Description

{APPARATUS FOR ANKLE STABILIZATION ORTHOSIS}

The present disclosure relates to an assistive device for ankle fixation.

In general, splints and casts are devices used to securely wrap and secure a part or all of a body part to limit its mobility and stabilize it when an emergency situation occurs, such as a trauma to the body, fracture, dislocation or sprain.

A cast is a structure that wraps a plaster-covered bandage around the affected area to fix it in place. It has excellent joint fixation, but it is not easy to put on and take off, and it is difficult to move the joint area while wearing it.

In particular, in the case of the ankle, which is the joint connecting the foot and the leg, if it is completely fixed with a cast, smooth walking becomes impossible, causing many difficulties for the user in real life. Therefore, it is difficult to use a cast on the ankle, which is a joint, and a fixation brace is used.

Recently, a plastic splint has been developed that allows the user to wear it like a shoe and allows joint movement. This is being used not only to treat patients with ankle injuries, but also as a walking assistance device for people with disabilities who have difficulty walking due to ankle disorders caused by diseases such as polio.

Korean Patent Publication No. 2009-0065734 (Title of invention: Ankle fixation brace, Publication date: 2009.06.23.) discloses a device that is worn on the ankle to fix the ankle while minimizing inconvenience in daily life.

Korean Patent No. 10-2456721 (Title of the invention: Customized ankle fixation brace, Registration date: October 16, 2022) discloses a device that stabilizes and fixes the wearer's ankle while allowing rotation of the ankle joint.

However, the above conventional technologies consist only of a plastic brace that forms a frame, and the brace is simply worn on the leg with a fixing band, etc. Therefore, the foot and leg, including the ankle, were not sufficiently wrapped and fixed together. In addition, since the shape was already set, it was difficult to stably fix the ankle according to the condition or affected area of various patients.

Moreover, as swelling of the ankles and the like subside over time, the size of the foot and leg, including the ankles, decreases and the appearance changes. In the past, it was difficult to change the appearance of the brace, so it was difficult to wrap and fix the entire foot and leg, including the ankle, to match the shape of the affected area that changes over time.

In addition, there is the disadvantage of inconvenience because the brace made of rigid material must be worn continuously even at night when walking is not necessary, such as when the ankle has somewhat recovered or while sleeping.

The objective of this project is to provide an ankle fixation assistive device that is easy to wear and can sufficiently wrap and fix the entire foot and leg, including the ankle.

The purpose of this project is to provide an ankle fixation assistive device that can be modified to fit the affected area regardless of the size or shape of the foot or ankle and stably wrap and fix the ankle.

The objective of this project is to provide an ankle fixation brace that can effectively wrap and secure the ankle, foot, and leg to a gradually changing area as swelling subsides over time.

The purpose of this project is to provide an ankle fixation assistive device having a double structure with a rigid inner core and a flexible outer shell, which enables fixation of the ankle using only the outer shell without using the inner core depending on the condition of the affected area.

The device of the present embodiment may include an upper body that is worn on and supported by a user's leg, a lower body that is rotatably connected to a lower portion of the upper body via a hinge axis and extends from the upper body to the user's ankle and supports the user's foot, an inner core made of a rigid material that fixes the user's ankle, and an outer shell that is installed to surround the entire inner core from the outside of the inner core and is made of a flexible material having its own elasticity to pressurize and fix the inner core to the user's body, and is detachably installed on the inner core and can be separated from the inner core to fix the user's ankle by itself.

The upper body may include an upper material that forms the upper part and wraps around the front and sides of the legs, side parts that are integrally formed at the lower ends on both sides of the upper material and come into contact with both sides of the user's legs and extend to the ankles, the rear of the upper body may be open to form a rear opening portion so that the legs can be inserted, and the front between the side parts may be structured to form a front cut portion.

The above-mentioned side may further include a cushion member installed on the lower inner surface and covering the hinge axis to prevent contact between the hinge axis and the body.

The lower body may include a bottom portion that supports the sole of the user's foot, a side support portion that extends upward from both side ends of the bottom portion and is connected to the lower side of the upper body via a hinge axis, and a rear cut portion that is cut inward from the rear end of the bottom portion to prevent contact with the user's heel.

The above outer shell may include a lower sheet part that is installed to wrap around the lower body in a cylindrical shape with open front and rear ends so that a user's foot can be inserted, and that compresses the user's instep to secure it to the lower body, an upper sheet part that is formed integrally with the lower sheet part and extends upward and has a rear end that is open so that a leg can be inserted, and that wraps around the front and side of the upper body, and a fixing means that is formed at both ends of the upper sheet part and elastically pressurizes and secures the outer shell to the inner core.

