Description
Technical field
This utility model relates to a kind of medical surgical instrument, particularly a kind of apparatus for interventional therapy tracheo esophageal fistula.
Background technology
Tracheo esophageal fistula is due to congenital or posteriority reason, a kind of disease that the trachealgia caused as wound, the esophageal carcinoma etc. communicates, usually bring pulmonary complication that is serious, that be difficult to cure as aspiration pneumonitis etc., severe patient makes patient can not oral feeding, seriously reduces the quality of life of patient.Because trachea membranous part is elastic fiber, be difficult to healing once destroy, this is also be difficult to one of reason for the treatment of after tracheo esophageal fistula occurs.Because the relative motion between trachea and esophagus is comparatively large, the risk of the existing support landing of Stent of the prior art, also has support to involve the risk of damage, worn out trachealgia wall.Therefore, how to treat tracheo esophageal fistula, improve the quality of life of patient, become clinical a great problem.
Utility model content
The purpose of this utility model is to provide a kind of Novel air pipe esophageal fistula plugging device, novel, practical, effectively can control the generation of aspiration pneumonitis, and the risk effectively avoiding esophagus tracheal wall to be worn through.
This utility model is by the following technical solutions: a kind of Novel air pipe esophageal fistula plugging device, comprise shuttle shape trachea end vertical and positioned opposite and shuttle shape esophagus end, the boss-shaped that the two inner side is respectively equipped with the flexible material adapted with fistula mouth size is connected waist, and two are connected between waists and connected by spring.
Further, described two boss-shapeds connect waists and are located on the shuttle face, inner side of described shuttle shape trachea end and the shuttle face, inner side of shuttle shape esophagus end respectively between two parties, and the two ends of described spring respectively setting-in are fixed on two raised head faces connecting waists.
Further, the horizontal axis that on described shuttle shape trachea end and shuttle shape esophagus end, shuttle SCCP connection-oriented waist direction extends outside it coincides.
Further, described shuttle shape esophagus end is identical with the shape of shuttle shape trachea end and be arranged symmetrically with.
Further, the connection waist sizes on described shuttle shape esophagus end and shuttle shape trachea end is slightly less than the size of fistula mouth, can complete the shutoff of fistula mouth after release.
Further, described tracheo esophageal fistula plugging device is the self-inflated stopper that can stretch along its axis.
Further, described shuttle shape trachea end is connected waist with it, be connected waist with it be woven by memory alloy wire, then through single-piece mesh structure that vacuum heat is shaped to described shuttle shape esophagus end respectively.
Further, the shuttle face, outside of described shuttle shape trachea end and the shuttle face, outside of described shuttle shape esophagus end are provided with respectively between two parties the steel bushing for fixing netted plugging device two ends B alloy wire.
The beneficial effects of the utility model are: this utility model is by implanting trachea and esophagus Jian Lou road connecting place by tracheo esophageal fistula plugging device, hide fistula mouth, and the spring that plugging device central waist is designed to scalable change connects, when trachea and esophagus generation relative motion, can be out of shape by extension spring, make both sides stopper conform to esophagus and trachea does relative motion, thus effectively prevent the risk of the worn out esophagus of stifled apparatus or tracheal wall, safety is higher.Can effectively prevent food and secretions from polluting respiratory tract by fistula mouth after this Novel stopper inserts affected part, control the generation of aspiration pneumonitis, after this device places a period of time, fistula mouth can self-heal.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.
Below in conjunction with concrete accompanying drawing, realization of the present utility model is described in detail.
Specific embodiment of the utility model mode as shown in Figure 1 to 4, a kind of Novel air pipe esophageal fistula plugging device, comprise shuttle shape trachea end 1 vertical and positioned opposite and shuttle shape esophagus end 4, the boss-shaped that the two inner side is respectively equipped with the flexible material adapted with fistula mouth 6 size is connected waist 3, and two are connected between waists 3 and connected by spring 2.
In the present embodiment, two boss-shapeds connect waists 3 and are located on the shuttle face, inner side of shuttle shape trachea end 1 and the shuttle face, inner side of shuttle shape esophagus end 4 respectively between two parties, and the two ends of spring 2 respectively setting-in are fixed on two raised head faces connecting waists 3.The horizontal axis that on shuttle shape trachea end 1 and shuttle shape esophagus end 4, shuttle SCCP connection-oriented waist 3 direction extends outside it coincides.When there is relative motion between trachea and esophagus, extension spring 2 is out of shape, and does not destroy again the relative motion between trachea and esophagus while ensureing waist boss 3 shutoff fistula mouth 6.
Shuttle shape esophagus end 4 is identical with the shape of shuttle shape trachea end 1 and be arranged symmetrically with.Shuttle shape is the shuttle shape that small in ends, middle part is thick up and down.Shuttle shape esophagus end 4 is dimensioned slightly smaller than the size of fistula mouth 6 with the connection waist 3 on shuttle shape trachea end 1.The shutoff of fistula mouth can be completed after release.Tracheo esophageal fistula plugging device is the self-inflated stopper that can stretch along its axis.Shuttle shape trachea end 1 is connected waist 3 with it, described shuttle shape esophagus end 4 is connected waist 3 and is respectively and is woven by memory alloy wire, then through single-piece mesh structure that vacuum heat is shaped with it.Spring 2, for having the precision spring of certain elastic modelling quantity, has good fatigue life.
The shuttle face, outside of shuttle shape trachea end 1 and the shuttle face, outside of described shuttle shape esophagus end 4 are provided with respectively between two parties the steel bushing 5 for fixing netted plugging device two ends B alloy wire.
In the above embodiments, memory alloy wire can adopt nitinol alloy wire, also can adopt other metal alloy wires.Spring can adopt Nitinol to process, and also can adopt other metals.
Use procedure of the present utility model is as follows: can Automatic-expanding after being released by this tracheo esophageal fistula plugging device in the conduit of operation technique, and the shuttle shape trachea end 1 after release is placed in tracheal strips, the inner side of diagram tracheal wall 7.Shuttle shape esophagus end 4 is placed in esophagus, esophageal wall 8 inner side.Connect waist 3 and be placed in fistula mouth 6, namely spring 2 is through the connective tissue 9 between trachea and esophagus, thus makes whole device be stable in lesion.When trachea and esophagus generation relative motion, can be out of shape by extension spring 2, make the two ends of stopper conform to esophagus and trachea does relative motion, effectively avoid worn out esophagus or tracheal wall.After this tracheo esophageal fistula plugging device is placed on affected part a period of time, fistula mouth can self-heal.
Above tracheo esophageal fistula plugging device provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
