The invention discloses a needle-shaped minimally invasive interventional duct-inserting device for cholangiopancreatography and belongs to the technical field of medical instruments. The needle-shaped minimally invasive interventional duct-inserting device mainly comprises a novel needle-shaped knife main body, a guide wire propelling unit and a foot-controlled washing unit. The novel needle-shaped knife main body comprises a propelling rod, a handle, an electrode plug and a multi-cavity duct. The multi-cavity duct comprises a guide wire cavity inlet, a washing liquid cavity inlet, a radiography liquid cavity inlet, a guide wire cavity, a knife wire cavity, a radiography liquid cavity and a washing liquid cavity. Guide wires penetrate into the guide wire cavity, knife wires are arranged in the knife wire cavity, and a knife wire clamping head is arranged at the remote end of the knife wire cavity; and the guide wire propelling unit is arranged on the outer guide wires in a penetrating and sleeved mode, and the foot-controlled washing unit is connected with the washing liquid cavity inlet. In short, the needle-shaped minimally invasive interventional duct-inserting device for cholangiopancreatography is simple in structure, convenient to use, high in duct-inserting success rate, small in damage and low in complication occurrence rate.
