Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of five claw auditory ossicle prosthesis of ligulate.
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 head of stapes, then the vibration transmitted from eardrum just can not effectively be transferred to head of stapes, from
And lead to conductive hearing loss.After impaired incus is replaced by auditory ossicle prosthesis, the vibration transmitted from eardrum will be listened small
Bone prosthese is transferred to stapes, and then partly or entirely compensates the impaired caused conductive hearing loss of incus.In addition, physiological status
Auditory ossicular chain have hammer anvil joint, incudostapedial joint, stapedial ligament, eardrum between malleus it is soft link and malleus and incus it is tough
Band allows eardrum ear bones catenary system to buffer tympanum pressure change.The auditory ossicle prosthesis of this kind substitution incus is also referred to as portion
Divide artificial auditory ossicle or part auditory ossicle prosthesis.
Currently, auditory ossicle prosthesis is generally made of top plate, connecting rod and stapes folder, to form auditory ossicular chain.It is existing listen it is small
Bone prosthese finds that the stability between malleus is poor when in use, and top plate is mutually fixed with connecting rod causes scope of activities limited, and
And the hardwired unbearable impact of mode；In addition, stapes folder is generally four paws, seven pawls or eight pawls, exist when being connected with stapes
Too loose or too tight problem.
Summary of the invention
The purpose of the present invention is to provide a kind of five claw auditory ossicle prosthesis of ligulate, the auditory ossicle prosthesis can with malleus it
Between formed and contact well, enhance the stability of artificial auditory ossicle, reduce artificial auditory ossicle and cause stress excessive contact eardrum part
And then eardrum is damaged, and scope of activities is conveniently adjusted greatly using angle, it is elastic when being in addition connected with stapes to be suitable for.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of five claw auditory ossicle prosthesis of ligulate, including top plate, connecting rod and stapes press from both sides, and top plate is equipped with rib；The top plate side
Equipped with S-shaped support tongue body, supports tongue body that can be formed with malleus and cooperate；Pass through cup-and-ball joint phase between top plate and connecting rod
Even；The stapes folder is five pawl structures.
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 is suitable for different sick Man's Demands；
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, 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 claw auditory ossicle prosthesis of ligulate, including top plate 1, connecting rod 2 and stirrup
Bone folder 3, top plate 1 is equipped with rib 7, and rib 7 is S-shaped；1 side of top plate is equipped with S-shaped support tongue body 4, supports 4 energy of tongue body
Enough and malleus, which is formed, to be cooperated；As shown in connection with fig. 3, it is connected between top plate 1 and connecting rod 2 by cup-and-ball joint 5, preferably, ball
Buffer spring 6 is equipped in nest joint 5；The stapes folder 3 is five pawl structures, and five pawls are specially two pawl of rear, one pawl of front, two sides
Each pawl in side, two pawls at rear make stapes folder match with the tendo musculi stapedius at head of stapes rear；Two pawls of bilateral tilt slightly inwards,
It is easy to be embedded in the gap between the stapes bow below head of stapes；One pawl in front, so that artificial auditory ossicle is unlikely to head of stapes
It rearward slides, plays the role of fixed artificial auditory ossicle position；In addition, elasticity of the design by adjusting each pawl structure, convenient for making
It is placed again with taking out in the process without damaging stapes and stapedial ligament.Top plate 1 is rounded or oval.Cup-and-ball joint 5
Positioned at 1 center of top plate, also can be set in 1 eccentric position of top plate.
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.
