Title
(EN) NEEDLE INSERTION INTO SUBCUTANEOUS TARGET
(FR) INSERTION D'AIGUILLE DANS UNE CIBLE SOUS-CUTANÉE
Abstract
(EN)
Real-time compensation of a needle path into tissue comprises detecting initiation of a needle insertion operation, monitoring a condition associated with the detected needle insertion operation as the needle follows a first path toward a target point, and performing a dynamic compensation modification where a change is detected in the monitored condition that deviates beyond a first predetermined threshold. Dynamic compensation is carried out by calculating a correction necessary to compensate the needle insertion operation based upon the detected change in the monitored condition, generating a likelihood that the calculated correction will result in a successful needle insertion, and transmitting a command to a delivery system that effectuates insertion of the needle based upon the calculated correction where the generated likelihood exceeds a second predetermined threshold, otherwise transmitting a command to stop the needle insertion operation before the needle breaches the tissue.
(FR)
Selon l'invention, la compensation en temps réel d'un trajet d'aiguille dans un tissu comprend la détection de l'initiation d'une opération d'insertion d'aiguille, la surveillance d'une condition associée à l'opération d'insertion d'aiguille détectée lorsque l'aiguille suit un premier trajet vers un point cible, et la réalisation d'une modification de compensation dynamique dans laquelle un changement est détecté dans la condition surveillée qui s'écarte d'un premier seuil prédéterminé. Une compensation dynamique est effectuée par le calcul d'une correction nécessaire afin de compenser l'opération d'insertion d'aiguille sur la base du changement détecté dans l'état surveillé, la génération d'une probabilité que la correction calculée conduira à une insertion d'aiguille réussie, et la transmission d'une commande à un système de distribution qui effectue l'insertion de l'aiguille sur la base de la correction calculée lorsque la probabilité générée dépasse un second seuil prédéterminé, par ailleurs la transmission d'une commande permettant d'arrêter l'opération d'insertion d'aiguille avant que l'aiguille ne fasse de brèche dans le tissu.
