The utility model content
The purpose of this utility model is to provide a kind of esophagus pace mapping and temperature monitoring electrode catheter (being called for short ET) that can have accurate mapping and multiple spot function of temperature control concurrently.
This utility model esophagus pace mapping and temperature monitoring electrode catheter, comprise a sleeve pipe, one operating grip that is connected with the sleeve pipe tail end and the electrode that is positioned at the sleeve pipe head end, described electrode is to be divided into a plurality of electrodes of two groups, one group is temperature electrode, another group is the mapping electrode, and all electrodes vertically are laid in telescopic head end along sleeve pipe, and temperature electrode and the arrangement of mapping electrode gap.
Described esophagus pace mapping and temperature monitoring electrode catheter are established five temperature electrodes and six mapping electrodes.
Wherein, each electrode all is connected with conductive leads, and lead is located in the sleeve pipe, and stretches out outside the sleeve pipe by an opening of being located at the sleeve pipe rear end and to be connected with polygraph.
The lead of a plurality of mapping electrodes is connected with polygraph respectively with a plurality of interfaces, and the lead of a plurality of temperature electrodes is combined into one and is connected with polygraph with an interface.
Adjacent electrode spacing 10mm in the described electrode array.
Sleeve pipe is made with flexible material, and is flexible at the sleeve pipe front end.
Adopt above technical scheme, this utility model concentrates on multiple electrode on the esophagus electrode.This product can not only be pressed close to the esophagus antetheca by control electrode, and a plurality of perception chips are arranged.The mapping function is arranged simultaneously, also have pacing function.Thereby increased a new electrode during for clinical intracardiac radio-frequency (RF) ablation, can increase clinical mapping function greatly, made radio-frequency (RF) ablation operate easily.In fact this product is equivalent to the combination of a big tip electrode and esophagus temperature control electrode.
Description of drawings
Fig. 1 is the structural representation of this utility model electrode catheter.
The specific embodiment
This utility model is a kind of new-type esophagus pace mapping and temperature monitoring electrode catheter (being called for short ET). similar with esophagus temperature control electrode in the prior art, this utility model electrode catheter mainly is made up of front end electrode array 1 three parts of sleeve pipe 2, the operating grip 3 that links to each other with sleeve pipe 2 and sleeve pipe 2, referring to shown in Figure 1.
Wherein: head end electrode array 1 comprises one group of temperature electrode 11 and one group of mapping electrode 12, and all electrodes vertically are laid in the head end of sleeve pipe 2 along sleeve pipe 2, and temperature electrode 11 and mapping electrode 12 are spaced.As five temperature electrodes 11 and six situations that mapping electrode 12 is vertically arranged at interval, adjacent electrode spacing 10mm have been shown among Fig. 1.Identical with existing esophagus temperature control electrode, each electrode all is connected with conductive leads, lead is located in the sleeve pipe 2, and stretch out outside the sleeve pipe 2 by an opening 21 of being located at sleeve pipe 2 rear ends and to be connected with polygraph, the current potential that electrode is recorded spreads out of by conductive leads, writes down potential change on the instrument leading more.In this utility model, the lead 13 of six mapping electrodes 12 is connected with polygraph respectively with six interfaces, reach the mapping purpose so that distinguish the electrode numerical value of different parts, and the lead 14 of five temperature electrodes 11 can be combined into one and is connected with polygraph with an interface, with the multiple-point integrated temperature that obtains to measure by a plurality of temperature electrodes 11.
Sleeve pipe 2 can use plastics, terylene woven material or novel extruding synthetic material such as polyurethane etc. to make, and is provided with opening 21 in sleeve pipe 2 rear ends.
Operating grip 3 is located at ET electrode catheter tail end, which is provided with control knob 31, button 31 is connected with the piston of being located at inside, by push-and-pull button control piston, the head end of piston interlock conduit 2 can be regulated conduit 2 head end cambers, head end bending during preceding pushing away, head end stretches (operating grip control section design is prior art with to have left lung vein electrode catheter LASSO now identical) during post-tensioning; In this utility model, the design button makes presses close to esophagus antetheca (is crooked because of the esophagus antetheca in the atrium aft section) when conduit 2 head ends are crooked.
When this utility model uses, carry out following operation: after earlier this electrode head end being lubricated with paraffin oil, enter esophagus through patient's nasal cavity.Under X-ray contrast machine perspective, the electrode head end is entered the same level in position, ablation catheter place fully.Make head end be in complete appropriateness by adjusting handle in the esophagus position.The electrode tail end is connected with electric physiology polygraph, records current potential.
Can recognize by above description, the utlity model has following characteristics:
1, ablation site is up and down when ablative surgery, so the temperature at a position of single monitoring, is difficult to represent the temperature of ablation site, such as the accurate position monitor temperature of need, need to move up and down conduit, increases patient's misery. Adopt the utility model once to use an electrode catheter namely can monitor the temperature of different parts, needn't mobile conduit just can the perception accurate location temperature, reduce the patient suffering. The utility model can be monitored the temperature of esophagus antetheca simultaneously.
2. can adjust the catheter end head position by handle during location of operation, so that electrode is pressed close to the esophagus antetheca, exothermal process when further left room is melted in representative preferably instructs the time length that melts, and can avoid the generation of left room esophagus fistula complication.
3. be provided with the current potential of six electrode mapping diverse locations, can help to melt determining of target spot, can replace complexity on some degree, wound is arranged, expensive coronary sinus electrode, the latter must enter from subclavian vein, and wound is arranged, and cost is big, complicated operation.
