Description
Technical Field
[0001] The present invention belongs to the technical field related to rehabilitation devices, and more specifically, particularly relates to a shoulder joint fixation device with an auxiliary rehabilitation training function. Background Art
[0002] Currently, during the rehabilitation period after arthroscopic surgery of the shoulder joint and after proximal humerus fracture surgery, a chest suspension fixation device and a lateral abduction fixation device are generally used. However, these two fixation devices only have a fixation effect on the shoulder joint after surgery, and have no promotion effect on early rehabilitation training and shoulder joint function recovery. In the vast majority of patients, due to the lack of early and correct rehabilitation training after shoulder joint surgery, severe adhesion occurs after shoulder joint surgery, the range of motion is poor, and the postoperative effect is greatly reduced. Therefore, for the treatment of such causes, a shoulder joint fixation device for rehabilitation treatment has been developed. However, the shoulder joint fixation devices in the prior art have the following defects: In the prior art, when the shoulder joint fixation device faces different periods of shoulder joint rehabilitation of patients, it is necessary to adjust the angular range of motion of the shoulder joint fixation device so that the range of motion of the injured position of the patient is different at different recovery stages. However, the existing shoulder joint fixation devices cannot adjust the range of motion according to the recovery of the patient's shoulder joint, thus affecting the use of the shoulder joint fixation device; In the prior art, after adjusting the range of motion of the shoulder joint fixation device, due to the relatively simple existing limit fixation structure, during the process of the patient's arm swinging up and down, the limit structure is prone to displacement, and the smaller the range of motion of the patient's arm swinging up and down, the faster the impact frequency on the limit structure, so it is necessary to adjust the limit fixation effect of the limit structure according to the change of the range of motion; In the prior art, during the process of assisting the patient to carry out rehabilitation training, it is necessary to cooperate with active assistance and passive assistance for auxiliary training. However, the existing shoulder joint fixation devices cannot perform active or passive rehabilitation training according to the needs of the patient, thus affecting the use of the shoulder joint fixation device.
[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a shoulder joint fixation device with an auxiliary rehabilitation training function is provided, in order to achieve a more practical and valuable purpose.

[0015] Compared with the prior art, the present invention has the following beneficial effects: A shoulder joint fixation device with an auxiliary rehabilitation training function according to the present invention, through the settings of a fixed frame, a U-shaped rod, a sliding plate, and a first elastic rod, when the patient's arm rotates upward or downward, at the same time, the middle part of the U-shaped rod drives the sliding plate to slide up and down in the fixed frame to compress or stretch the first elastic rod to generate elastic force, so that resistance is exerted on the patient's arm during the upward or downward rotation, facilitating active rehabilitation training of the patient's shoulder joint. Further, through the settings of a stepper motor, a circular plate, a second elastic rod, a moving frame, a first slider, and a second slider, when the stepper motor starts to drive the circular plate to rotate, one end of the first slider horizontally slides inside the moving frame and rotates with the first slider, so that the moving frame moves up and down. The up and down movement of the moving frame drives the second elastic rod to move up and down through the second slider, the up and down movement of the second elastic rod drives the sliding plate to move up and down, and the up and down movement of the sliding plate cooperates with the rotation of the U-shaped rod to drive the movable frame to swing back and forth. During the process of the movable frame swinging back and forth to drive the patient to perform shoulder joint abduction activities, the patient's arm rotates upward or downward, thereby performing passive rehabilitation training on the patient's shoulder joint, facilitating the use of active and passive rehabilitation training according to the patient's needs, promoting the recovery of shoulder joint conditions, and improving the use effect of the shoulder joint fixation device.
