Further, the outer end of described needle tubing is provided with the vacuum seal wing, it is adhesively fixed with buffer ferrule, the connection end of needle tubing Yu buffer ferrule is carried out once sealing, the outside of the vacuum seal wing is provided with the fixing envelope wing, the vacuum seal wing is wrapped circumferentially around by the fixing envelope wing, and the connection end of needle tubing Yu buffer ferrule is risen secondary seal；The side seal wing, bonds with colloid respectively with the connection end of the vacuum seal wing and the fixing envelope wing, is wrapped circumferentially around in buffer ferrule and the outside of preposition cavity.
Further, described needle tubing runs through and stretches out inside the vacuum seal wing, and the fixing envelope wing seals a section that the vacuum seal wing is connected with buffer ferrule, and one end that the vacuum seal wing exposes is in sharp mouth shape.
Further, described electrode is at least provided with one.
The main advantage of the technical program is presented as:
1, secondary seal, good airproof performance are used.
2, electrode connects electrode fixing device and can be external to computer, can judge that affected area clicks on extended position and extension size accurately by connecting computer.
3, provide handle, be beneficial to operation during operation.
4, extend the quantity of electrode, number of electrodes can be set according to conditions of patients, reach the effect of seance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
As shown in Figure 1, a kind of radio frequency ablation needle treating malignant tumor, including T-handle 1, connecting the axle 2 of T-handle 1, described axle 2 is provided with turncap 6 and needle tubing body, turncap 6 is connected with needle tubing body by needle tubing connector 7, needle tubing body, described needle tubing body is provided with buffer ferrule 10, and the rear end of buffer ferrule 10 connects needle tubing 13, the front end of buffer ferrule 10 has the preposition cavity 8 being wholely set with buffer ferrule 10, the front end of preposition cavity 8 to be demountable needle tubing connectors 7.
Being provided with electrode fixing device 3 on axle 2, be provided with electrode 12 in it, electrode 12 extends to outer end along axle 2 through needle tubing body and needle tubing 13, the sensor 5 being arranged on axle 2, and the lower end of sensor 5 is provided with stretching knob 4, and electrode 12 is fixed on stretching knob 4.
Further, the outer end of described needle tubing 13 is provided with the vacuum seal wing 14, the vacuum seal wing 14 is adhesively fixed with buffer ferrule 10, the connection end of needle tubing 13 with buffer ferrule 10 is carried out once sealing, the outside of the vacuum seal wing 14 is provided with the fixing envelope wing 11, the vacuum seal wing 14 is wrapped circumferentially around by the fixing envelope wing 11, and the connection end of needle tubing 13 with buffer ferrule 10 is risen secondary seal；The side seal wing 9, bonds with colloid respectively with the connection end of the vacuum seal wing 14 and the fixing envelope wing 11, is wrapped circumferentially around in buffer ferrule 10 and the outside of preposition cavity 8.
