[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: like Figures 1 to 8 As shown, Embodiment 1 of the present invention provides a warm low-frequency therapeutic device, comprising a therapeutic device body and a spinal treatment electrode assembly. Since the present invention focuses on the spinal treatment electrode assembly, the therapeutic device body (i.e., the main unit) has not been improved, and therefore the structure of the therapeutic device body is not described in detail. The present invention designs a spinal treatment electrode assembly specifically for spinal treatment, comprising two fixators 1, a limiting rod 2, three pressing units 3, a flexible support layer 5, and a current conducting layer 6.

[0027] The two fixers 1 are respectively adsorbed to the flat skin areas (such as under the scapula or the waist) on both sides of the patient's back through the suction cups 12, forming stable support points. The two ends of the limiting rod 2 are respectively connected to the cover bodies 11 of the two fixers 1 through the two ball hinge seats, and the ball hinge seats can realize multi-angle free adjustment between the limiting rod 2 and the cover bodies 11, so as to adapt to the back contour with different physiological curvatures.

[0028] The bottom of the shell 31 of each pressing unit 3 is fixed with a rotating sleeve 32, and the three pressing units 3 are rotatably installed on the limiting rod 2 through the rotating sleeves 32, so that each pressing unit 3 can rotate around the limiting rod 2, so that the pressing unit 3 conforms to the undulation of the back area. As shown in Figures 3 to 7 Each shell 31 of the pressing unit 3 is vertically inserted with four parallel rod bodies 33, the bottom ends of the rod bodies 33 extend to the outside of the shell 31 and are connected to the "︺" shaped pressing block 4 through the ball hinge seat, and the opening end of the pressing block 4 faces upward, which makes the bottom of the pressing block 4 have a large contact area with the flexible support layer 5, and the transition between the edge of the pressing block 4 and the flexible support layer 5 is soft. The part of each rod body 33 located in the shell 31 is fixed with a boss 34. The rod body 33 is sleeved with a first spring 35, and the two ends of the first spring 35 are respectively abutted with the boss 34 and the inner wall of the shell 31, forming an elastic buffer reset mechanism. A pressing mechanism is arranged on the shell 31, which can press the rod body 33, so that the pressing block 4 is pressed against the back.

[0029] The flexible support layer 5 is made of medical silica gel or elastomer material, and is laid on the bottom of all pressing blocks 4, and the lower part is closely attached to the current conducting layer 6. The current conducting layer 6 is made of conductive fabric or metal foil material, and is connected to the low-frequency current output end of the therapeutic instrument main machine through the connecting wire.

[0030] In use, first, the two fixers 1 are adsorbed to the flat skin on both sides of the spine, and the angle of the limiting rod 2 is adjusted so that the pressing unit 3 covers the spine. The pressing mechanism presses the pressing block 4 downward through the rod body 33, so that the flexible support layer 5 is preliminarily attached to the back contour. At the convex part of the spine, the pressing block 4 is compressed and the first spring 35 is compressed; in the concave area, the first spring 35 is released to push the rod body 33 to elongate, so that the flexible support layer 5 dynamically adapts to the undulation of the back, completely eliminates the air bubbles and gaps, and ensures the uniform distribution of current and the heat conduction efficiency. After turning on the therapeutic instrument, the current acts on the target area through the current conducting layer 6, and the treatment is carried out. The back treatment electrode assembly designed in the application solves the problem that the electrode sheet in the prior art is difficult to attach to the back area of the patient.

[0031] Embodiment two: On the basis of embodiment one, embodiment two provides a specific design of the pressing mechanism, which can realize synchronous pressing of multiple pressing blocks 4 and precise control of pressure. As shown in Figure 4and Figure 5 As shown, the pressing mechanism of the present invention is as follows: a first driven wheel 36 is rotatably mounted on the top of each rod body 33. Since the rod body 33 can move on the housing 31, the first driven wheel 36 can be regarded as a movable pulley. A second driven wheel 37 is rotatably mounted on the housing 31 between two adjacent rod bodies 33. Since the position of the second driven wheel 37 on the housing 31 remains unchanged, the second driven wheel 37 can be regarded as a fixed pulley. A reversing wheel 38 is rotatably mounted on the end of the housing 31. The starting end of the pull rope 39 is fixed to the end away from the reversing wheel 38 in the housing 31. After the pull rope 39 alternately wraps around each first driven wheel 36 and the second driven wheel 37, it passes through the reversing wheel 38 to form a composite pulley set. When the pull rope 39 on the reversing wheel 38 is tightened, the pull rope 39 will drive the rod body 33 to overcome the elasticity of the first spring 35 and move toward the pressing block 4.