[0016] A shoulder joint fixation device with an auxiliary rehabilitation training function according to the present invention, through the settings of an operation block, a first movable plate, a hollow elastic member, and a second movable plate, medical staff operate the first movable plate to slide vertically in the fixed frame through the operation block, and the movement of the first movable plate drives the second movable plate to move through two hollow elastic members, and the distance of the upward movement of the sliding plate is adjusted by changing the position of the first movable plate, facilitating the adjustment of the activity range according to the recovery condition of the patient's shoulder joint. Further, through the settings of a first elastic limit block, a moving plate, a limit block, and a spring, when the first movable plate moves downward, it drives two third movable plates and the first elastic limit block to move downward. When the lower side of one end of the first elastic limit block contacts the upper inclined surface of the limit block, the first elastic limit block moves downward to guide and squeeze the limit block, causing the two moving plates to move away from each other; then, under the action of the elastic force of two pairs of springs, the two moving plates move closer to each other, which is beneficial to the stable downward movement of the moving frame and the second movable plate. And when the upper side of one end of the first elastic limit block contacts the upper plane of the limit block, it plays a role in limiting the upward movement of the first movable plate, facilitating the accurate adjustment of the activity range of the U-shaped rod and the sliding plate, and avoiding the situation of changing the activity range of the U-shaped rod and the sliding plate, so as to promote the recovery of shoulder joint conditions.
[0017] A shoulder joint fixing device with an auxiliary rehabilitation training function according to the present invention, through the settings of a connection port, a push rod, a third movable plate, a first elastic limiting block, and a second elastic limiting block, when the sliding plate moves upward, it pushes the second movable plate to move upward. The upward movement of the second movable plate squeezes two hollow elastic members, and the elastic force generated by the squeezing of the two hollow elastic members acts on the second movable plate, thereby buffering the upward movement of the sliding plate. Then, the two hollow elastic members are squeezed, so that the solution inside the hollow elastic members enters the inside of the first movable plate through the connection port. The solution inside the first movable plate pushes the two push rods away from each other. The two push rods moving away from each other drive the two third movable plates to move away from each other. The two third movable plates moving away from each other drive the two first elastic limiting blocks and the second elastic limiting blocks to move away from each other, so that the first elastic limiting block and the second elastic limiting block respectively contact the corresponding two limiting blocks, and the upper sides of one ends of the first elastic limiting block and the second elastic limiting block respectively contact the lower side planes of the corresponding two limiting blocks, thereby improving the limiting and fixing effect on the upward movement of the first movable plate. Through the settings of rubber blocks and card slots, the two hollow elastic members are squeezed and deformed, so that the two rubber blocks move away from each other. The two rubber blocks moving away from each other respectively contact the two limiting blocks. Then, the two limiting blocks enter the two card slots, and the lower side of the card slot contacts the lower side plane of the limiting block, so that the upward movement of the first movable plate can be further limited and fixed, and the situation that the range of movement of the U-shaped rod and the sliding plate changes can be avoided. Finally, through the settings of two guiding plates, the mutually approaching sides of the two guiding plates are in an inclined plane structure, so that the distance between the corresponding two limiting blocks from top to bottom continuously decreases, so that the contact area between the upper side of one end of the first elastic limiting block and the lower side plane of the limiting block continuously increases. So that the smaller the range of movement of the U-shaped rod and the sliding plate, the better the limiting and fixing effect on the upward movement of the first movable plate, which is beneficial to accurately adjusting the range of movement of the U-shaped rod and the sliding plate and avoiding the situation that the range of movement of the U-shaped rod and the sliding plate changes.

The inclined surface on each guide plate 32 is inclined downward from the side away from the first movable plate 27 to the side towards the first movable plate 27 from top to bottom.
[0033] Preferably, referring to the attached Figure 4 to the attached Figure 10 , a second elastic rod 29 is fixed to the lower side of the sliding plate 24.

One end of the second slider 40 slides horizontally inside the moving frame 37.
[0034] Preferably, referring to the attached Figure 1 to the attached Figure 2 , a skin-friendly layer 11 is provided inside the fixed frame 10. A plurality of shock pads 19 are provided inside the movable frame 13. A plurality of through holes 20 are provided on the movable frame 13.
