Description

Medical joint rehabilitation orthosis {Medical Rehabilitation Orthosis for Joint}

The present invention relates to a joint rehabilitation aid, and more particularly, to a medical joint rehabilitation aid capable of improving the efficiency of rehabilitation treatment by preventing excessive strain on a joint until the joint is fully recovered.

Patients who have to lie down for a long time due to surgery, because they cannot move for a long time, lose their muscles slowly and weaken their strength. For example, the joints and unit muscle strength necessary for walking are weakened and hardened. For example, most fracture patients cannot walk properly after dismantling a cast or fixation device because they are kept immobile in a cast or fixation device for a long period of time. In addition, even without surgery, gait muscle strength is weakened due to aging, and it is important for the elderly with weakened gait ability to increase unit muscle strength by themselves and maintain a state in which they can walk freely through joint motion.

On the other hand, weakening of the muscles or ligaments of the lower extremities can cause valgus or valgus. Hallux valgus or varus knee causes pain in the knee and various diseases related to the joint, and it is bound to give strain to the hip joint. In addition, internal rotation of the hip joint adversely affects the knee and ankle joints as well as the lumbar spine.

In order to solve various problems caused by the weakness of the lower limb muscles, various rehabilitation services including physical therapy are provided, and rehabilitation aids worn on the body are also used.

Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Basically, the joint rehabilitation aid of the present invention fixes and protects a joint (until it is completely restored). For example, it blocks unnecessary movement of joints after surgery to induce rapid recovery. These braces can be applied to all joints of the body, and, for example, as shown in FIG. 1 , they can also be used for assisting rehabilitation of the hip joint.

FIG. 1 is a view for explaining the basic configuration of a medical joint rehabilitation aid 20 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the medical joint rehabilitation aid shown in FIG. 1 . In addition, Figure 3 is a cross-sectional view along the line A-A of Figure 2, Figure 4 is a perspective view cut away of the tension control unit of Figure 1.

As shown, the medical joint rehabilitation aid 20 according to the present embodiment includes a first wearing fixing part 40, a second wearing fixing part 50, a manipulation unit 60, and a power transmission unit 80. do.

The first wearing fixing part 40 is installed on the hip 11 of the body 10, that is, on the waist, and the second wearing fixing part 50 is installed on the thigh 13. The size or shape of the first and second wear fixing parts 40 and 50 may vary as much as possible.

Also, the rehabilitation aid 20 can be applied to other joints. For example, it is possible to perform rehabilitation of the knee joint by fixing the first wear fixing part to the thigh and installing the second wearing fixing part to the lower leg.

The first wearing fixing part 40 includes a wearing band 41, a wearing holding part, and a first support panel 61. The wearing band 41 is a belt-like member having elasticity and wraps around the waist of the body 10 and presses it. The wear band 41 supports the upper end of the power transmission unit 80, and the structure of the wear band 41 can be changed as long as it can perform this function.

The wearing holding part maintains a state in which the wearing band 41 is wrapped around the waist, and includes a plurality of adhesive cloths 42 and 43. The adhesive cloths 42 and 43 are Velcro cloths, and when the wearable band 41 is wrapped around the waist, they face each other and are adhesively fixed. In addition to the adhesive cloth, other fixing means such as buttons or hooks may be applied.

The first support panel 61 is a plate-like member having a predetermined thickness fixed to the outer surface of the wearable band 41 and supports one end of the housing 63 and the variable strip 81 . The first support panel 61 can be made of synthetic resin.

The second wear fixing part 50 has the same configuration as the first wearing fixing part 40 . The second wearing fixing part 50 is fixed to the outer surface of the wearing band 51 for wrapping the thigh part 13, the wearing holding part for maintaining the state in which the wearing band is wound around the thigh part, and the wearing band 51 and provides support. A second support panel 55 is provided. The wearing holding part is a pair of adhesive cloths 52 and 53 that are bonded and fixed to each other. When the femur is wrapped with the unfolded wearing band 51, the adhesive cloths 52 and 53 automatically face each other. Like the first support panel 61, the second support panel 55 is a plate-like member having a certain thickness, and is made of synthetic resin.

The control unit 60 is mounted on the first support panel 61, and when the joint between the first and second wear fixing units 40 and 50 is distorted, it is manipulated by the user to output a tensile force. The reason for outputting the tensile force is to correct the distorted muscles. For example, as shown in FIG. 5 for various reasons, when one leg goes inward and the hip joint is distorted, a tensile force is output to pull the corresponding leg in the direction of the arrow k. The output tensile force is transmitted to the second wear fixture 50 via a power transmission unit 80 to be described later. In this description, the meaning of a joint being distorted encompasses a deformation of a joint from a normal state to an abnormal state.

