Abstract

Sistema (110) quirúrgico, que presenta un control de retroalimentación para accionadores neumáticos, que comprende: una fuente de presión neumática; un dispositivo (112) de corte de vitrectomía que presenta un mecanismo de corte, un primer orificio de entrada neumático (212) y un segundo orificio de entrada neumático (214); un accionador (204) neumático configurado para alternar la presión neumática hacia el primer y segundo orificios de entrada neumáticos, basándose en unas señales de funcionamiento recibidas desde un controlador (216); un primer transductor de presión (206) colocado y configurado para medir la presión real (p1) en el primer orificio de entrada neumático (212); un segundo transductor de presión (208) colocado y configurado para detectar la presión real (p0) en el segundo orificio de entrada neumático (214); estando el controlador (216) en comunicación con el primer y segundo transductores de presión (206, 208) y el accionador (204) neumático, estando el controlador configurado para medir un tiempo real (t1), en que la presión real medida (p1) del primer transductor de presión (206) está por encima de un umbral de presión mínimo almacenado (P1), y estando asimismo configurado para cambiar el momento de accionamiento del accionador (204) neumático, basándose en la comparación del tiempo real, en que la presión real medida del primer transductor de presión está por encima del umbral de presión mínimo, con un tiempo deseado (T1), en que se desea que la presión real medida esté por encima del umbral de presión mínimo.