[0035] Preferably, referring to the attached Figure 1 to the attached Figure 2 , on the inner side of one end of each second strap 14, a first magic tape 15 is provided. A plurality of second magic tapes 16 are provided on one side of the movable frame 13. Each first magic tape 15 is attached to the second magic tape 16.
[0036] The specific usage method of the present invention: During the rehabilitation period after arthroscopic shoulder surgery and proximal humerus fracture surgery, a shoulder joint fixation device is needed to assist the patient in rehabilitation training. Medical staff press the fixing frame 10 against the outer side of the patient's waist and use the restraint belt 12 to wrap around the patient's waist, thereby tightening and fixing the fixing frame 10 on the patient's body. Then, the patient's upper arm is inserted into the inside of the movable frame 13. Next, the medical staff fit the first magic tape 15 on the second binding tape 14 with the second magic tape 16, so as to restrain the patient's upper arm through the cooperation of the second binding tape 14 and the movable frame 13. Among them, a number of shock pads 19 are distributed at intervals, so that there are gaps between the shock pads 19, which is conducive to ventilating the skin of the patient's upper arm. Further, a number of through holes 20 are provided on the movable frame 13 to improve the air permeability of the skin of the patient's upper arm.
[0037] When the patient undergoes passive rehabilitation training, the stepper motor 38 starts to drive the circular plate 36 to rotate. One end of the first slider 39 slides horizontally inside the moving frame 37 and rotates with the first slider 39, so that the moving frame 37 moves up and down. The up and down movement of the moving frame 37 drives the second elastic rod 29 to move up and down through the second slider 40. The up and down movement of the second elastic rod 29 drives the slide plate 24 to move up and down. The up and down movement of the slide plate 24 cooperates with the rotation of the U-shaped rod 22 to drive the movable frame 13 to swing back and forth. The back and forth swing of the movable frame 13 drives the patient to perform shoulder abduction activities, causing the patient's arm to rotate up and down repeatedly, so as to perform passive rehabilitation training on the patient's shoulder joint.
[0038] When the patient undergoes active rehabilitation training, during the shoulder abduction activity of the patient, the patient's arm rotates up or down. At the same time, the middle part of the U-shaped rod 22 drives the slide plate 24 to slide up and down inside the fixed frame 21. The upward sliding of the slide plate 24 compresses the first elastic rod 25. The elastic force generated by the compression of the first elastic rod 25 acts on the slide plate 24, so that the upward rotation of the patient's arm is resisted. And the downward sliding of the slide plate 24 stretches the first elastic rod 25, and the stretching of the first elastic rod 25 generates elastic force, so that the downward rotation of the patient's arm is resisted, in order to facilitate the active rehabilitation training of the patient's shoulder joint.
[0039] Next, the medical staff operates the first movable plate 27 to slide vertically within the fixed frame 21 through the operation block 26. The movement of the first movable plate 27 drives the second movable plate 28 to move through the two hollow elastic members 30. By changing the position of the first movable plate 27, the distance of the upward movement of the sliding plate 24 is adjusted, so as to adjust the range of motion according to the recovery of the patient's shoulder joint, which is beneficial to improving the use effect of the shoulder joint fixing device. Among them, when the first movable plate 27 moves downward, it drives the two third movable plates 42 and the first elastic limit block 43 to move downward. One end of the first elastic limit block 43 contacts the upper inclined surface of the limit block 33, so that the downward movement of the first elastic limit block 43 guides and squeezes the limit block 33, causing the two moving plates 31 to move away from each other. The two moving plates 31 moving away from each other respectively compress the two pairs of springs 35 to generate elastic forces. The elastic forces generated by the two pairs of springs 35 act on the two moving plates 31 respectively. When the first elastic limit block 43 is separated from the limit block 33, under the action of the elastic forces of the two pairs of springs 35, the two moving plates 31 move closer to each other, which is beneficial to the stable downward movement of the moving frame 37 and the second movable plate 28. And the upper side plane of the limit block 33 contacts the upper side of one end of the first elastic limit block 43, so as to limit the upward movement of the first movable plate 27, so as to accurately adjust the range of motion of the U-shaped rod 22 and the sliding plate 24, and avoid the situation where the range of motion of the U-shaped rod 22 and the sliding plate 24 changes.
