Abstract

An exemplary surgical endocutter may include a staple holder; at least one feeder belt having two lateral edges, at least part of at least one feeder belt extending into the staple holder; and staples, wherein each said staple may include a first end frangibly affixed to a corresponding feeder belt, wherein each first end is affixed to the feeder belt at a location laterally spaced from the longitudinal centerline of the feeder belt, and a second free end; and wherein the staples form at least one row, each row including at least two said staples; wherein staples in least one row are staggered relative to said staples in at least one other row. Another exemplary surgical endocutter may include a feeder belt; staples frangibly connected to the feeder belt; and at least one wedge movable relative to the staples in a direction substantially longitudinal relative to the feeder belt; wherein at least one wedge both directly engages a plurality of staples and disconnects a plurality of staples from the feeder belt in a single continuous motion of the wedge.

Claims (16)

1. A surgical endocutter, comprising:

a staple holder;

at least one feeder belt with at least one substantially planar segment having two lateral edges, at least part of said at least one feeder belt extending into said staple holder; and

a plurality of staples, wherein each staple comprises a first end frangibly affixed to a corresponding one of said at least one feeder belt, wherein each of said first ends is affixed to said feeder belt at a location laterally spaced from a longitudinal centerline of said feeder belt, and a second free end, wherein said staples form at least one row, each row including at least two of said staples; wherein said staples in at least one said row are staggered relative to said staples in at least one other said row; wherein at least one of said staples is affixed to and is out of plane relative to said substantially planar segment of said feeder belt; and wherein at least one row of staples is frangibly connected to a corresponding one of said two lateral edges of said at least one feeder belt.

2. A surgical endocutter, comprising:

a feeder belt;

a plurality of staples frangibly connected to said feeder belt; and

at least one wedge movable relative to said staples in a direction substantially longitudinal relative to said feeder belt; wherein at least one said wedge both directly engages a plurality of said staples and disconnects a plurality of said staples from said feeder belt in a single continuous motion of said wedge.

3. The surgical endocutter of claim 2 , wherein at least one said wedge serially engages said staples and serially disconnects said staples from said feeder belt.

4. A surgical endocutter, comprising:

an anvil;

a feeder belt including multiple tabs extending laterally therefrom;

a staple holder that holds at least part of said feeder belt, said staple holder connected to said anvil;

a plurality of staples frangibly connected to said tabs; and

at least one wedge movable relative to said staples in a direction substantially longitudinal relative to said feeder belt; wherein said at least one wedge both directly engages a plurality of said staples and also disconnects a plurality of said staples from said tabs of said feeder belt in a single continuous motion of said wedge; and wherein engagement between said at least one wedge and said plurality of staples causes each staple of said plurality of staples to rotate about a corresponding one of said tabs to which it is frangibly connected, contact said anvil, and deform to a closed configuration.

5. The surgical endocutter of claim 4 , wherein engagement between said at least one wedge and said plurality of staples causes each staple to deform plastically.
