DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0029] See also Figure 1 - Figure 5 In this embodiment, a multi-dimensional load device for musculoskeletal ultrasonic evaluation is provided, which is specifically used for clinical imaging diagnosis of the musculoskeletal system, and specifically comprises: a frame 1, a hip support module 2 is fixed on the base of the frame 1, a foot resistance module 3 is symmetrically arranged, two groups of shoulder load modules 4 are symmetrically arranged on the top 11 of the frame 1, and hand pulling modules 5 are also arranged on both sides of the top 11 of the frame 1 away from the center position;

[0030] The hip support module 2 includes a seat cushion 21 for supporting the hips, an air bag 22 is provided at the bottom 12 of the seat cushion 21, a seat rod 23 is connected below the air bag 22, and the seat rod 23 is slidably provided on the base of the frame 1;

[0031] The foot resistance module 3 comprises a base plate 32 and a pedal 31, one end of the base plate 32 is hinged to one end of the pedal 31, and the other end of the base plate is connected and adapted to the other end of the pedal 31 through a rebound structure 33;

[0032] The shoulder load module 4 includes a downward pressure pad 42, and the downward pressure pad 42 is connected to a cylinder 41, and a cylinder body 411 of the cylinder 41 is fixed to the top 11 of the frame 1;

[0033] The hand-pulling module 5 comprises a gripping portion 51 , and the gripping portion 51 is connected to a pulley block 52 and a gravity box 53 , in which a weight 54 is placed.

[0034] Specifically, in this embodiment, ultrasound technology can observe the movement state of musculoskeletal tissue in real time, and is particularly suitable for the musculoskeletal system related to exercise. By observing the morphological changes of the patient's joints, bones, muscles and tendons during exercise, it can help diagnose movement diseases and impingement syndrome, which is beneficial to the patient's subsequent rehabilitation work.

[0035] Musculoskeletal ultrasound evaluation in a sitting position: Before the specific operation, the frame 1 needs to be disinfected in all directions. The patient's buttocks are placed on the seat cushion 21, and the patient's feet are placed on the pedal 31. The airbag 22 is connected to the air pump, and the airbag 22 is inflated and deflated by the air pump, so that the airbag 22 expands and contracts. This embodiment uses a telescopic airbag 22. When the airbag 22 expands, the height of the seat cushion 21 is raised, and when the airbag 22 contracts, the height of the seat cushion 21 is reduced. In the process of raising and lowering the seat cushion 21 (the patient's buttocks remain stationary on the seat cushion 21, and the feet are always in contact with the pedal 31), the seat cushion 21 is raised, the knee joint is straightened, and the triceps surae are relaxed. The seat cushion 21 is lowered, the knee joint is flexed, and the triceps surae are stressed, which is convenient for ultrasonic evaluation of the knee joint and the musculoskeletal activity state of the calf.

[0036] When performing musculoskeletal ultrasonic evaluation of the ankle joint, the height of the seat cushion 21 must first be fixed by the airbag 22 (adjust to a suitable sitting position according to the patient's body shape, so that the contact area between the patient and the seat cushion 21 occupies about 2 / 3 of the buttocks, and the calf is in contact with the pedal 31). The patient uses the foot resistance module 3 to achieve two forms of movement for the ankle joint, flexion and extension. By setting a rebound structure 33 to work together with the pedal 31, the pedal 31 can automatically rebound during the process of the patient's ankle joint changing from flexion to extension. The patient can repeat the flexion and extension of the ankle joint for many times, which is convenient for ultrasonic evaluation of the musculoskeletal activity state at the ankle joint.

[0037] Overall assessment of standing status: The above-mentioned load acts in the form of ultrasonic evaluation of the movement state of the patient's lower limb musculoskeletal muscles. The patient needs to change from a sitting state to a standing state. In this embodiment, the patient stands on a base with his feet shoulder-width apart. The cylinder 41 drives the downward pressure pad 42, which contacts the patient's shoulder. The cylinder 41 slowly advances with a small displacement. The patient is subjected to downward pressure from the shoulder and supported on the base with his legs. By arranging a pressure sensing component on the base, pressure data is collected and musculoskeletal ultrasonic evaluation is performed on the patient's legs, shoulders, back and other parts that are moved after being pressed. This helps to understand the response and adaptability of the musculoskeletal system.

[0038] The hand pulling module 5 is mainly used to perform ultrasonic evaluation on the musculoskeletal activity state of the patient's upper limbs. When in use, the patient needs to maintain a standing posture, grasp the gripping part 51 with his hands, and keep his arms raised. The gripping part 51 is connected to the gravity box 53 through a pulley set 52. The patient's upper limbs are subjected to pulling force. By adjusting the total mass of the gravity box 53 (adding weights 54 of different specifications and quantities), the patient can maintain the state of grasping the gripping part 51 with his hands for a long time, and swing his arms up and down, so as to realize musculoskeletal ultrasonic analysis of the patient's upper limbs under the action of different loads.

[0039] The utility model provides an effective auxiliary means for rehabilitation treatment. By monitoring the state of the musculoskeletal system in real time through ultrasound, doctors can better guide patients' rehabilitation training and treatment selection, and provide an effective reference for rehabilitation treatment.

