Abstract:
1. A device for manipulating tissue comprising: a tool assembly adapted for insertion into an abdominal cavity having a handle assembly positioned at a proximal end and an elongate tubular member having a longitudinal axis, the elongate tubular member being positioned between the tool assembly and the handle assembly, wherein the tool assembly comprises at least two extendible members adjustable between an insertion condition and an extended condition, each of the extendible members having at least one associated tissue engagement mechanism located at a distal end, wherein each tissue engagement mechanism is capable of controllably and selectively piercing tissue at a tissue site, and a staple forming mechanism comprising movable pistons and a stationary anvil positioned centrally of the pistons; a plurality of staples in a pre-deployed state within the elongate tubular member; a mechanism for automatically feeding individual staples sequentially from the pre-deployed state into a pre-fire state wherein the staple is positioned between the stationary anvil and movable pistons; an actuator positioned on the handle assembly comprising a trigger assembly adapted for moving the movable pistons to form and eject a staple held in the pre-fire state; and an operator-actuated control feature capable of drawing the tissue engagement mechanisms together to form pierced tissue shoulders at each tissue site and approximating the pierced tissue shoulders in proximity to one another by drawing the pierced tissue shoulders towards the longitudinal axis from a position laterally spaced from the longitudinal axis.
