Zusammenfassung:The invention discloses methods of manufacturing an anvil for a surgical stapler. In various arrangements, the methods include forming an anvil body by rolling, extruding, metal injection molding or electrochemical machining. Preliminary staple-forming pocket configurations are formed in the anvil body by machining or during the metal injection molding or electro-chemical machining processes. The staple-forming pockets are provided with a final configuration using another manufacturing step such as coining or forging. 本发明公开了制造用于外科缝合器的砧座的方法。在各种布置结构中,这些方法包括通过轧制、挤出、金属注射成型或电化学加工来形成砧座主体。通过机加工或在金属注射成型工艺或电化学加工工艺期间在砧座主体中形成初步钉成形凹坑构型。使用另一个制造步骤(诸如压印或锻造)为钉成形凹坑提供最终构型。
