DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] Refer to the instruction manual Figure 1-Figure 11 The present invention provides a shoulder joint rehabilitation training stretching device after rotator cuff injury repair surgery, comprising a base 1, a detachable fixing seat 3 is provided at the top of the base 1, a rotatable training disk 6 is provided on one side of the fixing seat 3, and the shoulder joint is moved by rotating the training disk 6, thereby achieving the purpose of training;

[0040] An arm positioning assembly 7 for fixing the arm is provided on a side of the training plate 6 away from the fixing seat 3. The arm positioning assembly 7 includes a rotating plate 702. A soft pad 703 is fixedly provided on a side of the rotating plate 702 away from the training plate 6. The patient's elbow contacts the soft pad 703. The soft pad 703 is soft in texture, which improves the comfort of training. A guard plate 704 is fixedly provided on the outer end of the rotating plate 702.

[0041] A pressure arm 705 is hinged at the outer end of the turntable 702, and an arc-shaped pressure plate 706 is fixedly provided at one end of the pressure arm 705. The guard plate 704 and the arc-shaped pressure plate 706 are respectively located on both sides of the turntable 702, and the arm can be clamped between the guard plate 704 and the arc-shaped pressure plate 706. The arc-shaped guard plate 704 and the arc-shaped pressure plate 706 better fit the contour of the arm.

[0042] Before training, the patient folds his arm, folds his forearm and presses it against his upper arm, then clamps the folded arm between the guard plate 704 and the arc pressure plate 706 and fixes it, with the elbow against the cushion 703. Then, the patient drives the upper arm to rotate through the rotation of the shoulder joint, and the elbow pushes the arm positioning component 7 and drives the training disk 6 to rotate, thereby rotating and stretching the muscles of the patient's shoulder joint, achieving the purpose of rehabilitation training. When training in this way, the patient's forearm is folded on the upper arm and clamped, so that the patient's forearm, elbow joint and wrist joint cannot move and participate in the training process, so that the patient only has shoulder joint movement during training, reducing the interference of other joints on the shoulder joint, and can avoid the resistance of the shoulder joint being offset during strength training, thereby avoiding the reduction of the training intensity of the shoulder joint, thereby improving the training effect.

[0043] In order to fix the arms in the folded state, Figure 7-Figure 9 As shown, two end plates 709 are fixedly provided at the outer end of the rotating disk 702, a fixed shaft 707 is provided between the two end plates 709, and both ends of the fixed shaft 707 are rotatably connected to the two end plates 709, and the pressure arm 705 is fixedly provided at the outer end of the fixed shaft 707, and both ends of the fixed shaft 707 are provided with torsion springs 708, and both ends of the torsion spring 708 are respectively connected to the pressure arm 705 and the end plate 709 on the corresponding side;

[0044] After the patient folds his arm, the pressure arm 705 is driven to rotate by rotating the fixed shaft 707, so that the arc pressure plate 706 moves away from the guard plate 704. The rotation of the fixed shaft 707 further tightens the torsion spring 708. The folded upper arm and lower arm are inserted between the guard plate 704 and the arc pressure plate 706, and the elbow is pressed against the cushion 703. At this time, the pressure arm 705 is released, and the fixed shaft 707 rotates in the opposite direction under the elastic force of the torsion spring 708, and drives the pressure arm 705 and the arc-shaped pressure plate 706 move backwards, and the arc-shaped pressure plate 706 is finally pressed on the patient's arm, and the guard plate 704 and the arc-shaped pressure plate 706 clamp the folded upper arm and forearm therein, and the elastic force of the torsion spring 708 makes the fixed axis 707 have a tendency to rotate further, but under the obstruction of the arm, the arc-shaped pressure plate 706 can no longer move, so the elastic force of the torsion spring 708 is finally applied to the patient's folded arm through the arc-shaped pressure plate 706, clamping the arm and keeping it in a folded state.

[0045] A slide bar 601 is provided on the side of the training disk 6 away from the fixed seat 3, and side plates are fixedly provided at both ends of the slide bar 601. One end of the side plate is fixedly provided on the training disk 6. A slide seat 602 is sleeved on the outer end of the slide bar 601. The cross section of the slide bar 601 is rectangular, which can fix the slide seat 602 to prevent the slide seat 602 from rotating around the slide bar 601. A fastening bolt is provided on the outer end of the slide seat 602 through a thread. A transfer seat 701 is fixedly provided on the side of the slide seat 602 away from the training disk 6. The rotating disk 702 faces one side of the training disk 6. The side is rotatably connected to the adapter 701. During training, the turntable 702 rotates relative to the adapter 701, which allows the elbow to smoothly push the training disk 6 to rotate without rubbing against the soft pad 703 during training. Sliding the slide 602 at the outer end of the slide bar 601 can adjust the position of the arm positioning component 7. The position of the arm positioning component 7 is different, and its distance from the center of the training disk 6 is different, and the rotation radius of the arm positioning component 7 is different. In this way, the rotation radius of the arm positioning component 7 is adjusted according to the patient's arm size.

