Description

Technical Field

[0001] The invention relates to the technical field of laser treatment equipment for herpes zoster, and in particular to a laser equipment for treating postherpetic neuralgia. Background Art

[0002] Herpes zoster is an acute skin disease caused by the varicella-zoster virus. Children who are not immune to this virus will develop chickenpox after being infected. Some people do not develop chickenpox after being infected. This is a latent infection and they become carriers of the virus. This virus is neurotropic. After invading the sensory nerve endings of the skin, it can move along the nerves to the ganglia of the posterior roots of the spinal cord and lurk there. When the host's cellular immune function is low, such as when suffering from a cold, fever, systemic lupus erythematosus, and malignant tumors, the virus is stimulated again, causing inflammation and necrosis of the ganglia. At the same time, the reactivated virus can move along the peripheral nerve fibers to the skin to cause herpes and pain. The older the age, the more severe the neuralgia. If the virus in the body and the virus transmitted to the peripheral nerves are cleared from the body, there will be no sequelae. Otherwise, postherpetic neuralgia may occur.

[0046] As an optimization technical solution of the present invention, the spherical connection between the lifting component 2 and the irradiation head 3 facilitates the angle adjustment of the irradiation head 3 so that it can complete irradiation treatment at a certain angle, and the LED lamp 31 is used to provide a light source to cooperate with the shielding mechanism 5 to form a shadow area on the patient's skin, so that the skin can be covered by the shadow area, which plays a good protective role. The cooling component 8 cools the skin in time after the skin treatment is completed to reduce skin discomfort.

[0047] In the above scheme, the lifting assembly 2 includes a lifting base 21, a lifting rod 22 and a first connecting ball 23. The lifting base 21 is arranged in the laser base 1. The first connecting ball 23 is connected to the output end of the lifting base 21 through the lifting rod 22. The first connecting ball 23 is spherically connected to the bottom of the irradiation head 3, which can control the lifting and lowering of the irradiation head 3 and adjust the irradiation angle of the irradiation head 3, so that it can achieve a better cooling effect.

[0048] In the above scheme, the fixed plate 4 is connected to the universal mechanism 6 via a telescopic connector 43 , a plurality of inwardly curved guide grooves 42 are provided at the bottom of the fixed plate 4 , and the shielding mechanism 5 is connected to the bottom of the fixed plate 4 via the guide grooves 42 .

[0049] As an optimized technical solution of the present invention, the telescopic connecting member 43 includes a telescopic part 431 and a connecting part 432. The telescopic part 431 is connected to the connecting part 432. The connecting part 432 is fixed to the universal mechanism 6 by screws. The position can be adjusted by loosening the screws. The telescopic part 431 can be telescoped to facilitate adjustment of the position of the fixed plate 4.

[0050] A rotation groove 41 is provided on one side of the fixed disk 4, and the telescopic part 431 is rotatably connected in the rotation groove 41 to facilitate the rotation of the fixed disk 4. A locking rod 44 is also provided on the side of the fixed disk 4. When the shielding mechanism 5 realizes the definition of the outline of the shingles, it is locked to prevent the area defined by the shielding mechanism 5 from changing.

[0051] In the above scheme, the shielding mechanism 5 includes an expansion component, a rotating disk 53 and a shielding component. A plurality of sliding grooves 531 are provided on the top of the rotating disk 53. A guide rod 56 is slidably connected in the sliding groove 531. The inner end of the guide rod 56 is movably connected in the guide groove 42. The outer end of the guide rod 56 is connected to the expansion component. The expansion component is located on the outside of the rotating disk 53. The shielding component is located directly below the rotating disk 53. A sliding rod 57 is provided at the bottom of the expansion component. The shielding component is movably connected to the sliding rod 57 through an adjusting rod.

[0052] A temperature probe 9 is connected to the bottom of any slide bar 57. When the laser head is used to irradiate the target area for treatment, the temperature probe 9 detects the skin surface temperature until a terminal reaction occurs at 42 degrees Celsius, indicating that the treatment is effective.

