Description
Technical field
The present invention relates to the field of medical instrument technology, it is specifically a kind of can compensator or trimmer pressure auditory ossicle prosthesis.
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.Sometimes on malleus and/or incus and stapedial plate structure by
Damage, causes the vibration transmitted from eardrum just can not effectively be transferred to stapes footplate, so as to cause conductive hearing loss.When impaired
Ear bones replaced by auditory ossicle prosthesis after, the vibration transmitted from eardrum will be transferred to stapes footplate, and then portion by auditory ossicle prosthesis
Divide or all conductive hearing loss caused by damaged bone is listened in compensation.In addition, the auditory ossicular chain of physiological status has hammer anvil joint, anvil stirrup
Joint, stapedial ligament, eardrum link and the ligament of malleus and incus with soft between malleus, so that eardrum ear bones catenary system can be with
Buffer tympanum pressure change.This kind substitutes auditory ossicle prosthesis and is also referred to as whole artificial auditory ossicles or whole auditory ossicle prosthesis.
Currently, auditory ossicle prosthesis is generally made of top plate, connecting rod and pedestal, thus instead of structure on incus, stapedial plate and/
Or malleus.Existing auditory ossicle prosthesis finds that the contact site Yu Erzhe top plate is contacted with eardrum, when tympanum pressure when in use
The shearing stress and normal stress that power variation causes eardrum to be subject to are excessive, damage, perforation can be caused to contact site eardrum, or even plant
Enter body abjection；Top plate is fixed with connecting rod, this hardwired mode can not buffer tympanum pressure change cause eardrum with it is artificial
The normal stress of ear bones contact site is dramatically increased with shearing stress；In addition, pedestal is solid platform, on the one hand it is difficult to and stapes
Pedal plate is connected, and on the other hand is also not easy to heal.
Summary of the invention
The purpose of the present invention is to provide it is a kind of can compensator or trimmer pressure auditory ossicle prosthesis, which can reduce drum
The stress of film and artificial auditory ossicle contact portion avoids artificial auditory ossicle to the damage of eardrum, buffering middle ear pressure variation to greatest extent,
In addition facilitate and be connected with the pedal plate of stapes, grown into convenient for surrounding soft tissue, play the role of fixed artificial auditory ossicle, to realize best
Sound transmission effect.
The technical solution adopted by the present invention to solve the technical problems is:
It is a kind of can compensator or trimmer pressure auditory ossicle prosthesis, including top plate, connecting rod and pedestal, 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；The connecting rod includes from top to bottom successively to cut with scissors
Z-shaped upper connecting rod, middle connecting rod and lower link are connect and are formed, upper connecting rod top is connected with top plate by cup-and-ball joint, lower link bottom
End is connected with pedestal；The base bottom is equipped with groove, is additionally provided with one group of vertical through-hole on pedestal.
Further, the rib of the top plate is S-shaped.
Further, the groove of the pedestal is the triangular groove being axially arranged along pedestal.
Further, the pedestal two sides are respectively equipped with vertical triangular opening.
Further, the through-hole includes four, and four through-holes are in distributed rectangular in pedestal.
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, the structure for changing top plate, makes top plate when being in contact with eardrum, can reduce contact stress, and inclination is avoided to put
The acute angle generated when setting damage caused by eardrum；
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, can flexibly and easily adjust the angle between top plate and connecting rod
Degree is suitable for different sick Man's Demands；
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, for link design at three-stage structure, upper connecting rod and the hinge joint of middle connecting rod are axle center, enable middle connecting rod and lower link edge
Axis rotation realizes the fine tuning to height；
Six, the groove of base bottom and the triangular opening of pedestal two sides can be with the remaining lug boss split-phases in stapes footplate
It coincide, connect pedestal closely with stapes footplate, and grow into convenient for surrounding tissue, play fixed function；
Seven, the through-hole on pedestal can reduce the weight of pedestal, reduce total quality, and be also convenient for surrounding tissue and grow into, into
And fix auditory ossicle prosthesis.