[0040] Finally, when the sliding plate 24 moves upward and contacts the second movable plate 28, the upward movement of the sliding plate 24 pushes the second movable plate 28 upward. The upward movement of the second movable plate 28 squeezes the two hollow elastic members 30. The elastic force generated by the squeezing of the two hollow elastic members 30 acts on the second movable plate 28, thereby buffering the upward movement of the sliding plate 24. Then, the two hollow elastic members 30 are squeezed, so that the solution inside the hollow elastic members 30 enters the inside of the first movable plate 27 through the connection port 34. The solution inside the first movable plate 27 pushes the two push rods 41 away from each other. The two push rods 41 moving away from each other drive the two third movable plates 42 away from each other. The two third movable plates 42 moving away from each other drive the two first elastic limit blocks 43 and the second elastic limit block 44 away from each other, so that the first elastic limit block 43 and the second elastic limit block 44 respectively contact the corresponding two limit blocks 33 and the upper sides of one ends of the first elastic limit block 43 and the second elastic limit block 44 respectively contact the lower side planes of the corresponding two limit blocks 33, thereby enhancing the limiting and fixing effect on the upward movement of the first movable plate 27. At the same time, the two hollow elastic members 30 are squeezed and deformed, so that the two rubber blocks 45 move away from each other. The two rubber blocks 45 moving away from each other respectively contact the two limit blocks 33. Then, through the two limit blocks 33 entering the two card slots 46 and the upper sides of the card slots 46 contacting the upper side planes of the limit blocks 33, the limiting and fixing effect on the upward movement of the first movable plate 27 can be further enhanced, avoiding the situation where the movement ranges of the U-shaped rod 22 and the sliding plate 24 change.
[0041] A shoulder joint fixation device with an auxiliary rehabilitation training function according to the present invention, through the settings of the fixing frame 21, U-shaped rod 22, sliding plate 24, and first elastic rod 25, when the patient's arm rotates upward or downward, at the same time, the middle part of the U-shaped rod 22 drives the sliding plate 24 to slide up and down in the fixing frame 21 to compress or stretch the first elastic rod 25 to generate elastic force, so that the patient's arm is subjected to resistance during the upward or downward rotation process, facilitating the active rehabilitation training of the patient's shoulder joint. Then, through the settings of the stepper motor 38, circular plate 36, second elastic rod 29, moving frame 37, first slider 39, and second slider 40, when the stepper motor 38 is started to drive the circular plate 36 to rotate, one end of the first slider 39 horizontally slides inside the moving frame 37 and rotates with the first slider 39, so that the moving frame 37 moves up and down. The up and down movement of the moving frame 37 drives the second elastic rod 29 to move up and down through the second slider 40, the up and down movement of the second elastic rod 29 drives the sliding plate 24 to move up and down, and the up and down movement of the sliding plate 24 cooperates with the rotation of the U-shaped rod 22 to drive the movable frame 13 to swing back and forth. During the process that the movable frame 13 swings back and forth to drive the patient to perform shoulder joint abduction activities, the patient's arm rotates upward or downward, so as to perform passive rehabilitation training on the patient's shoulder joint, facilitating the use of active and passive rehabilitation training according to the patient's needs, promoting the recovery of shoulder joint conditions, and improving the use effect of the shoulder joint fixation device.
