How Does Lung Puncture Needle Do

The main steps of puncture under CT location are as follows. First, a chest CT scan was performed to measure the size, density, and the shortest linear distance to the skin of the mass. The number of beds was marked and the puncture site was marked on the skin. After the puncture site is anesthetized, the 18G disposable biopsy needle or semi-automatic biopsy gun is used to puncture the intrapulmonary mass through the skin, subcutaneous tissue, intercostal muscle and pleura. During this process, several scans are needed to adjust the direction and depth of the puncture needle until the tip of the puncture needle enters the edge of the mass. The patient is instructed to hold his breath and stimulate the puncture needle. Quickly pull out the puncture needle, remove the tissue for medical examination.
