Abstract
Within the framework of R&D activities in the field of microsystems technology, the Institute for Microstructure Technology of Karlsruhe Research Center among others has started to improve the functionality of existing medicotechnical instruments by increased integration of microtechnical components. On the basis of microsystems fabrication techniques, completely novel medical endoscope systems have become feasible. In cooperation with clinical, technical and industrial partners, a novel endoscopic operation system based on microsystems technology is being developed by the Institute for Microstructure Technology and the Aesculap AG company, Tuttlingen within the framework of the MINOP joint project. This new system shall be applied above all in the field of neurosurgery. This newly conceived endosystem is characterized by a multitude of novelties. It can perform a number of both sensor and actor functions. Due to its extremely small outer diameter, it can be applied through minute openings. As a result of the integrated microfluidic control system, the flexible endoscope can be moved to the actual site of operation on a previously specified path. This will allow future bi- and triportal neuro-endoscopic interventions for critical operations in the brain area. The different lumina of the flexible endoscope fulfill various functions. Via the optical fibers, laser radiation may be led to the distal end of the endoscope. Using microtechnical fabrication methods, special plastic microlenses have been produced. The working channel can be applied for rinsing and removal. Furthermore, the cleaning of the optics or the taking of tissue samples are possible. If required, another laser fiber can be driven forward through the working channel for selective therapy. For the first time, high-performance microinstruments have been developed on the basis of novel materials. These instruments can be applied either through the working channel or through an additional trocar.
