Abstract
The utility model provides an easily-controlled start guide wire, which comprises a far end (1), a middle segment (2) and a near-end pushing segment (3), and is characterized in that the cross section of the near-end pushing segment (3) is in a polygonal shape, such as a triangle, a square, a hexagon or an octagon. The easily-controlled start guide wire obviously increases the controllability when a guide wire is twisted, can twist micro angles more easily, and is convenient for entering target vessels.
Description
Technical field
This utility model belongs to technical field of medical instruments, especially a kind ofly is used for inserting that thing puts in place and the startup seal wire of guide catheter operation in blood vessel.
Background technology
Starting seal wire and be extensive use of in conduit conveying and some other interventional procedures, is the seal wire commonly used of cerebral angiography and angioplasty.Its structure can be divided into the soft head end of far-end, and interlude and near-end push section.The effect of seal wire is exactly to be built in the conduit, in the guide catheter target approach blood vessel, because target blood often has certain rotation, distortion and angled, therefore in the guide catheter intravasation, often need earlier seal wire is sent in the blood vessel, at this moment need repeatedly, meticulous, minute angle reverse seal wire and with the advance and retreat operation, but because seal wire diameter tiny (0.89mm), it is circular that the near-end of existing seal wire pushes the section cross section, reverses difficulty.Especially use the superslide seal wire, have sterile gloves, Chang Wufa reversed when blood vessel was tortuous, perhaps can not arrive suitable angle, caused operating time to prolong, and may cause injured blood vessel.
Summary of the invention
The purpose of this utility model provides the strong easy-operating easy control of a kind of controllability and starts seal wire.Technical solution adopted in the utility model is: this utility model includes far-end, interlude and near-end and pushes section, it is characterized in that the cross section of near-end propelling movement section is a polygon, for example: triangle, square, hexagon or octagon.
This utility model obviously increases the controllability when reversing seal wire, can more easily carry out reversing of trickle angle, is convenient to the target approach blood vessel.

The specific embodiment
With reference to accompanying drawing, this utility model includes far-end 1, interlude 2 and near-end and pushes section 3, it is characterized in that the cross section of near-end propelling movement section 3 is a polygon, for example: triangle, square, hexagon or octagon.
Claims (4)
1, a kind of easy control starts seal wire, includes far-end (1), interlude (2) and near-end and pushes section (3), it is characterized in that the cross section of near-end propelling movement section (3) is a polygon.
2, start seal wire according to the said easy control of claim 1, it is characterized in that the cross section of said near-end propelling movement section (3) is a triangle.
3, start seal wire according to the said easy control of claim 1, it is characterized in that said near-end pushes the cross section of section (3) for square.
