Microsurgical probe
View Patent ↗Microsurgical probes having a distal tip with a flat outer surface and a flat inner surface, and methods of forming such probes, are disclosed.
1. A method of forming a vitrectomy probe, comprising;
disposing a tubular needle within a collet;
rotating said collet and said needle at high speed;
providing a tool having a generally flat distal surface with a convex spherical projection extending from said generally flat distal surface;
contacting an edge of a distal end of said needle with said convex, spherical projection; and
moving said tool across said distal end of said needle from said edge to slightly past a centerline of said needle so that said distal end of said needle is formed into a closed distal tip having a flat outer surface and a flat inner surface.
