Description

Technical Field

[0001] The invention relates to the technical field of orthotics, in particular to an orthopedic foot and ankle orthopedic fixator. Background Art

[0002] Orthotics are a general term for external devices that are installed on the limbs, trunk and other parts of the human body. Their purpose is to prevent or correct deformities of the limbs and trunk or to treat bone and joint and neuromuscular diseases and compensate for their functions. The main function of lower limb orthotics is to support body weight, assist or replace limb functions, limit unnecessary activities of lower limb joints, maintain lower limb stability, improve posture when standing and walking, and prevent and correct deformities.

[0003] The bottom of the traditional foot and ankle orthosis is equipped with an orthotic insole to support the arch of the foot, leaving no space for perspiration in the toes and soles of the feet. Therefore, sweat is prone to odor in the soles of the feet during wearing. After surgery, it is usually not recommended for patients to take off the orthosis for one month, which makes it impossible to clean the feet. In addition, the swelling of the affected limb after surgery will cause the orthosis to increase the pressure on the sole of the foot, affecting blood circulation, which not only aggravates perspiration, but also creates conditions for fungal growth, increasing the risk of odor and infection.

[0004] After searching, a foot and ankle orthopedic fixator for orthopedics is disclosed in the publication number: CN114587736B, which relates to the technical field of orthopedics. The present invention comprises: a base, a shock absorbing mechanism is fixedly connected to the top of the base, and the shock absorbing mechanism is used for ventilation and shock absorbing operation; a rolling mechanism; a pushing mechanism; and a massage mechanism. When the present invention is in use, the shock absorbing mechanism and the rolling mechanism are operated by the wearer's walking, and the vibration generated by the wearer's walking is buffered by the operation of the shock absorbing mechanism, while the air on the wearer's sole is ventilated, and the wearer's sole is massaged by the operation of the rolling mechanism, which can effectively ventilate the wearer's sole, prevent the wearer from wearing the sole for a long time, resulting in bad smell on the sole and sweat on the sole, improve comfort, and prevent the wearer's sole muscles from being unable to relax and causing damage to the sole, thus providing good protection for the wearer.

[0005] In the above application, dust will adhere to the soles of the foot orthoses during use, and some patients with severe foot deformities or injuries cannot remove the foot orthoses when lying in bed to prevent the foot from shifting, so the foot orthoses are easy to dirty the sheets when used in bed, which brings certain inconveniences.

[0017] Working principle: When in use, the patient fits the foot and leg to the sole and the fixing plate respectively, and then fixes the foot and leg of the patient by the fixing belt. Before walking, the patient controls the operation of the electric push rod by pressing the remote control. The electric push rod contracts and pulls the lower slider to slide, so that the bracket 1 and the bracket 2 rotate, and the lifting component descends to push the support plate down and make its bottom end lower than the bottom end of the sole, so that when the patient walks, the support plate contacts the ground to reduce the contact area, and at this time, the sole is suspended in the air, so as to avoid the sole from directly contacting the ground and adhering too much dust, and when the patient lies on the bed, the electric push rod is controlled by the remote control to extend and retract, and the lifting component rises to drive the support plate to be stored in the shell, and when the support plate rises, the air bag 1 is squeezed, and the gas inside the air bag 1 is passed into the inner part of the outer cylinder through the ventilation pipe, so as to push the inner rod body to extend, so that the baffle slides to the bottom of the shell, so as to cover the support plate and prevent the dust at the bottom of the support plate from falling to the bed body, so as to effectively reduce the pollution of the bed sheet by the dust adhering to the bottom of the orthosis when the patient is resting, on the basis of meeting the patient's long-term wearing of the orthosis.

