Principles of uncertainty evaluation for measurement processes and capability studies for production processes are established in many producing enterprises to ensure capable processes. Together with further quality management methods this allows to estimate and minimize the risk of producing defective parts and of taking wrong decisions about the part’s conformity with its specification. This understanding is also desirable for a completely different field, for medical surgery. To quantify the risk of minimally invasive surgery for an individual patient, principles of metrology and production engineering are transferred to the medical domain and are exemplarily applied to minimally invasive surgery at the inner ear. It is shown how the main influencing factors, the uncertainty of the imaging and image processing and the uncertainty of the navigation process of the surgical instrument can be estimated with methods from production metrology. Furthermore, it is shown how these factors contribute to quantifying the patient’s risk of a specific surgery by contributing to a therapeutic risk indicator (TRI).
Résumé
Les principes et methodes pour estimer l’incertitude de mesure et l’aptitude de proces demanufacture ont ete etablis dans beaucoup d’entreprises pour obtenir des proces capables. En combinaisonavec d’autres methodes de gestion de qualite, le risque de fabriquer des pieces endommagees et de prendre unedecision non-fondee concernant la qualite d’une piece peut etre reduit. Ce concept est aussi souhaitable pourun autre domaine : les operations chirurgicales mini-invasives. Les principes de metrologie et de technique deproduction sont transferes dans le domaine medical pour quantifier le risque d’une operation mini-invasivepour un patient, par exemple d’une operation mini-invasive de l’oreille interne. Ce travail montre comment lesfacteurs principaux, l’incertitude d’imagerie et l’incertitude de naviguer les instruments chirurgicaux, peuventetre estimes avec les principes de metrologie manufactures. En plus, cela montre comment ces facteurs contribuent a quantifier le risque d’une operation mini-invasive et a l’index therapeutique de risque (TRI).
