Abstract
This surgical needle may reduce unwanted and unanticipated tissue distortion and/or tearing and undesirable scar tissue during wound healing. The surgical needle will guide tissue separation more properly along planes of tissue stress, minimizing tissue distortion and improving tissue apposition.
Claims1
A curved surgical suture needle device comprising:
- an elongated shaft having a proximal section with a central suture affixing hole, a central portion, a distal section with a proximal portion and distal end, the distal section transitions from the distal end of the distal section to a tapered piercing point;
- the elongated shaft having an upper side and a concave lower side;
- the distal section having a rounded bottom surface extending along the concave lower side and two side surfaces extending up from the rounded bottom surface towards the upper side to form a single cutting edge at the upper side, the distal section has a tear drop shape cross section that extends the entire length of the distal section with the single cutting edge on the upper side that forms a tip of the tear drop shape cross section and the rounded surface on the concave lower side forming a bottom of the tear drop shape cross section, and the distal section having a cross sectional diameter continually decreasing from the proximal portion of the distal section to the distal end of the distal section;
- wherein the central section having a rounded cross section;
- wherein the tapered piercing point having a conical cross section;
- wherein the single cutting edge does not extend in the tapered piercing point, central portion and proximal section;
- and
- wherein the curved surgical suture needle is configured so that a plane of a cut made by the single cutting edge is on a direct opposite side of the elongated shaft from an edge of an incision being closed.
