Description

Patella fixing band

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to a patella fixed band.

Background

The knee joint is the place that upper and lower leg bone meets, there is the meniscus in the middle of, there is the kneecap in the front, the kneecap is the biggest unginned bone of human body, the embedding is in four head of the femur tendon, for triangular flat bone, do not link to each other with other bones, therefore the human body is when carrying out violent motion, the kneecap has the possibility of taking place the aversion, at this moment just need wear the kneecap area on the knee joint, the kneecap area can be fixed the kneecap on relatively stable position, in order to guarantee that it is not hurt, and after the meniscus is injured, use the kneecap area can reduce the wearing and tearing of meniscus, slow down pain, thereby play the effect of protection knee joint.

The clinical manifestations of patellar fracture are local obvious swelling and pain, difficulty in knee joint movement, incapability of straightening automatically, and frequent anterior patellar subcutaneous ecchymosis and knee joint hematocele. Patellar fractures are often caused by direct or indirect violence, with the latter being more common. The direct brute force causes most of the patients with comminuted fracture, the quadriceps femoris fascia and the joint capsule on both sides of the patella are generally complete, and the knee stretching function is less affected; in indirect violence, the quadriceps femoris muscle contracts strongly, the fascia of the quadriceps femoris muscle and the joint capsule on both sides of the patella are broken, the two bones are separated and displaced, and the knee stretching device is damaged, so that the knee stretching function can be influenced if incorrect treatment is carried out. Meanwhile, the patellar fracture belongs to lower limb fracture, has high resetting requirement, is difficult to maintain continuous alignment, needs continuous traction treatment, has long fixing time, and can cause serious influence on both physiological and psychological aspects of patients.

At present, the patella fracture is usually fixed externally by using bandages clinically, common bandages comprise cotton yarn bandages, plaster bandages, resin bandages and elastic bandages, and because the appearances of various bandages are planar structures and do not conform to the appearance of the hemispherical raised patella, the constraining force cannot be uniformly applied to each part of the patella fracture during fixing, so that the angulation deformity is easily caused to cause the fixing failure.
