Abstract
A surgical cassette for use with a phacoemulsification system having a front housing; and a fluid manifold having an at least partially unibody construction and being removably coupled to at least the front housing. The fluid manifold having molded fluid channels. A surgical system, having a console, a handpiece, and a cassette that couples the handpiece with the console, wherein the cassette has a front housing, a fluid manifold and a drain bag assembly; wherein the fluid manifold has a unibody construction and is removably coupled to at least the front housing and drain bag assembly.
Claims22
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.
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.
