| Description | This is a Sternal puncture needle, made of stainless steel. The needle features an ergonomic handle with a longitudinal anti-grip pattern. The components, which fit one into the other, include the mandrin, the arresting stick, and the adjustable front piece with a screw mechanism. The mandrin is a thin, rigid rod inserted into the hollow needle to block the lumen and prevent tissue or bone fragments from clogging it during insertion. It ensures smooth entry into the bone and allows the needle to reach the bone marrow without obstructions. Once the needle is positioned correctly, the mandrin can be removed to facilitate sample collection. The arresting stick is a safety mechanism that limits the depth of the needle's penetration into the sternum, preventing accidental over-penetration that could damage underlying structures such as blood vessels or the heart. By adjusting the arresting stick, the operator can precisely control the depth of the needle to suit the patient’s anatomy and the specific requirements of the procedure. The adjustable front piece, equipped with a screw mechanism, allows fine-tuning of the needle's length and position, ensuring correct alignment and stabilisation for optimal sampling. It also provides additional control during insertion and helps accommodate variations in patient anatomy. This instrument is designed for sternal bone marrow puncture, a critical diagnostic procedure used to evaluate bone marrow disorders, cancers, or blood-related conditions. The first sternal bone marrow puncture was performed in 1927 by Mikhail Innokentevich Arinkin who was a pioneering Russian physician known for simplifying the technique of bone marrow biopsy, making it a widely adopted diagnostic method. |
