Abstract:
PROBLEM TO BE SOLVED: To provide the up-and-down grip of a surgical cassette. SOLUTION: One preferred embodiment includes the surgical cassette having the first side (for example, the inside) and the second side (for example, the outside) which can be employed for a surgical system. The surgical cassette includes a main body of composition of forming interface in a surgical console on the first side at during the use, the first gripper which projects from the upper part of the main body composed so as to touch the first clamp rail on the second side during the use, and the second gripper which projects from the lower part of the main body composed so as to touch the second clamp rail on the second side during the use.

Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and method for controlling the flow of aspiration fluid in an aspiration chamber of a surgical cassette. SOLUTION: The aspiration chamber having an aspiration port 632 positioned at or close to the bottom of an aspiration chamber 624 is provided. When the aspiration fluid enters the aspiration chamber from below the fluid surface (e.g., from a port located at the bottom or on a sidewall close to the bottom), it does not create disturbance at the liquid/air interface and thus does not disturb continuous level sensing. Also, since the aspiration port is placed at or very close to the bottom of the aspiration chamber, the liquid inside the chamber can be fully used for sustained reflux and push priming.

Abstract:
A microsurgical system capable of controlling aspiration and detecting an occlusion via monitoring a change in either suction flow rate or suction impedance.
Abstract:
Aparato para controlar la aspiración en un sistema microquirúrgico (10), que comprende: una fuente de gas presurizado (12); un generador de vacío (22) acoplado de manera fluida a dicha fuente de gas presurizado (12); una cámara de aspiración (26) acoplada de manera fluida a dicha fuente de gas presurizado (12) y a dicho generador de vacío (22); un sensor de nivel de fluido (28) acoplado de manera funcional a dicha cámara de aspiración (26); una bomba (30) acoplada de manera fluida a dicha cámara de aspiración (26); un controlador proporcional (40); y un ordenador (38) eléctricamente acoplado a dicho sensor de nivel de fluido (28), dicha bomba (30) y dicho controlador proporcional (40); en el que, tras la selección de un caudal de succión deseado para dicha cámara de aspiración a través de dicho controlador proporcional, dicho sensor de nivel de fluido (28) determina un nivel de fluido real en dicha cámara de aspiración (26) y proporciona una señal correspondiente a dicho nivel de fluido determinado a dicho ordenador (38), y dicho ordenador (38) calcula un caudal de succión en respuesta a dicho nivel de fluido determinado y utiliza dicho caudal de succión calculado para detectar una oclusión.
Abstract:
Embodiments of the present invention provide an apparatus for controlling the flow of aspiration fluid in an aspiration chamber (185,524,624) of a surgical cassette (150,522,600). One embodiment of the present invention provides an aspiration chamber having an aspiration port (632) positioned at or close to the bottom of the chamber. When the aspiration fluid enters the aspiration chamber from below the fluid surface (e.g., from a port located at the bottom or on a sidewall close to the bottom), it does not create disturbance at the liquid/air interface and thus does not disturb continuous level sensing. Also, since the aspiration port is placed at or very close to the bottom of the aspiration chamber, the liquid inside the chamber can be fully used for sustained reflux and push priming.
Abstract:
Modalidades de la presente invención proporcionan una sujeción superior e inferior de un cassette quirúrgico. Una modalidad de la presente invención incluye un cassette quirúrgico adaptado para su uso en un sistema quirúrgico que tiene un primer lado (por ejemplo, un lado interno) y un segundo lado (por ejemplo un lado externo). El cassette quirúrgico, de conformidad con una modalidad, comprende una porción de cuerpo configurada para conexión en su primer lado con una consola quirúrgica durante el uso, una primera porción de sujeción que se proyecta a partir de la parte superior de la porción de cuerpo configurada para entrar en contacto con un primero riel de sujeción en el segundo lado del cassette durante el uso y una segunda porción de sujeción que se proyecta a partir del fondo de la porción de cuerpo configurada para entrar en contacto con un segundo riel de sujeción en el segundo lado del cassette durante el uso.
