At least in one embodiment, Fig. 6 show mark the one pole electrograph that records graph of heart when clamp does not closely recline with cardiac muscle through monopolar electrode multipole partly for horizontal.In addition, when the one pole electrograph demonstrates the current of injury curve, send conduit before the prompting patient avoids, this can effectively reduce the risk that myocardial perforation causes cardiac tamponade.
At least in certain embodiments, the far-end mark that constitutes when metal clamp 3 and 4 is surveyed electrode and is carried out bipolar mark when surveying as the ring electrode 5 that the near-end mark is surveyed electrode, can write down His bundle electrograph, right bundle branch, left bundle branch, the peculiar electrographs of conducting system such as general Jin Ye system.If record the distinctive electrograph of conducting system, should avoid at this place's biopsy tissue, thereby avoid damaging normal myocardium conducting system.Avoid causing the bundle branch retardance, or the risk of dissociation.
At least in certain embodiments, carry out also can carrying out when bipolar mark is surveyed the bipolar voltage mark and survey, low-voltage area is generally the cardiac muscle of pathological changes, under it instructs, helps improving the positive discovery rate of cardiac muscle biopsy.The heart muscle low-voltage area is bipolar voltage 0.15-0.5mv, and heart muscle cicatrix district is bipolar voltage < 0.15mv; The ventricular muscles low-voltage area is bipolar voltage 0.5-1.5mv, and ventricular muscles cicatrix district is bipolar voltage < 0.5mv.Because of the lobe ring is a fibrous connective tissue, bipolar mark is surveyed and is the cicatrix district, and mark is surveyed to avoiding clamp in the cicatrix district near the lobe ring.If the acquisition normal myocardium then should be surveyed at the bipolar voltage mark and cut tissue for normal zone.
At least in certain embodiments, electric physiology mark is surveyed and also can be found to cause ARR focus, excises such focus, also can treat arrhythmia.
At least in certain embodiments, the electrode of distal end of catheter is a plurality of, can in a big way, mark survey simultaneously, helps confirming to intend the position of clamping the flesh of coring fast, shortens the operating time.
Fig. 7 shows at least in certain embodiments; Biopsy forceps is through buttock line 9; Buttock line 10 is connected with electric signal process unit 39, and electric signal process unit 39 carries out filtering with the far-end clamp of biopsy forceps and the cardiac electric signals of ring electrode record, amplifies; Transfer to work station 40, and the far-end clamp of biopsy forceps and the strength signal that is used for sterically defined high frequency electric of ring electrode record are transferred to the framing signal blood processor.Localizing electrode sheet 31 is attached to the shirtfront, and localizing electrode sheet 32 is attached to back, and localizing electrode sheet 33 is attached to right oxter, and localizing electrode sheet 34 is attached to left oxter, and after localizing electrode sheet 35 was attached to neck, localizing electrode sheet 36 was attached to the left thigh inboard.Above-mentioned three counter electrode sheets are connected with rosette 37 through the insulation buttock line, and rosette 37 is accepted the high frequency location current that framing signal blood processor 38 sends.The information such as intensity of the high frequency electric that the framing signal blood processor transmits according to electric signal process unit can calculate the 3 d space coordinate at far-end clamp and ring electrode place, and transmit it to work station 40.The information of work station 40 integration cardiac electric signals, the space three-dimensional locating information can be rebuild the three-dimensional chambers of the heart that mark is surveyed, with the configuration of the three-dimensional chambers of the heart and signal of telecommunication demonstration in real time on display 41 in real time.
At least in certain embodiments, buttock line 9 is surveyed, can be marked the three dimensional structure that check weighing is built the chambers of the heart through contact when 3 D locating device is connected with electric physiology mark with buttock line 10.And the normal conduction tissue that mark is measured, low-voltage area, the cicatrix district shows on the three dimensional structure of the chambers of the heart of rebuilding.Advantageously; Biopsy forceps 1 with electric physiology mark brake can make a mark the position that cuts cardiac muscular tissue's BIAO and BEN on the three dimensional structure of the chambers of the heart of rebuilding; Avoid repeating to cut tissue specimen, thereby significantly reduce the risk of cardiac perforation in identical position.
In certain embodiments, the biopsy forceps in the above-mentioned cardiac muscle biopsy system is used for obtaining tissue samples from patient or animal hearts.After the local anesthesia, the puncture central vein comprises femoral vein, subclavian vein, and internal jugular vein, and insert the arterial sheath pipe.Biopsy forceps arrives right atrium and right ventricle along vein blood vessel through the sheath pipe under X-ray machine instructs, also can pass through atrial septal puncture, arrives left atrium and left ventricle.Through the camber of adjustment biopsy forceps far-end, and, arrive and intend the heart area that carries out biopsy along clockwise or contra solem rotary guide pipe 2.Instruct the cardiac muscle at this place whether to be fit to cut through the survey of electric physiology mark.After taking out myocardium sample biopsy forceps is withdrawn from the body, obtained tissue specimen at the external metal clamp 3 and 4 of opening.
