[0031] Current laser protective glasses utilize lens coatings and special lens materials to reflect or absorb specific wavelengths of laser or intense light, causing them to attenuate and thus achieving a protective effect. However, while protecting against specific wavelengths of laser or intense light, laser protective glasses often cause attenuation of other visible light wavelengths, affecting the accurate observation of the skin by medical personnel during surgery or treatment, and increasing their workload. To address the problem of excessive workload for medical personnel, this application provides a low-operation-burden protective eyewear and its control system, the specific structure of which is shown in the following embodiment.
[0032] Example 1
[0033] This application provides a protective eyewear system for enhancing skin visibility, such as... Figure 1 and Figure 2 As shown, the device includes a frame 10 and two mounting brackets 20. The frame 10 includes a housing 110 for holding a protective lens 40 and temples 120 for wearing on the operator. The frame 10 is equipped with a supplementary light 30 and a protective lens 40 with laser band protection function. The protective lens 40 is used to reflect or absorb laser light to protect the operator's eyes. The laser wavelength corresponding to the protective lens 40 can be at least one of 190nm, 266nm, 355nm, 515nm, 532nm, 595nm, 633nm, 650nm, 694nm, 755nm, 800nm, 810nm, 1030nm, 1064nm, 1080nm, 1320nm, 1550nm, and 10600nm. A first polarizing element 60 is provided in the light output path of the supplementary light 30, such as... Figure 4As shown, the supplementary light 30 is used to supplement the field of vision area of the protective glasses. The supplementary light 30 enhances the light intensity in the field of vision area, allowing the light generated by the supplementary light 30 to pass through the first polarizing element 60 and illuminate the field of vision area. After reflection in the field of vision area, it passes through the second polarizing element 50 and the protective lens 40 and enters the operator's field of vision, thereby offsetting or reducing the attenuation effect of the protective lens 40 on non-target laser wavelengths. This allows the operator to more clearly distinguish target objects in the field of vision area and reduces the strain on the operator's eyes. The field of vision area refers to the field of vision observed by the operator wearing protective glasses through the protective lens 40.
[0034] The mounting bracket 20 is rotatably connected to the lens frame 10 around the axis of the mounting bracket 20. The mounting bracket 20 is correspondingly arranged with the protective lens 40. The mounting bracket 20 is provided with a mounting cavity for placing the second polarizing element 50. The second polarizing element 50 and the protective lens 40 are coaxially arranged. By rotating the mounting bracket 20, the polarization angle of the first polarizing element 60 and the second polarizing element 50 can be controlled and adjusted. Preferably, the adjustment range of the polarization angle is 0° to 90°. When the supplementary light 30 is working and the polarization angle is 0°, the first polarizing element 60 and the second polarizing element 50 can be used to clearly see the image structure of the skin surface in the field of vision. When the supplementary light 30 is working and the polarization angle is 90°, the first polarizing element 60 and the second polarizing element 50 can be used to clearly see the structure of the subepidermal layer of the skin in the field of vision, effectively improving the flexibility of the protective glasses. At the same time, due to the gradual adjustment of the polarization angle, the light presented to the operator's field of vision changes gradually, allowing the operator to better adapt to the transition, thereby reducing the operator's eye strain and reducing workload.
[0035] In some embodiments, only the first polarizing element 60 can be rotatably connected to the lens frame 10 about the axis of the first polarizing element 60, instead of the mounting frame 20 being rotatably connected to the lens frame 10 about the axis of the mounting frame 20. During installation, the mounting frame 20, the second polarizing element 50, and the fill light 30 can be assembled with the lens frame 10 first, and then the first polarizing element 60 can be installed on the lens frame 10 according to the positions of the second polarizing element 50 and the fill light 30. This can reduce the installation accuracy requirements of the mounting frame 20, the second polarizing element 50, and the fill light 30, and reduce production costs. In addition, since the first polarizing element 60 only needs to be adapted to the size of the fill light 30, and is relatively small compared to the size of the protective lens 40, the frictional resistance during rotation is also relatively small. Only a small driving force is needed to rotate the first polarizing element 60, and the polarization angle between the first polarizing element 60 and the second polarizing element 50 can be controlled and adjusted.
[0036] In some embodiments, the mounting bracket 20 and the lens frame 10 can be rotatably connected around the axis of the mounting bracket 20, and the first polarizing element 60 and the lens frame 10 can be rotatably connected around the axis of the first polarizing element 60, thereby improving operational flexibility.
