Abstract: A fluidic cassette detection mechanism is used for detecting the presence of a cassette (12) at a certain position within a fluidic module (10). When the cassette is inserted into the fluidic module to a certain position and orientation, the detector mechanism senses the presence of the fluidic cassette and provides an appropriate signal to the control system (28) software. The system software can then command the closing of a clamping mechanism which holds the cassette during a procedure. The fluidic cassette detector mechanism can comprise a number of mechanical probes (22), optical interrupt switches (24), and miscellaneous components including springs and screws. The probes (22) extend beyond the face of the fluidic module (10) faceplate and beyond the rear stops of the clamps. When the fluidic cassette is inserted into the fluidic module (10) far enough to sufficiently move the probes, the probes trip the switches (24) to signal that the cassette is in the correct position and orientation for the clamping motion to begin. The correct position and orientation are sensed due to the use of the probes (22) in the mechanism. The probes are spaced sufficiently apart on a diagonal, and raised beyond the rear stops of the cassette clamps, such that when both probes are moved appropriately, the cassette must be acceptably parallel to the clamps, and in the correct position, for the cassette clamping motion to begin.

Abstract: Embodiments of the present invention provide top and bottom clamping of a surgical cassette (150). One embodiment of the present invention includes a surgical cassette adapted for use in a surgical system having a first side (170) (e.g., an inner side) and second side (180) (e.g., an outer side). The surgical cassette, according to one embodiment, comprises a body portion (155,205) configured to interface on its first side with a surgical console (100) during use, a first clamping portion (195) projecting from the top of the body portion configured to contact a first clamp rail (182) on the cassette's second side during use and a second clamping portion (190) projecting from the bottom of the body portion configured to contact a second clamp rail (142) on the cassette's second side during use.

Abstract: A continuous high resolution fluid level monitoring system (300) is provided by embodiments of the present invention. This continuous high resolution fluid level monitoring system includes a unique fluid level sensor having a point light source (202), parabolic reflector (204), sensor array (308), and detection, processing and control system (310). The point light source illumines a parabolic reflector wherein the point light source is located at the focus of the parabolic reflector. The parabolic reflector reflects light from the point light source to produce a parallel light curtain (210). This parallel light curtain is parallel to an axis of symmetry of the parabolic reflector. The parallel light curtain illumines a chamber (302) such as a chamber in an ophthalmic surgical device used to contain surgical fluid (304). The sensor array coupled to the chamber detects the parallel light curtain illuminating the chamber. The sensor array provides an output to a detection/processing/control system in order to determine the fluid level within the chamber. This optical method of determining the surgical fluid levels may be advantageous in that it prevents physical contamination of the surgical fluids.

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.

Abstract: Se utiliza un mecanismo de detección de cassette de fluidos para detectar la presencia de un cassette en una cierta posición dentro de un módulo de fluidos. Cuando el cassette se inserta hacia el módulo de fluidos a una cierta posición y orientación, el mecanismo detector percibe la presencia del cassette de fluidos y proporciona una señal apropiada al software del sistema. El software del sistema puede entonces ordenar el cierre del mecanismo, que retiene el cassette durante un procedimiento. E l mecanismo detector de cassette de fluidos puede comprender un número de sondas mecánicas, conmutadores de interrupción óptica, y diversos componentes incluyendo resortes y tornillos . Las sondas se extienden más allá de la cara de la placa de cara de módulo de fluidos y más allá de los topes posteriores de las abrazaderas, Cuando el cassette de fluidos se inserta hacia el módulo de fluidos lo bastante lejos para mover suficientemente las sondas, las sondas disparan los conmutadores para señalar que el cassette está en la posición y orientación correcta para que empiece el movimiento de sujeción. La posición y orientación correctas se perciben debido al uso de sondas en el mecanismo. Las sondas están suficientemente espaciadas en una diagonal, y levantadas más allá de los topes posteriores de las abrazaderas de cassette, tal como cuando mas sondas se mueven apropiadamente, el cassette debe estar aceptablemente paralelo a las abrazaderas, y en la posición correcta, para que empiece el movimiento de sujeción de cassette.

Abstract: A surgical cassette (150) is provided which is adapted for insertion into a cassette receiver (125) in a surgical console (100) and to be held in place by at least one clamp (144,184) in the cassette receiver, the cassette comprising compliant clamping zones (160,190; 165,195) configured to deform to conform to any non-uniform load profile applied to the cassette. The clamping portion(s) (190,195) can include ribs (240) that are sized and made of a suitable material such that the ribs will deflect predictably in an elastic region and flow plastically when the material yield point is exceeded. The use of ribs creates discrete small load areas that will deflect and distort predictably and non-catastrophically at high loads. This allows for the absorption of accumulated tolerances between the clamping mechanism (142,144; 182,184) and the cassette (e.g. non-parallelism between the clamping mechanism and the cassette while still providing a distributed load on the cassette.

Abstract: A system (100) and computer-implemented method are provided for allowing a user to select the release modality of a surgical cassette (150) so as to control a cassette release mechanism (142,144,182,184). Examples of release modes include an immediate, instant or latching mode, a continuous mode or a delay mode. A user interface (115) can be provided that allows a user to select (250) a cassette release mode for a surgical cassette from a set of cassette release modes, determining that a release request is asserted, and issuing one or more commands (260,265,295) to cause the surgical cassette to be released from a cassette receiver (125) according to the selected cassette release mode. The user can also select whether the release command can be asserted through a release button (145) or the user interface (115).
