Investigation of application possibilities of optical spectroscopy within the field of surgical resection procedures to spare nerve tissue. Optical spectroscopy enables the possibility to specifically differentiate between different (human) tissues. The hypothesis is that incorporation of this technique into existing medical devices (e.g. medical blade) would enlarge the accuracy and reliability of these devices. Sparing of nerve bundles during surgery can lead to decreased postoperative morbidity rates.
The aim of this pilot study is to prove that an investigational optical spectroscopy system can provide accurate identification of nerve tissue during surgery. Primary Objective: The goal of this pilot study is to evaluate whether optical spectroscopy is able to differentiate between nerve tissue and surrounding tissue. Secondary Objective: During the measurement procedure, possible improvements of the measurement hardware will be recorded and the handling of the optical spectroscopy system during surgery will be evaluated.