[0037] It should be noted that the rotatable connection between the mounting bracket 20 and the lens frame 10, and the rotatable connection between the first polarizing element 60 and the lens frame 10 are existing technologies. Specifically, the rotatable connection can be achieved through clearance fit, bearing fit, track fit, etc., and no specific limitation is made here.
[0038] To improve the ease of adjustment, when the mounting bracket 20 and the lens frame 10 are rotatably connected around the axis of the mounting bracket 20, the two mounting brackets 20 can also be rotatably connected. That is, only one mounting bracket 20 needs to be adjusted, and the other mounting bracket 20 will move synchronously. This allows for the synchronous adjustment of the two second polarization elements 50 in one operation, effectively reducing the operator's workload and improving the accuracy and convenience of adjustment.
[0039] To achieve synchronous rotational connection between the two mounting brackets 20, such as Figures 1-3 As shown, multiple teeth 210 can be provided on the edge of the mounting bracket 20, and the two mounting brackets 20 can be connected by the teeth 210 to achieve synchronous rotation between the two mounting brackets 20. Preferably, the teeth 210 are located on the same circumference.
[0040] In some embodiments, to achieve synchronous rotational connection between the two mounting brackets 20, such as Figure 5 As shown, the two mounting brackets 20 can also be connected by a linkage 70. The linkage 70 can be a transmission gear, which meshes with the two mounting brackets 20 respectively, so that the two mounting brackets 20 rotate synchronously and in the same direction.
[0041] To constrain the rotational travel of the mounting bracket 20 or the first polarizing element 60 on the lens frame 10, a limiting mechanism can be provided on the lens frame 10. The limiting mechanism is used to limit the rotational travel of the mounting bracket 20 or the first polarizing element 60 on the lens frame 10. For example, the rotational travel of the mounting bracket 20 and the lens frame 10 includes a first position state and a second position state. In the first position state, the polarization angle between the first polarizing element 60 and the second polarizing element 50 is 0°. In the second position state, the polarization angle between the first polarizing element 60 and the second polarizing element 50 is 90°. Preferably, the first position state corresponds to the upper limit of the rotational travel, and the second position state corresponds to the lower limit of the rotational travel.
[0042] It should be noted that the limiting mechanism is existing technology. Specifically, the corresponding arc of the teeth 210 on the mounting frame 20 can be a preset arc, and the limiting constraint can be achieved by using the meshing stroke. Alternatively, the limiting mechanism can be a sliding groove on the frame 10 and a slider on the mounting frame 20 or the first polarizing element 60. The slider slides in conjunction with the sliding groove, and the limiting constraint can be achieved by using the sliding stroke of the slider in the sliding groove.
[0043] In some embodiments, when the first polarizing element 60 is rotatably connected to the frame 10, the rotational stroke of the first polarizing element 60 and the frame 10 includes a first position state and a second position state. In the first position state, the polarization angle between the first polarizing element 60 and the second polarizing element 50 is 0°. In the second position state, the polarization angle between the first polarizing element 60 and the second polarizing element 50 is 90°. Preferably, the first position state corresponds to the upper limit of the rotational stroke, and the second position state corresponds to the lower limit of the rotational stroke.
[0044] To improve the flexibility of the supplementary effect, N supplementary lights 30 can be installed on the frame 10. At least two of the N supplementary lights 30 produce light of different wavelengths, and N≥2. Depending on the usage environment, the appropriate supplementary light 30 can be selected to supplement the light intensity of the field of vision area.
[0045] Preferably, N supplementary lights 30 are symmetrically arranged on the frame 10.
[0046] To reduce the attenuation effect of the protective lens 40 on non-target bands, an anti-reflection coating can be provided on the protective lens 40 or the second polarizing element 50 to improve the transmittance of non-target bands.
[0047] Example 2
[0048] This application provides a control system for protective glasses, including a treatment handpiece and the protective glasses in Embodiment 1. The treatment handpiece is communicatively connected to the protective glasses, and a human-computer interaction module is provided on the treatment handpiece.
[0049] The treatment handpiece is a handpiece for a laser therapy device. The operator can input control commands through the human-computer interaction module on the treatment handpiece to control the working status of the supplementary light 30. When multiple supplementary lights 30 of different wavelengths are set on the protective glasses, the operator can input control commands through the human-computer interaction module on the treatment handpiece to select a specific wavelength of supplementary light 30 and control its working status, thereby improving the ease of operation.
[0050] Specifically, a cable 80 is provided on the temple 120 of the eyeglass frame 10, and the supplementary light 30 is connected to the treatment handpiece via the cable 80.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
