Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of five pawl auditory ossicle prosthesis of low stress.
Background technique
Due to disease, wound or congenital malformation, middle ear ossicles (are made of, nickname auditory ossicular chain, from outside to inside three ossiculums
Successively are as follows: malleus, incus, stapes, stapes is bent by stapes to be formed with stapes footplate, and the latter contacts with inner ear perilymph, is
Ear transmits these vibrations to the end-results of inner ear) usually it is damaged.Most common is that incus is impaired.If incus damage causes
It is discontinuous or fixed between eardrum and stapes footplate, then the vibration transmitted from eardrum just can not effectively be transferred to head of stapes,
So as to cause conductive hearing loss.After impaired incus is replaced by auditory ossicle prosthesis, the vibration transmitted from eardrum will be listened
Ossicle prosthesis is transferred to stapes head, and then partly or entirely compensates the impaired caused conductive hearing loss of incus.In addition, raw
The auditory ossicular chain of reason state has hammer anvil joint, incudostapedial joint, stapedial ligament, eardrum to link and malleus and incus with soft between malleus
Ligament, allow eardrum ear bones catenary system to buffer tympanum pressure change.The auditory ossicle prosthesis of this kind substitution incus is also known as
Make part artificial auditory ossicle or part auditory ossicle prosthesis.
Currently, part auditory ossicle prosthesis is generally made of top plate, connecting rod and fixture, thus instead of incus.It is existing listen it is small
Bone prosthese finds that the contact site Yu Erzhe top plate is contacted with eardrum when in use, when middle ear cavity pressure variation cause eardrum by
The shearing stress arrived and normal stress are excessive, and damage, perforation or even implant abjection can be caused to contact site eardrum；Top plate with
Connecting rod is fixed, and this hardwired mode can not buffer tympanum pressure change and cause eardrum in the method with artificial auditory ossicle contact site
It is dramatically increased to stress and shearing stress；In addition, stapes folder is generally four paws, seven pawls or eight pawls, existed when being connected with head of stapes
The problem of pine or tension.
Summary of the invention
The purpose of the present invention is to provide a kind of five pawl auditory ossicle prosthesis of low stress, which can be reduced and drum
Stress between film mitigates damage eardrum, and is easy to when middle ear air pressure change by angle automatic adjusument between top plate and connecting rod
Eardrum change in location is adapted to, to buffer middle ear pressure variation；By adjusting clip vane thickness, realization can be fixed on stapes
Head, but not lead to ischemic, decalcification, necrosis to stapes pressure is excessive；In addition facilitate and be connected with head of stapes, be elastic suitable.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of five pawl auditory ossicle prosthesis of low stress, including top plate, connecting rod and stapes press from both sides, and top plate is equipped with rib, the top plate bottom
Cavity equipped with invagination makes top plate form annular edge edge in cover shape and top plate periphery；Pass through cup-and-ball joint between top plate and connecting rod
It is connected；The stapes folder is five pawl structures.
Further, the rib of the top plate is S-shaped.
Further, buffer spring is equipped in the cup-and-ball joint.
Further, the top plate is rounded or oval.
Further, the cup-and-ball joint is located at top plate center or eccentric position.
The beneficial effects of the present invention are:
One, change top plate structure, make top plate when being in contact with eardrum, contact stress can be reduced, and avoid eardrum with
The acute angle generated when top plate relative tilt damage caused by eardrum, or even the tympanic membrane perforation or implant abjection；
Two, the rib in top plate is arranged to S-shaped, visual field when surgical procedure can be expanded, reduce the blind area of appearance, reduction is listened
Ossicle prosthesis quality；
Three, top plate and connecting rod are attached by cup-and-ball joint, the angle that can be adaptively adjusted between top plate and connecting rod,
Relative position between eardrum and top plate is caused to change suitable for the variation of different degrees of middle ear pressure；
Four, in cup-and-ball joint setting buffer spring can buffer portion middle ear air pressure change, reduce top plate to the pressure of eardrum, into
And reduce damage of the top plate to eardrum, reduce implant extrusion rate；
Five, stapes sandwiched is set to five pawl structures, being clipped in stapes elastic when connecting with stapes is suitable for that will not both damage because of tension
Hurt stapes, will not be fallen off due to excessively loose.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is face upwarding stereogram of the invention；
Fig. 3 is side view of the invention.
Specific embodiment
In conjunction with shown in Fig. 1~3, the present invention provides a kind of five pawl auditory ossicle prosthesis of low stress, including top plate 1, connecting rod 2 and stirrup
Bone folder 3；Top plate 1 is equipped with rib 4, and rib 4 is S-shaped；1 bottom of top plate is equipped with the cavity 5 of invagination, make top plate in cover shape and
Top plate periphery forms annular edge along 6；It is connected between top plate 1 and connecting rod 2 by cup-and-ball joint 7, preferably, cup-and-ball joint 7
It is interior to be equipped with buffer spring 8；Stapes folder 3 is five pawl structures, and five pawls are specially two pawl of rear, one pawl of front, each pawl in two sides, after
Two pawls of side make stapes folder match with the tendo musculi stapedius at head of stapes rear；Two pawls of bilateral tilt slightly inwards, are easy to be embedded in stirrup
In the gap between stapes bow below bone；One pawl in front, so that artificial auditory ossicle is unlikely to rearward to slide with head of stapes,
Play the role of fixed artificial auditory ossicle position；In addition, elasticity of the design by adjusting each pawl structure, takes out during being easy to use
Again it places without damaging stapes and stapedial ligament；Top plate 1 is rounded or oval；Cup-and-ball joint 7 is located in top plate 1
The heart can also be set to eccentric position.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form；Appoint
What those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the side of the disclosure above
Method and technology contents make many possible changes and modifications to technical solution of the present invention, or are revised as the equivalent reality of equivalent variations
Apply example.Therefore, anything that does not depart from the technical scheme of the invention according to the technical essence of the invention do above embodiments
Any simple modification, equivalent replacement, equivalence changes and modification, all of which are still within the scope of protection of the technical scheme of the invention.
