In this utility model, because electrode slice 2 will abut in heart surface or around vessel outer wall, thereby its shape and size need sighting target to survey the situation at position and formulate.Every cube electrode sheet 2 is provided with aperture 3, and the diameter of aperture 3 designs according to actual needs, generally can be 0.8mm-1.2mm, can be used for sewing up in the operation.
In this utility model, electrode points 1 arranging on electrode slice 2 can be adopted forms such as rectangle or honeycomb array.The electrode points of the former adjacent two row is vertically aimed at (seeing accompanying drawing 2) one by one; The electrode points of adjacent two row of the latter becomes 60 ° to stagger up and down, and adjacent two electrode points of the lastrow electrode points corresponding with next line constitutes equilateral triangle (seeing accompanying drawing 3).When electrode slice was irregularly shaped, the electrode points array will correspondingly be adjusted.
In this utility model, electrode slice 2 connects the current potential detecting instruments by connector 6.
Conventional epicardial potential mapping adopts bipolar assignment test method, promptly represents the electrical activity in a certain zone of exterior heart surface with the mapping signal difference in two sites.This method defective is to survey less than myogenetic depolarization of adjacent cells territory heart and conduction, thereby has influence on the comprehensive and degree of accuracy of mapping.The mapping electrode of this utility model design can be realized single bipolar compound mapping easily, and concrete grammar is as follows:
Each electrode points can provide one pole mapping signal one.And adjacent two electrode points can form bipolar lead in the electrod-array, are about to the bipolar signal of the mapping signal difference of adjacent two electrode points as site among both.Capable for m, the rectangular array form (seeing accompanying drawing 2) of n row, can obtain unipolar signal quantity in the mapping process is the mn road, and bipolar signal quantity is the 2mn-m-n road; For honeycomb array format (seeing accompanying drawing 3), bipolar signal quantity is 3mn-2 (m+n)+1 road.
The electrode slice of this utility model design can be used for the electrical mapping of biological tissues such as heart, brain stomach function regulating.Electrode slice can be made into corresponding shape according to the situation for the treatment of the mapping position.
The beneficial effects of the utility model:
1. pellet electrode can carry out the synchronous mapping in a large amount of sites.Several plate electrodes cooperate synchronous, the real-time and three-dimensional current potential mapping that can finish whole heart.
2. electrod-array and lead-in wire are by becoming one of flexible printed circuit sheet structure.The electrode softness, but not frangibility, come off, easy to use, the reliability height.
3. the array structure of electrode points and single, double utmost point method of signal multiplexing have greatly improved the utilization rate of electrode points.
4. electrode points is equidistantly arranged, and size is accurate, can calculate the information such as direction, speed and path of depolarization ripple at the mapping regional spread according to each unipolar signal.This has outstanding meaning to complicated ARR researchs such as atrial fibrillation, diagnosis.
