The present invention provides a guide skin expansion device and its application, which includes a clamp body. The clamp body is a clamp-like structure formed by a left clamp arm and a right clamp arm that are hinged by a pin after crossing. The front end face of the left clamp arm is connected to a left limb extending forward, and the front end face of the right clamp arm is connected to a right limb extending forward. The free ends of the left limb and the right limb overlap to form a guide head for penetrating a skin opening and for allowing a guide wire to pass through. The clamp body has an open state and a closed state. The guide skin expansion device is divided into a guide section, an expansion section, and a handheld section. The guide section guides the guide head. On the one hand, the guide wire can pass through the guide head, that is, guide the guide wire. On the other hand, the guide head can penetrate the skin opening to prepare for the next step of expansion. The expansion section is composed of a left limb and a right limb. When the guide head penetrates the skin opening, the left limb and the right limb are separated, and then the jaws are opened. The jaws can expand and expand the skin opening, and the cannula can enter the blood vessel through the expanded skin opening, which is convenient for promotion and use.
