The corresponding cold head 10 of seal wire 11 stretches and arranges.
It is provided with the guiding main channel 24 of plug-in mounting seal wire 11 in coolant return-air and silk guide passage pipe 8.
The left end from guiding main channel 24 for seal wire 11 left end is exposed to the external world or arranges in coolant return-air and silk guide passage pipe 8
There is right-hand member with the guiding by-pass 25 that connect of guiding main channel 24 and seal wire 11 passes through and guides by-pass 25.
Be fitted with coolant delivery pipe 2 in coolant return-air and silk guide passage pipe 8, coolant delivery pipe 2 right-hand member be provided with
The corresponding throttle orifice 23 of cold head 10, is provided with inlet channel 22 in coolant delivery pipe 2, coolant delivery pipe 2 lateral wall with cold
Form return gas channel 21, return gas channel 21 passes through throttle orifice 23 and inlet channel between matchmaker's return-air and silk guide passage pipe 8 medial wall
22 connections.
It is set with seal wire entrance guide pin bushing 7 in coolant return-air and silk guide passage pipe 8 left part；Coolant return-air and silk guide passage pipe 8
It is installed in the main through hole 18 of seal wire entrance guide pin bushing 7；By-pass prot 19 is provided with coolant return-air and silk guide passage pipe 8, bypass
Hole 19 is connected with guiding main channel 24, and seal wire 11 passes through by-pass prot 19.
It is provided with probe insert 3 in the left positioning spigot 20 of seal wire entrance guide pin bushing 7 left end, right-hand member in probe insert 3
Screwed hole 15 in be provided with locking swivel nut 5, be provided with the core 4 that rises in locking swivel nut 5, set between core 4 in locking swivel nut 5 and rising
It is equipped with the gap 16 that is fixedly clamped, the left end of coolant return-air and silk guide passage pipe 8 is arranged on and is fixedly clamped in gap 16.
The right-hand member of probe insert 3 is provided with retainer ring 6, retainer ring 6 is sleeved on seal wire entrance guide pin bushing 7 left end and uses spiral shell
Nail connects.
It is provided with the first endoporus 13 in probe insert 3, be provided with second between the first endoporus 13 and screwed hole 15
Hole 14, is provided with the third through-hole 17 connecting with the first endoporus 13, third through-hole 17, the first endoporus 13 and in the core 4 that rises
In two endoporus 14 suit coolant delivery pipe 2, venthole 12 is provided with probe insert 3；Venthole 12 pass through the second endoporus 14,
Gap between third through-hole 17 and coolant delivery pipe 2 is connected with return gas channel 21；The first endoporus 13 and coolant delivery pipe 2 it
Between gap in be provided with scolding tin 1.
It is provided with hose connection 9 between cold head 10 left end and coolant return-air and silk guide passage pipe 8 right-hand member；In flexible pipe even
Auxiliary pilot hole is provided with female connector 9, seal wire 11 passes through auxiliary pilot hole.
The using method of the present embodiment, by means of said apparatus；Specifically include following steps:
Step a: seal wire 11 is inserted from by-pass prot 19 and from assisting pilot hole to expose, the end of seal wire 11 is exposed at cold head 10
Right side；
Step b: cold head 10 is inserted human body, the end guiding cold head 10 of seal wire 11 reaches diseased region；
Step c: seal wire 11 is taken out in by-pass prot 19；
Step d: carry out cryoablation operation.
For example, seal wire enters biliary tract through subcutaneous puncture passage, due to tumor and pathological tissues in biliary tract bending and biliary tract
Obstruction, need seal wire above exploring the way, cryoprobe enters biliary tract along seal wire, after cold head reaches diseased region, seal wire
Exit, cryoprobe starts cryoablation operation.
The cold head 10 of the present invention reaches diseased region under seal wire 11 guiding, in seal wire entrance guide pin bushing 7, coolant return-air and lead
On silk channel 8, hose connection 9, there is independent silk guide passage；Independent coolant return gas channel and independent silk guide passage are mutual
Not interference effect.
Using carbon freezing treatment technology, on the basis of setting up biliary drainage, application hose cryoprobe passes through
Percutaneous, directly carry out cryoablation and control through liver puncture drainage channel or through being directed to the obstructive focus of malignant tumor of biliary tract under scope
Treat, by destroying local tumor tissue, keep biliary tract unobstructed for a long time, improve liver function, and extend the survival of patients time limit.
Cold head 10 temperature should be maintained at -40 ° of c-- -60 ° of c, both guarantees to kill tumor cell, and activated cell immunity is anti-
Should, avoid too deep cryolesion to cause biliary tract fistula again.The diameter of cold head 10 should be it is ensured that can pass through between 1.8-2.4mm
Endoscope and percutaneous, through liver puncture pipeline work passage, and be soft connecting tube, arbitrarily bend.
Certainly, the application can also first stretch into cold head, then runs into tumor and pathological tissues in biliary tract bending and biliary tract
Hinder, then seal wire is stretched into guiding cold head and pass through to hinder.
Seal wire 11 guiding is convenient, and the corresponding cold head 10 of seal wire 11 stretches and arranges, it is to avoid impact freezing operation, independent leads
To main channel 24, it is to avoid influence each other with coolant path.The external world is exposed to by the left end from guiding main channel 24 for seal wire 11 left end,
I.e. using the axial passage manufacturing coolant return-air and silk guide passage pipe 8, reduce processing, main logical by guiding by-pass 25 and guiding
Road 24 forms three-port structure, plug-in mounting seal wire 11 convenience；The gap 16 that is fixedly clamped fastens a left side for coolant return-air and silk guide passage pipe 8
End, reasonable in design, it is connected firmly, good airproof performance；Positioning is realized by left positioning spigot 20, is connected by retainer ring 6, anyway respectively
Relatively rotate between part, thus avoiding damage to coolant return-air and silk guide passage pipe 8；Scolding tin 1 is realized connecting and sealing, certainly,
Can be clung using glue or other welding manners.
Auxiliary pilot hole realizes the righting to seal wire 11 it is ensured that seal wire 11 is parallel with cold head 10 axial line.
Compared with radiofrequency catheter thermal ablation techniques, the application have can repeatedly treat, patient is painless, low cost, operation
Simply, few intercurrent disease, therapeutic effect identical advantage.
Finally it is noted that above example, only in order to technical scheme to be described, is not intended to limit；Although
With reference to the foregoing embodiments the present invention is described in detail, it will be understood by those within the art that: it still may be used
To modify to the technical scheme described in previous embodiment, or equivalent is carried out to wherein some technical characteristics；Make
For those skilled in the art, multiple technical schemes of the present invention are combined being obvious.And these are changed or replace
Change, do not make the essence of appropriate technical solution depart from the spirit and scope of embodiment of the present invention technical scheme.