[0042] A shoulder joint fixation device with an auxiliary rehabilitation training function according to the present invention, through the settings of the operation block 26, first movable plate 27, hollow elastic member 30, and second movable plate 28, medical staff operate the first movable plate 27 to slide vertically in the fixing frame 21 through the operation block 26. The movement of the first movable plate 27 drives the second movable plate 28 to move through two hollow elastic members 30. By changing the position of the first movable plate 27, the distance of the upward movement of the sliding plate 24 is adjusted, facilitating the adjustment of the activity range according to the recovery of the patient's shoulder joint. Then, through the settings of the first elastic limit block 43, moving plate 31, limit block 33, and spring 35, when the first movable plate 27 moves downward, it drives two third movable plates 42 and the first elastic limit block 43 to move downward. One end of the first elastic limit block 43 contacts the upper inclined surface of the limit block 33, so that the first elastic limit block 43 moves downward to guide and squeeze the limit block 33, causing the two moving plates 31 to move away from each other; then, under the action of the elastic force of two pairs of springs 35, the two moving plates 31 move closer to each other, which is beneficial to the stable downward movement of the moving frame 37 and the second movable plate 28. And through the upper side plane of the upper end of the first elastic limit block 43 contacting the upper side plane of the limit block 33, the upward movement of the first movable plate 27 is limited, facilitating the accurate adjustment of the activity range of the U-shaped rod 22 and the sliding plate 24, and avoiding the situation of changing the activity range of the U-shaped rod 22 and the sliding plate 24, so as to promote the recovery of shoulder joint conditions.
[0043] A shoulder joint fixing device with an auxiliary rehabilitation training function according to the present invention, through the settings of the connection port 34, the push rod 41, the third movable plate 42, the first elastic limiting block 43, and the second elastic limiting block 44, when the sliding plate 24 moves upward, it pushes the second movable plate 28 to move upward. The upward movement of the second movable plate 28 squeezes the two hollow elastic members 30. The squeezing of the two hollow elastic members 30 generates elastic force acting on the second movable plate 28, thereby buffering the upward movement of the sliding plate 24. Then, the two hollow elastic members 30 are squeezed, so that the solution inside the hollow elastic members 30 enters the inside of the first movable plate 27 through the connection port 34. The solution inside the first movable plate 27 pushes the two push rods 41 away from each other. The two push rods 41 moving away from each other drive the two third movable plates 42 to move away from each other. The two third movable plates 42 moving away from each other drive the two first elastic limiting blocks 43 and the second elastic limiting blocks 44 to move away from each other, so that the first elastic limiting block 43 and the second elastic limiting block 44 respectively contact the corresponding two limiting blocks 33, and the upper sides of one ends of the first elastic limiting block 43 and the second elastic limiting block 44 respectively contact the lower side planes of the corresponding two limiting blocks 33, thereby improving the limiting and fixing effect on the upward movement of the first movable plate 27. Furthermore, through the settings of the rubber blocks 45 and the card slots 46, the two hollow elastic members 30 are squeezed and deformed, so that the two rubber blocks 45 move away from each other. The two rubber blocks 45 moving away from each other respectively contact the two limiting blocks 33. Then, the two limiting blocks 33 enter the two card slots 46, and the lower sides of the card slots 46 contact the lower side planes of the limiting blocks 33, thereby being able to further limit and fix the upward movement of the first movable plate 27 and avoid the situation where the movement ranges of the U-shaped rod 22 and the sliding plate 24 change. Finally, through the settings of the two guiding plates 32, the mutually approaching sides of the two guiding plates 32 are in an inclined surface structure, so that the distance between the corresponding two limiting blocks 33 from top to bottom continuously decreases, so that the contact area between the upper side of one end of the first elastic limiting block 43 and the lower side plane of the limiting block 33 continuously increases. So that the smaller the movement ranges of the U-shaped rod 22 and the sliding plate 24 are, the better the limiting and fixing effect on the upward movement of the first movable plate 27 is, which is beneficial to accurately adjusting the movement ranges of the U-shaped rod 22 and the sliding plate 24 and avoiding the situation where the movement ranges of the U-shaped rod 22 and the sliding plate 24 change.
