Abstract

Devices, systems, and methods including a lubricating solution bath for a pump integrated into an ophthalmic surgical hand piece are provided. In some embodiments, an ophthalmic pump system includes a housing defining a cavity. The system includes a rotating element positioned within the cavity of the housing. The system includes a flexible tubular structure positioned within the housing adjacent to the rotating element such that rotation of the rotation element urges a fluid through the flexible tubular structure. The system includes a lubricating solution positioned within the cavity around the rotating element and at least a portion of the flexible tubular structure.

Claims

1. An ophthalmic pump system, comprising:

a housing defining a cavity;

a rotating element positioned within the cavity of the housing;

a plurality of flexible tubular components positioned within the housing adjacent to the rotating element such that rotation of the rotating element urges a fluid through the plurality of flexible tubular components; and

a lubricating solution positioned within the cavity around the rotating element and at least a portion of the plurality of flexible tubular components,

wherein the rotating element is simultaneously in contact with more than one of the plurality of flexible tubular components,

wherein the plurality of flexible tubular components includes a first tubular element and a second tubular element, the first and the second tubular elements being disposed around the housing, and

further comprising a channel extending annularly around the housing, the channel being in fluid communication with the first and the second tubular elements.

2. The ophthalmic pump system of claim 1, wherein the lubricating solution comprises at least one of:

balanced salt solution (BSS), balanced salt solution plus (BSS+), a viscoelastic solution, and sterile water.

3. The ophthalmic pump system of claim 1, wherein at least a portion of the flexible tubular components extends along a longitudinal axis of the housing.

4. The ophthalmic pump system of claim 1, wherein the plurality of flexible tubular components includes a central tubular element disposed at a distal portion of the housing, the central tubular element being in fluid communication with the first and the second tubular elements.

5. The ophthalmic pump system of claim 1, further comprising a projection extending from the housing, the projection including a lumen in fluid communication with the channel.

6. The ophthalmic pump system of claim 1, wherein the housing is mechanically coupled to a surgical component such that the flexible tubular components are in fluid communication with a lumen of the surgical component.

7. The ophthalmic pump system of claim 6, wherein the surgical component is a phacoemulsification component.

8. The ophthalmic pump system of claim 1, wherein the rotating element is a scroll pump.

9. The ophthalmic pump system of claim 8, wherein the scroll pump is disposed in a pump component mechanically coupled to the housing.

10. An ophthalmic lubrication kit for use with an ophthalmic surgical device, the kit comprising:

a housing defining a cavity, the cavity configured to be filled with a lubricating solution and receive a rotating element, the housing including a plurality of flexible tubular components positioned in an interior thereof and configured to be adjacent the rotating element when the rotating element is received in the housing such that rotation of the rotating element urges a fluid through the plurality of flexible tubular components; and

a container of the lubricating solution,

wherein the plurality of components are at least partially positioned adjacent to the rotating element such that the rotating element is simultaneously in contact with more than one of the plurality of components,

wherein the flexible tubular components include a first tubular element and a second tubular element, the first and the second tubular elements being disposed around the housing, and

wherein the housing further comprises;

a channel extending annularly around the housing, the channel being in fluid communication with the first and the second tubular elements.

11. The ophthalmic lubrication kit of claim 10, wherein the lubricating solution comprises at least one of:

balanced salt solution (BSS), balanced salt solution plus (BSS+), a viscoelastic solution, and sterile water.

12. The ophthalmic lubrication kit of claim 10, wherein the housing further comprises:

a projection extending from the housing, the projection including a lumen in fluid communication with the channel.

13. The ophthalmic lubrication kit of claim 10, wherein the housing is configured to be mechanically coupled to a surgical component such that the flexible tubular components are in fluid communication with the surgical component.
