In the surgical procedure of calcification score, the operation of coronary guide wire (referring mainly to PTCA seal wire herein) (such as seal wire in place,Seal wire resetting, seal wire technology of driving in the wrong direction, seal wire protection, seal wire anchoring etc.) it is core technology step, and with calcification score technologyIt is more and more mature, it is also increasingly common and universal to the interventional therapy of the complex lesions such as multi-vessel lesion, bifurcated lesions, CTO lesion.
When handling above-mentioned complex lesions, generally require to be built into more coronary guide wires to coronary artery by guiding catheter, oneThe case where the case where being placed in 3 coronary guide wires in root guiding catheter simultaneously is very universal, 4 seal wires is quite a few to see.Patient is locatingIn the case where managing more seal wires, many problems are often encountered, dose of radiation and contrast agent, operating time is caused to be obviously prolonged,Damage the health benefit of patient and doctor itself.
The coronary guide wire appearance of different manufacturers is often similar, and is possible to the patient in certain operation and single variety is used onlyCoronary guide wire (seal wire appearance is just the same).In frequent operation when these seal wires being exactly like in appearance, because patient needs to divert one's attention togetherThe case where walking operation inspection platform, concern vital sign patient, observation display screen, therefore forgeing certain root seal wire place vessel branch is non-Usually see, patient generally requires by pulling conductive filament head end movement under certain root or more seal wires and Synchronous display screen at this timeSituation judges the ownership of seal wire, not only increases operating time, also increases the dosage of x-ray radiation, increases patient's radiographyThe usage amount of agent, and the increase of contrast agent dosage can increase the risk that adverse reaction (radiographic contrast nephropathy, encephalopathy) occurs for patient.
In the case where continuous moving operations seal wire, it is possible to cause seal wire to tangle (similar to turn round fried dough twist), will cause at this timeSacculus limitation of activity, other seal wires passively mobile dislocation the case where, patient, which generally requires to devote a tremendous amount of time, to withdraw from entanglement and leadsSilk simultaneously resets seal wire, the step also inevitable increase with X-radiation, contrast agent usage amount.
Coronary guide wire has smooth surface, is not easy rubs mutually.But works as and be sent into along seal wire or exit sacculus, microtubular etc.When, the crowded mutual frictional force of content that will lead to inside guiding catheter increases, and sacculus and microtubular increase and not very smoothFriction surface also will increase frictional force so that there is the possibility that is passively displaced in other seal wires.Seal wire is passively displaced possibilityCause two kinds of consequences: passive recession will lead to seal wire dislocation, need to reset the seal wire (increasing that inevitable collateral radiation and contrast agent useAdd)；It is sent before passive and will lead to wire tips impact coronary artery blood vessel distal end, it is possible to led to coronary branches rupture haemorrhage, or even drawSending out dangerous pericardial tamponade may.And assistant needs to divert one's attention to operate three Three-way injectors, pressure pump, examination couch, concernVital sign and screen, the instrument that makes arrangements for surgery etc., it is difficult to seal wire persistently be auxiliarily fixed.
