Abstract
An endoscopic forceps instrument has an inserting portion to be inserted into a body cavity through an endoscope, a clevis, a pair of rivets, and a pair of opposing jaws. The clevis is coupled to a distal end of the inserting portion. The pair of rivets is coupled to the clevis. Each of the rivets has a tip end that is swaged in order to fix the rivet to the clevis. The pair of opposing jaws is pivotably coupled to respective rivets so as to be movable between an open position and a closed position. The pair of rivets is arranged in parallel to each other. Further, the pair of rivets is arranged such that the tip ends thereof, which are swaged and therefore having relatively low mechanical strength, are located and swaged at opposite sides of the clevis.
