Description

Ankle foot orthosis and ankle foot orthopedic shoes

Technical Field

The utility model belongs to the technical field of rehabilitation physiotherapy equipment, and particularly relates to an ankle-foot orthosis and an ankle-foot orthosis shoe adopting the ankle-foot orthosis.

Background

Drop foot, drop foot and pointed foot are terms used to describe the inability of the ankle joint to dorsiflex in plantar flexion (colloquially understood as the inability of the foot to lift normally) due to ankle dorsiflexion, so that the toe is facing downward and scraping the ground while walking, resulting in drop foot symptoms typically caused by stroke, cerebral palsy, surcharge nerve damage, multiple sclerosis and other non-neuropathic injuries. Ankle dorsiflexion motion refers to the action of hooking the foot upward, which is required to occur when the foot leaves the ground, particularly uphill and stepped, so that the foot does not drag on the ground. Foot drop makes walking difficult because the foot tends to drag on the ground, resulting in easy stumbling and instability and even inability to walk. Patients need to improve by exaggeratedly lifting the foot off the ground (known as "crotch-lifting compensatory gait") or by swinging the leg outward to leave the foot off the ground (known as "supination gait"), however long lasting such abnormal gaits can result in multiple joints and tissue damage and are detrimental to long term recovery.

Wearing ankle foot orthoses is a common method of improving foot drop. Conventional ankle and foot orthoses are generally injection molded integrally from rigid plastic, are invariable in shape or are custom made from thermoplastic after being cast using plaster, and have no joint structure capable of dynamic movement. The conventional ankle-foot orthosis is fixed at the position of the ankle foot in a direct contact manner when being worn, the ankle foot is fixed at a specific angle through the strong action of the hard material, and the plantar flexion and dorsiflexion functions of the ankle joint are completely limited. Although the foot drop symptom can be well improved, the normal plantar flexion and dorsiflexion movements of the ankle joint are completely limited, the magnitude of the adaptive plantar flexion resistance and dorsiflexion assistance can not be adjusted according to the individual condition of the patient, the patient still can not achieve stable and natural gait, still has very high falling risk, and can cause edema and hardening of the joint for a long time.

Therefore, it is particularly important how to solve the problem that the conventional ankle-foot orthosis completely limits the normal plantar flexion and dorsiflexion movements of the ankle joint and cannot adjust the magnitude of plantar flexion resistance and dorsiflexion assistance.

Example 1

As shown in fig. 1, the present embodiment provides an ankle-foot orthosis including a shoe holder 10 for coupling with a shoe body of a wearer, an accumulator 20 provided on the shoe holder, and a shank holder 30 provided on the accumulator; wherein the shank anchor 30 includes a support bar 31, the energy storage device 20 is mounted to one side of the shoe holder 10, and the shank anchor 30 is mounted to the energy storage device 20 through the support bar 31. The ankle-foot orthosis is stably bound with the leg of the wearer by being fixedly connected with the shoe body of the wearer through the shoe fixing device 10 and being bound on the calf of the wearer through the calf fixer 30. In this embodiment, the energy accumulator 20 is located at the side edge of the shoe body of the wearer, and the support bar 31 is led out from one end of the energy accumulator 20 and bent to make a part of the support bar located in front of the lower leg and close to the lower leg of the wearer, so as to strengthen ergonomics and save wearing space, thereby enhancing stability of the ankle foot orthosis for assisting the wearer to lift the foot and enhancing aesthetic property after wearing. In specific practice, the support bar needs to have a certain rigidity and toughness, so the support bar in this embodiment is made of carbon fiber rods, but the support bar is not limited to being made of carbon fiber materials.

As shown in fig. 2 and 3, the accumulator 20 includes a housing 21, a cam 22, a tube 23, an elastic member 24, and an adjusting member 25. In this embodiment, the housing 21 and the tube 23 are mutually communicated and form a receiving cavity, and the cam 22, the elastic member 24 and a part of the adjusting member 25 are all accommodated in the receiving cavity. One end of the elastic member 24 interacts with the cam 22, the other end of the elastic member is connected with the adjusting member 25, and the initial pretightening force of the elastic member 24 is adjusted through the adjusting function of the adjusting member 25, so that the aim of adjusting the ankle foot orthosis according to the weight or the requirements of different wearers is achieved, and the application range of the ankle foot orthosis is widened. In order to reduce the weight, a plurality of weight reducing holes may be formed in the cam 22.

