Proposal of a New Design Methodology in the Surgical Domain
Résumé
Nowadays, surgical interventions are caring out more and more in Minimally Invasive Surgery (MIS) to make the post-operative constraints less painful for the patient. Traditionally, new surgical tools were designed after informal discussions between surgeons and designers despite of the existing difference between the surgeon's needs and the designer's proposition. In this paper, firstly we try to propose an innovative process design method with a better integration of the user which allows the designer to design surgical tools more adapted to surgical procedure and more supporting for the surgeon's ideas. This proposition consists in a new idea on the integration of the Scenario Based Design Methodology and the confrontation of: - Evolution of the surgical tool prototypes, - Modification of surgical procedure. This situation will be able to decrease the differences between the surgeons' needs and the designed tools and their usage. As you will see in the second part of this paper, we develop the application of the proposed Co-Evolutive Design Process methodology to the lumbar arthrodesis surgery, with the explanation of prototype and surgical procedure evolutions.
