Abstract

Systems, apparatuses, and methods of and for an ophthalmic surgical system are disclosed. An example ophthalmic surgical system may include a body sized and shaped for grasping by a user. The body may include a lumen and a vent in fluid communication with the lumen. The vent may be located and arranged to be selectively occluded, such as when a user places a finger over the vent, and selectively unoccluded, such as when the user removes the finger from over the vent. Fluid pressure within the lumen may be increased when the vent is occluded and decreased when the vent is unoccluded. A piston within the may be displaced in response to the fluid pressure changes within the lumen.

First claim

What is claimed is:

1. An ophthalmic surgical system, comprising:
a body;
a lumen formed in the body and configured to receive a pressurized fluid;
a vent providing fluid communication between the lumen and an exterior the body, the vent adapted to be selectively occluded to alter a pressure condition within the lumen between a pressurized condition and a nonpressurized condition;
a piston moveable to an actuated position in response to the pressurized condition and to an unactuated position in response to the nonpressurized condition; and
a first adjustment component configured to selectively increase and decrease a rate at which the piston moves to an actuated position,
wherein the first adjustment component is a threaded component received into a threaded bore formed in the body, the first adjustment component movable in a direction perpendicular to a longitudinal axis of the body to selectively increase and decrease a rate at which is fluid pressure builds up within the body.

2. The system of claim 1 , further comprising a biasing component disposed within the body, the biasing component configured to bias the piston to the unactuated position.

3. The system of claim 1 , further comprising a second adjustment component configured to selectively increase and decrease a rate at which the piston is returned to an unactuated position.

4. The system of claim 3 , wherein the second adjustment component is a threaded component received into a threaded bore formed in the body, the second adjustment component moveable within a chamber adjacent to the piston to selectively increase and decrease a rate at which fluid pressure within the chamber is relieved.

5. The system of claim 1 , further comprising a nozzle configured to be coupled to a fluid source.

6. The system of claim 1 , wherein the body has a substantially constant outer cylindrical shape.

7. The system of claim 1 , wherein the body comprises a plurality of sections, wherein the plurality of sections have different sizes.

8. The system of claim 1 , further comprising a connector disposed at a distal portion of the body, wherein the connector is configured to interface with a removable instrument tip.

9. An ophthalmic surgical system, comprising:
a fluid source;
an ophthalmic device handle comprising:
a body;
a lumen formed in the body and in fluid communication with the fluid source;
a vent formed in the body and providing fluid communication between the lumen and the exterior of the body, the vent adapted to be selectively occluded to alter a pressure condition within the lumen between a pressurized condition and an nonpressurized condition; and
a piston at least partially disposed within the body and moveable into an actuated position in response to the pressurized condition and to an unactuated position in response to the nonpressurized condition; and

an instrument tip coupled to the ophthalmic device handle, the instrument tip movable into an actuated configuration in response to movement of the piston to an actuated position and moveable into an unactuated configuration in response to movement of the piston to the unactuated position, and further comprising at least one of:
a first component selectively movable within the body to selectively increase and decrease a rate at which the piston moves to an actuated position; and
a second component selectively movable within the body to selectively increase and decrease a rate at which the piston returns to an unactuated position.

10. The system of claim 9 , wherein the fluid source is integrated into a surgical console.

11. The system of claim 9 , wherein the instrument tip comprises at least one of forceps or scissors.
