Description of drawings
The reader with reference to advantages after the specific embodiment of the present invention, will become apparent various aspects of the present invention.Wherein,
Fig. 1 shows the structural representation according to one aspect of the present invention microwave melt needle.
Fig. 2 shows the vertical view of the main body of handle among Fig. 1.
Fig. 3 shows the side view of the base of handle among Fig. 1.
Fig. 4 shows the flow chart according to the method for attachment of another aspect of the present invention microwave melt needle.
The specific embodiment:
With reference to the accompanying drawings, specific embodiments of the invention is done further to describe in detail.
Fig. 1 shows the structural representation according to one aspect of the present invention microwave melt needle.With reference to Fig. 1, microwave melt needle comprise melt syringe needle 10, melt needle tubing 11, handle 12.Wherein, melt syringe needle 10 and melt needle tubing 11 and be connected, and melt an end of needle tubing 11 and melt and be provided with tetrafluoro insulator 13 between the syringe needle 10, the other end that melts needle tubing 11 then is connected in the head of handle 12.Handle 12 comprises main body 14 and base 15.
Fig. 2 shows the vertical view of the main body of handle among Fig. 1.With reference to Fig. 2, the afterbody of main body 14 has socket 141 and the coaxial cable connector 142 that inserts base 15.Continuation is with reference to Fig. 1, and the upper surface of main body 14 is first plane 143, and lower surface is first cambered surface 144.
Fig. 3 shows the side view of the base of handle among Fig. 1.With reference to Fig. 3, base 15 has metal interface 151.Continuation is with reference to Fig. 1, and the upper surface of base 15 is that 152, one sides, second plane are second cambered surface 153.
Wherein, when main body 14 was inserted base 15, first plane 143 of main body 14 and first cambered surface 144 corresponded respectively to second plane 152 and second cambered surface 153 of base 15, and simultaneously, main intravital coaxial cable connector 142 is sticked in metal interface 151 just.The manufacturing materials of handle 12 can be acrylonitrile, butadiene and cinnamic synthetic plastic.In addition, the main body 14 of handle 12 forms an angle with base 15, and particularly, the scope of angle is 90 °～150 °, and more particularly, angle is 90 °.The handle 12 that has such angle, medical worker's hands when operation can feel more comfortable.In the present embodiment, the length of the socket 141 of main body 14 is 3～5mm.Because handle 12 passes through the grafting of main body 14 and base 15, therefore, can be for convenience detach.
