Bone marrow harvest needles are specialized medical instruments designed for the extraction of bone marrow from the donor's pelvic bones or sternum. These needles are typically used in procedures aimed at collecting bone marrow for transplantation, research, or diagnostic purposes. They come in various sizes and designs, but commonly consist of a hollow, sharp needle attached to a handle or syringe for controlled insertion and aspiration. The needles are crafted to penetrate the hard outer layer of bone and reach the spongy inner tissue where the marrow is located. During the harvesting process, medical professionals carefully maneuver the needle into the bone, applying controlled pressure to avoid damage to surrounding structures and ensure optimal marrow retrieval. Once in position, the marrow is extracted through gentle suction or aspiration into a collection device for further processing or transplantation. Advanced designs may incorporate features such as multiple side ports or adjustable depth stops to enhance efficiency and precision during the procedure. Overall, bone marrow harvest needles play a crucial role in facilitating the extraction of this vital tissue for therapeutic and investigative purposes, contributing to advancements in medical treatment and research.
