Description

[Detailed description of the invention] [Industrial application field] The present invention is a supporter used for the treatment of knee joint diseases, especially for patients who have suffered from knee joint sway due to collateral ligament injury. The present invention relates to a knee joint supporter for controlling knee joint oscillation.

[Conventional technology]

As sports, leisure activities, and athletics for health become more popular year by year, and as the elderly population increases, the number of knee diseases is rapidly increasing. Among these, a disease called collateral ligament injury causes the knee joint to sway laterally, and requires the use of some kind of knee brace, especially when walking.

This kind of knee brace is made of a compression material that is sewn into a cylindrical shape from a composite material made by laminating elastic fabric and elastic material with relatively high foam density and firmness, such as rubber woven tape, neoprene sponge, compressed urethane, etc. type of knee joint supporter, this compression type knee joint supporter with a stay supporter with hinged stays attached to the inside and outside, or this supporter with stays for severe cases with additional reinforcement bolts attached to the thigh and lower leg parts. Supporters with stays are available. The present applicant has also proposed various supports with auxiliary belts, which are provided with auxiliary belts extending from both stays of the thigh, passing through the patella and crossing each other to reach the lower leg.

[The problem that the idea aims to solve]

The movements of the knee joint involve a combination of flexion, extension, varus, valgus, rotation, and sliding forward, backward, left, and right, and are used to perform the functions of walking, standing, and sitting. be. Knee braces that can follow such complex movements of the knee joint and control only abnormal knee joint movements have been extremely limited. Even if there were a device with such a function, the weight of the device would be too large to withstand normal wearing, the method of wearing it would be complicated, lack operability, and lack practicality. It is necessary to manufacture a brace according to the symptoms of each individual patient, and there is no satisfactory knee joint support because it lacks versatility.

The purpose of this invention is to be lightweight, easy to wear and operate, and to provide fixation force in response to the symptoms of patients with collateral ligament injuries, in whom the movement of the knee joint increases as the knee flexes from a standing position. To provide a knee joint supporter that can change the movement of the knee joint and assist the normal movement of the knee joint.

[Means to solve the problem]

This purpose, according to the present invention, consists of a main body made of elastic cloth that covers the thigh, lower leg and knee joint, and a section from the upper thigh to the lower lower leg on the left and right sides of the main body surface. A stay cover is provided on the thigh and lower leg parts of the main body to cover the stay, and one end is attached to the upper side of either of the stay covers in the lower leg part to remove the tibial roughness. A non-stretchable lower leg front belt whose other end can be connected to a metal fitting attached to the upper side of the other stay cover so as to pass over the plane, and either one of the lower leg stay covers. A non-stretchable lower leg rear belt that can be attached at one end and passed behind the lower leg part, and the other end can be connected to a metal fitting attached to the other stay cover; and a thigh stay cover. a non-elastic thigh part rear belt that can be attached to one end of the thigh part and passed behind the thigh part, and the other end can be connected to a metal fitting attached to the other stay cover; One end is attached to both sides of the lower side of either one of the stay covers, and the two ends extend diagonally upward in a V-shape so as to intersect with each other on the stay on either the inside or outside side of the knee joint, and the other end is attached to the bottom side of the stay cover. This is achieved by providing two elastic support belts that can be respectively coupled to metal fittings attached to both upper sides of the stay cover of the thigh portion belonging to the stay cover.

[Effect]

In the present invention, the main body is tightened and fixed on the knee joint and the region above and below the thigh and lower leg, and the stay is placed on the thigh with its hinge part located at the knee joint. Adjust and hold the lower leg part rear belt, lower leg part front belt, and thigh part rear belt so that they are positioned on the left and right sides from the lower leg part to the lower leg part, and hold the lower leg part front part. The tightening force of the belt compresses the tibial tuberosity and corrects it to its normal position while standing, and the supporting force of the stay and the tightening force of the support belt prevents lateral movement of the knee joint, and the knee When the knee is flexed significantly, the tension of the support belt increases as it stretches, and the control force against the lateral movement of the knee joint becomes even greater.
This reliably prevents lateral movement of the knee joint.

Next, the lower leg portion rear belt 23 is turned backward, the free end 25 is inserted into the ring-shaped metal fitting 27, folded back, and the belt 23 is fixed on itself with a planar fastener 26. Further, the thigh portion rear belt 28 is turned rearward, the free end 30 is inserted into the ring-shaped metal fitting 32, folded back, and the belt 28 itself is fixed with a planar fastener 30. Next, turn the support belt 33 from the rear side to the side so that it passes over the hinge part (or curved part) of the stay 12, turn it from the front side again to the original side, and insert the free end 37 into the ring-shaped metal fitting 42. It is then folded back and fixed on the thigh portion of the main body 1 with a sheet fastener 39. Also, rotate the support belt 34 from the front side to the side so that the support belt 34 passes over the hinge part (or curved part) of the stay 12.
Stack them on top of each other and turn from the rear side to the original side again, insert the free end 38 into the ring-shaped metal fitting 41, fold it back, and fix it on the thigh part of the main body 1 with a planar fastener 40.

When a patient wearing the knee joint supporter according to the present invention walks, under normal conditions, the knee joint is However, especially when the knee is greatly bent, the support belts 33 and 34 extend and increase the tension, increasing the lateral control force and reliably preventing outward or inward movement of the knee. Work like you do.

Note that the hole 8 provided in the position corresponding to the popliteal fossa of the main body 1 is intended to reduce the pain caused by the material of the main body becoming loose and being pinched between the thigh and lower leg when the knee is bent. Alternatively, this part can be made of thin elastic fabric.

[Effect of idea]

According to the present invention, the following effects can be obtained.

(1) Set the stay position on the lower leg side to the anatomically correct position using the front lower leg belt and rear lower leg belt, and the stay position on the thigh side using the rear thigh belt. This position does not change even if the user moves,
It can be treated without adversely affecting the knee joint.

(2) The two elastic support belts have their starting and ending ends attached to the stay covers that are held in the correct position as described above, so that the height and lateral position between the starting and ending ends do not change and are stable. Therefore, it is possible to accurately suppress pressure on the knee joint.

(3) The parts where the two elastic support belts intersect with each other on the medial and lateral sides of the knee remain on the stay even if they shift due to walking or bending, so it is necessary to locally apply only the thigh side or the lower leg side. There is no pressure, and there is no possibility of misalignment of the femoral bone and lower leg bone, causing any negative effects.

(4) By changing the tightening force of the two elastic support belts, internal rotation and external rotation can be suppressed.

(5) The forward protrusion of the knee joint can also be controlled by the moderate compression force applied to the tibial tuberosity by the lower leg front belt.

(6) It is lightweight and can be easily installed.