[0053] As an optimization technical solution of the present invention, the guide rod 56 can slide in the sliding groove 531, and when the rotating disk 53 rotates, the inner end of the guide rod 56 will slide along the guide groove 42 from the direction close to the center end to the direction away from the center end, that is, the guide rod 56 moves eastward along the sliding groove 531 to the outside, and then through the connection relationship between the guide rod 56 and the expansion component, the expansion component can be driven to expand, thereby increasing the radius of the irregular shape formed by the expansion component and reducing the shielding coverage range.

[0054] In the above scheme, the expansion component includes a plurality of first arc expansion bars 51 and second arc expansion bars 52. The first arc expansion bars 51 are located at the lower side of the second arc expansion bars 52 and are staggered with each other. The second arc expansion bars 52 are penetrated by an arc groove 521. The two ends of the first arc expansion bar 51 are respectively movably connected to the two sides of the arc groove 521, and the outer end of the guide rod 56 is connected to the middle of the arc groove 521.

[0055] As an optimization technical solution of the present invention, multiple first arc expansion strips 51 and second arc expansion strips 52 overlap and are staggered to form an irregular circle wrapped around the outside of the rotating disk 53, and the purpose of expansion or contraction can be achieved by utilizing the connection and matching relationship between the two.

[0056] In the above scheme, the shielding assembly includes a trapezoidal shielding plate 54 and a fan-shaped shielding plate 55. The bottom of the trapezoidal shielding plate 54 is movably connected to the sliding rod 57 through an adjusting rod. A first adjusting rod 551 is provided on one side of the fan-shaped shielding plate 55. The outer end of the first adjusting rod 551 is hinged to one side of the top of the trapezoidal shielding plate 54. The other side of the top of the trapezoidal shielding plate 54 is hinged to a second adjusting rod 552. The inner end of the second adjusting rod 552 is movably connected to the inner end of the first adjusting rod 551.

[0057] As an optimization technical solution of the present invention, the adjusting rod includes an adjusting rod 1 541 and an adjusting rod 2 542, and the adjusting rod 1 541 and the adjusting rod 2 542 are movably connected together through a keyway connection relationship, so that when the expansion component is expanded, the adjusting rod 1 541 can be driven to move outward through the sliding rod 57. When the adjusting rod 1 moves to a certain position, it will pull the adjusting rod 2 542 to move outward, thereby reducing the shielding coverage range. By adjusting the first adjusting rod 551 and the second adjusting rod 552 on both sides of the fan-shaped shielding plate 55, the fan-shaped shielding plate 55 can be folded inward, so as to cooperate with the irradiation of the LED lamp 31 to achieve the outlining of the skin contour of the person suffering from herpes zoster.

[0058] In the above scheme, the universal mechanism 6 includes a splint 61, a support rod 63 and a second connecting ball 64. There are three splints 61 from top to bottom, and two adjacent ones are arranged perpendicular to each other. The second connecting balls 64 are arranged at both ends of the support rod 63, and the second connecting balls 64 are spherically connected in the splint 61.

[0059] As an optimization technical solution of the present invention, the two lower ones of the three clamps 61 are vertically arranged, and the top one is horizontally arranged. The spherical connection of the second connecting balls 64 at both ends of the support rod 63 can realize all-round and multi-angle rotation, so that it can irradiate many positions that are inconvenient to irradiate, so as to improve the applicability of the equipment.

[0060] In the above scheme, the upper clamping plate 61 is movably connected with a clamping hoop 62, which is clamped on the laser base 1, and the lower clamping plate 61 is movably connected with a U-shaped block 65, which is connected with a clamping member 7 for fixing the universal mechanism 6.

[0061] As an optimized technical solution of the present invention, the clamping hoop 62 is two clamping parts fixed by bolts to achieve the purpose of fixing the laser base 1, and the clamping member 7 is composed of a threaded connection end 71 and a clamping end 72. The threaded connection end 71 is threadedly connected in the U-shaped clamping block 65, and the universal mechanism 6 can be clamped in any convenient place for fixing. At the same time, secondary fixation can be achieved through the clamping end 72, making its fixation more stable.

