Description

Technical Field

[0001] This application relates to the technical field of semiconductor lasers, and in particular to a multi-channel composite laser therapy device. Background Technology

[0002] A multi-channel composite laser therapy device is an advanced medical device that integrates multiple lasers of different wavelengths and can work simultaneously or in shifts through multiple independent output ports to achieve synergistic therapeutic effects.

[0003] A dual-wavelength multi-channel laser acupuncture device, currently announced under CN205626462U, includes a control system, a drive power supply, a semiconductor laser module, an optical fiber coupler, an optical fiber channel, an optical fiber fixing head, and host computer software. The semiconductor laser module comprises multiple sets of 808nm and 635nm lasers, with one 635nm laser and one 808nm laser forming one set. The optical fiber coupler couples the two different wavelengths of laser light into a single optical fiber, resulting in one channel's output. The optical fiber channel uses an adjustable metal arm to adjust and fix the fiber, allowing for arbitrary control and adjustment of the effective working distance and working angle. The control system uses a central control chip to control the drive power supply. The host computer software transmits data to the control module via an RS232 serial port, controlling and displaying current, power, and temperature. The optical fiber fixing head secures the optical fiber to the irradiation target.

[0004] Regarding the aforementioned technologies, the fiber optic channel uses an adjustable metal arm to adjust and fix the fiber, which limits the length of the fiber optic channel to the length of the metal arm. This makes it difficult to extend the fiber optic channel and reach more distant affected areas, causing inconvenience for operators. Summary of the Invention

[0005] In order to extend the fiber optic channel and facilitate operation by the operator, this application provides a multi-channel composite laser therapy device.

[0006] The multi-channel composite laser therapy device provided in this application adopts the following technical solution:

[0007] A multi-channel composite laser therapy device, comprising:

[0008] A main unit housing, wherein a semiconductor laser is installed inside the main unit housing, and multiple support arms are fixedly connected to one side of the main unit housing. Each support arm is equipped with a treatment handle, and each treatment handle is connected to an optical fiber path. All of the multiple optical fiber paths are connected to the semiconductor laser.

[0009] The cable management component includes multiple cable management roller groups, which are slidably connected inside the main unit housing. The multiple optical fiber paths are wound one-to-one around the multiple cable management roller groups.

[0010] A synchronizing element is installed between the plurality of said yarn-training roller groups to enable each group of said yarn-training roller groups to move synchronously.

[0011] A reset element is connected to the synchronization element, and the reset element synchronously drives the cable management rollers to move away from each other through the synchronization element so as to keep the optical fiber path taut.

[0012] The main unit chassis is equipped with several heat dissipation fin assemblies to dissipate heat from the main unit chassis.

[0013] The heat dissipation blade assembly includes several parallel blade rods and heat dissipation blades connected to each blade rod in a one-to-one correspondence, and adjacent heat dissipation blades can be tangent to each other during rotation.

[0014] By adopting the above technical solution, when the operator operates the treatment handle, the operator removes the treatment handle from the support arm, and then holds the treatment handle to pull the optical fiber path, so that the optical fiber path passes out from the main unit box, and the extended optical fiber path makes it easier for the operator to hold the treatment handle to move to a more distant affected area, and makes it easier for the operator to hold the treatment handle to operate.

[0015] As the optical fiber path exits from the main unit, multiple cable management rollers wound around the exiting optical fiber move closer to each other, shortening the optical path within the main unit. Simultaneously, the synchronization mechanism causes multiple cable management rollers wound around other optical fiber paths to move closer to each other synchronously. This allows the optical fiber path to exit the main unit more easily when the operator controls one treatment handle for treatment and then controls another treatment handle for treatment, facilitating the operator's operation.

[0016] When the operator finishes using the equipment, the reset component drives the synchronization component to move the cable management rollers away from each other, thereby bringing the optical fiber path that has come out of the main unit back into the main unit, making the optical fiber path more organized and easier to reuse.