[0018] When the patient walks, the extrusion plate slides upward against the ground to squeeze airbag 2, so that the gas inside airbag 2 is discharged from the air outlet end into the interior of the shell, and flows upward from the air vent to blow toward the soles of the patient's feet; when the extrusion plate is separated from the ground, airbag 2 recovers and expands, and the airflow channel is blocked by the sphere, so that the external gas enters the interior of airbag 2 through the one-way air inlet valve to realize circulation ventilation, thereby alleviating the problem of bad odor on the soles of the feet and sweat on the soles of the feet caused by long-term wearing of the patient, improving comfort, and the inner layer can be directly disassembled and replaced, so as to keep the surface of the inner layer clean and tidy, and facilitate cleaning, thereby effectively solving the problem of bad odor on the soles of the feet and sweat on the soles of the feet and dust adhesion.

[0019] When the ventilation effect of the breathable component needs to be turned off in cold weather, the extrusion plate is pressed into the inside of the installation slot, and then the sliding seat is pushed to move to the notch. The limit frame extends out of the sliding slot two through the elastic force of spring two, and passes through the notch to press against the extrusion plate, thereby fixing the extrusion plate inside the installation slot, thereby turning off the ventilation function of the breathable component and avoiding discomfort to the soles of the patient's feet caused by air flow in cold weather.

[0020] The present invention provides an orthopedic foot and ankle orthopedic fixator, which has the following beneficial effects:

[0021] 1. The present invention reduces the contact area between the support plate and the ground, thereby reducing the adhesion of dust. When the patient lies on the bed, the support plate is stored inside the shell and the shell is closed by the baffle to prevent the dust at the bottom of the support plate from falling onto the bed. In this way, while meeting the patient's need to wear the orthosis for a long time, the dust adhering to the bottom of the orthosis can effectively reduce the pollution of the bed sheet to the bed sheet when the patient is resting.

[0022] 2. The present invention achieves the effect of wearing the orthosis for correction through the cooperation of the sole, the fixing plate and the fixing belt, and the sole adopts a detachable inner layer and outer layer design. After the inner layer is dirty during use, it can be manually disassembled for cleaning or replacement.

[0023] 3. The present invention uses the driving force applied to the squeezing plate by the ground when the patient walks, so that the squeezing plate can automatically squeeze the second airbag, thereby driving the flow of air in the sole area for ventilation, effectively reducing foreign matter on the sole and reducing the production of sweat, and cushioning to a certain extent through the second airbag, thereby reducing the impact force on the foot when the patient moves.

[0024] 4. The present invention clamps the extrusion plate through the limit frame to close the ventilation function of the breathable component, thereby preventing air flow from causing discomfort to the soles of the patient's feet in cold weather, and realizing flexible adjustment of the breathable component to meet the use requirements of different seasons.

DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please see attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides an orthopedic foot and ankle orthosis fixator, comprising a sole 1, the sole 1 comprising an annular outer layer 101 and a plate-shaped inner layer 102, the outer layer 101 and the inner layer 102 being detachably connected by screws, the upper surface of the outer layer 101 being fixedly connected with an arc-shaped fixing plate 2, the side wall of the fixing plate 2 and the upper surface of the outer layer 101 being respectively fixedly provided with a plurality of fixing belts 3, the surface of the inner layer 102 being provided with a plurality of openings 103, the interior of the opening 103 being fixedly connected with a shell 104, the upper surface of the shell 104 being provided with air vents 105 distributed in a matrix, the inner wall of the shell 104 being slidably connected with a support plate 4, the upper part of the support plate 4 being provided with a lifting assembly 5, the lifting assembly 5 being used to adjust the height of the support plate 4, the bottom of the inner layer 102 Several dustproof components 6 are installed, and the dustproof components 6 are cross-arranged with the openings 103. The dustproof components 6 are used to close the shell 104. The sole 1 and the fixing plate 2 are made of hard materials. A honeycomb insole is fixedly provided on the upper surface of the inner layer 102. The shape and height of the honeycomb insole vary according to the orthopedic purpose. A sponge layer is fixedly provided on the inner wall of the fixing plate 2. The honeycomb insole and the sponge layer are used to improve the patient's comfort when wearing. The honeycomb insole has good ventilation and air permeability effects, which improves the ventilation and air permeability effects of the sole area, so that the sole of the patient has good air permeability when not walking, reduces the generation of sweat, and reduces the risk of odor and infection. Each set of fixing plates 2 is composed of two straps, and the two straps are snap-connected by Velcro, which belongs to the prior art and will not be described here.

