Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the lower limb fracture protection device is schematically shown to comprise a force discharge shoe 1 and an inner protection structure 2 arranged inside the force discharge shoe 1.

In the embodiment of the present application, the inner protective structure 2 includes a lower limb fixing structure 21, a pressure adjusting structure 22, an ankle stress ring 23, a leg stress ring 24, and a positioning block 25.

Wherein the lower limb fixing structure 21 is provided at the ankle or the lower part of the ankle.

The pressure adjusting structure 22 is disposed on the lower limb fixing structure 21 and can adjust the stress of the affected limb.

An ankle force ring 23 is connected to the lower limb securing structure 21.

The leg stress ring 24 is sleeved on the affected limb, and the leg stress ring 24 and the ankle stress ring 23 are respectively positioned at the upper side and the lower side of the fracture line. Therefore, the fracture line part of the affected limb can be well protected.

A positioning block 25 is arranged on the leg force bearing ring 24, a through hole 11 is formed on the force unloading boot 1, wherein, when the force of the ankle force bearing ring 23 reaches a preset pressure value, the positioning block 25 moves downwards and can be inserted into the through hole 11. In particular, for patients with fractures of feet or legs, the patients need to exercise continuously to accelerate rehabilitation, the differentiation of osteoblasts can be promoted by small to medium load, the proportion of osteoblasts can be increased by larger stress to promote fracture healing, and therefore, different pressures need to be applied to the patients in different fracture rehabilitation stages to effectively improve the functions of the affected limbs. However, the patient cannot accurately grasp the magnitude of the load force, so that during the weight training, the risk of fracture displacement and internal fixation failure due to too large pressure exists, and the training effect cannot be achieved due to too small load.

However, the patient can effectively avoid the risk of fracture displacement and internal fixation failure due to too large pressure in weight training because the patient cannot accurately grasp the magnitude of the load force by using the lower limb fracture protection device of the present application, and specifically, the ankle fixing ring 23 and the leg force receiving ring 24 are first worn on the ankle and the leg of the affected limb, respectively, and the ankle fixing ring 23 and the leg force receiving ring 24 are fixed at both ends of the fracture line, respectively.

Then, the ankle fixing ring 23 is firmly connected to the ankle of the affected limb by means of the binding band, and the leg force receiving ring 24 is firmly connected to the leg of the affected limb by means of another binding band.

The pressure that this pressure regulation structure 22 can bear is adjusted the size for this pressure regulation structure 22 reaches suitable pretightning force, then, wears to unload power boots 1 again, wears to accomplish. Therefore, the lower limb fracture protection device is easy to wear, and the maximum safe load can be adjusted by a user according to the requirement. When the stress of the pressure adjusting structure 22 is smaller than the preset pressure value, it indicates that the fracture leg of the patient does not reach the safe load after being stepped on, and at the moment, the stress of the fracture line part is not too large, so that the risks of fracture displacement and internal fixation failure of the fracture part can be effectively avoided.

If the atress of pressure regulation structure 22 equals after presetting the pressure value, it indicates that patient's fracture leg has reached safe heavy burden after stepping on, at this moment, locating piece 25 can insert in through-hole 11, promptly, locating piece 25 can overlap joint on this power of unloading boots 1, through the rigid contact between the two, accomplish and unload the power, promptly, the unnecessary atress after stepping on the fracture leg can be transmitted for locating piece 25 through this power of unloading boots 1, and then, transmit for shank atress ring 24, like this, just can not make the atress at fracture position too big, thereby can avoid fracture position to take place fracture aversion and internal fixation failure's risk effectively.

In addition, when the fracture leg is lifted, the force-unloading boot 1 is taken up, and the fracture line only bears the gravity of the force-unloading boot 1, which is far less than the safe load, so that the fracture part is not stressed too much.

In addition, after the lower limbs fracture protection device of this application was worn to the fracture patient, alright in order to accomplish daily life with a burden, need not with the help of the walking stick, make things convenient for patient's life, and do benefit to the patient and take exercise normal walking, simultaneously, can also effectively guarantee that the biggest atress of suffering from the limb can not exceed and predetermine the pressure value for suffer from the biggest atress of limb can be located safe within range.

