[0002] Medium-frequency electrical stimulation therapy, a key approach in rehabilitation medicine, is widely used for neuromuscular function restoration, local pain relief, and tissue repair. In clinical practice, treatment effectiveness depends significantly on precise electrode placement, secure adhesion, and the proper relative placement of multiple electrodes. Currently, medical professionals often rely on experience to manually apply electrodes to the corresponding areas on the patient's body, lacking standardized standards or auxiliary positioning devices. This method suffers from poor repeatability of placement, asymmetric electrode spacing, and inefficient manual measurement. Furthermore, rapid adjustment and repositioning are not possible in certain treatments requiring multi-point placement. Furthermore, due to the wide range of patient body shapes, traditional application methods struggle to adapt to diverse anatomical features, leading to warping, dislodgment, and uneven current stimulation, which can compromise treatment effectiveness. While some improved devices attempt to secure electrodes using adjustable brackets or auxiliary straps, they generally lack systematic spatial positioning scales, visual indicator components, and flexible adjustment mechanisms, failing to meet clinical requirements for efficient, accurate, and secure electrode positioning. Therefore, how to provide a medium-frequency therapeutic electrode positioning device that is easy to operate, flexible in structure, accurate in positioning, and highly adaptable is one of the urgent problems to be solved in current rehabilitation therapy equipment.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 8 As shown, the present invention provides a multifunctional medium frequency treatment electrode positioning device for rehabilitation, which includes a base 1, a column 3, an adjustable arm assembly 4, a positioning guide rail assembly 5, a main positioning assembly 6 and an adjustable electrode mounting assembly 7.

[0023] The base 1 serves as the foundation for the entire device. Multiple universal wheels 2 are evenly distributed throughout its base, allowing medical personnel to adjust the device's position based on treatment needs. The universal wheels feature built-in locking mechanisms to prevent slipping. A column 3 is vertically fixed to the base 1, supporting the adjustable arm assembly 4 and serving as the support point for the entire superstructure.

[0024] The adjustable arm assembly 4 is mounted on the top of the column 3 by a rotational connection. The assembly includes a plurality of adjustable arms 8, each of which is hingedly connected by a single-axis rotation joint structure. Specifically, each adjustable arm is provided with a joint hole at the head and a shaft mounting ear seat at the tail. Adjacent adjustable arms are rotatably connected by a pin. A knob screw is provided on the outside of each joint. By rotating the screw, the corresponding shaft can be locked to fix the angle of each arm. By combining multiple adjustable arms in series, the operator can adjust the extension direction and posture of the arm in space, thereby adjusting the angle and position of the positioning guide assembly 5 below to meet the clinical needs of different treatment sites.

[0025] The positioning guide rail assembly 5 is installed at the front end of the adjustable arm 8 at the end, and is used to carry the electrode layout structure and the main positioning device. The assembly includes a longitudinal guide rail seat 11, an outer guide rail 12, a longitudinal positioning ruler 16, a longitudinal guide rod 17 and a longitudinal guide block 18. The outer guide rail 12 is installed on the top of the longitudinal guide rail seat 11 by a fastening connection method, and is used to support the sliding components and the ruler system. The longitudinal guide rod 17 is arranged on the lower side of the outer guide rail 12, and is used to guide the longitudinal guide block 18 to slide. The longitudinal guide block 18 is a strip-shaped structure that can slide along the longitudinal guide rod 17 in the front and rear directions, and can be stopped at any position by a locking device. A longitudinal positioning ruler 16 is provided on the side wall of the outer guide rail 12. It is a scale bar with equal intervals, which can be used in conjunction with the mark or observation hole on the longitudinal guide block 18 to achieve precise adjustment and repeated arrangement of the longitudinal electrode position.

