Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.It needs to illustrate herein
It is the explanation of these embodiments to be used to help to understand the present invention, but do not constitute a limitation of the invention.In addition, below
Involved technical characteristic as long as they do not conflict with each other can phase in the described each embodiment of the present invention
Mutually combination.
Referring to Figure 1 to 3, a kind of microwave tumour needle construction is shown in the figure, is designed and manufactured for laparoscopic surgery
, meet the operation principle of laparoscope.
The microwave tumour needle construction is mainly by groups such as elongated needle tubing 1, aspiration means 2, water flow component 3 and microwave components 4
At.
The elongated needle tubing 1 has needle tubing front 11 and needle tubing rear portion 12.
The needle tubing front 11 is radiation cover portion.The connection needle tubing front is formed on the front end of the needle tubing front 11
Suction orifice 110 inside 11.In order to smoothly be inserted into cyst, the front end of the needle tubing front 11 is designed to taper.
The internal layer that 12 accommodated inside of needle tubing rear portion has outer layer pipeline 121 and is placed in inside the outer layer pipeline 121
Pipeline 122.The front end and rear end of the internal layer pipeline 122 are open end.The front end of the outer layer pipeline 121 is closed end.
The rear end of the outer layer pipeline 121 is open end.Whereby, first passage 1201 is formed inside the internal layer pipeline 122.In described
Second channel 1202 is formed between layer pipeline 122 and the outer layer pipeline 121.The outer layer pipeline 121 and the needle tubing rear portion 12
Form third channel 1203.The front end of the first passage 1201 is connected with the front end of the second channel 1202.Described
It is connected inside the front end of triple channel 1203 and the needle tubing front 11.
There is the aspiration means 2 cyst fluid suction pipeline 21, control switch 22 and negative pressure to provide source (not shown).It is described
Wherein one end of cyst fluid suction pipeline 21 is connected with the rear end of the third channel 1203.The control switch 22 is placed in institute
It states between the other end of cyst fluid suction pipeline 21 and negative pressure offer source.The control switch 22 is for selectively communicating with or hindering
The cyst fluid suction pipeline 21 of breaking provides source with the negative pressure.When the control switch 22 be connected to the cyst fluid suction pipeline 21 with
The negative pressure provides source, inside the third channel 1203 being connected to the cyst fluid suction pipeline 21, the needle tubing front 11
It is in negative pressure state.If the front end of the needle tubing front 11 has been inserted in tumour, by suction function, cyst fluid in tumour from
The suction orifice 110 enters the needle tubing front 11, by the third channel 1203, into the cyst fluid suction pipeline
21, finally it is extracted.
The water flow component 3 has inlet pipeline 31 and outlet pipeline 32.Wherein one end of the inlet pipeline 31 is used for
Water inlet.The other end of the inlet pipeline 31 is connected with the rear end of the first passage 1201.The outlet pipeline 32 its
Middle one end is for being discharged.The other end of the outlet pipeline 32 is connected with the rear end of the second channel 1202.Whereby, cooling
Water enters from the inlet pipeline 31, successively pass through the first passage 1201, the second channel 1202, finally from it is described go out
Water lines 32 flow out.Cooling water cools down the microwave coaxial cable 42, prevents the microwave coaxial during flowing through
Cable 42 burns out and scalds sufferer.
The microwave components 4, which have, to be placed in the Microwave emission terminal 41 inside the needle tubing front 11 and is placed in described
Microwave coaxial cable 42 inside internal layer pipeline 122.The front end of the microwave coaxial cable 42 is before the internal layer pipeline 122
End is pierced by and extends to 11 inside of needle tubing front and the Microwave emission terminal across the front end of the outer layer pipeline 121
41 are connected.The microwave coaxial cable 42 is used to convey microwave to the Microwave emission terminal 41.When the Microwave emission end
Son 41 works, and the microwave generated by the Microwave emission terminal 41 is micro- to realize by projecting outside 11 directive of needle tubing front
Wave ablation.
Use process: step 1, the needle tubing front 11 is inserted in tumour；Step 2, the control switch 22 is opened,
Cyst fluid is extracted out from tumour using aspiration means 2；Step 3, the Microwave emission terminal 41 is enabled, it is micro- using microwave components 4
Wave melts cyst wall, inactivation the inside cancer cell tissue that may be present.In ablation procedure, while it is cooling to enable the water flow component 3
The microwave coaxial cable 42.
It is not difficult to find that microwave tumour needle construction provided in this embodiment can inject in tumour before ablation and cyst fluid is sucked out
It makes a return journey the property for doing cytology pathology to determine tumour, there is revolutionary breakthrough.Also, exhausting cyst fluid, not need needle exchange direct
Microwave ablation can be carried out for the capsule leather bag liquid of tumour using this, thoroughly heating makes its really necrosis.
Embodiments of the present invention are only expressed above, and the description thereof is more specific and detailed, but and cannot therefore understand
For the limitation to patent of invention range.It should be pointed out that for those of ordinary skill in the art, not departing from this hair
Under the premise of bright design, various modifications and improvements can be made, and these are all within the scope of protection of the present invention.Therefore, this hair
The scope of protection shall be subject to the appended claims for bright patent.