[0017] By utilizing the cable management components, synchronization components, and reset components, the treatment handle can smoothly pass through the main unit during operation, extending the fiber optic path and making it easier for the operator to move the treatment handle to a more distant affected area, thus facilitating the operation.

[0018] Optionally, the cable management component further includes a cable management box, which is fixedly connected inside the main unit chassis. The synchronization component is installed inside the cable management box. Two sets of cable management rollers are provided, and the two sets of cable management rollers are symmetrically arranged about the synchronization component. Each set of cable management rollers includes several cable management rollers arranged in an "S" shape. All cable management rollers are installed on the synchronization component. Two optical fiber paths are provided, and the two optical fiber paths are wound one-to-one around the same set of cable management rollers.

[0019] By adopting the above technical solution, the "S"-shaped arrangement of the fiber management rollers reduces stress concentration and micro-bending loss in the optical fiber, helping to maintain laser transmission efficiency. Simultaneously, the two fiber paths are independently installed on their respective fiber management rollers. During the resetting or stretching process, the two fiber paths will not interfere with each other, thus ensuring smooth stretching and resetting of the fiber paths. Furthermore, the symmetrical arrangement of the fiber management roller assembly about the synchronization element facilitates the synchronization and stable control of the roller assembly's movement.

[0020] Optionally, the synchronizing element includes multiple main synchronizing racks, multiple secondary synchronizing racks, and multiple synchronizing gears. The cable management roller is correspondingly mounted on the main synchronizing rack or the secondary synchronizing rack. The main synchronizing rack and the secondary synchronizing rack are slidably connected within the cable management box, and the main synchronizing rack and the secondary synchronizing rack are arranged alternately in sequence. The synchronizing gear is rotatably connected within the cable management box, and the synchronizing gear is located between each of the main synchronizing rack and the secondary synchronizing rack. One side of the synchronizing gear meshes with the main synchronizing rack, and the other side meshes with the secondary synchronizing rack. One side of the resetting element is connected to the main synchronizing rack, and the other side is connected to the secondary synchronizing rack.

[0021] By adopting the above technical solution, when the operator operates the treatment handle to pull the optical fiber path, the uppermost thread-guiding roller is forced to move towards the middle. The movement of the thread-guiding roller drives the main synchronous rack to move towards the middle. The movement of the main synchronous rack towards the middle drives the secondary synchronous rack to move towards the middle through the synchronous gear. This shortens the distance between the thread-guiding rollers on the main synchronous rack and the secondary synchronous rack, thus shortening the optical fiber path stored in the main unit box and making it easier for the optical fiber path to pass out of the main unit box.

[0022] By using multiple main synchronous racks and multiple secondary synchronous racks arranged alternately, and then using synchronous gears to drive adjacent main synchronous racks and secondary synchronous racks to move synchronously, the movement of the fiber optic roller group is ensured to be consistent. This ensures the synchronous application of the fiber optic path tension force, which can reduce the damage caused by the pulling of multiple parts of the fiber optic path and improve the service life of the fiber optic path.

[0023] Optionally, the reset component includes a reset pressure plate and a reset rope. The reset pressure plate is located at the bottom of the cable management box. Two reset ropes are provided, and both reset ropes are connected to the reset pressure plate. The synchronization component is located between the two reset ropes, and one of the reset ropes is connected to the main synchronization rack, while the other reset rope is connected to the secondary synchronization rack.

[0024] By adopting the above technical solution, when the treatment handle is used up, the reset plate moves downward by its own gravity. When the reset plate moves downward, it pulls the main synchronous rack and the secondary synchronous rack to move to both sides through the reset rope, so that the main synchronous rack and the secondary synchronous rack move away from each other, thereby causing the cable management rollers located on the main synchronous rack and the secondary synchronous rack to move away from each other, thereby allowing the optical fiber path extending out of the main unit to be stored in the main unit.

[0025] At the same time, the combination of the reset plate and the reset rope can keep the optical fiber path inside the main unit chassis taut at all times, thereby preventing the optical fiber path from getting tangled inside the main unit chassis.

