[0029] Example 1:

[0030] like Figures 1-5 As shown, this embodiment provides an ultraviolet light device for corneal crosslinking, including: a lamp holder 10, a first lens barrel 40, and a light source structure. The lamp holder 10 has at least two through holes arranged in an array along its thickness direction. Multiple first lens barrels 40 are provided, each of which is installed in one of the through holes. A light source adjustment structure is provided inside the first lens barrel 40. The light source structure is located on the side of the lamp holder 10 away from the first lens barrel 40 along its thickness direction. The ultraviolet light emitted by the light source structure passes through the light source adjustment structure inside the first lens barrel 40 and is adjusted into an ultraviolet beam that can be transmitted through an optical fiber.

[0031] In some embodiments, the lamp holder 10 serves as the main structure of the ultraviolet light device. The lamp holder 10 is adapted to be connected to other devices (other devices may be mounting bases or movable bases, etc., which are not limited here). The lamp holder 10 has through holes inside. The circuit board 20 is disposed on one side of the lamp holder 10 in the thickness direction. The circuit board 20 provides electrical connection and control for the electronic components in the ultraviolet light device. The first output structure has a plurality of first optical fibers 33 and a second optical fiber 32. The plurality of first optical fibers 33 are respectively connected to the output ends of a plurality of first lens barrels 40. The second optical fiber 32 is used to combine the ultraviolet light input from the plurality of first optical fibers 33 and output it. The ultraviolet light emitted by the light source structure passes through the first lens barrel 40 in sequence and is input to the first output structure. The first output structure has a plurality of first optical fibers 33. The plurality of first optical fibers 33 and the second optical fiber 32 are used to combine and output the ultraviolet light generated by the light source structure. The array of a plurality of first lens barrels 40 is disposed on the side of the lamp holder 10 close to the light source structure in the thickness direction. The first output structure is used to guide the light to the patient's cornea.

[0032] It is understood that the light source adjustment structure includes a first lens 41, a second lens 42, a third lens 43, and a fixing block 44. The fixing block 44 is fixedly disposed on the inner surface of the first lens barrel 40 at the end away from the light source structure. The third lens 43 is fixedly disposed on the fixing block 44. The first lens 41 is disposed on the side of the third lens 43 away from the light source structure. The second lens 42 is disposed between the third lens 43 and the first lens 41. The center lines of the first lens 41, the second lens 42, the third lens 43, and the first lens barrel 40 coincide.

[0033] It is worth mentioning that in this application, the light source adjustment structure is arranged within the first lens barrel 40 through a combination of a first lens 41, a second lens 42, a third lens 43, and a fixing block 44, forming a compact and efficient optical control unit. The third lens 43 is fixed at the end furthest from the light source structure, i.e., arranged on the fixing block 44, meaning it is located at the exit side of the entire optical path, playing a role in final correction and convergence. The first lens 41 is close to the starting end of the structure and is the first to receive the diverging light emitted from the ultraviolet lamp source 31. Its main function is to initially converge the light, reduce the divergence angle, and optimize the incident path, avoiding ineffective reflection of light within the lens barrel 40. The second lens 42, located between the first lens 41 and the third lens 43, plays a crucial role in further shaping the beam, ensuring that it maintains the quality and directionality of the light spot when traversing different media and transmission paths, and optimizing the coupling efficiency with the first optical fiber 33. The precise collinearity of the center points of the three lenses makes the entire optical system easy to assemble mechanically, while ensuring optical axis consistency, thereby effectively reducing common optical errors such as spherical aberration, astigmatism, and off-axis deviation. In clinical applications, this multi-lens synergistic optical path design enables the ultraviolet beam to possess higher directional consistency and energy stability, allowing for precise focusing on the corneal lesion and improving the uniformity and stability of the treatment light intensity. The main technical effect of this step is to achieve collimation and shaping of the ultraviolet beam, significantly improving light energy utilization and output consistency, and providing a high-quality light source guarantee for subsequent fiber optic transmission and lesion localization irradiation.

[0034] According to some embodiments of the present invention, the light source structure includes a circuit board 20 and an ultraviolet lamp source 31. The circuit board 20 is fixedly disposed on the lamp holder 10, and a plurality of ultraviolet lamp sources 31 are arranged in an array on the circuit board 20. Each ultraviolet lamp source 31 corresponds to one of the first lens barrels 40.

