Portable spastic type leg stretching device

Abstract

The invention relates to a portable spastic type leg stretching device. The portable spastic type leg stretching device comprises a seat, a leg stretching device body and a protractor, wherein the seat comprises a seat board, a folding chair back and a positioning pin. The folding chair back is hinged to the seat board, and the positioning pin is used for making the seat board connected with the folding chair back so that the seat board keeps relatively perpendicular to the folding chair back. An upper insertion ring is fixedly connected with the back side of the folding chair back, a lower insertion ring is fixedly connected with the seat board, and the positioning pin penetrates through the upper insertion ring and the lower insertion ring in sequence. The leg stretching device body comprises two leg stretching plates, a threaded hole is formed in the upper surface of the seat board, a fastening bolt is in threaded connection with the inside of the threaded hole, the two leg stretching plates are both sleeved with the fastening bolt, and the two leg stretching plates can rotate along a rotary shaft. The two side edges, mutually close to each other, of the two leg stretching plates are fixedly connected with edge plates respectively, and the edge plates are vertically fixedly connected with the side edges of the leg stretching plates; the protractor is arranged under the leg stretching device body. Compared with the prior art, the portable spastic type leg stretching device has the advantages that the structure is simple, the manufacturing cost is low, and the applicationrange is wide.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable spasm-type leg splitter. Background technique [0002] The incidence rate of cerebral palsy is about 1.8%-4% in China, and the total number of children with cerebral palsy reaches 4-5 million, of which spastic cerebral palsy accounts for 60%-70% of the total number of cerebral palsy. Spastic cerebral palsy refers to movement and postural disturbances caused by non-progressive damage caused by immature brain underdevelopment for various reasons. Children with spastic cerebral palsy exhibit increased muscle tension in some muscle groups, forming spasms, and long-term spasticity patterns lead to joint contracture deformities, among which hip joint flexion and adduction deformity and knee joint flexion deformity are common secondary to musculoskeletal system in children with spastic cerebral palsy. damage. [0003] The hip flexion-adduction deformity in children ...

Problems solved by technology

There are the following technical defects in the use of this orthosis: ①The angle of the legs cannot be displayed on the orthosis, and the angle of the legs can only be roughly calculated by the medical staff based on the condition of the child and their own clinical experience. There will inevitably be deviations, and the child's thigh adductor and femur are at risk of injury and fracture; ②Because the angle of the split leg cannot be displayed, the correction operation can only be performed by experienced medical staff, and non-professionals cannot perform it. There are great limitations in it, and it cannot be popularized and used; ③The volume is huge, and it is very inconvenient to carry