[0026] Optionally, a balance block is provided at the bottom of the main unit chassis, and a balance rope is connected to the balance block. The balance rope passes through the top of the cable management box and is fixedly connected to the reset pressure plate at the bottom of the cable management box.

[0027] By adopting the above technical solution, when the operator operates the treatment handle to pull the optical fiber path, the main synchronization rack and the secondary synchronization rack move closer to each other. As a result, the main synchronization rack and the secondary synchronization rack pull the reset rope and drive the reset pressure plate to move upward towards the main unit box, thereby causing the center of gravity of the main unit box to shift upward, making the center of gravity of the main unit box easily unstable during operation.

[0028] Therefore, a balance block is installed at the bottom of the main unit chassis. When the reset plate moves upward, the reset plate drives the balance block downward through the balance rope, thereby reducing the change in the center of gravity of the main unit chassis and making the main unit chassis more stable during operation.

[0029] Optionally, a linkage is installed between the heat dissipation blade assembly and the balance rope, so that the heat dissipation blade assembly is driven to open or close through the linkage when the balance rope moves.

[0030] By adopting the above technical solution, the semiconductor laser will generate a lot of heat when it is working. Therefore, when the operator operates the treatment handle, the semiconductor laser will work. The operator holds the treatment handle and pulls the optical fiber path. The optical fiber path will cause the main synchronization rack and the secondary synchronization rack to move closer to each other. The main synchronization rack and the secondary synchronization rack move closer to each other and drive the reset plate to move upward through the reset rope. When the reset plate moves upward, it will drive the balance rope to move downward. The downward movement of the balance rope will drive the heat dissipation blade assembly to open through the linkage to dissipate heat from the semiconductor laser.

[0031] After the operator finishes the operation, the semiconductor laser stops working, the fiber optic path is reset, the main synchronization rack and the secondary synchronization rack move away from each other, the reset plate moves downward, the downward movement of the reset plate drives the balance rope to move upward, and the upward movement of the balance rope drives the heat dissipation blade assembly to close, preventing external dust from entering the main unit.

[0032] Optionally, each blade is fixedly connected to an extension lug, and a drive rod is rotatably connected to the end of the extension lug away from the blade, the drive rod being connected to the linkage.

[0033] By adopting the above technical solution, the linkage controls the movement of the drive rod, which in turn controls the rotation of all the blades via the extended lug, thereby synchronously controlling the rotation of all the heat dissipation blades. Simultaneously, the tangency of adjacent heat dissipation blades ensures a good seal when closed, preventing dust from entering.

[0034] Optionally, the linkage includes a linkage rod, a drive block, and an abutment block. One end of the linkage rod is fixedly connected to the drive rod, and the other end is fixedly connected to the drive block. The drive block has a waist-shaped hole, and the balance rope passes through the waist-shaped hole. The abutment block is fixedly connected to the balance rope, and the balance block abuts against the bottom of the drive block.

[0035] By adopting the above technical solution, when the semiconductor laser is working, the balance rope moves downward, causing the abutment block to disengage from the drive block. Under the action of gravity, the drive block drives the linkage rod to move downward. The downward movement of the linkage rod drives the drive rod to move downward. The drive rod uses the extension lug to synchronously control the rotation of all the blade rods, thereby controlling all the heat dissipation blades to be in the open state.

[0036] When the semiconductor laser stops working, the balance rope moves upward, causing the abutment block to contact the drive block. This causes the drive block to move upward, and the linkage rod moves upward, driving the drive rod upward. The drive rod, using its extension lugs, synchronously controls all the blades to rotate in the opposite direction, thus keeping all the heat dissipation blades in the closed state.

[0037] Optionally, a fixed base and a compression base are fixedly connected to the main chassis, a compression block is slidably connected between the fixed base and the compression base, a compression spring is installed between the compression block and the fixed base, the compression spring drives the compression block to move toward the compression base, and the optical fiber path is located between the compression block and the compression base.

