Description

{Medical Rehabilitation Orthosis for Joint}

The present invention relates to a joint rehabilitation orthosis, and more specifically, to a medical joint rehabilitation orthosis that can improve the efficiency of rehabilitation treatment by preventing strain on the joints until the joints are fully recovered.

Patients who have to lie down for a long time due to surgery tend to gradually lose muscle mass and become weak because they are unable to move for a long period of time. For example, the joints and unit muscles necessary for walking become weakened and stiff. For example, most fracture patients are unable to walk properly after the cast or fixator is removed because they are kept immobile in a cast or fixator for a long period of time. In addition, even without surgery, walking strength may weaken due to aging, and it is important for elderly people with weakened walking ability to increase their unit muscle strength and maintain a state in which they can walk freely through joint movement.

On the other hand, weakness of the muscles or ligaments of the lower extremities can cause genu valgus or genu varum. Knee valgus or knee varus causes knee pain and various joint-related diseases, and also puts a strain on the hip joint. Additionally, internal rotation of the hip joint has a negative effect on the knee and ankle joints as well as the lumbar spine.

To solve various problems resulting from weakness of lower limb muscles, various rehabilitation services, including physical therapy, are provided, and rehabilitation aids worn on the body are also used.

As a background technology for this related invention, an orthosis capable of controlling pelvic and hip joint rotation has been disclosed through Domestic Patent Publication No. 10-2014538.

The disclosed orthosis includes a wearing portion that is worn and fixed to the user's waist or pelvic region and has a pair of side supports protruding in the direction of both lower legs; A first wearing belt that is each coupled to a pair of side supports and is worn and fixed to the upper part of the user's thigh, and a second wearing part that falls below the first wearing part and is worn and fixed to the lower part of the user's thigh; Both ends are coupled to the first and second wearing bands, respectively, and have a spring-shaped correction band that surrounds the thigh and is formed to generate a rotational force.

However, the conventional brace described above is uncomfortable to wear because both legs must be placed on a spring-type brace, and is heavy, making it somewhat inconvenient to use.

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

Basically, the joint rehabilitation orthosis of the present invention protects the joint by fixing it (until it is fully recovered). For example, it blocks unnecessary movement of joints that have undergone surgery to encourage rapid recovery. These braces can be applied to all joints of the body, and, for example, can be used to assist rehabilitation of the hip joint as shown in Figure 1.

FIG. 1 is a diagram for explaining the basic configuration of a medical joint rehabilitation orthosis 20 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the medical joint rehabilitation orthosis shown in FIG. 1. Additionally, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2, and FIG. 4 is a cut-away perspective view of the tension adjusting portion of FIG. 1.

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

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

Additionally, the rehabilitation orthosis 20 can be applied to other joints. For example, rehabilitation of the knee joint can be performed by fixing the first wearing 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 an elastic belt-like member that wraps around the waist of the body 10 and presses it. The wearing band 41 supports the upper end of the power transmission unit 80, and the structure of the wearing band 41 can be changed as long as it can perform this function.

The wearing maintenance part maintains the wearing band 41 wrapped around the waist and includes a plurality of adhesive cloths 42 and 43. The adhesive fabrics 42 and 43 are Velcro fabrics, and when the wearing band 41 is wrapped around the waist, they face each other and are fixed by adhesive. In addition to adhesive cloth, other fastening means such as buttons or hooks can also be applied.

The first support panel 61 is a plate-shaped member of a certain thickness fixed to the outer surface of the wearing band 41, and supports one end of the housing 63 and the variable strip 81. The first support panel 61 can be manufactured from synthetic resin.

The second wearing fixing part (50) has the same configuration as the first wearing fixing part (40). The second wearing fixing part 50 includes a wearing band 51 that wraps around the thigh 13, a wearing holding part that maintains the wearing band wrapped around the thigh, and is fixed to the outer surface of the wearing band 51 and provides a supporting force. It is provided with a second support panel (55). The wear-retaining portion is a pair of adhesive cloths 52 and 53 that are bonded and fixed to each other. When the thigh is wrapped with the unfolded wearing band (51), the adhesive cloth (52, 53) automatically faces each other. The second support panel 55, like the first support panel 61, is a plate-shaped member with a certain thickness and is made of synthetic resin.

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

As shown in detail in FIG. 4, the operation unit 60 includes a housing 63, an introduction guider 64, a tension reel 65, a drive gear 67L, a torque transmission shaft 67e, and an operation dial 67a. ), and includes a fixing pin (68).

The housing 63 is a hollow disk-shaped member that provides a receiving space 63a, and its bottom is closely fixed to the outer surface of the first support panel 61. Additionally, a plurality of locking holes 63e are formed on the upper surface of the housing 63. The locking hole 63e is a through hole arranged at an equal angle around the torque transmission axis 67e, and accommodates 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 receiving 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 rotatably supports the tension reel 65. In particular, the tension reel 65 is provided with a gear portion 65c. The gear portion 65c is a portion that receives the rotational torque input from the operation dial 67a and meshes with the driving gear 67f.

The drive gear 67f is a gear meshing with the gear portion 65c of the tension reel and has a torque transmission shaft 67e at the center. The torque transmission shaft 67e penetrates the upper plate 63b and is coupled to the operation dial 67a outside the housing 63.

