Description

Technical Field

[0001] This invention relates to the field of laser therapy technology, and in particular to a laser magnetic stimulation therapy device based on the synergy of alternating magnetic field and phototherapy. Background Technology

[0002] Alternating magnetic fields can penetrate the skin and bones painlessly and non-invasively, reaching a depth of up to 10 centimeters. They directly stimulate deep nerves and muscles, relieving pain, promoting muscle contraction, and aiding in functional recovery. Laser therapy, on the other hand, primarily targets superficial tissues and cells, improving local blood circulation, eliminating inflammation, and accelerating tissue repair and regeneration.

[0003] Currently, laser and magnetic stimulation typically employ two independent treatment heads, which must be placed sequentially or separately on either side of the treatment area. This results in inconsistent application sites for the laser and magnetic field, limiting their synergistic effect. Furthermore, the dual-head positioning method is cumbersome, time-consuming, and difficult to deploy simultaneously in confined spaces. In addition, the irradiation area of ​​existing laser treatment heads is difficult to adjust, easily covering non-treatment areas and causing unnecessary irradiation; while the magnetic field itself is invisible, making it difficult for the operator to visually judge its distribution and direction, affecting the precise positioning of magnetic stimulation.

[0004] Therefore, a laser magnetic stimulation therapy device based on the synergy of alternating magnetic field and phototherapy is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems that the irradiation area of ​​existing laser treatment heads is difficult to adjust, easily covering non-treatment areas and causing unnecessary irradiation; and that the magnetic field itself is invisible, making it difficult for the operator to intuitively judge its distribution and direction, affecting the accurate positioning of magnetic stimulation. Therefore, this invention proposes a laser magnetic stimulation therapy device based on the synergy of alternating magnetic field and phototherapy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A laser magnetic stimulation therapy device based on the synergy of alternating magnetic field and phototherapy includes a mobile control cabinet carrying a control module. The mobile control cabinet is connected to the laser therapy device body via a multi-degree-of-freedom control arm. The laser therapy device body includes an outer holding shell. Inside the outer holding shell, from top to bottom, are arranged a imaging component, a magnetic field adjustment component, a laser heat dissipation component, and a controllable laser adjustment component. The outer holding shell includes an outer cover that is rotatably connected to the multi-degree-of-freedom control arm. The outer cover is connected to a lower end cover via an internal compression connector. The controllable laser adjustment component includes an annular laser output disk installed above the lower end cover. The lower end cover is provided with a light-transmitting port for laser transmission, and a light-blocking adjustment ring is provided on the lower end cover for adjusting the opening and closing of the light-transmitting port. The laser heat dissipation assembly includes a heat exchange mounting plate disposed on the inner wall of the outer casing, a magnetohydrodynamic heat exchange liquid plate disposed above the heat exchange mounting plate, and a cold light layer disposed inside the heat exchange mounting plate with the light of the cold light layer facing upward.

[0007] As a preferred embodiment, the light-blocking adjustment ring consists of an inner ring and an outer ring, which are connected by an embedded sliding member. The outer wall of the outer ring is provided with a serrated layer. A knob post is rotatably provided on the lower end cover. The end of the knob post is provided with a serrated disc that meshes with the serrated layer. A notch is provided on the outer cover for the knob post to move.

[0008] As a preferred embodiment, the developing assembly includes a projection end cap installed on the top of the outer casing, a developing magnetic fluid is disposed inside the magnetic flux heat exchange liquid tray, and the cold light layer emits light upward to project the state of the developing magnetic fluid onto the projection end cap.

[0009] As a preferred embodiment, the magnetic field adjustment assembly includes a track plate rotatably mounted on the inner wall of the outer casing and arranged opposite each other. Two sets of oppositely arranged electromagnetic components are slidably connected to the track plate. A rotary motor is installed inside the track plate. An adjusting stud is connected to the output end of the rotary motor. An adjusting disc is threadedly connected to the outer wall of the adjusting stud. The adjusting disc is connected to the electromagnetic components through an adjusting rod and is used to adjust the position of the electromagnetic components.

