Description

Pen is melted in epicardial fat pad location

Technical field

The invention belongs to technical field of medical equipment, relate to a kind of epicardial fat pad location and melt pen.

Background technology

At present, locate heart epicardial fat pad in cardiac operation and zoopery and be divided into Anatomical orientation and tissue positioned two kinds of methods, but there is individual variability in Anatomical orientation, and unreliable, and need tissue positioned fat pad, tissue positioned concrete grammar is:

1. stimulating electrode tail end connects stimulation instrument, there will be heart rate and declines, blood pressure drops after navigating to fat pad.2. need to change electrophysiology instrument ablating electrode after locating fat pad position to melt.But fat pad position, original stimulating electrode location is owing to can not to mark labelling at epicardial fat pad after replacing ablating electrode, the memory of naked eyes is needed to locate, may fat pad deviations and melt the halfway situation of fat pad after replacing ablating electrode, the undesirable of surgical effect can be caused.This method of repeatedly locating fat pad is melting the lengthy and tedious complexity of fat pad mode operation process, the generation that malignant arrhythmia also may be caused to quiver as room after repeatedly stimulating location.

Summary of the invention

The object of this invention is to provide a kind of epicardial fat pad location and melt pen, the difficulty melting target spot and be difficult to determine and easily occur to be shifted can be solved in current epicardial fat pad ablation procedure, overcome existing fat pad and melt in mode process the situation of repeatedly locating and malignant arrhythmia easily occurring after fat pad, not needing again to change ablating electrode while Intraoperative position fat pad, the malignant arrhythmia event brought because repeatedly locating fat pad can being reduced.And reduce repeatedly heart epicardial fat pad location and melt caused complication.

The technical solution adopted in the present invention is; pen is melted in a kind of epicardial fat pad location; comprise the shaft of a writing brush; inside, shaft of a writing brush front end is provided with pen core; the end of pen core is connected by the plate washer of spring with shaft of a writing brush inside; the head end of pen core is provided with can bend fixing pipe arbitrarily; ablating electrode head, silver ring electrode are arranged on can arbitrarily in bend fixing pipe; stimulating electrode negative pole is connected with silver ring electrode by protection switch; ablating electrode front end is connected with ablating electrode head, and stimulating electrode positive pole is connected with ablating electrode head.

Feature of the present invention is also, ablating electrode head is arranged on can bend fixing pipe die place arbitrarily, and silver ring electrode is arranged on outside ablating electrode head.

Insulant is provided with between silver ring electrode and ablating electrode head.

Ablating electrode end connects ablatograph.

The invention has the beneficial effects as follows that synchronously can locate fat pad carries out melting melting of fat pad, the process that simplification cardiac operation and the dirty fat pad of animal experimental center melt simultaneously, improve the accuracy of location, effectively reduce the generation of malignant arrhythmia.

Fig. 2 is the side view of Fig. 1.

In figure, 1. silver ring electrode, 2. ablating electrode head, 3. insulant, 4. pen core, 5. protection switch, 6. spring, the 7. shaft of a writing brush, 8. can bend fixing pipe, 9. stimulating electrode negative pole, 10. stimulating electrode positive pole arbitrarily, 11. ablating electrodes.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Pen is melted in a kind of epicardial fat pad location, structure is as Fig. 1, shown in Fig. 2, comprise the shaft of a writing brush 7, inside, the shaft of a writing brush 7 front end is provided with pen core 4, the end of pen core 4 is connected with the plate washer of the shaft of a writing brush 7 inside by spring 6, the head end of pen core 4 is provided with can bend fixing pipe 8 arbitrarily, ablating electrode head 2, silver ring electrode 1 is arranged on can arbitrarily in bend fixing pipe 8, wherein, ablating electrode head 2 is arranged on can bend fixing pipe 8 die place arbitrarily, silver ring electrode 1 is arranged on outside ablating electrode head 2, isolated by insulant 3 between silver ring electrode 1 and ablating electrode head 2, namely ablating electrode head 2 and silver ring electrode 1 form two concentric electrodes at pen core 4 head end, concentric circular inner circle is ablating electrode head 2 and as of stimulating electrode, concentric circular cylindrical be silver ring electrode 1 as stimulating electrode another.Stimulating electrode negative pole 9 is connected with silver ring electrode 1 by protection switch 5, and ablating electrode 11 front end is connected with ablating electrode head 2, and ablating electrode 11 end connects outside ablatograph.Stimulating electrode positive pole 10 is connected with ablating electrode head 2.

Pen core 4 head end is against for surveying fat pad position, and due to heartbeat, spring 6 can alleviate the impact of heartbeat on style of writing point.After opening breast, some fat pad position might not be can see under direct-view, can the convertible any flexibility of bend fixing pipe 8 arbitrarily, regulates written angle.Press protection switch 5, start to stimulate.After finding that heart rate reduces, unclamp protection switch 5, open ablatograph, directly melt.

In form of a stroke or a combination of strokes insulation crust; stimulating electrode and ablating electrode are integrated into a nib; in the shaft of a writing brush, be designed with stimulating electrode protection switch, respectively stimulating electrode, ablating electrode connected electric stimulating instrument, ablatograph at shaft of a writing brush rear portion, adjustment stimulation instrument and ablatograph suitable parameters.Stimulating electrode pins stimulating electrode protection switch before opening; at this moment just give electricity irritation and ablating electrode owing to having the unlatching of protection switch and inoperative; when occurring showing fat pad accurate positioning after HRV index declines; unclamp stimulating electrode protection switch; do not move nib to be namely converted to ablation mode and to start fat pad and melt, at this moment stimulating electrode is closed condition and inoperative.From location fat pad to melting under the help of pen is melted in fat pad location, nib does not leave heart surface all the time, there will not be in originally melting, owing to changing ablating electrode, deviations situation occurs, stimulating electrode melts behind location at once, and accurate positioning is melted thoroughly.
