Non-vascular orifice guide wire

Abstract

The utility model relates to the technical field of medical equipment, in particular to a non-vascular orifice guide wire which comprises a core wire, a sheath, a winding wire, a sealing ring and a plurality of developing rings, the sheath is provided with a containing cavity used for containing the core wire, the core wire is embedded in the containing cavity of the sheath, the winding wire is elastic and is wound on the core wire, and the developing rings are arranged on the sealing ring. The winding wire is located between the sheath and the core wire, a mounting groove is formed in the peripheral wall of the sheath, the developing ring and the sealing ring have elasticity, the developing ring is arranged on the sheath in a sleeving mode, the developing ring can move in the axial direction of the mounting groove, the developing ring is located in the mounting groove, the sealing ring is matched with the mounting groove, the sheath is sleeved with the sealing ring, and the sealing ring is located in the mounting groove. The developing rings are wrapped by the sealing ring, the developing part is designed to be of a developing ring structure, the developing part is installed on the outer side of the sheath in a sleeving mode, therefore, the positions of the developing rings can be adjusted, the distance between every two adjacent developing rings can be changed, and adjustment can be conducted according to the size of a focus.
