[0035] like Figure 1 、 2As shown in Figures 3 and 4, a slide 10 is provided at the center of the lower inner wall of the slide 2, and the adjustment structure 3 includes a frame 305. The lower end face of the frame 305 inside the slide 10 is fixedly connected with a connecting seat 315 at both ends.

The center of one side wall of the first bracket 306 is fixedly connected with a first servo motor 304. The output end of the first servo motor 304 passes through the first bracket 306 and is passed into the interior of the first bracket 306, and the end is fixedly connected with a first worm 307. The lower end face of the connecting plate 301 at the rear end of the first worm 307 is rotatably connected with a first worm gear 308 which is meshed with the first worm 307. The upper end of the first worm gear 308 passes through the lower end face of the connecting plate 301, the slide 10 and the lower end face of the frame 305 in sequence and is passed to the frame 30 5, and the end is fixedly connected to a rack 311.

The two movable plates 310 are respectively fixedly connected to the two first mounting frames 4.

The first worm 307 drives the first worm gear 308 to rotate, and the first worm gear 308 drives the gear 309 to rotate. During the rotation process of the gear 309, the two racks 311 are simultaneously moved toward the center position, thereby driving the two movable plates 310 to move toward the center position synchronously, driving the two first mounting frames 4 and the two second mounting frames 5 toward the position of the bed body 1, so that the two extrusion treatment structures 9 are fitted to the patient's pelvic position.

[0036] A third limit block 314 is fixedly connected to one end surface of the two movable plates 310 close to the gear 309, and a second limit block 313 and a first limit block 312 are fixedly connected to one end surface of the two movable plates 310 away from the rack 311 to prevent the two racks 311 and the gear 309 from falling off.

[0037] A first protective shell 302 is fixedly connected to the lower end surface of the connecting plate 301 outside the first servo motor 304, the first bracket 306, the first worm 307 and the first worm gear 308. The lower end of the first protective shell 302 is fixedly connected to the first cover plate 303 by screws to prevent external dust or foreign matter from affecting the drive.

[0038] like Figure 1 、 2As shown in , 3, 5 and 6, taking the lifting structure 8 on one side as an example, the lifting structure 8 includes three sliding grooves 802, which are arranged front and back and opened on one end surface of the first mounting frame 4 close to the bed body 1. A first slider 803 is provided inside the sliding groove 802 at the center position, and a second slider 804 is provided inside the sliding groove 802 at the front and rear ends. The first slider 803 and the two second sliders 804 are fixedly connected to one end surface of the second mounting frame 5, and the interiors of the two sliding grooves 802 at the lower ends of the two second sliders 804 are fixedly connected to the upper end surface of the second mounting frame 5. The two screw rods 805 are rotatably connected, and the two screw rods 805 respectively pass through the lower end surfaces of the two second sliders 804 to the upper end surface of the first mounting frame 4, and a base plate 801 is provided at the end. The upper end surface of the base plate 801 located at the upper end of the two screw rods 805 is rotatably connected to the synchronous wheel 812. The two synchronous wheels 812 pass through the upper end surface of the base plate 801 to the lower end of the base plate 801, and the ends are fixedly connected to the two screw rods 805. The outer side of the two synchronous wheels 812 is provided with a synchronous belt 813. The synchronous wheel 81 is located at the front. A second bracket 808 is fixedly connected to the upper end surface of the front end substrate 801, and a second servo motor 809 is fixedly connected to a side wall of the second bracket 808. The output end of the second servo motor 809 passes through the side wall of the second bracket 808 and is connected to the interior of the second bracket 808. A second worm 810 is fixedly connected to the end of the second worm 810. A second worm wheel 811 is provided at the rear end of the second worm 810 and meshes with the second worm 810. The second worm wheel 811 is fixedly connected to a synchronous wheel 812 at the front. By controlling the second servo motor 80 9 is started, the second servo motor 809 drives the second worm 810 to rotate, the second worm 810 drives the second worm wheel 811 to rotate, thereby driving the synchronous wheel 812 at the front to rotate, and the synchronous wheel 812 at the rear is driven to rotate synchronously through the synchronous belt 813, so that the lead screw 805 rotates synchronously. Since the outer threads of the four lead screws 805 are arranged in the same way, the two second servo motors 809 are controlled to run synchronously, so that the two second mounting frames 5 move up and down along the six sliding slots 802 to adjust the positions of the two extrusion treatment structures 9.