As shown in detail in FIG. 4, the control unit 60 includes a housing 63, an introduction guide 64, a pull reel 65, a driving gear 67d, a torque transmission shaft 67e, and a control dial 67a. ), and a fixing pin 68.

The housing 63 is a hollow disk-shaped member providing an accommodation space 63a, and its bottom surface is tightly fixed to the outer surface of the first support panel 61. In addition, a plurality of locking holes 63e are formed on the upper surface of the housing 63. The locking hole 63e is a through hole equiangularly arranged around the torque transmission shaft 67e and receives the lower end of the fixing pin 68.

The introduction guider 64 is an iron piece fixed to the inside of the wire entrance 63c and guides the tension wire 71 pulled in the direction of arrow g toward the tension reel 65.

The tension reel 65 is rotatably installed in the accommodating space 63a of the housing and serves to wind the tension wire 71. A support shaft 65a is provided at the center of the tension reel 65 . The support shaft 65a supports the pull reel 65 rotatably. In particular, the pull reel 65 is provided with a gear portion 65c. The gear part 65c is a part that receives rotational torque input from the control dial 67a and meshes with the drive gear 67f.

The drive gear 67f is a gear that meshes with the gear portion 65c of the tension reel, and has a torque transmission shaft 67e at its center. The torque transmission shaft 67e passes through the upper plate 63b and is coupled with the control dial 67a outside the housing 63.

The operation dial 67a is a disk-shaped member handled by the user. The rotational force of the control dial 67a is transmitted to the gear unit 65c via the torque transmission shaft 67e and the driving gear 67f. For example, when the operation dial 67a is rotated in the direction of arrow m, the pulling reel 65 rotates in the direction of arrow n and pulls the tension wire 71 in the direction of arrow g.

In addition, a pin hole 67b is provided in the outer portion of the operation dial 67a. The pin hole 67b is a hole through which the fixing pin 68 passes. After positioning the pin hole 67b at a vertical upper part of an arbitrary locking hole 63e, when the fixing pin 68 is inserted into the pin hole 67b, the lower end of the fixing pin 68 is inserted into the locking hole 63e. Thus, rotation of the operation dial 67a is prevented. Reference numeral 67c denotes a holder. The holder (67c) is connected to the fixing pin (68) through the loss prevention strap (69). The fixing pin 68 is held by the holder 67c by the loss prevention strap 69 and there is no fear of loss.

On the other hand, the power transmission unit 80, in a state in which the first wear fixing portion 40 and the second wearing fixing portion 50 are connected, receives the tensile force provided from the operation unit and bends itself, and applies the bending force to the second It is transmitted to the wearing fixing part 50. The bending force transmitted to the second wear fixing part 50 is used as a force pulling the second wearing fixing part 50 in the direction of the arrow k. The force acting in the direction of the arrow k physically moves the joint in an abnormal state and returns it to a normal state.

The power transmission unit 80 includes a variable strip 81, a plurality of unit blocks 83, and a tensile wire 71.

The variable strip 81 is a flexible member extending in the longitudinal direction and having a predetermined width, and has side grooves 81a at both ends in the width direction. The side groove 81a is a gap for accommodating and supporting the separation prevention protrusion 83f of the unit block 83. The variable strip 81 can be made of silicone or rubber. Both ends of the variable strip 81 are fixed to the upper surfaces of the first support panel 61 and the second support panel 55, respectively.

The unit block 83 is a hexahedral member with a narrow top surface and a wide bottom surface, like a key on a computer keyboard. The bottom part of each other is in close contact.

The lower end of the unit block 83 is in close contact with each other, but is spread upward as a whole. The reason why it is formed so that it spreads upward is to prepare for when the legs need to be spread outward, as shown in FIG. 6 . If there is no space between the unit blocks 83, bending of the power transmission unit 80 in the direction of the arrow k is impossible.

Separation prevention protrusions 83f are formed on both sides of the lower end of the unit block 83 . The separation prevention protrusion 83f is a part fitted into the side groove 81a of the variable strip 81. The unit block 83 is not separated from the variable strip 81 as long as the separation preventing protrusion 83f is maintained in the side groove 81a.

