Abstract
The utility model belongs to the field of medical instrument technology, provides a kind of silicon stent, including rack body, m the first flanges and n the second flanges；First flange one end is connected with the rack body proximal end, and other end edge favours rack body sidewall direction and extends outwardly；Second flange one end is connected with rack body distal end, and other end edge favours rack body sidewall direction and extends outwardly；The m and n is the natural number more than 1.The utility model is by being arranged the first flange and the second flange, so that silicon stent is after merging patient throat, both ends can touch air flue inner wall, to play guide functions to fluid, increase the throughput flowed through from rack bore, souring is risen to mucus, effectively rack bore can be avoided to block.
Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to a kind of silicon stent.
Background technology
When people breathes, air transtracheal and bronchus enter lung, because the lesions such as inflammatory granuloma, wound, tumour cause
Tracheae and bronchiostenosis, can cause the symptoms such as obstructive pneumonia, expiratory dyspnea, it is serious may threat to life.Tracheae
Holder merging is one of the important means for the treatment of airway constriction, and most widely used at present is by materials systems such as Ultimum Tis
At metallic support.Compared with metal material, preparing trachea bracket using medical silicone material has many advantages, such as：Due to material
It is soft, elastic good, it can accomplish lossless merging, original shape can be quickly recovered to after placement, and facilitate taking-up；Biofacies
Capacitive is good, and the stimulation generated to human body is small.
Existing silicon stent is usually all the fixed tubular structure of diameter, after silicon stent is placed in laryngeal pathological process position,
Mucus flows through rack bore and be easy to cause accumulation, and blocks rack bore herein.
Utility model content
The utility model provides a kind of silicon stent, for being easy because of mucus after solving silicon stent merging patient throat
The problem of accumulating and blocking rack bore again.
One of the utility model is designed to provide a kind of silicon stent, including rack body, m the first flanges and
N the second flanges；First flange one end is connected with the rack body proximal end, and other end edge favours rack body side wall
Direction extends outwardly；Second flange one end is connected with rack body distal end, and other end edge favours rack body side
Wall direction extends outwardly；The m and n is the natural number more than 1.
Further, there is the first opening, described adjacent two second convex between two adjacent first flanges
There is the second opening, the line and the rack body axis between first opening and the second opening are in angle between edge.
Further, multiple anti-skid studs are additionally provided on the rack body outer wall.
Further, first flange, the second flange are identical with height of multiple anti-skid studs on rack body outer wall.
The utility model is by being arranged the first flange and the second flange so that and silicon stent is after merging patient throat, and two
End can touch air flue inner wall, to play guide functions to fluid, increase the throughput flowed through from rack bore, to viscous
Liquid plays souring, effectively rack bore can be avoided to block.
Description of the drawings
Fig. 1 is the front view of silicon stent in the utility model.
Fig. 2 is the structural schematic diagram of silicon stent in the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Mode, the present invention will be further described in detail.
In this specification, silicon stent is defined during being placed in patient throat, is proximal end by proximal operator one end, it is separate
Operator one end is distal end.
With reference to figure 1, Fig. 2, the utility model first embodiment provides a kind of silicon stent 1, including rack body 11, m
A first flange 12 and n the second flanges 13；Described first flange, 12 one end is connected with 11 proximal end of the rack body, another
End extends outwardly along the direction for favouring 11 side wall of rack body；Described second flange, 13 one end and 11 distal end of the rack body
It is connected, other end edge favours 11 sidewall direction of rack body and extends outwardly；The m and n is the natural number more than 1；Multiple
One flange 12 is respectively formed flare openings in 11 proximal end of rack body, multiple second flanges 13 in 11 distal end of rack body.
It should be noted that the m and n may be the same or different.In the present embodiment, the m and n are 2.
This programme is by being arranged the first flange and the second flange so that silicon stent is after merging patient throat, both ends energy
Air flue inner wall is enough touched, to play guide functions to fluid, increases the throughput flowed through from rack bore, mucus is risen
Souring effectively can avoid rack bore from blocking.
Further, there is the first opening 121 between described two first flanges 12；Between described two second flanges 13
With the second opening 131, the axial direction of line and the rack body 11 between first opening, 121 and second opening 131
In angle.After the silicon stent merging patient throat of this programme, gas passage is formed between holder outer wall and air flue inner wall；Gas
From the second opening outflow after the first opening flows into the gas passage, or opened from first after the second opening flows into the gas passage
Mouth outflow；Compared with the technical solution for running parallel to rack body axis between the first opening and the second opening, this programme
So that the curved flowing of gas in the gas passage, can enhance the impetus to mucus.
Further, multiple anti-skid studs 14 are additionally provided on the rack body outer wall.This programme can effectively avoid silicone
Holder moves in air flue.
Further, the height of first flange 12, the second flange 13 and anti-skid stud 14 on 11 outer wall of rack body
It is identical.This programme is conducive to the merging of silicon stent so that the first flange, the second flange and anti-skid stud can preferably with air flue
Inner wall contacts.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
It is new to should be included in this practicality for all any modification, equivalent and improvement made by within the spirit and principles of the utility model etc.
Within the protection domain of type.