[0039] A second protective shell 806 is fixedly connected to the upper end surface of the outer substrate 801 of the second bracket 808, the second servo motor 809, the second worm 810, the second worm gear 811, the two synchronous wheels 812 and the synchronous belt 813. The upper end surface of the second protective shell 806 is fixedly connected to the second cover plate 807 by screws to prevent external dust or foreign matter from affecting the drive.

[0040] The four electrodes 905 are divided into two positive electrodes and two negative electrodes. The two positive electrodes are set inside one of the extrusion blocks 902, and the two negative electrodes are set inside the other extrusion block 902, forming a cross current field covering the pelvic area.

[0041] The two first mounting frames 4 , the two second mounting frames 5 , the two magnetorheological elastomer dampers 6 and the two extrusion treatment structures 9 are all symmetrically arranged with the bed 1 as the axis, so as to facilitate treatment of the patient lying on the bed 1 .

[0042] Working principle: When in use, the patient lies on the bed 1, and the patient's pelvic position is monitored by the monitor 906. The monitor 906 identifies the position of the marker point through the computer vision algorithm, and calibrates the relationship between its own perspective and the coordinate system of the bed 1 in real time. This is a commonly used technical means in existing monitoring systems and will not be described in detail here. Then, according to the patient's pelvic position, the hydraulic cylinder 11 is controlled to extend and retract. The hydraulic cylinder 11 pushes the frame 305 to slide back and forth inside the slide 2. Since a graphene layer is provided on the surface of the frame 305, the resistance caused by friction is reduced. Then, by controlling the second servo motor 809 to start, the second servo motor 809 drives the second servo motor 809 to drive the second servo motor 809 to start. The rod 810 rotates, and the second worm 810 drives the second worm wheel 811 to rotate, thereby driving the synchronous wheel 812 at the front to rotate, and the synchronous wheel 812 at the rear is driven to rotate synchronously through the synchronous belt 813, so that the screw rod 805 rotates synchronously. Since the outer threads of the four screw rods 805 are arranged in the same way, the two second servo motors 809 are controlled to run synchronously, so that the two second mounting frames 5 move up and down along the six sliding grooves 802, adjust the position of the two extrusion treatment structures 9, and accurately position the two extrusion treatment structures 9 to the patient's pelvic position, so as to facilitate the positioning of the patient's pelvic position according to the different body shapes of the patients and the position of the patients lying on the bed.

[0043] Then, the first servo motor 304 is controlled to start, and the first servo motor 304 drives the first worm 307 to rotate. The first worm 307 drives the first worm gear 308 to rotate, and the first worm gear 308 drives the gear 309 to rotate. During the rotation of the gear 309, the two racks 311 move toward the center position at the same time, thereby driving the two movable plates 310 to move toward the center position synchronously, driving the two first mounting frames 4 and the two second mounting frames 5 toward the position of the bed 1, so that the two extrusion treatment structures 9 fit the patient's pelvic position.

[0044] The squeezing force on the pelvis is monitored by the pressure sensor 901, and then electricity is supplied through the four electrodes 905 to perform electrotherapy on the patient's pelvic area. The initial intensity is 5mA, and the patient feels a slight tingling sensation. The intensity is gradually increased by 1mA every 2 minutes to the maximum tolerance value. The treatment lasts for 20 to 30 minutes per time, and is used to treat pelvic floor nerve damage or chronic pain.

[0045] After the treatment, the patient bends his legs and places his feet on the bed 1. The adjustment structure 3 and the lifting structure 8 are then controlled to fit the two squeezing treatment structures 9 to the patient's knees. The patient's legs are pushed to both sides. The pressure sensor 901 monitors the patient's leg thrust in real time to keep the movement speed constant. The PLC control box 7 automatically adjusts the damping according to the patient's thrust to maintain a fixed resistance, monitors and records the patient's muscle strength changes in real time, and improves the efficiency of training.

[0046] The PLC control box 7 also includes an electrotherapy power supply control module, an analog output module to adjust the current intensity, an integrated PWM module to generate medium and low frequency waveforms, a multi-axis motion control module to synchronously control the coordinated action of the hydraulic cylinder 11 and the two second servo motors 809, a data storage and communication module to record treatment data and support remote monitoring, a safety protection module to prevent mechanical overload, overcurrent, and temperature anomalies, a signal conditioning and anti-interference module to ensure the stability of the pressure sensor signal and avoid electromagnetic interference, which are commonly used control technology means in existing control systems and will not be described in detail here.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
