Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an orthopedic joint postoperative training device. Background Art

[0002] Existing Chinese patent (CN112957672B) knee joint postoperative rehabilitation training device:

[0003] By providing a first and a second give-way slot in the first movable rod and the second movable rod, and cooperating with the first and the second slider in the first and the second give-way slot, the torsion spring can be fixed between the first and the second slider, and the adjusting rod on the torsion spring is fixed by the electric winding device through a pull rope. When the electric winding device is wound or unwound, the deformation trend of the adjusting rod or the torsion spring itself is driven by the pull rope to change the distance between the torsion spring and the connection point between the first movable rod and the second movable rod. The different distances between the torsion spring and the connection point between the first movable rod and the second movable rod mean that the deformation amount of the torsion spring is different, so that when the patient uses the knee joint postoperative rehabilitation trainer for training, the assistance provided by the torsion spring is also different, which can correspond to the different needs of the patients. However, this method has the following defects:

[0004] After knee surgery, not only muscle strength training is needed, but also flexion training is needed. The above method cannot effectively train the flexion of the knee joint, has a relatively single function, and has great limitations. Moreover, when performing muscle strength training, the patient needs to hold the pull rod with his hands and push the pedal tube with his legs. At this time, the patient's hands will not get a rest, which undoubtedly increases the difficulty of training for the patient and accelerates the patient's physical exhaustion, which in turn easily affects the patient's knee joint training and greatly reduces the training effect. In addition, when performing knee joint flexion training in the existing technology, the curvature of the knee is relatively fixed and single. When the patient uses different curvatures for training during the training cycle, the brace must be removed first, and then put on after adjusting the required angle, which brings great inconvenience to the patient's training and is not conducive to the patient's rehabilitation training.

[0045] The inner wall of the first extrusion block 312 is provided with a plurality of protrusions at equal intervals in an annular manner to increase the friction between the first extrusion block 312 and the calf.

[0046] The ends of the plurality of second extrusion blocks 413 away from the third fixing plate 412 are each provided with a hemispherical head for cooperating with the plurality of push rods 414 .

[0047] Both ends of the multiple push rods 414 are provided with hemispherical heads, and a spring is sleeved on the outside of each push rod 414. One end of the spring is fixed to the push rod 414, and the other end is fixed to the push plate 409 for pressing the patient's foot.

[0048] The right portions of the two support frames 402 are equidistantly penetrated with a plurality of circular holes for engaging with the two latches 419 .

[0049] A threaded rod 4161 is connected between the connecting plate 408 and the fourth sliding block 415 on the same side, and two nuts 4162 are screwed onto the right part of the threaded rod 4161 for adjusting the distance between the connecting plate 408 and the fourth sliding block 415, thereby adjusting the deformation of the third elastic member 416.

[0050] The first elastic member 211 , the second elastic member 313 and the third elastic member 416 are all springs.

[0051] When preparing for training: move the orthopedic joint postoperative trainer to the designated position and keep the two legs 1 and the pillar 2 level. Then guide the patient to sit on the cushion 208 with the back resting on the backrest 203 and both feet placed on a leg rest 210. Then, each hand holds an armrest 401 to maintain stability.

