Abstract
This utility model relates to a kind of alternative apparatus of human organ, provide a kind of artificial auditory ossicle of rotatable adjustable in length, comprise manubrium of malleus, stapes, rotating mechanism and listen basin, described stapes one end is connected with the described bottom surface of basin of listening, and the other end of stapes is connected with described manubrium of malleus by rotating mechanism.This utility model structure is simply light and handy, cheap, there is stable, not yielding getting loose and advantage that vibrating sensing is good, simultaneously, by rotating middle adapter, scalable manubrium of malleus and listen spacing between basin, and can random adjusting angle, thus the needs of different residual ear bones and stapes spacing can be met.
Description
Technical field
This utility model relates to a kind of alternative apparatus of human organ, is specifically related to the ear bones of the audition of the raising people of the implant into body tympanum indoor in ossicular chain operation.
Background technology
In modern ear operation, when treatment is listened osteonecrosis and caused audition disease, artificial auditory ossicle is usually adopted to recover audition.
In order to obtain effective therapeutic effect, manyly patent discloses a respective technology, artificial ceramic auditory ossicles disclosed in Chinese Patent Application No. 89215100.5, the artificial auditory ossicle that this patent provides is a kind of artificial ceramic auditory ossicles.Acoustic feature and clinical needs of foundation ossicular chain mechanical lever devise A, B, C, D, E, F type six kinds of ear bones, and various galianconism respectively long-armed with flat, cylindrical furcation, circular top is connected.According to the defect degree of patient's ossicular chain, a type is wherein selected to form the new ossicular chain playing microphone device.The technology that this patent provides, although easy to use, cheap, rustic, acoustic effect is poor;
For another example Chinese Patent Application No. 021149100 discloses a kind of artificial auditory ossicle made of marmem, comprise pallet, pallet connecting rod, memorial alloy intelligent fastener, pedal bone ZHUANLIAN extension bar, pedal bone pawl, it is characterized in that, adopt memorial alloy intelligent fastener, realize pallet and pedal the distance free adjustment between bone pawl.But because memorial alloy itself exists the factors of instability, and wherein containing harmful substance, price is higher, and structure is comparatively complicated simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of artificial auditory ossicle of rotatable adjustable in length, to overcome the defect that prior art exists, meets the needs of clinical practice.
The artificial auditory ossicle of rotatable adjustable in length described in the utility model, comprises manubrium of malleus, stapes, rotating mechanism and listens basin;
Described stapes one end is connected with the described bottom surface of basin of listening, and the other end of stapes is connected with described manubrium of malleus by rotating mechanism.
The beneficial effects of the utility model are:
Structure is simply light and handy, cheap, has stable, not yielding getting loose and advantage that vibrating sensing is good, meanwhile, by rotating middle adapter, scalable manubrium of malleus and listen spacing between basin, and can random adjusting angle, thus the needs of different residual ear bones and stapes spacing can be met.
Accompanying drawing explanation
Fig. 1 is the artificial auditory ossicle structural representation of stapes adjustable in length.
Fig. 2 is for listening basin top surface structure schematic diagram.
Detailed description of the invention
See Fig. 1 and Fig. 2, the artificial auditory ossicle of rotatable adjustable in length described in the utility model, comprises manubrium of malleus 1, stapes 2, rotating mechanism and listens basin 4;
Described stapes 2 one end is connected with the described bottom surface of basin 4 of listening, and the other end of stapes 2 is connected with described manubrium of malleus 1 by rotating mechanism;
Preferably, described stapes 2 is the cylinder of hollow;
Preferably, described rotating mechanism comprises middle adapter 301, ball 302 and connecting rod 303, one end of described middle adapter 301 is provided with groove, described ball 302 is arranged in described groove, described connecting rod 303 one end is connected with described ball 302, and the other end is connected with described manubrium of malleus 1;
Further, described connecting rod 303 other end is provided with and connects ball 3, and the end face of described manubrium of malleus 1 is provided with ball groove, and described connection ball 3 is embedded in described ball groove, and is fixed by clip 304;
Preferably, the inwall of described stapes 2 is provided with female thread, and the outer wall of described middle adapter 301 is provided with external screw thread, and stapes 2 is connected by screw thread with middle adapter 301;
Preferably, the described end face of basin 4 of listening is provided with grid stripes 401, so as to increasing the frictional force between ear bones and tympanum, plays the effect of prevention ear bones landing.
This utility model in use, by threaded adjusting manubrium of malleus and listen spacing between basin 4, is listened the angle of basin 4 arbitrarily can arrange according to the concrete condition of patient, is convenient to clinical practice.
