ABSTRACT:
Needle for bone marrow biopsies including a cannula, a cannula housing supporting the cannula including a partially threaded lower member, a stylet including a stylet cap supporting the stylet and a threaded depth stop for engaging over the cannula wherein the stylet engages into the cannula in a predetermined relationship, the stylet cap interlocks to the cannula housing, and the threaded member determines the depth of penetration of the needle. The sternum needle is constructed to be either disposable or reusable depending upon the cannula housing and stylet cap material. The cannula housing includes vertical wings extending outwardly from the housing for engagement with the palm of a physician's hand, a cannula clip having ends which are soldered onto the cannula and secure into the cannula housing, and an elongated button extending outwardly from the top of the cannula housing for detent locking with the stylet cap providing for alignment of the stylet to the cannula of the sternum needle. The stylet includes a longitudinal member having a ground and buffed beveled end maintaining a knife-sharp edge around the tip, and the other end of the stylet is bent and molded into the stylet cap where the stylet cap includes a spring detent locking groove for interlocking with the button of the cannula housing. The stylet cap is rounded at the top and includes vertical grooves for gripping during locking and unlocking.
