[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see Figures 1-9 A semiconductor laser photodynamic therapy device with ultraviolet light photography function includes a machine base 1 and a multi-axis robotic arm 2 fixedly connected to the machine base 1. A treatment head 3 is installed on the multi-axis robotic arm 2. The position of the treatment head 3 can be adjusted by activating the multi-axis robotic arm 2, and then the treatment head 3 can be activated to emit light to treat the patient.

[0042] The core of this technical solution lies in the fact that the upper side of the machine base 1 is equipped with:

[0043] The grid treatment area 4 includes multiple small grid areas arranged in a rectangular array. The small grid areas arranged along the X direction form a column, and the small grid areas arranged along the Y direction form a row. The small grid areas on the upper side of the grid treatment area 4 that are obscured by the patient are valid grid areas, and the small grid areas on the upper side of the grid treatment area 4 that are not obscured by the patient are invalid grid areas. The invalid grid area located between two valid grid areas is judged as a virtual grid area.

[0044] The detection unit is used to determine whether a small grid area is an invalid grid partition. If it is not an invalid grid partition, it is either a valid grid partition or a virtual grid partition.

[0045] Multiple camera devices 8, each equipped with a rotatable camera, are used to capture images of the patient's skin and generate photographic files.

[0046] The spacing adaptive device 7 has an effective installation area with adjustable width. Multiple camera devices 8 are installed in a row on the effective installation area of ​​the spacing adaptive device 7. The spacing adaptive device 7 is used to adjust the spacing of the multiple camera devices 8 within the effective installation area so that the multiple camera devices 8 are arranged at equal intervals.

[0047] A moving unit is installed on the upper side of the machine base 1, and the spacing adaptive device 7 is installed on the moving unit. The moving unit is used to drive the spacing adaptive device 7 to move along the X-axis direction.

[0048] Width limiting unit 6, installed on the moving unit, is used to adjust the effective installation area width of the spacing adaptive device 7 according to the total length of the effective grid partitions and virtual grid partitions in the same row of small grid areas, so that the effective installation area width is the same as the total length of the effective grid partitions and virtual grid partitions.

[0049] Ultraviolet lamp 31, installed on the spacing adaptive device 7, is used to irradiate ultraviolet light into the small grid treatment area 4, and the condition of the patient's skin is indicated by the color change of the patient's skin after irradiation with ultraviolet light.

[0050] When in use, the patient places the body to be treated on the grid treatment area 4, and then the infrared measuring instrument 5 on both sides of the grid treatment area 4 measures the distance between the body and the infrared measuring instrument 5 to obtain the width measurement value. The number of small grid areas not covered by the body can be obtained by dividing the width measurement value by the width of the small grid area. These small grid areas are invalid grid partitions.

[0051] Then, the spacing adaptive device 7 is moved by the moving unit, so that the spacing adaptive device 7 can move from the multi-row small grid area;

[0052] When the spacing adaptive device 7 moves to each row of small grid areas, the width of the effective installation area of ​​the spacing adaptive device 7 is adjusted by the width limiting unit 6. The spacing adaptive device 7 drives multiple camera devices 8 to adaptively adjust within the effective installation area of ​​the spacing adaptive device 7, so that the multiple camera devices 8 are arranged at equal intervals. At this time, the total length of the same group of effective grid partitions and virtual grid partitions is divided into shooting areas with the same number of camera devices 8. Each camera device 8 is directly opposite each shooting area, allowing the camera device 8 to shoot the patient in its corresponding shooting area.

[0053] The process continues until the spacing adaptive device 7 moves to the end, completing the imaging of all patients;

[0054] In summary, this embodiment uses an infrared measuring instrument 5 to determine the patient's affected body position. Then, the width limiting unit 6 and the spacing adaptive device 7 automatically adjust the spacing of the camera devices 8 as they move, allowing the shooting areas of multiple camera devices 8 to match the patient's position. This reduces the ineffective shooting areas of the camera devices 8, concentrates all camera devices 8 to shoot the patient's body, and enables the rapid movement of multiple camera devices 8 on the patient's body, reducing ineffective movement of multiple camera devices 8 on the patient's body surface and improving the movement efficiency of the camera devices 8. As a result, the camera devices 8 can complete the shooting of the patient's body surface with a smaller distance, improving the shooting efficiency. Moreover, the structure is relatively simple and the production cost is low.

[0055] Example 2:

[0056] Please see Figure 1 and Figures 3-4As shown, this embodiment discloses in detail a structure of the spacing adaptive device 7 based on embodiment 1. The spacing adaptive device 7 includes a moving rail 9 connected to a moving unit. An ultraviolet lamp 31 is fixedly connected to the moving rail 9. The moving rail 9 is a hollow rectangular structure with openings on its upper and lower sides. Two limiting pieces 11 and multiple moving seats 10 are slidably connected inside the moving rail 9. Support legs 14 connected to the width limiting unit 6 are fixedly connected to the limiting pieces 11. The two limiting pieces 11 are located on both sides of the multiple moving seats 10. Multiple camera devices 8 are respectively installed on the lower side of the multiple moving seats 10. The position of the camera device 8 can be adjusted by adjusting the position of the moving seats 10.

[0057] The effective installation area of ​​the spacing adaptive device 7 is the area inside the moving rail 9 and located between the two limiting pieces 11. In order to drive multiple moving seats 10 to move adaptively within the effective installation area, elastic elements 12 are installed between two adjacent moving seats 10 and between adjacent moving seats 10 and limiting pieces 11. At this time, the moving seats 10 can be automatically adjusted by the elastic action of the elastic elements 12.

