Problems solved by technology
[0003] The existing hypotube expands and fixes the heart stent at the lesion position through the balloon during use, thereby completing the delivery of the heart stent, but the existing hypotube cannot adjust the heart stent after the heart stent is installed , heart stents are prone to instability, and secondly, the existing hypotubes are inconvenient to apply medicine to the lesion, and the hypotubes are easily blocked in the arteries, and the penetration is average. Therefore, we propose a Alloy-coated hypotube for cardiac stent delivery

The invention discloses an alloy coating hypotube for heart stent delivery, and relates to the field of medical instruments, the alloy coating hypotube comprises a hypotube body and a heart stent body, and the hypotube body is located in the middle of the heart stent body. According to the alloy coating hypotube for heart stent delivery, when the medicine applying ring is used, liquid medicine can be delivered through the medicine applying tube, when the medicine applying ring is used, the liquid medicine can flow out through the leakage hole, medicine applying can be conveniently conducted on a lesion site, treatment can be conveniently conducted, a second air bag can be inflated through a second air tube when the second air bag is used, and the medicine applying ring is convenient to use. The heart stent body can be adjusted and fixed after expansion is completed, the stability of the heart stent body can be improved, the conveying success rate of the heart stent body can be increased, the penetrating ring can have the penetrating effect on the artery blood vessel in the using process, the hypotube body can move forwards in the artery blood vessel more conveniently, and the heart stent body is more convenient to use. When the cleaning teeth are used, blockages in arterial blood vessels can be cleaned, and the effect of dredging the arterial blood vessels can be achieved.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to an alloy-coated hypotube for cardiac stent delivery. Background technique [0002] Cardiac stent, also known as coronary artery stent, is a commonly used medical device in cardiac interventional surgery. It has the function of dredging arteries. The development process of the absorbing stent, in the process of cardiac stent delivery, it is necessary to use the hypotube to send it to the designated position. [0003] The existing hypotube expands and fixes the heart stent at the lesion position through the balloon during use, thereby completing the delivery of the heart stent, but the existing hypotube cannot adjust the heart stent after the heart stent is installed , heart stents are prone to instability, and secondly, the existing hypotubes are inconvenient to apply medicine to the lesion, and the hypotubes are easily blocked in the arteries, and the penetration is average. There...
