Abstract

An ophthalmic surgical cassette for use with an ophthalmic surgical console. The ophthalmic surgical cassette includes a rigid-walled container having an interior volume for collecting aspirant fluid and/or tissue, and a manifold base, including an irrigation tube for coupling an irrigation source, an aspiration tube for coupling an ophthalmic surgical handpiece, and an identification feature for indicating a cassette type to an ophthalmic surgical console. The manifold base is removeably attached to the rigid-walled container.

Claims

1. An ophthalmic surgical cassette for use with an ophthalmic surgical console, the ophthalmic surgical cassette comprising:

a rigid-walled container having an interior volume for collecting aspirant fluid and/or tissue;

a manifold base, including an irrigation tube for coupling an irrigation source, an aspiration tube for coupling an ophthalmic surgical handpiece, and an identification feature for indicating a cassette type to an ophthalmic surgical console, the manifold base being removeably attached to the rigid-walled container; and

whereby the ophthalmic surgical console detects the identification feature to enable, based on the cassette type, at least one surgical function.

2. The ophthalmic surgical cassette of claim 1, wherein the identification feature is a refraction element.

3. The ophthalmic surgical cassette of claim 1, wherein the rigid-walled container includes a fluid level indicator for indicating a level of aspirant fluid and/or tissue in the rigid-walled container.

4. The ophthalmic surgical cassette of claim 3, wherein the identification feature is disposed inline with the fluid level indicator, such that a linear detector is capable of detecting the identification feature and the fluid level indicator.

5. The ophthalmic surgical cassette of claim 1, wherein the manifold base includes an auxiliary aspiration tube.

6. An ophthalmic surgical cassette for use with an ophthalmic surgical console, the ophthalmic surgical cassette comprising:

a rigid-walled container having an interior volume for collecting aspirant fluid and/or tissue and a fluid level indicator for refracting light generated by an ophthalmic surgical console to indicate a level of aspirant fluid and/or tissue within the rigid-walled container;

a manifold base removeably attached to the rigid-walled container, the manifold base, including an irrigation tube for coupling an irrigation source, an aspiration tube for coupling an ophthalmic surgical handpiece, and a refraction element for indicating a cassette type to the ophthalmic surgical console, the refraction element being disposed inline with the fluid level indicator; and

whereby the cassette type and the level of aspirant fluid and/or tissue are detectable by a photo-detector included in the ophthalmic surgical console.

7. An ophthalmic surgery pump system for use during an ophthalmic surgery procedure, the ophthalmic surgery pump system comprising:

an ophthalmic surgical cassette including a rigid-walled container and a manifold base removeably attached to the rigid-walled container, the manifold base, including an irrigation tube, an aspiration tube, and an identification feature for indicating a cassette type; and

an ophthalmic surgical console, including a detector disposed adjacent to the ophthalmic surgical cassette for detecting the identification feature and a processor operably coupled to the detector for enabling, based on the cassette type, at least one surgical function.

8. The ophthalmic surgery pump system of claim 7, wherein the identification feature includes a refraction element.

9. The ophthalmic surgery pump system of claim 8, wherein the identification feature includes a prism.

10. The ophthalmic surgery pump system of claim 8, wherein the detector includes a linear CCD array.

11. The ophthalmic surgery pump system of claim 10, wherein the ophthalmic surgical cassette includes a fluid level indicator disposed inline with the identification feature.

12. The ophthalmic surgery pump system of claim 11, wherein the linear CCD array extends adjacent to the identification feature and the fluid level indicator, such that the identification feature and the fluid level indicator are detectable by the linear CCD array.

13. The ophthalmic surgery pump system of claim 8, wherein the processor is configured to disable at least one surgical function of the ophthalmic surgical console based on the cassette type.

14. The ophthalmic surgery pump system of claim 8, wherein the manifold base includes an auxiliary aspiration tube.
