AI Technical Summary
When using the existing knee and hip arthritis orthosis, because the orthosis itself has a certain weight, the patient will bear the impact from the weight of the orthosis when walking after wearing it, which aggravates the wear of the articular cartilage, leads to increased pain, reduces the patient's daily movement ability and comfort, and may even cause muscle atrophy and joint deformities, seriously affecting the patient's quality of life and recovery process.
An adjustable smart orthosis is designed with a buffer mechanism to reduce impact during walking. The buffering mechanism includes a piston rod, a piston, a buffer block, a cylinder, a buffer groove and a buffer spring. When the patient walks, the piston rod drives the piston to squeeze the inner wall of the cylinder downward, increasing the air pressure and generating a reverse pushing force. The buffer spring is squeezed when the buffer block reaches the buffer groove, providing a reverse pushing force, thereby achieving an efficient buffering effect.
Through the setting of the buffer mechanism, the impact force during walking is reduced, the wear of joint cartilage is reduced, the pain is reduced, the patient's daily movement ability and comfort is improved, the occurrence of muscle atrophy and joint deformities is reduced, the patient's recovery process is accelerated, and the quality of life is improved.

Description
Technical Field
[0001] The present invention relates to the technical field related to knee and hip arthritis, and in particular to an adjustable intelligent orthosis for patients with knee and hip arthritis. Background Art
[0002] Knee and hip arthritis is a common chronic joint disease, which is mainly manifested by inflammation, pain, swelling and dysfunction of the knee and hip joints. This disease is usually divided into two types: primary and secondary. The cause of primary knee and hip arthritis is still unclear, and may be related to factors such as genetics, age, obesity, and metabolic abnormalities; secondary knee and hip arthritis is mostly caused by trauma, infection, joint diseases and other factors. The main pathological change is the degenerative lesions of articular cartilage. The cartilage gradually wears and falls off, resulting in narrowing of the joint space and increased friction between bones, causing pain, swelling and limited movement. In addition, the soft tissues around the joints such as synovium, ligaments and muscles may also have inflammatory reactions, further aggravating the symptoms. Therefore, there is a special need for an adjustable intelligent orthosis for patients with knee and hip arthritis.
[0003] When using existing knee and hip arthritis orthoses, since the orthosis itself has a certain weight, the patient's body will bear the impact of the weight of the orthosis when walking after wearing it. This is extremely disadvantageous for patients with knee and hip arthritis. The patient's joints are already fragile due to inflammation. The additional impact will aggravate the wear of the articular cartilage, causing the pain to become more frequent and severe, which not only reduces the patient's ability and comfort in daily activities, but may also affect the patient's walking posture. Over time, it will cause more serious conditions such as muscle atrophy and joint deformities, further aggravating the condition and seriously affecting the patient's quality of life and rehabilitation process.

[0030] Furthermore, the tensioning mechanism 5 includes a fixing plate 501, a sliding groove 502, a clamping strip 503, an adjusting plate 504 and a through hole 505. The outer surface of the waist guard plate 1 is fixedly connected with the fixing plate 501, the inner surface of the fixing plate 501 is provided with a sliding groove 502, the inner surface of the fixing plate 501 is fixedly connected with the clamping strip 503, the inner surface of the fixing plate 501 is slidably connected with the adjusting plate 504, and the outer surface of the adjusting plate 504 is provided with a through hole 505. 05. When in use, when the waist guard 1 is too tight to wear, pull the waist guard 1 to both sides with both hands. During the pulling process, the waist guard 1 will drive the adjustment plate 504 to move along the slide groove 502. When pulled to the appropriate position, the clamping strip 503 will be engaged into the corresponding through hole 505 on the adjustment plate 504, so as to maintain the adjusted tightness; on the contrary, when the waist guard 1 is too loose, squeeze the waist guard 1 inward with both hands, and the adjustment plate 504 will also drive the clamping strip 503 to engage into the corresponding through hole 505.
[0031] Furthermore, two groups of clamping strips 503 are provided on the inner surface of the fixed plate 501, and multiple groups of through holes 505 are provided on the outer surface of the adjustment plate 504. Through the arrangement of the clamping strips 503 and the through holes 505, during use, after the tightness is adjusted, the clamping strips 503 will be engaged into the corresponding through holes 505 on the adjustment plate 504, thereby maintaining the adjusted tightness.
[0032] Further, the outer surface of the waist guard plate 1 is fixedly connected with a connecting block 601, one side surface of the connecting block 601 is fixedly connected with a switch 602, the inner surface of the connecting block 601 is provided with a lifting slot 603, the inner surface of the connecting block 601 is interactively connected with a lifting plate 604, one side surface of the lifting plate 604 is fixedly connected with a rack 605, the outer surface of the rack 605 is meshed with a gear 606, one side surface of the gear 606 is fixedly connected with a rotating rod 607, one side surface of the rotating rod 607 is fixedly connected with a driving motor 608, and the outer surface of the connecting block 601 is provided with a rotating rod slot 609, through the setting of the connecting block 601, the switch 602, the lifting slot 603, the lifting plate 604, the rack 605, the gear 606, the rotating rod 607, the driving motor 608 and the rotating rod slot 609, when in use, when it is necessary to adjust the length of the side, turn on the switch 602, start the driving motor 608, the driving motor 608 drives the rotating rod 607 to rotate, the rotating rod 607 drives the gear 606 to rotate, and the gear 606 drives the lifting plate 604 to move in the vertical direction, so that the length of the lifting plate 604 can be adjusted. When it is adjusted to a suitable length, turn off the switch 602.