The above fixing means includes at least one first fixing part formed at one end of both ends of the upper sheet portion of the outer skin and extending outward, a Velcro installed at the end of the first fixing part and attached to the surface of the outer skin, at least one second fixing part formed at the other end and extending outward, and a Velcro installed at the end of the second fixing part and attached to the surface of the outer skin, and the first fixing part and the second fixing part may be structured to wrap the user's legs in opposite directions and attach and fix to the outer skin via the Velcro.

It may be a structure in which the outer shell is attached and detached to the inner core by using the Velcro, further including at least one Velcro installed in a corresponding position between the outer surface of the inner core and the inner surface of the outer shell to form a pair.

According to this embodiment, the inner core that fixes the ankle can be completely wrapped and fixed by the outer skin, so that it goes beyond simply wearing the inner core on the leg and can be effectively fixed by wrapping the inner core around the ankle as well as the entire foot and leg. Accordingly, movement of the inner core is prevented and the fixing force is increased, so that the affected area can be fixed more stably.

By applying heat to the inner core made of a plastic material, its shape can be appropriately changed to suit the condition of the affected area, and the outer shell can stably fix the auxiliary device to the affected area by compressing the inner core with its own elasticity. In addition, by wearing the inner core and outer shell, the auxiliary device can be customized to suit the shape of the affected area, so that even non-experts can use it easily.

By simply tightening the outer skin according to the changing condition of the affected area, the inner core material can be deformed to fit the affected area, thereby stably fixing the affected area according to the size or condition of the affected area without having to replace the inner core material.

Since the outer shell is structured to be detachable from the inner core, the inner core can be removed as needed and the entire affected area, including the ankle, leg, and foot, can be fixed using only the outer shell. Accordingly, various usage methods can be provided depending on the condition of the affected area or environmental conditions, and it can be used more comfortably.

For convenience of explanation below, the x-axis direction in Fig. 1 is referred to as the front-backward or forward-backward direction, and the front of the device along the x-axis direction is referred to as the front or front, and the back is referred to as the back or rear. In addition, the z-axis direction is referred to as the left-right or lateral direction, and the left and right sides of the device along the z-axis direction are referred to as the side or side. In addition, the y-axis direction is referred to as the up-down direction, and the upper side along the y-axis direction is referred to as the upper side or top, and the lower side is referred to as the lower side or bottom.

The auxiliary device (100) of the present embodiment is installed on the user's foot and calf (hereinafter referred to as "leg"), including the user's ankle, to fix the ankle area. The user's ankle area may refer to the area where the ankle joint connecting the foot and leg is located.

As illustrated, the auxiliary device (100) of the present embodiment may include an inner core (200) forming a skeleton, and an outer shell (300) that wraps the inner core (200) and secures it to the user's body.

The inner core (200) is made of a rigid structure to support the affected area and can limit the movement of the affected area. The inner core (200) is centered on the patient's ankle and extends to the foot and leg to stably support the patient's ankle area.

The inner core (200) may be made of a hard synthetic resin material. For example, the inner core (200) may be made of a thermoplastic resin that freely changes shape when heated and hardens and maintains its shape when cooled. The inner core (200) may be made of a thermoplastic material, and the structure or components may be modified in various ways. Accordingly, the inner core (200) made of a thermoplastic resin is heat-processed and worn on the user's foot and elastically pressed by the outer shell (300) described below, so that it can be custom-molded into an optimal shape corresponding to the affected area.

That is, when the plastically processed inner core (200) is worn on the foot and the outer shell (300) is worn on the outside of the inner core (200), the inner core (200) is elastically pressed by the outer shell (300) and is molded to fit the shape of the affected area. Accordingly, the affected area can be supported more stably, and even non-experts can easily mold the assistive device of the present embodiment to fit the affected area and use it conveniently anywhere.

The inner core (200) prevents twisting of the ankle and allows the ankle joint to move freely. To this end, the inner core (200) of the present embodiment has an upper body (210) that is worn on the user's leg and supported, and a lower body (230) that is rotatably connected to the lower part of the upper body (210) that extends from the upper body (210) to the user's ankle via a hinge axis (220) and supports the user's foot.

The upper body (210) and the lower body (230) are rotatably connected to each other about the hinge axis (220). Accordingly, the legs and feet can move the ankle joint about the hinge axis (220) while being fixed by the upper body (210) and the lower body (230), while preventing the ankle from twisting, thereby protecting the ankle.

The upper body (210) may include an upper member (211) and a side member (212) formed integrally with the upper member (211). The upper member (211) forms the upper end of the upper body (210) and is structured to surround the front and side of the leg.

