Jamshidi needle

Jamshidi needle is a type of medical needle used primarily in biopsy procedures to extract bone marrow or bone samples for examination. Named after its inventor, Parviz Jamshidi, the needle is designed to minimize patient discomfort and reduce the risk of complications.

History

The Jamshidi needle was invented by Parviz Jamshidi, an Iranian-American physician, in the 1970s. It was designed to improve the safety and efficiency of bone marrow biopsies, which were often painful and carried a risk of complications. The needle quickly gained popularity in the medical community due to its unique design and effectiveness.

Design

The Jamshidi needle is made of stainless steel and consists of a hollow, cylindrical shaft with a sharp, beveled tip. The needle is typically 11 to 15 cm in length and comes in various diameters, depending on the specific procedure. The handle of the needle is designed for easy grip and control, allowing the physician to accurately guide the needle into the bone.

Use

The Jamshidi needle is primarily used in bone marrow biopsy procedures. The needle is inserted into the patient's bone, typically the hip or sternum, and a sample of bone marrow is extracted for examination. The needle's design allows for a clean, precise cut, minimizing patient discomfort and reducing the risk of complications.
