Chirurgische Nadel und Nadelsatz zum Zwecke der Lokalisierung.

摘要

A localisation needle assembly (10) includes an outer tubular cannula (11) and a reinforced needle structure (12) slidably mounted for movement within the outer cannula between extended and retracted portions, the needle structure defining a rearwardly extending barb (13) which is contained within the outer cannula when the inner needle is extended while the surgeon locates a lesion. When the inner needle is retracted, the barb is deployed through an opening (14) in the sidewall of the outer cannula for anchoring the localisation needle assembly in body tissue in the proximity of the lesion.
