Apparatus and method for applying surgical staples to attach an object to body tissue
First Claim
1. An apparatus for applying surgical staples for endoscopic hernia repair comprising:
- a handle portion having a stationary grip portion and a movable trigger pivotally mounted with respect to the stationary grip portion;
an elongated tubular portion extending from the handle portion, the elongated tubular portion having a longitudinal axis and dimensioned and configured for insertion through a cannula;
a staple supporting portion pivotally connected to a distal end portion of the elongated tubular portion, the staple supporting portion pivotable between a first position in alignment with the longitudinal axis of the tubular portion and a second position at an acute angle to the longitudinal axis;
a plurality of staples supported in the staple supporting portion;
an actuator spaced from the staple supporting portion and operatively associated therewith, wherein the actuator is slidable in a direction parallel to the longitudinal axis of the tubular portion to thereby pivot the staple supporting portion between the first and second positions;
a staple pusher operatively associated with the trigger and movable between a proximal and distal position, wherein movement of the trigger towards the stationary grip portion advances the staple pusher distally; and
an anvil positioned at a distal end of the staple supporting portion, wherein distal advancement of the staple pusher advances one of the staples into engagement with the anvil to deform the staple, the staple pusher being movable to advance one of the staples in both the first and the second position of the staple supporting portion.

Abstract
An apparatus is disclosed for endoscopic application of surgical staples in laparoscopic hernia surgery. The apparatus includes a handle and a generally elongated endoscopic section connected to the handle and extending distally therefrom. A staple storage magazine is provided for storing a plurality of surgical staples at the distal end portion of the endoscopic section. The staple storage magazine is pivotable between a first position in alignment with the longitudinal axis of the endoscopic section and a second position at an acute angle to the longitudinal axis. An elongated pusher system is provided for individually advancing at least one staple at a time distally. A trigger mechanism is provided to actuate the pusher.

11. An apparatus for applying surgical staples in endoscopic hernia procedures comprising:
-
a handle portion having a stationary grip portion and a movable handle movably mounted with respect to the stationary grip portion; an endoscopic portion having a longitudinal axis and extending distally from the handle portion, the endoscopic portion being rotatably mounted to the handle portion and dimensioned and configured for insertion through a cannula to access the surgical site; a staple support pivotably connected to a distal end portion of the endoscopic portion; a plurality of staples supported in the staple support, each staple having a pair of legs extending from a backspan; a stationary anvil mounted to a distal portion of the staple support; a staple pusher operatively associated with the movable handle and moveable in a distal direction to advance a staple distally for deformation by the anvil; a slidable actuator operatively connected to the staple support; wherein the staple support is pivotable from an aligned position in alignment with the longitudinal axis of the endoscopic portion to an articulated position at an angle to the longitudinal axis of the endoscopic portion by movement of the actuator, and the staple pusher is actuable by the movable handle to advance one of the staples when the staple support is in the first position and in the second position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
