Applikator für inplantierbaren chirurgischen Marker

摘要

An applier (30) for delivering and deploying a biopsy marker (31) to a surgical biopsy site is disclosed. The applier (30) has a ferrule (34) with a forming surface to form the marker (31) on the distal end of a flexible tube. The marker (31) is held at the distal end of the flexible tube in a marker holder (32). A forming rod slidable in the flexible tube urges the marker (31) into contact with the forming surface of the ferrule (34) for marker formation. The distal end of the flexible tube is delivered through an egress tube (63), which in turn is delivered through a biopsy cannula (73) adapted for taking the biopsy sample. The egress tube (63) has an alignment hub (66) at its proximal end adapted for orientational alignment with a hub receiver (75) on the biopsy cannula. When properly aligned, the egress opening (64) of the distal end of the egress tube (63) is orientationally aligned with the biopsy port (74) of the biopsy cannula (73) for proper delivery and deployment of the marker (31).
