Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related in blood vessel intervention operation a kind of Ink vessel transfusing blood pressure used
Measure seal wire.
Background technology
The myocardial ischemia that coronary stricture causes, needs ischemia relevant diseases blood vessel is carried out myocardial revascularization.And really
Before determining myocardial revascularization strategy, it is necessary first to find the evidence of conclusive ischemia.At present, simple coronary angigraphy is clearly drawing
Playing criminal's pathological changes aspect of ischemia, especially for the middle pathological changes on iconography, there is limitation in tradition coronary angiography.And by
In the uncertainty that this kind of limitation causes, intervention doctor may be misled and go to process the stenotic lesion without clinical meaning, cause
Degree medical treatment, or ischemia relevant blood vessel is not processed in time, cause patient not obtain effective treatment.
Since the nineties in 20th century, Nico Pijls and De Bruyne proposition calculates the new of coronary blood flow by piezometry
Index blood flow reserve mark (Fractional Flow Reserve, FFR), through long-term basic and clinic studies, FFR
The most gradually replace tradition coronary angiography, become " the gold mark of coronary stenosis Evaluation of Functional (having the stenotic lesion of clinical meaning)
Accurate ".Conventional FFR assessment can reduce unnecessary intervention intervention, and can improve the long-term prognosis of patients with coronary heart disease.
Blood flow reserve mark (FFR) refers in the case of coronary artery exists stenotic lesion, and this blood vessel is supplied cardiac muscle district
The obtainable maximum blood flow in territory can be obtained with the ratio of maximum blood flow the most under normal circumstances with the same area.FFR mainly leads to
Crossing and calculate the ratio of coronary stricture remote pressure and aortic root pressure and obtain, narrow remote end pressure can pass through pressure
Seal wire records when maximum irrigates blood flow (in by arteria coronaria or intravenous injection papaverine or adenosine or ATP).FFR=Pd/Pa
(Pd is the aortic pressure that guiding catheter is measured, and Pa is the coronary stenosis remote pressure that Pressure wire is measured).Normal visceral pericardium hat
Shape tremulous pulse is the least to the resistance of blood flow, and the normal value of FFR is 1.0；In the presence of Epicardial coronary arteries has stenotic lesion, FFR < 1.0.
FFR=0.60, illustrates 60% when the blood supply of this arteria coronaria only has normal.FFR has the threshold value being apparent from, and FFR ＜'s 0.75 is narrow
Nearly all can cause myocardial ischemia, FFR >=0.75 narrow, the probability causing myocardial ischemia is the least.
Operation is simple in the measurement of FFR, has the highest repeatability, and FFR pressure measxurement seal wire almost can be as often
Rule interventional guide wire uses, and will not too much increase difficulty and the time of interventional therapy.
Clinically, pressure measxurement seal wire is mainly by means of the pressure transducer blood pressure by criminal's pathological changes being placed in far-end
Being converted into the signal of telecommunication, then the circuit by being connected with sensor is delivered to receive terminal and calculate FFR numerical value, Yi Jizuo
For conventional interventional guide wire, with coordinating of other intervention apparatus (such as: foley's tube, mounting system, microtubular etc.).Therefore, pressure
Power measures seal wire needs the structure considering himself to ensure the connectedness of circuit in design and manufacture, it is to avoid during use
Occur that short circuit affects measurement result.Meanwhile, the good transition of composition seal wire each several part will strengthen Ink vessel transfusing blood pressure measurement seal wire
Matching as conventional interventional guide wire with other intervention apparatus.
