Засіб для накісткового остеосинтезу опорно-рухового апарату людини

Abstract

The thesis research contains the results of investigations, aimed at increasing efficiency of the existing methods, models, ways and systems of external osteosynthesis, where all drawbacks and problematic issues were revealed, regarding fixation of fractures of damaged bones, presence of means of electronic control over the state of fixation the device and the bone, such problems could be solved by creating appropriate models, methods and bio-engineering system of osteosynthesis. Content models were created for determination of qualitative-quantitative parameters of formations on the body of fixing devices, differing in arrangement of fixing and blocking elements, located thereupon, with simultaneous determination of limits of such formations, it ensuring efficient fixation of external bone structures, providing an opportunity of evaluating their tensile strength. The experimental study of the strain-strain state of the nail clippers at different numbers and the location of the fixing elements for simple and complex types of deformation allowed to identify openings that are common to most types of loads and confirmed their importance for the treatment of lumbar diaphyseal fracture of the femur. A biological -engineering system of osteo-synthesis was developed, its innovative character being in introducing into its structure the means of electronic control over the state of bone-fixing device, in the form of autonomous and implanted bio-telemetric module, it providing a doctor with the opportunity to increase the precision of application of bone fixing devices by some 11-14%.
