Abstract
A surgical suturing tool comprising a suture needle holder and suture needle is disclosed. The needle includes a groove in its sidewall which leads to a blind hole to receive one end of a suture which is secured therein by swedging.
Claims10
A surgical suturing tool, comprising:
- a) a suture needle comprising an elongated essentially straight shaft which traverses an essentially linear path of travel and having a first end tapered to a point, a second end, and a medial portion between the first end and second end, said medial portion having an axially aligned groove leading to a blind hole into which a surgical suture can be fixedly secured, said groove oriented to lead the surgical suture out of a side surface of the suture needle at an angle downward toward the proximal end of the needle opposite the point;
- and
- b) a suture needle holder comprising:
- an elongated tube having a proximal end and a distal end and having an outer wall extending there between enclosing an internal cavity;
- the distal end having a rounded surface with an external groove of sufficient depth to retain a suture therein;
- a pair of wings adjacent the distal end, each wing being pivotable from within the tube at a first end and having a second end which is radially extensible, the second end of said wing having a blind hole for removably receiving said suture needle in said blind hole, said needle being aligned substantially parallel with said elongated tube;
- a control element mounted on the proximal end of the tube, operatively connected to said pair of wings for pivoting purposes;
- and
- the tube further including a flushing port mounted near the proximal end, said flushing port being in fluid communication with the distal end.

A method for surgically suturing a wound, comprising the steps of:
- fastening two swaged suture needles to blind holes in wings of a suture needle holder such that said needles will follow an essentially linear path of travel;
- attaching a suture to a blind hole along a side of each needle, said blind hole having a groove leading thereto, said groove oriented to lead the surgical suture out of a side surface of each suture needle at an angle downward toward a proximal end of each needle opposite the point of each needle;
- placing the suture within a suture retaining groove;
- tensioning the suture;
- inserting the suture needle holder into a wound to be sutured;
- extending the suture needle away from the suture needle holder;
- withdrawing the suture needle holder outwardly such that the needle penetrates the tissue to be sutured by the suture needle;
- disengaging the suture needle from the suture needle holder;
- pulling the suture needle and suture through the tissue to be sutured substantially parallel to said needle holder;
- removing the suture needle holder from the patient, and suturing the patient.
