Jamshidi Needle[edit]

A Jamshidi needle used for bone marrow biopsy.

The Jamshidi needle is a specialized medical instrument used primarily for bone marrow biopsy and bone marrow aspiration. It is named after its inventor, Dr. Khosrow Jamshidi, who developed the needle to improve the ease and accuracy of obtaining bone marrow samples.

Design and Features[edit]

The Jamshidi needle is designed to penetrate the cortical bone and access the bone marrow cavity. It typically consists of a sharp, hollow needle with a tapered tip and a handle for easy manipulation. The needle is often equipped with a stylet, which is a solid rod that fits inside the needle to prevent tissue from clogging the lumen during insertion.

Components[edit]

Needle: The main component used to penetrate the bone.
Stylet: A solid rod that prevents clogging and assists in guiding the needle.
Handle: Provides grip and control during the procedure.

Procedure[edit]

The use of a Jamshidi needle is a common procedure in hematology and oncology for diagnosing various blood disorders and cancers. The procedure involves the following steps:

Preparation: The patient is positioned appropriately, and the skin over the biopsy site is cleaned and anesthetized.
Insertion: The Jamshidi needle is inserted through the skin and into the bone, typically the iliac crest or sternum.
Aspiration/Biopsy: Once the needle is in place, the stylet is removed, and a syringe is attached to aspirate bone marrow or the needle is advanced further to obtain a core biopsy.
Removal: The needle is carefully withdrawn, and pressure is applied to the site to prevent bleeding.

Applications[edit]

The Jamshidi needle is used in various medical applications, including:

Diagnosis of Blood Disorders: Such as leukemia, lymphoma, and anemia.
Bone Marrow Transplantation: To assess the health of the bone marrow before and after transplantation.
Cancer Staging: To determine the extent of metastasis in certain cancers.

Advantages[edit]

The Jamshidi needle offers several advantages over other biopsy techniques:

Minimally Invasive: Causes less trauma compared to open surgical biopsies.
High Yield: Provides adequate samples for diagnostic purposes.
Versatile: Can be used for both aspiration and core biopsy.
