14. The baffle 22 can slide laterally inside the mounting frame 14. A distance sensor 47 is fixedly installed at the end of the baffle 22 away from the laser treatment head 16. The distance sensor 47 is used to sense and detect the vertical distance between the laser treatment head 16 and the patient's skin surface in real time, providing a precise distance signal for the automatic start and stop of the device and the opening and closing of the baffle.

[0023] An inlet pipe 26 and an outlet pipe 48 are fixedly installed on the outer wall of the laser treatment component 7. The outlet pipe 48 is positioned above the inlet pipe 26, and the two work together to form a closed cooling airflow circulation channel. Inside the inlet pipe 26, a plug 45 and a regulating valve core 46 are installed. The plug 45 is installed at the end of the inlet pipe 26 closest to the laser treatment component 7, mainly used to block or open the internal pipes of the inlet pipe 26. The regulating valve core 46 is installed at the end of the inlet pipe 26 furthest from the laser treatment component 7, and its function is to adjust the flow cross-sectional area of ​​the cooling medium, thereby controlling the medium flow rate and adapting to the heat dissipation requirements of the device under different operating power conditions.

[0024] refer to Figure 1 - Figure 10 A mounting bracket 2 is fixedly connected to the side of the housing 1, and a roller 3 is fixedly installed at the bottom of the mounting bracket 2. A placement bracket 4 for placing the laser treatment component 7 is fixedly installed on the side of the housing 1, and a pusher 8 is fixedly installed at the top of the housing 1. A handle cable 5 is fixedly connected to the side of the housing 1, and a connecting seat 6 is fixedly connected to the end of the handle cable 5. The laser treatment component 7 is fixedly installed on the connecting seat 6, and a cooling air pipe 10 is fixedly installed on the connecting seat 6. The cooling air pipe 10 is connected to the air inlet pipe 26. A limiting groove 18 is fixedly connected to the inner wall of the laser treatment component 7, and a limiting slide 19 is fixedly connected to the body of the extension rod 17. The limiting slide 19 slides in the groove of the limiting groove 18. An opening 20 is opened on the bottom wall of the laser treatment component 7, and a limiting plate 21 is fixedly connected to the body of the laser treatment head 16.

[0025] In this invention, a mounting bracket 2 is fixedly connected to the side of the housing 1. The mounting bracket 2 extends vertically downwards, and a roller 3 is fixedly installed at the bottom of the mounting bracket 2. The roller 3 can roll and rotate freely, making it convenient for the whole machine to be moved and repositioned in the treatment room. A placement rack 4 is also fixedly installed on the side of the housing 1. The placement rack 4 is a simple bracket structure, which is specifically used to place the laser treatment component 7 when the device is not in use, so as to achieve neat storage and avoid damage caused by random placement. A push handle 8 is fixedly installed at the top of the housing 1. Medical staff can directly hold the push handle 8 and easily push the whole machine to move its position. A handle cable 5 is fixedly connected to the side of the housing 1. The handle cable 5 serves the functions of line transmission and air circuit connection (the air circuit pipe is integrated in the handle cable 5, which is isolated from the line and can also be adhered by insulating tape, etc.). A connecting seat 6 is fixedly connected to the end of the handle cable 5, and the laser treatment component 7 is fixedly installed on the connecting seat 6. A cooling air pipe 10 is fixedly installed on the connecting seat 6. The cooling air pipe 10 is connected to the air inlet pipe 26, which can stably deliver the cooling air source stored inside the box 1 to the air inlet pipe 26. A limiting groove 18 is fixedly connected to the inner wall of the laser treatment component 7. The limiting groove 18 is a vertical integrated guide groove. A limiting slide 19 is fixedly connected to the body of the extension rod 17. The limiting slide 19 slides in close fit within the groove of the limiting groove 18. By relying on the engagement and limiting of the two, the extension rod 17 is constrained to only move vertically up and down, avoiding rotation, offset and jamming.

[0026] The diameter of the limiting plate 21 is larger than the diameter of the opening 20, thereby limiting the maximum extension length of the laser treatment head 16 and the extension rod 17, and preventing the laser treatment head 16 and the extension rod 17 from detaching from the laser treatment assembly 7.

