Abstract
The utility model relates to an individualized external auditory canal stent which comprises a stent body and a holding handle. The holding handle is arranged outside the stent body, and a stent hole is formed inside the stent body. The individualized external auditory canal stent has the advantages that the stent hole enables the tympanic membrane to be communicated with the outside world, therefore, hearing cannot be influenced, and drainage, ventilation and observation are convenient; the holding handle enables a patient to wear and take off the stent conveniently, and the patient can manage the operations simply after simple guidance is carried out; the individualized external auditory canal stent is easy to clean and maintain, attractive and low in manufacturing cost, and has promotional value.
Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of individuation external auditory meatus support.
Background technology
At present, for stricture of external auditory mea tus or the locking patient due to a variety of causes, be expert at behind the reconstruction of external auditory canal, requirement is carried out packing of external auditory canal for a long time or is supported and keep its form, but owing to 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 the locking, rebuild audition and can descend again, even drop to the preceding level of art, operation is counted out.Therefore, behind the 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, the titanium net, alloy bracket, the sliver filling, the expansion sponge, rubber, but generally speaking, all there is congestion affects audition in these materials, win inconvenience, in case after using these materials and method to insert the supporter of external auditory meatus, with the incomplete driving fit of external auditory meatus, unbalance stress when wearing, can not adjust bracing force and form, thereby compressing damages skin of external auditory canal easily, long-term filling can cause infection, cause the part to fester, post-operative complication such as tissue necrosis, the difficulty of operation is big, need be finished by the doctor, and the patient need frequently go to hospital admission, not only uneconomical but also very time-consuming, therefore Most patients is difficult to adhere to for a long time, causes postoperative restenosis or locking, can't reach the purpose of healing.
The utility model content
The purpose of this utility model is to propose individuation external auditory meatus support, described individuation external auditory meatus support is the therapy equipment behind patient's canaloplasty of external auditory meatus, external auditory meatus is supported in filling, prevention of postoperative stricture of external auditory mea tus or locking, the medical devices that in artificial external auditory meatus tract and with external auditory meatus, directly contacts.
Individuation external auditory meatus support described in the utility model comprises rack body and holds handle, and the described handle of holding is located at the rack body outside, and described rack body inside is provided with a bracket holes.
Be preferably, described rack body is cylindrical shape, adopts the flexible material manufacturing.
Be preferably, the length of described rack body is the degree of depth of external auditory meatus.
Be preferably, the diameter of described bracket holes is 2mm, and its length connects the entire bracket body.
Be preferably, the described handle of holding is oblique overhanging elastomer.
Compared with prior art, the superior effect of individuation external auditory meatus support described in the utility model is: described bracket holes makes tympanum communicate with the external world, thereby neither influences audition, is beneficial to drain, ventilation and observation again; The described handle of holding is beneficial to the patient and wears easily and win, and only need simply instruct the patient to get final product described individuation external auditory meatus support easy cleaning, maintenance, attractive in appearance, low cost of manufacture, tool promotional value.
Description of drawings
Fig. 1 is individuation external auditory meatus supporting structure sketch map described in the utility model.
Description of reference numerals is as follows:
The 1-rack body, the 2-bracket holes, 3-holds handle.
The specific embodiment
Below in conjunction with accompanying drawing this utility model specific embodiment is described in further detail.As shown in Figure 1, described individuation external auditory meatus support comprises rack body 1 and holds handle 3 that the described handle 3 of holding is located at rack body 1 outside, and described rack body 1 inside is provided with a bracket holes 2.
Described rack body 1 is cylindrical shape, the use flexible material is made, the inwall of described rack body 1 outer surface and external auditory meatus is fitted fully, the length of described rack body 1 is the degree of depth of external auditory meatus, rack body 1 is inserted external auditory meatus, can play the effect that filling is supported, avoid the problem of postoperative stricture of external auditory mea tus, the diameter of described bracket holes 2 is 2mm, its length connects entire bracket body 1, ventilate, do not hinder the conduction of sound, describedly hold the resin material that handle 3 is transparent configurations, body reaction is slight when wearing, long-term wearing comfort is good, and described rack body 1 is complete when in place, holds handle 3 and is positioned at cavity of auricular concha, rack body 1 is won conveniently, and the described handle 3 of holding is oblique overhanging, elongated elastomer, thus external force conducts to middle ear after the reconstruction, injury middle ear rigidly when avoiding unexpected touching.In previous tretament, be that 40 routine patients have made individuation external auditory meatus support, and followed up a case by regular visits to and follow the tracks of 1-6, adhere to that all the time the patient who wears reaches 97.5%, after long-term treatment, all do not have the stricture of external auditory mea tus problem and take place, do not have other complication problems yet and take place.Individuation external auditory meatus support described in the utility model is easy and simple to handle, easy cleaning, maintenance, attractive in appearance, low cost of manufacture, tool promotional value.
This utility model is not limited to above-mentioned embodiment, and under the situation that does not deviate from flesh and blood of the present utility model, any distortion that it may occur to persons skilled in the art that, improvement, replacement all fall into scope of the present utility model.
