Description

Technical Field

[0001] The utility model relates to the field of medical technology, and more specifically, to a rehabilitation function exercise device for preventing dislocation and adjustable after hip joint replacement surgery. Background Art

[0002] Clinically in hospitals, after patients undergo artificial hip joint replacement surgery, it is usually required that the hip flexion angle of the affected limb of the patient is less than 90 degrees, the affected limb is avoided from adduction and internal rotation, and the lower limbs are kept in an abducted neutral position when lying in bed to prevent the hip joint prosthesis from dislocating after surgery. On the basis of meeting the body position standard, the patient is then guided to perform subsequent rehabilitation function exercises of the hip and knee joints such as flexion and extension exercises of the knee joint while lying in bed and weight-bearing activities when getting out of bed.

[0003] However, for existing rehabilitation function exercise auxiliary tools, due to the lack of adjustment of the flexion angle of the hip and knee joints and the limitation of the ankle joint of the foot, it is easy for the patient's affected limb to have excessive hip flexion and adduction and internal rotation during the exercise process, resulting in the dislocation of the hip joint prosthesis. For example, clinically, it is common to use a triangular pillow as an abduction brace to keep the lower limbs in an abducted neutral position and avoid excessive adduction of the hip joint of the affected limb. However, the use effect of the triangular pillow is not only related to factors such as the placement position and the size of the pillow, but also cannot be used during the rehabilitation exercise process when getting out of bed. More importantly, it cannot accurately adjust the angle of the hip flexion and knee flexion body position of the patient, thus affecting the postoperative rehabilitation exercise effect.

A limit belt 600 is provided on one of the limit sleeve rings 500 for moving around the corresponding lower limb of the patient and buckling with the limit sleeve ring 500 to limit the corresponding outer telescopic rod 100 and inner telescopic rod 300 on both sides of the patient's lower limb. A hook surface 700 of the belt magic tape is provided at one end of the limit belt 600 close to the limit sleeve ring 500, and a hair surface 800 of the belt magic tape that is adhesively engaged with the hook surface 700 of the belt magic tape is provided at the end of the limit belt 600 far from the limit sleeve ring 500 to firmly limit the corresponding outer telescopic rod 100 and inner telescopic rod 300 on both sides of the patient's lower limb to prevent dislocation. During the use process, under the connection limitation of the outer knee flexion angle adjuster 200 of the outer support adjuster 31 on the two corresponding outer telescopic rods 100,With the connection of the inner knee flexion angle adjuster 400 of the inner support adjuster 32 to the two corresponding inner telescopic rods 300 defined, and with the connection of the extension angle adjuster 33 of the lower limb position limiting structure 3 to the two inner telescopic rods 300 at the upper ends on both sides defined, according to the body type requirements of the patient, after adjusting the lengths of the outer telescopic rod 100 and the inner telescopic rod 300 to the predetermined lengths, then place the corresponding outer telescopic rod 100 together with the outer knee flexion angle adjuster 200 and the corresponding inner telescopic rod 300 together with the inner knee flexion angle adjuster 400 on the inner and outer sides of the corresponding lower limbs of the patient respectively. At this time, the ankle limiting structure 4 extends to the ankle part of the patient and wraps the sole of the patient's foot to play a supporting and limiting role. Then, under the limiting action of the limiting collar 500 of the fixing belt body 34, during the process of pulling the movable end of the limiting belt 600 to move around the lower limb of the patient, it sequentially passes through the eyelets of the corresponding limiting collar 500. After the movable end of the limiting belt 600 passes through the eyelet of a limiting collar 500 connected to its fixed end, by adjusting the tightness of the limiting belt 600 to the predetermined tightness and then pulling the limiting belt 600 to move in the opposite direction, while the limiting belt 600 is buckled with the limiting collar 500, paste the hook surface 700 of the belt body magic tape and the fluff surface 800 of the belt body magic tape together with each other, so as to firmly place the corresponding outer telescopic rod 100 together with the outer knee flexion angle adjuster 200 and the corresponding inner telescopic rod 300 together with the inner knee flexion angle adjuster 400 on the inner and outer sides of the corresponding lower limbs of the patient. Then, through the waist belt structure 1, firmly limit the hip flexion angle adjuster 2 together with the lower limb position limiting structure 3 and the ankle limiting structure 4 on the waist of the patient. At this time, according to the need, by adjusting the movable end of the hip flexion angle adjuster 2 to extend to the predetermined angle, use the movable end of the hip flexion angle adjuster 2 to drive the corresponding outer telescopic rod 100 together with the upper body of the patient to extend to the predetermined angle to accurately adjust the hip flexion position angle of the patient. Under the limiting action of the outer telescopic rod 100 and the inner telescopic rod 300 at the upper end, by adjusting the movable ends of the corresponding outer knee flexion angle adjuster 200 and the inner knee flexion angle adjuster 400 respectively, drive the outer telescopic rod 100 and the inner telescopic rod 300 at the lower end together with the calf of the patient to extend to the predetermined angle, and, by adjusting the opening angle of the extension angle adjuster, adjust the opening angle between the two inner telescopic rods 300 at the upper end together with the two lower limbs of the patient to the predetermined angle, so as to accurately adjust the knee flexion position angle of the patient to keep the patient's lower limbs in the abduction neutral position posture, which can effectively ensure the hip flexion and knee flexion rehabilitation exercise effect of the patient. Using the mutual cooperation of the outer telescopic rod 100, the inner telescopic rod 300, the outer knee flexion angle adjuster 200, and the inner knee flexion angle adjuster 400 to limit the lower limb position of the patient can effectively reduce the contact area with the patient's lower limbs.

