| Description | This is a Salah's bone marrow needle, made of stainless steel and brass. The needle features an ergonomic handle with a flattened design and an engraved "S." It consists of several components that fit together: 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 prevent tissue or bone fragments from clogging it during insertion. It acts as a depth guard, ensuring smooth entry into the bone and allowing the needle to reach the bone marrow without obstructions. Once the needle is correctly positioned, the mandrin is removed to collect the sample. The arresting stick is a safety mechanism that controls how deep the needle penetrates into the sternum. This prevents accidental over-penetration that could harm nearby structures like blood vessels or the heart. Adjusting the arresting stick ensures the needle’s depth matches the patient’s anatomy and the needs of the procedure. The adjustable front piece, equipped with a screw mechanism, allows fine-tuning of the needle's length and position. This ensures proper alignment, stability, and control during sampling, accommodating differences in patient anatomy. This needle is specifically designed for infusion and trasfusion, and monitoring patients with cancer receiving treatment. 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. |
