A staple line leak usually happens in the 3rd or 4th week after surgery, when a few staples pop out (usually for unknown reasons). This can allow gastric contents to leak out from the sleeve and into the abdominal cavity. Most of the time when this happens it results in a small fluid collection,...
Electrosurgical stapling apparatus
InactiveUS7207471B2Reduces or prevents staple line and cut line bleedingShort and strengthSuture equipmentsStapling toolsStaple lineEngineering
An electrosurgical stapling apparatus is provided which uses thermogenic energy as well as surgical fasteners or staples for strengthening tissue, providing hemostasis, tissue joining or welding. The thermogenic energy also strengthens tissue in proximity to a staple line and knife cut line and provides hemostasis along the staple and cut lines formed by the staples and a knife blade during surgical stapling. The use thermogenic energy provides short-term hemostasis and sealing, and reduces or prevents staple line and cut line bleeding, while the stapling features provide short and long-term tissue strength and hemostasis. The stapling apparatus further substantially reduces or prevents knife cut line bleeding by energizing a knife blade for cauterizing tissue while it is being cut. In one embodiment, energy is applied to the anvil to energize the staples as they make contact with the anvil.
