Arcuate apparatus for applying two-part surgical fasteners

Apparatus for applying at least one row of two-part surgical fasteners to body tissue, including a frame portion having a handle and an arcuate tissue holding portion extending from the handle, each surgical fastener having a pronged fastener portion and a retainer dimensioned and configured to receive the pronged fastener portion into engaged relation therewith, which comprises:

• a) an arcuately configured fastener holding member disposed on the tissue holding portion and adapted for releasably holding a plurality of said fastener portions;
• b) retainer holding means disposed on the tissue holding portion in opposed relation to and spaced from said fastener holding member for releasably holding a plurality of said retainers in positions opposite said respective fastener portions, said retainer holding means being arcuately configured corresponding to said fastener holding member, the fastener holding member and the retainer holding means being adapted to hold tissue therebetween;
• and
• c) means disposed on said handle for sequentially advancing each of said fastener portions toward said retainers so as to cause said fastener portions to engage said retainers while fastening body tissue therebetween.

Apparatus for applying at least two rows of two-part surgical fasteners to body tissue and for cutting the body tissue, each said surgical fastener having at least a two pronged fastener portion for piercing body tissue, and a retainer member dimensioned and configured to receive said fastener portion in engaged relation such that the fastener portion and the retainer member are respectively positioned on opposite sides of the body tissue, which comprises:

• a) a two-part frame having handle portions and separable arcuately configured sections extending from the handle portions, the handle portions and arcuately configured sections being capable of releasable attachment to each other, the arcuately configured sections each defining an elongated finger portion;
• b) a fastener carrying cartridge having an arcuate configuration similar to one of said elongated finger portions and mounted along one of said finger portions and carrying a plurality of said fastener portions;
• c) a retainer carrying cartridge having an arcuate configuration similar to the other of said elongated finger portions and mounted along said other finger portion opposite said fastener cartridge and carrying a plurality of said retainer members positioned opposite said fastener portions, each said retainer member having apertures dimensioned and positioned for reception of pronged portions of said fastener portions when said fastener portions are advanced toward said retainer members;
• d) means mounted on said handle portions of said frame for sequentially advancing said fastener portions toward said retainer members while piercing body tissue positioned therebetween to effect application of said two-part fasteners to the body tissue;
• and
• e) means to cut body tissue adjacent the location of application of said fasteners.

Apparatus for applying at least one row of two-part surgical fasteners, including a frame portion having a handle and an arcuate tissue holding portion extending from the handle, each surgical fastener having a pronged fastener portion and a retainer, which comprises:

• a) arcuate means disposed on the tissue holding portion for holding said fastener portions of said two-part surgical fasteners;
• b) arcuately configured retainer cartridge disposed on the tissue holding portion having means for holding a plurality of retainers in positions opposite said fastener portions, the fastener holding means and the retainer cartridge being adapted to hold tissue therebetween;
• c) a plurality of retainer mounting elements located in said arcuately configured retainer cartridge for releasably engaging and holding said retainers;
• and
• d) driving means for sequentially driving said fastener portions of said two-part fasteners through tissue and into engagement with their respective opposed retainers.

Apparatus for applying at least one row of surgical fasteners including a frame portion having a handle and an arcuate tissue holding portion extending from the handle, which comprises:

• a) first arcuate member disposed on the tissue holding portion for holding at least one row of fasteners;
• b) second arcuate member disposed on the tissue holding portion configured and dimensioned to cooperate with the first arcuate fastener member to hold tissue therebetween;
• c) a fastener driver slidable along an arcuate path through said tissue holding portion for sequentially driving the fasteners along the row into tissue from the first arcuate member toward the second arcuate member;
• and
• d) a slidable control member disposed on said handle for advancing said fastener driver.

Apparatus for applying at least one row of two-part surgical fasteners, including a frame having a handle portion and an arcuate tissue holding portion extending from the handle, each surgical fastener having a pronged fastener portion and a retainer, which comprises:

• a) first arcuate means disposed on the tissue holding portion for holding the fastener portions of the two-part surgical fasteners;
• b) second arcuately configured member positioned on the tissue holding portion opposite the first arcuate means, the first means and the second member adapted to hold tissue therebetween;
• and
• c) driving means disposed on said handle portion and slidable along an arcuate path into said tissue holding portion for sequentially driving the fastener portions of the two-part fasteners from the first means into engagement with their respective opposed retainers on the second means through tissue position in said tissue holding portion.

Apparatus for applying at least one row of surgical fasteners, including a frame portion having a handle and an arcuate tissue holding portion extending from the handle, which comprises:

• a) a first arcuate fastener cartridge disposed on the tissue holding portion for holding said fasteners in at least one row;
• b) second arcuate means disposed on the tissue holding portion configured and dimensioned to cooperate with said first arcuate fastener cartridge to position tissue between the first arcuate cartridge and the second arcuate means;
• and
• c) driving means disposed on the handle and being slidable from the handle into the tissue holding portion for driving said fasteners into tissue from said first arcuate cartridge toward said second arcuate means;
• wherein said fasteners are two-part fasteners, including a first fastener portion positioned in said fastener cartridge and a second retainer portion supported by said second arcuate means.