The "preset pressure value" refers to a maximum pressure that the fractured leg can bear after being stepped on, and if the maximum pressure is exceeded, the fracture line is damaged, and the fracture part is displaced and the internal fixation fails.

In a preferred embodiment of the present application, as shown in fig. 1 and 2, the lower limb fracture protection device further comprises a sole plate 3 disposed on the bottom wall of the force discharge boot 1. It should be noted that the sole plate 3 may be made of a hard material, preferably plastic.

It will be appreciated by those skilled in the art that the sole plate 3 is shaped to conform to the shape of the sole plate of a normal shoe to accommodate the foot of a patient.

In another preferred embodiment of the present application, the lower limb fixing structures 21 are two and respectively disposed at left and right sides of the ankle, and each of the lower limb fixing structures 21 includes a side fixing plate 211 connected to the sole plate 3.

The side fixing plate 211 should have a certain structural strength to prevent the side fixing plate 211 from being damaged during walking with the affected limb.

It should also be noted that the side fixing plates 211 may be integrally formed with the respective sides of the sole plate 3.

In another preferred embodiment of the present application, as shown in fig. 1 and 2, the pressure adjustment structure comprises a lower adjustment column 221 arranged at a respective side of the bottom wall of the force shoe 1, wherein the lower adjustment column 221 is arranged at the outer side of the side fixing plate 211 at the respective side.

In another preferred embodiment, the pressure adjusting structure 22 further includes an upper adjusting post 222 disposed up and down opposite to the lower adjusting post 221 and a displacement adjusting member 223 disposed between the lower adjusting post 221 and the upper adjusting post 222.

It should be noted that the displacement adjustment member 223 has a certain capability of elastic deformation in the longitudinal direction, that is, by moving the upper adjustment column 222 in the direction of the lower adjustment column 221, the longitudinal deformation amount of the displacement adjustment member 223 can be changed, and at the same time, the displacement adjustment member 223 can bear a certain elastic pressure when elastic deformation occurs.

Similarly, when the upper adjustment post 222 moves away from the lower adjustment post 221, the displacement adjustment member 223 gradually returns to its original state (reset state).

As shown in fig. 1, in order to further optimize the displacement adjustment member 223 in the above technical solution, in addition to the above technical solution, the displacement adjustment member 223 includes a positioning rod 223a and an elastic member 223b sleeved on the periphery of the positioning rod 223 a. It should be noted that the positioning rod 223a mainly plays a guiding role, that is, when the upper adjusting column 222 moves in the direction of the lower adjusting column 221, the elastic member 223b is inevitably compressed, and at this time, the elastic member 223b is inevitably elastically deformed, that is, the distance of the elastic member 223b in the longitudinal direction is shortened, and at the same time, the middle portion of the elastic member 223b is easily protruded outward, so that the elastic member 223b is sleeved on the positioning rod 223a, thereby effectively avoiding the above situation.

The upper adjustment column 222 and the lower adjustment column 221 are both hollow, the upper end of the positioning rod 223a is disposed in the upper adjustment column 222, and the lower end of the positioning rod 223a is disposed in the lower adjustment column 221. Thus, the upper adjustment post 222 can be moved in the direction of the lower adjustment post 221 to compress the elastic member 223b, so that the fractured leg can bear appropriate pressure after being stepped on.

In addition, the lower adjustment column 221 has a hollow structure inside, so that the positioning rod 223a can be fixed, and the positioning rod 223a can be prevented from being inclined or being positioned loosely.

The upper adjusting column 222 is configured to be hollow, so that a sufficient space is provided for the upper adjusting column 222 to move in the direction of the lower adjusting column 221, and the situation that the upper adjusting column 222 is blocked when the upper adjusting column 222 is moved downwards due to the fact that the top end of the inner part of the upper adjusting column 222 is already in contact with the upper end of the positioning rod 223a when the elastic component 223b is not yet compressed to the maximum extent is avoided.

It should be noted that the elastic member 223b may be a spring, an elastic tube, or other members having an elastic function.