[0038] Specifically, the outer layer 101 is used to connect the fixing plate 2, and the inner layer 102 is used to support the foot. The detachable inner layer 102 can be removed for cleaning or replacement after being soiled by a patient who does not need to perform orthotics on the soles of the feet. The fixing plate 2 is used to support the legs, and the fixing belt 3 is used to fix the patient's feet and legs and cooperate with the sole 1 and the fixing plate 2 for orthotics. The lifting component 5 is used to adjust the height of the support plate 4. When the patient walks, the lifting component 5 drives the support plate 4 to descend, and the support plate 4 replaces the sole 1 to contact the ground, thereby reducing the contact area and reducing the adhesion of dust. When the patient lies on the bed, the lifting component 5 drives the support plate 4 to rise to the inside of the shell 104. At this time, the shell 104 is closed by the dustproof component 6 to prevent dust on the surface of the support plate 4 from falling onto the bed sheets, thereby reducing or even avoiding the contamination of the bed sheets by dust adhered to the bottom of the orthosis, meeting the needs of patients with certain severe foot deformities or injuries for long-term wearing.

[0039] Please see attached Figure 3 -Attached Figure 4 The lifting assembly 5 includes a slide 51, a bracket 1 52 and a bracket 2 53. The slide 51 is opened on the upper surface of the support plate 4. The centers of the bracket 1 52 and the bracket 2 53 are connected by an axis rotation. The top of the bracket 1 52 is connected to the inner top wall of the shell 104 by an axis rotation. The bottom end of the bracket 1 52 is connected to a lower slider 54 by an axis rotation. The outer wall of the lower slider 54 is connected to the inner wall of the slide 51 by sliding. The top of the bracket 2 53 is connected to an upper slider 55 by an axis rotation. The upper surface of the upper slider 55 is connected to the inner top wall of the shell 104 by sliding. The bottom end of the bracket 2 53 is connected to the upper surface of the support plate 4 by an axis rotation. The interior of the slide 51 is fixedly connected with An electric push rod 56, the driving end of which is fixedly connected to the side wall of the lower slider 54, the electric push rod 56 is electrically connected to a controller, the controller is electrically connected to a Bluetooth receiving module, the Bluetooth receiving module is wirelessly connected to a Bluetooth remote control, the electric push rod 56 is electrically connected to a power module, the power module is used to provide functions for the electric push rod 56, the power module and the controller are fixedly arranged on the outside of the fixing plate 2 or embedded in the inner layer 102, and the remote control allows the patient to operate independently without human assistance, and when there are family members around, the family members can wear shoe covers to avoid dust, and it is convenient to walk in rainy days to avoid dirtying the orthosis.

[0040] Specifically, the Bluetooth remote control is used to cooperate with the Bluetooth receiving module to remotely control the operation of the electric push rod 56 to achieve the adjustment of the lifting function of the lifting assembly 5. The electric push rod 56 contracts and pulls the lower slider 54 to slide toward the electric push rod 56, and drives the bracket 1 52 and the bracket 2 53 to rotate and the upper slider 55 to slide toward the electric push rod 56, thereby pushing the support plate 4 down out of the shell 104. When the electric push rod 56 is extended, the lower slider 54 slides in the direction away from the electric push rod 56, and drives the bracket 1 52 and the bracket 2 53 to rotate in the opposite direction and the upper slider 55 to slide in the direction away from the electric push rod 56, thereby driving the support plate 4 to be stored in the interior of the shell 104, thereby achieving the lifting and lowering adjustment of the support plate 4 with the sole 1 as the reference layer.

