Abstract
An ophthalmic surgical instrument includes a housing and a snare operably coupled to the housing. The snare is configured to transition between an insertion configuration and a deployed configuration, in which the snare is sized to encircle lenticular tissue. The ophthalmic surgical instrument is designed to prevent elevation and/or tilting of the lenticular tissue as the snare transitions toward the insertion configuration to divide the lenticular tissue.
Claims13
An ophthalmic surgical instrument, comprising:
- a housing including:
- a handle body;
- and
- a hollow shaft extending distally of the handle body and defining a longitudinal axis, the hollow shaft having a bottom surface configured to be oriented toward a human eye, the bottom surface defining an opening;
- and
- a snare operably coupled to the housing and including a looped segment defining a length that is parallel with the longitudinal axis of the hollow shaft, the loop segment configured to move between a contracted configuration and a dilated configuration, in which the looped segment assumes a diameter approximating a diameter and shape of a lens of the human eye, wherein the looped segment is configured to sever the lens upon moving toward the contracted configuration, wherein the looped segment overlaps a portion of the bottom surface of the hollow shaft that is distal to the opening and a portion of the bottom surface of the hollow shaft that is proximal to the opening when the looped segment is in the dilated configuration, such that a majority of the length of the looped segment overlaps with the bottom surface of the hollow shaft when the looped segment is in the dilated configuration.
