Abstract[English]
In certain embodiments, a method of identifying a composition of an aspirated material includes: controlling a surgical instrument to aspirate material through a probe that is fluidly connected with a vacuum source in an aspiration path. The method further includes estimating, during aspiration of the material, a flow rate of the material at the probe. The method further includes determining, using one or more sensors disposed along one or both of the aspiration path and infusion path, a change in pressure across the probe during aspiration. The method further includes determining a fluidic resistance of the material using the flow rate and the change in pressure, and providing feedback based, at least in part, on the fluidic resistance of the material and a reference value.[French]
Dans certains modes de réalisation, un procédé d'identification d'une composition d'un matériau aspiré consiste à : commander un instrument chirurgical pour aspirer un matériau à travers une sonde qui est en communication fluidique avec une source de vide dans un trajet d'aspiration. Le procédé consiste en outre à estimer, pendant l'aspiration du matériau, un débit du matériau au niveau de la sonde. Le procédé consiste en outre à déterminer, à l'aide d'un ou de plusieurs capteurs disposés le long du trajet d'aspiration et/ou du trajet de perfusion, un changement de pression de part et d'autre de la sonde pendant l'aspiration. Le procédé consiste en outre à déterminer une résistance fluidique du matériau à l'aide du débit et du changement de pression, et fournir une rétroaction sur la base, au moins en partie, de la résistance fluidique du matériau et d'une valeur de référence.