[0027] refer to Figure 1 - Figure 10The mounting plate 9 is fixedly installed with isolation chamber 11 and isolation chamber 22 from bottom to top. A transmission chamber 25 is fixedly installed between isolation chamber 11 and the mounting frame 14. A transmission chamber 13 is fixedly installed between isolation chamber 22 and the laser treatment component 7. A drive gear 27 is rotatably connected inside transmission chamber 13. A transmission gear 1701 is fixedly connected to the body of the extension rod 17, meshing with the drive gear 27. A driven gear 28, meshing with the drive gear 27, is rotatably connected inside transmission chamber 13. A driven gear 28, meshing with the drive gear 27, is also rotatably connected inside transmission chamber 13. A first bevel gear 29 rotates coaxially with the moving gear 28. A second bevel gear 30 is meshed with the first bevel gear 29. A rotating shaft 31 is fixedly connected to the bottom end face of the second bevel gear 30. The bottom end of the rotating shaft 31 is fixedly connected to the regulating valve core 46. A positioning plate 44 is fixedly connected inside the isolation chamber 11. A sliding rod 42 that passes through the positioning plate 44 is fixedly connected to the bottom of the block 45. A fixing plate 41 is fixedly connected to the sliding rod 42 located below the positioning plate 44. A spring 43 is fixedly connected between the fixing plate 41 and the positioning plate 44. 3. A positioning plate 38 is fixedly connected inside the isolation chamber 11. A sliding rod 35 is inserted into the positioning plate 38 and slides along it. A fixing plate 36 is fixedly connected to the sliding rod 35 below the positioning plate 38. A spring 37 is fixedly connected between the fixing plate 36 and the positioning plate 38, and the spring 37 is sleeved on the sliding rod 35. A clamping plate 23 is fixedly connected to the fixing frame 14. A scraping part 24 is fixedly connected to the bottom surface of the clamping plate 23. A baffle 22 is fixedly connected to one end of the clamping plate 23. A rack 32 is placed inside the transmission chamber 25, and one end of the rack 32 is meshed with a drive gear 33. A T-shaped groove 2501 is provided on the top wall of the transmission chamber 25. A T-shaped block 3201 is fixedly connected to the upper surface of the rack 32. An arc-shaped block 34 is slidably connected at the connection gap between the transmission chamber 25 and the isolation chamber 11. The arc-shaped block 34 is fixedly connected to the bottom end of the sliding rod 35. A bent pipe 39 is fixedly connected to the inner wall of the isolation chamber 11. A pull rope 40 is fixedly connected between the bottom end of the sliding rod 42 and the lower part of the sliding rod 35. The pull rope 40 passes through the bent pipe 39.

[0028] In this invention, isolation chamber 11 and isolation chamber 2 12 are fixedly installed on the surface of the mounting plate 9 from bottom to top. Isolation chamber 11 and isolation chamber 2 12 are both closed cavity structures, which can isolate the internal precision transmission components such as gears, springs, and ropes from the outside world, preventing dust, dander, and moisture from entering the transmission gap and reducing component wear and failure. Transmission chamber 2 25 is fixedly installed between isolation chamber 11 and the fixed frame 14, and transmission chamber 13 is fixedly installed between isolation chamber 2 12 and the laser treatment component 7. Transmission chamber 1 13 and transmission chamber 2 25 are also closed shells, providing a safe and stable operating space for the internal gear transmission mechanism.

[0029] Inside the transmission chamber 13, a drive gear 27 is rotatably connected. A transmission gear 1701 is integrally formed and fixed on the body of the extension rod 17. The teeth of the transmission gear 1701 and the drive gear 27 mesh with each other. When the drive gear 27 rotates, it can drive the extension rod 17 to rise and fall synchronously through the transmission gear 1701. Inside the transmission chamber 13, a driven gear 28 that meshes with the drive gear 27 is also rotatably connected, realizing power splitting and steering transmission. Inside the transmission chamber 13, a first bevel gear 29 that rotates synchronously with the driven gear 28 on the same axis is rotatably connected. The first bevel gear 29 is vertically meshed with a second bevel gear 30, and the direction of power transmission is changed through the meshing of the bevel gears. A rotating shaft 31 is fixedly connected to the bottom end face of the second bevel gear 30.

[0030] The bottom end of the rotating shaft 31 is fixedly connected to the regulating valve core 46. Rotation of the rotating shaft 31 can directly drive the regulating valve core 46 to rotate, changing the opening range of the valve core. A positioning plate 44 is fixedly connected inside the isolation chamber 11. The positioning plate 44 is a horizontal flat plate support structure. A sliding rod 42 that penetrates the surface of the positioning plate 44 is fixedly connected to the bottom of the block 45. The sliding rod 42 can slide freely vertically on the positioning plate 44. A fixing plate 41 is fixedly connected to the rod of the sliding rod 42 located below the positioning plate 44. A spring 43 is fixedly connected between the fixing plate 41 and the positioning plate 44. The spring 43 is entirely sleeved on the rod of the sliding rod 42 and maintains the initial sealing state of the block 45 by its own elasticity.

