Abstract

Claims (43)

1 . A surgical system, comprising:

a console;

a handpiece; and

a cassette that couples the handpiece with the console,

the cassette comprising a front plate and a fluid manifold,

wherein the front plate comprises one or more outer border faces that form an axial mating plane surface for mating with the console;

wherein the front plate comprises one or more raised surfaces for coupling with an engagement mechanism of the console,

wherein, when the one or more raised surfaces are coupled with the engagement mechanism of the console, the axial mating plane surface is compressed parallel to a mounting reference surface of the console;

wherein the front plate includes a drain port,

wherein the front plate is reusable,

wherein the fluid manifold comprises a first half, a second half, and an overmolded seal that permanently bonds the first half and the second half, wherein the permanently bonded first half and second half form a plurality of fluid pathways that are integral to the first half and the second half of the fluid manifold,

wherein the first half and the second half are formed from at least a first material and the overmolded seal is formed from a second material,

wherein the fluid manifold and the front plate are configured to be removable from at least a portion of the cassette, wherein at least a portion of the plurality of fluid pathways are configured to transmit fluid aspirated from the handpiece to the drain port, and

wherein the drain port comprises an opening for transmitting the fluid from inside of the cassette to an external collection reservoir.

2 . The system of claim 1 , wherein the front plate is die cast from aluminum.

3 . The system of claim 1 , wherein the front plate is molded from a durable plastic.

4 . The system of claim 1 , wherein the fluid manifold comprises tube set orifices that are augmented by barb fittings.

5 . The system of claim 4 , wherein the tube set orifices are configured to couple with a tube.

6 . The system of claim 5 , wherein the tube is a peristaltic pump tube.

7 . The system of claim 5 , wherein the tube set orifices constrain the tube to prevent axial or torsional movement of the tube.

8 . A cassette suitable for coupling a handpiece with a console in a surgical system, the cassette comprising:

a front plate that includes a drain port and one or more outer border faces that form an axial mating surface for mating with the console, wherein the front plate comprises one or more raised surfaces for coupling with an engagement mechanism of the console, wherein, when the one or more raised surfaces are coupled with the engagement mechanism of the console, the axial mating plane surface is compressed parallel to a mounting reference surface of the console; and

a fluid manifold having a first half, a second half, and an overmolded seal that permanently bonds the first half and the second half, wherein the permanently bonded first half and second half form a plurality of fluid pathways that are integral to the first half and the second half of the fluid manifold,

wherein the first half and the second half are formed from at least a first material and the overmolded seal is formed from a second material,

wherein the fluid manifold and the front plate are configured to be removable from at least a portion of the cassette,

wherein at least a portion of the plurality of fluid pathways are configured to transmit fluid aspirated from the handpiece through the fluid manifold; and

wherein the drain port comprises an opening for transmitting the fluid from inside of the cassette to an external collection reservoir.

9 . The cassette of claim 8 , further comprising an external collection reservoir removably coupled to at least the front plate, the external collection reservoir configured to collect the aspirated fluid.

10 . The cassette of claim 9 , wherein the external collection reservoir comprises a drain bag assembly, and wherein the at least the portion of the plurality of fluid pathways are configured to transmit fluid aspirated from the handpiece to the drain bag assembly.

11 . The cassette of claim 8 , wherein the first half and the second half are bonded together using ultrasonic welding.

12 . The cassette of claim 8 , wherein the plurality of fluid pathways comprise raised surfaces in relation to a cross-sectional plane through the fluid manifold.

13 . The cassette of claim 8 , wherein one or more of the plurality of fluid pathways comprise an irrigation flow channel.

14 . The cassette of claim 8 , wherein one or more of the plurality of fluid pathways comprise an aspiration flow channel.

15 . The cassette of claim 8 , wherein one or more of the plurality of fluid pathways comprise a vent flow channel.

16 . The cassette of claim 8 , wherein the front plate is formed by die casting.

17 . The cassette of claim 8 , wherein the front plate is formed from a durable plastic.

18 . The cassette of claim 8 , wherein the fluid manifold further comprises tube set orifices configured to couple with a tube.

19 . The system of claim 1 , wherein the one or more raised surfaces are one clamping domes configured to engage respectively with one or more rotary clamps of the console.

20 . The system of claim 1 , further comprising a back plate and a tube,

wherein the front plate and the back plate form a backing plate pump profile that compresses the tube against one or more peristaltic pump rollers of the console when the cassette engages the console.

21 . The cassette of claim 8 , wherein the one or more raised surfaces are one clamping domes configured to engage respectively with one or more rotary clamps of the console.

22 . The cassette of claim 8 , further comprising a back plate and a tube,

wherein the front plate and the back plate form a backing plate pump profile that compresses the tube against one or more peristaltic pump rollers of the console when the cassette engages the console.
