Lotus uses a different type of ultrasonic vibration to turn the power transmitted down the waveguide through 90° and focus it into the target tissue. How it does this is explained below but a simple mathematical model, backed by growing clinical experience, shows that the power delivery can be as much as four times that of conventional longitudinal devices.

• Energy is directed into target tissue only, giving very secure coagulation and very fast cutting.
• Much lower risk of “distal drilling”.
• The waveguide does not depend on friction to generate heat so it can be highly polished, running well below the fatigue limit and so can be re-used – saving cost.
• The compact, lightweight transducer lies within the surgeon’s hand providing a balanced, ergonomic instrument.
• The simple, efficient design provides a cost effective disposable jaw actuator element.
