This invention relates to a universal catheter for accessing visceral arteries via the radial artery, belonging to the field of medical device technology. The catheter is hook-shaped and comprises, on the same plane, a first straight segment, a first curved segment, a second straight segment, a second curved segment, a third straight segment, a third curved segment, and a straight head segment arranged sequentially from the end closest to the operator, with the straight head segment facing the beginning of the catheter. The specialized catheter provided by this invention increases the catheter's curvature, resulting in better stability after insertion into the target vessel; it also has better torque transmission capability, good maneuverability, and makes it easier to reach the target location within the blood vessel, shortening the operation time and increasing the success rate of the surgery.
