Abstract
The utility model belongs to the field of medical instrument technology, a kind of silicon stent, including rack body and multiple suckers are provided, the rack body has tubular structure, the multiple sucker is arranged on the rack body outer wall, and sucker disk is directed away from the direction of rack body.The utility model, which passes through, is arranged sucker structure so that silicon stent can be closely bonded with throat inner wall, effectively silicon stent be avoided to be displaced after merging；In addition, sucker structure increases the deformation nature of silicon stent radially, the adhesive force of holder and patient throat is further increased.
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.
In order to avoid silicon stent is displaced after being incorporated into patient throat, existing holder outer wall is at a certain distance
Some spike protrusions can be set, narrow section throat is secured the stand to by radial support power, but still not can be well solved branch
The problem of frame shifts.
Utility model content
The utility model provides a kind of silicon stent, for being easy after solving holder merging patient throat in the prior art
The problem of being displaced.
The purpose of this utility model is to provide a kind of silicon stent, including rack body and multiple suckers, the holders
Ontology has tubular structure, and the multiple sucker is arranged on the rack body outer wall, and sucker disk is directed away from holder
The direction of ontology.
Further, the length of the rack body outer wall in an axial direction is more than the length of inner wall in an axial direction, makes rack body
Both ends form the end wall with oblique angle.
The silicon stent of the utility model is by being arranged sucker structure so that silicon stent can be pasted closely with throat's inner wall
It closes, effectively silicon stent is avoided to be displaced after merging；In addition, sucker structure increases the deformation behavior of silicon stent radially
Can, further increase the adhesive force of holder and patient throat.
Description of the drawings
Fig. 1 is the structural schematic diagram of silicon stent in the utility model.
Fig. 2 is the structural schematic diagram of sucker 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.
With reference to figure 1, Fig. 2, the utility model first embodiment provides a kind of silicon stent 1, including 11 He of rack body
There is tubular structure, the multiple sucker 12 to be arranged in 11 outer wall of the rack body for multiple suckers 12, the rack body 11
On, and the opening of the sucker 12 is directed away from 11 direction of rack body.
It should be noted that the sucker 12 has disk 121 and is connected to the fixed part 122 at 121 back of disk, it is described
Sucker 12 is arranged by the end of fixed part 122 on the outer wall of rack body 11.
Silicon stent provided by the utility model is axially inserted into patient throat along rack body, and it is narrow to be used to support throat
Section.After silicon stent merging, multiple suckers can be adsorbed on throat's inner wall so that silicon stent can be pasted closely with throat's inner wall
It closes, meanwhile, sucker structure increases the deformation nature of silicon stent radially, further avoids holder and is moved in patient throat
Position.
In the present embodiment, the length of 11 outer wall of the rack body in an axial direction is more than the length of inner wall in an axial direction so that branch
The both ends of frame ontology 11 form the end wall 111 with a fixed inclination.After the silicon stent merging patient throat of this programme, the tool
There is the skew wall 111 at oblique angle to facilitate fluid flow through, to effectively prevent throat that restenosis occurs.
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.
Claims (2)
1. a kind of silicon stent, which is characterized in that including rack body and multiple suckers, the rack body has tubulose knot
Structure, the multiple sucker is arranged on the rack body outer wall, and sucker disk is directed away from the direction of rack body.
2. silicon stent according to claim 1, which is characterized in that the length of the rack body outer wall in an axial direction is more than
The length of inner wall in an axial direction makes rack body both ends form the end wall with oblique angle.
