摘要:
The invention relates to a method for navigation during medical interventions on tubular organ structures, characterized in that, before the intervention, static image data of the tubular organ structures are recorded and stored, the tubular organ structures are extracted from the image data and their course is converted into a geometric description used during the medical intervention for instrument/organ recording, and the instrument that is spatially localized by a tracking system is successively corrected in relation to the static data, by a transformation that is preferably defined by an optimization method, taking into account the geometric description and information on the previous distance covered by the instrument, or, conversely, the static data are successively corrected in relation to the instrument position, and thus the position of the instrument is associated with the anatomical structures in the static image data.
摘要:
The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.
摘要:
A clip or flexible handles extension facilitate simultaneous retention and operation of a bronchoscope and associated bronchoscopic tools held in one hand to allow operation by a single practitioner. Also provided is an adapter for the connection port of the working channel of a bronchoscope which performs both sealing and tool-locking functions. Also disclosed is a guide sheath arrangement with a reduced flexibility proximal portion to facilitate insertion of tools into the guide sheath.
