Surgical port closure device

1. A method of suturing a surgical port comprising:

providing a port closure device including first and second jaws carried by a longitudinal shaft and moveable between an open and a closed position;

moving the first and second jaws to the open position, wherein a needle is selectively attached to the first jaw thereby positioning a mid-portion of the needle generally perpendicular to a longitudinal axis of the shaft;

moving the jaws to the closed position to pass the needle through live tissue near a port formed in the live tissue, wherein the mid-portion of the needle is generally offset and generally parallel with the longitudinal axis when closed within the jaws;

wherein both the first jaw and the second jaw are not parallel to the longitudinal axis in the closed position;

transferring the needle from the first jaw to the second jaw; and

moving the jaws to the open position with the needle selectively attached to the second jaw.

2. The method of claim 1 , further comprising:

imparting movement to a portion of a handle of the port closure device;

moving a control rod in the shaft in response to the imparted movement of the portion of the handle; and

rotating the second jaw about a transverse axis that is perpendicular to the longitudinal axis of the shaft in response to movement of the control rod, wherein the second jaw rotates towards a position approaching perpendicular relative to the longitudinal axis in the closed position.

3. The method of claim 2 , further comprising:

rotating the first jaw about the transverse axis, simultaneously with rotation of the second jaw, in response to movement of the control rod, wherein the first jaw rotates towards a position approaching perpendicular relative to the longitudinal axis in the closed position.

4. The method of claim 1 , further comprising:

moving a control rod longitudinally; and

moving the first jaw and the second jaw from the closed position towards the open position, wherein both the first and second jaws are not parallel to the longitudinal axis in the closed position and wherein both the first and second jaws approach parallel to the longitudinal axis in the open position in response to movement of the control rod.

5. The method of claim 1 , further comprising:

moving a first blade in the first jaw from an advanced first position to a retracted second position when the first and second jaws are in the closed position and not parallel to the longitudinal axis, wherein the first blade moves within a bore defined along the length of the first jaw.

6. The method of claim 5 , further comprising:

simultaneous to moving the first blade, moving a second blade in the second jaw from a retracted first position to an advanced second position when the first and second jaws are in the closed position and not parallel to the longitudinal axis, wherein the second blade moves within a bore defined along the length of the second jaw; and

wherein the first blade and the second blade are not in the same position at the same time such that when the first blade is in its advanced position, the second blade is in its retracted position, and when the first blade is in its retracted position, the second blade is in its advanced position.

7. The method of claim 1 , further comprising:

transferring, selectively, the needle from the first jaw to the second jaw; and

wherein the needle carries a suture as the needle is selectively transferred form the first jaw to the second jaw.

8. The method of claim 7 , further comprising:

positioning, when the first and second jaws are in the closed position, the mid-portion of the needle parallel to the longitudinal axis.

9. The method of claim 8 , further comprising:

positioning, when the first and second jaws are in the open position, the mid-portion of the needle perpendicular to the longitudinal axis.

10. The method of claim 1 , wherein the step of transferring the needle from the first jaw to the second jaw comprises:

removing a first needle control blade disposed within the first jaw from a fully inserted engagement through a completely bound first aperture formed near a first sharpened end of the needle; and

inserting a second needle control blade disposed within the second jaw through a completely bound second aperture formed near a second sharpened end of the needle.

11. The method of claim 10 , wherein the steps of removing the first needle control blade and inserting the second control blade is accomplished by actuating a needle control switch operatively coupled to a needle control rod extending along the longitudinal axis.

12. The method of claim 1 , wherein the step of moving the jaws to the closed position further comprises:

passing a sharpened end of the needle along a tapered surface on the second jaw and into a needle cavity defined in the second jaw orthogonal to a needle control bore; wherein the tapered surface guides the needle into the cavity in the event the needle is bent while passing through the live tissue.

13. The method of claim 1 , further comprising:

rotating the device about the longitudinal axis and closing the jaws to pass the needle through live tissue near the port's other side.

14. The method of claim 13 , wherein rotating the device about the longitudinal axis includes:

rotating the device about the longitudinal axis in a range from 45° to 315°.

15. The method of claim 14 , wherein the device is rotated about 180° about the longitudinal axis.
