Description

An improved adjustable lower limb fixation orthosis

technical field

The invention relates to the technical field of medical devices, in particular to an improved adjustable fixed orthosis for lower limbs.

Background technique

Trauma and disease of the lower limbs, postoperative or conservative treatment of knee ligament and bone injuries, fractures of ankle, foot and distal tibia and fibula are common clinical fractures, mostly caused by falls, falls, collisions and traffic accidents. Arteries often rupture, resulting in fractures and ligament injuries that are difficult to heal, and in severe cases, malunions can occur, seriously affecting the normal life of patients. At present, in clinical practice, gypsum and fixation plate are often used for stabilization after surgery. On the one hand, gypsum fixation has poor fixation effect, and on the other hand, it has no versatility for multi-angle fixation for different patients. Medical personnel lack a general-purpose equipment for fixation. It is suitable for patients in different states, which brings inconvenience to the work of medical staff. After the plaster is fixed, the patient's feet will often swing left and right when they are left on the ground for a long time. When the shortcomings are serious, such as airtight, difficult to adjust, easy to be allergic, inconvenient to adjust, too heavy, etc. affect the therapeutic effect.

Chinese patent CN 204351984U discloses an adjustable lower limb fixed orthosis, which includes two parts, an upper orthosis and a lower orthosis. The upper orthosis and the lower orthosis are hingedly connected by connecting plates arranged on both sides, and the height can be adjusted. , adjust the joint angle, the lower orthosis includes a hinged tibiofibular fixator and ankle fixer, the upper orthosis and the lower orthosis are combined and assembled in a semi-open arc-shaped structure, and there are several fixing straps at the opening. Two assembled concave fixing grooves are respectively arranged on the rear side of the device and the tibiofibular fixator, and the corresponding assembled concave fixing grooves are locked and fixed by bolts through locking blocks arranged in the grooves. The new adjustable below-the-knee fixed orthosis can adjust the width of the legs and ankles in sections according to the patient's fat and thin needs, and has good adaptability. By adjusting the hinge screws of the tibiofibular fixator and ankle fixer, the patient's ankle joint can be flexed and extended. The angle is free, and at the same time, the bottom of the internal fixation groove is set as a plane to prevent the patient's legs from swinging left and right. However, the connecting plate used to connect the orthosis and the lower orthosis, that is, the joint support, does not have a protective cover to protect the angle disc, which is easy to cause damage to the angle disc; and most of the joint supports on the market use adjustment holes. The adjustment process is cumbersome; moreover, the angle plate of the joint support bar on the market adopts a circular design, which does not match the direction of human bones.

Chinese patent CN 207506673U discloses a joint support bar with an elongated angle plate, including a first connecting rod, a second connecting rod, an angle plate, a fixing block and a protective cover; One end of the block and one end of the protective cover arranged above the angle plate are hinged through a rotating shaft, and the fixed block is connected to the protective cover in rotation; a lower stopper is arranged below the angle plate; two left and right ends of the fixed block are connected Control line, the other end of the control line is connected with an adjustment pin, and the left and right ends of the angle plate and the lower block are provided with a plurality of pin holes for insertion of the adjustment pin, and the design of the joint support with a long angle plate is reasonable. The angle plate can be effectively protected by adding a protective cover to avoid damage to the angle plate caused by bumps, and at the same time increase the aesthetics; the adjustment method is easier by adjusting the bolt; the long angle plate adopted is more in line with the direction of the human upper limb bones.
