The specific embodiment
Explain the spininess radio-frequency ablation electrode that is used for the treatment of tumor below in conjunction with Fig. 1 one Fig. 9.
As depicted in figs. 1 and 2, the spininess radio-frequency ablation electrode (hereinafter to be referred as ablating electrode) that is used for the treatment of tumor mainly comprises shank 5 and operating grip 7, shank 5 comprises the shank outer tube 15 of female pin 1 and hollow, taper shape or rhizoma sparganic taper are made in the tip of female pin 1, the hard when injected organism tissue so that puncture, in shank outer tube 15, be provided with female pin connecting rod 11, female pin 1 is connected with operating grip 7 by female pin connecting rod 11, between female pin connecting rod 11 and shank outer tube 15, be provided with sub-pin 2, (near-end is the end near handle at the near-end of female pin 1, far-end is the end near female pin) and the far-end of shank outer tube 15 between constitute sub-pin guide slit 4, the far-end of sub-pin 2 is provided with sub-pin expansion/retraction mechanism by sub-pin guide slit 4 expansion/withdrawals in operating grip 7, sub-pin deployment diameter adjusting device, device for detecting temperature and drug-injection in treatment device etc.
Shown in Fig. 1,2,7 and 9, sub-pin expansion/retraction mechanism comprises sub-pin expansion/withdrawal knob 8, gear 18, tooth bar 17 etc.Sub-pin expansion/withdrawal knob 8 is fixed by rib axle 23 (or by fixedly connected modes such as key connection, interference fit) and 18 cores of gear, gear 18 is meshed with tooth bar 17, the near-end of all sub-pins 2 all is fixed on the back side of tooth bar 17, near-end at tooth bar 17 is equipped with pointer 22, pointer 22 also is fixed on the back side (the no flank of tooth) of tooth bar 17, operating grip 7 is provided with sub-pin and launches rule 9, and pointer 22 tops are emissive plastic glazing 24.When rotating by sub-pin expansion/withdrawal knob 8 driven gears 18, tooth bar 17 just can vertically move, thereby driving all sub-pins 2 launches or regains, the operator can see through emissive plastic glazing 24 and see that pointer 22 indicated sub-pins on operating grip 7 launch the particular location of rule 9, thereby determines the length of sub-pin expansion/withdrawal.
Shown in Fig. 1-4, sub-pin deployment diameter adjusting device comprises the sub-pin guide slit adjusting knob 6 and one section hollow screw 16 of fixedlying connected with the near-end of shank outer tube 15 in the groove that is arranged on operating grip 7 far-ends.Sub-pin guide slit adjusting knob 6 is nuts that are complementary with hollow screw 16, since the indentation limitations of operating grip 7 far-ends the length travel of sub-pin guide slit adjusting knob 6, therefore it can only rotate in the far-end transverse section of operating grip 7, when gyrator pin guide slit adjusting knob 6, hollow screw 16 just vertically moves, thereby having driven shank outer tube 15 vertically moves, because the near-end of female pin connecting rod 11 is fixedlyed connected with the near-end of operating grip 7, this makes female pin 1 be positioned on the relatively-stationary position with operating grip 7, therefore rotate the gap length that sub-pin guide slit adjusting knob 6 can regulon pin guide slit 4, thereby the unfolded radius of curvature of regulon pin, sub-pin guide slit 4 is more little, and the unfolded radius of curvature of sub-pin is more little, and the unfolded diameter of sub-pin is just more little, the puncture intensity of sub-pin is high more, and vice versa.In addition, before ablation, available sub-pin guide slit adjusting knob 6 so that puncture, when treating that female pin 1 arrives the pathological tissues that needs treatment, is opened sub-pin guide slit 4 closures again with sub-pin guide slit 4, with sub-pin expansion/withdrawal knob 8 sub-pin 2 is launched then.
As shown in Figure 5, sub-needle guide also can adopt the structure of Fig. 5 to implement to slit 4.The near-end of shank outer tube 15 is fixed on the far-end of handle 7, and hollow screw 16 is fixed on the near-end of female pin connection tube 11, when gyrator pin guide slit button 6, as shown in Figure 5, because sub-pin guide slit adjusting knob 6 is subjected to the longitudinal spacing of handle 7, female pin connection tube 11 is moved up and down, thus the size of regulon pin guide slit 4.
As Fig. 2 and shown in Figure 8, device for detecting temperature comprises female needle thermocouple 14, sub-needle thermocouple 3, thermocouple line 20, RF line 21, leader cable 12 and plug 13 etc.Female needle thermocouple 14 is installed in the center of female pin 1, it can measure the maximum temperature of zone of ablation in real time, the temperature of this point can be controlled between 70 ℃-100 ℃, then the surface of female pin 1 and sub-pin 2 neither can produce incrustation and carbonization in ablation, can make the scope maximization of ablation again, therefore have the ablating electrode good effect of female needle thermocouple 14, safety might as well.Fig. 8 has also described the interior thermocouple line 20 of female pin 1, sub-pin 2, female pin connection tube 11 and pipe and the corresponding annexation of RF line 21.Every piece of sub-pin 2 all is made up of two thin metal pipes, and two strip metal tubules all are hollow, and wherein one links to each other with medicine-pouring hole, is used for to tissue injection medicinal liquid (will be described in detail below); Thermocouple line 20 or RF line 21 are housed in another strip metal tubule, and the far-end of sub-pin 2 is equipped with can thermometric sub-needle thermocouple 3, is used for monitoring the temperature that melts the border, and this can be used to assess therapeutic effect.Sub-needle thermocouple 3 in many pieces of sub-pins 2 is connected on the plug 13 through thermocouple line 20 and RF line 21 and by leader cable 12.Like this, the temperature data that female needle thermocouple 14 and sub-needle thermocouple 3 are monitored can be transferred on the relevant device, thereby reaches the monitoring to the diseased tissue area temperature.
As shown in Figure 6, the drug-injection in treatment device comprises medicine-pouring hole 10 and flexible pipe 19 etc.All sub-pins 2 all are to be made by metal thin tube, and the far-end of tubule is worn into sharp pointed, and its near-end links to each other with flexible pipe 19, and flexible pipe 19 communicates with medicine-pouring hole 10 again.By medicine-pouring hole 10 can be in pathological tissues medicinal liquids such as injecting normal saline, chemotherapy liquid medicine, lignocaine or ethanol, thereby reach the purpose of pathological tissues being carried out drug-injection in treatment.