The operation dial 67a is a disk-shaped member that is handled by the user. The rotational force of the operation dial 67a is transmitted to the gear portion 65c through 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 tension 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 on 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 the vertical upper part of any locking hole (63e), inserting the fixing pin (68) into the pin hole (67b), the lower end of the fixing pin (68) is inserted into the locking hole (63e). This prevents the operation dial 67a from rotating. Reference numeral 67c is a holder. The holder (67c) is connected to the fixing pin (68) through a loss prevention string (69). The fixing pin 68 is held in the holder 67c by the loss prevention string 69, so there is no fear of it being lost.

Meanwhile, the power transmission unit 80, in a state in which the first wearing fixing part 40 and the second wearing fixing part 50 are connected, receives the tension provided from the operating unit and bends itself, and applies the bending force to the second wearing fixing part 50. It is delivered to the wearing fixing unit (50). The bending force transmitted to the second wearing fixing part 50 is used as a force to pull the second wearing fixing part 50 in the direction of arrow k. The force acting in the direction of arrow k physically moves the joint in an abnormal state and returns it to its normal state.

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

The variable strip 81 is a flexible member that extends in the longitudinal direction and has a certain width, and has side grooves 81a at both ends in the width direction. The side groove (81a) is a gap that accommodates and supports 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 blocks 83 are hexahedral-shaped members with a narrow upper surface and a wide lower surface, like keys on a computer keyboard, and a plurality of them are arranged in a row at the top of the variable strip 81, and adjacent unit blocks 83 The lower parts are in close contact with each other.

The lower part of the unit block 83 is in close contact, but the overall part is spread upward. The reason it is formed to spread 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 arrow k direction 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. As long as the separation prevention protrusion 83f is maintained in the side groove 81a, the unit block 83 is not separated from the variable strip 81.

As mentioned above, the unit block 83 is a hexahedron in which the area of the lower end is larger than the area of the upper end (excluding the separation prevention protrusion), so it has inclined surfaces 83g on all four sides. Among the slopes 83g, the angle θ formed by the opposing slopes 83g of neighboring unit blocks can be designed in various ways. The included angle when the variable strip 81 is spread out in a straight line may be 10 to 30 degrees. The angle between legs increases when you close your legs to one side, and decreases when you spread them outward.

Additionally, each unit block 83 is provided with a through hole 83a and a hanging space 83d. The through hole (83a) is a passage penetrating in a direction parallel to the longitudinal direction of the variable strip (81) and can allow the tension wire (71) to pass therethrough. The tension wire 71 passes through the through hole 83a of each unit block 83 arranged in a row, one end is fixed to the hanging space 83d of the terminal unit block 83, and the other end is fixed to the locking space 83d of the terminal unit block 83. 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 entrance 83c. The locking space (83d) detachably accommodates and fixes the locking ball (71a) of the tension wire (71).

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

With the locking ball 71a inserted into the locking space 73d (of the end unit block 83 in the direction of the second wearing fixing part), when the operation dial 67a is rotated in the direction of arrow m, the power transmission unit 80 is pulled in the direction of arrow f and finally bent in the direction of arrow k. The reason why such bending is possible is because an inclined surface 83g is formed on the unit block 83. Additionally, when rotating the control dial 67a, bending begins more easily by pressing approximately the center part of the power transmission unit 80 in the direction of arrow p.

Figures 5 and 6 are diagrams for explaining the operation of the rehabilitation assistive device 20 according to an embodiment of the present invention.

As shown, the first wearing fixing part 40 and the first wearing fixing part 40 are installed above the patient's hip 11, where the right leg (left side in the drawing) is gathered inward (regardless of the patient's will), and on the right thigh 13. Two wearing fixing parts (50) are each installed. The rehabilitation aid 20 spreads the right leg outward and applies force to the patient so that he or she can stand.

After the installation of the first and second wearing fixing parts (40, 50) is completed, when the operation dial (67a) is rotated in the direction of arrow m, the tension wire (71) is tensioned and the variable strip (81) is bent in the direction of arrow k. I order it. The reason why such bending is possible is because a rotation moment occurs due to the 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 spreads, and at this time, the angle between the inclined surfaces 83g of the unit block 83 continues to decrease. This bending is possible until the inclined surfaces 83g come into close contact. Figure 6 shows the right leg spread very wide. As shown in Figure 6, you can also spread your legs wider to relax the muscles around the hip joint.

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

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

As shown, the slope on one side of the unit block 83 forms a convex slope (83n), and the slope on the opposite side forms a concave slope (83m). The curvature of the convex slope (83n) and the concave slope (83m) are the same. Therefore, when the unit blocks 83 are brought into close contact with each other in a straight line as shown in FIG. 8, the convex slope 83n and the concave slope 83m of the neighboring unit blocks 83 come into close contact, and the sides within the allowable limit are in close contact. Sliding movement in either direction is also possible. That is, while maintaining close contact, movement in the direction indicated by arrow s in FIG. 9 can be achieved.

In this way, by applying the concave slope 83m and the convex slope 83n to the unit block 83, any part of the block structure 82 can be bent or refracted in the lateral direction (direction perpendicular to the bending direction described above). You can do it. The 'block structure' in this description refers to a collection of unit blocks in which a plurality of unit blocks 83 are closely adhered in a row, that is, in a row.

That the unit block 83 is bent laterally means that the thigh portion 13 can be lifted forward or pulled backward. The rehabilitation brace 20 not only stably fixes the hip joint, but also allows hip joint exercise when necessary.

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 can be made by those skilled in the art within the scope of the technical idea of the present invention.
