Abstract
The invention discloses a method for manufacturing an external auditory canal model holder. The method comprises the following steps of: fixing an auditory canal model manufactured according to the external auditory canal of a patient in a utensil with a certain volume along the direction of a long axis, and pouring a solidifiable liquid material to the overall length of the model until solidifying; taking the auditory canal model out to obtain an auditory canal wall-shaped model; and finally, obtaining the external auditory canal model holder through pouring the solidifiable liquid material. The holder shape completely coincides with a reconstructed external auditory canal of the patient and has the effect of maintaining the shape so as to prevent restenosis and clausura, and meanwhile, the holder is convenient to wear and take out by the patient at any time.
Description
Technical field
The invention belongs to medical instruments field, in particular to a kind of method of making external auditory canal model holder with and use.
Background technology
At present, for the stricture of external auditory mea tus due to a variety of causes or locking patient, be expert at after reconstruction of external auditory canal, require to carry out for a long time packing of external auditory canal or support and keep its form, but because most patients can not adhere to for a long time, so the incidence rate of postoperative restenosis or locking is very high, and after external auditory meatus restenosis or locking, rebuild audition and can descend again, even drop to the front level of art, operation is counted out.Therefore, after reconstruction of external auditory canal, keeping of its form becomes a global problem, various external auditory meatus method for supporting and material arise at the historic moment, as silica gel tube, titanium net, alloy bracket, sliver filling, etc., but generally speaking, in case after using these materials and methods to insert the supporter of external auditory meatus, can not adjust bracing force and form, thereby easy compression skin of external auditory canal; The more important thing is, the difficulty of these operations is large, need to be completed by the doctor, and the patient need frequently go to hospital admission, and is not only uneconomical but also very time-consuming, so Most patients is difficult to adhere to for a long time, causes postoperative restenosis or locking, can't reach the purpose of healing.Inventor's utility model patent external auditory meatus dilator in the past can be adjusted support force and the form of external auditory meatus easily, reaches good support effect, and the patient can wear at home, and still, water filling needs other people to assist, and the patient can not complete voluntarily.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method of making external auditory canal model holder, modelling becomes the external auditory meatus support according to patient's external auditory meatus for it, this support form and patient reproduce external auditory meatus and fit like a glove, play the effect of keeping its form, thereby prevent restenosis and locking, the patient can wear voluntarily at any time easily or take out simultaneously.
According to an aspect of the present invention, the method for described manufacturing external auditory canal model holder comprises:
To be fixed on by long axis direction in the vessel of a constant volume according to the auditory meatus model that patient's external auditory meatus is made, cast solidifiable liquid material reaches total length until solidify;
Take out the auditory meatus model, obtain the auditory canal wall appearance model;
Directly to the liquid curable material of this auditory canal wall appearance model perfusion, to solidifying rear taking-up, obtain solid model support;
The core mill of the model support that this is solid is empty, forms the auditory meatus form, obtains external auditory canal model holder of the present invention.
According to another aspect of the present invention, the method for described manufacturing external auditory canal model holder comprises:
To be fixed on by long axis direction in the vessel of a constant volume according to the auditory meatus model that patient's external auditory meatus is made, cast solidifiable liquid material reaches total length until solidify;
Take out the auditory meatus model, obtain the auditory canal wall appearance model;
A hollow cylinder is placed in the center of the auditory canal wall appearance model that makes in the front step, to the cylindrical periphery liquid curable material of perfusion until solidify, take out, obtains external auditory canal model holder of the present invention.
The method according to this invention, described solidifiable liquid material comprise the material that liquid silica gel or acrylic (acrylic) or other are known in the art or following routine is used.
Another object of the present invention is to provide the external auditory canal model holder of making according to the inventive method.
The external auditory canal model holder that makes according to the inventive method is hollow structure, makes tympanum communicate with the external world, thereby neither affects audition, is beneficial to again drain, ventilation and observation.
Another object of the present invention is to provide the application of external auditory canal model holder after reconstruction of external auditory canal of making according to the inventive method.

The specific embodiment
In order to understand better essence of the present invention, the below describes technology contents of the present invention in detail with embodiment, but content of the present invention is not limited to this.
Fig. 1 shows human body ear solution cutaway view, wherein shows external auditory meatus 1, tympanum 2, tympanum 3, auditory ossicles 4, cochlea 5, vestibule 6 and pharyngotympanic tube 7.
As shown in Fig. 2-3, the patient after the reconstruction of external auditory canal of being expert at reproduces the interior filling liquid silica gel of auditory meatus 10 or other solidifiable liquid material 11, until be full of cavity of auricular concha, after solidifying, monoblock is taken out, and namely obtains the auditory meatus model 12 consistent with reproducing the auditory meatus form.
As required, can only make lateral segment part auditory meatus model, before filling liquid silica gel, first reach desired depth at auditory meatus deep filling sliver.
According to one embodiment of present invention, to be fixed in the vessel 13 of a constant volume by long axis direction (along the direction of external auditory meatus) according to the auditory meatus model 12 that patient's external auditory meatus is made, cast liquid silica gel (as shown by arrows) reaches total length until solidify, take out the auditory meatus model, stay the auditory canal wall form, directly pour into acrylic and obtain the solid model support to solidifying rear taking-up, the middle reduction of this model support is empty, form the auditory meatus form, obtain external auditory canal model holder 15.
According to another embodiment of the invention, to be fixed in the vessel 13 of a constant volume by long axis direction according to the auditory meatus model 12 that patient's external auditory meatus is made, cast liquid silica gel (as shown by arrows) reaches total length until solidify, take out the auditory meatus model, stay the auditory canal wall form, a hollow cylinder 14 is put in the auditory canal wall form center that makes in the front step, to cylindrical periphery perfusion acrylic until solidify, can directly be used as external auditory canal model holder 15 after taking-up.
Obviously, the liquid silica gel or acrylic that uses in embodiment, other material known in the art or following use also can be used as solidifiable liquid material of the present invention.
The external auditory canal model holder that makes according to the inventive method is hollow structure, makes tympanum communicate with the external world, thereby neither affects audition, is beneficial to again drain, ventilation and observation.
Above with the form of the specific embodiment, the present invention has been described exemplarily, replacement scheme, modification, modification, the improvement that generally use this area of knowing in the future but those skilled in the art can associate those well known in the prior art or present possibly can't predictions and the technical scheme that basically is equal to.Therefore, claims are intended to the technical scheme that contains these replacement schemes, modification, improvement and basically be equal to.
