Segmental fork type bracket

Abstract

The invention discloses a segmental fork type bracket. The bracket comprises three or more segments of single bracket bodies which are connected by wires or flexible cords, and at least one single bracket body forms a fork structure with the outer single bracket bodies. In the segmental fork type bracket, all the wires can be metal wires or can also be non-metal wires; further, the wires are surgical suture lines or memory alloy wires; one end of each of the three single bracket bodies is connected by wires to form the fork structure. The segmental fork type bracket is simple in structure, easy to implement, capable of well adapting to the angle change of the human body and suitable for being applied to expansion of fork trachea or narrow devices with fork parts or blockage of orificium fistulae. All parts of each single bracket body can be spliced according to clinical needs, the single bracket bodies can be easy to prepare, produce and process, and the quantity of required molds is small.

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...

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, and the mold quantity is large, which is not conducive to production and processing
