Liver biopsy is a medical procedure which is done to collect tissue samples from the liver for diagnosis and monitoring of progress of liver disease. Liver biopsy can be done in 3 ways- first, percutaneously through skin, second, transvenously through blood vessels, and third, during abdominal surgery.
Two types of needles are used for percutaneous liver biopsy-
T-Lab Transjugular liver biopsy system is the latest device to perform biopsy. It contains needle with flexcore technology which adjusts according to the curvature of the sheath and can navigate easily through the tortuous anatomy of liver. The sheath has a safety funnel with which the needle can be unloaded and loaded easily without the risk of needle stick injury. The device contains swab sticks which can efficiently remove sample, while keeping the hand of the user away from the needle. There is a radio opaque band attached to the tip of the sheath which helps to visualize the location of the sheath during the procedure. Also there are red markings on the needle and introducer sheath which helps in proper alignment of the device during the procedure and a black mark on the end of the needle which helps to understand when the needle has reached the end of the sheath.