[0062] In the above scheme, the cooling component 8 includes a water-cooling base 81 and a cooling surface 82 . The water-cooling base 81 is arranged at the bottom of the laser base 1 . The cooling surface 82 is connected to the bottom of the laser base 1 through the bracket 12 . The cooling surface 82 is connected to the water-cooling base 81 .

[0063] As an optimization technical solution of the present invention, the water-cooled base 81 in the cooling component 8 can utilize the semiconductor refrigeration principle to achieve a cooling effect on the surface, and form a water circulation in the cooling surface 82, so that the cooling surface 82 can always achieve a better cooling effect.

[0064] The specific implementation cases are:

[0065] When performing laser treatment on patients with herpes zoster, the device is first fixed in a convenient fixed position by the clamp 7, the universal mechanism 6 is moved so that the irradiation head 3 and the shielding mechanism 5 correspond to the desired treatment position, and the position of the shielding mechanism 5 is adjusted by the telescopic connecting member 43 so that it is located directly below the irradiation head 3 and fixed.

[0066] Next, the rotating disk 53 is rotated. Through the active action of the rotating disk 53 and the matching relationship between the guide groove 42 and the guide rod 56 provided at the bottom of the fixed disk 4, the inner end of the guide rod 56 will slide along the guide groove 42 from the direction close to the center end to the direction away from the center end, and then the guide rod 56 will slide outward along the sliding groove 531, and the outer end of the guide rod 56 can drive the second arc expansion bar 52 to expand outward. Due to the matching relationship between the first arc expansion bar 51 and the second arc expansion bar 51, the first arc expansion bar 51 will also expand outward, and then the radius of the irregular circle formed by the multiple first arc expansion bars 51 and the second arc expansion bars 52 will gradually increase.

[0067] At that time, the slide bar 57 at the bottom of the first arc expansion strip 51 will pull the adjustment rod 1 541 to move outward. When the adjustment rod 1 54 moves to a certain position, it will pull the adjustment rod 2 542 to move outward, so that the trapezoidal shielding plate 54 and the fan-shaped shielding plate 55 that are close to each other gradually move away from each other, and the irradiation area surrounded by the shielding plate 54 and the fan-shaped shielding plate 55 increases, thereby reducing the shielding coverage range. By adjusting the first adjustment rod 551 and the second adjustment rod 552 on both sides of the fan-shaped shielding plate 55, the fan-shaped shielding plate 55 can be moved inward. Folding, so as to cooperate with the illumination of LED lamp 31 to achieve outlining of the skin contour of the patient with herpes zoster, and define the skin area with herpes zoster. Since the treatment area is often irregular, it cannot be cleaned after marking (the affected area is required to be kept dry during the treatment process and 3 days after treatment to achieve the best treatment effect, and a humid environment may cause pain to increase or relapse). Secondly, marking the head and face affects the patient's social interaction, and in the case of a wound surface during the blister stage of the lesion, it is impossible to mark and fix the treatment range, so a shielding mechanism is used to define the treatment range.

[0068] Then, the laser optical fiber is connected to the device through the light source port 11 provided on the laser base 1. The light source port 11 is connected to the lifting base through an optical fiber. When the optical fiber port is connected to the light source, there will be laser in the irradiation head 3 to perform laser treatment on the unobstructed skin area with herpes zoster. During the treatment, some positions that are inconvenient to irradiate can be treated by twisting the irradiation head 3. At the same time, the skin surface temperature is detected by the temperature probe 9 until a terminal reaction occurs at 42 degrees Celsius, indicating that the treatment is effective. In the early clinical experiments, the endpoint of the treatment was based on the index of increased skin surface temperature. In order to improve the stability of the treatment effect, the temperature probe 9 is designed, and the area with insufficient temperature rise can be treated additionally, which can also avoid thermal damage caused by excessive temperature.

[0069] Finally, when the treatment is completed, the irradiation head 3 can be raised by the lifting assembly 2 so that the cooling surface 82 is exposed, and the skin is cooled by the cooling surface 82 to alleviate the discomfort of the skin.

[0070] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
