Surgical instruments
In one form, a surgical needle has a curved needle body having a first end and a second end and defines an interior region between the first and second ends. The interior region contains a center of curvature of the needle body. The first and second ends each terminate in a point. The needle body has an intermediate portion between the first and second ends, and defines an internal surface facing the interior region and an external surface facing away from the interior region. A recess is thrilled within the external surface of the needle body. In another form, the needle is provided in a sterilized package together with one or more elongate filaments each having a proximal end coupled to the needle body within the recess. A container holds the surgical needle and the filament.
1. A surgical instrument comprising:
a curved needle body having a first end and a second end and defining a convex exterior side and a concave interior side, said concave interior side facing a center of curvature of said needle body, said first and second ends each terminating in a point, said needle body having an intermediate portion between said first and second ends, and a recess formed within said exterior side at said intermediate portion for receiving at least one filament, said needle body has a central axis extending through a geometric center of said needle body from said first end and said second end, a first elongate filament having a proximal end and a distal end, said proximal end being coupled to said needle body within said recess, and
a second elongate filament that is separate from said first elongate filament, said second elongate filament having a proximal end and a distal end, said proximal end coupled to said needle body within said recess, and wherein said proximal end of said first filament and said proximal end of said second filament are coupled to said needle body within said recess in a tandem configuration, one in front of the other, along said central axis when viewed in a cross-sectional plane taken normal to said central axis at said recess.
2. The surgical instrument as recited in claim 1 wherein said first filament is absorbable within organic tissue, and said second filament is nonabsorbable within organic tissue.
