摘要： A coaxial bone marrow biopsy needle assembly is disclosed. The assembly includes a hollow cannula with a handle having an interlocking device and a trocar insertable in the cannula and having a second handle with another interlocking device which mates with the interlocking device in the cannula handle. The interlocking devices are a spring biased pin radially entering a receiving socket, and a notched projection which extends into the receiving socket. The pin has a ramped portion, and the notched projection has a rounded or conical tip which rides down the ramped portion of the pin and thereby pushes the biased pin radially out of the socket during assembly of the hollow cannula with the trocar. The assembled handles provides a smooth upper surface which fits comfortably in a palm and a lower gripping surface around which fingers easily wrap. The interlocking devices hold the handles securely together keeping the trocar within the cannula during puncture, but are easily separated thereafter.

摘要： An air introduction system for a medical needle assembly is provided and includes a flexible bladder, and a male luer assembly with an air valve which is biased to allow air to enter the air introduction system but not to exit. The air introduction system is coupled to a needle assembly which is to be introduced into the epidural space. As the needle traverses the tissue layers overlying the epidural space, and the practitioner applies pressure to the bladder, the practitioner experiences resistance to the forcing of air through the needle assembly. If air is lost from the bladder, the bladder may be refilled by releasing the pressure on it and allowing outside air to enter via the air valve. Once the epidural space is penetrated, air is quickly forced from the bladder through the needle assembly and the practitioner can feel a sudden drop in pressure. To aid in detection, the air introduction system is provided with an air activated sound device situated so as to be exposed to the air flow pushed out of the bladder. With the sound device, an audible warning is provided as the air rushes from the bladder through the needle assembly and into the epidural space.

摘要： The needle assembly of the present invention includes a hollow cannula having a sharp distal end, a hollow stylet having a blunt distal end with a radial opening and an interior deflection surface near the radial opening, and a mechanism for biasing the stylet in a first position where the blunt distal end of the stylet extends beyond the sharp distal end of the cannula. Preferably, the hollow cannula hub has a proximal end which is coupled, e.g., via insert molding, to a hollow cannula hub. Likewise, the stylet preferably includes a proximal end which is coupled, e.g., via insert molding, to a hollow stylet hub which is longitudinally movable within the hollow cannula hub. The mechanism for biasing typically comprises a spring inside the cannula hub which biases the stylet hub to the first position where the blunt distal end of the stylet extends beyond the sharp distal end of the cannula. The stylet is movable against the spring to a second position where the sharp distal end of the cannula extends beyond the blunt distal end of the stylet. A first indicator is provided on the cannula hub showing the position of the stylet relative to the cannula and a cannular orientation indictor on the cannula shows the direction of the radial opening.
