Title
(EN) ANVIL FOR CIRCULAR SURGICAL STAPLER AND ASSOCIATED METHOD OF MANUFACTURE WITH MIM
(FR) ENCLUME POUR AGRAFEUSE CHIRURGICALE CIRCULAIRE ET PROCÉDÉ DE FABRICATION ASSOCIÉ AVEC MOULAGE PAR INJECTION DE MÉTAL (MIM)
Abstract
(EN)
A method is used to manufacture an anvil (10) of a surgical circular stapler (100). The anvil (10) includes a head (12) and a shank (18) extending proximally from the head (12). The method includes forming the head (12)of a surgical circular stapler (100) using a metal injection molding process. The method also includes forming an annular array of staple forming pockets (24) in the head (12). The method also includes machining the shank (18) of the surgical circular stapler (100). The method also includes coupling together the head (12) and the shank (18) of the surgical circular stapler(100) that were separately manufactured.
(FR)
L'invention concerne un procédé qui est utilisé pour fabriquer une enclume (10) d'une agrafeuse chirurgicale circulaire (100). L'enclume (10) comprend une tête (12) et une tige (18) s'étendant de manière proximale de la tête (12). Le procédé consiste à former la tête (12) d'une agrafeuse chirurgicale circulaire (100) au moyen d'un processus de moulage par injection de métal. Le procédé consiste également à former un réseau annulaire de poches de formation d'agrafes (24) dans la tête (12). Le procédé consiste également à usiner la tige (18) de l'agrafeuse chirurgicale circulaire (100). Le procédé consiste également à accoupler la tête (12) et la tige (18) de l'agrafeuse chirurgicale circulaire (100) qui ont été fabriquées séparément.
