What is Jamshidi needle (Bone marrow needle)?
The Jamshidi needle (Bone marrow needle) is a trephine needle used in medical procedures to obtain a sample of tissue or bone marrow, which yields a cylindrical sample of tissue.
Overview / Product Profile of Jamshidi needle:
Jamshidi needles are frequently made up of stainless steel which have a sharp, pointed tip used for puncturing bone. Additionally, the needle features a hollow centre that enables the suction of bone marrow cells for analysis. Under local anaesthetic, the needle is often placed into the bone while being guided by imaging methods like x-ray or ultrasound.
Dimensions:
Length:
Jamshidi needle's length usually ranges from 8 cm to 20 cm.
Diameter:
Jamshidi needle's diameter typically ranges from 0.8 mm to 1.6 mm.
Handle:
Jamshidi needle's handle may be made of plastic or metal and is used to grip and manipulate the needle.
Point:
Jamshidi needle's point may be sharp or blunt depending on the intended use.
Shaft:
Shaft of Jamshidi needle is long, thin portion of the needle that connects the handle to the point.
Taper:
Jamshidi needle has gradual decrease in diameter from the handle to the point
Eye:
The small hole near the point of the jamshidi needle is used for threading or passing fluids through.
Material:
Jamshidi needle may be made of stainless steel, titanium, or other materials.
Note: The above dimensions may vary slightly depending on the manufacturer and specific design of the instrument. It's always advisable to consult with the manufacturer's specifications and guidance for accurate measurements.
Uses of Jamshidi needle:
1) Collecting a sample(Aspiration) of bone marrow for testing and treatment.
2) Biopsy of bone and soft tissue tumors.
3) Medicine or contrast agent injections into bones or joints.
4) Getting rid of calcifications or foreign objects from joints or bones.
5) Removal of fluid buildups or abscesses from joints or bones.
6) Placing pacemaker leads or central venous catheters through the bone.
7) Vertebroplasty and kyphoplasty are examples of vertebral augmentation surgeries.
8) Implantation of a urethral stent with a percutaneous nephrostomy.
9) Placement of percutaneous tracheostomy, gastrostomy, and jejunostomy tubes.
Precautions with Jamshidi needle:
1) Before using a needle, always make sure it has been adequately sterilised.
2) To guard against any potential exposure to blood or other bodily fluids, use the proper personal protective equipment (PPE), such as gloves, goggles, and a face mask.
3) When inserting the needle, exercise cautious to prevent piercing any important blood vessels or organs.
4) Observe the depth and angle recommendations for the particular portion of the body being aspirated.
5) To identify the area of the body being aspirated, use a method of marking that is distinct and easy to see.
6) After the procedure, keep an eye on the patient for any indications of complications or negative responses.
7) After usage, carefully dispose of the needle in a sharps container.
8) Prior to use, always inspect the needle for any signs of wear or flaws.
9) Use appropriate sedation or anesthesia if necessary to reduce pain and discomfort for the patient.
10) Always follow the guidelines and regulations set forth by your facility when using Jamshidi needles.
History of Jamshidi needle:
The Jamshidi needle, also referred to as the Jamshidi bone marrow biopsy needle, is an instrument used in medicine to remove bone marrow samples for both diagnostic and therapeutic purposes. Dr. Kambiz Jamshidi, an Iranian-American physician and researcher, created the needle for the first time in the early 1980s while he was employed at the Memorial Sloan-Kettering Cancer Center in New York City.
Dr. Jamshidi wanted to develop a bone marrow biopsy needle that would be less intrusive and more effective than the ones that were currently in use. He started by experimenting with various materials, such as plastic and stainless steel, before deciding on a design that made use of a hollow, spring-loaded steel needle.
Early in the 1980s, the Jamshidi needle's initial prototype was tested on patients and revealed to be substantially less painful and more effective than conventional bone marrow biopsy needles. A bigger sample may be taken with less harm to the surrounding tissue thanks to the needle's design.
Dr. Jamshidi registered a patent for his needle in 1984, and his business, Jamshidi Medical Instruments, started producing and selling it. By the 1990s, the needle had established itself as the go-to instrument for bone marrow biopsies after fast gaining acceptance among physicians and medical facilities.
The Jamshidi needle has undergone a number of changes and adjustments over time, including the development of a disposable model for greater safety and usability and the addition of a safety mechanism to avoid unintentional needle sticks.
Today, a variety of medical illnesses, including cancer, blood disorders, and bone marrow diseases, are diagnosed and treated using the Jamshidi needle in hospitals and clinics all over the world. The needle has significantly increased the accuracy and patient comfort of the bone marrow biopsy operation, and is largely regarded as a major achievement in the profession.
The Jamshidi needle, which was created by Dr. Jamshidi and died in 2018, continues to be a crucial medical tool. Dr. Jamshidi got several prizes and plaudits for his services to the medical industry.