[0038] By adopting the above technical solution, when the operator holds the treatment handle and pulls the optical fiber path, the squeezing block, driven by the squeezing spring, squeezes the optical fiber path. The constant pressure of the squeezing spring fixes the optical fiber path between the squeezing block and the squeezing seat, preventing the optical fiber path from resetting during the operation of the treatment handle, thus making it easier for the operator to hold the treatment handle.

[0039] Optionally, multiple mounting bases are provided, and the mounting bases protrude from the main unit chassis, with handles fixedly connected between the multiple mounting bases.

[0040] By adopting the above technical solution, the handle is designed to facilitate gripping of the host chassis, thereby making it easier to move the host chassis.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] Through the cooperation of the main unit, semiconductor laser, support arm, treatment handle, fiber optic path, filament roller assembly, synchronization component, and reset component, the treatment handle can smoothly pass through the main unit during operation, extending the fiber optic path. This makes it easier for the operator to move the treatment handle to a more distant affected area and facilitates operation. At the same time, the reset component drives the synchronization component to drive the filament rollers away from each other, thereby retracting the fiber optic path from the main unit back into the main unit, making the fiber optic path more regular and easy to reuse.

[0043] By coordinating the cable management rollers, fiber optic path, main synchronous rack, secondary synchronous rack, and synchronous gear, the cable management roller assembly moves in unison, ensuring the synchronous application of tension force in the fiber optic path. This reduces damage caused by pulling on multiple parts of the fiber optic path and extends its service life.

[0044] By coordinating the heat dissipation blade assembly, blade rod, heat dissipation blade, extension ear, drive rod, linkage component, linkage rod, drive block, and abutment block, when the operator starts the semiconductor laser, the operator holds the treatment handle and pulls the fiber optic path, thereby driving the balance rope to move. Therefore, the linkage component is used to control the movement of the balance rope to open the heat dissipation blade assembly, simplifying the operation of the semiconductor laser heat dissipation.

[0052] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0053] This application discloses a multi-channel composite laser therapy device.

[0054] Reference Figure 1-3 A multi-channel composite laser therapy device includes a main unit 1, a cable management component 2, a synchronization component 3, and a reset component 4. A semiconductor laser 11 is installed inside the main unit 1, and multiple support arms 12 are fixedly connected to one side of the main unit 1. Each support arm 12 has a treatment handle 13 inserted into it, and each treatment handle 13 is connected to an optical fiber path 14. All optical fiber paths 14 are connected to the semiconductor laser 11. The cable management component 2 includes multiple cable management roller groups 21, which are slidably connected inside the main unit 1. Multiple optical fiber paths 14 are wound one-to-one around the multiple cable management roller groups 21. The synchronization component 3 is installed between the multiple cable management roller groups 21 to ensure synchronous movement of each cable management roller group 21. The reset component 4 is connected to the synchronization component 3, and the reset component 4 synchronously drives the cable management roller groups 21 away from each other through the synchronization component 3 to keep the optical fiber paths 14 taut. By utilizing the cooperation of the cable management component 2, the synchronization component 3, and the reset component 4, the treatment handle 13 can smoothly pass through the main unit 1 during operation, allowing the fiber optic path 14 to extend, thus making it easier for the operator to hold the treatment handle 13 and move it to a more distant affected area, and making it easier for the operator to hold the treatment handle 13 for operation.

[0055] The bottom of the main unit 1 is equipped with a caster wheel 15 with a self-locking function, which facilitates the movement of the main unit 1. The top of the main unit 1 is fixedly connected to a fixed base 16 and a pressing base 17. A pressing block 18 is slidably connected between the fixed base 16 and the pressing base 17. A pressing spring 19 is installed between the pressing block 18 and the fixed base 16. The pressing spring 19 drives the pressing block 18 to move toward the pressing base 17. The optical fiber path 14 is located between the pressing block 18 and the pressing base 17. The pressing of the pressing block 18 and the pressing base 17 is used to position the optical fiber path 14.

