1. A hollow endodontic instrument (10) for shaping and simultaneous flushing and suctioning a tooth root canal comprising:
a) an inner spicular passage (200) for delivering an irrigation solution,
b) a hollow elongated mesh-like structure (100) for shaping a tooth root canal containing an active part and a coronal part, surrounding the inner spicular passage (200), and the active part protruding over the length of the inner spicular passage (200), and
c) a suction element (300) forming at least one outer passage for sucking the irrigation solution surrounding the inner spicular passage (200),
wherein the inner spicular passage (200) is insertable into the tooth root canal, and wherein the suction element (300) surrounds at least a portion of the hollow elongated mesh-like structure (100) and/or is located in the coronal part of the hollow elongated mesh-like structure (100), and
wherein the active part of the hollow elongated mesh-like structure (100) for shaping a tooth root canal comprises longitudinal elements (110) and circumferential elements (120) that connect adjacent longitudinal elements (110).
