Description

A light composable lower extremity orthosis

technical field

The utility model relates to the technical field of medical devices, in particular to a light composable lower extremity orthosis.

Background technique

In actual medical treatment, ASIA grade A or B patients with complete spinal cord injury from T9 to T12, their lower limb strength is grade 0. When wearing ordinary plastic or resin braces for training, due to the heavy material of ordinary lower extremity braces, it is easy to As a result, the patient cannot complete the training action and affects the treatment effect. Furthermore, these patients are bedridden for a long time, so the degree of movement of the lower extremities depends on the care of the caregivers. The care of the caregivers is different, and the degree of ankle contracture of the lower extremities and the degree of ankle varus of the patients are also different. The braces cannot be targeted for treatment of patients with different conditions. Some patients have recovered partially through rehabilitation training, and have partially flexed their hips and extended their knees using walkers or crutches. There is no need for a long brace to support it, but the existing brace does not have the function of disassembly and adjustment, so it increases the burden of exercise training for these patients to a certain extent, limits the voluntary movement ability of these patients, and reduces the the patient's exercise effect.

In the prior art, a patent document such as CN211797105U proposes a lower extremity wearing brace, which includes a calf fixing bracket and a foot fixing bracket with adjustable straps. The calf fixing bracket is hinged, a first airbag is arranged inside the foot fixing bracket, the first airbag is communicated with the first dual-purpose pump, the inside of the calf fixing bracket is provided with a second airbag, the second airbag is communicated with the second dual-purpose pump, and the foot A telescopic device is also arranged between the upper fixing bracket and the lower leg fixing bracket; the lower limb wearing support also includes a main control device. The purpose of the prior art is to provide a device that can wrap the patient's foot and calf, play a certain buffering role, reduce the friction between the patient's foot and calf and the brace, and can adapt to the relatively thin calf and foot. At the same time, the angle between the foot and the calf can be easily adjusted to achieve passive and active functional rehabilitation training of lower limbs wearing braces. However, the brace does not have a disassembly function and cannot meet the different exercise training needs of patients at various stages of recovery to the greatest extent.

In the prior art, a patent document such as CN204890288U discloses a lower limb fixation support, which includes a support support sheet and a sole support plate, and the support support sheet is provided with several ventilation holes; the inner side of the support support sheet The inner lining is arranged; the outer edges of the brace support piece and the sole support plate are provided with adhesive tapes. The lower limb fixation brace with the above structure can better prevent foot drop due to the provision of a sole plate; a plurality of ventilation holes are arranged on the brace holder, which improves the air permeability; the inner side of the brace holder is provided with a The inner lining is to prevent the skin from being compressed; the adhesive tape is used for fixation, so that the lower limb fixation support closely fits the fracture site, with good comfort and a scientific and reasonable structure. A preferred solution is that an adjustable horizontal bar structure is provided along the lateral direction of the sole support plate, so that the sole support plate has a T-shaped structure. The arrangement of the horizontal bar structure reduces the incidence of varus deformity of the foot, and the adjustable setting can not only adapt to the patient's body position adjustment when lying in bed, but also facilitate the movement of the ground, preventing the T-shaped structure from causing obstacles to the functional exercise of the affected limb. However, the device cannot set a ruler for the inversion of the patient's ankle joint, nor can it be visually displayed through the brace, and cannot be well adjusted for the patient's condition during use.

In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, because the inventor has studied a large number of documents and patents when making the present utility model, but the space limit does not list all the details and contents in detail. The present invention does not have the features of the prior art, on the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art.
