Abstract[English]
Systems and methods for tracking surgical objects during a surgical procedure are configured in consideration of data latency. Tracking data indicative of a position of a powered surgical instrument relative to patient tissue to be treated is generated by a surgical navigation system. A system latency value associated with the tracking data is determined. An actuator of the powered surgical instrument is controlled based on the system latency value and a current position of the surgical instrument relative to the patient tissue indicated by the tracking data. Further, based on a position of the surgical instrument relative to a target site of the patient tissue to be treated that is indicated by the tracking data, tracking of surgical objects in the surgical workspace other than the surgical instrument and the target site is paused.[French]
L'invention concerne des systèmes et des procédés de suivi d'objets chirurgicaux pendant une intervention chirurgicale, en tenant compte de la latence des données. Des données de suivi indiquant la position d'un instrument chirurgical motorisé par rapport au tissu biologique du patient à traiter sont générées par un système de navigation chirurgicale. Une valeur de latence de système associée aux données de suivi est déterminée. Un actionneur de l'instrument chirurgical motorisé est commandé sur la base de la valeur de latence du système et d'une position actuelle de l'instrument chirurgical par rapport au tissu biologique du patient, indiquées par les données de suivi. En outre, sur la base d'une position de l'instrument chirurgical par rapport à un site cible du tissu biologique du patient à traiter, indiquée par les données de suivi, le suivi d'objets chirurgicaux dans l'espace de travail chirurgical autre que l'instrument chirurgical et le site cible est mis en pause.