[0041] Please see attached Figure 3 -Attached Figure 5 The dustproof component 6 includes a plurality of airbags 61 and baffles 62. The lower surface of the airbag 61 is fixedly connected to the upper surface of the support plate 4. The baffle 62 is located below the inner layer 102. Both sides of the baffle 62 are slidably connected with L-shaped fixing seats 63. The upper surface of the fixing seat 63 is fixedly connected to the lower surface of the inner layer 102. Grooves 64 are respectively provided on both sides of the baffle 62. The inner side wall of the groove 64 is fixedly connected with a tension spring 65. The other end of the tension spring 65 is fixedly connected to the inner wall of the fixing seat 63. The inner wall of the fixed seat 63 is fixedly connected to the outer cylinder 66, and a seal 67 is installed inside the outer cylinder 66. The inner wall of the seal 67 is fixedly provided with an inner rod 68. The outer wall of the inner rod 68 is slidably connected to the inner wall of the outer cylinder 66. One end of the inner rod 68 located outside the outer cylinder 66 is fixedly connected to the inner wall of the groove 64. The outer walls of the outer cylinder 66 and the airbag 61 are jointly fixedly provided with a ventilation pipe 69. The ventilation pipe 69 runs through the shell 104. The seal 67 adopts a rubber sealing ring or a sealing piston ring.

[0042] Specifically, the fixing seat 63 is used to connect the inner layer 102. When the support plate 4 descends, the squeezing of the airbag 61 is gradually reduced. The baffle 62 is slidably stored inside the fixing seat 63 by the pulling force of the tension spring 65, so that the baffle 62 and the support plate 4 are staggered. The vent pipe 69 is used to connect the airbag 61 and the outer cylinder 66. The seal 67 is used to seal the gap between the inner rod body 68 and the outer cylinder body 66 to prevent the internal gas of the outer cylinder body 66 from escaping. When the support plate 4 is stored inside the shell 104, it cooperates with the shell 104 to squeeze the airbag 61, so that the internal gas of the airbag 61 enters the interior of the outer cylinder body 66 and pushes the inner rod body 68 to move outward. When the inner rod body 68 moves, it drives the baffle 62 to move to the bottom of the shell 104, thereby closing the shell 104 to cover the support plate 4 and prevent the dust attached to the bottom of the support plate 4 from falling onto the bed.

[0043] Please see attached Figure 6The baffle 62 includes an outer frame 621, and the inner wall of the outer frame 621 is rotatably connected to a rotating member 622 via a torsion spring shaft.

[0044] Specifically, the rotating member 622 is tightly pressed against the lower surface of the inner layer 102 by the torsion force of the torsion spring shaft, and the rotating member 622 can be pushed to rotate when the support plate 4 descends, so as to prevent the baffle 62 from being stored in time and blocking the descent of the support plate 4.

[0045] Please see attached Figure 7 -Attached Fig.10 A mounting groove 7 is provided on the lower surface of the support plate 4, and a breathable component 8 is installed inside the mounting groove 7. The breathable component 8 includes an airbag 2 801. The upper surface of the airbag 2 801 is fixedly connected to the inner top wall of the mounting groove 7. An extrusion plate 802 is provided below the airbag 2 801. The outer wall of the extrusion plate 802 is slidably connected to the inner wall of the mounting groove 7. An air outlet 803 is fixedly provided on the upper surface of the airbag 2 801. The top of the air outlet 803 passes through the support plate 4. A conical airflow channel 804 is provided inside the air outlet 803. A sphere 805 is provided on the inner wall of the airflow channel 804. The sphere 805 is a steel ball. A breathable mesh plate 806 is fixedly connected to the inner wall of the airflow channel 804. Rectangular channels 10 are provided on the surfaces of the airbag 2 801 and the extrusion plate 802 corresponding to the slide groove 51. The rectangular channel 10 is used for the extrusion plate 802 to pass through the slide groove 51 to extrude the airbag 2 801.

