Frequently Asked Questions

  • Does the knife blade get reused with each firing?

    Absolutely not! Every cartridge comes with a new sterile knife blade. Using a new knife for each firing ensures that it will never dull through repeated use and reduces the risk of cross contamination that exists when reusing the same knife blade.

  • Does the knife cut beyond the last row of staples?

    Absolutely not. The staple line continues well beyond the cut line. The knife slot on the cartridge does extend beyond the staples to house the tissue gap control mechanism.

  • Which cartridges can be used with the Endo GIA™ universal stapler?

    All straight and Endo GIA™ Roticulator™ cartridges can be used with all universal instruments (GIA™ universal, Endo GIA™ universal and Endo GIA™ universal XL).

  • What is the shaft diameter of the Endo GIA™ universal stapler?

    The shaft diameter of the Endo GIA™ universal is 12 mm. All cartridges, with the exception of the 4.8 reloads, are 12 mm. The 4.8's cartridges (green) are 15 mm to accommodate the physical height of the 4.8 staple. A 10-15 mm Versaport™ Plus trocar is available to accommodate the 4.8 cartridges, reorder code 179078.

  • How many times can the Endo GIA™ universal instrument be reloaded?

    All three universal instruments (GIA™ universal, Endo GIA™ universal and Endo GIA universal XL) can be loaded and fired 25 times.

  • Why do I have to squeeze the handle multiple times?

    The Endo GIA™ universal stapling system compresses tissue as it is fired. The tissue gap control mechanism compresses tissue while it simultaneously lays down a staple line and transects the tissue. To accomplish this sequential tissue compression, the instrument is fired in 15 mm increments with each full squeeze of the handle. This action moves the tissue gap control mechanism 15 mm with each squeeze, to physically pull the anvil and staple cartridge together to sequentially compress the tissue as it fires. This provides consistent staple formation even at the distal end of the cartridge.

  • How do I know which staple size to use?

    Per the Instructions For Use (IFU) booklet, the 2.0 mm cartridge (gray) should be used on tissue that can comfortably compress to .75 mm - 1.0 mm. The 2.5 mm cartridge (white) should be used on tissue that can comfortably compress to 1.0 mm -1.5 mm. The 3.5 mm cartridge (blue) should be used on tissue that can comfortably compress to 1.5 mm - 2.0 mm. The 4.8 mm cartridge (green) should be used on tissue that can comfortably compress to 2.0 mm.

  • How do you fire the instrument?

    **Please refer to the Instructions for Use (IFU) booklet for complete instructions. Once inside the cavity, open the jaws. Squeeze the handle once to close the jaws on the tissue. Press the green safety button. To fire the instrument, squeeze the handle. Continue to squeeze the handle until the cartridge has been fully fired. Pull back on the black retraction knobs to open the jaws.

  • How do you open the jaws of the stapler?

    To open the jaws of the instrument, pull back on the black retraction knobs.

  • Why don't the jaws close tight on tissue?

    By design, all universal instruments (GIA™ universal, Endo GIA™ universal and Endo GIA™ universal XL) offer an atraumatic jaw closure. This allows surgeons the flexibility to reposition the instrument after closing the jaws but before firing. Specifically, the jaws of the instrument can be repositioned on tissue prior to firing while minimizing bruising. Although the jaws may not appear tight upon closure, the tissue gap control mechanism physically pulls the cartridge and anvil together compressing tissue during firing.

  • Why does the handle sometimes snap when I try to fire across thick tissue?

    The handle does have the potential to “snap” if it is fired into tissue that is outside the indicated range. Should the handle snap, remove the instrument and cartridge and consider the following options:

    • Change to a new larger size stapler and cartridge
    • Perform more dissection
    • Choose a different angle of approach with a new larger staple
    • Choose a different means of transection/closure

  • What positions does the Endo GIA Roticulator™ SULU articulate to?

    The Endo GIA Roticulator™ SULU articulate to 22 and 45 degrees in both directions.
