Abstract

The invention relates to a deformed hand shape orthodontic treatment instrument, and belongs to the technical field of medical instruments, in particular to an adjustable type deformed hand orthosis to solve the problem of the lack of mature and standardized deformed hand traction equipment. The orthosis comprises a plurality of Kirschner wires with one end vertically embedded in the metacarpal bone, an arcuate or semicircular support piece fixed at the other end of each of the Kirschner wires perpendicular to the back of the hand, a hollow support rod with one end passing through and fixed to the support piece and the other end extending to the upper part of the finger and parallel to the back of the hand, and a backstop wire stranding device fixed to the back of the support piece; the orthosis further comprises a stay wire, one end of the stay wire passes through the hollow support rod and is fixed to and twined around the backstop wire stranding device, and the other end is connected with a tension sensor or spring scale in series and then is connected with a hook or fingertip sleeve, wherein the hook is hooked with a connector embedded in the fingertip or directly connected to the fingertip in a sleeving mode through the fingertip sleeve. The orthosis is stable and adjustable in generated traction force value and direction, and is capable of providing accurate values to provide accurate data for subsequent treatment and clinical research.

Description

[0001] The invention relates to a shape correction treatment instrument for deformed hands, in particular to deformed hands caused by post-burn scar contracture, which belongs to the technical field of medical devices, in particular to an adjustable deformed hand orthosis. Background technique [0002] The orthodontic treatment of the claw-shaped hand after burns is complicated and takes a long time, and the deformity is not completely corrected by surgery and is prone to recurrence. While the scar is released by surgery, it is also easy to cause new scar formation; if there is a need for skin grafting, the retraction rate of the skin graft is as high as 30-50%, and the contracture of tendons, joint capsules, ligaments, blood vessels, and nerves is difficult to be safe and effective through surgery release. Aiming at the above problems, some scholars cite the classic bone traction theory and apply bone traction technology to the treatment of burnt claw hands, and have achieved...
