Abstract
This application relates to the field of interventional surgery for liver cancer and discloses a novel catheter for interventional surgery of liver cancer via the radial artery approach. The catheter includes a connector and two adjusting tubes. The top of the connector is connected to a connecting tube, and one end of the connector is connected to an insertion tube. The center of the insertion tube and the center of the connector are on the same straight line. Several control frames are fixedly installed on the surface of the adjusting tube, and an installation groove is formed in the inner wall of the adjusting tube. One end of each of the two adjusting tubes is fixedly connected to a connecting frame. The inner wall of the installation groove engages with the surface of the insertion tube, and the dimensions of the inner wall of the installation groove are compatible with the dimensions of the insertion tube surface. This application connects the installation grooves in the two adjusting tubes to the surface of the insertion tube, and the control frames are installed on the surface of the adjusting tubes. The two adjusting frames are connected by connecting frames, so that after the entire catheter is removed from the packaging bag, the surface of the insertion tube can be covered by the adjusting tubes, and the adjusting tubes can be easily retracted by moving the control frames.