[0058] The elastic element 12 can be any one of a return spring, a tension spring, and a tension rope; in this technical solution, it is a return spring.

[0059] Please refer to Figures 3-4 As shown, in order to improve the running stability of the movable seat 10, the limiting piece 11 and the elastic member 12, a horizontally arranged guide rod 13 is fixedly connected inside the movable rail 9. A horizontally arranged through hole 25 is opened in the middle position of the limiting piece 11 and the movable seat 10. The movable seat 10 and the limiting piece 11 are slidably connected to the outside of the guide rod 13 through the through hole 25, and the elastic member 12 is sleeved on the outside of the guide rod 13. At this time, the movable seat 10, the limiting piece 11 and the elastic member 12 can be limited by the guide rod 13, so that the movable seat 10, the limiting piece 11 and the elastic member 12 can only slide horizontally.

[0060] In summary, in this embodiment, by using the elastic force of the elastic element 12 to drive the movable seat 10 to slide, the position of the movable seat 10 and the camera device 8 can be automatically adjusted according to the material properties, thereby reducing production costs.

[0061] Example 3:

[0062] Please see Figure 1 and Figure 5As shown, this embodiment describes a structure of the moving unit in detail based on embodiment 2. Specifically, the moving unit includes a side support 15 fixedly connected to the machine base 1. A transverse rail 29 is fixedly connected to the side support 15. A moving trolley 30 fixedly connected to the moving rail 9 is mounted on the transverse rail 29. At this time, by starting the moving trolley 30, the moving trolley 30 can be moved on the transverse rail 29, thereby moving the moving rail 9.

[0063] Example 4:

[0064] Please see Figure 1 and Figures 5-6 As shown, this embodiment describes a structure of the width limiting unit 6 in detail based on embodiment 3. Specifically, the width limiting unit 6 includes track adjustment components that are fixedly connected to two side supports 15 respectively. Plastic rails 17 are installed on the side of the two track adjustment components that are close to each other, and two legs 14 are slidably connected to the two plastic rails 17 respectively.

[0065] At this time, by activating the track adjustment component, the two plastic rails 17 are adjusted so that the distance between the two plastic rails 17 is automatically adjusted. When the support leg 14 slides on the plastic rail 17, the distance between the two support legs 14 will automatically change as the distance between the two plastic rails 17 changes, thereby achieving the purpose of automatically adjusting the distance between the support legs 14.

[0066] Please see here. Figure 4 and Figures 7-8 As shown, the support leg 14 includes a connecting rod 22 fixedly connected to the upper side of the limiting plate 11. A disc foot 23 is fixedly connected to the upper side of the connecting rod 22. The outer diameter of the disc foot 23 is larger than the outer diameter of the connecting rod 22. The plastic rail 17 has a guide groove 24 with an opening at the lower side. The inner diameter of the guide groove 24 is larger than the inner diameter of its opening. The disc foot 23 is slidably connected inside the guide groove 24. The shape setting can reduce the phenomenon of the disc foot 23 falling off during the sliding process inside the guide groove 24.

[0067] Please see Figures 5-6 As shown, the structure of the track adjustment component is described in detail here. The track adjustment component includes multiple electric push rods fixedly connected to the same width limiting unit 6. Among them, the two electric push rods located at both ends of the side bracket 15 are the initial electric push rod 20 and the end electric push rod 21, respectively. The piston rod of the initial electric push rod 20 is connected to the end of the plastic rail 17, and the piston rod of the end electric push rod 21 is fixedly connected to the winding member 19. The winding member 19 is connected to the end of the plastic rail 17 away from the initial electric push rod 20. At this time, the plastic rail 17 is wound up by the winding member 19, so that the plastic rail 17 is in a taut state, reducing the shaking phenomenon generated when the support leg 14 slides on the plastic rail 17.

[0068] Please see Figure 5 and Figure 9 As shown, in order to adjust the spacing of the middle position of the plastic rail 17, multiple electric push rods located in the middle of the side bracket 15 are called middle electric push rods 16. The piston rod of the middle electric push rod 16 is fixedly connected to a movable connecting piece 18 that is slidably connected to the plastic rail 17. By starting the middle electric push rod 16 and adjusting the position of the movable connecting piece 18, the position of the middle position of the plastic rail 17 can be adjusted.

[0069] Specifically, the movable connector 18 includes a bottom rod 26 fixedly connected to the piston rod of the intermediate electric push rod 16. The lower part of the bottom rod 26 is fixedly connected to two parallel vertical rods 27. Rotating rings 28 are rotatably connected to the outer sides of the two vertical rods 27. The distance between the two rotating rings 28 is greater than the width of the plastic rail 17. The lower end of the vertical rod 27 is fixedly connected to a limiting bottom bracket 32. The limiting bottom bracket 32 ​​can limit the plastic rail 17 between the two rotating rings 28, allowing the limiting bottom bracket 32 ​​to limit the plastic rail 17.

[0070] Example 5:

[0071] Please see Figure 1 As shown, this embodiment discloses the structure of the detection unit based on the above embodiment. Specifically, the detection unit includes two sets of infrared measuring instruments 5. The two sets of infrared measuring instruments 5 are installed on the upper side of the machine base 1 and are located on both sides of the grid treatment area 4. Each set of infrared measuring instruments 5 has multiple instruments. The multiple infrared measuring instruments 5 are respectively opposite to multiple rows of small grid areas. The infrared measuring instruments 5 are used to measure the distance between the patient on the grid treatment area 4 and the infrared measuring instruments 5.

[0072] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
