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.

Claims

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, the roller engaged with the deformable conduit to cause the deformable tubing 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 material within the conduit lumen therealong.

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 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.

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

5. The system of claim 3, wherein the roller driver comprises a groove sized and shaped to accommodate the plurality of rollers.

6. The system of claim 3, 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.

7. The system of claim 6, 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.

8. The system of claim 7, 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.

9. The system of claim 3, 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.

10. 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.

11. The system of claim 10, wherein the motor rotates the roller driver.

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

13. 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.

14. 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 an eye, the tip including a tip lumen arranged to carry fluid;

a peristaltic pump disposed within the housing, the peristaltic pump comprising;

a deformable conduit defining a conduit lumen, the conduit lumen in fluid communication with the tip lumen;

a plurality of rollers in contact with the deformable conduit, the plurality of rollers forming localized deformations in the deformable conduit, each of the plurality of rollers comprising an outer peripheral surface; and

a roller driver in contact with the outer peripheral surface of each roller of the plurality of rollers, the plurality of rollers movable in response to movement of the roller driver to transport material within the conduit lumen therealong; and

a motor disposed within the housing, the motor comprising a motor shaft coupled to the roller driver, the roller driver movable in response movement of the motor shaft.

15. The system of claim 14, further comprising a controller operable to transmit a control signal to the motor to increase and decrease a speed of the motor.

16. The system of claim 14, further comprising a drain reservoir in fluid communication with the deformable conduit, wherein material transported within the conduit lumen is deposited in the drain reservoir.

17. The system of claim 14, wherein the handheld probe comprises a phacoemulsification probe.

18. An ophthalmic surgical method, comprising:

inserting a tip of a surgical probe into an eye of a patient, the tip including an aspiration lumen arranged to carry material away from the eye;

contacting a plurality of rollers with a deformable conduit to cause localized deformation of the deformable conduit by each of the plurality of rollers;

engaging an outer peripheral surface of each of the plurality of rollers by a roller driver; and

aspirating material from the eye by moving the roller driver to cause movement of the plurality of rollers along the deformable conduit to peristaltically pump material contained within a lumen of the deformable conduit.

19. The method of claim 18, wherein the roller driver is coupled to a motor disposed within the surgical probe, and

wherein the motor comprises motor shaft coupled to the roller driver.

20. The method of claim 18, further comprising:

disposing the deformable conduit within a channel formed in a track housing; and

moving the plurality of rollers along a track formed by the channel.
