DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As best seen in FIGS. 1, 2 and 3, cassette 10 that may be used with the present invention generally included valve plate 12, body 14 and cover 16. Valve plate 12, body 14 and cover 16 may all be formed of a suitable, relatively rigid, and thermoplastic. Valve plate 12 contains a plurality of openings 18 and pumping channel 20 that are sealed fluid tight by elastomers 22 and 24, forming a plurality of fluid paths. Ports 26 provide connectors between cassette 10 and surgical console 100 for the various irrigation and aspiration (pneumatic) functions of cassette 10 when cassette 10 is installed in cassette receiving portion 110 of console 100.


As best seen in FIG. 4, fluidics manifold 200 contains a plurality of sub-assemblies or manifolds mounted to common primary manifold 210. For example, fluidics manifold 200 may additionally contain aspiration manifold 220, and/or infusion/irrigation manifold 230 and/or valve or pincher manifold 240. As seen in FIG. 5, for example, each of manifolds 210, 220, 230 and 240 (manifold 240 used as an illustrative example) are self-contained, and may contain necessary the valves, regulators, sensors or other active embedded mechanical, electrical or electromechanical devices required to perform each manifold's primary function, such as air cylinders 245, by way of example. Manifolds 220 and 230 pneumatically and fluidly communicate with cassette 10 through primary manifold 210, such communication being controlled by pincher manifold 240. Primary manifold 210 may be mounted in cassette receiving portion 110 of console 100 so that cassette 10 may be fluidly coupled to primary manifold 210. Primary manifold 210 may additionally contain pumps and fluid level and/or fluid flow sensors (all not shown).


Such a construction allows for the separation of the primary functionalities of each sub-assembly onto specific manifolds, thereby providing convenient and fast assembly, troubleshooting and repair. In addition, such a construction eliminates the various tubings and tubing connectors used in the prior art to connect the various components in each sub-assembly and reduces the overall size of the completed assembly.


This description is given for purposes of illustration and explanation. It will be apparent to those skilled in the relevant art that modifications may be made to the invention as herein described without departing from its scope or spirit.
