Abstract

A surgical cassette for use with a phacoemulsification system having a front plate, a back plate, and a gasket therebetween. The front plate having molded fluid channels that mate with the gasket. The gasket having multiple valves and a sensor or diaphragm accessible through the back plate.

Claims

1. A surgical cassette, comprising:

a front plate;

a back plate; and

a gasket including at least one raised lip portion that is arranged for placement adjacent at least one fluid channel to seal off at least a portion of the at least one fluid channel,

wherein at least a portion of the gasket is located between the front plate and the back plate,

wherein the gasket comprises one or more valves and a sensor, and

wherein the one or more valves and the sensor are accessible through the back plate.

2. The surgical cassette of claim 1, further comprising one or more tube retainers configured and dimensioned to guide a portion of a tube into a desired shape.

3. The surgical cassette of claim 2, wherein the desired shape is capable of being used with a peristaltic pump.

4. The surgical cassette of claim 2, wherein the tube retainers constrain the tube to prevent axial or torsional movement of the tube.

5. The surgical cassette of claim 2, the front plate having a surface, wherein the surface comprises one or more raised surfaces having a substantially circular shape, wherein the one or more raised surfaces are configured and dimensioned to provide at least one high point when coupled with an engagement mechanism.

6. The surgical cassette of claim 5, wherein the one or more raised surfaces are located along a least a portion of a peripheral edge of the surface of the front plate.

7. A surgical system, comprising:

a console;

a handpiece; and

a cassette;

wherein the cassette couples the handpiece with the console,

wherein the cassette comprises a front plate, a back plate, and a gasket,

wherein at least a portion of the gasket is located between the front plate and the back plate,

wherein the gasket comprises one or more valves and a sensor, and

wherein the one or more valves and the sensor are accessible through the back plate.

8. The surgical system of claim 7, further comprising one or more tube retainers configured and dimensioned to guide a portion of a tube into a desired shape.

9. The surgical system of claim 8, wherein the desired shape is substantially c-shaped.

10. The surgical system of claim 8, wherein the desired shape is capable of being used with a peristaltic pump.

11. The surgical system of claim 8, wherein the tube retainers constrain the tube to prevent axial or torsional movement of the tube.

12. The surgical system of claim 7, wherein the console comprises an engagement mechanism and the cassette further comprises a surface, wherein the surface comprises one or more raised surfaces having a substantially circular shape, wherein the one or more raised surfaces are configured and dimensioned to provide at least one high point for coupling with the engagement mechanism.

13. The surgical system of claim 12, wherein the surface is located on the front plate.

14. The surgical system of claim 12, wherein the engagement mechanism is selected from the group consisting of a position mechanism and a clamping mechanism.

15. The surgical system of claim 14, where the position mechanism is selected from the group consisting of a linear actuator, a rotary actuator, and a magnetic coupling.

16. The surgical system of claim 14, wherein the clamping mechanism is selected from the group consisting of an electrical actuator, a hydraulic actuator, and pneumatic actuator.
