摘要:
System (600) includes imaging system (5) and the optical fiber (29) connected to fiber (25) via optical connector (58). The fiber (25) is operatively associated with a syringe (51) and passes through the bore of the needle (52). A holder (612) is associated with the syringe (51) by the syringe barrel (614). A feedback unit (620) can be associated with the holder (612).
