Mht. Reinges et al., EXPERIENCE WITH A NEW MULTIFUNCTIONAL ARTICULATED INSTRUMENT HOLDER IN MINIMALLY INVASIVE NAVIGATED NEUROSURGERY, Minimally invasive neurosurgery, 41(3), 1998, pp. 149-151
A new multifunctional articulated instrument holder for use in minimal
ly invasive navigated neurosurgery is presented. The instrument holder
is secured to the Mayfield clamp, yielding permanent fixation and gui
dance of instruments. Thus, surgical conditions with the advantages of
both conventional and frameless stereotaxic neurosurgery are created
without sacrificing the relevant advantages of both methods. Accuracy
testing of the instrument holder in combination with the neuronavigati
on system EasyGuide Neuro demonstrated an error of 0.0 to 2.4 (mean 1.
6) mm. In clinical testing, the device has been used for guided cathet
er insertions, pointer fixation for continuous intraoperative guidance
and trajectory planning, navigated endoscopic procedures, and navigat
ed intracerebral biopsies in totally 53 patients.
