Additional Manufacturer Narrative
The device was returned to stryker sustainability solutions for evaluation.Visual inspection of the received complaint device, revealed the presence of bio-burden on the tip and the blade had been fragmented from the jaw.A review of the dhr supports that the device met all inspection and test criteria prior to release from stryker.Therefore, the most likely root causes are: shipping damage, handling damage, damage or separation to the white teflon pad or black pad replacement component(s), too much force or torque applied to instrument, or grasping/pulling, applying pressure between instrument blade and tissue pad without having tissue between them, incidental and prolonged activation against solid surfaces, such as bone, metal or plastic, attempting to bend, sharpen, or otherwise alter the shape of the blade.The instructions for use (ifus) state: ¿care should be taken not to apply pressure between the instrument blade and tissue pad without having tissue between them.Clamping the tissue pad against the active blade without tissue on the full length of the blade will result in higher blade, clamp arm and distal shaft temperatures and can result in possible damage to the instrument.If this occurs, there may be an instrument failure, and the generator touchscreen displays a troubleshooting message." for optimal performance and to avoid tissue sticking, clean the instrument blade, clamp arm, and distal end of the shaft throughout the procedure by activating the instrument tip in saline.Note: do not touch the instrument to metal while activated.Note: do not clean the blade tip with abrasives.It can be wiped with a moist gauze sponge to remove tissue, if necessary.If tissue is still visible in the clamp arm, use hemostats to remove residue, taking care not to actuate the hand piece.If desired, the instrument may be unplugged.If tissue is still visible in the clamp arm, use hemostats to remove residue, taking care not to actuate the hand piece.If desired, the instrument may be unplugged.Do not introduce or withdraw the instrument with the jaws open through a trocar sleeve as this may damage the instrument.Keep the clamp arm open when back cutting or while the blade is active without tissue between the blade and tissue pad to avoid damage to the tissue pad and increased blade, clamp arm and distal shaft temperatures.During benchtop testing of vessels >5 mm, the strongest vessel seals were achieved by allowing the advanced hemostasis mode to completely transect the targeted vessel.Use the torque wrench (already mounted to the shaft) to tighten the blade onto the hand piece.Turn the torque wrench clockwise while holding only the gray hand piece until it clicks twice indicating that sufficient torque has been applied to secure the blade.Note: do not use any other means than the torque wrench to attach or detach the instrument from the hand piece.Note: do not torque the instrument by hand without the torque wrench or damage may occur to the hand piece.Note: hold only the gray hand piece and not the instrument handle while applying the torque wrench.The instruments allow for the coagulation of vessels up to and including 7 mm in diameter, using the advanced hemostasis hand control button.Do not attempt to seal vessels in excess of 7 mm in diameter.If activation is unintentionally stopped while sealing, maintain jaw closure and reactivate.The instrument can be used for dissection, grasping, coagulation, and cutting between the blade and clamp arm.Note: to achieve complete sealing, the trigger should be fully closed and the vessel fully contained between clamp arm and blade of device.An audible and tactile "click" indicates full trigger closure.To achieve full closure of the jaws of the device, squeeze the plastic trigger until you feel it stop against the plastic handle (plastic to plastic) (illustration 9).If full trigger closure is released prior to or during activation on tissue, an audible and tactile "click" is evident.Increase grip force until full trigger closure is achieved.The reported event will continue to be monitored through post-market surveillance.
