摘要

Instrument for performing biopsies supported organ tissues that are to be analyzed, of the type comprising a syringe essentially constituted by an outer cylindrical body, connected at one end to an optical probe and a piston received slidably in said outer cylindrical body, with creating a camera. aspiration, and having, at one end, a mandrel that slides with clearance within said optics cannula, characterized in that it comprises a pair of opposing longitudinal guides obtained in the outer cylindrical body, a gripping of said plunger, which member slides on said guides, a body of travel stop located at a recordable position in the outer cylindrical body and adapted to collide against said catcher piston, it said mandrel comprising a hollow needle creates being a path of air that flows inside the suction chamber through a hole provided inside the plunger.
