  The construction of a novel surgical instrument is considered, which is also
a probing device providing a signal to the measuring equipment, which after its
interpretation allows to obtain useful information about the section quality
and the biomaterial properties. We propose here some formalized considerations
on the possibility of its implementation for different variables registration.
The idea is also extrapolated into the field of micrurgy which refers to the
microelectrode techniques and the local potential registration in situ.