[0026] The main positioning component 6 is installed on the front side of the outer guide rail 12, and includes a positioning guide seat 13, a positioning arm 14 and a positioning end piece 15. The positioning guide seat 13 and the outer guide rail 12 are in a sliding connection relationship, and can move left and right along the guide rail and be fixed in position by threaded locking. The positioning arm 14 is fixedly connected to the front end of the positioning guide seat 13, and a length scale is provided on its outer side to facilitate observation of the positioning extension distance. The positioning end piece 15 is fixedly installed on the end of the positioning arm 14, and a layer of flexible gasket is provided on the contact surface close to the patient, which is preferably made of silicone to avoid the positioning end piece from directly contacting the skin and causing discomfort, thereby enhancing safety of use. The main positioning component can be used to refer to obvious anatomical landmarks on the patient's body surface (such as scapula, anterior superior iliac spine, etc.) to assist in determining the reference point for electrode layout, thereby improving positioning accuracy and repeatability.

[0027] The adjustable electrode mounting assembly 7 is installed at the bottom of the positioning guide rail assembly 5, and its structure includes a transverse positioning ruler 19, a transverse guide rail seat 20, a transverse guide rod 21, a plurality of transverse guide blocks 22, an indicator needle 23, an insert block 24 and an electrode sheet 25. The transverse guide rail seat 20 is fixed to the bottom surface of the outer guide rail 12 by screws, and the transverse guide rod 21 is horizontally arranged on the transverse guide rail seat 20 to guide the transverse guide block 22 to slide left and right. Multiple transverse guide blocks 22 can slide independently, and an indicator needle 23 is provided at the upper end of each transverse guide block 22 to cooperate with the transverse positioning ruler 19 to realize transverse coordinate reading. A socket is provided at the front of the transverse guide block 22, and the insert block 24 is fixedly connected to the socket after being inserted into the socket. A slot structure is provided above the insert block 24 for installing the electrode sheet 25. The top of the electrode sheet 25 is provided with an electrode terminal for connecting the output cable of the medium frequency therapeutic device. The bottom is a flexible conductive bonding layer, which is coated with conductive silicone grease or medical conductive gel to enhance skin conductivity and comfort and ensure the electrode stimulation effect.

[0028] In summary, the entire device achieves multi-directional and multi-level adjustable control through the coordination of the base, column, arm assembly and guide rail system. The connection relationship between each module is clear, the structure is compact, and the operation is convenient. It can adapt to different patient body shapes and treatment needs, and has good adaptability and clinical promotion value.

[0029] like Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the multiple adjustable arms 8 of the present invention are connected by a single-axis rotation joint structure. The head of each adjustable arm 8 is provided with a circular joint hole, and the tail is provided with a shaft mounting ear seat for inserting a pin shaft. The adjacent adjustable arms 8 are rotatably connected by inserting a rotating pin shaft between the joint hole and the ear seat, which ensures that the device can rotate smoothly in multiple directions. In order to facilitate the fixation of the rotation angle of each section of the adjustable arm 8, a knob screw is provided on the outside of each joint structure. The screw can be tightened manually to tighten the pin shaft in the joint, thereby achieving angle locking. After the operator has adjusted the arm to the required angle, he only needs to manually tighten the knobs of each section to fix the posture of the entire arm, thereby ensuring the stability and consistency of subsequent positioning.

[0030] This structural form is both simple and reliable, and easy to manufacture. The axis of rotation is clearly fixed, and the rotation direction is confined to a single plane. This helps achieve controllable positioning of the treatment electrode path and prevents spatial posture disturbances from interfering with positioning accuracy. When multiple adjustable arms are combined in series, the overall height, reach, and rotation angle of the arms can be flexibly adjusted to suit the varying needs of different patients, such as height and body type, or the spatial location of the treatment area, enhancing the device's clinical adaptability.

