BIOPSY GUN DEVICE

摘要

PURPOSE: A biopsy gun device is provided to maintain stiffness for smoothly transferring a force to a needle and to secure flexibility with a coil tube adjacent to the needle, thereby allowing a needle and a cutting tube to accurately penetrating a target position, easily adjusting the working distance of the needle and the cutting tube, and conveniently manipulating the needle and the cutting tube. CONSTITUTION: A biopsy gun device includes a needle part (10), a main body (30), loading units (60,62), and shooting units (80,90). The needle part comprises a needle and a cutting tube. The needle penetrates a tissue for a biopsy, and the cutting tube cuts the tissue extracted by the needle. The needle part is mounted on the main body. The loading units and the shooting units are assembled in the main body so that the needle and the cutting tube are sequentially shot. The device firstly shoots the needle, and secondly shoots the cutting tube.
