Present therapeutic electrode is cold circulation single needle structure, it thrusts the degree of depth is operated by rule of thumb by the doctor fully, its treatment area is little simultaneously, need repeated localised puncture to insert in patient's tumor for bigger tumor and just can reach therapeutic purposes, not only increase patient's misery, and prolonged operating time, increased medical workers, efficient can't improve, and is not suitable for the big tumor treatment of middle and advanced stage volume.
Summary of the invention
The objective of the invention is at the therapeutic electrode of single needle structure need repeated localised puncture when the big tumor of treatment and the efficient that exists low, increase patient's misery, the problem that prolongs operating time designs a kind of multi-electrode cool-tip electrode and solves this problem.
Technical scheme of the present invention is:
A kind of multi-needle cooled tip electrodes, comprise the electrode 1 that is provided with cavity, shell 2, pipe 6 in the pin is installed in the cavity of electrode 1, in shell 2, be equipped with by electrode canned paragraph 3, the interior pipe assembly 7 that pipe canned paragraph 4 and water inlet pipe canned paragraph 5 are formed in the pin, in electrode canned paragraph 3 and pin, be provided with backwater cavity 8 between the pipe canned paragraph 4, be provided with intake antrum 9 between pipe canned paragraph 4 and the water inlet pipe canned paragraph 5 in the pin, water inlet pipe 10 passes water inlet pipe canned paragraph 5 backs and communicates with intake antrum 9, return pipe 11 passes water inlet pipe canned paragraph 5 and the interior pipe of pin canned paragraph 4 communicates with backwater cavity 8, one end of electrode 1 is fixed in the electrode canned paragraph 3, its cavity communicates with backwater cavity 8, radio-frequency cable line 12 passes water inlet pipe canned paragraph 5, pipe canned paragraph 4 in the pin, electrode canned paragraph 3 backs link to each other with the current-carrying part of electrode 1, pipe 6 is fixed in the interior pipe of the pin canned paragraph 4 after passing electrode canned paragraph 3 in the pin, its tube chamber communicates with intake antrum 9, it is characterized in that on described electrode canned paragraph 3, being installed with at least three electrodes 1, correspondingly in pin, manage in the pin that also is fixed with equal number on the canned paragraph 4 and manage 6.
The quantity of described electrode 1 is three, and they are distributed on the electrode canned paragraph 3, and phase contrast is 120 degree.
Described electrode 1 stretches out to be set with on the end of shell 2 and makes the maintainance set 14 that the position remains unchanged between the respective electrode, on one between maintainance set 14 and the shell 2, several or whole electrode 1, be provided with can control electrode stretch into people's body length, the positioning element 13 of distance between control maintainance set 14 and the shell 2.
The present invention has the following advantages:
The present invention helps improving the treatment speed that swells and ache, and reduces puncture time, alleviates patient's misery, is applicable to the big tumor treatment use of volume.

The specific embodiment
The present invention is further illustrated for following structure drawings and Examples.
Shown in Fig. 1-8.
A kind of multi-needle cooled tip electrodes, comprise three electrodes 1 that are provided with cavity, shell 2, pipe 6 in the pin is installed in the cavity of every electrode 1, as shown in Figure 1, in shell 2, be equipped with by electrode canned paragraph 3, the interior pipe assembly 7 that pipe canned paragraph 4 and water inlet pipe canned paragraph 5 are formed in the pin, in electrode canned paragraph 3 and pin, be provided with backwater cavity 8 between the pipe canned paragraph 4, be provided with intake antrum 9 between pipe canned paragraph 4 and the water inlet pipe canned paragraph 5 in the pin, water inlet pipe 10 passes water inlet pipe canned paragraph 5 backs and communicates with intake antrum 9, return pipe 11 passes water inlet pipe canned paragraph 5 and the interior pipe of pin canned paragraph 4 communicates with backwater cavity 8, as shown in Figure 2; One end of electrode 1 is fixed on electrode canned paragraph 3 (as Fig. 3, shown in 4, through hole among the figure is the jack of fixed electrode, available glue is fixed after electrode inserts this through hole, and this through hole carried out shutoff) in, its cavity communicates with backwater cavity 8, radio-frequency cable line 12 passes water inlet pipe canned paragraph 5, pipe canned paragraph 4 in the pin, electrode canned paragraph 3 backs link to each other with the current-carrying part of electrode 1, pipe 6 is fixed on the interior pipe of pin canned paragraph 4 (as Fig. 5 after passing electrode canned paragraph 3 in the pin, shown in 6, Fig. 5, the through hole in 6 are pipe fixing hole in the pin, fix with the glue shutoff after pipe in the pin 9 inserts these through holes) in, its tube chamber communicates with intake antrum 9, three electrodes 1 are fixed on the electrode canned paragraph 3 in the mode that differs 120 degree angles, and 6 one ends of pipe insert in the electrode 1 in three pins, and the other end is fixed on the interior pipe of the pin canned paragraph 4.Because the length of electrode 1 is longer, in order to prevent that electrode 1 from inserting occurrence positions variation in the human body process, therefore the present invention has designed a maintainance set 14, as Fig. 7, shown in 8, each electrode 1 all is actively plugged in this maintainance set 14, maintainance set 14 can move on electrode, thrust between maintainance set 14 and shell 2 one of the degree of depth in the body tumor tissue for the ease of control electrode 1, several or whole electrodes 1 are provided with and can control electrode stretch into people's body length, the positioning element 13 of distance between control maintainance set 14 and the shell 2, positioning element 13 can adopt fixation clamp or similar structure, be clamped in use on the electrode, can take off easily when not needing to use.
The surface of electrode 1 of the present invention also should add the same with prior art, covered insulating coating, and each parts material therefor all should meet relevant medical standard, and it is all same as the prior art not relate to part.
