Suturing system
A suturing system including apparatus and methods for disposing stitches in a substrate comprising a thread carrier which inserts a thread in the substrate at a first location and withdraws the thread from the substrate at a second location.
1. A thread capture device, comprising:
a thread carrier having a terminal end, said terminal end shaped as a sharpened point of a needle;
a notch disposed in said thread carrier proximate said thread carrier terminal end;
an aperture element having a pair of openings disposed on opposite sides of said thread carrier, said aperture element disposed between said thread carrier terminal end and said notch; and
a first resiliently flexible hook member terminating in a first hook, said thread carrier moves to slidably engage said first hook to pass into said notch disposed in said thread carrier.
2. The device of claim 1 , wherein said notch defines a notch passage having a notch passage first end and a notch passage second end, wherein each of said notch passage first and second ends open on an external surface of said thread carrier.
3. The device of claim 2 , wherein said notch passage disposed in angular relation to a longitudinal axis of said thread carrier.
4. The device of claim 2 , wherein slidable engagement of said first hook with said thread carrier resiliently flexes said first resiliently flexible hook member, wherein resilient flexure of said resiliently flexible hook member moves said first hook into said notch passage.
5. The device of claim 4 , wherein slidable engagement of said thread carrier with said first hook disposes a thread disposed in said aperture element adjacent said first resiliently flexible hook member prior to movement of said first hook through said notch passage, and passage of said first hook through said notch passage captures said thread with said first resiliently flexible hook member.
6. The device of claim 5 , further comprising a second resiliently flexible hook member terminating in a second hook, said second resiliently flexible hook member disposed a distance from said first resiliently flexible hook member, said first hook overlapping said second hook, said thread carrier slidably engages said first hook and said second hook on opposite sides of said thread carrier.
7. The device of claim 1 , wherein said thread carrier tapers approaching said thread carrier terminal end.
8. The device of claim 7 , wherein said thread carrier tapers to a point approaching said thread carrier terminal end, said point capable of penetrating a substrate.
9. The device of claim 8 , wherein said substrate comprises an animal tissue.
