Process for forming endoscopic shaver blade from elongate tube |
摘要 |
A process of forming a one piece weld free endoscopic shaver blade from an elongate metal cylindrical tube includes first cutting the tube first distal end to a predefined opening shape. A mandrel is inserted into the longitudinal tube with its working end adjacent the tube distal end. The tube distal end is further supported and a first die is forced thereon in a direction generally perpendicular to the elongate tube and forming the tube end and defining a shaver blade opening. A second die is forced onto the tube first distal end in a direction generally parallel to the tube longitudinal further forming the tube end and shaver blade opening. The formed shaver blade opening is then machined or edgeformed as needed to a final shaver blade opening and perimeter shape.