Further, the elastic member 24 includes an elastic member 241 and a movable pressing head 242, which are accommodated in the pipe body 23, and the movable pressing head 242 is provided with a rotating shaft 243 along a transverse direction thereof, and the rotating shaft 243 is rotatably disposed on the roller 244. Wherein, the elastic piece 241 is a compression spring, the cam 22 is in a cam structure, and the roller 244 rolls reciprocally along the outer edge surface of the involute section of the cam 22; preferably, the cam structure of the cam 22 is in an axisymmetric structure, and the symmetry axis of the cam structure is perpendicular to the central line of the tube 23, so that the roller 244 is driven to roll on the outer edge surface of the cam in a relatively labor-saving manner. Specifically, the cam structure is provided with an equal-diameter arc section and an involute section, and when the roller rolls along the outer edge surface of the equal-diameter arc section, the roller does not act on the compression spring at the moment and is in a free state; when the roller rolls along the outer edge surface of the involute section, the roller can act on the compression spring or the compression spring can release pressure to act on the roller. In specific practice, when the wearer stands upright and walks and kicks the foot on the legs, namely the wearer drives the shell to rotate around the direction of increasing the included angle relative to the shoe fixing device, the shell is driven to rotate forward relative to the cam, so that the driving roller rolls forward along the outer edge surface of the involute section of the cam, the roller is caused to squeeze the compression spring, and therefore the energy storage effect is achieved; when the foot part leaves the ground in the walking process of the wearer, the compression spring releases pressure to drive the roller to roll reversely along the outer edge surface of the involute section of the cam, so that the shell reversely rotates relative to the cam to drive the dorsum of the wearer to bend, thereby helping the wearer to complete the foot lifting action and driving the wearer to complete the foot lifting action, and further realizing the foot lifting action for assisting the stability of the wearer. It should be noted that, the arrangement of the equal-diameter arc-shaped section on the cam structure of the embodiment is convenient for the wearer to sit and squat without limiting the free movement of the foot of the wearer relative to the local range of the leg.

Further, the adjusting member 25 includes a pressing block 251, a knob 252, and a capped press stud 253; wherein, the press block 251 is fixed at the opening of the pipe body 23 by a pin, and the threaded end of the knob 252 passes through the press block 251 to be abutted against the capped press nail 253 by a threaded hole formed on the press block 251. In this embodiment, the roller 244 abuts against the outer edge surface of the cam, the movable pressure head 242 abuts against one end of the compression spring, the other end of the compression spring abuts against the pressing nail 253 with the cap, and the adjusting knob 252 rotates relative to the pressing block 251 to drive the pressing nail 253 with the cap to pressurize or decompress the compression spring to cause deformation of the compression spring, so as to adjust the pretightening force of the compression spring in the initial state. In specific practice, the knob can be provided with three gear identifiers so as to be convenient for the wearer to accurately adjust. It should be noted that in other embodiments, the adjusting member may not have a knob, which means that the adjusting member does not have a function of adjusting the pretightening force of the elastic member. The energy accumulator is provided with the adjusting piece, and a wearer can adjust the initial pretightening force of the energy accumulator through the adjusting piece so as to achieve the magnitude suitable for the plantar flexion resistance and dorsiflexion assistance required by the wearer at the moment. The magnitude of plantar flexion resistance and dorsiflexion assistance can be adjusted to adapt to different symptom degrees of different patients and different periods of rehabilitation requirements of the same patient.

In particular practice, when the wearer steps on his or her legs upright and walking, the calf holder 30 drives the housing 21 to rotate relative to the cam 22, so that the elastic member 24 stores energy; when the foot leaves the ground during the walking process of the wearer, the elastic piece 24 automatically releases energy due to no external force, and can drive the shell 21 to rotate towards the opposite direction relative to the cam 22, so as to drive the dorsum of the wearer to bend, thereby helping the wearer to complete the foot lifting action and ensuring the gait stability of the wearer wearing the ankle-foot orthosis during the walking process. The energy accumulator of the embodiment has the characteristics of simple structural design on the basis of energy storage and energy release characteristics.

As shown in fig. 3 and 4, the casing 21 is provided with a through hole 211 extending along the length direction of the pipe body 23, and the inner cavity of the pipe body 23 is communicated with the accommodating cavity of the casing 21 through the through hole 211, so that the rotating shaft 243 passes through the avoiding through hole 211 and is rotationally connected with the roller 244. In this embodiment, the through holes 211 are disposed along the length direction of the tube 23, so as to limit the moving direction of the roller 244, so that the compression force applied by the roller 244 to the elastic member 241 is consistent with the length direction of the tube 23, and the elastic member 241 is ensured to be freely stretched. Of course, the accommodating cavity of the shell is provided with a clearance position for the roller to move.

As shown in fig. 1, the shank holder 30 includes a support bar 31, an arc plate 32 connected to the support bar, and binding bands 33 respectively provided at both ends of the arc plate, and the two binding bands 33 achieve binding of the wearer's shank through a locker. In this embodiment, the curvature of the arcuate plate 32 is approximately the same as the wearer's calf so that the arcuate plate 32 fits snugly against the wearer's calf. In specific practice, the locking device can include a male buckle and a female buckle which are respectively arranged on two binding belts, wherein the female buckle on one binding belt is bound with the pressing knob on the female buckle through the connecting strip, so that when the shank fixer is used for binding the shank of a wearer, the shank is arranged in the shank fixer through the opening parts of the two binding belts, after the female buckle is buckled into the male buckle, the connecting strip is rotated and tightened according to the indicated direction after the pressing knob is pressed, and the binding and fixing of the two binding belts to the shank of the wearer are realized. Of course, other embodiments may also achieve binding of the wearer's calf by providing velcro on both straps so that the bonding of the two straps is achieved.

As shown in fig. 5, the arc plate 32 extends along the vertical direction to form an open clamping groove 321, and an elastic buckle 322 is disposed on one side of the open clamping groove 321 opposite to the opening.
