Specific embodiment
As shown in figure 1, microwave melt needle includes：Needle point body 1, shank 2, microwave coaxial connector 6, handle 7, water inlet pipe 8,
Outlet pipe 9, through there is a microwave coaxial cable 10 in shank 2, one end of the microwave coaxial cable 10 is connected with microwave coaxial
Device 6 is connected, and the water inlet pipe 8 and outlet pipe 9 are fixed on the handle 7.The first implementation method as shown in Figure 2,3, its
In, the material of needle point body 1 is ceramic body, and needle point body 1 is internally formed hollow space, in the needle tip wall of needle point body end section 3
Thinning, the needle tip wall of needle point body end section 3 forms depression due to the different of thickness from the needle tip wall of the fore-end of needle point body 1
4, the end section 3 that shank 2 prolongs the needle point body is inserted, and the front end of shank 2 is arrived at depression 4, the inwall of shank 2 and needle point body tail end
The gap filling seccotine 301 divided between 3 needle tip wall outside is bonded.The other end insertion of the microwave coaxial cable 10
The hollow space of needle point body 1, the gap between the outer wall of microwave coaxial cable 10 and the needle tip wall inner side of needle point body end section 3
Also filling seccotine 301 is bonded.One or more are opened in the needle tip wall of needle point body end section 3 through whole needle point body
The through hole 5 of the needle tip wall of end section 3, when needle point body end section 3 and shank 2 and microwave coaxial cable 10 are bonded,
One or more through holes 5 are also stuffed entirely with by seccotine 301.Wherein, the material of shank 2 can be stainless steel.
In second implementation method, remaining part in addition to needle point body 1 of microwave melt needle and assembling bonding
Mode is identical with the first implementation method, will not be repeated here.The difference of second implementation method and the first implementation method
It is only that, the structure of needle point body 1 is made up of T-shaped needle body 11 and the two parts of ceramic body 12, as shown in Figure 4.Wherein, T-shaped needle body 11
Material be high duty metal, the inner wire of the T-shaped needle body 11 and the microwave coaxial cable 10 of the hollow space of insertion needle point body 1
It is connected.
In the middle of actual operation, whole pin is run through due to there are one or more in the needle tip wall of needle point body end section 3
The through hole 5 of the needle tip wall of sharp body end section 3 is strong between making on the outside of the needle tip wall of the inwall of shank 2 and needle point body end section 3
Power glue 301, the outer wall of the seccotine 301 being filled among through hole 5 and microwave coaxial cable 10 and needle point body end section 3
Needle tip wall inner side between seccotine 301 constitute a seccotine glued construction for I-shaped, this significantly improves needle point
Bonding strength between the microwave coaxial cable 10 of body 1 and shank 2 and the hollow space of insertion needle point body 1, greatly reduces microwave
When ablation needle is extracted from patient's body, the risk that needle point body 1 comes off and stays in patient's body.
As shown in figure 5, microwave melt needle of the invention is within the shank 2 in addition to needle point body 1, except through there is a microwave
A cooling tube 13 is also extended through outside coaxial cable 10, the cooling tube 13 is enclosed within outside microwave coaxial cable 10, is fixed on shank 2
Between microwave coaxial cable 10.For to microwave melt needle rise cooling effect water by the water inlet pipe 8 (not shown in Fig. 5,
Shown in Fig. 1) and gap between the inwall of cooling tube 13 and the outer wall of microwave coaxial cable 10 in flow into, by cooling tube 13
Outer wall and the inwall of shank 2 between gap in and the outlet pipe 9 (not shown in Fig. 5, being shown in Fig. 1) outflow, from
And realize the cooling water circulation of microwave melt needle.The material of the cooling tube 13 can be stainless steel.
