Abstract
(EN)
A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.

(FR)
L'invention concerne un système fournissant une assistance spécialisée en matière d'intervention sur la base de données spécifiques d'un patient acquises à partir d'instruments chirurgicaux intégrant des capteurs sur leur surface de travail, d'un ou plusieurs capteurs de référence placés autour du patient, de capteurs implantés avant, pendant ou après l'intervention, d'antécédents médicaux personnels du patient et d'appareils de surveillance de l'état du patient. Certains modes de réalisation comprennent un système comportant un instrument chirurgical doté d'un capteur destiné à générer un signal indiquant une propriété d'un tissu cible du patient, lequel signal est converti en un ensemble de données actuel puis stocké. Une unité de traitement compare cet ensemble de données actuel avec d'autres ensembles de données préalablement stockés et utilise cette comparaison pour évaluer une condition physique du tissu cible et/ou assister une intervention effectuée sur le tissu.
