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

Abstract

The invention relates to a medical instrument, in particular to a push rod type vascular dilator implanting tool, comprising a slide rail and a push rod axially movable and insertable in the slide rail, the rear end of the push rod is provided with a gear-rack meshing axial pushing mechanism, a spiral ferrule sleeves the push rod and is made by spiraling a special-shaped single wire, and upper and lower ends of the section of the special-shaped single wire are symmetrically provided with an upper clamping spiral and a lower clamping spiral, one end of the special-shaped single wire is fixedly connected to the front end of the push rod, and the other end of the special-shaped single wire is fixedly connected to the slide rail. The push rod type vascular dilator implanting tool is simple in structure, convenient to perform and widely applicable.

Description

technical field [0001] The invention relates to a medical device, in particular to a push rod type blood vessel dilator implantation tool. 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 s...