[0046] In order to provide resistance to shoulder movement, Figure 7 As shown, the fixing seat 3 is rotatably connected with a connecting shaft 901, the connecting shaft 901 penetrates the fixing seat 3, one end of the connecting shaft 901 is fixedly connected with the training disk 6, and the other end of the connecting shaft 901 is fixedly provided with a resistance wheel 9. Under the connection of the connecting shaft 901, the training disk 6 and the resistance wheel 9 can rotate synchronously. After the patient's elbow drives the training disk 6 to rotate, the training disk 6 can drive the resistance wheel 9 to rotate through the connecting shaft 901.

[0047] like Figure 4-Figure 6 and Fig.11As shown, the outer end of the resistance wheel 9 is provided with two resistance applying components 5 distributed inside and outside, the side of the fixed seat 3 facing the training disk 6 is fixedly provided with a controller 4, and the controller 4 is located on the lower side of the training disk 6, and the side of the fixed seat 3 away from the training disk 6 is provided with a boss, and four sockets 301 are opened at the top of the boss, and an iron block 302 is fixed at the inner bottom end of the socket 301, and two springs 10 are provided at the top of the boss.

[0048] The top end of the resistance applying assembly 5 is sleeved with two arc-shaped plates 501, and the inner side of the arc-shaped plates 501 is provided with a detachable rubber sheet 506, which can be removed and replaced according to the wear condition. The rubber sheet 506 contacts the outer end of the resistance wheel 9, and friction is generated between the resistance wheel 9 and the rubber sheet 506 after the rotation, thereby providing resistance to the rotation of the resistance wheel 9, and further providing resistance for shoulder training;

[0049] The resistance applying assembly 5 further includes a horizontal plate 503 located below the resistance wheel 9, and tension arms 502 are provided at both ends of the arc-shaped plate 501, and the bottom end of the tension arm 502 is detachably connected to the top end of the horizontal plate 503, and two insertion rods 504 are fixedly provided at the bottom end of the horizontal plate 503;

[0050] The bottom ends of the four plug rods 504 extend to the inside of the four sockets 301 respectively, and an electromagnet 505 is fixedly provided at the bottom end of the plug rod 504. The electromagnet 505 is arranged at the output end of the controller 4. Two springs 10 are arranged below the horizontal plate 503 of the outer resistance applying component 5, and the top ends of the springs 10 are connected to the horizontal plate 503. When the electromagnet 505 is energized, a magnetic force is generated to attract the iron block 302. The position of the iron block 302 is fixed, so the magnetic force is converted into a downward pulling force on the electromagnet 505 and the plug rod 504, pulling the horizontal plate 503, the pulling arm 502 and the arc plate 501 downward, so that the rubber sheet 506 is in close contact with the outer end of the resistance wheel 9. After the resistance wheel 9 rotates, friction is generated with the rubber sheet 506, and the rotation of the resistance wheel 9 therefore has resistance. The resistance wheel 9 rotates synchronously with the training disk 6 when the connecting shaft 901 is connected, and the rotation of the training disk 6 therefore has resistance.

[0051] The patient's shoulder movement needs to overcome the resistance of the rotation of the training disk 6, so that the strength of the patient's shoulder is trained, which is beneficial to increase the muscle strength of the shoulder and improve the efficiency of the patient's rehabilitation. The magnetic force of the two electromagnets 505 of the inner resistance applying component 5 can be adjusted by adjusting the current in the circuit, thereby adjusting the resistance of the patient's training, and then providing the patient with appropriate training intensity according to the patient's rehabilitation condition.

[0052] When training in a sitting position, the upper limbs and trunk need to be fixed to avoid interference of the waist on the shoulder joint training, such as Figure 4 , Figure 5 , Figure 6 , Fig.10 and Fig.11 As shown, a seat 8 is provided on the side of the arm positioning assembly 7 away from the training plate 6, and the seat 8 includes a seat board 801, a cushion for improving comfort is fixedly provided on the top of the seat board 801, and a backrest 802 is fixedly provided on the top of one side of the seat board 801. During training, the patient sits on the seat board 801 and leans his back on the backrest 802;

[0053] A trunk strap 11 is provided on the backrest 802, and a tension sensor 12 installed on the backrest 802 is provided at one end of the trunk strap 11, and the tension sensor 12 is arranged at the input end of the controller 4. A fixing frame is fixedly provided at the outer end of the backrest 802, and a fixing bolt is provided on the fixing frame through a thread. The trunk strap 11 is passed around the patient's upper limb trunk, and then the movable end of the trunk strap 11 is inserted into the fixing frame, and then the fixing bolt is tightened to fix the movable end. In this way, the patient's upper limb torso is bound by the trunk strap 11, the movement of the patient's upper limb torso is restricted, and the strength of the waist is prevented from interfering with the exercise of the shoulders.

