Recently, the 60-year-old citizen Wu Daye became a "special volunteer" in the outpatient hall of Taixin Hospital. He used his personal experience to tell the outpatients about his illness and the operation of the hospital in Taixin Hospital. The director of Sun Zhonghua who gave him an operation sent a "rejuvenation" plaque. It turned out that Uncle Wu was a patient with coronary heart disease and severe vascular calcification. Director Sun Zhonghua used the latest atherectomy technique to open a strong "barrier" in the blood vessel twice and put it into the stent to restore blood flow. A year ago, Uncle Wu’s chest pain continued intermittently for more than three months. To this end, he came to Taixin Hospital for coronary angiography. The results showed that Wu’s three major coronary arteries had diffuse stenosis with severe tortuous calcification, and the two stenosis degrees reached 95% and 99%, respectively. Due to the diffuse stenosis of the coronary arteries of Uncle Wu, it is expected that the long-term effect of surgical bypass surgery will not improve his current situation, but the blood vessels with such a severe stenosis will not have obvious effects.
In September 2016, Director Sun Zhonghua implemented coronary atherectomy and stent surgery for Uncle Wu. During the operation, Director Sun used a 1.5 mm rotary grinding head to grind the calcification barrier of the right coronary artery at a rotational speed of 150,000/min per minute to smooth the intravascular lumen, and then in the opening, proximal and middle sections of the patient's right coronary crown. Three stents were placed and the total operation time was 1 hour. In February 2017, when Uncle Wu returned to the hospital to review the effect of the stent, he also performed the rotation of the left anterior descending artery and inserted two stents in the stenotic position. The symptoms of angina were basically disappeared, and the quality of life basically reached the pre-morbid state. .
Director Sun Zhonghua explained that severe coronary calcification is a layer of hard material on the wall of the arterial wall, which is equivalent to heavy barriers. Ordinary interventional surgery can not expand the blood vessels. Only the rotating head with high speed is used to cut the plaque and open the barrier. In order to ensure the smooth follow-up. Rotary grinding is an olive-shaped rotary grinding head with diamond particles. According to the theory of "differential cutting", the calcified or fibrotic arteriosclerotic plaque is selectively removed, and the elastic vascular tissue is rotated at a high speed. When the head passes, it will automatically bounce off, that is, the atherectomy head does not cut the elastic tissue and the normal coronary artery, and will not damage the normal blood vessels. After atherectomy, the plaque will be polished to a smaller size than the red blood cells. The debris is swept away by the bloodstream to the distal end of the blood vessel and is engulfed and metabolized by human macrophages. Coronary atherectomy is an important method for the treatment of severe calcification of coronary arteries. Proper use can effectively ablate coronary artery calcification and create good surgical conditions for the final placement of coronary stents.
DM-Reflective films SeriesHIGH INTENSITY PRISMATIC GRADE are weatherproof, self-adhesive retroreflective films with an excellent corrosion and solvent resistance.The retroreflective system consists of sealed cells of air backed microprisms, using total internal reflection(see the structure drawing as below).The smooth surface PMMA shows a high scratch resistance and impact strength with the internal PMMA microprismatic layer.
