    摘要: An insert is provided to be attached to a shield on a surgical trocar obturator handle. The insert is actuated by the surgical trocar cannula handle so that it causes the shield to expose the sharpened obturator tip after insertion of the obturator and shield within the cannula. After usage, the insert is deactivated so that the shield again covers the obturator. The obturator can then be removed from the cannula handle and obturator shield, and the obturator handle can be discarded safely.
