Articulating apparatus for endoscopic procedures

1. A surgical device, comprising:

an elongate body portion including an inner actuation shaft movably positioned therewithin and repositionable between a first position and a second position, the inner actuation shaft including an engagement member;

an end effector releasably supported adjacent a distal end of the elongate body portion, the end effector including:

an engagement member corresponding to the engagement member of the inner actuation shaft to facilitate releasable connection of the end effector to the elongate body portion, the end effector being releasable from the elongate body portion when the inner actuation shaft is positioned in the second position and secured to the elongate body portion when the inner actuation shaft is positioned in the first position;

a plurality of surgical anchors; and

a pair of opposed longitudinally extending tines defining a pair of opposed longitudinally extending channels; and

an outer tube, wherein the inner actuation shaft is movably positioned within the outer tube, wherein the engagement of the inner actuation shaft is concealed within the outer tube in the first position and exposed from the outer tube in the second position.

2. The surgical device according to claim 1 , wherein the engagement member of the inner actuation shaft is located at a distal end of the actuation shaft, and the engagement member of the end effector is located at a proximal end of the end effector.

3. A surgical device, comprising:

an elongate body portion including an inner actuation shaft movably positioned therewithin and repositionable between a first position and a second position, the inner actuation shaft including an engagement member; and

an end effector releasably supported adjacent a distal end of the elongate body portion, the end effector including:

an engagement member corresponding to the engagement member of the inner actuation shaft to facilitate releasable connection of the end effector to the elongate body portion, the end effector being releasable from the elongate body portion when the inner actuation shaft is positioned in the second position and secured to the elongate body portion when the inner actuation shaft is positioned in the first position, wherein the engagement member of the inner actuation shaft includes a recess, and the engagement member of the end effector includes a protrusion configured and dimensioned for positioning within the recess;

a plurality of surgical anchors; and

a pair of opposed longitudinally extending tines defining a pair of opposed longitudinally extending channels.

4. The surgical device according to claim 1 , wherein the inner actuation shaft is rotatable within outer tube, rotation of the inner actuation shaft being transmitted to the end effector via connection of the corresponding engagement members of the inner actuation shaft and the end effector.

5. The surgical device according to claim 1 , wherein the end effector includes an outer tube and an inner tube, the inner tube positioned within the outer tube.

6. The surgical device according to claim 5 , wherein the inner tube of the end effector is rotatably supported within the outer tube.

7. The surgical device according to claim 6 , wherein each anchor includes a threaded body portion and a head portion, the head portion defining a pair of opposed radially outer threads and a pair of opposed radial recesses, the pair of radial recesses of each head portion receiving the pair of tines of the inner tube of the end effector.

8. The endoscopic surgical device according to claim 6 , wherein the outer tube of the end effector includes a helical thread along an inner surface thereof.

9. A surgical device, comprising:

an elongate body portion including an inner actuation shaft movably positioned therewithin and repositionable between a first position and a second position, the inner actuation shaft including an engagement member; and

an end effector releasably supported adjacent a distal end of the elongate body portion, the end effector including:

an engagement member corresponding to the engagement member of the inner actuation shaft to facilitate releasable connection of the end effector to the elongate body portion, the end effector being releasable from the elongate body portion when the inner actuation shaft is positioned in the second position and secured to the elongate body portion when the inner actuation shaft is positioned in the first position;

a plurality of surgical anchors;

a pair of opposed longitudinally extending tines defining a pair of opposed longitudinally extending channels; and

an outer tube and an inner tube, the inner tube positioned within the outer tube, wherein the inner tube of the end effector is rotatably supported within the outer tube, wherein the outer tube of the end effector includes a helical thread along an inner surface thereof, wherein the outer threads of the head portion of each anchor project from the longitudinally extending channels defined by the inner tube of the end effector, and engage the helical thread of the outer tube of the end effector.

10. The endoscopic surgical device according to claim 1 , further including a handle assembly supported adjacent a proximal end of the elongate body portion.

11. The endoscopic surgical device according to claim 10 , wherein the handle assembly includes a handle housing, a trigger operatively connected to the handle housing, and a drive mechanism actuatable by the trigger.

12. The endoscopic surgical device according to claim 11 , wherein the drive mechanism is connected to the inner actuation shaft such that actuation of the trigger results in rotation of the inner actuation shaft.

13. The endoscopic surgical device according to claim 1 , wherein the elongate body portion includes a proximal portion and a distal portion, the distal portion pivotably connected to the proximal portion at a pivot point.
