The Difference Between Bone Marrow Biopsy Needle And Bone Marrow Puncture Needle

Bone marrow biopsy:

Bone marrow biopsy is abbreviated to use a special puncture needle to take a small piece of cylindrical bone marrow tissue about 0.5 to 1 cm long for pathological examination. The method of operation is exactly the same as that of bone marrow puncture, and the material taken out maintains the complete bone marrow tissue structure, which can make up for the lack of bone marrow puncture.

Bone marrow biopsy:

bone puncture is to take a small amount of bone marrow for examination. Bone marrow is filled in the bone marrow cavity and bone cancellous reticulum, and it is divided into red bone marrow and yellow bone marrow. Red bone marrow has hematopoietic function, and yellow bone marrow has a lot of adipose tissue. With age, the red bone marrow in the medullary cavity is gradually replaced by yellow bone marrow. Red bone marrow is retained in the spinal canal, sternum, ribs, clavicle, scapula, iliac bone, skull, femur and the upper cancellous humerus. It is the main hematopoietic organ of the human body. Abnormal quality and quantity of blood cells are important pathological changes in hematological diseases. .
