Abstract
The utility model discloses a non-blood vessel chamber says seal wire, including the core silk, core silk head end is provided with soft head, core silk, soft head are provided with the package outward and mould the layer, core silk head end, soft head have the tapering, and soft head and core silk head end all have certain tapering, through the size of control tapering, can realize the different soft or hard degrees at the different positions of soft head, and at the operation in-process, the soft head of front end of non-blood vessel chamber way seal wire has the tapering, can make the seal wire have good guidance quality to the relative rear end of the soft head of seal wire is more delicate, avoids damaging the tissue.
Description
Technical field
This utility model relates to a kind of tract seal wire, and specifically a kind of non-vascular tract seal wire, belongs to technical field of medical instruments.
Background technology
The non-vascular tract seal wire of current use is mainly made up of core silk (Nitinol), plastic coating (politef) and soft head (polyurethane, tungsten, hydrophilic coating).Wherein soft head is the same with the size of the maximum outside diameter of seal wire, in using, if select larger-diameter seal wire, may cause seal wire predetermined position more difficult to get access, and the hardness of soft head does not change, easy damaged tissue.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of seal wire with the soft head of good guidance quality, when not damaged tissue, guarantees that seal wire can arrive predetermined position smoothly.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of non-vascular tract seal wire, comprise core silk, described core silk head end is provided with soft head, and described core silk, soft head are outside equipped with covered plastics layer, and described core silk head end, soft head have tapering.
The material of described core silk is dilval.
The material of described covered plastics layer is politef, is the zebra spiral lines of 2 kinds of different colours outside covered plastics layer.
The material of described soft head is polyurethane, containing developing materials such as barium sulfate, tungsten or gold in described polyurethane.
Soft head and core silk head end all have certain tapering, by controlling the size of tapering, can realize the different soft and hard degree of the different parts of soft head.In operation process, the soft head in front end of non-vascular tract seal wire has tapering, and seal wire can be made to have good guidance quality, and the front end opposed rear end of the soft head of seal wire is more weak, avoids damaged tissue.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1, a kind of non-vascular tract seal wire, comprises covered plastics layer 1, core silk 2 and soft 3, described core silk 2 head end is provided with soft head, and as shown in Figure 1, soft 3 parts are positioned at the outer surface of core silk 2, a part is located at core silk 2 front end, and covered plastics layer 1 is arranged on core silk 2, outside soft 3.
The material of core silk 2 is dilval, and 2 head ends of core silk have tapering.
The material of covered plastics layer 1 is politef, and the outer surface of covered plastics layer 1 has the zebra spiral lines of 2 kinds of different colours.
3 materials of soft head are polyurethane, and containing developing materials such as barium sulfate, tungsten or gold in polyurethane, soft 3 has tapering.
All there is certain tapering the front end of soft 3 and core silk 2, by controlling the size of tapering, can realize the different soft and hard degree of the different parts of soft 3.
The leading exterior surface of seal wire has the hydrophilic coating of certain length.In operation process, soft 3, the front end of non-vascular tract seal wire has tapering, and seal wire can be made to have good guidance quality, and the front end opposed rear end of seal wire soft 3 is more weak, avoids damaged tissue.
Above-described embodiment limits this utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