Side parts (212) are provided on both sides of the upper part (211) along the lateral direction. Each side part (212) is integrally formed at the lower end of the upper part (211) and extends along the lower end to approximately the ankle. Each side part (212) contacts both sides of the user's legs and the lower end covers and wraps the ankle area.

The upper part (211) has an open rear structure, and the two side parts (212) formed on both sides of the upper part (211) are also separated from each other at the rear. Accordingly, the rear of the upper body (210) is completely open along the vertical direction to form a rear open part (213). Accordingly, the user's legs and ankles can be easily fitted and connected to the upper body (210) through the rear open part (213) of the completely open upper body (210).

Additionally, the upper body (210) may be opened at the front between the sides (212) to form a shear cut portion (214).

In this way, the upper body (210) is opened at the rear by the rear opening (213) and at the front by the front cutting (214) at the lower part of the upper material (211), with only the side (212) extending downward from the side. Therefore, it can be stably combined with the legs of various users regardless of the shape or size of the legs.

In this embodiment, a cushion member (215) may be further installed on the lower inner surface of the side (212). The cushion member (215) may be made of, for example, an elastic material pad such as rubber or urethane. Accordingly, the cushion member (215) covers the hinge axis (220) installed on the lower surface of the side (212) to prevent the hard hinge axis (220) from directly contacting the ankle. Accordingly, even if the device (100) of this embodiment is worn for a long time, the cushion member (215) can cushion the impact, thereby minimizing the skin on the ankle from being cut by the protruding hinge axis (220).

The lower body (230) may include a bottom portion (231) that supports the sole of the user's foot, a side support portion (232) that extends upward from both side ends of the bottom portion (231) and is connected to the lower end of the side portion (212) of the upper body (210) via a hinge axis (220), and a rear cut portion (233) that is cut inward from the rear end of the bottom portion (231) to prevent contact with the user's heel.

The lateral support parts (232) formed on both sides of the lower body (230) are rotatably connected to the lower end of the side part (212), respectively. Accordingly, the ankle joint can be rotated while the foot is fixed to the lower body (230).

The lower body (230) has an open structure on the front, top, and back, except for the bottom part (231) that comes into contact with the sole of the foot and the two side support parts (232).

The front of the lower body (230) is connected to the front cut portion (214) of the upper body (210) to form an open structure, and the rear of the lower body (230) is also connected to the rear open portion (213) of the upper body (210) to form an open structure. Accordingly, the user's foot can be easily inserted and connected through the open rear portion of the lower body (230).

The length of the bottom part (231) along the forward-backward direction is formed to be sufficiently smaller than the foot length.

Accordingly, as illustrated in FIG. 4, when the user's foot is completely inserted into the lower body (230), the front end of the bottom part (231) is positioned under the user's sole and does not protrude forward of the foot. Accordingly, the lower body (230) can be stably connected to the leg regardless of the size or shape of the foot. In addition, since the bottom part (231) does not protrude forward of the toes, interference between the bottom part (231) and the shoe is prevented even when the user wears shoes, making it easy to put on the shoes.

In this embodiment, a rear cut portion (233) is formed at the rear end of the bottom portion (231). The rear cut portion (233) is a portion that is cut inwardly from the rear end of the bottom portion (231) and removed, and can prevent the bottom surface of the user's heel from contacting the bottom portion (231). Accordingly, the lower body (230) can be worn on the foot regardless of the user's foot size or heel shape, and the heel can be prevented from contacting the hard material of the bottom portion (231) and being cut or impacted.

In this way, the lower body (230) supports the foot by making minimal contact only with the center of the sole of the user's foot through the bottom portion (231), so that it can be stably attached to the feet of various users regardless of the size or shape of the feet.

The inner core (200) of the above structure is elastically pressed by the outer shell (300) to stably support the affected area including the user's feet, legs, and ankles.

The outer shell (300) of this embodiment is structured to wrap the entire inner core (200) from the outside of the inner core (200). The outer shell (300) is structured to be detachably installed on the inner core (200), and can be separated from the inner core (200) and secure the user's ankle on its own.

Accordingly, the user's ankle can be fixed using only the outer shell (300) with the inner core (200) removed. Accordingly, the outer shell (300) and the inner core (200) can be used together or only the outer shell (300) can be used as needed, so that various usage methods can be provided depending on the condition of the affected area or environmental conditions.

The outer shell (300) is made of a flexible material with its own elasticity, and can wrap and compress the inner core (200) to pressurize and fix the inner core (200) to the user's affected area.

