Abstract
Membrane forceps for performing an ILM or ERM peel procedure include a handle, a tube extending from the handle, and forceps jaws extending from the tube. The forceps jaws may be configured to grasp an ILM or ERM, and may include an outer surface having a roughened surface. The roughened surface may be structurally configured to aid in gaining an edge of the ILM or ERM.
Claims15
Membrane forceps for performing an ILM (internal limiting membrane) or ERM (epiretinal membrane) peel procedure, comprising:
- a handle;
- a tube extending from the handle;
- and
- forceps jaws extending from the tube, the forceps jaws being configured to grasp an ILM or ERM between two opposing grip faces configured to abut each other when the forceps jaws are closed, the forceps jaws also comprising an outer surface, external to the grip faces, having a laser cut array of peaks, the array of peaks being structurally configured to aid in grasping the ILM or ERM and gaining an edge of the ILM or ERM;
- wherein the array of peaks comprise surface features having a peak to valley height within a range of about 3-20 microns;
- wherein the array of peaks comprise an array of points extending away from the outer surface in a knurl pattern;
- and
- wherein the array of peaks are disposed on a first plane substantially parallel to leading edges at distal-most ends of the forceps jaws, wherein the leading edges lie in a second plane substantially perpendicular to a longitudinal axis of the tube.

A surgical instrument for performing an ILM (internal limiting membrane) or ERM (epiretinal membrane) peel procedure, comprising:
- a handle;
- a tube extending from the handle;
- and
- forceps jaws extending from the tube, the forceps jaws comprising a first jaw and a second jaw, the first and second jaws being asymmetrical and having a leading edge, at a distal-most end of the jaw, extending obliquely relative to a longitudinal axis through the surgical instrument, each of the first jaw and the second jaw comprising a respective grip face, wherein the respective grip faces are configured to abut each other when the forceps jaws are closed, and wherein the first and second jaw further comprise an outer surface, external to the grip faces, having a laser cut array of peaks, the outer surface extending in a proximal direction from the leading edge, the array of peaks being structurally configured to aid in gaining an edge of the ILM or ERM;
- wherein the array of peaks comprise surface features having a peak to valley height within a range of about 3-20 microns;
- wherein the array of peaks comprise an array of points extending away from the outer surface in a knurl pattern;
- and
- wherein the array of peaks are disposed on a first plane substantially parallel to the leading edges, wherein the leading edges lie in a second plane substantially oblique to the longitudinal axis of the surgical instrument.
