Description

Technical Field

[0001] This utility model relates to the field of occlusion technology for vitiligo treatment devices, and in particular to an adjustable auxiliary occlusion device for vitiligo treatment devices. Background Technology

[0002] Vitiligo treatment devices are medical devices that assist in the treatment of vitiligo. They mainly work through specific physical or optical principles. Common types include phototherapy equipment such as 308nm excimer laser, low-energy laser therapy devices, and auxiliary physiotherapy devices. Their core function is to stimulate the activity of melanocytes in the affected area, promote melanin production, and at the same time improve local blood circulation and cell repair environment, helping the white patches to repigment.

[0003] Currently, there are two problems in the use of handheld vitiligo treatment devices: First, the controller of the treatment device lacks a special protective structure, and it is easily damaged by collision and friction during use or storage, affecting the normal operation of the device; Second, the irradiation area of ​​the treatment light source cannot be flexibly adjusted. When patients need to irradiate the lesion, they often need to manually limit the irradiation range by covering normal skin with stickers, which is cumbersome, inefficient, and inconvenient for patients.

[0004] Therefore, it is necessary to provide a new adjustable auxiliary shielding device for vitiligo treatment to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable auxiliary shielding device for a vitiligo treatment instrument.

[0006] The adjustable auxiliary shielding device for vitiligo treatment provided by this utility model includes: a treatment head, a controller fixedly connected to the top of the treatment head, a handle fixedly connected to one side of the treatment head, a treatment lamp fixedly connected inside the treatment head, a protective cover rotatably connected to the end of the treatment head away from the handle, limit blocks symmetrically fixedly connected to the side of the protective cover near the handle, limit grooves formed inside the limit blocks, shielding plates equidistantly installed at the bottom of the treatment head, telescopic plates equidistantly installed at the bottom of the treatment head, a guide post fixedly connected to the top of the shielding plates, a limiting component for limiting the limit blocks installed inside the handle, and a driving component for driving the guide post to move inside the treatment head.

[0007] Preferably, the limiting component includes: a lifting block, a sliding column, a spring, a connecting rod, and a pressing block. The lifting block is slidably connected inside the grip handle, and the sliding column is slidably connected inside the grip handle. One end of the sliding column is fixedly connected to the lifting block, and a spring is sleeved on the outer wall of the sliding column. One end of the spring is fixedly connected to the lifting block, and the other end of the spring is fixedly connected to the grip handle. A connecting rod is symmetrically rotatably connected to one side of the lifting block, and pressing blocks are symmetrically slidably connected inside the grip handle. The ends of the two connecting rods away from the lifting block are fixedly connected to the corresponding pressing blocks.

[0008] Preferably, the drive assembly includes: a rotating rod, a worm gear, a worm wheel, and a guide disk. The rotating rod is rotatably connected inside the treatment head, the worm gear is fixedly connected to the outer wall of the rotating rod, the worm wheel is rotatably connected inside the treatment head, the worm wheel meshes with the worm gear, the guide disk is fixedly connected inside the worm wheel, and guide grooves are equidistantly opened inside the guide disk. Multiple sets of guide posts slide inside the corresponding guide grooves.

[0009] Preferably, one end of the rotating rod passes through the treatment head and is fixedly connected to a rotating tooth.

[0010] Preferably, the ends of the two extrusion blocks furthest from the lifting block are both designed at an angle.

[0011] Preferably, the cover is transparent.

[0012] Preferably, the multiple sets of guide grooves are of an arc shape.

[0013] Compared with related technologies, the adjustable auxiliary shielding device for vitiligo treatment provided by this utility model has the following beneficial effects:

[0014] Protection controller:

[0015] This device features an openable and closable protective cover structure, which provides targeted protection for the controller when the handheld vitiligo treatment device is used or stored. During use, it can prevent damage to the controller from accidental collisions and friction during operation, and when stored, it can isolate the controller from dust, moisture and external impacts, reducing the risk of controller malfunction due to long-term storage.

[0016] Improve ease of use:

[0017] This device, through its adjustable shield and drive components, enables flexible adjustment of the treatment light source's irradiation area. Patients no longer need to use cumbersome manual methods such as applying stickers to cover the area; a simple operation is all that's required to match the size of the lesion area. This significantly simplifies the operation process and improves efficiency. At the same time, precise irradiation range control prevents normal skin from being exposed to the treatment light, eliminating the safety hazards of easy displacement and inaccurate coverage associated with manual shielding. This ensures both treatment effectiveness and improved safety and patient experience. Attached Figure Description

[0026] It should be noted that: the two sides of the shielding plate 8 are fixedly connected to the corresponding telescopic plates 9 respectively; the treatment lamp 4 is located on the central axis formed by multiple shielding plates 8; the controller 2 is used to control the working state of the treatment lamp 4 inside the treatment head 1; the handle 3 makes it convenient for the operator to hold the treatment device; the whole device, through the cooperation of limiting components, driving components, etc., realizes the stable opening and closing of the cover 5 and the flexible adjustment of the shielding plate 8, meeting the auxiliary shielding needs in the process of vitiligo treatment; the telescopic plate 9 is made of silicone; both the shielding plate 8 and the telescopic plate 9 have good shielding effect.