[0056] When the operator holds the treatment handle 13 and pulls the optical fiber path 14, the compression block 18, driven by the compression spring 19, compresses the optical fiber path 14. The constant pressure of the compression spring 19 fixes the optical fiber path 14 between the compression block 18 and the compression seat 17, preventing the optical fiber path 14 from resetting during the operation of the treatment handle 13, thus making it easier for the operator to hold the treatment handle 13 for operation.

[0057] In this embodiment, a reset protrusion 181 is also fixedly connected to the compression block 18. When the optical fiber path 14 needs to be reset, the reset protrusion 181 is moved to compress the compression spring 19, thereby allowing the optical fiber path 14 to be released from the compression of the compression block 18 and the compression seat 17, so that the optical fiber path 14 can be reset smoothly.

[0058] In this embodiment, the semiconductor laser 11 has two independent laser output terminals, one a 755nm laser and the other a 595nm laser, which emit lasers independently. Each of the two independent laser output terminals is connected to one of two optical fiber paths 14. The 755nm laser in this embodiment is mainly used for hair removal and brown pigmentation removal in individuals with light skin, while the 595nm laser is used to treat red vascular diseases (such as port-wine stains and telangiectasia). Therefore, this embodiment has two mounting bases 16, which protrude from the main unit housing 1, and a handle 5 is fixedly connected between the two mounting bases 16.

[0059] In other embodiments, the semiconductor laser 11 may also be configured with 4 or 6 output terminals, and a number of optical fiber channels 14 corresponding to the number of output terminals of the semiconductor laser 11 are connected to it. Then, a fixed seat 16 corresponding to the number of optical fiber channels 14 is set, and a handle 5 is set between the two fixed seats 16.

[0060] Since the main unit 1 in this embodiment is moved by casters 15, and the handle 5 is designed to facilitate gripping of the main unit 1, the main unit 1 can be moved stably by gripping the handle 5 when it is necessary to move the main unit 1.

[0061] The cable management component 2 includes a cable management box 22, which is fixedly connected inside the main unit box 1. The synchronization component 3 is installed inside the cable management box 22. In this embodiment, two sets of cable management roller groups 21 are provided. The two sets of cable management roller groups 21 are symmetrically arranged about the synchronization component 3. By using the symmetrical arrangement of the cable management roller groups 21 about the synchronization component 3, the synchronization component 3 can easily and stably control the movement of the cable management roller groups 21.

[0062] Each fiber management roller group 21 includes several fiber management rollers 211 arranged in an "S" shape. The "S"-shaped arrangement of the fiber management rollers 211 reduces stress concentration and micro-bending loss in the optical fiber, which helps maintain laser transmission efficiency.

[0063] The fiber optic rollers 211 are all mounted on the synchronizing element 3. Two fiber optic paths 14 are provided, and each path is wound one-to-one around the same set of fiber optic rollers 211. The two fiber optic paths 14 are independently mounted on their respective rollers 211. During resetting or stretching, the two fiber optic paths 14 will not interfere with each other, thus ensuring smooth stretching and resetting of the fiber optic paths 14.

[0064] Reference Figure 3 and 4 In this embodiment, the synchronization component 3 includes multiple main synchronization racks 31, multiple secondary synchronization racks 32, and multiple synchronization gears 33. The thread-reaming rollers 211 are installed on the main synchronization racks 31 or secondary synchronization racks 32 respectively. Only one thread-reaming roller 211 located on the same thread-reaming roller group 21 is installed on each main synchronization rack 31 or secondary synchronization rack 32. That is, two thread-reaming rollers 211 located on different thread-reaming roller groups 21 are symmetrically installed on the main synchronization racks 31 or secondary synchronization racks 32 about the main synchronization racks 31 or secondary synchronization racks 32.

[0065] Both the main synchronizing rack 31 and the secondary synchronizing rack 32 are slidably connected inside the cable management box 22, and the main synchronizing rack 31 and the secondary synchronizing rack 32 are arranged alternately in sequence. The synchronizing gear 33 is rotatably connected inside the cable management box 22, and the synchronizing gear 33 is located between each main synchronizing rack 31 and the secondary synchronizing rack 32. One side of the synchronizing gear 33 meshes with the main synchronizing rack 31, and the other side meshes with the secondary synchronizing rack 32. One side of the reset member 4 is connected to the main synchronizing rack 31, and the other side is connected to the secondary synchronizing rack 32.

