Minimally invasive articular surgery


The MIAS project aims to develop new minimally invasive technologies for orthopaedic surgical procedures in order to enhance the quality of the care that the surgeon delivers to the patient. The MIAS project aims to allow orthopaedic arthroscopy to take full advantage of recent advances in the field of computer assisted minimal invasive surgery (MIS), with particular emphasis on augmented reality systems and on new micro-systems technologies for the fabrication of miniaturised "intelligent" surgical tools.

The MIAS project will implement and demonstrate a complete system for arthroscopy that will be able to process and display multidimensional data (images, forces, planned procedures), and to offer the performance of micromechatronic tools in order to enable the surgeon to plan and execute minimally invasive procedures on human joints that are not possible with presently available technology, and to execute interventions with a high degree of accuracy and safety for the patient. The main result of all these aspects will be an improvement of benefits for the patient; in fact the post operative consequences will be reduced if the intervention will be as accurate and short as possible. The MIAS project is a user's needs-driven project and seeks to produce concrete and demonstrable results for clinical practice. To this aim a MIAS demonstrator for Anterior Cruciate Ligament (ACL) reconstruction will be developed and tested. In achieving its goals, the project will take advantage of the solid expertise of partners in the participation in national and EU-funded projects in related areas, and in the capabilities for exploiting research results industrially (by the participation of an industry which is a world-wide leader in instrumentation for arthroscopy/endoscopy). Several topics will be addressed by MIAS: 1) Identification of user's needs, of system specifications and of demonstrators features; 2). New and more dextrous microsurgical devices for arthroscopy; 3) Medical image processing; 4) Registration between preoperative and intraoperative images; 5) Dedicated human-machine interfaces and feedback system; 6) Safety/monitoring and quality assurance; 7) Articular tissues modelling; 8) Prototyping of MIAS systems; 9) Revision and improvement of the sub-systems based on user tests, followed by system integration; 10) User trials in Italy and Sweden, reports; guidelines for commercial exploitation. In addressing these topics, the MIAS Consortium will take advantage of previous results and instrumentation developed during previous or current EU projects.
In particular the MIAS system will: 1) allow preoperative navigation into a pseudo 3D model of a patient (or anatomic regions of interest) as obtained from images of a scanner device; 2) develop a set of novel miniature surgical tools for arthroscopy; 3) feedback position and force reactions to the surgeon; 4) develop models and a knowledge base in order to describe the physical characteristics of soft tissues, bones and joints and to develop a simulation\animation system, during and after surgery; 5) integrate various subsystems in order to realise an enhanced reality environment system for surgical procedures, and demonstrate experimentally the effectiveness of the system (the results of MIAS will be easily extended to other areas of-surgery.
