Claims (9)

  1. A main body that wraps around the user's knee area and is fixed to the leg; A fixing part disposed in the main body and having a variable structure capable of changing size to be fixed to the user's patella; A connecting part that is fixed on both longitudinal sides to the upper and lower sides of the main body part based on the above-mentioned fixing part and connected to the fixing part so that a supporting force is transmitted to the patella through the fixing part; and A tension adjustment unit connected to the above-mentioned connecting unit and adjusting the tension of the above-mentioned connecting unit so as to change the magnitude of the support force applied to the patella; is included. The above main body is provided with a pair of rotational support members positioned on the outer and inner sides of the knee, respectively, relative to the patella, and The above-mentioned rotary support includes an upper hinge shaft and a lower hinge shaft rotatably connected to each other, wherein, with respect to the patella, the end of the upper hinge shaft is connected to the upper side of the main body, and the end of the lower hinge shaft is connected to the lower side of the main body. A knee brace for preventing patellar dislocation, comprising a plurality of fixed main body parts arranged spaced apart from each other and a fixed connecting part having elasticity that connects the fixed main bodies adjacent to each other, wherein the fixed part has a curved shape.
  2. In claim 1, The above connecting part is a knee brace that prevents patellar dislocation by generating a supporting force that pulls the patella in the direction between the user's two legs.
  3. In claim 1 or claim 2, A knee brace for preventing patellar dislocation, wherein both longitudinal sides of the above-mentioned connecting part are positioned on the inside of the knee relative to the patella, rather than on the inside of the fixing part.
  4. In claim 1 or claim 2, The above-mentioned connecting part is a knee brace for preventing patellar dislocation, in which at least a portion is made of an elastic material.
  5. In claim 1, A knee brace for preventing patellar dislocation, wherein the above-mentioned fixed portion is further provided with a connecting guide portion connected to the above-mentioned connecting portion.
  6. In claim 5, The above connecting guide part is a knee brace for preventing patellar dislocation having a curved shape.
  7. delete
  8. delete
  9. In claim 1, The above tension adjustment part A first tension adjustment means for adjusting the tension of a connecting part positioned between the fixed part and the upper end of the main body part, which is positioned above the fixed part and based on the fixed part, and A knee brace for preventing patellar dislocation, comprising a second tension adjustment means for adjusting the tension of a connecting part positioned between the fixed part and the lower end of the main body part, which is positioned below the fixed part.

Description

Patellar Dislocation Protection Knee Brace The present invention relates to a knee brace that prevents patellar dislocation and ligament damage caused by excessive movement of the knee joint. In general, the knee joint is an essential joint for human movement, serving to store and release energy and support body weight. However, the knee is a part where injuries and diseases frequently occur due to excessive use of the joints in the wrong way during sports and physical activities or a lack of exercise. There is a possibility of conditions such as meniscal injury, patellofemoral syndrome, anterior cruciate ligament rupture, collateral ligament injury, chondromalacia, and patella dislocation. Since damage to the knee's soft tissues accelerates degenerative arthritis, continuous management is very important once the injury occurs. However, as the number of people visiting hospitals complaining of knee pain increases due to insufficient attention and management and the entry into an aging society, joints are preserved through physical therapy, medication, and cartilage regeneration procedures in the early and middle stages of degenerative arthritis where cartilage damage is relatively minor; conversely, knee replacement surgery is performed in cases of severe pain or leg deformity. Although knee braces have recently been used to protect the knee joint, conventional knee braces focus solely on fixing the kneecap and cannot reliably prevent patellar dislocation. Furthermore, they have limitations in use that do not align with biomechanical and linear dislocation models, such as failing to accurately support the knee according to the user's specific knee size or shape and causing discomfort. Related technology regarding such a knee brace is disclosed in Korean Registered Patent Publication No. 10-1230458 (February 6, 2013). FIG. 1 is a schematic diagram of a knee brace for preventing patellar dislocation according to one embodiment of the present invention. FIG. 2 is a diagram showing the usage state of a knee brace for preventing patellar dislocation according to one embodiment of the present invention. Figure 3 is a side view of the fixed part shown in Figure 1. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings. Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the present invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Referring to FIGS. 1 to 3, a knee brace for preventing patellar dislocation according to one embodiment of the present invention may include a main body part (100), a fixing part (200), a connecting part (300), and a tension adjustment part (400). The above main body (100) can be positioned to wrap around the user's knee and be fixed to the leg. The above-mentioned main body (100) may be made of an elastic material that is flexible enough to be stably fixed to the leg according to the user. The above main body (100) may have a tubular shape that is open to the upper and lower sides to completely wrap around the circumference of the leg, or it may be composed of a pad that wraps only a part of the entire circumference of the leg and a band that is detachably connected to each other while positioned on both sides of the pad. Additionally, the main body (100) may be provided with a pair of rotational support members (110) positioned on the outside and inside of the knee, respectively, relative to the patella. The above-mentioned rotational support member (110) transmits a supporting force to the knee joint when bending of the knee joint occurs. For example, the rotational support member (110) may include an upper hinge shaft (111) with one end connected to the upper side of the main body (100) with respect to the patella, and a lower hinge shaft (112) with one end connected to the lower side of the main body (100) with respect to the patella. In addition, the other end of the upper hinge shaft (111) and the other end of the lower hinge shaft (112) may be connected to each other by a hinge so as to be rotatable. Here, the upper hinge shaft (111) and the lower hinge shaft (112) may be provided to have elastic or non-elastic properties, or at least have some elastic properties. The above fixed part (200) can be placed on the main body part (100). The above-mentioned fixing part (200) can be positioned to be fixed in a state that wraps around the user's patella. The above fixing part (200) may have a variable structure that allows for size changes so that accurate fixation is achieved at the patella regardless of the size of the knee according to the user, more preferably the size of the patella. For example, the above-mentioned fixed part (
