Problems solved by technology

However, due to the one-piece fixed structure of the support rod, it is very difficult to install and release the two ends of the monofilament on the support rod, and it is easy to bring out the half-released monofilament during the process of pulling out the support rod, resulting in failure of the operation

Description

technical field [0001] The invention relates to a medical device, in particular to a surgical tool for implanting a blood vessel dilator. Background technique [0002] At present, the commonly used cardiovascular dilation surgery is mainly to install stents or balloons. Since the cardiovascular pipeline is relatively thin, the operation during the operation is very troublesome. It takes a lot of time and energy to install and adjust the position of the stent, which brings difficulty and risk to the operation. Chinese patent 2010202319042 discloses a "cardiovascular dilation device" in which the mesh stent is installed in a guide tube in advance, and a stylet is also installed in the guide tube. During the operation, the guide tube is first implanted into the blood vessel, and then Use the die to push out the mesh support. Although this "cardiovascular dilation device" can simplify the operation to a certain extent and improve the accuracy of the mesh stent in place, its sc...
