The utility model compared with prior art, has the following advantages that：The utility model is simple in construction, compact, reasonable, behaviour
Facilitate, hidden water pocket bag can be made to fill glomeration by water filling, with the intestines and stomach for obstructing liver with being close to liver, prevented micro-
Heat caused by ripple ablation needle is burnt the intestines and stomach closed on, improves the liver tumour security that intestines and stomach are close in ablation, actual use
Effect is good, safe.
Brief description of the drawings
Fig. 1 is the operational circumstances schematic diagram for clinically implementing microwave ablation operation at present.
Fig. 2 is the structural representation of the utility model embodiment.
Fig. 3 is the A portions enlarged diagram in Fig. 2.
Fig. 4 is the concrete operations situation schematic diagram of the utility model embodiment.
Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As shown in the figure：Microwave ablation in embodiment isolates pin mainly by puncture needle body 4, guiding needle body 5, water filling with water filling
Pipeline 6, water filling joint 7, closure 8 and hidden water pocket bag 9 etc. form.
As shown in Figure 2 to 4, the puncture needle body 4 is hollow-core construction, is set puncturing the inside of needle body 4 close to front position
There is hidden water pocket bag 9, be provided with filling pipe 6 puncturing in needle body 4, the front end of filling pipe 6 connects with the hidden water pocket bag 9
Logical, the rear end of filling pipe 6 is connected with water filling joint 7.
In use, the position that pin puncture liver 2 reaches needs and isolate first is isolated into water filling, the connection syringe of water filling joint 7,
Hidden water pocket bag 9 is filled glomeration by syringe water filling, with the intestines and stomach 3 for obstructing liver 2 with being close to liver 2, prevent micro-
Heat caused by ripple ablation needle 1 is burnt the intestines and stomach 3 closed on, improves the liver tumour security that intestines and stomach 3 are close in ablation.
It is typically relatively more sharp due to puncturing the front end of needle body 4, after the hidden water-filling of water pocket bag 9 expansion, it might have and be punctured pin
The risk that the tip of body 4 punctures, does not have buffer action, and optimization design as shown in Figure 2 to 4 is employed for this present embodiment,
Filling pipe 6 and hidden water pocket bag 9 are designed to be able to the form moved axially inside puncture needle body 4.So, puncturing
After in place【Hidden water pocket bag 9 reaches the position for needing to isolate】, needle body 4 will be punctured and dropped back certain distance, while keep water filling
Pipeline 6 is motionless, is left in place hidden water pocket bag 9, then hidden water pocket bag 9 is filled glomeration by syringe water filling, so
Avoid the risk being punctured after the hidden water-filling of water pocket bag 9 expansion.After the completion of operation, first by the water in hidden water pocket bag 9
Extract out, it is mobile further along to puncture needle body 4, hidden water pocket bag 9 is re-incorporated INTO wherein, then extracted together.
Dropped back in view of puncture needle body 4 and there may be the problem of puncture misplaces further along, the present embodiment has been carried out further
Optimization.As shown in Figure 2 to 4, it is described puncture needle body 4 in be provided with guiding needle body 5, it is described guiding the outside dimension of needle body 5 with
Puncture the internal diameter size of needle body 4 to match, puncturing needle body 4 can move axially along guiding needle body 5, the filling pipe 6 and hidden
Cover water pocket bag 9 to be arranged in guiding needle body 5, the guiding front end edge mouth of needle body 5 uses round and smooth design.So, guiding needle body 5 still stays
At the position that needs are isolated, and because the guiding front end edge mouth of needle body 5 is round and smooth design, also will not after hidden water pocket bag 9 is full
It is punctured, mobile further along after the completion of operation to puncture needle body 4, guiding needle body 5 can play guide effect, it is wrong to avoid the occurrence of puncture
Position problem, substantially increases operation accuracy.
As shown in Fig. 2 in the present embodiment, for the ease of the displacement of control water filling isolation each part of pin, the water filling
Pipeline 6 is provided with scale.The starting point of the scale is located at the intersection of water filling joint 7 and filling pipe 6.
As shown in Fig. 2 in the present embodiment, the water filling joint 7 is furnished with closure 8, can connect water filling after water has been noted
First 7 seal up, and prevent water adverse current.Use and be threadedly coupled between the closure 8 and water filling joint 7.
In the present embodiment, the filling pipe 6 uses medical rubber hose or medical PVC pipe.The hidden water pocket bag 9 uses
Medical grade rubber material is made.
