Powered staplers
Signia™ circular stapler with Tri-Staple™ technology
A circular stapler that combines Signia™ intelligence, Adaptive Compression™ technology, and Tri-Staple™ reloads to empower anastomotic performance.
Description
The Signia™ circular stapler combines powered, intelligent clamping and firing with trusted Tri-Staple™ technology to bring an innovative stapling device to colorectal and general surgery.
Create confident anastomoses.
- Adaptive Compression™ technology: Get real-time feedback1,2 while applying just the right amount of compression.3
- Empowered performance: Less stress on tissue,†,5,6 reduced user variability,‡7 and increased consistency§,7 when creating anastomoses
- Tri-Staple™ technology: Three rows of varied-height staples provide greater perfusion◊,8 and more protection against anastomotic leaks¶,9
You and your patients can depend on the Signia™ circular stapler to deliver a confident staple line#,∆,7,10 while improving outcomes and recovery.∞,8,11,12
