Specific implementation mode
The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment
Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
The every other embodiment that art personnel are obtained without making creative work belongs to the model that the present invention protects
It encloses.
As illustrated in fig. 1 and 2, a kind of elongated microwave melt needle, including syringe needle 1, PVC needle tubings 2 and handle 3, syringe needle 1 and PVC
One end of needle tubing 2 couples, and the other end of PVC needle tubings 2 couples with handle 3, and handle 3 is equipped with refrigerant pipe 4, and refrigerant pipe 4 is equipped with
The shape of coupling arrangement 5, handle 3 is ellipse.Refrigerant pipe 4 include water inlet pipe 41 and outlet pipe 42, cooling water can by into
Water pipe 41 is flowed out by PVC needle tubings 2 through outlet pipe 42 again.The cross sectional shape of handle 3 is ellipse, convenient for hand-held.The tool of ablation needle
Construction in the prior art may be used in body internal structure.
PVC needle tubings 2 are made of PVC material, PVC needle tubings 2（Including needle portion）Length be 1300 millimeters or
1500 millimeters, certainly, specific length can be adjusted according to actual conditions.
As seen in figures 3-5, coupling arrangement 5 is mainly used for refrigerant pipe 4 being connected to equipment, ensures the normal of cooling water
Circulation.Coupling arrangement 5 is arranged in the end of refrigerant pipe 4, and is connected to refrigerant pipe 4.Coupling arrangement 5 includes connecting tube 6 and sets
Set the moveable threaded sleeve 7 in connecting tube 6, the nozzle of equipment end is connected to by when use with 6 grafting of connecting tube, is led to after grafting
Crossing rotation threaded sleeve 7 makes the nozzle of equipment end couple with connecting tube 6 closely, avoids the generation of pull-off phenomenon.Connecting tube 6, spiral shell
Line casing 7 and the nozzle of equipment end are all made of structure in the prior art, i.e. threaded sleeve 7 joins with the sliding of connecting tube 6