[0052] During the flexion training: the accompanying person puts the patient's leg into the brace 304, and wears the brace 304 accurately at the patient's knee joint position, and then locks the brace 304. Since the patient's muscles are severely atrophied and the legs are weak after the operation, it is difficult for the patient to complete the flexion training independently. At this time, the control motor 302 is started, the output shaft of the motor 302 rotates to drive the transmission shaft 303 to rotate, the transmission shaft 303 rotates to drive the connecting rod 308 to rotate, the connecting rod 308 rotates to drive the second sliding block 309 to rotate, the second sliding block 309 rotates to drive the fixing rod 310 to rotate, the fixing rod 310 rotates to drive the second fixing plate 311 to rotate, and the second fixing plate 311 rotates. The rotation of 311 drives the first extrusion block 312 to rotate until the first extrusion block 312 is rotated to fit the patient's calf. Then the motor 302 continues to operate, and the output shaft of the motor 302 rotates to drive the transmission shaft 303 to continue to rotate, thereby driving all related components to continue to rotate, thereby driving the first extrusion block 312 to rotate. At this time, the rotation of the first extrusion block 312 squeezes the patient's calf and causes the patient's calf to bend. At the same time, the bending of the patient's calf drives the corresponding leg support 210 to rotate, and causes the sliding frame 209 to slide to the left, thereby compressing the corresponding two first elastic members 211. At the same time, in order to avoid the bending angle being uncontrollable during bending, and the bending The uneven and uneven force during bending increases the patient's pain. After the first squeezing block 312 rotates to fit the patient's calf, the first squeezing block 312 continues to rotate. At this time, the bending angle can be obtained by referring to the scale 307. Then, multiple reciprocating training is performed according to the training amount. That is, the motor 302 is controlled to start, and the output shaft of the motor 302 rotates to drive the transmission shaft 303 to rotate in the opposite direction, thereby driving all related components to rotate, and then driving the first squeezing block 312 to rotate, so that the patient's calf is close to horizontal. At the same time, the second elastic member 313 is used to prevent the patient from receiving uneven force during bending training, and to provide a support when the calf is reset and close to the horizontal state. The upward thrust reduces the pain felt by the patient during flexion training, visualizes the flexion, and improves the training effect. When the flexion required for different training stages is different, the motor 302 is controlled to operate, and the output shaft of the motor 302 rotates to drive the transmission shaft 303 to continue rotating, thereby driving all related components to rotate, thereby achieving the flexion required for training. At the same time, the second elastic member 313 is further compressed, thereby increasing the deformation of the second elastic member 313, that is, providing a greater thrust when the calf is reset to a horizontal state, thereby adapting to different training stages and completing periodic knee flexion training.

[0053] Before performing muscle strength training: at this time, the patient's calf is placed flat on the leg support 210, and the soles of the feet are close to the multiple push rods 414 and the multiple elastic plates 420. In order to promote blood circulation in the legs, the two electric sliders 411 are controlled to move toward each other along the electric slide rail 410. The movement of the two electric sliders 411 drives the two third fixing plates 412 to move. The movement of the two third fixing plates 412 drives the corresponding multiple second squeezing blocks 413 to move. At this time, the multiple second squeezing blocks 413 move until they touch the corresponding multiple push rods 414 and squeeze the multiple push rods 414, thereby causing the push rods 414 to move to the left. At this time, the multiple push rods 414 moving to the left will touch the soles of the patient's feet and squeeze the patient's feet, thereby massaging the patient's feet to promote blood circulation in the patient's legs;

[0054] During muscle strength training: the patient adjusts his sitting posture, bends his legs slightly on the two leg supports 210, and makes the soles of his feet press against the two push plates 409. Then, the patient's legs gradually straighten, and then push the push plate 409 to move to the right. At this time, the push plate 409 moves and drives the two connecting plates 408 to move. The two connecting plates 408 move and compress the two third elastic members 416. Then, the two third elastic members 416 generate a rebound force to reset the two third elastic members 416, thereby completing a muscle strength training. At the same time, the two connecting plates 408 move and drive the two third sliding blocks 407 to move. The movement of the block 407 drives the two racks 404 to move, and the movement of the two racks 404 drives the two spur gears 405 to rotate, and the rotation of the two spur gears 405 drives the connecting shaft 202 to rotate, and the rotation of the connecting shaft 202 drives the backrest 203 to rotate, thereby compressing the telescopic rod 205 and causing the first sliding block 204 to move backward, thereby causing the patient's upper body to be stretched backward, thereby making the body more coordinated and increasing the interaction between various parts of the body, thereby improving the fun of the exercise. Then, according to the training amount, the training is repeated multiple times according to the above working principle to complete the periodic training;

[0055] When it is necessary to adjust the training intensity according to different training cycles: the accompanying personnel removes the pin 419, and then tightens the nut 4162 with a wrench, so that the fourth sliding block 415 moves along the support frame 402 and approaches the connecting plate 408, and then inserts the pin 419 into the circular hole equidistantly passing through the right part of the support frame 402, thereby compressing the deformation of the third elastic member 416, that is, when the patient's legs gradually straighten and push the push plate 409 to move to the right, the required force will increase, and then the corresponding training intensity will be adjusted according to the different training cycles of the patient, thereby achieving different training intensities adjusted according to different training cycles.

[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
