Abstract

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An ophthalmic surgical system may include a handheld probe. The probe may include a housing sized and shaped for grasping by a user. The probe may include a tip extending from the housing and being sized to penetrate and treat an eye of a patient. The tip may include an aspiration lumen arranged to carry fluid away from the eye. The probe may include a peristaltic pump disposed within the housing. The pump may include a roller in contact with a deformable conduit in fluid communication with the aspiration lumen. The roller may be arranged to deform the conduit while in contact therewith. The pump may also include a roller driver in contact with a periphery of the roller in a manner that moves the roller along the conduit to urge the fluid through the conduit.

First claim

What is claimed is:

1. An ophthalmic surgical system comprising:
a handheld probe comprising:
a housing sized and shaped for grasping by a user;
a tip extending from the housing and being sized to penetrate and treat an eye of a patient, the tip including an aspiration lumen arranged to carry material away from the eye; and
a peristaltic pump disposed within the housing, the peristaltic pump comprising:
a deformable conduit comprising a conduit lumen extending therethrough, the conduit lumen in fluid communication with the aspiration lumen;
a roller in contact with the deformable conduit and comprising an outer peripheral surface forming a majority of an outer surface area of the roller, the roller engaged with the deformable conduit to cause the deformable conduit to deform; and
a roller driver in contact with the outer peripheral surface of the roller, the roller movable along the deformable conduit in response to movement of the roller driver to cause movement of the material within the conduit lumen therealong;
wherein the peristaltic pump comprises a plurality of rollers arranged in a circular configuration, and wherein the plurality of rollers are in contact with the deformable conduit and disposed between the deformable conduit and the roller driver;
wherein the roller driver comprises a groove sized and shaped to accommodate the plurality of rollers.

2. The system of claim 1 , wherein the roller driver does not include an axle extending through the roller.

3. The system of claim 1 , wherein the roller driver comprises a surface in contact with the plurality of rollers.

4. The system of claim 1 , wherein the peristaltic pump further comprises a track housing defining a channel, wherein the channel defines a track along which the plurality of rollers travels.

5. The system of claim 4 , wherein the deformable conduit is positioned within the channel, and wherein the plurality of rollers are arranged to move along the track while in contact with the deformable conduit and the roller driver.

6. The system of claim 5 , wherein the track comprises a contact surface that limits deformation of the deformable conduit by limiting movement of the plurality of rollers into the channel.

7. The system of claim 1 , wherein the peristaltic pump further comprises a guide member having a plurality of recesses, each of the plurality of rollers positioned in a respective one of the plurality of recesses.

8. The system of claim 1 , wherein the probe further comprises a motor disposed within the housing, the motor having a motor shaft coupled to the roller driver.

9. The system of claim 8 , wherein the motor rotates the roller driver.

10. The system of claim 1 , wherein the roller is spherical.

11. The system of claim 1 , wherein the deformable conduit comprises a first segment carrying the material in a first direction and a second segment carrying the material in a second direction.
