What is the bone marrow needle?

The bone marrow needle is a device used in bone marrow transplantation, which is a procedure used in a range of treatment for some serious health conditions. Aplastic anemia, some disorders and cancer of immune deficiency, such as Hodgkin's disease and leukemia, are sometimes treated by bone marrow transplantation. The first step is to use the bone marrow needle to remove the bone marrow from the donor, which in some cases can also be a patient.

The bone marrow needle differs from other types of needles in several ways. Unlike many medical needles, most of which are used for injections, the bone marrow needle is used for something. These needles have structural functions that allow them to perform this important medical procedure. First, bone marrow needles stronger than the average hypodermic needle, which is usually 12 meters. Most hypodermic needles are smaller, usually at least 16 breakups.

Both types of needles are used with syringes. Syringe used with bone marrow needle normallyE significantly larger in capacity, because up to two liters (1.9 liters) bone marrow and blood can be extracted from a donor or patient. The syringe for the bone marrow needle is also usually connected after inserting the needle rather than before inserting the needle.

bone marrow needles usually have a handle that is very different from other types of needles. There are different patterns from different manufacturers, but most of them have a hard handle that gives doctors the grip and lever needed to force the tip of the needle to the bone. Needles also have a special removable inner part called trochar. This is removed after insertion to allow removal of the marrow, a process called bone marrow aspiration.

Sometimes a small amount of bone marrow is to be extract for a sample called biopsy, and for this PR is used the same type of needle is used. During the bone marrow biopsy, the trochar is not removed and the small core of the bone and the pulp is captured in the needle. This sample is then used for various medical tests whose results are useful in testing potential donors.
