METHOD AND SOFTWARE SYSTEM FOR TREATMENT PLANNING AND SURGICAL GUIDE CAD/CAM

摘要

A method and interactive software system for treatment planning and surgical guide design. In the heart of the method is a fully associative workflow integrating image processing, treatment planning, surgical kit configuration and surgical guide CAD/CAM, wherein any changes in the earlier stage will be automatically propagated to the downstream. This characteristic is referred as associativity. The software system is built upon this concept and a corresponding data model. The status, as well as the display, of the workflow at certain time point is recorded as a snapshot, with which the system can always re-enter into the status of certain point of the saved operation history. Such a snapshot is called re-enterable snapshot. In this invention, the design of surgical guides is driven by a universal surgical kit configuration tool. This approach drives surgical guide design with kit parameters and enables the professionals to plan their cases according to the kit. It also serves as a tool for the users and suppliers to define their own surgical kits as well. It supports the concept of choosing surgical kits for individual implants in a single case. This invention also includes an image processing and geometric modeling approach that is characterized as design for manufacturability and applicability. It is integrated with the feature-based CAD module and rapid prototyping technology to constitute a complete CAD/CAM solution, which is also fully associative. The surgical guides resulted from this design can better fit the patients' anatomy and can be manufactured with other CAM technologies through standard format file exporting.