[0031] Inside the isolation chamber 11, a positioning plate 38 is fixedly connected. A sliding rod 35 is vertically inserted and slidably connected to the surface of the positioning plate 38, allowing it to slide up and down. A fixing plate 36 is fixedly connected to the rod body of the sliding rod 35, which is located below the positioning plate 38. A spring 37 is fixedly connected between the fixing plate 36 and the positioning plate 38. The spring 37 is sleeved on the outside of the rod body of the sliding rod 35 and remains in a relaxed state under normal conditions, stabilizing the initial position of the sliding rod 35. A clamping plate 23 is fixedly connected to the fixing frame 14. The clamping plate 23 has a groove-shaped structure, allowing the baffle 22 to slide and extend. A scraping part 24 is fixedly connected to the bottom surface of the clamping plate 23, and the scraping part 24 is set to fit against the detection end face of the ranging sensor 47.

[0032] A rack 32 is fixedly connected to one end of the baffle 22 inside the clamping plate 23. The rack 32 extends into the transmission chamber 25 and meshes with the drive gear 33. A T-slot 2501 is provided on the top wall of the transmission chamber 25. A T-block 3201 is fixedly connected to the upper surface of the rack 32. The T-block 3201 slides and engages inside the T-slot 2501, serving as a lateral guide and limit. An arc-shaped block 34 (with the arc surface of the arc-shaped block 34 facing the rack 32) is slidably connected at the connection gap between the transmission chamber 25 and the isolation chamber 11. The arc-shaped block 34 is fixedly connected to the bottom end of the sliding rod 35. A bent pipe 39 is fixedly connected to the inner wall of the isolation chamber 11. The bent pipe 39 serves as a steering limit. A pull rope 40 is fixedly connected between the bottom end of the sliding rod 42 and the lower part of the sliding rod 35. The pull rope 40 bends and passes through the inside of the bent pipe 39, realizing the power linkage between the two rods. It should be noted that the sliding rod 42 and the sliding rod 35 are set in parallel. The sliding rod 42, the sliding rod 35 and the pull rope 40 form a "U" shape. When the sliding rod 35 moves upward, the sliding rod 42 moves downward. The distance sensor 47 on the bottom surface of the baffle 22 measures the distance between the baffle 22 and the skin. The movement distance of the laser treatment head 16 is driven by the motor in the transmission chamber 13, which drives the gear 27. Only the number of motor rotations needs to be recorded or read to obtain the distance between the baffle 22 and the laser treatment head 16. The built-in program performs unified calculations to obtain the distance between the skin and the laser treatment head 16, eliminating the need to deploy multiple sensors.

[0033] Furthermore, relying on the cooperation of the bottom roller 3 and the top pusher 8, this device can be flexibly transported and placed between cosmetic departments and treatment wards, adapting to the needs of clinical use in multiple scenarios. All precision components such as transmission gears, springs, and ropes are housed in the closed cavities of isolation chamber 11, isolation chamber 22, transmission chamber 13, and transmission chamber 25. This not only avoids damage to components caused by bumps during daily operation, but also prevents skin flakes and dust generated by laser treatment from entering the transmission gaps, reducing jamming and malfunctions, and extending the service life of the equipment.

[0034] The vertical guiding structure of the limiting groove 18 and the limiting slide 19 ensures that the extension rod 17 remains vertical when adjusting its stroke, preventing swaying or deviation. This ensures precise and stable height adjustment of the laser treatment head 16. The bottom ring 15 features a flexible and conforming design that can adapt to the skin contours of different curvatures, such as the face, neck, and limbs. It provides a strong seal, accurately defining the treatment area while effectively blocking outward scattering of laser light and protecting surrounding normal skin from accidental laser damage.

[0035] The device adopts a mechanical linkage structure design, eliminating the need for medical staff to manually operate each component step by step. It relies on the mechanism to automatically sense and match the working status, making it simple and easy to operate and reducing the difficulty of manual operation. The distance sensor 47 monitors the distance in real time throughout the process. Only when the standard treatment distance is detected will the retraction be triggered to start treatment, thereby avoiding problems such as uneven light spot and deviation in treatment effect caused by improper distance. At the same time, the scraping part 24 moves synchronously with the baffle 22, automatically cleaning the surface of the distance sensor 47 probe to remove dirt, grease and dander. It can maintain distance measurement accuracy even after long-term use, without the need for frequent manual cleaning and maintenance.

[0036] Working principle: When staff need to use this skin beauty laser-assisted treatment device, they can push the handle 8 by hand, and the rollers 3 installed at the bottom of the mounting frame 2 will rotate, allowing the entire device to be smoothly moved to the designated position for beauty treatment. Once it is securely placed, treatment can begin. When the device is not in use, the laser treatment component 7 can be stably placed on the shelf 4 on the side of the housing 1 for storage, preventing accidental damage.

