Ultra-fine micropsy needle

摘要

A specimen retrieving needle is in the form of an elongated body having a closed lead end. At least one cutting blade may be formed on the body. The blade may have a sharpened edge so as to remove a specimen from an internal organ. The needle is ultrathin with an outside diameter of less than 1.0 mm to minimize tissue trauma and to reduce the risk of pain, hemorrhage and organ damage.