And,During use, through the mutual cooperation of the belt structure 1 and the fixing belt body 34, the hip flexion angle adjuster 2 and the lower limb position limiting structure 3 can be firmly limited on the patient's body to prevent the dislocation of the hip joint prosthesis; in addition, through the ankle limiting structure 4, the position of the patient's ankle can also be limited, so that the patient's sole can be vertically placed relative to the limb, thereby playing the role of preventing foot drop and preventing the affected limb from adducting and internally rotating.,

[0025] In this embodiment, the ankle limiting structure 4 includes an ankle angle adjuster 41 provided at one end of the corresponding outer telescopic rod 100 and inner telescopic rod 300 away from the corresponding outer knee flexion angle adjuster 200 and inner knee flexion angle adjuster 400. On the ankle angle adjuster 41, there is a limiting plate 42 that can be adjusted along with the movable end of the ankle angle adjuster 41 to limit the patient's ankle to avoid foot drop of the ankle joint and adduction and internal rotation of the affected limb. On the limiting plate 42, there is an elastic band 43 for firmly binding the patient's sole to the limiting plate 42. During use, after the ankle limiting structure 4 extends to the patient's ankle and covers the patient's sole, by adjusting the ankle angle adjuster 41 of the ankle limiting structure 4 to drive the limiting plate 42 to move the patient's sole, the patient's sole can be in a vertical state with the lower limb. Then, the patient's sole is firmly bound to the limiting plate 42 through the elastic band 43 to achieve firm limitation of the patient's ankle, thereby playing the role of preventing foot drop and preventing the affected limb from adducting and internally rotating.,

[0026] In this embodiment, on the side wall and bottom of the limiting plate 42, there is a hollow opening 5 for exposing the patient's ankle and heel to increase air circulation and reduce pressure sores on the foot skin; on the inner wall of the limiting plate 42, there is a soft cushion 6 for increasing the patient's comfort and preventing pressure sores caused by the hard contact between the patient's foot and the limiting plate 42. During use, through the hollow opening 5, the compressed parts such as the patient's ankle and heel can be fully exposed, which is not only convenient for medical staff to observe the skin condition of the patient's ankle and heel, but also can increase air circulation to reduce pressure sores on the foot skin; through the soft cushion 6, the patient's comfort can be increased to prevent pressure sores caused by the hard contact between the patient's foot and the limiting plate 42.,

[0027] In this embodiment, the hip flexion angle adjuster 2, the extension angle adjuster 33, the outer knee flexion angle adjuster 200, the inner knee flexion angle adjuster 400, and the ankle angle adjuster 41 are all SH-032 type adjustable chucks.,

[0028] In this embodiment, the belt structure 1 includes cushion bodies 11 detachably attached to both side ends of the patient's waist.

The elastic limiting component 12 further includes an adjusting buckle 160 provided on the elastic belt 140 for adjusting the length of the elastic belt 140 to adapt to the patient's use. During the use process, after placing the corresponding hip flexion angle adjuster 2 together with the lower - limb position limiting structure 3 and the adjusting rod 13 on both side ends of the patient's waist through the cushion body 11 of the belt structure 1, the snap sub - buckle 130 of the elastic limiting component 12 is snap - connected to the corresponding snap mother - buckle 150, so that the corresponding sides of the two cushion bodies 11, the corresponding connecting belt 120, the snap sub - buckle 130, the snap mother - buckle 150, and the elastic belt 140 are connected together. Then, according to the needs, the corresponding elastic belt 140 is adjusted to an appropriate tightness through the adjusting buckle 160, so as to stably limit the cushion body 11 together with the hip flexion angle adjuster 2, the adjusting rod 13, and the lower - limb position limiting structure 3 on both side ends of the patient's waist. Then, according to the hip and knee conditions of the patient, the position of the adjusting rod 13 on the cushion body 11 is adjusted and changed to adjust the hip flexion angle adjuster 2 to a predetermined position to adapt to the use of the patient. The operation is simple, reliable, and the phenomenon of hip joint prosthesis dislocation is not likely to occur.

