Introduction of Liver Biopsy Needles

May 03, 2022

Percutaneous liver puncture is based on the principle of negative pressure suction, using a rapid puncture method to extract a small amount of liver tissue from the liver, directly observe the changes in tissue morphology under a microscope, and then combine clinical data to make a diagnosis of liver disease. However, due to the small size of the obtained specimens, it is difficult to fully represent all the lesions of the liver. However, such as viral hepatitis, fatty liver, various types of liver cirrhosis, etc., the liver lesions are diffuse, so although the removed liver tissue is small, it can more accurately reflect the nature and extent of the lesions.