[0035] In some embodiments, the light source structure consists of a circuit board 20 and multiple ultraviolet lamp sources 31, forming a highly integrated and modular ultraviolet light emitting unit. The circuit board 20, serving as the core control and power supply platform, is fixedly mounted on the lamp holder 10. Its stable mechanical connection not only ensures the reliability of the electrical connection but also facilitates the assembly and maintenance of the overall device. Multiple ultraviolet lamp sources 31 are mounted in an array on the circuit board 20. This arrangement ensures that each ultraviolet lamp source 31 is precisely aligned with a corresponding first lens tube 40, thereby ensuring that each emitted ultraviolet light beam accurately enters its dedicated optical path. This one-to-one correspondence significantly reduces light energy deviation and loss in the initial stage of transmission, improving optical path efficiency. It also facilitates beam shaping through subsequent adjustment using the first lens 41, second lens 42, and third lens 43. More importantly, the array design facilitates multi-point synchronous irradiation, allowing the number of beams to be expanded according to actual treatment needs, enabling simultaneous treatment of multiple lesions and improving treatment efficiency and flexibility.

[0036] This step enables the ultraviolet light device to have high integration, excellent optical path matching accuracy and good scalability, reduces light energy loss caused by lamp source and optical path coupling errors in traditional systems, and reduces manufacturing complexity and cost, effectively supporting the miniaturization and lightweight design goals of the entire device.

[0037] According to some embodiments of the present invention, each of the first lens tubes 40 is respectively covered on its corresponding ultraviolet lamp source 31, and the ultraviolet beam output by the first lens tube 40 is parallel to its center line.

[0038] Understandably, each first lens tube 40 is precisely positioned over its corresponding ultraviolet lamp source 31, forming a closed, directional light transmission initiation structure. This positioning method not only provides physical shielding to prevent ultraviolet light leakage from harming the surrounding environment and operators, but more importantly, it ensures the collimation between the light source and the lens tube through mechanical fixing, ensuring that the ultraviolet beam output from the first lens tube 40 remains strictly parallel to its centerline. This design reduces the negative impact of primary divergence on subsequent optical systems and effectively avoids problems such as beam shift and focusing instability. In optical principles, a beam not parallel to the optical axis leads to aberrations and energy loss; therefore, this parallel optical axis design of the structure has very high practical value.

[0039] This step achieves consistency and stability of the light transmission path through dual mechanical and optical alignment, providing standardized input conditions for subsequent beam shaping and fiber coupling, thereby improving the overall system's light transmission efficiency and treatment accuracy, while also simplifying the assembly process and the complexity of subsequent maintenance and debugging.

[0040] According to some embodiments of the present invention, the corneal crosslinking ultraviolet light device further includes a heat dissipation component disposed on the side of the circuit board 20 away from the first lens barrel 40. The heat dissipation component includes a plurality of heat sinks 51, which are spaced apart along the width direction of the lamp holder 10. At least some of the heat sinks 51 are adapted to contact the circuit board 20 to dissipate heat from the circuit board 20.

[0041] In some embodiments, the heat dissipation component includes a plurality of heat sinks 51, each of which is adapted to conduct heat by directly contacting the circuit board 20, thereby dissipating heat from the circuit board 20. The plurality of heat sinks 51 are spaced apart along the width direction of the lamp holder 10 to increase the heat dissipation area and improve the heat dissipation efficiency of the circuit board 20.

[0042] A bracket 52 is connected to one end of multiple heat sinks 51 away from the circuit board 20. The bracket 52 is used to fix and support the heat sinks 51 and ensure stable contact between the multiple heat sinks 51 and the circuit board 20, thereby ensuring the heat dissipation effect on the circuit board 20.

[0043] In some embodiments, thermal grease is filled between the heat dissipation component and the circuit board 20. The thermal grease can fill the gap between the heat dissipation component and the circuit board 20, ensuring that the heat dissipation component and the circuit board 20 can be in direct contact from all directions, increasing the heat dissipation area and improving the heat dissipation efficiency of the circuit board 20.

[0044] According to some embodiments of the present invention, a bracket 52 is connected to one end of the plurality of heat sinks 51 away from the circuit board 20, and the bracket 52 is connected to the lamp holder 10.

[0045] The bracket 52 is equipped with multiple fans 53, and each of the multiple fans 53 corresponds to the ultraviolet lamp source 31.

[0046] Understandably, the fan 53 generates airflow by rotating, which more quickly removes the heat absorbed by the heat sink 51 and conducted to the air, forming thermal convection. Since multiple fans 53 are respectively facing multiple ultraviolet lamp sources 31, the airflow can directly act on the first mirror tube 40 and the ultraviolet lamp source 31 area, improving the heat dissipation efficiency of these areas and ensuring that the ultraviolet lamp source 31 operates at a suitable temperature.

[0047] Therefore, through the above-mentioned settings, this application can promptly remove the heat generated by the first lens tube 40 and the ultraviolet lamp source 31 during operation, ensuring that the ultraviolet lamp source 31 operates within a suitable temperature range, reducing light decay, and extending the service life of the ultraviolet lamp source 31.

[0048] According to some embodiments of the present invention, heat dissipation grooves 11 are respectively provided on both sides of the lamp holder 10 in the width direction. The heat dissipation grooves 11 are open in the width direction, and at least a portion of the circuit board 20 is directly opposite the heat dissipation grooves 11 in the thickness direction of the lamp holder 10.

