ABSTRACT OF THE DISCLOSURE The trocar is provided with a leaf spring in the housing which abuts a collar on a protective tube which surrounds the sharp tip of the stylet. A spring finger extending from the leaf spring is actuated by a slider when the two housings of the trocar components are squeezed together. The spring finger initially lifts the leaf spring from the collar to release the protective tube for sliding proximally while the collar subsequently lifts the spring finger from the shoulder of the slider to prevent a re-release of the leaf spring when the protective tube 16 is moved back into the extended position.
