Surgical fluidics cassette supporting multiple pumps
View Patent ↗The present invention is generally directed to improved methods, devices, and systems for controlling surgical fluid flows, particularly during treatment of an eye. In many embodiments, the invention provides a console that interchangeably accepts multiple types of eye treatment cassettes. The cassettes enable one or both of displacement-based or vacuum-based aspiration. The console and the cassette may communicate to establish the functionality of the installed cassette. The multiple types of cassettes may be produced using a common cassette frame and may include a visual indication of functionality.
1. An eye treatment system comprising:
an eye treatment probe;
a console having a cassette receptacle that receives a cassette, and
multiple types of cassettes configured to couple the console with the probe, each type of cassette configured for engagement with the cassette receptacle, wherein a first type of cassette enables only displacement-based aspiration and a second type of cassette enables both displacement-based aspiration and vacuum-based aspiration.
2. The eye treatment system of claim 1 , wherein each console and the received cassette communicate to establish a functionality of the cassette.
3. The eye treatment system of claim 2 , wherein the console detects a functional indicator of each received cassette.
4. The eye treatment system of claim 3 , wherein the functional indicator comprises a holding tank connecting stem that actuates a microswitch or an optical switch within the console.
5. The eye treatment system of claim 1 , wherein the multiple types of cassettes utilize a common cassette frame.
6. The eye treatment system of claim 1 , wherein each type of cassette comprises a visual indicator.
7. The eye treatment system of claim 6 , wherein the visual indicator comprises a holding tank visible through a window of the cassette.
8. The eye treatment system of claim 1 , wherein the console comprises a peristaltic pump, said displacement-based aspiration comprising aspiration induced by the peristaltic pump.
9. The eye treatment system of claim 1 , wherein the console comprises a Venturi pump, said vacuum-based aspiration comprising aspiration induced by the Venturi pump.
10. A surgical console configured to receive multiple types of eye treatment cassettes, comprising:
a cassette receptacle for receiving a cassette, the receptacle configured to interchangeably receive multiple types of eye treatment cassettes, wherein the console operates with a first type of cassette to enable only displacement-based aspiration and with a second type of cassette to enable both displacement-based aspiration and vacuum-based aspiration; and
a controller for controlling both displacement-based aspiration and vacuum-based aspiration.
11. The surgical console of claim 10 , further comprising a detector for ascertaining a functionality of each received cassette.
12. The surgical console of claim 11 , wherein the detector comprises a microswitch.
13. A method for using a surgical console with multiple types of eye treatment cassettes, comprising:
interchangeably receiving the multiple types of eye treatment cassettes in a cassette receptacle of the console;
enabling only displacement-based aspiration when a first type of cassette is received and enabling both displacement-based aspiration and vacuum-based aspiration when a second type of cassette is received; and
controlling both the displacement-based aspiration and the vacuum-based aspiration.
14. The method of claim 13 , further comprising detecting a functionality of each received cassette.
15. Eye treatment cassettes of multiple types configured to interchangeably couple with the same surgical console, wherein a first type of cassette enables only displacement-based aspiration when coupled with the console and a second type of cassette enables both displacement-based aspiration and vacuum-based aspiration when coupled with the console.
16. The cassettes of claim 15 , wherein each type of cassette comprises a common functional indicator that communicates with the console to indicate a function of the type of cassette.
17. The cassettes of claim 15 , wherein the multiple types of cassettes all utilize a common cassette frame.
18. The cassettes of claim 15 , wherein each type of cassette comprises a common visual indicator that indicates the type of cassette.
19. The cassettes of claim 15 , wherein the second type of cassette comprises a separably coupled holding tank.
20. The cassettes of claim 19 wherein the holding tank communicates to the console that vacuum-based aspiration is available when the second type of cassette is coupled with the console.
