Description
Technical field
The present invention relates to a kind of microwave coagulation antenna, more particularly to a kind of plug-in type crosspointer microwave for hepatectomy
Coagulation system.
Background technology
Liver is the vitals of human metabolism, is used to receive with Quadruplet pipe road system and exports blood, therefore,
Liver is a multivessel organ, causes, when carrying out operation on liver, easily occur bleeding, hepatectomy is high one of difficulty
Plant operation.
Classical hepatectomy need to be blocked frequently cuts liver into hepatic blood flow, then row clamp method.Currently used for auxiliary hepatectomy
Principle of instrument is related to ultrasonic energy, high-frequency energy, radio frequency etc., wherein, ultrasonic suction knife（CUSA）With the combination quilt of bipolar coagulation
It is considered most perfectly to combine：While CUSA smashes liver organization, the blutpunkte on bipolar coagulation solidification liver section is completed
Hepatectomy.In the case of having advanced instrument auxiliary, average each hepatectomy amount of bleeding can also reach 600~1000ml.
The hepatotomy for merging hepatic sclerosis in addition is still a problem for surgeon.On the one hand, ultrasonic suction knife（CUSA）It is uncomfortable
Liver with cirrhosis is answered, on the other hand, frequently stops that example enters hepatic blood flow, can cause major Liver ischemical reperfusion injury, can increase
The occurrence probability of the liver function decay of liver with cirrhosis.Meanwhile, when carrying out malignant tumor of liver excision, ultrasound knife, CUSA and electricity
Knife is difficult to borderline tumor excision totally, easily cause residual tumor, postoperative easily tumor recurrence occur.
To solve the above problems, can research and develop using radio frequency and microwave energy to aid in hepatectomy.
The content of the invention
It is an object of the invention to provide a kind of plug-in type crosspointer microwave coagulation device for hepatectomy, solve existing
With the presence of the shortcoming of technology.
The present invention adopts the following technical scheme that realization：
A kind of plug-in type crosspointer microwave coagulation device for hepatectomy, it is characterised in that including a handle, the hand
It is provided with ablation needle, waterpipe jointing and microwave cable interface, the ablation needle and is provided with before coaxial cable, ablation needle on handle
End is provided with microwave radiation device, and the coaxial cable includes inner wire and outer conductor, insulation is provided between inner and outer conductor
Body, is provided with microwave antenna in the microwave radiation device, and the microwave antenna is connected with inner wire.
Further, the ablation needle is two, and a diameter of 2mm of ablation needle, length is between 100mm, ablation needle
Distance is 15mm.
Further, the auxiliary fixed block for fixing ablation needle is provided between two ablation needles.
The method have the benefit that：1st, when operative region is larger, using microwave coagulation antenna repeatedly in pre-cut
Except carrying out solidifying-lock out operation on face, with regard to surgery excision can be completed.Because excision is carried out in tissue coagulation area, for swollen
For knurl excision, particularly pre-cut face is pressed close to for the excision of tumour, and this operation improves operation for reducing residual tumor
Radical rate is beneficial；2nd, the tissue of target area and below 2mm blood vessel can be solidified, it is to avoid the expansion of solidification zone, had
Beneficial to the generation for reducing the related complication of postoperative ablation.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
By the following description to embodiment, it will more contribute to the public understanding present invention, but can't should be by Shen
Given specific embodiment of asking someone is considered as the limitation to technical solution of the present invention, any definition to part or technical characteristic
Be changed and/or make form to overall structure and immaterial conversion is regarded as what technical scheme was limited
Protection domain.

The cooling chamber in microwave power distributor and inner water-tank, connection handle 3 and ablation needle is included in water pipe, handle 3, circulating chilled water is used
Handle and ablation needle are cooled down.Each ablation needle is made up of the microwave radiation device of coaxial cable and front end, coaxial electrical
Cable includes inner wire and outer conductor, and insulator is provided between inner wire and outer conductor, and microwave radiation device is provided with microwave day
Line, microwave antenna is connected with inner wire, provided with an auxiliary fixed block between two ablation needles, plays fixed ablation needle,
Ablation needle diameter 2mm in the present embodiment, long 100mm, between at a distance of 15mm.The specific reality of ablation needle 1, the present embodiment of ablation needle 2
Now method is：The coaxial cable of ablation needle 1 and ablation needle 2 is connected with the interface of the two-way power splitter inside handle 3, simultaneously
Cooling system inside ablation needle is connected with the water tank of handle inner, microwave cable interface 4 and the two-way work(inside handle 3
Divide the input interface of device to be connected, realize the function of microwave input；Waterpipe jointing 5 and the water tank input interface phase inside handle 3
Connection, realizes the function by shank cooling is melted.
Certainly, the present invention can also have other various embodiments, in the case of without departing substantially from spirit of the invention and its essence,
Those skilled in the art can make various corresponding changes and deformation according to the present invention, but these it is corresponding change and
