Embodiment 1

[0038] When the present invention is in use, the medical staff takes out a single access bracket according to the usage requirements, and rotates the adjustment bolt 8 through medical tweezers, so that the adjustment bolt 8 rotates and drives the adjustment wire 6 to wind up or unwind, so that the adjustable bracket 1 will 6 is retracted or unwound to shrink or expand, because the inner wall of the adjustable bracket 1 located at the upper end of the adjustment slot 2 is uniformly provided with a V-shaped groove that is convenient for shrinkage adjustment, so that the adjustable bracket 1 can be quickly shrunk to achieve intervention For the one-way adjustment of the bracket, the medical personnel can adjust the adjustment bolt 123 at the same time, so that the adjustment bolt 123 drives the adjustment rope 121 to shrink or release the wire, so that the entire fixed adjustment cylinder 11 is contracted or expanded, so that the fixed adjustment cylinder 11 can be connected with t...

Abstract

The invention discloses an intravascular adjustable interventional stent which comprises an adjustable stent body, a guide plate, an adjusting line, an adjusting bolt, a fixed adjusting cylinder and acylinder adjusting assembly; wherein a sealing protection ring is fixed at one end of the adjustable support, and a fixed adjusting cylinder is fixed at the other end of the adjustable support. The adjusting bolt rotates to drive the adjusting wire to be wound or unwound, so that the adjustable support can contract or expand due to winding or unwinding of the adjusting wire; and due to the fact that the inner wall, located at the upper end of the adjusting slotted hole, of the adjustable support is evenly provided with the V-shaped grooves facilitating contraction adjustment, the adjustable support can rapidly contract, and thereby one-way adjustment of the interventional support is achieved. According to the invention, the adjusting bolt is adjusted to drive the adjusting rope to contract or release, so that the whole fixed adjusting cylinder contracts or expands, the fixed adjusting cylinder and the adjustable bracket can be adjusted together, and the whole interventional bracket issmooth and smooth.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an intravascular adjustable interventional stent and a method for using the same. Background technique [0002] A blood vessel is a series of tubes through which blood flows. Except for the cornea, hair, nails, dentin, and epithelium, blood vessels spread throughout the body. Blood vessels are divided into three types according to their structure and function: arteries, veins and capillaries. [0003] Blood vessels are the channels through which organisms transport blood, and can be divided into arteries, veins, and capillaries according to the direction of transport. Arteries bring blood from the heart to body tissues, veins bring blood back to the heart from tissues, and microvessels connect arteries and veins, which are the main places for material exchange between blood and tissues. Various organisms have different types of blood vessels. Open circulat...
