endoscopic linear stapler
Laparoscopic device that simultaneously cuts and staples tissue in a straight line.
Full Definition
An endoscopic linear stapler is a sophisticated laparoscopic instrument designed to simultaneously divide tissue and create secure stapled anastomoses or closures in a linear fashion. The device fires multiple rows of titanium staples while a blade cuts between the staple lines, creating sealed edges on both sides of the division. These staplers are available in various lengths and staple heights to accommodate different tissue thicknesses and are commonly used in procedures such as bowel resections, gastric procedures, and lung resections. The articulating versions allow for improved access in confined spaces. Proper tissue thickness assessment is crucial to prevent staple line failure or bleeding.
Usage
Usage note: Often abbreviated as ELS; specify cartridge color/height when documenting use.
