Definitions

  • This invention relates to a surgical stapling apparatus and is more particularly concerned with an improved circular anastomosis surgical stapler.
  • instruments of the types exemplified by these references include a main body which is provided with a staple-holding assembly at its distal end and a longitudinal connecting shaft which is axially movable within the body and extends outwardly from the distal end of the body.

  • tissue to be stapled is fastened about the staple-holding assembly and about the anvil assembly and clamped between them.
  • the clamped tissue is then stapled by driving a plurality of staples from the staple-holding assembly so that the ends of the staples pass through the tissue and are clinched by contact with . the anvil assembly.
  • the forces required to operate the instrument to eject the staples are applied by the operator of the instrument to one or more actuator elements located at or near the proximal end of the body of the instrument.
  • Means are also provided for causing the shaft to advance and retract. These means are generally at the proximal end of the body of the instrument.
  • the distal and proximal portions of the instrument are joined by the longitudinal connecting shaft structure along which the actuating forces and motions are transmitted to the distal operating elements.
  • This type of construction including relatively widely- spaced distal and proximal portions, is conventionally used.
  • the sections of the colon to be joined are, respectively, secured manually about the staple-holding assembly and the adjacent shaft portion and about the anvil of the instrument and the adjacent shaft portion.
  • the head and anvil are then drawn together by causing the longitudinal connecting shaft to the end of which the anvil assembly is rigidly mounted to retract in the instrument body, so that the anvil assembly approaches the staple-holding assembly carried by the instrument body, and thereupon the stapling operation ensues.
  • a serious problem with the procedure just described is that, when using surgical stapling devices of the prior art, the .
  • surgical stapling instruments are constructed so that they can be economically discarded after use in a single surgical procedure, i.e., so-called disposable instruments.
  • a disposable instrument is sold in sterile condition in packaging designed to keep the instrument sterile until used. After the instrument has been used in a surgical procedure, it is discarded. In this way, all difficulty and expense associated*with cleaning, sterilizing, and reloading the instrument are entirely avoided.

  • the free end of the shaft which remains after the end segment is removed is provided with movable tissue-restraining members to prevent tissue from slipping off the shaft end, and the removable end segment, which releasably interconnects with the free end of the shaft, if formed with a shroud or hood which depresses the restraining members when the end segment and the main body of the shaft are releasably joined.

  • the surgeon has complete freedom of movement and visibility and is not hampered or constrained by limitations of the stapling instrument as he would have been when using instruments of the prior art.
  • the shaft segment 25 is again interconnected with the main shaft 16 by inserting shaft end portion 31 into the hollow end of shaft 16 until detents 30 interlock in recess 32.

Abstract

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).