[0046] Specifically, the squeezing plate 802 is used to slide upward and squeeze the airbag 2 801 when it contacts the ground, which plays a certain buffering role. At the same time, the gas inside the airbag 2 801 can enter the interior of the shell 104 from the air outlet end 803, and then flow outward from the air hole 105, and pass through the air permeable channel of the honeycomb insole to contact the sole of the patient's foot, thereby accelerating the flow of air in the sole area to achieve ventilation, reduce the odor of the sole and reduce the production of sweat. The mesh holes on the surface of the breathable mesh plate 806 are used for air flow, and the breathable mesh plate 806 restricts the sphere 805 to prevent the sphere 805 from escaping from the air flow channel 804. When the airflow inside the airbag 2 801 passes through the air outlet end 803, it flows along the air flow channel 804. When the airflow flows upward, it pushes the sphere 805 to roll upward to open the air flow channel 804. When the gas stops flowing upward, the sphere 805 blocks the air flow channel 804 to prevent the gas in the sole 1 from being inhaled by the inflated airbag.

[0047] Please see attached Fig. 9 A one-way air intake valve 807 is fixedly provided on the side wall of the airbag 2 801, and a mounting port is provided on the side wall of the support plate 4 corresponding to the one-way air intake valve 807. The outer wall of the one-way air intake valve 807 is fixedly connected to the inner wall of the mounting port, and a filter screen 9 is fixedly connected to the inner wall of the mounting port.

[0048] Specifically, when airbag 2 801 expands, air is taken in through the one-way air inlet valve 807, and when airbag 2 801 contracts, the one-way air inlet valve 807 automatically closes to prevent air flow out. External air is filtered by the filter 9 and enters the interior of airbag 2 801 through the one-way air inlet valve 807, thereby preventing dust and impurities from entering the interior of airbag 2 801 to a certain extent.

[0049] Please see attached Figure 7 The ventilation component 8 also includes two groups of sliding grooves 808 and two groups of notches 814. The sliding grooves 808 are arranged at both ends of the support plate 4, and the notches 814 are arranged at the centers of both ends of the support plate 4. The sliding grooves 808 are located on one side of the notch 814. The inner wall of the sliding grooves 808 is slidably connected with a sliding seat 809. The outer wall of the sliding seat 809 and the inner wall of the sliding grooves 808 are jointly fixedly connected with a spring 810. The surface of the sliding seat 809 is provided with a sliding groove 811. The inner wall of the sliding grooves 811 is slidably connected with an L-shaped limiting frame 812. The inner wall of the limiting frame 812 and the inner wall of the sliding grooves 811 are jointly fixedly connected with a spring 813.

[0050] Specifically, the sliding seat 809 is restricted by the elastic force of the spring 1 810, so that the limit frame 812 is staggered with the notch 814, so as to prevent the limit frame 812 from extending from the notch 814 to affect the normal sliding of the extrusion plate 802. The limit frame 812 is tightly pressed against the inner wall of the sliding groove 1 808 by the elastic force of the spring 2 813. In cold weather, sweat on the soles of the feet usually decreases, and the air flow on the sole 1 will cause the patient to feel cold. Therefore, it is necessary to turn off the ventilation function of the breathable component 8. By pressing the extrusion plate 802 to the inside of the mounting groove 7, and then pushing the sliding seat 809 to move to the notch 814, the limit frame 812 extends out of the sliding groove 2 811 by the elastic force of the spring 2 813, and passes through the notch 814 to limit the extrusion plate 802, so that it is stored in the inside of the mounting groove 7, thereby avoiding repeated squeezing of the airbag 2 801, achieving the effect of closing the ventilation function of the breathable component 8, and preventing the air flow from causing discomfort to the soles of the patients' feet in cold weather.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
