How does the liver puncture needle operate? Are there any scars?

Liver puncture is a method in which a puncture needle is inserted percutaneous into the liver and a small amount of liver tissue is removed for histological examination. The patient was placed in a supine position during puncture, and the operator generally took samples from the right intercostal needle. This method is also known as the one-second liver biopsy, which means the procedure can be completed in one second. Although it is an invasive procedure, the patient suffers little pain and damage to the liver is minimal, and the liver recovers quickly. As long as the medical routine is strictly followed, the operation is quite safe. They usually leave no scars.