[0010] As a preferred embodiment, the track plate is transparent and has a limiting groove on it, and the bottom of the electromagnetic component is provided with a limiting slider that is slidably connected to the limiting groove.

[0011] As a preferred embodiment, the track plate is rotatably connected to the magnetohydrodynamic heat exchange liquid plate in the middle via a rotating shaft, a knob is provided on one side of the track plate, and a sliding opening for the knob to be rotated is provided on the outer cover.

[0012] As a preferred embodiment, the internal compression connector includes a sliding groove formed on the outer side wall of the outer cover, and a limiting seat adapted to the sliding groove is provided on the outer side wall of the lower end cover. The limiting seat is located inside the sliding groove and is connected to the sliding groove by a compression spring.

[0013] As a preferred embodiment, a contact ring is provided at the bottom of the lower end cover, and a rolling ball is provided at the bottom of the contact ring for moving the laser therapy device body.

[0014] As a preferred embodiment, the embedded slider includes an annular opening on the inner wall of the outer ring, and an insert block located within the annular opening is provided on the outer wall of the inner ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention integrates the alternating magnetic field generating component and the laser output component into the same treatment head. Single-point positioning and synchronous output are achieved through a multi-degree-of-freedom control arm, solving the problem of traditional equipment requiring two independent treatment heads for step-by-step operation and separate placement. This allows the magnetic field acting on deep tissues and the laser acting on superficial tissues to form a spatiotemporal synergy in the same lesion area, enhancing the comprehensive efficacy of analgesia, anti-inflammation, and tissue repair. It significantly avoids the cumbersome process of positioning two treatment heads separately, and is especially suitable for narrow treatment sites such as the paravertebral region and joint spaces, significantly reducing the difficulty of operation and improving treatment efficiency.

[0016] 2. This invention, by setting up a light-blocking adjustment ring composed of an inner ring and an outer ring, in conjunction with a knob post and a helical gear transmission mechanism, can precisely control the opening and closing size of the light-transmitting port. The operator can flexibly adjust the laser coverage area according to the lesion area, avoid laser irradiation of healthy tissue, achieve "targeted" phototherapy, and thus reduce the risk of unnecessary tissue exposure.

[0017] 3. This invention utilizes the interaction between the imaging magnetic fluid within the magnetohydrodynamic heat exchanger and the upward projection of light from the cold light layer to project the invisible magnetic field distribution onto the top projection cap in real time. The operator can directly observe the range, shape, and direction of the magnetic field with the naked eye, changing the traditional "blind" positioning method of magnetic stimulation, significantly improving the accuracy of magnetic field positioning, ensuring the magnetic field reaches the lesion directly, and reducing the impact on surrounding normal tissues.

[0020] 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.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example, refer to Figures 1 to 7 A laser magnetic stimulation therapy device based on the synergy of alternating magnetic field and phototherapy includes a mobile control cabinet 1 carrying a control module. The mobile control cabinet 1 is connected to the laser therapy device body through a multi-degree-of-freedom control arm 2. The laser therapy device body includes an outer holding shell. Inside the outer holding shell, from top to bottom, are arranged a imaging component, a magnetic field adjustment component, a laser heat dissipation component, and a controllable laser adjustment component. It should be noted that the imaging component projects the magnetic field state within the magnetohydrodynamic heat exchanger plate 9, allowing the user to clearly understand the distribution of the magnetic field. This enables more precise positioning of the area to be treated using the magnetic field, thereby reducing the impact of the alternating magnetic field on the position of other areas and allowing the treatment to directly reach the lesion.

