Abstract: In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.

Abstract: A method of manufacturing an articulating ophthalmic surgical probe includes providing a cannula having an outer diameter of 20 Ga or less and a slotted tip, permanently attaching a pull wire to the slotted tip, permanently attaching a metal anchor to a distal end of the pull wire, positioning a weld pin within a handle assembly that is sized to fit within a single hand, and welding the metal anchor to the weld pin within the handle assembly.