As shown in fig. 1 and 2, in a preferred embodiment of the present application, the pressure adjusting structure 22 further includes an adjusting screw 224 and a connecting block 225 disposed on the side fixing plate 211. The connection block 225 may be integrally manufactured with the side fixing plate 211 or the connection block 225 may be fixed to the side fixing plate 211 by welding.

A connecting plate 226 is mounted on the upper end surface of the upper adjusting column 222, a first through hole (not shown) is formed in the connecting plate 226, and a second through hole (not shown) is formed in the connecting block 225, and the first through hole and the second through hole are arranged opposite to each other in the vertical direction and form a longitudinal adjusting hole together. It should be noted that the first through hole and the second through hole have the same diameter to form the longitudinal adjusting hole together.

The adjusting end of the adjusting screw 224 passes through the longitudinal adjusting hole, wherein the adjusting screw 224 is rotated to drive the connecting plate 226 to move up and down, and the upper adjusting column 222 is driven to move closer to and away from the lower adjusting column 221 by the up and down movement of the connecting plate 226. Specifically, the longitudinal adjusting hole is configured as a threaded hole, and by rotating the adjusting screw 224 (clockwise rotation or counterclockwise rotation), the longitudinal position of the adjusting screw 224 in the threaded hole can be changed to drive the connecting plate 226 to move in the longitudinal direction, and further, by adjusting the position of the connecting plate 226 in the longitudinal direction, the upper adjusting column 222 can move toward and away from the lower adjusting column 221, so that the fractured leg can bear corresponding pressure after being stepped on.

As shown in fig. 1 and 2, in another preferred embodiment of the present application, each of the pressure adjusting structures 22 further includes a ratchet (not shown) respectively disposed on the side fixing plates 211 of the corresponding sides and an elastic member (not shown) disposed on an upper end surface of the lower adjusting column 221, wherein the elastic member is compressed by driving the rotation of the ratchet. Specifically, by disposing the ratchet on the side fixing plate 211, that is, mounting the rotating shaft on the side fixing plate 211, sleeving the ratchet on the rotating shaft, and fixedly connecting the rotating shaft and the ratchet in the circumferential direction, the ratchet is driven to rotate in the circumferential direction by driving the rotating shaft, and by the rotation of the ratchet, the elastic member can be compressed to adjust the longitudinal force applied by the displacement adjusting member 223.

If the current elastic component reaches the maximum deformation amount and the current stress of the elastic component is equal to the preset pressure value, the stress after the fracture leg is stepped on is equal to the preset pressure value, namely, the safe load is reached, at the moment, the positioning block 25 is inserted into the through hole 11 in the force unloading boot 1, further, the redundant stress is transmitted to the positioning block 25 through the force unloading boot 1 and then transmitted to the leg stress ring 24, so that the purpose of dispersing the redundant stress at the fracture line position is achieved, and the excessive stress at the fracture line position is avoided.

In a preferred embodiment of the present application, as shown in fig. 1, the lower limb fracture protection device further comprises wear prevention members 4 disposed inside the ankle force ring 23 and the leg force ring 24, respectively. It should be noted that, since the ankle force-bearing ring 23 and the leg force-bearing ring 24 both bear a certain force when the patient walks or raises the leg, in order to avoid the ankle force-bearing ring 23 and the leg force-bearing ring 24 from being damaged, the ankle force-bearing ring 23 and the leg force-bearing ring 24 should be made of hard materials.

It should be noted that the arrangement of the wear-proof member 4 can prevent the leg force-bearing ring 24 and the ankle force-bearing ring 23 from being displaced relative to the affected limb.

In addition, since the ankle force-receiving ring 23 and the leg force-receiving ring 24 are respectively in contact with the ankle and the leg of the patient, in order to prevent the ankle and the leg of the patient from being worn or scratched by the ankle force-receiving ring 23 and the leg force-receiving ring 24, the wear-preventing member 4 is disposed on the inner side of the ankle force-receiving ring 23 and the leg force-receiving ring 24, so that the wear-preventing condition can be well prevented.