[0024] The outer housing includes an outer cover 3 that is rotatably connected to the multi-degree-of-freedom control arm 2. The bottom of the outer cover 3 is hollowed out. The outer cover 3 is connected to a lower end cover 4 through an internal compression connector. Further, the internal compression connector includes a sliding groove 19 formed on the outer side wall of the outer cover 3. The outer side wall of the lower end cover 4 is provided with a limiting seat 20 that is adapted to the sliding groove 19. The limiting seat 20 is located in the sliding groove 19 and is connected to the sliding groove 19 through a compression spring.

[0025] The further advantage of the above is that by telescopically connecting the lower end cover 4, which is in contact with the skin, to the outer cover 3, the lower end cover 4 will retract inward into the outer cover 3 during downward pressure. This allows the magnetic field strength to be controlled by changing the distance between the magnetic field and the skin, and also achieves heat dissipation for the ring laser output disk 5.

[0026] The controllable laser adjustment component includes an annular laser output disk 5 installed above the lower end cover 4, a light-transmitting port 6 for laser transmission on the lower end cover 4, and a light-blocking adjustment ring 7 for adjusting the opening and closing of the light-transmitting port 6 on the lower end cover 4. The light-blocking adjustment ring 7 consists of an inner ring 701 and an outer ring 702. The inner ring 701 and the outer ring 702 are connected by an embedded sliding piece. The outer side wall of the outer ring 702 is provided with a serrated layer 11. A knob post 10 is rotatably provided on the lower end cover 4. The end of the knob post 10 is provided with a serrated disc that meshes with the serrated layer 11. A notch is provided on the outer cover 3 for the knob post 10 to move.

[0027] It should be noted that when it is necessary to control the laser coverage area according to the size of the treatment site, the knob column 10 can be rotated externally to make the inclined toothed plate connected to its end rotate, thereby changing the position of the light-blocking adjustment ring 7. This causes the adapter hole on the light-blocking adjustment ring 7 to be misaligned with the light-transmitting port 6, thereby achieving the effect of covering and blocking the light-transmitting port 6.

[0028] Furthermore, the embedded slider includes an annular slot 703 formed on the inner wall of the outer ring 702, and an embedded block 704 located in the annular slot 703 is provided on the outer wall of the inner ring 701. By adopting the embedded slider, sliding can be achieved between the outer ring 702 and the inner ring 701, so as to achieve the effect of controlling the rotation range separately.

[0029] The laser heat dissipation assembly includes a heat exchange mounting plate 8 disposed on the inner wall of the outer casing 3, a magnetofluid heat exchange liquid plate 9 disposed above the heat exchange mounting plate 8, and a cold light layer disposed inside the heat exchange mounting plate 8 with the light of the cold light layer facing upward.

[0030] It should be noted that the heat exchange mounting plate 8 is located above the annular laser output disk 5. When it comes into contact with the annular laser output disk 5 (the internal compression connector allows it to extend and retract), it can effectively cool the annular laser output disk 5 through the liquid in the magnetohydrodynamic heat exchange liquid disk 9.

[0031] Furthermore, the developing assembly includes a projection end cap 22 mounted on the top of the outer casing 3, a developing magnetic fluid is disposed inside the magnetic flux heat exchange liquid tray 9, and the cold light layer emits light upward to project the state of the developing magnetic fluid onto the projection end cap 22.

[0032] The cold light layer is an LED cold light source array that emits uniform cold light upwards. The light passes through the magnetohydrodynamic heat exchange liquid plate 9 and the developing magnetohydrodynamic fluid inside it in sequence. Under the action of the alternating magnetic field generated by the magnetic field adjustment component, the magnetic particles inside the developing magnetohydrodynamic fluid are arranged along the direction of the magnetic field lines, forming a light transmittance difference pattern corresponding to the magnetic field distribution pattern.