As mentioned above, since the unit block 83 is a hexahedron whose area of the lower end is larger than that of the upper end (except for the anti-separation protrusion), it has inclined surfaces 83g on all sides. Among the inclined surfaces 83g, the angle θ between the opposite inclined surfaces 83g of adjacent unit blocks can be designed in various ways. The angle between the variable strips 81 in a state in which they are stretched in a straight line may range from 10 degrees to 30 degrees. The angle between them increases when the legs are pulled to one side and decreases when they are spread outward.

In addition, each unit block 83 is provided with a through hole 83a and a locking space 83d. The through hole 83a is a passage passing through in a direction parallel to the longitudinal direction of the variable strip 81, and can pass the tensile wire 71 therethrough. The tensile wire 71 passes through the through hole 83a of each unit block 83 arranged in a row, one end is caught and fixed in the locking space 83d of the end unit block 83, and the other end is fixed. It is wound on the tension reel (65).

The locking space 83d is a groove formed on the upper surface of the unit block 83, and is open upward through the ball inlet 83c. The locking space 83d accommodates and fixes the locking ball 71a of the tension wire 71 in a detachable manner.

The locking ball 71a is a part fixed to the end of the tension wire 71, and has a larger diameter than the diameter of the tension wire 71. When the locking ball 71a is inserted into the ball entrance 83c and then pulled in the direction of arrow f, it is caught in the locking space 83d and does not fall upward.

When the control dial 67a is rotated in the direction of the arrow m while the locking ball 71a is inserted into the locking space 73d (of the end unit block 83 in the direction of the second wearing fixture), the power transmission unit 80 is pulled in the direction of arrow f, and finally bent in the direction of arrow k. The reason such bending is possible is that the inclined surface 83g is formed on the unit block 83. Also, when rotating the control dial 67a, pressing the approximately central portion of the power transmission unit 80 in the direction of the arrow p starts bending more easily.

5 and 6 are views for explaining the operation of the rehabilitation aid 20 according to an embodiment of the present invention.

As shown, the first wearing fixing part 40 and the upper part of the hip 11 and the right thigh 13 of the patient whose right leg (left side in the drawing) is gathered inward (regardless of the patient's intention) 2 wearing fixing parts 50 are respectively mounted. The rehabilitation aid 20 spreads the right leg outward and applies force so that the patient can stand.

After the first and second wearing fixing parts 40 and 50 are installed, when the control dial 67a is rotated in the direction of arrow m, the tension wire 71 is stretched and the variable strip 81 is bent in the direction of arrow k. let it The reason why such bending is possible is that a rotational moment is generated due to a height difference (H in FIG. 3) between the lower end of the unit block 83 and the hanging space 83d.

As the bending of the variable strip 81 continues, the right leg gradually widens, and at this time, the angle between the inclined surfaces 83g of the unit block 83 continuously decreases. Such bending is possible until the inclined surface 83g comes into close contact with each other. 6 shows a state in which the right leg is very wide open. As shown in FIG. 6, the muscles around the hip joint may be released by spreading the legs wider.

When the right leg is symmetrical with the left leg and the right leg is rotated as much as necessary, the control dial 67a is fixed to the housing 63 using the fixing pin 68 .

7A and 7B are perspective views illustrating a modified example of a unit block 83 applied to a rehabilitation aid according to an embodiment of the present invention. FIG. 8 is a plan view illustrating a block structure in which unit blocks of FIG. 7A are arranged in a straight line, and FIG. 9 is a plan view illustrating a refraction method of the block structure of FIG. 8 .

As shown, one inclined surface of the unit block 83 forms a convex convex inclined surface 83n, and the opposite inclined surface forms a concave concave inclined surface 83m. The convex inclined surface 83n and the concave inclined surface 83m have the same curvature. Therefore, as shown in FIG. 8, when the unit blocks 83 are brought into close contact in a straight line, the convex inclined surface 83n and the concave inclined surface 83m of the adjacent unit block 83 are in close contact, and the side within the allowable limit Sliding movements in both directions are also possible. That is, while maintaining close contact, movement in the direction of arrow s in FIG. 9 can be made.

In this way, by applying the concave inclined surface 83m and the convex inclined surface 83n to the unit block 83, any part of the block structure 82 is bent or bent in the lateral direction (direction orthogonal to the bending direction described above). can make it In this description, the 'block structure' means an assembly of unit blocks in which a plurality of unit blocks 83 are closely adhered to each other in a row, that is, in close contact with each other in a row.

The fact that the unit block 83 is bent in the lateral direction means that the femur 13 can be lifted forward or removed backward. With the rehabilitation aid 20, it is possible to stably fix the hip joint and, of course, to exercise the hip joint when necessary.

In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those skilled in the art within the scope of the technical idea of the present invention.
