A method of testing a surgical system that takes advantage of the fact that in a balanced irrigation/aspiration system (inflow >= outflow) the duration of the aspiration pressure recovery to the irrigation fluid source pressure immediately following pump stop is independent of pump run time. This method provides a more reliable way of detecting restricted irrigation flow configurations not detectable by the current methods, such as marginal irrigation flow cases that could potentially lead to surgical complications (e.g. chamber collapse during post-occlusion break surge).

La présente invention a trait à un procédé d'essai d'un système chirurgical qui exploite le fait que dans un système d'irrigation/aspiration équilibré (débit entrant >= débit sortant) la durée de la récupération de pression d'aspiration à la pression source de fluide d'aspiration immédiatement après l'arrêt de la pompe est indépendante du temps de fonctionnement de la pompe. Ce procédé fournit un manière plus fiable pour détecter des configurations de flux d'irrigation restreint non détectables par les procédés existants, telles que des cas d'irrigation marginale qui pourraient entraîner des complications chirurgicales (par exemple, l'affaissement de la chambre lors d'une surpression d'interruption suite à une occlusion)