[0033] Furthermore, the magnetic field adjustment assembly includes a track plate 12 rotatably mounted on the inner wall of the outer casing 3 and arranged opposite to each other. Two sets of oppositely arranged electromagnetic components 13 are slidably connected on the track plate 12. The electromagnetic components 13 control the magnitude of the magnetic force through current. A rotary motor 14 is installed inside the track plate 12. The rotary motor 14 is a small motor, which is existing technology and will not be described in detail here. An adjusting stud 15 is connected to the output end of the rotary motor 14. An adjusting disc 16 is threadedly connected to the outer wall of the adjusting stud 15. The adjusting disc 16 is connected to the electromagnetic component 13 through an adjusting rod 17 and is used to adjust the position of the electromagnetic component 13. The two ends of the adjusting rod 17 are connected by shaft holes to achieve rotational connection.

[0034] It should be noted that the rotary motor 14 is used to control the adjustment stud 15 to rotate, thereby controlling the adjustment disk 16 to move up and down. When the adjustment disk 16 moves up and down, it will simultaneously drive the electromagnetic components 13 located on both sides of the track plate 12 to change the spacing, thereby changing the magnetic field circumference distribution.

[0035] Furthermore, the track plate 12 is transparent and has a limiting groove. The bottom of the electromagnetic component 13 is provided with a limiting slider that is slidably connected to the limiting groove. The middle of the track plate 12 is rotatably connected to the magnetohydrodynamic heat exchange liquid plate 9 through a rotating shaft. A toggle button 18 is provided on one side of the track plate 12, and the outer cover 3 is provided with a toggle opening for the toggle button 18 to rotate.

[0036] When it is necessary to adjust the orientation of the magnetic field, the dial 18 can be turned to rotate the track plate 12 and the electromagnetic component 13 above it, thereby changing the position of the magnetic poles on both sides and controlling the direction of the magnetic field.

[0037] Furthermore, a contact ring 21 is provided at the bottom of the lower end cover 4, and a rolling ball is provided at the bottom of the contact ring 21 for moving the laser therapy device body. The contact ring 21 is made of medical silicone material to ensure safety.

[0038] When using this invention, the laser therapy device body is moved above the patient's treatment area by the multi-degree-of-freedom control arm 2, the angle of the outer cover 3 is adjusted so that the lower cover 4 is in initial contact with the skin, the knob column 10 is rotated, and the light-blocking adjustment ring 7 is driven by the oblique tooth layer 11. According to the treatment needs, the opening size of the light-transmitting port 6 is adjusted to control the laser irradiation range and achieve the effect of precise laser treatment.

[0039] Start the imaging component and cold light layer, observe the magnetohydrodynamic projection status displayed on the projection end cap 22, and fine-tune the multi-degree-of-freedom control arm 2 according to the magnetic field distribution displayed on the projection to ensure that the magnetic field projection range coincides with the lesion location. By observing the projection, the operator can intuitively understand the current magnetic field distribution range and shape, thereby adjusting the position of the device to make the magnetic field accurately cover the lesion and reduce interference with the surrounding healthy tissues.

[0040] At this point, turn knob 18 to rotate track plate 12 and observe the change in the direction of the magnetic field in the projection until the direction of the magnetic field lines matches the treatment requirements. Then, start rotary motor 14 to control the rotation of adjusting stud 15, causing adjusting disc 16 to rise and fall, which in turn drives electromagnetic component 13 to adjust the spacing until the magnetic field coverage meets the treatment area requirements. The current of electromagnetic component 13 is adjusted by the control module to change the basic magnetic force. During the treatment process, gently press the outer cover 3 up and down repeatedly, and use the internal compression connector to retract the lower cover 4 inward, shortening the distance between the magnetic field source and the lesion, thus achieving fine-tuning of the intensity.

[0041] After confirming that the magnetic field and laser parameters are set, the alternating magnetic field and laser output are started through the control module. During the treatment, the imaging status of the projection end cap 22 is continuously observed to ensure that the magnetic field does not shift; at the same time, the operating status of the equipment is observed.

[0042] The above description is only a preferred embodiment of the present invention, but 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 inventive concept of the present invention, should be covered within the scope of protection of the present invention.
