Abstract
Un sistema para regular la presión en un sistema quirúrgico oftálmico (100) que comprende: un manguito (122) sostenido coaxialmente sobre una aguja (128) para definir un pasaje de flujo entre el manguito y la aguja a través del cual se comunica fluido de irrigación al sitio quirúrgico, y un pasaje de la aguja (129) a través del cual se aspira fluido desde el sitio quirúrgico, el manguito (122) y la aguja (128) para inserción en un medio a través de una incisión (112) de un tamaño predeterminado; un recipiente (130) configurado para proporcionar una presión de infusión ajustable para forzar un flujo de fluido de irrigación dentro del recipiente al manguito (122), para infusión al sitio quirúrgico; una fuente de vacío (140) configurada para establecer un vacío para forzar una aspiración de fluido desde el sitio quirúrgico a través del pasaje de la aguja (129); un sensor (160) para proporcionar una señal indicativa del vacío que está siendo aplicado; un dispositivo para detectar o estimar el flujo (162) para proporcionar una señal indicativa de un caudal de fluido que está siendo aspirado desde el sitio quirúrgico; y un controlador (200) configurado para recibir una entrada de un tamaño de la aguja, un tamaño del manguito y el tamaño de la incisión, y para estimar una presión intraocular del ojo en base a la presión de infusión menos una caída de presión debida a una resistencia predeterminada al flujo de fluido, flujo de fluido que no incluye ningún flujo de fuga predicho y donde el controlador (200) está configurado para obtener una estimación más afinada de la presión intraocular del ojo en base a la presión de infusión y una combinación del caudal de fluido detectado y un caudal de fuga predicho de fluido que sale de la incisión (112) seleccionado a partir de una tabla de consulta en base al tamaño de la aguja, el tamaño del manguito y el tamaño de la incisión, donde el controlador (200) usa la estimación afinada para controlar el flujo de fluido para mantener una presión intraocular deseada.
