Apparatus of the type for automatically performing punching and stapling operations upon successive stacks of sheets of material, typically stacks of collated paper. The apparatus is characterized by an arrangement which performs the two separate operations of punching and stapling on the same edge portion of a stack in a single straight-line pass of the material through the apparatus, using a compact structure with a single control arrangement. In the apparatus, the stacked sheets are fed to a ...

The surgical stapling instrument is provided with an integral cartridge holders as well as a retaining pin and recess which serves to align the cartridge holder relative to the anvil while retaining the distal actuator bar from pivoting into an open position. In addition, the stapling cartridge is provided with four rows of staggered staples in order to provide a stapled seam through which blood is precluded from flowing.

Method of impact stapling with an impact stapler having a staple with integral pointed target-penetration and securing forward section, rear hammer section, and medial compression shear section, the forward section having a threaded object-securing surface rearwardly of its pointed forward target-securing end. The staple is propelled into a target by a percussion-ignited propellant charge, and the forward section is secured by initial point penetration and subsequent compression shear of the med...

The instrument is adapted to associate with a staple-carrying cartridge having a plurality of staples therein. The instrument is manually powered and includes an impact mechanism for forming the staples. A nose portion is rotatably mounted in a hand-held main body portion and adapted to mount the staple-carrying cartridge so that the stap...

This invention relates to a sheet fastening apparatus comprising sheet bundle conveying means for conveying sheet bundles and sheet bundle fastening means for fastening sheet bundles. The sheet bundle fastening means is disposed on either side, of the sheet bundle, extending substantially parallel in a sheet conveyance direction and fastens the sheet bundle at least at a position upon stop of conveyance of the sheet bundle by the sheet bundle conveying means.

A surgical stapling device particularly suited for endoscopic procedures is described. The device can be used with both articulating and non-articulating disposable loading units and has a sensing mechanism for sensing the type of disposable loading unit secured to the device.

An apparatus for achieving hemostasis and pneumostasis along a staple line by utilizing a compliant bioabsorbable foam buttress which may be attached to one jaw of a surgical stapling apparatus by a biocompatible releasable adhesive.

A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of ...

A surgical stapling device for applying an array of surgical staples to tissue is provided. The stapling device includes an approximation mechanism for moving a cartridge assembly and an anvil assembly between spaced and approximated positions and a firing mechanism for ejecting the array of staples from the cartridge assembly. A single trigger is operable to effect approximation and firing of the device. The device also includes an alignment pin assembly which can be selectively manually or aut...

To permit simultaneous stapling of a plurality of folded sheet products (3) in compact space, the sheet products are opened in V shaped formation by carrying them on zig-zag or accordion-pleat carrier elements (1, 1'). The folded elements are transported to stapling systems (8-13), in a direction transverse to the central plane (20) of the folded products. Staple heads (13) move staples against the folded back of the folded products and are closed by a staple counter or closing elements (12) low...
