Abstract

A surgical suturing apparatus includes a suture housing, a needle having a proximal end and a distal end, the needle being mounted within the suture housing for movement about an arcuate path, a drive assembly operably associated with the needle for controlling movement of the needle with a suture secured thereto about the arcuate path in a manner facilitating application of the suture to tissue, and mechanism for determining the position of at least one of the distal end of the needle and the proximal end of the needle at all points along the arcuate path about which the needle moves.

Claims

1. A surgical suturing apparatus, comprising:

a suture housing;

a needle having a proximal end and a distal end, as well as an inner surface and an exterior surface, the needle being mounted within the suture housing for movement about a complete revolution of a predetermined continuous circular path;

a drive assembly operably associated with the needle for controlling movement of the needle with a suture secured thereto about the circular path in a manner facilitating application of the suture to tissue; and

means for determining the position of and providing tactile feedback regarding at least one of the distal end of the needle and the proximal end of the needle at all points along the circular path about which the needle moves, the means for determining position and providing tactile feedback including a spring ratchet pawl lock directly secured along the suture housing for engaging a recess formed along the needle, the spring ratchet pawl lock includes a pawl lock lever arm having a first end pivotally secured to the housing at a position along a forward end of the needle path and a second end extending toward and into contact with the exterior surface of the needle.

2. The suturing apparatus according to claim 1, further comprising means for interfering with movement of the needle along the circular path about which the needle moves.

3. The suturing apparatus according to claim 1, wherein the suture housing is shaped and dimensioned for insertion through a natural orifice of a patient.

4. The suturing apparatus according to claim 3, wherein the suture housing is shaped and dimensioned for passage through an orifice from approximately 3 mm to approximately 24 mm in diameter.

5. The suturing apparatus according to claim 1, wherein the suture housing is shaped and dimensioned for laparoscopic insertion through a trocar.

6. The suturing apparatus according to claim 5, wherein the suture housing is shaped and dimensioned for passage through an orifice from approximately 3 mm to approximately 18 mm in diameter.

7. The suturing apparatus according to claim 1, wherein the spring ratchet pawl lock is secured to the suture housing along a forward end of the needle path.

8. The suturing apparatus according to claim 1, wherein the needle is provided with recess for engagement with the spring ratchet pawl lock.

9. The suturing apparatus according to claim 1, wherein the suture housing includes a first track in which a needle is positioned for movement about the complete revolution.

10. A surgical suturing apparatus, comprising:

a suture housing;

a needle having a proximal end and a distal end, as well as an inner surface and an exterior surface, the needle being mounted within the suture housing for movement about a complete revolution of a predetermined continuous circular path;

a drive assembly operably associated with the needle for controlling movement of the needle with a suture secured thereto about the circular path in a manner facilitating application of the suture to tissue; and

means for determining the position of and providing tactile feedback regarding, a predetermined point on the needle relative to the needle'"'"'s path of travel when the predetermined point is not visually detectable, the means for determining position and providing tactile feedback including a spring ratchet pawl lock directly secured along the suture housing for engaging a recess formed along the needle, the spring ratchet pawl lock includes a pawl lock lever arm having a first end pivotally secured to the housing at a position along a forward end of the needle path and a second end extending toward and into contact with the exterior surface of the needle.

11. The suturing apparatus according to claim 10, wherein the suture housing includes a first track in which a needle is positioned for movement about the complete revolution.
