Title (EN) SURGICAL STAPLING APPARATUS
(FR) APPAREIL CHIRURGICAL A AGRAFER
Abstract:
(EN) An improved circular anastomosis surgical stapling instrument (10) for joining hollow tubular organs, has a body (12) having a staple-carrying assembly (20) at its distal end, a centered longitudinally extensible and retractable main shaft (16) centered in the body, (12) and an anvil (22) opposed to the staple-carrying assembly, (20) and is characterized by a separate shaft segment (25) frictionably connectible with the end of the main shaft, (16) the shaft segment (25) having a free end and an end carrying the anvil. The main shaft has a hollow free end and the free end of the shaft segment (25) is releasably receivable in the hollow end of the main shaft (16). In a preferred form the end of the main shaft (16) is provided with a plurality of several radially-extending arms (45) positioned to overlie the main shaft (16) but having spring hinges (48) biasing them radially outwardly away from the main shaft (16). The instrument further includes a second shaft segment (54) releasably receivable in the hollow of the main shaft (16) which second shaft segment (54) has a conical pointed unit (52) at its distal end.
(FR) Améliorations apportées à un instrument chirurgical à agrafer, de type pince anastomotique circulaire (10), permettant de relier des organes tubulaires creux. Ledit instrument comprend, à l'extrémité distale d'un corps (12), un ensemble porteur d'agrafes (20), au centre du corps (12) une tige principale extensible et rétractable (16), et face à l'ensemble porteur d'agrafes (20) une enclume (22). L'instrument se caractérise par un segment de tige séparé (25) qu l'on peut relier par friction à l'extrémité de la tige principale (16), ledit segment (25) ayant une extrémité portant l'enclume et une extrémité libre qui s'introduit de manière détachable dans l'extrémité creuse et libre de la tige principale (16). Dans un mode de réalisation préférentiel, l'extrémité de la tige principale (16) comporte plusieurs bras se prolongeant radialement (45) et disposés de manière à recouvrir la tige principale (16), mais munis de charnières à ressort (48) qui les repoussent radialement vers l'extérieur, loin de la tige principale (16). L'instrument comprend de plus un second segment de tige (54) que l'on peut introduire de manière détachable dans la tige principale (16), ledit second segment (54) comportant à son extrémité distale une pièce conique pointue (52).