[0027] Please see Figure 1 and Figure 2 The limiting components include: a lifting block 21, a sliding column 22, a spring 23, a connecting rod 24, and a pressing block 25. The lifting block 21 is slidably connected inside the grip handle 3, and the sliding column 22 is slidably connected inside the grip handle 3. One end of the sliding column 22 is fixedly connected to the lifting block 21. The outer wall of the sliding column 22 is fitted with a spring 23. One end of the spring 23 is fixedly connected to the lifting block 21, and the other end of the spring 23 is fixedly connected to the grip handle 3. The connecting rod 24 is symmetrically rotatably connected to one side of the lifting block 21. The pressing block 25 is symmetrically slidably connected inside the grip handle 3. The ends of the two connecting rods 24 away from the lifting block 21 are fixedly connected to the corresponding pressing blocks 25. The ends of the two pressing blocks 25 away from the lifting block 21 are both designed at an angle.

[0028] It should be noted that: one end of the lifting block 21 passes through the top of the grip handle 3, and one end of each of the two pressing blocks 25 extends outside the grip handle 3. The pressing blocks 25 and the limiting groove 7 can be connected together.

[0029] Please see Figure 1 and Figure 4 The drive assembly includes a rotating rod 31, a worm gear 32, a worm wheel 33, and a guide disk 34. The rotating rod 31 is rotatably connected inside the treatment head 1. The worm gear 32 is fixedly connected to the outer wall of the rotating rod 31. The worm wheel 33 is rotatably connected inside the treatment head 1. The worm wheel 33 meshes with the worm gear 32. The guide disk 34 is fixedly connected inside the worm wheel 33. Multiple sets of guide grooves 35 are equidistantly formed inside the guide disk 34. The multiple sets of guide posts 10 slide inside the corresponding guide grooves 35. One end of the rotating rod 31 passes through the treatment head 1 and is fixedly connected to a helical tooth 41. The multiple sets of guide grooves 35 are arc-shaped.

[0030] It should be noted that the rotating tooth 41 is located on the right side of the treatment head 1. When the operator can grasp the handle 3 with their right hand, they can use their index finger to touch and rotate the rotating tooth 41, easily achieving the effect of operating the device with one hand.

[0031] The working principle of the adjustable auxiliary shielding device for vitiligo treatment provided by this utility model is as follows:

[0032] Open the protective cover 5:

[0033] In its natural state, spring 23 is in the extended state, which pushes lifting block 21 upward. Lifting block 21, through connecting rod 24, causes pressing block 25 to extend, inserting into limiting groove 7 and restricting limiting block 6. At this time, cover 5 is fixed and cannot be opened. When it is necessary to open cover 5, press lifting block 21. Lifting block 21 drives sliding column 22 to slide inside handle 3, while compressing spring 23. During the movement of lifting block 21, pressing block 25 is pulled into handle 3 through connecting rod 24, so that pressing block 25 releases the restriction. When the limit block 6 is in position, rotating the cover 5 allows the limit block 6 near the handle 3 to move freely, opening the cover 5. To close the cover 5, first press the lifting block 21, then close the cover 5, and then release the lifting block 21. The spring force of the spring 23 pushes the lifting block 21 to reset, and the lifting block 21 drives the squeezing block 25 to extend again through the connecting rod 24, re-limiting the limit block 6 and fixing the cover 5. The cover 5 is transparent, which can protect the controller 2 on the top of the treatment head 1 when closed, without affecting the observation of the display screen on the controller 2.

[0034] Baffle 8 adjustment:

[0035] Rotating the rotating rod 31 via the helical gear 41 causes the worm gear 32 to rotate, and the worm wheel 33 meshing with the worm gear 32 rotates accordingly. This, in turn, causes the guide disk 34 inside the worm wheel 33 to rotate. The arc-shaped guide groove 35 on the guide disk 34 drives the corresponding guide post 10 to move. The guide post 10 drives the top-fixed shielding plate 8 to move. At the same time, the telescopic plate 9 at the bottom of the treatment head 1 can cooperate with the movement of the shielding plate 8 to ensure the continuity and stability of the shielding. In this way, the position of the shielding plate 8 can be adjusted according to the patient's needs, so as to achieve precise control of the treatment light irradiation range.

[0036] First, rotate the rotary gear 41 to adjust the coverage of the shielding plate 8 and the telescopic plate 9 to fit the patient's lesion area. Then, press the lifting block 21 and open the cover 5. Operate the controller 2 to select the irradiation intensity and irradiation range of the treatment lamp 4. Then close the cover 5 to avoid accidental contact or damage to the controller 2 during treatment.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
