Description
Technical field
The utility model belongs to technical field of medical equipment more particularly to a kind of water circulation ablation barrier sacculus.
Background technique
Currently, Incidence is in more and more trend, it is later when because of most tumors discovery, and some patientss
Because overall health of patients is poor, cannot bear or be reluctant to perform the operation, the heating ablations such as microwave ablation, RF ablation because its wound is small, good effect, this
When can play preferable therapeutic effect, the discovery of research both at home and abroad is to small liver cancer, 5 years survival rates of diagnosis of small renal cell carcinoma and operation without obvious poor
It is different, to make RF ablation and microwave ablation in liver cancer, kidney, cancer of pancreas, diagnosis of hepatic metastases, metastatic adrenal tumors, Intraperitoneal lymph
It is had been more and more widely used in the treatments of malignant tumours such as knot metastatic tumor, but is proximate to gall-bladder, stomach, jejunum, colon, the heart
The danger zones such as packet, diaphram, mediastinum, lethal, the great complication such as disable is caused because worrying these organs of thermal damage and cannot
Ablation completely, and cannot be melted completely close to angiosomes because worrying thermal damage's blood vessel or hot subsidence effect, to reduce
The life cycle of therapeutic effect and patient.
In conclusion problem of the existing technology is:
Existing partial ablation equipment have been combined SAPMAC method ablation carry out needle track protection, pain when ablation is effectively reduced, but
It is poor to the protection of risk organs；Document has been reported that because the heating ablations such as RF ablation, microwave ablation lead to gall-bladder, stomach, jejunum, knot
The organ perforations such as intestines, infection, lethal case, to some water injection technology protection internal organs, external some scholar's applications occur
Sacculus fills the water Barrier Technology and carries out heating ablation protection, has sacculus to deform, rupture, be not easily taken out of because of ablation in thermal ablation process
Situation occurs, and because water filling sacculus water injection rate is limited, the larger ablation time of tumour is longer, and sacculus cannot block all heats, can
With cause gall-bladder, stomach, jejunum, colon, diaphram, pericardium these risk organs thermal damage.
Utility model content
In view of the problems of the existing technology, the utility model provides a kind of water circulation ablation barrier sacculus.
The utility model is realized in this way a kind of water circulation ablation barrier sacculus, the water circulation ablation barrier sacculus
It is provided with inlet and outlet pipes；The inlet and outlet pipes are connected to sacculus；The sacculus is located at water inlet pipe
The front end in road and outlet conduit；The inlet and outlet pipes are isolated by isolation board.
Further, the outlet conduit is communicated with triple valve by hose；Fluid stopping spool is inlaid on the triple valve.
Further, pressoreceptor is inlaid on the hose.
Further, the water inlet line is communicated with water structure by hose；The front end of the isolation board and water inlet line,
The front end of outlet conduit is mutually neat.
The advantages of the utility model and good effect are as follows:
Water circulation ablation barrier sacculus solves the problems, such as water flowing in sacculus, and water temperature in sacculus is made to be in low always
Temperature solves the problems, such as sacculus because of thermal deformation, rupture, discharges water in sacculus after ablation, extract ball out by puncture path
Capsule plays a protective role, and pass through water when SAPMAC method ablation barrier sacculus can melt between lesion and risk organs
Circulation can more play the role of protecting risk organs, and water circulation can also be a kind of protection to sacculus itself, avoid sacculus because of heat
It damages and deformation, rupture, sacculus is caused to be not easily taken out.It is can effectively protect sacculus itself in this way, also preferably avoids heat
Damage of the heat to dangerous internal organs around, improves complete ablation factor, expands the idicatio of heating ablation, to extend when ablation
Life cycle of patient.

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
Existing ablation apparatus is not bound with SAPMAC method ablation and carries out protection risk organs；And existing ablation apparatus is variable
Shape, rupture, sacculus are not easily taken out.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
As shown in Figure 1, water circulation ablation barrier sacculus provided by the embodiment of the utility model, is provided with 2 He of water inlet line
Outlet conduit 3；The inlet and outlet pipes are connected to sacculus 4；The sacculus is located at inlet and outlet pipes
Front end；The inlet and outlet pipes are isolated by isolation board.
The outlet conduit 3 is communicated with triple valve 5 by hose；Fluid stopping spool is inlaid on the triple valve.
Pressoreceptor 6 is inlaid on the hose.
The water inlet line is communicated with water structure 7 by hose；The front end of the isolation board and water inlet line, outlet pipe
The front end in road is mutually neat.
As shown in Figures 2 to 4, the utility model is accommodated in the inner in core sleeve 1 by inner core casing 1 and needle core 8, needle core 8,
Needle core 8 is pierced into patient affected part.It extracts needle core out, retains inner core casing 1.Water circulation ablation barrier sacculus is allowed to arrive by inner core casing 1
Up to affected part.Start to fill the water, balloon inflation plays barrier action, according to circumstances opens water outlet and carries out cooling water circulation.
The sacculus implantation of the utility model is after being punctured between lesion and dangerous internal organs by blunt nosed puncture needle, to extract it
Sacculus is discharged into position by needle core, water filling, water filling to it is a certain amount of can play separate barrier action after, needle core can be punctured into swollen
Tumor lesion opens inlet and outlet in ablation, carries out water circulation.
The utility model is punctured using needle core, inner core casing 1 be it is blunt nosed, needle core is taper needle, point different model (12-
16G), needle core is exited, sacculus is replaced, water filling utilizes balloon expandable passage circumferential cavity internal organs or reality internal organs, sacculus point difference
Model (diameter 3CM, 5CM, 7CM etc.), balloon diameter is larger as far as possible, and balloon wall selects the higher material of compliance.
Water flow can have injection channel in sacculus, also there is efferent tract, and compliance is high, and heat-resisting 200 degree, 1--2 hours.Efferent tract
Threeway can be connect, outflow can be suspended when injecting water, water is needed to flow out again when recycling.It flows into as the rate of outflow.There is one
Divide hose, there is pressoreceptor.
Work as injection water, and when the ablation barrier sacculus of flowing water can block ablation heat to gall-bladder, stomach, jejunum,
The thermal damage in the regions such as pericardium, diaphram.And sacculus can be withdrawn from after melting, it restores to the original state.
Pressoreceptor concrete model YZII15 pressoreceptor.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