[0029] When this embodiment is specifically used, first, after placing the corresponding hip flexion angle adjuster 2 together with the lower limb position limiting structure 3 and the adjusting rod 13 on the corresponding two side ends of the patient's waist through the cushion body 11 of the belt structure 1, then snap the snap button 130 of the elastic limiting component 12 with the corresponding snap female button 150 to connect them together. Thus, the corresponding sides of the two cushion bodies 11, the corresponding connecting belts 120, the snap button 130, the snap female button 150, and the elastic belt 140 are connected together. Then, according to the needs, adjust the corresponding elastic belt 140 to an appropriate tightness through the adjusting buckle 160, so as to firmly limit the cushion body 11 together with the hip flexion angle adjuster 2, the adjusting rod 13, and the lower limb position limiting structure 3 on the two side ends of the patient's waist. Then, according to the hip and knee conditions of the patient, adjust the position of the adjusting rod 13 on the cushion body 11 to adjust the hip flexion angle adjuster 2 to a predetermined position to adapt to the use of this patient. The operation is simple and reliable, and the phenomenon of hip joint prosthesis dislocation is not likely to occur. Secondly, under the connection and limitation of the outer knee flexion angle adjuster 200 of the outer support adjuster 31 to the two corresponding outer telescopic rods 100, and under the connection and limitation of the inner knee flexion angle adjuster 400 of the inner support adjuster 32 to the two corresponding inner telescopic rods 300, and under the connection and limitation of the extension angle adjuster 33 of the lower limb position limiting structure 3 to the two inner telescopic rods 300 at the upper two sides, according to the body type requirements of the patient, after adjusting the lengths of the outer telescopic rod 100 and the inner telescopic rod 300 to a predetermined length, then place the corresponding outer telescopic rod 100 together with the outer knee flexion angle adjuster 200 and the corresponding inner telescopic rod 300 together with the inner knee flexion angle adjuster 400 on the inner and outer sides of the corresponding lower limbs of the patient respectively. At this time, the ankle limiting structure 4 extends to the ankle part of the patient and wraps the patient's sole to play a supporting and limiting role. Then, under the limiting effect of the limiting collar 500 of the fixing belt body 34, when pulling the movable end of the limiting belt 600 to move around the patient's lower limb, it sequentially passes through the eyelets of the corresponding limiting collar 500. After the movable end of the limiting belt 600 passes through the eyelet of a limiting collar 500 connected to its fixed end, after adjusting the tightness of the limiting belt 600 to a predetermined tightness and then pulling the limiting belt 600 to move in the opposite direction, while the limiting belt 600 is buckled with the limiting collar 500, paste the hook surface 700 of the belt body magic tape and the loop surface 800 of the belt body magic tape together, so as to firmly place the corresponding outer telescopic rod 100 together with the outer knee flexion angle adjuster 200 and the corresponding inner telescopic rod 300 together with the inner knee flexion angle adjuster 400 on the inner and outer sides of the corresponding lower limbs of the patient;Then, according to the requirements, by adjusting the movable end of the hip flexion angle adjuster 2 to extend to a predetermined angle, the movable end of the hip flexion angle adjuster 2 is used to drive the corresponding outer telescopic rod 100 together with the upper body of the patient to extend to a predetermined angle to accurately adjust the hip flexion position angle of the patient. Under the limiting action of the outer telescopic rod 100 and the inner telescopic rod 300 located at the upper end, by adjusting the movable ends of the corresponding outer knee flexion angle adjuster 200 and the inner knee flexion angle adjuster 400 respectively drive the outer telescopic rod 100 and the inner telescopic rod 300 located at the lower end together with the patient's calf to extend to a predetermined angle. Moreover, by adjusting the opening angle of the extension angle adjuster, the opening angle between the two inner telescopic rods 300 located at the upper end and the patient's lower limbs is adjusted to a predetermined angle, so as to accurately adjust the knee flexion position angle of the patient to keep the patient's lower limbs in an abducted neutral position, which can effectively ensure the hip flexion and knee flexion rehabilitation exercise effect of the patient. The mutual cooperation of the outer telescopic rod 100, the inner telescopic rod 300, the outer knee flexion angle adjuster 200, and the inner knee flexion angle adjuster 400 to limit the position of the patient's lower limbs can effectively reduce the contact area with the patient's lower limbs, thereby increasing the air circulation in the patient's skin area, and thus it is not easy to cause pressure sores on the patient's skin. Also, when in use, through the mutual cooperation of the belt structure 1 and the fixing strap body 34, the hip flexion angle adjuster 2 and the lower limb position limiting structure 3 can be firmly limited on the patient's body to prevent the occurrence of hip joint prosthesis dislocation; finally, by adjusting the ankle angle adjuster 41 of the ankle limiting structure 4 to drive the limiting plate 42 to push the patient's foot to move, so that the patient's foot is perpendicular to the lower limb, and then the patient's foot is firmly bound to the limiting plate 42 by the telescopic strap 43 to achieve firm limitation of the patient's ankle, thereby playing the role of preventing foot drop and preventing adduction and internal rotation of the affected limb.
