摘要：
A marking device according to one embodiment of the invention comprises a handle, a cannula having a cannula distal end and slidably mounted to the handle, and a stylet having a stylet distal end and slidably mounted to the handle in the cannula. The stylet distal end is spaced proximally of the cannula distal end to form a marker recess that receives an imaging marker. The marking device further comprises an actuator operably coupled to the cannula to effect retraction of the cannula into the handle following implantation of the imaging marker. The imaging marker can be implanted by advancing the stylet relative to the cannula to eject the imaging marker from the marker recess, or the cannula can be retracted relative to the stylet to expose the imaging marker.
