Splayed plate for child bone malformation orthopedics

Abstract

The invention relates to the technical field of medical appliances, in particular to a splayed plate for child bone malformation orthopedics. A first counterbore hole is formed in the upper surface of a male plate; a female plate comprises a second counterbore hole and a groove; the second counterbore hole is formed in the upper surface of the female plate; a raised line on the male plate can be inserted in and matched with the groove in the female plate to form a pair of hinges and the hinges can rotate along an axis; a first screw and a second screw are inserted and connected to the first counterbore hole and the second couterbore hole; a groove channel is formed in the joint of the male plate, the female plate and the groove; a soft plate is connected to the interior of the groove channel through a clamping mechanism; and the soft plate, the male plate and the female plate are located on the same horizontal plane. According to the splayed plate, the male plate and the female plate are connected in an insertion manner to form a pair of hinges, so that medical clinical treatment requirements can be met to the greatest extent; and the splayed plate is reduced in volume, simple in structure and convenient to use, and the cost is greatly reduced, so that the price is reduced and the market application and popularization become easier.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a horoscope used for the correction of children's bone deformities. Background technique [0002] Children's knee varus and knee valgus are common lower limb deformities, which can be divided into bilateral knee varus and bilateral knee valgus. The incidence of bilateral knee valgus accounts for more than 60% of the total number of such deformities. Varus accounts for about 25%, and the other are unilateral knee varus and knee valgus. [0003] At present, there are three commonly used treatment methods: 1. External brace correction; 2. Surgical osteotomy correction; 3. Minimally invasive intervention correction. The third method-minimally invasive intervention correction is a surgery with the best correction effect and minimal loss Method, this technology is to use the potential of children's bones to continue to grow, by slowing down the growth rate of one or both sides of the...

AI Technical Summary

Problems solved by technology

At present, the commonly used surgical instruments at home and abroad are a door-shaped nail or an integral figure-of-eight plate, which is combined with two screws to complete an interference fixation. Although the use of this instrument can also partially achieve the effect of surgical treatment, its disadvantages are: Because the overall splayed plate is a whole, it deforms with the growth of the epiphysis. During the long-term slow growth period, the stress generated by the bones can easily lead to the loosening and falling off of the screws and even the fracture of the steel plate, resulting in loss of clinical effect; there are also reports in the literature that it is used clinically abroad. A hinge plate is used to correct children's bone deformities for the same purpose, but because the hinge mechanism is very complicated, difficult to process, and expensive, it has not been generally accepted and applied by clinicians
