摘要:
A surgical assembly for marking a tumor includes a surgical instrument and an elongated tissue marker. The surgical instrument includes an ultrasonic probe and a needle configured to move in a distal direction through a channel of the ultrasonic probe from a retracted position to a deployed position. The tissue marker is disposed within the needle and deployable therefrom. The tissue marker includes a distal portion and a plurality of fixation elements coupled to the distal portion. Upon deployment of the tissue marker from the needle, the plurality of fixations elements are configured to move from a collapsed configuration to an expanded configuration to anchor in a tumor.