[0031] In order to further expand the degree of freedom of adjustment and precisely control the angle adjustment of the guide rail assembly, a longitudinal guide rail seat 11 and a telescopic connection structure are provided in the positioning guide rail assembly 5. A section of an outer arm 10 with a hollow long strip structure is fixedly connected above the longitudinal guide rail seat 11. A guide cavity is provided inside the outer arm 10, and an inner arm 9 of matching size is slidably inserted therein. The inner arm 9 can freely extend and slide axially in the outer arm 10. By adjusting the extended length, the displacement of the guide rail assembly in the front-to-back or up-and-down directions in space can be achieved. In order to ensure that the inner arm 9 is stable in the preset position, a threaded hole is provided on the side wall of the outer arm 10, and a locking screw is installed in the threaded hole. When the inner arm 9 is extended to the target position, the screw can be tightened to fix it to prevent sliding.

[0032] The present invention further provides a ball hinge structure between the distal end of the inner arm 9 and the end of the adjustable arm 8, for providing a multi-directional rotation adjustment function to compensate for the spatial directional limitation of the single-axis rotation connection. The ball hinge structure includes a ball head provided at the end of the inner arm 9 and a ball sleeve installed at one end of the adjustable arm 8. The ball head is preferably made of metal or high-strength plastic, and its outer surface is processed as a standard spherical surface to achieve good contact and fit with the ball sleeve. The ball sleeve is an integrally formed open-type embracing structure, and a spherical limiting cavity is provided inside it, which fits the spherical surface of the ball head. Through the spherical sliding fit between the ball head and the ball sleeve, the guide rail assembly can achieve omnidirectional posture adjustment, including pitching up and down, swinging left and right, and oblique rotation and other degrees of freedom adjustment.

[0033] To ensure controllable rotation angle and reliable locking, a positioning screw is installed on the outside of the ball sleeve, perpendicular to the sleeve opening. After adjusting the ball head's posture, the operator tightens the positioning screw, pressing the sleeve inward against the ball head, thereby clamping and locking the ball joint and effectively preventing angular deviation during use. This structure ensures that the guide rails for the treatment electrodes can be adjusted quickly and accurately, ensuring reliable fixation, even with changes in patient posture and treatment areas, improving clinical efficiency.

[0034] Overall, the above structure uses the triple degree of freedom combination of "single-axis rotation + axial extension + ball head rotation" to enable the positioning guide rail assembly of the present invention to be flexibly adjusted in three-dimensional space, accurately aligned with the patient's target area, and quickly locked through the knob and screw system, ensuring the convenience and safety of operation, and meeting the diverse positioning needs in complex treatment scenarios.

[0035] Specifically, the top of the longitudinal guide rail seat 11 is fixedly connected to an outer guide rail 12. The outer guide rail 12 is a guide rail extending laterally, and its cross-section is a "U"-shaped or "T"-shaped structure, which is used to limit the sliding direction and provide a stable guide base. The main positioning component 6 is arranged on the front side of the outer guide rail 12, and is mainly used to achieve accurate positioning of the patient's body surface feature points. The positioning guide seat 13 is an integrally formed sliding structure, and a slide groove is provided at the bottom thereof, which slides with the outer guide rail 12 and can move back and forth in the length direction of the outer guide rail 12. The positioning guide seat 13 is provided with a threaded hole and is threadedly connected with a locking screw. After the operator moves the positioning guide seat 13 to the target position, the screw can be tightened to fix it on the outer guide rail 12, thereby avoiding position displacement during use.

