More reliable hypotube fast switching and imbedding device

The invention discloses a more reliable hypotube fast switching and imbedding device which comprises an outer tube. A tip tube is arranged at one end of the outer tube, a front handle is arranged at the other end of the outer tube, an inner tube is nested in the outer tube, a hypotube is nested in the inner tube, corresponding parts of the outer tube, corresponding parts of the inner tube and corresponding parts of the hypotube are provided with guide grooves, channels for allowing zebra guide wires to penetrate through are formed by extending from the guide grooves to the center of the tip tube, guide tubes with the diameter larger than that of the zebra guide wires are arranged in the channels, and one end of each guide tube stretches out of the corresponding guide groove. According to the more reliable hypotube fast switching and imbedding device, due to the fact that the dedicated guide tubes are used for guiding, it is guaranteed that the zebra guide wires can penetrate out of the inner tube and the outer tube thoroughly, and the demands of fast switching are met. Due to the fact that the hypotube is engraved by using lasers, the consistency and the stability of the hypotube can be controlled completely, and manufacturability is good. Meanwhile, according to using situations of imbedding devices at different positions, lasers can be adjusted for engraving patterns, and therefore the design requirements of the imbedding devices at different positions can be met easily. Meanwhile, the tail end of the more reliable hypotube fast switching and imbedding device supports a transfusion function.
