The Reaearch And Developmeng Of Compliance And Multifunction External Fixator

With the development of mining and transportation industry followed by theincreasing accidents, a large number of patients with limb fractures and deformitiesbackbone are generated. Currently, one of the main ways to treatment of limb fractures isinternal fixation. However it will destroy the microenvironment of bone end healing, alsodisturbances physiological healing and improvement of the bone. The risk of fixationfailure and secondary fracture still exists. The internal fixation becomes powerless and cannot get a satisfactory correction, when treating complex limb deformities and physicaldisabilities. Therefore, follow the development trend of orthopedic surgery, developing areset fixed micro-invasive external fixator to provide fast and effective treatment has broadmarket prospects.This report introduces a new external fixator--the compliance multifunctional externalbone fixator.It includes the following two aspects.(1)Researcher optimized the retainingclips of the support rod and external fixation pin. Fine adjustment precision holder as0.33mm.Universal fixation of external fixation pins reduces the suffering of patients,improves patient outcomes.(2)The development of related software proposes a positivesolution algorithm by way of a three-dimensional optimization which is applied to thecalculation of the prescription. There are some advantages of the algorithm. It is simple andeasy to implement programming, convenient to select the initial calculation, and has fastcalculation speed, high precision. Through laboratory exercises, it demonstrates theEffectiveness and practical of the software system.Eventually, through initially clinical validation the desired therapeutic effect isobtained.
