Claim Text:
1. An instrument comprising: a handle having a handle distal end and a handle proximal end; a piston having a piston distal end and a piston proximal end, the piston disposed in the handle; an actuation structure of the handle having an actuation structure distal end and an actuation structure proximal end; a nosecone having a housing tube housing; a first link, the first link fixed to the actuation structure by a first link pin and the first link fixed to the nosecone by a second link pin; a first spacer disposed over a portion of the first link pin extending from the first link, the first spacer configured to prevent movement of the first link relative to the first link pin; a second spacer disposed over a portion of the second link pin extending from the first link, the second spacer configured to prevent movement of the first link relative to the second link pin; a second link, the second link fixed to the actuation structure by a third link pin and the second link fixed to the nosecone by a fourth link pin; a third spacer disposed over a portion of the third link pin extending from the second link, the third spacer configured to prevent movement of the second link relative to the third link pin; a fourth spacer disposed over a portion of the fourth link pin extending from the second link, the fourth spacer configured to prevent movement of the second link relative to the fourth link pin; a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end wherein the housing tube proximal end is disposed within the housing tube housing, the flexible housing tube having dimensions configured for performing ophthalmic surgical procedures, the flexible housing tube having an ultimate tensile strength in a range of 1000 to 1100 MPa; and an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the actuation structure and the flexible housing tube wherein the optic fiber distal end is adjacent to the housing tube distal end and wherein a portion of the optic fiber is fixed to the housing tube.
