A surgical apparatus for securing a needle extending therethrough includes a post having a channel therein mounted to a base. The post is positioned in operative alignment with the needle mounted on the base. A locking member is associated with the post in operative alignment with the needle. The locking member defines an opening therethrough to receive the needle, and the locking member is operable between a needle receiving position wherein the needle may be inserted or removed from the locking member and a needle retaining position wherein the needle is retained in at least one direction of movement. A method for surgically localizing and removing tissue includes the steps of providing a tissue cutting member mounted on a base and defining an opening near a distal end, the tissue cutting member further forming a tissue receiving cavity in communication with the opening, a needle disposed within the cavity and defining a longitudinal passageway therethrough, a post mounted on the base and a locking member mounted on the post and defining having a needle receiving opening in operative alignment with the needle, the locking member being operable between a needle receiving position wherein the needle may be inserted or removed from the locking member and a needle retaining position wherein the needle is retained in at least one direction of movement, locking the needle within the locking member by rotating the locking member into the needle retaining position, positioning the needle within target tissue, severing the tissue to be removed and removing the severed tissue from a patient.

[ What is claimed is:] [1.] A surgical apparatus for localizing tissue, which comprises:a needle defining a longitudinal passageway therethrough;tissue marker disposed within the longitudinal passageway; anda marker deploying mechanism which includes an actuator operatively connected to the tissue marker, such that a predetermined amount of movement of the actuator in one direction effectuates movement of the marker to a deployed position and first orientation disposed outside the longitudinal passageway and continued movement of the actuator in the same direction to a second position causes a reorientation of the marker to a second orientation different from the first orientation.
