A Primary Experiment Of The Resistance Navigation Technology For Pedicle Screw Placement

Summary: Video technology judge, good or bad measure pedicle screw technology has been applied to more than half the century, It implants can show the location and the relationship with the organization structure near Pedicle, However, because of the limited level of technology, the problem still exists, Issues such as the constructed defect shadow, Video technology has its own resolution and sensitive materials , two position is too close to the metal and the use of materials, images will become blurred even enlarged the scope ,This makes it difficult to distinguish between the screws are available piece of structural damage Pedicle, Even not sure whether access to the spinal cord., Therefore, to improve and enhance the image of the plant materials and learning technologies at the same time, we also try to try other ways of monitoring, Hope to be able to compensate for the impact of technical deficiencies.[Objective] CT in imaging science experiment has proved blunt head pedicle bore superior to the general category of sharp head industrial safety . On the basis of the experiments and the methods used to monitor propulsive again compare two pedicle bore: sharp pedicle bore, blunt head pedicle bore shaped safety. At the same time, it will use various methods of comparison, Several different methods, including the use of: Little-coils-promote method: propulsive as the main means of escape in a small rotary; Micro-into-rotation method: a...