[0040] The rebound structure 33 includes a pressure plate 331 and a spring plate 332. One end of the spring plate 332 is hinged to the base plate 32 via a torsion spring 333, and the other end of the spring plate 332 is hinged to the pressure plate 331. The other end of the pressure plate 331 is hinged to the pedal 31. When the patient's ankle joint performs flexion movement, the pedal 31 will be subjected to the rebound force from the pedal 31. By adopting torsion springs 333 with different elastic forces, the pedal 31 will form different rebound forces, thereby simulating the reaction of the musculoskeletal system at the ankle joint under different load conditions.

[0041] The seat cushion 21 is connected to the backrest 24 via a return spring 25. The seat cushion 21 is provided with a guide hole 211. The backrest 24 is provided with a guide column 241. The guide column 241 is sleeved with the return spring 25. One end of the return spring 25 is fixed to the backrest 24, and the other end is fixed to the guide hole 211 of the seat cushion 21. The patient's buttocks are placed on the seat cushion 21, the feet are supported on the pedal 31, the waist is leaned back, the upper body of the patient leans back, the lumbar spine is stretched, and the patient overcomes the return load of the return spring 25 to push the backrest 24 backward, and the movement state of the muscles and bones in the lumbar spine can be evaluated and analyzed by ultrasound.

[0042] The base is also symmetrically provided with two groups of support rods 13, and each group of support rods 13 is provided with an armrest 14. The armrest 14 can help the patient switch between standing and sitting positions. When the patient needs to stand up, they can use these armrests 14 to maintain balance and stability. The support rod 13 is an electric telescopic rod, and an elbow support pad 15 is provided at the upper end of the support rod 13. The support rod 13 is an electric telescopic rod, which means that it can be adjusted according to the needs of the patient. Through the electric telescopic rod, the doctor or rehabilitation therapist can adjust the height of the base according to the patient's height, weight and other factors, so as to better adapt to different patients for musculoskeletal ultrasound evaluation.

[0043] By combining the elbow support pad 15 and the electric telescopic rod, the hand pulling module 5 is used together. When the patient is standing, his elbow can lean on the elbow support pad 15, and the patient's upper body is in the shape of the letter "W". The extension and retraction of the electric telescopic rod drives the patient's elbow joint to swing up and down, prompting the musculoskeletal movement of the shoulder joint and the upper arm to help doctors perform ultrasonic evaluation and analysis of these parts. In addition, based on the above-mentioned load action, the patient grasps the gripping part 51 with his hand, fixes the position of the electric telescopic rod, so that the height of the patient's elbow joint is fixed, and while grasping the gripping part 51 with his hand, the forearm is swung inward and outward, and the gripping part 51 is pulled by the force of the forearm. At this time, ultrasonic evaluation can be performed based on the musculoskeletal activity state of the elbow joint and wrist joint.

[0044] The base is provided with a screw motor 16, which is threadedly engaged with the connecting portion 231 at the lower end of the seat post 23 through a screw 161. The seat post 23 can be adjusted in front and back positions through the screw motor 16. When the patient needs to stand for musculoskeletal ultrasound, the hip support module 2 moves backward to free up enough movement space for the patient's load operation, providing a better operating environment for musculoskeletal ultrasound evaluation.

[0045] The top 11 of the frame 1 is provided with a dual-axis motor 17, and the motor shafts in front and behind the dual-axis motor 17 are respectively connected with a set of screws 171, and the thread directions of the two sets of screws 171 are opposite, and the screws 171 are matched with the end cover 412 of the cylinder 41 through threaded engagement. The spacing between the two sets of shoulder load modules 4 can be adjusted by the rotation of the dual-axis motor 17, and the shoulder load module 4 connected to the screw 171 can be moved inward or outward by controlling the rotation of the dual-axis motor 17. In this way, the doctor can adjust the distance between the two sets of shoulder load modules 4 in real time according to the needs of the patient and the musculoskeletal ultrasound evaluation, so as to adapt to different patient body shapes and rehabilitation needs, so as to obtain better evaluation results.

[0046] The pulley block 52 includes a fixed pulley 522 fixed to the top 11 of the frame 1, a movable pulley 523 and a pull wire 521, one end of the pull wire 521 is connected to the gripping portion 51, and the pull wire 521 passes through the fixed pulley 522 and the movable pulley 523 in sequence, and the other end of the pull wire 521 is connected to the gravity box 53.

[0047] A guide frame 18 is further provided on the top 11 of the frame 1 on one side of the fixed pulley 522, and the guide frame 18 is provided with a through hole 181. The pull wire 521 passes through the through hole 181 and is connected to the gripping portion 51 below the guide frame 18. The pull wire 521 above the connection is provided with a clamping block 524, and the clamping block 524 cannot pass through the through hole 181. The initial position of the gripping portion 51 (when it is only affected by the gravity box 53 and not grasped by the patient) is determined by the position of the clamping block 524. The height of the gripping portion 51 is adjusted by adjusting the position of the clamping block 524. The patient can easily grasp the gripping portion 51 and perform pulling movements, which is more convenient for doctors to perform musculoskeletal ultrasound evaluation.

[0048] The gripping part 51 is provided with a gripping rod 511, both ends of which are respectively connected to the pull wire 521 of the pulley block 52, and both ends of the gripping rod 511 are hinged with gripping rings 512. The gripping rod 511 is used for the patient to grasp, and the gripping ring 512 is required to be hooked by the patient's fingers, and the musculoskeletal ultrasound evaluation of the finger joints can be performed by extending and flexing the fingers.