[0032] In order to control the retraction and extension of the pull rope 39, the winding structure 7 designed in the present invention includes a clearance hole 72 opened on the side wall of the shell 31, and the winding roller 71 is inserted into the clearance hole 72. A knob 73 is fixed to the end of the winding roller 71 outside the shell 31, and a limit platform 75 is fixed to the end inside the shell 31. The diameter of the limit platform 75 is larger than the diameter of the clearance hole 72, so that the winding roller 71 will not escape from the clearance hole 72. The end of the pull rope 39 is wound around the winding roller 71 on the inner side of the limit platform 75. When the knob 73 is turned, the winding roller 71 rotates, winding the pull rope 39 around the winding roller 71, so that the pull rope 39 drives the rod body 33 to compress the first spring 35, causing the rod body 33 to move toward the pressing block 4, pushing the pressing block 4 against the patient's back.

[0033] To prevent the knob 73 from rotating and loosening the draw cord 39 when it is released, the present invention features a key bar 76 on the take-up roller 71 and a matching key slot 77 on the inner wall of the clearance hole 72. When the key bar 76 is engaged in the key slot 77, the take-up roller 71 cannot rotate, thus preventing the draw cord 39 from loosening. When the key bar 76 is disengaged from the key slot 77, the knob 73 can be manually rotated to tighten or loosen the draw cord 39. A second spring 74 is mounted on the take-up roller 71 between the knob 73 and the housing 31, providing a reverse return force. When the operator releases the knob 73, the second spring 74 forces the key bar 76 to engage the key slot 77, securing the take-up roller 71. When the operator presses the knob 73, the second spring 74 can be compressed and the key bar 76 can be pushed away from the key slot 77. At this time, the operator can turn the knob 73 to reel or unreel the pull rope 39, adjust the tension of the pull rope 39, and then adjust the pressing force of the pressing block 4 on the patient's spine.

[0034] by Figure 4 and Figure 5When observing as a reference, press the knob 73 to disengage the key bar 76 from the key slot 77, then rotate the knob 73 clockwise to drive the winding roller 71 to tighten the drawstring 39. Through the pulley system, all rods 33 are linked to press down toward the bottom of the shell 31, so that the pressing block 4 evenly presses down the flexible support layer 5, tightly fitting the concave area of ​​the spine. After releasing the knob 73, the second spring 74 pushes the winding roller 71 to move axially, and the key bar 76 is stuck in the key slot 77, so that the winding roller 71 cannot rotate, thereby maintaining the state of the drawstring 39. In this embodiment, the tension of the drawstring 39 is transmitted to each rod 33 during winding through the pulley system, ensuring that the pressure on different curvature areas of the spine is consistent. By fine-tuning the knob 73, the tension of the drawstring 39 can be changed, and the pressure of the pressing block 4 can be adjusted individually.

[0035] Example 3: On the basis of the first and second embodiments, the third embodiment of the present invention designs a retractable limit rod 2. Figure 8 As shown, the limiting rod 2 comprises a rod sleeve 21 and two inner rods 22 inserted into the sleeve 21 from either end. A gear 23 is rotatably mounted in the center of the sleeve 21. The ends of the two inner rods 22 inserted into the sleeve 21 are provided with teeth 24 that mesh with the gears 23 on both sides. This allows the inner rods 22 on either side to move symmetrically via the gears 23 during extension and retraction. The three pressing units 3 are mounted on the sleeve 21, thus maintaining the pressing units 3 in the center of the limiting rod 2. Manually pulling the two inner rods 22 simultaneously adjusts their extended length to accommodate the spinal dimensions of patients with varying body widths.

[0036] A heating layer is embedded between the flexible support layer 5 and the current conducting layer 6. The serpentine-shaped graphene heating wire inside the heating layer is connected to the temperature control system of the therapeutic device body to achieve constant temperature control within the range of 36 degrees Celsius to 45 degrees Celsius.

[0037] During use, the length of the limiting rod 2 is adjusted so that the two fixators 1 are positioned near the patient's shoulder blades. After attaching the fixators 1 to the patient's body, the knob 73 is pressed and tightened to allow the pressing block 4 to adapt to the spinal curve. Upon activation of the therapeutic device, the graphene heating layer heats up rapidly and evenly, creating a synergistic effect with the electrotherapy, significantly promoting local blood circulation and tissue repair. The retractable limiting rod 2 expands the patient population for whom this invention is applicable.

[0038] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
