Abstract
A system and method for detecting and/or capturing a cassette is disclosed. The cassette capture mechanism may be used with a surgical console of a surgical system, wherein the system has a cassette receiving area having at least two alignment sensors and a plurality of capture plungers; and at least two capture hooks which may engage with a cassette, wherein at least one of the at least two alignment sensors produces a signal indicative of the presence of a cassette.
Claims19
A system for phacoemulsification surgery, comprising:
- a cassette receiving area for receiving a cassette having a sidewall shaped to at least partially surround an outer surface of the cassette, the cassette receiving area comprising at least two alignment sensors and a plurality of capture plungers, wherein each capture plunger is positioned within an opening in the sidewall and has a tip that protrudes through the sidewall, and wherein the tip is positioned below the outer surface of the cassette when the cassette is seated in the cassette receiving area;
- and
- at least two capture hooks which are configured to engage with the cassette,
- wherein each of the at least two alignment sensors comprise two transceivers configured to collectively produce a first signal indicative of the cassette in a preloaded condition and a second signal indicative of the cassette in a loaded condition.
A method for seating a surgical cassette in a phacoemulsification surgery console, the method comprising:
- providing a cassette receiving area comprising at least two alignment sensors, the receiving area having a sidewall shaped to at least partially surround an outer surface of the surgical cassette;
- providing a plurality of capture plungers, wherein each capture plunger is positioned within an opening in the sidewall and has a tip that protrudes through the sidewall, and wherein the tip is positioned below the outer surface of the surgical cassette when the surgical cassette is seated in the cassette receiving area;
- and
- providing at least two capture hooks which are configured to engage with the surgical cassette, wherein each of the at least two alignment sensors comprise two transceivers configured to collectively produce a first signal indicative of the surgical cassette in a preloaded condition and a second signal indicative of the surgical cassette in a loaded condition.
An apparatus for receiving a surgical cassette having an outer surface, comprising:
- a cassette receiving area for receiving the surgical cassette, the cassette receiving area having a sidewall shaped to at least partially surround an outer surface of the surgical cassette, the cassette receiving area comprising at least two alignment sensors;
- a plurality of capture plungers, wherein each capture plunger is positioned within an opening in the sidewall and has a tip that protrudes through the sidewall, and wherein the tip is positioned below the outer surface of the surgical cassette when the surgical cassette is seated in the cassette receiving area;
- and
- at least two capture hooks, wherein the at least two capture hooks are configured to securely engage in the surgical cassette,
- wherein each of the at least two alignment sensors comprise two transceivers configured to collectively produce a first signal indicative of the surgical cassette in a preloaded condition and a second signal indicative of the surgical cassette in a loaded condition.
