1. An ophthalmic apparatus for performing an ocular surgery, comprising:
- an ophthalmic probe body with a handle portion graspable by a user;
an aspiration port on a proximal portion of the probe body;
an aspiration tube, coupled to the aspiration port, disposed within the probe body and having a lumen arranged to contact aspiration fluid flowing therethrough;
a cutter extending from a distal portion of the probe body and comprising a first cutting member and a second cutting member, the first cutting member being at least partially disposed within and moveable relative to the second cutting member, the first cutting member having a lumen having a first diameter, the second cutting member having a distal end with a port formed therein for receiving patient tissue, the first cutting member configured to be axially displaceable within the second cutting member to sever the patient tissue received in the second cutting member port, wherein the first cutting member also moves within a portion of the lumen of the aspiration tube; and
a motor within the distal portion of the probe body, on an opposite side of the probe body as the aspiration port, wherein the motor is connected directly to the first cutting member to actuate the first cutting member relative to the second cutting member and the lumen of the aspiration tube;
a pneumatic port adjacent the aspiration port on the proximal portion of the probe body; and
a pneumatic channel, inside the probe body, coupled to the pneumatic port and configured to deliver air to at least one side of the motor;
wherein the pneumatic channel runs along a majority of a length of the probe body.

Abstract
An ophthalmic apparatus for performing an ocular surgery may include an ophthalmic probe body having an inner cutting member at least partially disposed within and moveable relative to an aspiration tube within the probe body to facilitate flow of aspiration fluid. A motor within the body may be configured to actuate the inner cutting member relative to the aspiration tube.

8. An ophthalmic apparatus for performing an ocular surgery, comprising:
-
an ophthalmic probe body with a handle portion graspable by a user; an aspiration port on a proximal portion of the probe body; a first stationary aspiration tube, coupled to the aspiration port, having a first aspiration lumen disposed within the probe body, the first aspiration lumen arranged to contact aspiration fluid flowing therethrough; a cutting assembly comprising an axially displaceable cutting member forming a second aspiration lumen, the cutting member movably disposed within a portion of the first aspiration lumen, the first and second aspiration lumens configured to aspirate fluid through the probe body; and a motor within a distal portion of the probe body, on an opposite side of the probe body as the aspiration port, configured to actuate the cutting member relative to the first aspiration lumen; a pneumatic port adjacent the aspiration port on the proximal portion of the probe body; and a pneumatic channel, inside the probe body, coupled to the pneumatic port and configured to deliver air to at least one side of the motor; wherein the pneumatic channel runs along a majority of a length of the probe body. - View Dependent Claims (9, 10, 11, 12, 13, 14)
