Abstract
A needle stop for a biopsy needle or the like in the form of a spring having coils in firm engagement with the surface of the shaft of the needle. Ends of the spring may be pinched to enlarge the coils and permit movement of the stop along the shaft. A guard tube is associated with the stop for covering the point of the needle when not in use.
