Abstract
The utility model discloses a tectorial membrane trachea stent. The trachea stent is a straight pipe notch-shaped trachea stent, and the lower mouth (4) of the straight pipe stent is symmetrically concave to form a notch (7). A furcate trachea and bronchus stent (9) is formed by the connection of an upper segment (10) and two furcate lower segments (11). The upper trachea part or the upper bronchus part is composed of a six-edge or 8-edge zigzag frame, and the furcate bronchus part of the frame is composed of a five-edge or six-to-seven-edge zigzag frame. An L-shaped trachea stent is formed by the L-shaped connection of two straight pipe stents. With the advantages of strong holding power, light foreign body sensation and recoverability, the trachea stent of the utility model can prevent the tissue from growing towards the inner part of the stent and can seal an orificium fistulae. Owing to the diversity of the utility model, stents of different forms are provided according to different focuses, which is favorable to the recovery of the focuses.
Description
Affiliated technical field
This utility model relates to the support of medical apparatus and instruments, is specifically related to the overlay film trachea bracket.
Background technology
The overlay film trachea bracket encloses into circle after by the Z-shaped bending of medical stainless steel silk, two-end-point welds or rivets with stainless steel tube, several Z type circles are with the high intensity line connection or be welded into skeleton, inside and outside skeleton, make again coated with macromolecule membrane, this stent support power is strong, foreign body sensation is light, can prevent that tissue from growing in support.But present overlay film frame form is single, can not satisfy the treatment demand of multiple focus.
Summary of the invention
The purpose of this utility model is: a kind of overlay film trachea bracket is provided, and this support divides various ways, selects multi-form support for use according to focus, shortens treatment time, alleviates patient's misery.
Technical solution of the present utility model is: this trachea bracket is a straight tube recess shape trachea bracket, the end opening symmetry of straight tube support depression, the rack side wall thorn that slips of setting up defences
Further technical scheme of the present utility model is: this trachea bracket is Y-shaped trachea and bronchial stent, be formed by connecting by 3 straight tube shape supports, epimere trachea or bronchus part are made up of the Z-shaped skeleton on 6 limits or 8 limits, and the bronchus part of its bifurcated is made up of the Z-shaped skeleton on 5 limits or limit, 6 limit to 7.
Technical solution of the present utility model can also be: this trachea bracket is L shaped tracheal bronchus support, by 2 in a certain angle being formed by connecting of straight tube shape support.
This utility model is simple in structure, and is various informative, places multi-form support according to different focuses, helps the rehabilitation of focus.

Among the figure: 1Z shape circle, 2 lines, 3 suitable for reading, 4 end openings, 5 retracting devices, 6 straight tube recess shape trachea brackets, 7 recesses, 8 agnails, 9 Y-shaped tracheas and bronchial stent, 10 epimeres, 11 hypomeres, 12L shape trachea bracket
The specific embodiment
As shown in Figure 1, straight tube shape trachea bracket encloses into Z-shaped circle 1 after by the Z-shaped bending of medical stainless steel silk, two-end-point welds or rivets with stainless steel tube, several Z-shaped circles are with 2 connections of high strength line or be welded into skeleton, inside and outside skeleton coated with macromolecule membrane such as silicone rubber, polyurethane etc. connect retracting device 5 in order to take out or to adjust support at 3 places suitable for reading of support, it is characterized in that: straight tube recess shape trachea bracket 6, end opening 4 places of straight tube support are symmetry and cave in into recess 7, one group of agnail 8 is connected on the sidewall of straight tube recess shape trachea bracket 6, end opening is near knuckle after inserting trachea, recess 7 is positioned at the two laterobronchuses place of opening the door, and can not block the ventilation of two laterobronchuses.As shown in Figure 2, Y-shaped trachea and bronchial stent, be formed by connecting by straight tube shape support, promptly the hypomere 11 by epimere 10 and two bifurcateds connects to form, epimere 10 tracheas or bronchus part are made up of the Z-shaped skeleton on 6 limits or 8 limits, and the hypomere 11 bronchus part of its bifurcated is made up of the Z-shaped skeleton on 5 limits or 6 to 7 limits.
As shown in Figure 3, L shaped trachea bracket 12, by 2 L-shaped being formed by connecting of straight pipe type support, the prominent face of junction can have membrane sealed or perforate, for stifled fistula or keep laterobronchus is ventilated.
This utility model stent support power is strong, foreign body sensation is light, can prevent that tissue from growing in support, can seal fistula mouth and recyclable, especially can select multi-form support for use according to the focus situation, helps patients ' recovery.
