Frequently asked questions
The Signia™ stapler, when used with the Signia™ circular adapter and Tri-Staple™ 2.0 circular single-use reloads, has applications throughout the alimentary tract for the creation of end-to-end, end-to-side, and side-to-side anastomoses in both open and laparoscopic surgeries. The intended purpose of the device is creation of anastomosis. Refer to instructions for use (IFU) for appropriate clinical use.
The Signia™ circular stapling system provides several functionalities you won’t find with any other circular stapler.
- It’s the only circular stapler with powered and intelligent clamping to control compression.††,12,13
- It’s the only circular stapler that allows the user to leak-test the staple line without removing the instrument from the lumen.††,‡‡,14
- It’s the only circular stapler that separates staple and cut functions, confirming staple line formation before engaging the knife.††,12,13
Plus, the system allows you to select from an array of device components to meet your needs, from reusable circular adapters to multiple single-use reload sizes to procedure-specific options.
Adaptive Compression™ technology is designed to give you the feedback you want throughout clamping and firing.1,2 It works in conjunction with the Signia™ stapling system to:
- Determine the compression profile (i.e., proper speed and pressure) based on tissue properties and thickness3
- Use tissue-sensing technology to measure and adapt the amount of applied pressure1,2,12
- Notify you when tissue relaxation occurs, when the staple line is complete, and when the knife blade engages2,15
With this built-in intelligence to control compression,3 you may avoid overcompressing the tissue§§,◊◊,2,5,13 and prevent damage to the anastomosis.◊◊,16
The Signia™ circular stapler uses a Tilt-Top™ anvil, which tilts to facilitate easier removal from the anastomotic site.¶¶,17,18
The Signia™ circular stapler produces 88% less waste than the Echelon Circular™* powered stapler.##,19 It also provides greater protection against anastomotic leaks¶,8 — and procedures where no anastomotic leaks occur are associated with a shorter length of stay and lower costs when compared to procedures with anastomotic leaks.20