The outer shell (300) may be made of an elastic material, for example, a synthetic fiber material. The material of the outer shell (300) may be modified in various ways. The outer shell (300) may be made of a structure in which at least two layers of different materials are laminated. The inner surface of the outer shell (300) may be made of various types of materials as long as they are not harmful to the body skin. The outer surface of the outer shell (300) may be made of a cloth material to which Velcro (333) may be attached. Accordingly, the Velcro (333) provided on the fixing means (330) may be attached anywhere on the outer surface of the outer shell (300). In this way, since the outer shell (300) is made of a material that can be attached to Velcro as a whole, the fixing means (330) may be moved to fit the user's affected area or body shape, and the outer shell (300) may be attached anywhere on the outer shell (300) for use.

In this embodiment, at least one Velcro (250) that is attached to each other as a pair may be further installed at a corresponding position between the outer surface of the inner core (200) and the inner surface of the outer skin (300). Velcro is also called a fastener and has a structure that is attached and detached from each other through a hook and loop formed on both sheet surfaces. Since it is already known in the art, a detailed description is omitted.

The paired Velcro (250) can be installed on the front and side of the upper material (211) of the upper body (210), the bottom surface (231) of the lower body (230), and the inner surface of the corresponding outer skin (300), respectively.

Accordingly, the outer shell (300) can be firmly attached and fixed by wrapping the inner core (200) according to the shape of the inner core (200) by the Velcro (250). In addition, the inner core (200) and the outer shell (300) can be separated by separating the Velcro (350) from each other when necessary.

The outer shell (300) may be formed in a shape and size that roughly correspond to the shape and size of the inner core (200) and may be structured to be installed while wrapping around the inner core (200).

To this end, the outer shell (300) of the present embodiment may include a lower sheet part (310) that wraps around the lower body (230), an upper sheet part (320) that wraps around the upper body (210), and a fixing means (330) formed on the upper sheet part (320).

The lower seat part (310) has a cylindrical shape with open front and rear ends and is installed to completely wrap around the lower body (230). The size of the lower seat part (310) is sufficient if it can wrap around the lower body (230).

Accordingly, the lower sheet part (310) wraps around the bottom part (231) and the support part (232) of the lower body (230), as well as the open upper surface. Accordingly, as shown in Fig. 4, the instep of the user's foot exposed through the open upper surface of the lower body (230) is wrapped and compressed by the lower sheet part (310), thereby being firmly fixed to the lower body (230).

The upper seat part (320) is formed integrally with the lower seat part (310) and is structured to extend upwards to completely wrap around the front and side (212) of the upper body (210). The upper seat part (320) is formed to extend so as to naturally bend upwards from the upper and rear ends of the lower seat part (310).

As with the upper body (210), the rear of the upper seat portion (320) is formed completely open so that a leg can be inserted. Accordingly, even when the inner core (200) is installed by wrapping it with an outer shell (300), the device (100) can be easily mounted on a leg through the open rear.

The upper seat part (320) is installed to completely wrap around the front and side of the upper body (210). Accordingly, the upper body (210) can be firmly fixed to the user's legs by applying pressure to the entire upper body (210).

The fixing means (330) are formed at both ends of the upper sheet portion (320) to elastically pressurize and fix the outer skin (300) to the inner core material (200). The upper sheet portion (320) is pulled and fixed as a whole by the fixing means (330), thereby preventing separation from the inner core material (200) and fixing the inner core material (200) to the user's body by pressing.

The fixing means (330) of the present embodiment includes at least one first fixing part (331) formed at one end of the upper sheet portion (320) of the outer skin (300) and extending outward, a Velcro (333) installed at the end of the first fixing part (331) and attached to the surface of the outer skin (300), at least one second fixing part (332) formed at the other end and extending outward, and a Velcro (333) installed at the end of the second fixing part (332) and attached to the surface of the outer skin (300). The first fixing part (331) and the second fixing part (332) may be structured to wrap around the user's legs in opposite directions and attach and fix them to the outer skin (300) via the Velcro (333).

The first fixed part (331) and the second fixed part (332) are made of the same material as the outer shell (300) and can be formed to extend outward from the rear end of the upper sheet part (320) of the outer shell (300).

The first fixing part (331) and the second fixing part (332) can be formed spaced apart from each other at both ends of the upper sheet part (320) along the vertical direction. The first fixing part (331) is positioned relatively upwardly so as to fix the upper end of the inner core (200) to the calf part of the user's leg, and the second fixing part (332) is positioned relatively downwardly so as to pressurize and fix the inner core (200) to the ankle part of the user's leg.

