As shown in fig. 1 to 3, an embodiment of the present application provides a kiss wire, including a first guide wire 1 and a second guide wire 2, an end portion of the first guide wire 1 is provided with a first connection portion 11, an end portion of the second guide wire 2 is provided with a second connection portion 21, the first connection portion 11 and/or the second connection portion 21 have magnetism and can attract each other, and when the first connection portion 11 and the second connection portion 21 are in an attraction state, the first connection portion 11 and the second connection portion 21 are clamped. When the anastomosis guide wire is extended into a complex blood vessel vein for treatment in the embodiment, the condition that two branch blood vessels are converged at a certain position to form a main blood vessel is usually met, and when the guide wire in the prior art is used for dredging the two branch blood vessels, the guide wire is usually adopted to dredge the two branch blood vessels after being bent in the blood vessel. If the included angle between two branch vessels is small, the single guide wire can be dredged only by bending at a large angle in the vessel, so that the consumed time is long, and the vessel is easy to break.
As shown in fig. 3, when the anastomosis wire according to the present embodiment is used to open two branch vessels, the first connection portion 11 and the second connection portion 21 respectively enter the patient from the two branch vessels because the first connection portion 11 and the second connection portion 21 have magnetism. By continuously advancing the first guide wire 1 and the second guide wire 2, the first connecting portion 11 and the second connecting portion 21 are moved in the two branch vessels until the first connecting portion 11 and the second connecting portion 21 approach each other. The first connection portion 11 and the second connection portion 21 are attracted to each other by the magnetism of the first connection portion 11 and the second connection portion 21. Simultaneously first connecting portion 11 and second connecting portion 21 carry out the joint, strengthen the joint strength between first seal wire 1 and the second seal wire 2, through to the kiss seal wire with the blood vessel mediation back, can stimulate any one of first seal wire 1 or the second seal wire 2, will pull out the kiss seal wire patient internal, and it is very simple and convenient to operate, has shortened treatment time simultaneously.
Specifically, the first connection portion 11 and the second connection portion 21 may be coated with a magnetic medium layer, and the magnetic medium layer may make the first connection portion 11 and the second connection portion 21 have magnetism. If the magnetic medium layer on the first connecting portion 11 is an N pole and the magnetic medium layer on the second connecting portion 21 is an S pole, when the first connecting portion 11 and the second connecting portion 21 move to the main blood vessel where two branch blood vessels meet, the first connecting portion 11 and the second connecting portion 21 can be attracted and fixed to each other.
