What is Menghini needle?
A Menghini needle is a type of medical instrument used for performing histological and cytological biopsy. The liver is reached by inserting the needle through the skin, and a small sample of liver tissue is taken out for analysis. In order to direct the Menghini needle to the proper spot within the liver, ultrasonography imaging is frequently used. The procedure is known as ultrasound-guided liver biopsy.
Overview / Product Profile of Menghini needle:
Menghini needles are thin, hollow needles used to take tissue or cell samples from the body and examine them under a microscope. A small amount of tissue or fluid is often removed from the area of interest, such as a lump or tumour, by inserting the needle through the skin and into the area of interest. The Menghini needle is frequently employed in the diagnosis of cancers of the thyroid, breast, and lung in addition to other cancer types.
Dimensions:
Length:
Length of Menghini needle usually ranges from 12-18cm.
Outer diameter:
Outer diameter of Menghini needle is approximately 1.6 mm (0.06 inches).
Inner diameter:
Inner diameter of Menghini needle is approximately 0.8 mm (0.03 inches).
Needle tip:
Needle tip of Menghini needle is sharp and pointed.
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 Menghini needle:
Menghini needle can be used in:
1) Cysts or abscesses fluid or tissue samples aspiration.
2) Solid mass or tumour biopsies.
3) Draining of abscesses or fluid accumulation.
4) Removing dirt or foreign objects from the body
5) Injecting drugs or contrast materials during imaging tests.
6) Taking a sample of bone marrow for analysis or treatment.
7) Steroid or other anti-inflammatory drug injections are used to treat joint or soft tissue irritation.
8) Placement of catheters or other medical devices through the skin or into body cavities.
Precautions with Menghini needle:
1) Before usage, the Menghini needle should always be properly sterilised.
2) To stop the infection from spreading, use a fresh needle for every patient.
3) While using the needle, put on the proper personal protection gear, such as gloves and goggles.
4) Use the needle only as directed by the manufacturer and for the intended purpose only.
5) When using the needle, exercise caution because it is sharp and can cause harm if not handled correctly.
6) After usage, properly dispose of the needle by according to all local and federal laws regarding the disposal of sharp objects.
7) Keep children and pets away from the needle.
8) The needle must not be bent, broken, or reused.
9) When not in use, always keep the needle in its original container.
10) Do not use the needle if the packaging is damaged or if the needle is visibly damaged.
History of Menghini needle:
A specialised medical tool called a Menghini biopsy needle is used to take tissue samples from the body for testing and study. Italian radiologist Dr. Giuseppe Menghini invented the needle in the 1960s as he was looking for a less invasive and more effective approach to obtain tissue samples.
A hollow, thin-walled needle with a sharp point at one end and a handle at the other makes up the spring-loaded Menghini needle. When the spring is triggered, it pushes the needle forward, cutting through the tissue to take a sample. The needle is then placed into the tissue to be sampled. The sample is then left inside the hollow needle for analysis when the needle has been removed.
Early in the 1960s, liver and kidney samples were first obtained using the Menghini needle. But it swiftly gained popularity for the extraction of tissue samples from various additional organs, including the breast, prostate, and lung. Compared to conventional surgical biopsies, which required a wider incision and more extensive tissue removal, the needle's design allowed for a less intrusive technique.
Dr. Menghini and his team improved the Menghini needle in the 1970s by adding a built-in stylet that assisted in guiding the needle through the tissue and decreased the possibility of problems. The "Menghini-stylet" needle was created, and it became popular.
The Menghini needle also led the path for the creation of other biopsy needles, including the core needle biopsy, which has a larger, hollow core needle for collecting more samples but uses a similar spring-loaded mechanism.
Since it has been used so frequently in medical procedures for more than 50 years, the Menghini needle has established itself as a vital tool in the detection and treatment of numerous illnesses. It is a well-liked option for both diagnostic and research purposes due to its non-invasiveness and high accuracy rate.
The Menghini needle has been modified to work with many imaging modalities like ultrasound, CT, and MRI, and is now often used in hospitals and clinics all over the world. It is still a common option for the extraction of organ samples, including those from the liver, kidney, prostate, lung, and breast.
In conclusion, Menghini needle is an essential medical device that has altered the way tissue samples are obtained for diagnostic and research purposes. Since Dr. Giuseppe Menghini created it in the 1960s, different biopsy needles have been created, and it is still commonly used in modern medicine.