In a particular embodiment, the wear member 4 is preferably a bladder, rubber pad, silicone strip, or the like. It will be readily appreciated that the wear part 4 is not limited to that exemplified in the embodiment, but can be flexibly adjusted to the actual requirements. That is, the wear-proof member 4 only needs to be made of a flexible material, and the specific shape of the wear-proof member 4 is not limited.

In a preferred embodiment, as shown in fig. 1, the lower limb fracture protection device further comprises a bladder 5 disposed on the sole plate 3 and capable of being worn on the foot and leg of the affected limb. This inner bag 5 is made by flexible material, like this, on the one hand, can ensure that inner bag 5 wears behind the foot and the shank of suffering from the limb, can be attached with the foot and the shank of suffering from the limb is intact, and on the other hand, can also avoid taking place the condition of fish tail to the shank or the foot of suffering from the limb.

Wherein, a flexible insole 6 is arranged between the sole plate 3 and the inner container 5. Specifically, the flexible insole 6 can be firmly fixed on the sole plate 3 by means of gluing or threading, so that the situation that the hardness of the sole plate 3 is strong, which causes discomfort to the foot of a patient during walking, is reduced.

In summary, for patients with fractures of feet or legs, the patients need to exercise continuously to accelerate rehabilitation, the differentiation of osteoblasts can be promoted by small to medium load, the proportion of osteoblasts can be increased by larger stress to promote fracture healing, and therefore, different pressures need to be applied to the patients in different fracture rehabilitation stages to effectively improve the functions of the affected limbs. However, the patient cannot accurately grasp the magnitude of the load force, so that during the weight training, the risk of fracture displacement and internal fixation failure due to too large pressure exists, and the training effect cannot be achieved due to too small load.

However, the patient can effectively avoid the risk of fracture displacement and internal fixation failure due to too large pressure in weight training because the patient cannot accurately grasp the magnitude of the load force by using the lower limb fracture protection device of the present application, and specifically, the ankle fixing ring 23 and the leg force receiving ring 24 are first worn on the ankle and the leg of the affected limb, respectively, and the ankle fixing ring 23 and the leg force receiving ring 24 are fixed at both ends of the fracture line, respectively.

Then, the ankle fixing ring 23 is firmly connected to the ankle of the affected limb by means of the binding band, and the leg force receiving ring 24 is firmly connected to the leg of the affected limb by means of another binding band.

The pressure that this pressure regulation structure 22 can bear is adjusted the size for this pressure regulation structure 22 reaches suitable pretightning force, then, wears to unload power boots 1 again, wears to accomplish. Therefore, the lower limb fracture protection device is easy to wear, and the maximum safe load can be adjusted by a user according to the requirement. When the stress of the pressure adjusting structure 22 is smaller than the preset pressure value, it indicates that the fracture leg of the patient does not reach the safe load after being stepped on, and at the moment, the stress of the fracture line part is not too large, so that the risks of fracture displacement and internal fixation failure of the fracture part can be effectively avoided.

If the atress of pressure regulation structure 22 equals after presetting the pressure value, it indicates that patient's fracture leg has reached safe heavy burden after stepping on, at this moment, locating piece 25 can insert in through-hole 11, promptly, locating piece 25 can overlap joint on this power of unloading boots 1, through the rigid contact between the two, accomplish and unload the power, promptly, the unnecessary atress after stepping on the fracture leg can be transmitted for locating piece 25 through this power of unloading boots 1, and then, transmit for shank atress ring 24, like this, just can not make the atress at fracture position too big, thereby can avoid fracture position to take place fracture aversion and internal fixation failure's risk effectively.

In addition, when the fracture leg is lifted, the force-unloading boot 1 is taken up, and the fracture line only bears the gravity of the force-unloading boot 1, which is far less than the safe load, so that the fracture part is not stressed too much.

In addition, after the lower limbs fracture protection device of this application was worn to the fracture patient, alright in order to accomplish daily life with a burden, need not with the help of the walking stick, make things convenient for patient's life, and do benefit to the patient and take exercise normal walking, simultaneously, can also effectively guarantee that the biggest atress of suffering from the limb can not exceed and predetermine the pressure value for suffer from the biggest atress of limb can be located safe within range.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
