Described thermometric electrode and two heating electrodes are along the not strict restriction of the order of arranging on the body length direction, as preferably, described thermometric electrode is between two heating electrodes, can suitably strengthen two distances between the heating electrode like this, heating surface (area) (HS is bigger during work, the temperature signal that the thermometric electrode is gathered is convenient to the accurate control of heating electrode running voltage and lesions position temperature also more near practical situation, uses more safe and reliable.
Fill up chamber head, fluid injection chamber head and exhaust chamber head and be tubular structure, fill up sacculus on the head of chamber and fill up check valve and only when injected media in sacculus, open, avoid sacculus to fill up after voluntarily the fluid injection check valve on the head of fluid injection chamber only when carrying out fluid injection, open.
The position that the length of body of the present invention, outage, liquid injection hole and sacculus fill up the hole all can be as required and the difference of subject adjust.Guidewire lumen, sacculus fill up the also not strict restriction of cross sectional shape in chamber, exhaust chamber and fluid injection chamber.
As preferably, described thermometric electrode and two heating electrodes are loop configuration, excircle around body is arranged, location for the ease of thermometric electrode and two heating electrodes, excircle around body is distributed with some annular protrusions, the both sides of thermometric electrode and two heating electrodes all have described annular protrusion, and annular protrusion also can further play buffer action and avoid thermometric electrode and two heating electrodes and patient's tract skin covering of the surface sticking.
In sum, beneficial effect of the present invention is:
1. adopt exposed heating electrode, increased the heating surface area of lesions position, be beneficial to heating to treat of whole lesions position.
2. adopt exposed thermometric coil, measured temperature is consistent with temperature in patient's tract, helps lesions position treatment temperature and reaches optimum state, has improved therapeutic effect.
3. medicine (or normal saline) is flow regime after injecting, and can have been improved therapeutic effect by the abundant saturated utilization of lesions position.
Description of drawings
Fig. 1 is the structural representation of heat treatment catheter of the present invention;
Fig. 2 is an A-A cutaway view among Fig. 1.
The specific embodiment
Referring to accompanying drawing, heat treatment catheter of the present invention comprises body 10, body 10 inside along its length direction be provided with mutual isolated guidewire lumen 11, sacculus fills up chamber 12, exhaust chamber 14 and fluid injection chamber 13;
The surface of body 10 has the outage 141 that communicates with exhaust chamber 14, the liquid injection hole 131 that communicates with fluid injection chamber 13 from the head successively and fills up the sacculus that chamber 12 communicates with sacculus and fills up hole 121 to the middle part;
Sacculus fills up 121 peripheries, hole and is covered with sacculus 30, and wherein sacculus fills up chamber 12 1 ends and fills up hole 121 with sacculus and communicate, and the other end is drawn body 10 by the piped chamber 42 that fills up, and fills up chamber 42 and is provided with sacculus and fills up check valve 52.When sacculus fills up the normal saline that check valve 52 charges into, sacculus 30 can be filled up glomeration.Sacculus fills up check valve 52-sacculus and fills up chamber 12-sacculus and fill up hole 121-sacculus 30 and be an independently cavity lane, and is not connected with other cavitys.
Outage 141 and the outer wall between the liquid injection hole 131 at body 10 are provided with thermometric electrode 23, heating electrode 21 and heating electrode 22, thermometric electrode 23 is between heating electrode 21 and heating electrode 22, lead 24 in thermometric electrode 23, heating electrode 21 and heating electrode 22 and the guidewire lumen 11 is connected, and the other end of lead 24 is drawn and access control system (therapeutic instrument main frame) from the afterbody of body 10.
Heating electrode 21 and heating electrode 22, thermometric electrode 23 adopts stainless steel, and behind normal saline or medicinal liquid submergence that electrode is injected into, therapeutic instrument can discharge radio-frequency (RF) energy between electrode, produces heat effect and non-thermal effect.Thermometric electrode 23 is the temperature high-precision sensor, can detect the actual temperature of therapentic part accurately.
Thermometric electrode 23, heating electrode 21 and heating electrode 22 are loop configuration, excircle around body 10 is arranged, thermometric electrode 23, heating electrode 21 and heating electrode 22 reach both sides each other and are distributed with annular protrusion, annular protrusion and body 10 outer walls are structure as a whole, and visible heating electrode 21, thermometric electrode 23 and heating electrode 22 intervals is arranged between annular protrusion 1, annular protrusion 2, annular protrusion 3 and the annular protrusion 4 among the figure.Also can further play buffer action avoids thermometric electrode and two heating electrodes and patient's tract skin covering of the surface sticking.
Top guide 15 is blocked the head of the tract in the body 10, and makes catheter head smooth, is convenient to just live
When heat treatment catheter of the present invention uses (for example conduit being inserted patient's intravaginal),, fill up check valve 52, inject normal saline, sacculus 30 is filled up with syringe by sacculus when sacculus 30 rear portions enter the about 5-10mm of vaginal orifice place.Sacculus 30 after filling up had both played the effect of A/C, also played the effect of sealing vagina.
Pass through gravity drip, normal saline (or medicinal liquid) is from fluid injection check valve 53, by fluid injection chamber 13, liquid injection hole 131 normal saline or medicine are injected patient's lesions position, when the liquid that instils covered the outage 141 that is positioned at catheter head, liquid just flowed out from exhaust chamber head 44 through exhaust chamber 14 from outage 141.
Therefore normal saline (medicinal liquid) forms a mobile loop from fluid injection check valve 53-fluid injection chamber 13-liquid injection hole 131-lesions position-outage 141-exhaust chamber 14-exhaust chamber head 44.This loop on the one hand provides medium for the energy of electrode discharges in therapeutic process, on the other hand can the adjustment of treatment temperature, the metabolite in the therapeutic process is in time excreted.The sticking problem that is difficult for peeling off of film has been avoided on continued to flow simultaneously thermometric, heating electrode and human intracavity surface.