[0033] Furthermore, two groups of connecting blocks 601 are provided on the outer surface of the waist guard plate 1, and the inner wall surface size of the lifting groove 603 is consistent with the outer wall surface size of the lifting plate 604. Through the setting of the connecting block 601 and the lifting groove 603, when in use, the lifting groove 603 limits the movement trajectory of the lifting plate 604, so that the lifting plate 604 can only move in the vertical direction, so that the length of the lifting plate 604 can be adjusted more efficiently.
[0034] Furthermore, the fixing mechanism 21 includes a fixing strip 2101, a spring 2102, a snap block 2103, a snap plate 2104 and a snap slot 2105. The fixing strip 2101 is fixedly connected to one side surface of the fixing belt block 13. The spring 2102 is fixedly connected to the inner side surface of the fixing strip 2101. The snap block 2103 is fixedly connected to one side surface of the spring 2102. The snap plate 2104 is fixedly connected to the outer side surface of the calf support strip 19. The snap plate 2104 is provided with a snap slot 2105 on the outer side surface. 3. The arrangement of the locking plate 2104 and the locking slot 2105. When in use, when the fixing strip 2101 is connected to the fixing belt block 13, the inner wall of the fixing belt block 13 will squeeze the locking block 2103, and the locking block 2103 will squeeze the spring 2102, causing the spring 2102 to shrink, so that the locking block 2103 can be retracted into the fixing strip 2101. When the locking block 2103 moves to the position of the locking slot 2105, since there is no obstruction from the inner wall of the fixing belt block 13, the spring 2102 will push the locking block 2103 to move outward, so that the locking block 2103 clamps the fixing belt block 13.
[0035] Furthermore, multiple groups of springs 2102 are arranged on the inner surface of the fixed strip 2101, and the outer wall surface size of the locking block 2103 is consistent with the inner wall surface size of the slot 2105. Through the arrangement of the springs 2102 and the locking block 2103, when in use, when moving to the position of the slot 2105, there is no obstruction from the inner wall of the fixed belt block 13, and the spring 2102 will push the locking block 2103 to move outward in the opposite direction, so that the locking block 2103 can be locked into the slot 2105.
[0036] Furthermore, multiple groups of vents 3 are provided on the outer surface of the lumbar guard 1, and two groups of connecting belts 4 are provided on the outer surface of the lumbar guard 1. Through the provision of the vents 3 and the connecting belts 4, when in use, the vents 3 can increase air circulation and reduce sweat accumulation on the skin surface. When the orthosis is worn for a long time, air can circulate through the vents 3, which helps to relieve the discomfort caused by stuffiness and humidity and improve the comfort of the patient.
[0037] Furthermore, multiple groups of fixing belt blocks 13 are arranged on the outer surface of the thigh support 10, and two groups of fixing belt blocks 13 are arranged on the outer surface of the calf support 19. Through the arrangement of the fixing belt blocks 13, when in use, the fixing belt blocks 13 enable the fixing belt 14 and the fixing strip 2101 to fit firmly with the thigh support 10 and the calf support 19, so that the patient will not easily fall off when wearing it, thereby increasing the convenience of wearing.
[0038] Working principle: When the waist guard 1 is too tight to wear, pull the waist guard 1 to both sides with both hands. During the pulling process, the waist guard 1 will drive the adjustment plate 504 to move along the slide groove 502. When pulled to the appropriate position, the clamping strip 503 will snap into the corresponding through hole 505 on the adjustment plate 504, so as to maintain the adjusted tightness; conversely, when the waist guard 1 is too loose, squeeze the waist guard 1 inward with both hands, and the adjustment plate 504 will also drive the clamping strip 503 to snap into the corresponding through hole 505. When the length of the side needs to be adjusted, turn on the switch 602 to start the drive motor 608, and the drive motor 608 drives the rotating rod 607 to rotate , the rotating rod 607 drives the gear 606 to rotate, and the gear 606 drives the lifting plate 604 to move in the vertical direction, so that the length of the lifting plate 604 can be adjusted. When it is adjusted to a suitable length, turn off the switch 602, and when the fixing strip 2101 is connected to the fixing belt block 13, the inner wall of the fixing belt block 13 will squeeze the locking block 2103, and the locking block 2103 will squeeze the spring 2102, so that the spring 2102 shrinks, and the locking block 2103 can be retracted into the fixing strip 2101. When the locking block 2103 moves to the position of the slot 2105, the spring 2102 will push the locking block 2103 to move outward because there is no obstruction from the inner wall of the fixing belt block 13. When the patient walks, the impact caused by walking will cause the piston rod 701 to drive the piston 702 to press the inner wall of the cylinder barrel 704 downwards, and the air pressure in the cylinder barrel 704 will increase, generating a force to push the piston 702 in the opposite direction, thereby achieving the purpose of buffering, and when the buffer block 703 reaches the buffer groove 706, the buffer spring 707 will be squeezed to give a reverse pushing force, thereby making the entire The buffer mechanism 7 is more efficient, thus solving the problem of existing knee and hip arthritis orthoses. When in use, since the orthosis itself has a certain weight, when the patient walks after wearing it, the body will bear the impact of the weight of the orthosis, which is extremely disadvantageous for patients with knee and hip arthritis. The patient's joints are already fragile due to inflammation. The additional impact will aggravate the wear of the articular cartilage, causing the pain to become more frequent and severe, which not only reduces the patient's ability and comfort in daily activities, but also may affect the patient's walking posture. Over time, it will cause more serious conditions such as muscle atrophy and joint deformity, further aggravating the condition and seriously affecting the patient's quality of life and rehabilitation process.