The first fixing part (331) and the second fixing part (332) may be formed at opposite positions to each other and may have a structure that wraps the user's body in opposite directions to fix it. Accordingly, the first fixing part (331) and the second fixing part (332) apply force in opposite directions to each other, thereby preventing the outer skin (300) from rotating to one side during the fixing process and fixing it in a balanced manner.

As illustrated in FIG. 3, a cover part (334) may be further provided on the opposite end of the upper sheet part (320) so as to face the first fixing part (331). The cover part (334) may be integrally formed in the outer shell (300) and may be attached and installed as a protruding portion to which the first fixing part (331) is attached. Accordingly, the first fixing part (331) may be attached and fixed to the outside of the cover part (334) while the user's leg is wrapped around the cover part (334). Accordingly, the cover part (334) and the first fixing part (331) doubly wrap around the leg, thereby fixing the leg more stably, and even a user with thick legs can attach the first fixing part (331) using the cover part (334).

A Velcro (333) for connection with the outer shell (300) may be fixedly installed at each end of the first fixing member (331) or the second fixing member (332). As mentioned above, the outer shell (300) of the present embodiment is made of a material to which the Velcro (333) can be attached, and by pulling the first fixing member (331) and the second fixing member (332) to attach the Velcro (333) installed at the end to the outer shell (300), the fixing means (330) can be simply fixed to the outer shell (300).

The first fixing part (331) or the second fixing part (332) can be formed to a sufficient length so that the Velcro (333) installed at the tip can be attached to the outer skin (300) while wrapping the inner core (200).

In addition, as mentioned, the first fixing part (331) and the second fixing part (332) are structured to pull in opposite directions, so that the forces pulling the first fixing part (331) and the second fixing part (332) cancel each other out, and thus no rotational moment occurs at all. Accordingly, the outer shell (300) can be fixed while accurately compressing the inner core (200) without being twisted.

As illustrated in FIG. 4, when the first fixing part (331) and the second fixing part (332) are pulled and fixed to the outer skin (300), the inner core (200) is compressed by the outer skin (300) and fixed to the affected area. That is, the upper sheet part (320) of the outer skin (300) is firmly fixed to the calf part of the user's leg by the first fixing part (331). The upper sheet part (320) of the outer skin (300) is pressurized and fixed to the ankle part of the user's leg by the second fixing part (332). In addition, as the first fixing part (331) and the second fixing part (332) are pulled and attached to the outer skin (300), the lower sheet part (310) of the outer skin (300) is also pulled and compresses the inner core (200) and directly compresses the user's instep to firmly fix it.

In this way, the outer skin (300) is pulled by the fixing means (330) to elastically compress the inner core (200), thereby firmly fixing the user's legs, ankles, and feet.

Accordingly, the device (100) goes beyond simply wearing the inner core (200) on the leg, and the outer shell (300) effectively compresses and fixes the entire foot and leg, as well as the ankle. Accordingly, movement of the inner core (200) is prevented and fixation strength is increased, so that the affected area can be fixed more stably.

Meanwhile, Fig. 5 illustrates a structure for pressurizing and fixing a wound using only the outer shell (300) of the present embodiment.

As shown in Fig. 5, the outer skin (300) can wrap and fix the entire affected area, including the ankle, leg, and foot, with the inner core (200) separated and removed.

The outer shell (300) is configured to be detachable from the inner core (200), so that the inner core (200) can be removed as needed and only the outer shell (300) can be used to fix the entire affected area, including the ankle, leg, and foot.

The outer shell (300) can be worn on the leg by inserting the foot and leg into the outer shell (300) through the open back of the outer shell (300). Then, by pulling the first fixing part (331) and the second fixing part (332) installed on the upper sheet while the lower sheet is fitted on the horse and attaching them to the outer shell (300) via Velcro (333), the ankle, the foot, and the entire leg are wrapped and fixed by the outer shell (300).

Accordingly, even when the inner core (200) is separated and removed, the entire affected area can be wrapped and fixed with only the outer shell (300), and the affected area can be wrapped and protected with a softer outer shell (300) without using a hard, rigid inner core (200).

Therefore, when the affected area has recovered to some extent, the affected area can be fixed with only the soft outer skin (300) to enable more comfortable use.

In this way, the device (100) can protect and treat the affected area by fixing it in various ways, such as by using both the inner core (200) and the outer shell (300) or by using only the outer shell (300), depending on the condition of the affected area or environmental conditions.

While exemplary embodiments of the present invention have been illustrated and described above, it will be apparent to those skilled in the art that various modifications and other embodiments may be made thereto. It is intended that all such modifications and other embodiments be considered and encompassed by the appended claims and do not depart from the true spirit and scope of the present invention.
