Description
Technical field
The utility model relates to technical field of medical instruments, a kind of rational in infrastructure, safe and reliable artificial tympanic ring.
Background technology
At present, for the patient of congenital atresia of external auditory meatus, need to carry out external auditory meatus and eardrum is rebuild, because without tympanic groove, tympanic ring structure, the eardrum of reconstruction cannot snap in tympanic groove, it is difficult to form normal morphology and angle, to solve this problem it is necessary to insert suitable tympanic ring substitute in surgical procedure.Existing tympanic ring shape and structure is notched circle, rely primarily on structure and produce deformation to provide support force, after inserting external auditory meatus, the pressure producing external auditory meatus is uneven, and patients experienced pain is obvious, and tradition tympanic ring tympanic ring narrower width can only support a part for duct in addition, patient is still had to have the situation that secondary is narrow after inserting tympanic ring, and tradition tympanic ring easily comes off, and after inserting tympanic ring, it is impossible to the problem of administration.
Summary of the invention
The utility model is for shortcoming and defect present in prior art, it is proposed that a kind of rational in infrastructure, convenient drug administration, it is possible to effectively reduction of patient is painful, and improves the artificial tympanic ring of result for the treatment of.
The utility model can be reached by following measures:
A kind of artificial tympanic ring, it is characterised in that being provided with the straight tube-like support using memorial alloy to make, the tube wall of described support is latticed, and the caliber of support is 6-8mm, a length of 12-15mm.
The a diameter of 0.2mm of grid wire in the utility model support.
Bracket outer described in the utility model can be with sheathed silicone tube, and wherein straight tube-like holder part stretches out silicone tube, to improve the operating reliability that support is inserted.
The external auditory meatus support that bracket outer described in the utility model can be made with sheathed NiTi plated film alloy, wherein straight tube-like holder part stretches out external auditory meatus support, to improve the operating reliability that support is inserted.
The utility model is in actual application, when using non-operative treatment to place, after removing external auditory meatus granulation, silicone tube is inserted external auditory meatus, after silicone tube expansion, make external auditory meatus diameter reach about 3mm, be then placed on diameter in frozen water and reduced by 6-8mm and be deformed into the support of about 2mm and put into rapidly narrow duct, complete to insert；When needs use operation method to place, form art by external auditory meatus, use intermediate split thickness skin graft skin-grafting, after being then placed in support or silicone tube being replaced by NiTi plated film alloy external auditory meatus support, Stent Implantation.
The utility model is compared with prior art, the circle of closing is used in structure, it is more uniformly stressed, patient tolerance improves, rely on the memory effect of material itself, under the effect of temperature, the softest support force is provided, entire length is 12-15 millimeter, effectively whole external auditory meatus is supported, the problem that external auditory meatus secondary is narrow can well be solved, in addition, it is divided into bare bracket and film coating bracket, bare bracket effectively solves tradition tympanic ring and easily comes off, and after inserting tympanic ring, the problem that cannot be administered, after tympanic ring is inserted, owing to outer surface is network structure, can well be combined with external auditory meatus after support, difficult drop-off, network structure will not stop the medicine therapeutic action to duct simultaneously；Film coating bracket can effectively solve the external auditory meatus of burnt degree without epithelial tissue, easily produces incarnant problem, after inserting film coating bracket, support with external auditory meatus laminating closely, the effective growth stopping external auditory meatus granulation, can quickly promote the healing of epithelial tissue.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is another embodiment structural representation of the present utility model.
Reference: support 1, silicone tube 2.
Detailed description of the invention:
Below in conjunction with the accompanying drawings the utility model is further described.
As shown in drawings, the utility model proposes a kind of artificial tympanic ring, it is characterised in that being provided with the straight tube-like support 1 using memorial alloy to make, the tube wall of described support 1 is latticed, and the caliber of support 1 is 6-8mm, a length of 12-15mm.
The a diameter of 0.2mm of grid wire in the utility model support 1.
Support 1 described in the utility model is outside can be with sheathed silicone tube 2, and wherein straight tube-like holder part stretches out silicone tube 2, to improve the operating reliability that support is inserted.
The outside external auditory meatus support can made with sheathed NiTi plated film alloy of support 1 described in the utility model, wherein straight tube-like holder part stretches out external auditory meatus support, to improve the operating reliability that support is inserted.
The utility model is in actual application, when using non-operative treatment to place, after removing external auditory meatus granulation, silicone tube 2 is inserted external auditory meatus, after silicone tube 2 expansion, make external auditory meatus diameter reach about 3mm, be then placed on diameter in frozen water and reduced by 6-8mm and be deformed into the support 1 of about 2mm and put into rapidly narrow duct, complete to insert；When needs use operation method to place, form art by external auditory meatus, use intermediate split thickness skin graft skin-grafting, after being then placed in support 1 or silicone tube 2 being replaced by NiTi plated film alloy external auditory meatus support, Stent Implantation 1.
The utility model is compared with prior art, the circle of closing is used in structure, it is more uniformly stressed, patient tolerance improves, rely on the memory effect of material itself, under the effect of temperature, the softest support force is provided, entire length is 12-15 millimeter, effectively whole external auditory meatus is supported, the problem that external auditory meatus secondary is narrow can well be solved, in addition, it is divided into bare bracket and film coating bracket, bare bracket effectively solves tradition tympanic ring and easily comes off, and after inserting tympanic ring, the problem that cannot be administered, after tympanic ring is inserted, owing to outer surface is network structure, can well be combined with external auditory meatus after support, difficult drop-off, network structure will not stop the medicine therapeutic action to duct simultaneously；Film coating bracket can effectively solve the external auditory meatus of burnt degree without epithelial tissue, easily produces incarnant problem, after inserting film coating bracket, support with external auditory meatus laminating closely, the effective growth stopping external auditory meatus granulation, can quickly promote the healing of epithelial tissue.
