Another part in multiple localization regions 102 intersects, and each lid of film 200 is located on a localization region 102.
Specifically, film 200 with a thickness of 0.1mm ~ 0.2mm.
Specifically, film 200 is selected from medical grade silicone film 200, medical grade e-PTFE film 200 and medical grade PU film
One of 200.
Above-mentioned silicon stent 10 at least has the advantages that
1) traditional silicon stent 10 is made of medical silica-gel material by mold extrusion forming, since silicon stent 10 is merging
Into air flue, and internal stent be cylindrical hollow configuration, ultrasonic wave be absorbed substantially after 10 tube wall of silicon stent or by
Outer wall surface scattering, is difficult to generate stronger echo, thus silicon stent 10 develop under ultrasound it is very fuzzy, along in tracheae
Development effect is more stronger under ultrasound for tissue (containing cartilaginous ring), is just more difficult to find out the profile of silicon stent 10 under ultrasound environments
And it measures and positions.Therefore, clinically doctor can only be checked by the way of Rigid bronchoscope observation under general anesthesia.
Above-mentioned silicon stent 10 includes rack body 100 and film 200, and rack body 100 is the tubulose knot of both ends open
Structure is equipped at intervals with multiple flanges 101 on the outer wall of the rack body 100, has localization region on the rack body 100
102, the rack body 100 offers multiple locating slots 103 in the localization region 102, and multiple locating slots 103 are
Even arrangement, and fill the full localization region 102, wherein the localization region 102 is located at the outer wall of the rack body 100
On, and between multiple flanges 101；Alternatively, the localization region 102 is located on the inner wall of the rack body 100；
The lid of film 200 is set on the localization region 102 of the rack body 100, and seals multiple locating slots 103, in institute
It states localization region 102 and forms multiple seal chambers.By the way that under the action of ultrasound, the gas in seal chamber can occur to vibrate and reflect
Strong ultrasonic signal to distinguish absorption and reflection of the airway tissue to ultrasonic wave, and is formed in localization region 102 multiple closed
Bubble structure to detect and be marked the profile of localization region 102, and then positions silicon stent 10.With biography
The silicon stent 10 of system is compared, and above-mentioned silicon stent 10 has the advantages that simple positioning method, hurtless measure, clinical application are convenient.
2) above-mentioned silicon stent 10 development effect under the action of ultrasound is very good, clear, and accurate positioning can be accurate
Judge the displacement situation of silicon stent 10；Simultaneously to patient safety, have no toxic side effect.
3) tube wall to rack body 100 of above-mentioned 10 selectivity of silicon stent carries out the improvement in structure, makes positioning area
Domain 102 has seal chamber, to generate stronger ultrasonic development effect；Meanwhile multiple seal chambers fill full localization region 102, lead to
The profile for judging localization region 102 is crossed, can clear, accurately silicon stent 10 be observed and be positioned.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
