Lotus Ultrasonic Scalpel

Energy Transfer

Lotus directs compression energy into the target tissue. Energy is transferred quickly, denaturing the tissue protein and rapidly forming a coagulum. At the same time the central blade cuts through the tissue as the Teflon jaw is closed. The result is fast, haemostatic cutting.

Traditionally ultrasonic scalpels have the opposite properties to a torsional waveguide. Their powerful compression forces are present at the tip of the active blade and the weaker frictional forces are used to cut and coagulate. This explains the slow cutting of these longitudinal systems and highlights the danger that powerful compression energy is directed away from the cut site. This is known as “distal-drilling” and can potentially damage vital structures without the surgeon’s knowledge.
The torsional waveguide is much safer as it only has weak frictional forces at the tip of the active blade.

– Fast, bloodless tissue dissection
– Secure vessel sealing
– No distal drilling from instrument tip
– Minimal lateral thermal spread
– Significantly reduces tissue charring
– Minimal smoke for improved visibility
– All-in-one grasper, coagulator and dissector
– Cutting and sealing in one action
– Less instrument exchange
– No electricity directed through the patient