[0036] A positioning arm 14 is provided on the front side of the positioning guide 13. The positioning arm 14 is a slender, strip-shaped member with one end fixedly connected to the positioning guide 13 and the other end extending forward to support the positioning end piece 15. The positioning arm 14 is printed with longitudinal scale lines that can be used to assist in adjusting the positioning position by reference to the patient's anatomical landmarks or the physician's preset values. The positioning end piece 15 is mounted at the distal end of the positioning arm 14. Its end surface has a soft arc structure and is sized to fit the adult shoulder. It is typically used to fit against the surface contour of the patient's shoulder area and calibrate the spatial reference position of the electrode layout by fitting against bony shoulder landmarks (such as the acromion and the inner edge of the scapular spine). A flexible gasket is provided on the end surface of the positioning end piece 15 on the side closest to the positioning arm 14. This gasket is made of medical-grade silicone material and has soft, skin-friendly, non-slip, and cushioning properties. It provides a good tactile feel when placed against the patient's shoulder skin, avoiding discomfort or local tenderness caused by direct contact with a hard end piece, and improving fixation stability and comfort during repeated use.

[0037] During use, the operator moves the positioning guide seat 13 along the outer guide rail 12 to the appropriate position according to the patient's body shape and treatment area requirements, performs rough positioning through the scale lines and shoulder anatomical landmarks, tightens the locking screws to complete the guide seat fixation, and then adjusts the extension length of the positioning arm 14 so that the positioning end piece 15 is close to the patient's shoulder surface, finally completing the establishment of the body surface positioning reference.

[0038] Furthermore, in the adjustable electrode mounting assembly 7, the cross guide block 22 is a square or rectangular structure, on which a socket is provided for plugging and matching with the plug block 24. The plug block 24 is a flat structural part, and after its bottom is inserted into the socket in the cross guide block 22, a snap-on locking is achieved through a positioning groove or a limiting protrusion to ensure that the connection is firm and not loose. The upper surface of the plug block 24 is provided with a recessed slot structure for embedding the electrode sheet 25. The slot size matches the shape of the electrode sheet, and can achieve stable embedding. The top of the electrode sheet 25 is provided with an electrode terminal for connecting to the output circuit of the medium frequency therapeutic instrument; the bottom of the electrode sheet 25 is provided with a flexible conductive bonding layer, which is made of a skin-friendly base material, and the surface is pre-coated with conductive silicone grease or medical conductive gel. It has good conductivity and adhesion, and can form a stable electrical contact when attached to the patient's skin, effectively improving the electrical stimulation effect.

[0039] Through the above-mentioned structural arrangement, the main positioning component and the adjustable electrode mounting component cooperate with each other to achieve surface anatomical positioning, accurately control the application position and direction of the electrode sheet, ensure the repeatability and accuracy of the treatment plan, and significantly improve the clinical effect and operational efficiency of rehabilitation medium-frequency treatment.

[0040] When using the device, ① push the base 1 to the treatment area via the universal wheel 2, and step on the brake device to stabilize the base 1; ② adjust the rotation angle of each section of the adjustable arm 8 in the adjustable arm support assembly 4 to make the positioning guide rail assembly 5 roughly align with the area above the patient's shoulder, and complete the rough positioning by turning the knob screw; ③ then operate the main positioning assembly 6, slide the positioning guide seat 13 along the outer guide rail 12, and according to the actual surface characteristics of the patient, accurately affix the positioning end piece 15 to the patient's shoulder anatomical reference point, rely on the scale line on the positioning arm 14 and the longitudinal positioning ruler 16 to achieve auxiliary comparison and positioning, and fix the positioning guide seat 13 by the locking screw. At this time, the spatial reference datum setting of the entire system is completed; ④ then confirm the reference point according to the positioning end piece 15 ⑤ In the adjustable electrode mounting assembly 7, according to the set layout method, slide the cross guide block 22 on the cross guide rod 21 to the target position, complete the calibration with the horizontal positioning ruler 19 and the indicator needle 23, insert the plug block 24 and install the electrode sheet 25 in the slot, making sure that the terminal is facing up and the bottom conductive bonding layer is facing down and attached to the skin. If necessary, apply conductive silicone grease or medical gel to enhance the conductive effect; ⑥ Finally, connect the output line of the treatment instrument to the electrode terminal of the electrode sheet 25. After completing the electrode layout and adjustment, the medium frequency electrical stimulation treatment program can be started.