[0066] When the operator operates the treatment handle 13 to pull the optical fiber path 14, the uppermost thread-guiding roller 211 is forced to move towards the center. The movement of the thread-guiding roller 211 drives the main synchronous rack 31 to move towards the center. The movement of the main synchronous rack 31 towards the center drives the secondary synchronous rack 32 to move towards the center through the synchronous gear 33. This shortens the distance between the thread-guiding rollers 211 on the main synchronous rack 31 and the secondary synchronous rack 32, thus shortening the optical fiber path 14 stored in the main unit box 1, making it easier for the optical fiber path 14 to pass out of the main unit box 1.

[0067] By using multiple main synchronous racks 31 and multiple secondary synchronous racks 32 arranged alternately, and then using synchronous gears 33 to drive adjacent main synchronous racks 31 and secondary synchronous racks 32 to move synchronously, the movement of the fiber optic roller group 21 is consistent, ensuring the synchronous application of the tension of the fiber optic path 14. This can reduce the damage caused by the pulling of multiple parts of the fiber optic path 14 and improve the service life of the fiber optic path 14.

[0068] In this embodiment, the reset component 4 includes a reset pressure plate 41 and a reset rope 42. In other embodiments, the reset component 4 may also use a torsion spring or a tension spring for reset. The reset pressure plate 41 is located at the bottom of the cable management box 22. Two reset ropes 42 are provided, and both reset ropes 42 are connected to the reset pressure plate 41. The synchronization component 3 is located between the two reset ropes 42, with one reset rope 42 connected to the main synchronization rack 31 and the other reset rope 42 connected to the secondary synchronization rack 32. The weight of the reset pressure plate 41 drives the main synchronization rack 31 and the secondary synchronization rack 32 to move via the reset ropes 42, thereby completing the reset of the optical fiber path 14.

[0069] After the treatment handle 13 is used up, the reset plate 41 moves downward by its own weight. When the reset plate 41 moves downward, it pulls the main synchronous rack 31 and the secondary synchronous rack 32 to the sides through the reset rope 42, so that the main synchronous rack 31 and the secondary synchronous rack 32 move away from each other, thereby causing the cable management rollers 211 located on the main synchronous rack 31 and the secondary synchronous rack 32 to move away from each other, so that the optical fiber path 14 extending out of the main unit box 1 is stored in the main unit box 1.

[0070] Meanwhile, the cooperation of the reset plate 41 and the reset rope 42 can keep the optical fiber path 14 located in the main unit box 1 taut at all times, thereby preventing the optical fiber path 14 from getting tangled in the main unit box 1.

[0071] When the operator operates the treatment handle 13 to pull the fiber optic path 14, the main synchronization rack 31 and the secondary synchronization rack 32 move closer to each other. As a result, the main synchronization rack 31 and the secondary synchronization rack 32 pull the reset rope 42, causing the reset pressure plate 41 to move upward toward the main unit box 1. This causes the center of gravity of the main unit box 1 to shift upward, making the center of gravity of the main unit box 1 easily unstable during operation.

[0072] Therefore, in this embodiment, a balance block 6 is also provided at the bottom of the main unit chassis 1. A balance rope 61 is connected to the balance block 6. The balance rope 61 passes through the top of the cable management box 22 and is fixedly connected to the reset pressure plate 41 at the bottom of the cable management box 22. When the reset pressure plate 41 moves upward, the reset pressure plate 41 drives the balance block 6 to move downward through the balance rope 61, thereby reducing the change in the center of gravity of the main unit chassis 1, and thus making the main unit chassis 1 more stable during operation.

