Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of turnable 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.If this damage causes auditory ossicular chain in eardrum and stapes
It is discontinuous or fixed between bottom plate, then the vibration transmitted from eardrum just can not effectively be transferred to stapes footplate, so as to cause biography
The property led hearing loss.After impaired phonophore is replaced by auditory ossicle prosthesis, the vibration transmitted from eardrum will be by auditory ossicle prosthesis
It is transferred to stapes footplate, and then partly or entirely makes up the impaired caused conductive hearing loss of phonophore.These phonophores
Some or all can use small prosthetic replacement.
Currently, auditory ossicle prosthesis is generally made of top plate, connecting rod and pedestal, to form instead of malleus, incus and stapes
Auditory ossicular chain.Existing auditory ossicle prosthesis finds that often stress is excessive when contacting with eardrum for top plate when in use, can give eardrum
It causes to damage；Top plate is mutually fixed with connecting rod causes scope of activities limited, and the unbearable middle ear cavity pressure of hardwired mode
Variation impact；In addition, pedestal is solid platform, on the one hand it is difficult to and the pedal plate of stapes is firm is connected, on the other hand around soft group
It knits and is also not easy to merge therewith.
Summary of the invention
The purpose of the present invention is to provide a kind of turnable auditory ossicle prosthesis of low stress, which can be reduced
Stress between eardrum avoids damage to eardrum, and scope of activities is conveniently adjusted greatly using angle, in addition facilitates the foot with stapes
Plate is connected, healing acceleration.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of turnable auditory ossicle prosthesis of low stress, including top plate, connecting rod and pedestal, top plate are equipped with rib；The top plate bottom
Portion is equipped with the cavity of invagination, and top plate is made to form annular edge edge in cover shape and top plate periphery；It is closed between top plate and connecting rod by ball-and-socket
Section is connected；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 causes relative position between eardrum and auditory ossicle prosthesis to change demand suitable for different tympanum pressure changes；
Four, setting buffer spring buffering air pressure and can also finely tune the stroke or height of auditory ossicle prosthesis in cup-and-ball joint；
Five, 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；
Six, 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.
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 bottom view of the invention；
