Abstract: A novel biopsy needle like surgical instrument to obtain both solid bone marrow biopsy and liquid bone marrow aspirate by a new method of obtaining both specimens in a single procedure are disclosed. The needle consists of two heads at the proximal end, two lumina inside its elongated body and two distal openings. Each head contains portal for entry for respective stylets for biopsy and aspiration. The distal end of the needle contains two openings leading to the lumina inside the needle meant for biopsy and aspiration respectively. The proximal one third of the needle is encased in a specially designed handle with grips for the index finger, the thumb and a cap for the hollow of the operators hand.Upon insertion of the needle in the cortical bone of the iliac crest of the patient the biopsy stylet is withdrawn. Further pushing the needle results in entry of the marrow cavity facilitating entry of a solid core of marrow in the hollow biopsy portion of needle lumen.

Abstract: An assembly of built-in dual system for rapidly stabilizing and firmly securing an intravascular needle or catheter like instrument to a patient is disclosed. One portion of the system consists of a roll of adhesive tape fixed strategically in a wing like structure on each side of the needle or catheter. The second system is composed of built-in suction cups undersurface of a wing like structure on each side of the needle or catheter. Upon insertion of the needle, in a blood vessel of a patient, merely dabbing the wings of the catheter to the skin extrudes air out of the suction cups. Thus vacuum created causes the suction cups to cling to the skin immediately due to atmospheric pressure. As a result the wings and the needle are stabilized immediately. This frees the hands of the operator to uncoil the adhesive tape roll provided with a clip and handle device for easy grip. Each wing is taped down firmly to the skin, achieving permanent securement to the patient.
