Precision Surgery

Neurosurgery is - even in laboratory settings - by far one of the most demanding surgical fields, since the brain consists of minute and sensitive structures. In order to achieve minimal trauma with maximal target precision probe implantation has to be optimized as well as probe shapes.

Stereotaxic small animal brain surgery

Ongoing research led to the worlds first completely roboterized small animal stereotaxic frame with five independently controllable axes. The system is used for actual implantation of microreccording probes, placement of optical probes and even for micromachining of bone structures. Its precision lies in the range of some 10 µm.
