Duoblade features a uniquely designed tapered cutting edge with a doubly insulated structure, incorporating a highly durable oxide layer. This advanced technology enables exceptionally low-temperature soft tissue dissection, limiting tissue temperatures to near 100°C.
Infrared thermal images for the Duoblade and Traditional Electrosurgery in Cut mode at 35W.
DATA
Duoblade is designed to minimize four key factors
Operating temperature, Thermal injury, Bleeding, and Surgical smoke.
Play Overview
Low Operating Temperatures ¹
Duoblade operates near 100℃
Traditional electrosurgery operates up to 250℃
Minimal Thermal Injury ²
Histology studies using Masson’s Trichrome confirms minimal thermal injury (red) with Duoblade.
Up to 70% reduction in thermal injury compared to traditional electrosurgery devices. (50W CUT mode)
Duoblade incision - low thermal injury.
Traditional device - significant thermal injury.
Exceptional Hemostasis ³
Quantification of blood loss demonstrated outstanding hemostatic performance at the CUT & COAG 35W setting. Duoblade showed significantly lower estimated blood loss compared to a scalpel and other competing advanced energy blades. (P < 0.05)
Blood Loss Quantification
Duoblade® reduced blood loss by more than 93 % compared with a scalpel.
Less Surgical Smoke ⁴
Innovation to promote a cleaner surgical environment. With lower operating temperatures, Duoblade reduces surgical smoke by generating less smoke particles.
Low-profile integrated distal suction provides additional reduction of smoke helping improve overall visualization of the surgical site.
