Abstract
A surgical system includes a replaceable surgical cassette that is configured to be received by a surgical console, the surgical cassette permitting fluid flow through the cassette, the surgical system controlling the flow of fluid through the cassette via one or more flexible valves actuated by one or more actuation plungers located on the surgical console. The one or more flexible valves of the surgical cassette and the one or more actuation plungers of the surgical console include a positioning feature configured to assist with positioning the one or more actuation plungers to apply uniform and symmetric pressure to the one or more valves during actuation.
Claims20
A surgical system, comprising:
- a console, the console including one or more moveable plungers:
- a cassette, the cassette including a front plate and a gasket formed with one or more deformable valves, the one or more valves configured to generally align with the one or more moveable plungers when the cassette is connected to the console;
- and
- a positioning feature, the positioning feature including:
- spaced-apart teeth, including a first tooth and a second tooth, coupled with a back surface of the one or more valves and extending axially away from the back surface, the spaced-apart teeth forming a locking recess, wherein the first tooth includes a first receiving surface and the second tooth includes a second receiving surface, wherein the first receiving surface is spaced a distance from the second receiving surface, and wherein the first receiving surface includes a first angled portion and a second angled portion, the first angled portion extending from a bottom circumference surface of the spaced-apart teeth to generally a center axis of the locking recess and the second angled portion extending from a top circumference surface of the spaced-apart teeth to generally the center axis of the locking recess, the first angled portion extending at a first angle from a first axis along the locking recess and the second angled portion extending at a second angle from the first axis, the second angle being different from the first angle;
- and
- a blade tooth coupled with the one or more moveable plungers, the blade tooth dimensioned similar to the dimension of the locking recess to be received within the locking recess, and wherein the blade tooth further includes an end cap including at least one tapered side configured to align with at least one tapered surface of the locking recess.
