Abstract
A cannula ingress system may include a tip stabilization mechanism having a tip stabilization mechanism distal end and a tip stabilization mechanism proximal end, a fixation mechanism, a hypodermic tube having a hypodermic tube distal end and a hypos dermic tube proximal end, and a tip having a tip distal end and a tip proximal end. The tip may be disposed within the hypodermic tube wherein the tip distal end extends from the hypodermic tube distal end. The fixation mechanism may be disposed within a fixation mechanism channel of the tip stabilization mechanism. The tip stabilization mechanism may be disposed over the tip and the hypodermic tube distal end.

An instrument comprising:
- a hypodermic tube having a hypodermic tube distal end and a hypodermic tube proximal end wherein the hypodermic tube has dimensions configured for performing ophthalmic surgery;
- a tip having a tip distal end and a tip proximal end wherein the tip proximal end is disposed in the hypodermic tube and wherein the tip distal end extends out from the hypodermic tube distal end;
- and
- a tip stabilization mechanism having a tip stabilization mechanism distal end, a tip stabilization mechanism proximal end, a tip stabilization mechanism outer diameter, and a tip stabilization mechanism inner diameter wherein the tip stabilization mechanism inner diameter is configured to prevent the tip from deforming when the tip is inserted into a valved cannula.
