Abstract

A cassette latching mechanism generally including an articulating clamp mounted on the end of a pneumatic cylinder. The clamp interacts with a slot, tab or tang on the cassette housing to hold the cassette firmly within a surgical console.

Claims

1. An apparatus for latching a surgical cassette within a surgical console, comprising:

a) an extendable cylinder mounted to the surgical console; and

b) an articulating clamp having at least one prong, the clamp pivotally mounted to the cylinder and sufficiently close to the cassette so that the prong interacts with at least one clamping face on the surgical cassette when the cassette is inserted in the console so as to hold the cassette within the console.

2. The apparatus of claim 1 further comprising a fluid passage in the clamp.

3. The apparatus of claim 1 wherein the clamp has a flange and is mounted to the cylinder by a pin.

4. The apparatus of claim 1 wherein the clamp articulates about a pin held within a recess in the surgical console.

5. The apparatus of claim 1 wherein the cylinder comprises a pneumatic cylinder.

6. The apparatus of claim 1 wherein the cylinder comprises a hydraulic cylinder.

7. An apparatus for latching a surgical cassette within a surgical console, comprising:

a) an extendable cylinder mounted to the surgical console; and

b) an articulating clamp having a flange, a fluid passage and a plurality of prongs, the clamp pivotally mounted to the cylinder by a pin and located sufficiently close to the cassette when the cassette is inserted in the console so as to hold the cassette within the console.

8. The apparatus of claim 7 wherein the clamp articulates about a pin held within a recess in the surgical console.

9. The apparatus of claim 7 wherein the prongs cooperate with clamping faces on the surgical cassette.

10. The apparatus of claim 7 wherein the cylinder comprises a pneumatic cylinder.

11. The apparatus of claim 7 wherein the cylinder comprises a hydraulic cylinder.

12. An apparatus for latching a surgical cassette within a surgical console, comprising:

a) an extendable cylinder mounted to the surgical console; and

b) an articulating clamp having a plurality of prongs, the clamp pivotally mounted to the cylinder and sufficiently close to the cassette so that the prongs interact with a plurality of clamping faces on the surgical cassette when the cassette is inserted into the console and hold the cassette within the console.

13. The apparatus of claim 12 wherein the cylinder comprises a pneumatic cylinder.

14. The apparatus of claim 12 wherein the cylinder comprises a hydraulic cylinder.

15. The apparatus of claim 12 wherein the clamp has a flange and is mounted to the cylinder by a pin.

16. The apparatus of claim 12 further comprising a fluid passage in the clamp.