[0049] It is understood that the heat dissipation component is adapted to function on the side of the circuit board 20 facing away from the lamp holder 10 to dissipate heat from the circuit board 20. The lamp holder 10 of this application also has heat dissipation grooves 11 on both sides in the width direction. The heat dissipation grooves 11 are open in the width direction, so that at least a portion of the side of the circuit board 20 facing the lamp holder 10 can be separated from the lamp holder 10 by the heat dissipation grooves 11, allowing the side of the circuit board 20 facing the lamp holder 10 to dissipate heat to the heat dissipation grooves 11, and finally dissipate it into the air.

[0050] Therefore, the heat dissipation effect of the circuit board 20 can be further enhanced by the heat dissipation slot 11, so as to effectively reduce the temperature of the circuit board 20 and the ultraviolet lamp source 31, reduce the failure and performance degradation of the ultraviolet light device caused by overheating, and improve the reliability and stability of the ultraviolet light device.

[0051] It is worth mentioning that the design of the heat dissipation groove 11 in this application effectively increases the heat dissipation area and air circulation channel without increasing the overall volume of the lamp holder 10, thus optimizing the structural design of the lamp holder 10.

[0052] According to some embodiments of the present invention, it further includes at least one infrared lamp source 62 and a second lens barrel 61. At least one infrared lamp source 62 is disposed on the side of the lamp holder 10 close to the light source structure in the thickness direction. The second lens barrel 61 is disposed corresponding to the infrared lamp source 62. The second lens barrel 61 is disposed on the other side of the lamp holder 10 in the thickness direction. The infrared light output by the infrared lamp source 62 passes through the second lens barrel 61 to output an infrared beam.

[0053] In some embodiments, the infrared light emitted by the infrared lamp source 62 is primarily used for positioning, helping doctors or operators determine the location of the treatment area or device. Specifically, by emitting infrared light, the infrared light can help doctors or operators more accurately locate the treatment area, ensuring that the ultraviolet light accurately irradiates the corneal area requiring treatment. Moreover, the positioning function of the infrared light makes the operation of the ultraviolet light device more convenient, allowing doctors or operators to more easily adjust the position and angle of the ultraviolet light device to adapt to different treatment needs.

[0054] It is worth mentioning that accurate positioning helps reduce the exposure of ultraviolet light to surrounding healthy tissues, thereby reducing the risks during treatment and improving the safety of treatment.

[0055] According to some embodiments of the present invention, the ultraviolet light device further includes an output structure, which has a plurality of first optical fibers 33 and a second optical fiber 32. The plurality of first optical fibers 33 are respectively connected to a plurality of first lens tubes 40. The second optical fiber 32 is used to combine the input light of the plurality of first optical fibers 33 and output it.

[0056] It is understood that this invention constructs a highly efficient ultraviolet light converging and output system using multiple first optical fibers 33 and one second optical fiber 32, playing a crucial role in receiving and integrating the light energy from various channels. Each first optical fiber 33 is connected to its corresponding first lens tube 40, ensuring that the light emitted from each different ultraviolet lamp source 31, after being shaped by the light source adjustment structure, can be efficiently and stably coupled into the optical fiber for transmission. The design of the first optical fiber 33 can be matched according to the size and numerical aperture of the output light spot of each lens tube to achieve optimal incident coupling efficiency and maximize the preservation of light flux and directionality. All first optical fibers 33 are connected to a second optical fiber 32 at their ends through optical path combining technology, thereby unifying and integrating multiple optical signals into a single high-energy-density, highly uniform composite ultraviolet beam.

[0057] Furthermore, the output structure can also be connected to the second endoscope 61 to output an infrared beam to the patient's lesion for positioning. The output ports of the infrared beam and the ultraviolet beam are different. This step significantly improves the spatial utilization efficiency and system output stability of ultraviolet and infrared light, reduces the risk of uneven irradiation caused by the divergence of multiple light sources, and enhances the operability and adaptability of the device through the flexible transmission characteristics of the fiber bundle, which helps to achieve high-precision and highly controllable ultraviolet therapy output in complex clinical scenarios.

[0060] The system of this invention uses the ultraviolet light device described above as its core functional component, constructing a complete corneal cross-linking treatment system. By organically integrating the aforementioned optics, light source, heat dissipation, and output structure into the system architecture, it ensures that each component works collaboratively to achieve stable output and precise irradiation of the ultraviolet beam. This integrated design not only enhances the overall controllability and stability of the system but also provides a modular and scalable platform for clinical applications. The sub-modules complement and collaborate through clear functional divisions. This system design achieves efficient end-to-end control from ultraviolet light generation, shaping, transmission to output, enabling ultraviolet light irradiation to possess high energy density, high spatial consistency, and high repeatability. This significantly improves the efficacy and safety of corneal cross-linking treatment while also reducing the operator's learning curve and system maintenance costs.
