A biopsy assembly with an inner stylet having a needle end with a biopsy retrieval recess on the needle end. At the other end of the stylet is a hub for controlling the needle. A hollow outer needle with a main hub at the proximal end carries the inner needle in a sliding relationship. Releasable latch means are provided on the respective hubs to lock them in a fixed but releasable axial position which makes it possible for a physician to enter the spaced hubs in a cocked biopsy gun.
