Abstract:
A process for forming a link mechanism unit included in an endoscopic forceps link mechanism, said process comprising:positioning at least two links to define a coupling pin insertion hole passing through said at least two links at a link coupling portion;inserting a coupling pin into said coupling pin insertion hole so that a head provided at one end of said coupling pin is located in a counterbore formed in a mouth portion of said coupling pin insertion hole while the other end of said coupling pin is projected from said coupling pin insertion hole;placing said at least two links with said coupling pin inserted therein onto a table so that both an end face of said head and an outer open end face of said counterbore contact said table while said head is spaced from said counterbore; andriveting said other end of said coupling pin to couple said at least two links by said coupling pin, so that said end face of said head is positioned inwardly recessed from said outer open end face of said counterbore.
