    • 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.
    • 根据本发明的一个实施例的标记装置包括手柄,具有插管远端并可滑动地安装到手柄的插管,以及具有探针末端并且可滑动地安装到套管中的手柄的探针。 探针远端在套管远端的近侧间隔开,以形成接收成像标记的标记凹部。 标记装置还包括可操作地耦合到套管的致动器,以在植入成像标记物之后实现套管到手柄中的缩回。 可以通过相对于套管前进探针来植入成像标记物,以从标记凹槽喷射成像标记物,或者插管可以相对于管心针缩回以暴露成像标记。
