Abstract:

An improved staple for use with an endoscopic stapler has arms which are curved toward each other such that the staple may be crimped so as to cause the arms to move toward each other and thereby lock the staple into place. This crimping action substantially mitigates the likelihood of the staple inadvertently pulling out. The staple also has an abutment bend formed therein to serve as a detent and thereby secure the staple within the jaws of an endoscopic stapler. An endoscopic stapler for effecting use of the improved staple is also disclosed. The endoscopic stapler generally comprises an elongate tubular section which may be inserted through an endoscopic incision into a human body; a handle portion having a trigger for effecting the stapling process; a pair of jaws disposed at the distal end of the elongate tube for positioning and crimping a staple in place; a feed mechanism for advancing a series of staples to the jaws; and a means for selectively adjusting the amount of crimp imparted to the staple. The improved staple and endoscopic stapler of the present invention permit a surgeon to rapidly secure anatomical body portions and/or therapeutic devices in place within the human body without requiring an incision in excess of approximately 1 centimeter.