[0037] The connecting base 6 integrates a cooling air pipe 10, which is connected to the cooling air source inside the housing 1 via the handle cable 5. This continuously supplies cooling medium to the air inlet pipe 26, providing a source of heat dissipation for the laser treatment component 7. In actual clinical treatment, the user can easily hold and operate the laser treatment component 7 by directly gripping the mounting plate 9 as a handle for positioning and angle adjustment. The bottom ring 15 of the fixing frame 14 is then smoothly placed against the patient's skin surface to be treated, completing the positioning and protective enclosure of the treatment area.

[0038] The transmission chamber 13 houses a drive motor, which drives the drive gear 27 to rotate. The drive gear 27 meshes with the transmission gear 1701 on the extension rod 17, thereby synchronously moving the extension rod 17 and the laser treatment head 16 at its bottom up and down. This allows for flexible adjustment of the vertical distance between the laser treatment head 16 and the patient's skin. During the up-and-down movement of the extension rod 17, the limiting slide strip 19 on the rod always slides within the limiting groove 18. Relying on the guiding and limiting effect of both, the movement of the extension rod 17 and the laser treatment head 16 is ensured to be smooth and stable, without any tilting or jamming.

[0039] Before the laser treatment head 16 is activated, the baffle 22 inside the mounting bracket 14 remains extended, completely blocking the laser emission port of the laser treatment head 16 to prevent accidental laser output and avoid injury to the patient's skin. The distance sensor 47 installed at the end of the baffle 22 continuously measures the distance between the laser treatment head 16 and the patient's skin. Only when the distance sensor 47 detects that the distance between the laser treatment head 16 and the patient's skin surface is at a suitable treatment position will the subsequent mechanism operation be triggered.

[0040] The transmission chamber 25 houses a drive motor, which rotates the drive gear 33. The drive gear 33 meshes with and drives the rack 32 to move laterally, thereby causing the baffle 22 to gradually retract into the clamping plate 23. This prevents the baffle 22 from obstructing the emission port of the laser treatment head 16, ensuring that the laser can be emitted normally for cosmetic treatment. As the baffle 22 retracts and moves, the scraping part 24 at the bottom of the clamping plate 23 slides synchronously against the measuring end of the distance sensor 47, cleaning contaminants adhering to the probe surface to prevent dirt from obstructing the probe's sensing surface and affecting the accuracy of distance measurement.

[0041] As the baffle 22 retracts and the rack 32 moves into the transmission chamber 25, the end of the rack 32 presses against the arc-shaped block 34 and moves along the arc surface of the arc-shaped block 34, causing the arc-shaped block 34 to move vertically upward. Simultaneously, the arc-shaped block 34 drives the sliding rod 35 upward and compresses the spring 37, causing it to contract. At the same time, the sliding rod 35 pulls the pull rope 40 connected to its bottom end. The bent pipe 39 fixed to the inner wall of the isolation chamber 11 limits and guides the pull rope 40, constraining its direction and preventing it from shifting arbitrarily, thus ensuring stable power transmission. After being stressed, the pull rope 40 pulls the sliding rod 42 downward. The fixed plate 41 moves downward synchronously with the sliding rod 42, the spring 43 is stretched and undergoes elastic deformation, and the block 45 at the top of the sliding rod 42 moves downward, disengaging from the internal passage of the intake pipe 26. In the initial state, the block 45 is sealed inside the air inlet pipe 26, blocking the cooling medium from entering the laser treatment component 7. After the block 45 is removed, the air inlet pipe 26 is fully opened, and the cooling medium inside the cooling pipe 10 can be transported into the laser treatment component 7 through the air inlet pipe 26 and then discharged through the air outlet pipe 48, forming a circulating heat dissipation airflow to continuously cool and reduce the temperature of the laser treatment component 7 in the working state.

[0042] The regulating valve core 46 has a structure similar to a butterfly valve core. In the initial state, the regulating valve core 46 does not completely block the air inlet pipe 26, allowing the cooling medium to flow normally at a low flow rate. As the laser treatment head 16 and extension rod 17 move downward to adjust the treatment distance, the laser output power of the device increases accordingly, and the heat generated inside the laser treatment component 7 also increases simultaneously. While the drive gear 27 drives the extension rod 17 downward through the transmission gear 1701, it also drives the driven gear 28 to rotate. The driven gear 28 sequentially drives the first bevel gear 29 and the second bevel gear 30 to rotate. The second bevel gear 30 drives the rotating shaft 31 to rotate, and the rotating shaft 31 further drives the regulating valve core 46 to rotate, increasing the opening range of the regulating valve core 46. The flow rate of the cooling medium flowing into the laser treatment component 7 through the air inlet pipe 26 increases accordingly, matching the heat dissipation requirements under high-power operation and preventing the component from overheating and affecting the treatment effect and equipment lifespan.