[0073] Reference Figure 3 and Figure 5 The semiconductor laser 11 generates a lot of heat during operation. In order to facilitate heat dissipation during the operation of the semiconductor laser 11, a number of heat dissipation blade groups 7 are installed on the main unit 1. In this embodiment, the heat dissipation blade groups 7 are arranged on both sides of the semiconductor laser 11. A linkage 8 is installed between the heat dissipation blade groups 7 and the balance rope 61 so that the heat dissipation blade groups 7 are opened or closed through the linkage 8 when the balance rope 61 moves.

[0074] The movement of the balance rope 61 is related to the operator's control of the semiconductor laser 11. When the operator turns on the semiconductor laser 11, the operator will hold the treatment handle 13 and pull the fiber optic path 14, thereby driving the balance rope 61 to move. Therefore, the movement of the balance rope 61 is controlled by the linkage 8 to open the heat dissipation blade group 7, which simplifies the heat dissipation operation of the semiconductor laser 11 during operation.

[0075] When the operator operates the treatment handle 13, the semiconductor laser 11 works. Holding the treatment handle 13 pulls the fiber optic path 14, which causes the main synchronization rack 31 and the secondary synchronization rack 32 to move closer to each other. The main synchronization rack 31 and the secondary synchronization rack 32 move closer to each other, which in turn causes the reset pressure plate 41 to move upward through the reset rope 42. When the reset pressure plate 41 moves upward, it causes the balance rope 61 to move downward. The downward movement of the balance rope 61 causes the heat dissipation blade group 7 to open through the linkage 8 to dissipate heat from the semiconductor laser 11.

[0076] After the operator finishes the operation, the semiconductor laser 11 stops working, the fiber optic path 14 is reset, the main synchronous rack 31 and the secondary synchronous rack 32 move away from each other, the reset plate 41 moves downward, the reset plate 41 moves downward, driving the balance rope 61 to move upward, the balance rope 61 moves upward through the linkage 8, driving the heat dissipation blade group 7 to close, preventing external dust from entering the main unit 1.

[0077] The heat dissipation blade assembly 7 includes several parallel blade rods 71 ​​and heat dissipation blades 72 connected one-to-one with the blade rods 71. The adjacent heat dissipation blades 72 can be tangent to each other during rotation. The tangency of the adjacent heat dissipation blades 72 ensures good sealing when closed, preventing dust from entering.

[0078] Each blade 71 is fixedly connected to an extension lug 73. The end of the extension lug 73 away from the blade 71 is rotatably connected to a drive rod 74, which is connected to the linkage 8. The linkage 8 controls the movement of the drive rod 74, which in turn controls the rotation of all blades 71 through the extension lugs 73, thereby synchronously controlling the rotation of all heat dissipation blades 72.

[0079] The linkage component 8 includes a linkage rod 81, a drive block 82, and an abutment block 83. One end of the linkage rod 81 is fixedly connected to the drive rod 74, and the other end is fixedly connected to the drive block 82. The drive block 82 has a waist-shaped hole 84, and the balance rope 61 passes through the waist-shaped hole 84. The abutment block 83 is fixedly connected to the balance rope 61, and the balance block 83 abuts against the bottom of the drive block 82.

[0080] When the semiconductor laser 11 is working, the balance rope 61 moves downward, causing the abutment block 83 to disengage from the drive block 82. Under the action of gravity, the drive block 82 drives the linkage rod 81 to move downward. The downward movement of the linkage rod 81 drives the drive rod 74 to move downward. The drive rod 74 uses the extension lug 73 to synchronously control the rotation of all the blade rods 71, thereby controlling all the heat dissipation blades 72 to be in the open state.

[0081] When the semiconductor laser 11 stops working, the balance rope 61 moves upward, causing the abutment block 83 to abut against the drive block 82. Under the abutment of the abutment block 83, the drive block 82 moves upward, and the linkage rod 81 moves upward, driving the drive rod 74 to move upward. The drive rod 74 uses the extension lug 73 to synchronously control all the blade rods 71 ​​to rotate in the opposite direction, thereby controlling all the heat dissipation blades 72 to be in the closed state.

