Design Of Operation Platform For Personalized Medical External Fixed Brace Auxiliary System

Radius fracture is one of the most common fractures,and a good external fixation brace plays a crucial role in its recovery treatment.The traditional fixing method is generally based on gypsum or splint.Gypsum fixation has poor gas permeability,overall bulkiness,poor wearing experience and is easy to breed odor.Splint is loose and difficult to ma intain a fixed shape for a long time.While emerging brace fixings,due to their limited model types,cannot ideally matched with the patient’s limbs.Therefore,personalized medical external fixation brace will play a very important role in the development of orthopedic t reatment.Designing a system that can quickly generate personalized external fixation brace has important significance in clinical application.Combined with the existing 3D scanning and 3D printing technology,based on the special scanning hardware device for wrist which has been completed in the earlier stage,this paper designs a set of auxiliary design system operation platform for rapid printing and generation of personalized medical external fixation brace.The complex three-dimensional model modifica tion of the affected limb can be instantly performed by simple operation.Orthopedist can complete the operation without professional training of CAD so ftware,which saves a lot of energy for orthopedist and creates a more comfortable treatment experience to the patient.Investigation into orthopedist’s actual needs for the system firstly,understanding product positioning and certain illustrations on system function,performance and risk are needed to design platform and ensure that the final product meets actual needs of the orthopedist.This design utilizes multiple binocular cameras to quickly capture the affected limbs to obtain three-dimensional data of the external contour o f the limb and generate corresponding STL file.The three-dimensional data is read by the data stream file reading method and then the data format is converted to reconstruct the three-dimensional image by Open GL,which will display the model of the affected limb,modify the three-dimensional model by dissection,deformation,hollowing,and generating a buckle etc.,and finally print the model with the 3D printer for patients to wear.The operating platform’s graphical user interface is designed by Qt Creator,thus it is simple,beautiful and convenient for orthopedist to operate quickly.
