A surgical needle including a cannula, hook-wire and reinforcement member for use in the manual location and marking of a lesion in a mass of soft tissue. The cannula rigidly supports the hook-wire during insertion into the soft tissue, and has a substantially cylindrical, hollow shaft and a cutting point located at an insertion end. The surgical needle further includes an anchor for restrainably locating the hook-wire proximate the lesion which is capable of springedly assuming a substantially acute angle relative to the remainder of the hook-wire. Reinforcement minimizes the potential for breakage of the hook-wire within the mass of soft tissue, after extension of the hook-wire beyond the insertion end of the cannula; in which the hook-wire is substantially D-shaped and closely approximates the diameter of the substantially cylindrical, hollow shaft; maximizing the structural size and integrity of the hook-wire to minimize the occurrence of breakage.
