Objective
The physiological tremor which may extend up to 0.4–0.6 mm on the instrument tip in case of a well-skilled microsurgeon may cause diffi culties in any fi eld of microsurgery, in spite of using different armrests. The limit of correctness of medical robots is about 0.1 mm so far, but the application of these machines is expensive and not convenient for surgeons because the direct touch via microinstruments with living tissues is impossible.

Method
The effectiveness of the fi ngertip support technique has been proven by randomized analysis by exact measuring of the reduction of tremor.

Results
The 0.1 mm precision could be reached by fi ngertip support. This extra precise work has not been available by hand so far.

Conclusion
The signifi cant effect of fi ngertip support technique in neurosurgery has been certifi ed and published by exact measuring and clinical data.

Our hypothesis could be the indication for trials in any microsurgical work.
