In the utility model, furthermore, the silk material is operation suture or memory type alloy wire. The utility model discloses in, the support monomer is the three section, and the one end of each section uses the silk material jointly to link together, forms the bifurcation structure. The utility model discloses simple structure easily realizes, and compliance human angle that can be fine changes, should be applied to branching trachea or have the shutoff of the narrow expansion in branching position or fistula. Each part size of the sectional single body can be spliced according to clinical requirements, the sectional single body can be easily prepared, the requirement on the quantity of the die is low, and the production and the processing are easy.
Description
Technical Field
The utility model relates to a medical bracket for alimentary tracts or tracheas, in particular to a sectional forked type device for expanding a forked trachea or having a forked part.
Background
The branch trachea, the carina part are narrow or have the fistula, and clinical selection uses the forked type support of integral type (i.e. fall Y type support), but the contained angle of branch is comparatively fixed about traditional integral type forked type support, and the contained angle can't accomplish below 60, can not conform to human organ well. The conditions in human organs vary, especially for the diseased human trachea, the patient organs are easy to be uncomfortable after long-term use and the secondary injury is easy to be caused by the integrated bifurcation bracket with a fixed angle. And the forked type support mould of integral type size is comparatively fixed, and the mould volume is big, is unfavorable for producing and processing.

In order to solve the technical problem, the utility model discloses a alimentary canal or trachea are with segmentation forked type support, including the support monomer more than the three section, adopt the silk material to connect between the support monomer, wherein have at least one section support monomer and other support monomers to form the bifurcation structure.
The utility model discloses in, the silk material can be nonmetal silk material or metal silk material.
In the utility model, furthermore, the silk material is operation suture or memory type alloy wire.
The utility model discloses in, the support monomer is the three section, and the one end of each section uses the silk material jointly to link together, forms the bifurcation structure.
The utility model discloses in, the contained angle scope between per two support monomers is 1 ~ 179 degree.
The utility model discloses in, all support monomers are in on the coplanar.
The utility model discloses in, another scheme has at least a section of support monomer and other support monomers not on the coplanar.
The utility model discloses in, can adopt netted or heliciform or other arbitrary connection weaving modes to connect between the support monomer. The length, thickness and other shapes of each section of the bracket can be individually adjusted according to different disease focus conditions in each patient.
The utility model discloses simple structure easily realizes, and compliance human angle that can be fine changes, should be applied to branching trachea or have the shutoff of the narrow expansion in branching position or fistula.

Drawings
These and/or other advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings and the following detailed description.
Fig. 1 is a schematic structural diagram of embodiment 1.
Detailed Description
Example 1
As shown in fig. 1, the stent of this embodiment is a Y-shaped segmented bifurcation stent composed of three memory alloy straight cylindrical mesh stent monomers 1, 2, 3, wherein one ends of the three-segmented stent are connected together by using a surgical suture 4 to form an angle-adjustable movable connection region 5. And infiltrating a liquid high polymer material on the surface of the stent monomer to carry out film coating. The preparation method of this embodiment is to connect the two-purpose flexible wires at the ends of the three stent single bodies until the ends of the three stent single bodies are completely connected, and the connection mode is a net shape. In this embodiment, three support single bodies are located on the same plane, the support single body 1 and the support single body 2, the included angle between the support single body 2 and the support single body 3 is about 135 degrees (considering the mobility of the connection part, the included angle is adjustable in a certain range), and the included angle between the support single body 1 and the support single body 3 is about 90 degrees.
The use method of the embodiment comprises the following steps:
the guide wire is fed into the oral cavity of the human body to reach the focus;
the introducer is fed along the guidewire and the stent is released after reaching the site. The implanter may be a Y-stent implanter as is common in the art.
The inner tube of the imbedding device and the split type forked stent are bound and fixed by a wire, the outer tube of the imbedding device is withdrawn after the position is reached, then the position is finely adjusted, and the stent is released by pulling the wire after the position is well fixed. The foreign body forceps, the bracket taking-out hook and the like can be taken out at the later stage.
Example 2
The support of this embodiment includes three sections support monomers, and wherein two support monomers are 60 degrees contained angles and connect and constitute a plane, and another support monomer constitutes 10 degrees contained angles with this plane, and the one end of each section uses the silk material jointly to connect together, forms the bifurcation structure.
The ends of the three bracket single bodies can be deformed into a bell mouth or other shapes, so that the bracket is prevented from slipping off in the cavity.
The embodiment can well solve the problem that the affected parts of the three forks of the patient are not on the same plane, and is well suitable for the individual condition of each patient.
The utility model provides a branching type support, the method and the way of specifically realizing this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to ordinary skilled person in this technical field, not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also be regarded as with moist decorations the utility model discloses a protection scope. All the components not specified in the present embodiment can be realized by the prior art.
