Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of ligulate 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.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 auditory ossicle prosthesis is found when in use when in use, the stabilization between malleus
Property is poor；Top plate is mutually fixed with connecting rod causes scope of activities limited, and the unbearable middle ear cavity pressure of hardwired mode becomes
Change 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, another aspect surrounding soft tissue
Also it is not easy to merge therewith.
Summary of the invention
The purpose of the present invention is to provide a kind of ligulate auditory ossicle prosthesis, which can form between malleus
It supports well, enhances stability, and scope of activities is conveniently adjusted greatly using angle, in addition facilitate and be connected with the pedal plate of stapes,
Healing acceleration.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of ligulate auditory ossicle prosthesis, including top plate, connecting rod and pedestal；The top plate side is equipped with S-shaped support tongue body, branch
It supports tongue body and can be formed with malleus and cooperated；It is connected between top plate and connecting rod by cup-and-ball joint；The base bottom is equipped with groove,
One group of vertical through-hole is additionally provided on pedestal.
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.
Further, the rib of the top plate is S-shaped.
The beneficial effects of the present invention are:
One, it is formed and is cooperated by setting support tongue body and malleus, enable to form good twelve Earthly Branches between auditory ossicle prosthesis and malleus
Support enhances stability；
Two, 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；
Three, 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；
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, 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 side view of the invention；
Fig. 4 is that pedestal of the present invention looks up amplification stereogram.
Specific embodiment
In conjunction with shown in Fig. 1~4, the present invention provides a kind of ligulate auditory ossicle prosthesis, including top plate 1, connecting rod 2 and pedestal 3, top
Disk 1 is equipped with rib 10, and rib 10 is S-shaped；1 side of top plate is equipped with S-shaped support tongue body 4, and support tongue body 4 can be with malleus
Form cooperation；It is connected between top plate 1 and connecting rod 2 by cup-and-ball joint 5, preferably, being equipped with buffer spring in cup-and-ball joint 5
6；3 bottom of pedestal is equipped with groove 7, and groove 7 is the triangular groove being axially arranged along pedestal；It is vertical that 3 two sides of pedestal further respectively have
