On structure, by the necking down endoporus and afterbody block of the front end baffle of Hafu-type shank body 18, to constrain the free degree of antenna body, it is aided with painting
Glue is fixed, followed by pommel 19 and handle tail 20 distinguish encapsulation at the cylindrical two ends of the shoulder of Hafu-type shank body 13, to be adhesively fixed.
The present embodiment has the high performance water cooling microwave ablation antenna that anti-microwave interference thermometric is integrated with microwave ablation, its
Assemble flow is still assembled for leading component, then carries out general assembly：
First, it is identical with embodiment one, first carry out the assembling of " medium tube assembly " and " water inlet component ".
In addition, by the technical requirements of temperature survey end (fusion points), welding fine copper silk temperature measuring wire 9 and Contra wire are surveyed
Warm wire 10, welding welding fine copper silk temperature measuring wire 9 ' and Contra wire temperature measuring wire 10 ', the temperature of two groups of T thermocouples are surveyed
The fusion points at end are measured, or examine T-shaped thermocouple and its temperature survey end of specialized factory's customization.And aligned on transition sleeve 17
Water inlet tap 15 (water inlet component), faucet 16 are welded and fixed, is constituted " transition sleeve component ".
After components above assembling is completed, according to the order of afterbody after first fore-end, general assembly is carried out.
The assemble sequence of the present embodiment fore-end and requirement are essentially identical with embodiment one, are not repeated, it is distinguished
It is：The present embodiment is that on the axially appropriate position of first T-shaped electric thermo-couple temperature measurement end of distance, second temperature is set up again
Measurement end is spent, therefore adds one group of speciality identical part：Second matching stub, the second bushing pipe, the second fine copper a temperature measuring wire 9 ',
Second Contra wire temperature measuring wire 10 ' and metallic screen sleeve 11 '.Therefore, the assembling main points of two groups of parts and matching requirements
It is identical and corresponding with embodiment one consistent, therefore be also not repeated.
After the assembling of the present embodiment fore-end is completed, it is proposed that carry out air-tightness and sensitivity of thermometry, bonding strength etc.
The leak detection and inspection of aspect.
Then enter the assemble flow of the present embodiment afterbody, order is as follows：
First by two water inlet pipes 7 along the inner hole wall of shank 6, and its space loading shank 6 between half just coaxial cable 3
It is interior.Again by the inner and outer conductor and the inner and outer conductor of radio frequency contact pin connector 14 of half firm coaxial cable 3, align and weld by technical requirements
Connect firmly.Fine copper silk temperature measuring wire 9, Contra wire temperature measuring wire 10, the second fine copper silk temperature measuring wire 9 ', the second cupro-nickel are closed
The tail end of four temperature measuring wires such as spun gold temperature measuring wire 10 ' aligns the installation from each thermometric line conversion terminal of transition sleeve 17 respectively
Pass, then align and each self-corresponding thermometric line conversion terminal 13 (two) and the second special switching line terminals respectively in hole
The cored wire firm welding of 13 ' (two), then loads transition by the thermometric line conversion terminal 13 ' of thermometric line conversion terminal 13 and second
The respective mounting hole of set 17, is positioned, then by the cylindrical each mounting hole with transition sleeve 17 of the shoulder of each thermometric line conversion terminal
It is welded and fixed.Then by the shoulder endoporus encapsulation of the tail end of transition sleeve 17 in the cylindrical of the horizontal end face shoulder of radio frequency contact pin connector 14
On, to be welded and fixed.Shank positioning sleeve 12 is axially loaded from antenna front ends along the outer surface of shank 6 again, by its end face shoulder
The cylindrical end face inner bore for loading transition sleeve 17, is welded and fixed, the endoporus of shank positioning sleeve 12 and shank 6 are cylindrical afterwards in place, then to weld
Connect fixation.
The assembling of the present embodiment antenna body portion is completed above.It is all to require welding part in above-mentioned assembling process, adopt
Connect with high temperature tin wire bond, there must not be rosin joint phenomenon, all weld seams must not leak or infiltration.It is all requiring bonding, recommend high temperature bonding
Agent, and carried out by its technique for sticking requirement.
With regard to this as " ablation antenna body " semi-finished product, the inspection of properties of product and technical indicator should be carried out, can be according to country
The regulation of pharmaceuticals industry standard and requirement, it is proposed that take full inspection.
It is finally glued or heat seal plastic handle.The backwater cavity segment contraposition of antenna body afterbody is first loaded on Hafu-type
In shank body 18, gluing is fixed, then second half glued Hafu-type shank body 18, and then gluing, encapsulation is distinguished by pommel 20 and handle tail 19
On the shoulder at the two ends end to end of Hafu-type shank body 18 is cylindrical, fixed with gluing.
With regard to this, terminate the assembling of the present embodiment.Hereafter, examination and test of products suggestion performs GB2828 sampling inspection.
