Description

technical field [0001] The invention relates to the field of medical and health technologies, and mainly relates to a non-invasive adjustable extrusion type skin expansion device for children with syndactyly. Background technique [0002] Syndrome is a congenital finger deformity in which two or more finger tissue components are pathologically connected, most of which affect the appearance and function of the hand, and can also cause psychological problems such as fragility, sensitivity, and autism in children. Surgery is the only way to treat syndactyly. In principle, it is necessary to obtain better hand function and appearance through as few operations as possible and minimal surgical complications. Generally, preschool surgery is selected. [0003] In terms of surgical design, due to the limited area of ​​interdigital skin, traditional surgical separation often results in insufficient skin on the back of the split finger or on the side of the adjacent finger, requiring f...

AI Technical Summary

Problems solved by technology

The internal fixation and stretching device linearly stretches and expands the skin through the built-in Kirschner wire of the phalanx bone, which can also solve the problem of skin defects. It no longer requires skin removal and skin grafting, but it also requires surgery and anesthesia, which also increases the pain of children. and family financial burden, and Kirschner wire implantation is likely to increase nail tract infection and increase the difficulty of nursing