[0082] The implementation principle of a multi-channel composite laser therapy device according to an embodiment of this application is as follows: When the operator operates the treatment handle 13, the operator removes the treatment handle 13 from the support arm 12, and then holds the treatment handle 13 to pull the optical fiber path 14, so that the optical fiber path 14 passes through the main unit box 1, causing the optical fiber path 14 to extend out of the main unit box 1. After the optical fiber path 14 extends to a suitable distance, the compression block 18 and the compression seat 17 compress and position the optical fiber path 14 to prevent the optical fiber path 14 from resetting during the operation of the operator holding the treatment handle 13. The extended optical fiber path 14 makes it easier for the operator to move the treatment handle 13 to a more distant affected area, and makes it easier for the operator to operate the treatment handle 13.

[0083] When the fiber optic path 14 exits from the main unit chassis 1, the uppermost cable management roller 211 is forced to move towards the center. The movement of the cable management roller 211 drives the main synchronous rack 31 to move towards the center. The movement of the main synchronous rack 31 towards the center drives the secondary synchronous rack 32 to move towards the center through the synchronous gear 33. This shortens the distance between the cable management rollers 211 on the main synchronous rack 31 and the secondary synchronous rack 32, thus shortening the fiber optic path 14 stored in the main unit chassis 1 and increasing the length of the fiber optic path 14 exiting the main unit chassis 1.

[0084] By using multiple main synchronous racks 31 and multiple secondary synchronous racks 32 arranged alternately, and then using synchronous gears 33 to drive adjacent main synchronous racks 31 and synchronous racks to move synchronously, the movement of the fiber optic roller group 21 is ensured to be consistent, and the tension of the fiber optic path 14 is ensured to be applied synchronously. This can reduce the damage caused by the pulling of multiple parts of the fiber optic path 14 and improve the service life of the fiber optic path 14.

[0085] When the main synchronizing rack 31 and the secondary synchronizing rack 32 approach each other, the main synchronizing rack 31 and the secondary synchronizing rack 32 pull the reset rope 42, causing the reset pressure plate 41 to move upward toward the main unit 1. When the reset pressure plate 41 moves upward, it causes the reset pressure plate 41 to drive the balance block 6 downward through the balance rope 61, so that the balance block 6 reduces the change in the center of gravity of the main unit 1, thereby making the main unit 1 more stable during operation.

[0086] As the balance block 6 moves downward, the balance rope 61 also moves downward, causing the abutment block 83 to disengage from the drive block 82. Under the influence of gravity, the drive block 82 drives the linkage rod 81 to move downward. The downward movement of the linkage rod 81 drives the drive rod 74 to move downward. The drive rod 74 uses the extension lug 73 to synchronously control the rotation of all the blade rods 71, thereby controlling all the heat dissipation blades 72 to be in the open state. This facilitates the heat dissipation blades 72 to dissipate heat from the semiconductor laser 11.

[0087] When the treatment handle 13 is finished, the reset protrusion 181 is moved to compress the compression spring 19, thereby causing the optical fiber path 14 to be released from the compression of the compression block 18 and the compression seat 17. The reset plate 41 moves downward by its own weight. When the reset plate 41 moves downward, it pulls the main synchronous rack 31 and the secondary synchronous rack 32 to move to both sides through the reset rope 42, so that the main synchronous rack 31 and the secondary synchronous rack 32 move away from each other, thereby causing the cable management rollers 211 located on the main synchronous rack 31 and the secondary synchronous rack 32 to move away from each other, and thus allowing the optical fiber path 14 extending out of the main unit box 1 to be stored in the main unit box 1.

[0088] When the reset plate 41 moves downward, the balance rope 61 moves upward, causing the abutment block 83 to abut against the drive block 82. Under the abutment of the abutment block 83, the drive block 82 moves upward. The linkage rod 81 moves upward, driving the drive rod 74 to move upward. The drive rod 74 uses the extension ear 73 to synchronously control all the blade rods 71 ​​to rotate in the opposite direction, thereby controlling all the heat dissipation blades 72 to be in the closed state, preventing dust from entering the main unit case 1.

[0089] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
