Abstract

An endoscopic surgical instrument for deploying a two part fastener having a male fastener part and a female fastener part, includes a tube having a proximal end and a distal end. An end effector is coupled to said distal end of said tube and is configured to hold the male fastener part and the female fastener part in opposed relation. An actuator is coupled to said proximal end of said tube and is configured to actuate the end effector. A shearing device may be positioned proximate the end effector to shear off a tip of the male fastener part after the male and female fastener parts are moved into locking relation. In addition, the surgical instrument may include a male fastener part having a shaft with a plurality of detent positions. Further, the male fastener part may include a base and a shaft pivotally connected to the base.

9. The endoscopic surgical instrument of claim 1, wherein said male fastener part includes a base and a shaft connected to the base, wherein the shaft includes a plurality of detent positions.

10. The endoscopic surgical instrument of claim 9, wherein the female fastener part is capable of resting in said locking relation at each of said detent positions.

11. The endoscopic surgical instrument of claim 1, wherein said tube is a flexible tube.

12. The endoscopic surgical instrument of claim 1, further comprising at least one control member extending through the tube and connecting at a proximal end to the actuator and at a distal end to the end effector.

13. The endoscopic surgical instrument of claim 1, wherein said male fastener part includes a base and a shaft pivotally connected to the base.

14. The endoscopic surgical instrument of claim 13, wherein the shaft is pivotally connected to the base by a hinge.

15. The endoscopic surgical instrument of claim 13, wherein said shaft is configured to move between a first position in which the shaft is positioned in substantially the same plane as the base and a second position in which the shaft is positioned substantially perpendicular to said base.

16. An endoscopic surgical instrument for deploying a two part fastener having a male fastener part and a female fastener part, comprising:

a tube having a proximal end and a distal end;

an end effector coupled to said distal end of said tube, said end effector configured to hold the male fastener part and the female fastener part in opposed relation;

an actuator coupled to said proximal end of said tube and configured to actuate the end effector; and
