Fast exchanging imbedding device with smaller wave pipe

The invention discloses a fast exchanging imbedding device with a smaller wave pipe. The fast exchanging imbedding device with the smaller wave pipe comprises an outer pipe, one end of the outer pipe is provided with a sharp pipe, and the other end of the outer pipe is provided with a front handle. The wave pipe is embedded into the outer pipe. The position, corresponding to the wave pipe, of the outer pipe is provided with a guiding groove, a channel for a zebra wire to penetrate through is formed from the guiding groove to the center of the sharp pipe, and the channel is internally provided with an inner pipe with the diameter larger than that of the zebra wire. The inner pipe is thinner, the external diameter of the inner pipe can be reduced to 1.1 mm from the original 1.3 mm, the external diameter of a liner channel fast exchanging imbedding device can be reduced to smaller 7F from the original 8F, and a fast exchanging liner channel support on the market at present only can be reduced to 8F. Due to the fact that the inner pipe is the stainless steel wave pipe, the tail end infusion function is achieved.
