[0025] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified. Example
[0026] like Figure 1-Figure 7As shown, the utility model provides an adjustable angle orthosis for knee osteoarthritis, comprising a calf connector 1 and a thigh connector 2 meshed with the calf connector 1, a connecting seat 3 is arranged between the meshing ends of the calf connector 1 and the thigh connector 2, the ends of the calf connector 1 and the thigh connector 2 are rotatably connected to the connecting seat 3 through a rotating shaft, a connecting member rotation limiting component 4 is arranged on the outside of the connecting seat 3, the connecting member rotation limiting component 4 is simultaneously embedded in the meshing ends of the calf connector 1 and the thigh connector 2 to limit the rotation of the calf connector 1 and the thigh connector 2, an arc groove is provided at the meshing ends of the calf connector 1 and the thigh connector 2, the inner wall of the connecting seat 3 protrudes inwardly to form a synapse portion, the protrusion is nested in the arc groove of the calf connector 1 and the thigh connector 2, and the protrusion serves as the maximum limiting end of the connecting seat 3 to limit the movement of the calf connector 1 and the thigh connector 2.
[0027] A connecting hole is set in the middle of the connecting seat 3, and the connecting piece rotation limiting component 4 is movably connected to the connecting seat 3 through the connecting hole. The connecting piece rotation limiting component 4 includes a screw 41, a pressing plate 42 and an insertion rod 43. The screw 41 is threadedly connected in the connecting hole of the connecting seat 3, the pressing plate 42 is sleeved on the outside of the screw 41, and the insertion rod 43 is set on both sides of the inner wall of the pressing plate 42. The ends of the insertion rod 43 pass through the connecting seat 3 and are embedded in the arc grooves at the ends of the calf connecting piece 1 and the thigh connecting piece 2. After being embedded in the arc groove, the insertion rod 43 can cooperate with the connecting seat 3 to lock the meshing state of the calf connecting piece 1 and the thigh connecting piece 2, so that the calf connecting piece 1 and the thigh connecting piece 2 are kept in a straight state and kept locked, which is suitable for helping the legs to maintain a vertical state for a long time.
[0028] The ends of the insertion rod 43 are rounded. The rounded corners allow the ends of the insertion rod 43 to partially enter the arc grooves at the ends of the calf connector 1 and the thigh connector 2. When further pressed downward, the arc grooves can be pushed to rotate to the aligned position, thereby obtaining a certain degree of automatic correction capability. The diameter of the insertion rod 43 is consistent with the inner diameter of the arc grooves at the ends of the calf connector 1 and the thigh connector 2. After the insertion rod 43 completely enters the arc groove, it can contact the inner wall of the arc groove, thereby obtaining stable lateral support.
[0029] The connecting piece rotation limiting assembly 4 also includes a spring 44, which is sleeved on the outside of the screw 41, and the two ends of the spring 44 are respectively in contact with the screw 41 and the pressing plate 42. The spring 44 pushes the screw 41 and the pressing plate 42 at the same time by its own deformation, so that the screw 41 maintains a stable meshing relationship when rotating relative to the pressing plate 42, thereby preventing the connection between the screw 41 and the pressing plate 42 from vibrating and loosening due to long-term movement.
[0030] An annular recess is provided at the contact position between the pressing plate 42 and the spring 44, and the end of the spring 44 is nested in the annular recess. The annular recess on the pressing plate 42 can further limit the end of the spring 44, thereby preventing the spring 44 from being torsionally damaged due to the erroneous deflection of the screw 41 when the screw 41 rotates, thereby increasing the service life of the spring 44.
[0031] The inner sides of the calf connector 1 and the thigh connector 2 are respectively provided with a calf connector lining 5 and a thigh connector lining 6. The addition of the calf connector lining 5 and the thigh connector lining 6 prevents the calf connector 1 from directly contacting the user's legs, thereby improving the comfort when wearing. Magic straps 7 are provided at the ends of the calf connector 1 and the thigh connector 2. The magic straps 7 can bind the calf connector 1 and the thigh connector 2 to the user's thigh and calf respectively, and rotate synchronously with the swing of the thigh and calf.
[0032] The connecting piece rotation limiting assembly also includes an orthopedic protrusion, which is rotatably connected to the end of the screw. The magic strap cooperates with the screw to form a triangular fixing area. The screw continuously pushes the orthopedic protrusion to move laterally. During the lateral movement, the orthopedic protrusion corrects the movement of the bone joint to avoid incorrect deflection of the bone joint.
[0033] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
