Example Embodiment

[0015] Example 1

[0016] like figure 1 As shown, the stent of this embodiment is composed of three memory alloy straight cylindrical grid stent monomers 1, 2, and 3 to form a Y-shaped segmented bifurcated stent, and one end of the three-segment stent is connected with surgical suture 4. Together, an angularly adjustable movable connection region 5 is formed. The surface of the stent monomer is soaked with liquid polymer material for coating. The preparation method of this embodiment is to connect the ends of the three stent monomers with flexible wires until all the ends of the three stent monomers are connected, and the connection method is a mesh. In this embodiment, the three-section bracket monomers are on the same plane, and the angle between the bracket monomer 1 and the bracket monomer 2, and the bracket monomer 2 and the bracket monomer 3 is about 135 degrees (considering the connection position Mobility, the angle is adjustable within a certain range), the angle b...

Example Embodiment

[0021] Example 2

[0022] The bracket of this embodiment includes three bracket monomers, wherein two bracket monomers are connected at an angle of 60 degrees to form a plane, and the other bracket monomer forms an angle of 10 degrees with the plane, and one end of each segment is used together The filaments join together to form a bifurcated structure.

[0023] The ends of the three stents can be deformed into bell mouths or other shapes to prevent the stent from slipping in the cavity.

[0024] This embodiment can well solve the situation that the trigeminal affected parts of the patient are not on the same plane, and is well adapted to the individual situation of each patient.

Abstract

The invention discloses a segmented bifurcated bracket, which comprises more than three bracket monomers, and the bracket monomers are connected by wires or soft wires, wherein at least one bracket monomer forms a component with other bracket monomers. fork structure. In the present invention, the wire can be a metal wire or a non-metal material. In the present invention, further, the wire is surgical suture or memory alloy wire. In the present invention, the stent monomer has three sections, and one end of each section is connected together with a wire material to form a bifurcated structure. The invention has a simple structure, is easy to implement, can well adapt to changes in human body angles, and is suitable for dilation of bifurcated trachea or narrow bifurcation or closure of fistula. The size of each part of the segmented monomer can be spliced ​​according to clinical needs, the segmented monomer can be easily stocked, the demand for molds is small, and it is easy to produce and process.

Description

technical field [0001] The invention relates to a medical stent for digestive tract or trachea, in particular to a segmented bifurcated device for expanding bifurcated trachea or stenosis with bifurcated parts. Background technique [0002] If the branch trachea and carina are narrow or have fistula, the clinical choice is to use an integrated bifurcated stent (ie inverted Y-shaped stent), but the angle between the left and right branches of the traditional integrated bifurcated stent is relatively fixed, and the angle cannot be adjusted. If it is below 60°, it cannot conform to human organs well. However, the situation in human organs is ever-changing, especially for human trachea with pathological changes, only based on the one-piece bifurcated stent with a fixed angle, long-term use may easily cause the patient's organs to become unsuitable, and more serious may cause secondary injuries. Moreover, the mold size of the integrated bifurcated bracket is relatively fixed, an...