[0054] In a normal binding state, the trunk strap 11 is in a slightly tightened state. At this time, the tension applied by the tightened trunk strap 11 to the tension sensor 12 is 15N. The trunk strap 11 is tied to the patient's chest. If the patient's upper limbs and trunk swing along with the shoulder exercise during training, it means that the waist is moving and interfering with the shoulder exercise. The swing of the upper limbs and trunk will further tighten the trunk strap 11, and the tension sensed by the tension sensor 12 will further increase. Therefore, if the tension sensed by the tension sensor 12 is greater than 20N, the two electromagnets 505 of the outer resistance applying component 5 will be energized through the controller 4, thereby increasing the friction force applied by the outer resistance applying component 5 on the resistance wheel 9;

[0055] And on this basis, for every 1N increase in the force felt by the tension sensor 12, under the action of the electromagnet 505, the downward pulling force received by the outer resistance applying component 5 increases by 1N, thereby increasing the friction force of the outer resistance applying component 5 on the resistance wheel 9, and then increasing the resistance when the training disk 6 rotates, so that the resistance during shoulder training is greater, and the increased resistance is used to offset the assistance of the waist strength to the shoulder training, so that the shoulders are trained more fully, avoiding the interference of the waist strength, and further improving the training effect. The tension sensor 12 can only control the electromagnet 505 of the outer resistance applying component 5, and the electromagnet 505 of the inner resistance applying component 5 is not affected by the tension sensor 12. When the tension sensed by the tension sensor 12 does not exceed 20N, the two outer electromagnets 505 are not energized, and the outer resistance applying component 5 only relies on the elastic force of the spring 10 to provide the downward pulling force.

[0056] Both arms of the patient can be trained, e.g. Figure 2 , Figure 3 , Fig.10 As shown, a column 2 is fixedly provided at the top of the base 1, a movable seat 201 is sleeved on the outer end of the column 2, a support beam 202 is provided on the side of the movable seat 201 facing the seat 8 through bolts, a mounting seat 203 is provided on the outer end of the support beam 202 through bolts, and the seat plate 801 is rotatably connected to the top of the mounting seat 203.

[0057] Rotating the seat plate 801 can make the seat plate 801 rotate around the mounting seat 203. Rotating 180° can adjust the overall direction of the chair 8, thereby changing the patient's body orientation and further adjusting the patient's arm position so that both sides of the patient's shoulders can be trained.

[0058] Positioning plates 803 are fixedly provided on both sides of the seat plate 801, and a through hole is opened on the positioning plate 803. A sleeve 804 is fixedly provided on the top of the support beam 202. The sleeve 804 is located directly below one of the positioning plates 803. The positioning plate 803 is provided with a positioning pin 805 that penetrates the positioning plate 803, and the bottom end of the positioning pin 805 is inserted into the sleeve 804.

[0059] Each time the position is adjusted, the two positioning plates 803 will be moved alternately to the top of the sleeve 804, and the corresponding positioning plates 803 will be connected to the sleeve 804 through the positioning pin 805, so as to fix the position of the seat 8 to prevent it from rotating during training.

[0060] Before training, the patient's sitting posture needs to be adjusted, such as Figure 1 , Fig.10 As shown, a driving seat 204 is fixedly provided at one end of the movable seat 201 away from the fixed seat 3, a threaded rod 205 is threadedly provided on the driving seat 204, the threaded rod 205 penetrates the driving seat 204, a hand wheel is fixedly provided at the top of the threaded rod 205, and the bottom end of the threaded rod 205 is rotatably connected to the base 1.

[0061] The threaded rod 205 can be driven by turning the hand wheel. Under the action of the thread, the threaded rod 205 can rotate to make the driving seat 204 move up and down along the threaded rod 205. The driving seat 204 thus drives the movable seat 201 to move up and down along the column 2. The support beam 202 and the mounting seat 203 are thus driven by the movable seat 201. The mounting seat 203 thus drives the seat 8 to rise and fall, thereby adjusting the height of the seat 8, and in turn adjusting the height of the sitting posture according to the patient's body shape, with a wider range of applications.

[0062] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
