Abstract
A surgical stapler utilizing plastic staples and ultrasonic welding to secure the staples in body tissue. The stapler includes a pair of jaws movable between open and closed positions, a handle and trigger assembly for controlling operation of the jaws, and an elongated tubular structure connecting the handle and trigger assembly to the jaws. The stapler also includes an ejection assembly for ejecting at least one staple from one of the jaws against the other of the jaws. An anvil and a horn are positioned in the other of the jaws and are arranged to receive ends of the ejected staple such that the ends overlap between the anvil and the horn. The horn is for melting and bonding at least a portion of the overlapping ends of the staple upon being energized by a predetermined form of energy, and one of the anvil and the horn is movable from within the bonded staple to allow the jaws to be moved to an open position.
