Which stapling device delivers two rows of double staple lines and has the ability to transect tissue between the staple lines with a blade?

The stapling device that delivers two rows of double staple lines and has the ability to transect tissue between the staple lines with a blade is the linear cutter. This device is specifically designed to provide both a secure closure of tissue and a cut in a single step, which is essential in surgical procedures that require both functions, such as in gastrointestinal surgeries or thoracic procedures.

The linear cutter achieves this by using an integrated blade that cuts through the tissue, located between the two rows of staples, ensuring clean division while simultaneously securing the tissue edges. This design minimizes the risk of complications associated with opening the tissue and resecuring it with separate stapling techniques.

In contrast, the other options do not fulfill the same role; for instance, a stapler with a single row would not provide the necessary dual row of staples for adequate closure, while clips and ties are not designed for transecting tissues efficiently. The Endo GIA is a type of linear cutter but is not explicitly described as delivering double staple lines — it aligns more with delivering a single row of staples. Thus, the linear cutter stands out due to its dual functionality in stapling and cutting.
