Another feature, he points out, is the built-in tremor filter that eliminates the minute trembling of human hands. This enables ultra-precise work that human hands can hardly achieve. Moreover, he explains, haptic feedback ensures that the surgeon avoids areas that should not be touched: ‘The robot tells me if there is any resistance or if the stress on the tissue is too much. That is very helpful and makes the operation even safer and less taxing for the patient.’ It is also less taxing for the surgeons. During the procedure they sit at an open console in front of a height-adjustable workstation and can monitor the entire OR, which is ‘an important safety feature,’ as Professor Staib underlines.
The system provides high resolution images in up to 6x magnification. The camera is controlled by the surgeon’s eye movements, the instruments inside the patient body are controlled by the surgeon’s hands. ‘We are very happy that the system is an open platform which allows us to connect our own camera,’ says Professor Staib and explains that ‘Asensus has developed several adapters while other manufacturers force customers to buy their optical system.’
A further – financial – advantage is the use of standard instruments and trocars. Other systems require specific components that have to be replaced after a few operations, but the Senhance system works with trocars used in hospitals. The robotic instruments can be sterilised and reused – ‘a sustainable and cost-saving approach,’ Professor Staib emphasises.
