摘要：
A method for safely operating a marking apparatus includes: providing a handle, a cannula that extends from the handle, a stylet slidably received within a lumen of the cannula for movement between a ready position and an extended position, and a plunger coupled to the stylet providing a safety that comprises a channel provided on one of the handle and the plunger and a catch provided on the other of the handle and the plunger defining a safety-on position wherein the catch and the channel are rotationally misaligned defining a safety-off position wherein the catch and the channel are rotationally aligned and rotating the catch with respect to the channel to move the safety from the safety-on position to the safety-off position to permit movement of the plunger and the stylet from the ready position to the extended position to expel the imaging marker from the cannula.
