Abstract
The present invention discloses a kind of length-adjustable incus replacement prosthesis, pressed from both sides including stapes, stapes ogival sections is equipped with horizontal connecting rod, connecting rod is axially spaced be equipped with one group for and the lantern ring that matches of incus, connecting rod is also equipped at intervals with one group of annular groove along axial direction, and annular groove is staggered with lantern ring；The stapes folder is five pawl structures；By being arranged annular groove, connecting rod can be broken disconnected from the position of annular groove, therefore this auditory ossicle prosthesis can change the length of connecting rod when being connected with incus, require so that the position of lantern ring be made to can adapt to the different of various patients；It is connected with stapes in addition, the stapes folder of five pawl structures is more convenient, is elastic suitable.
Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of length-adjustable incus replacement 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, incus are divided into body portion, long foot and short foot three parts.Stapes is by stapes bow and stapes footplate group
At the latter contacts with inner ear perilymph, is the end-results that middle ear transmit these vibrations to inner ear) usually it is damaged.At most
What is seen is that long limb of incus is impaired.If incus damage leads to the discontinuous or fixation between eardrum and stapes footplate, from drum
The vibration that film transmits just can not effectively be transferred to head of stapes, so as to cause conductive hearing loss.When impaired incus listened it is small
After bone prosthetic replacement, the vibration transmitted from eardrum will be transferred to stapes head by auditory ossicle prosthesis, and then partly or entirely compensate
Conductive hearing loss caused by incus is impaired.The auditory ossicle prosthesis of this kind substitution incus is also referred to as part artificial auditory ossicle or part
Auditory ossicle prosthesis.
The case where for phonophore long limb of incus partial destruction, the general composite construction formed using stapes folder with lantern ring come
Auditory ossicular chain is formed, stapes folder is connected with stapes, and lantern ring is used for and the socket of remaining incus；Due to the feelings of each patient's incus damage
Condition is different, therefore the length for remaining incus is different, but at present the length of auditory ossicle prosthesis lantern ring be it is fixed, there are too long or
Too short situation, the too long position that will lead to socket is improper, it is too short if will lead to and can not be socketed at all again, do not adapt to each
The different demand of kind case；In addition, stapes folder is essentially four paws, seven pawls or eight pawls, there are too loose or too tight when being connected with stapes
The case where.
Summary of the invention
The purpose of the present invention is to provide a kind of length-adjustable incus replacement prosthesis, the anvil prosthese with the remaining long foot phase of incus
It can be cut according to incus nubbin length to suitable length when connection, adapt to the different of various cases and require；And stapes sandwiched
Five pawl structures are calculated as, it is convenient to be connected with stapes, is elastic suitable.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of length-adjustable incus replacement prosthesis, including stapes folder, the stapes ogival sections are equipped with horizontal connecting rod, and connecting rod is along axial
Be equipped at intervals with one group for and the lantern ring that matches of incus, connecting rod is also equipped at intervals with one group of annular groove along axial direction, annular groove with cover
Ring is staggered.
Further, the lantern ring is opening or silent.
Further, the stapes folder is five pawl structures.
The invention has the advantages that by setting annular groove, connecting rod can be broken disconnected from the position of annular groove, therefore this is listened
Ossicle prosthesis can change the length of connecting rod when being connected with incus, so that the position of lantern ring be made to can adapt to various patients'
Difference requires；It is connected with stapes in addition, the stapes folder of five pawl structures is more convenient, is elastic suitable.
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 top view of the invention；
Fig. 3 is stereoscopic schematic diagram of the invention；
Fig. 4 is face upwarding stereogram of the invention.
Specific embodiment
In conjunction with shown in Fig. 1~4, the present invention provides a kind of length-adjustable incus replacement prosthesis, including stapes folder 1, the stapes
1 top of folder is equipped with horizontal connecting rod 2, connecting rod 2 is axially spaced be equipped with one group for and the lantern ring 3 that matches of incus, 2 edge of connecting rod
Axial to be also equipped at intervals with one group of annular groove 4, annular groove 4 is staggered with lantern ring 3；Lantern ring 3 can be opening, or close
Mouthful.Stapes folder 1 is five pawl structures, and five pawls are specially two pawl of rear, one pawl of front, each pawl in two sides, and two pawls at rear make stirrup
Bone folder matches with the tendo musculi stapedius at head of stapes rear；Two pawls of bilateral tilt slightly inwards, are easy to be embedded in the stirrup below head of stapes
In gap between bone bow；One pawl in front plays fixed artificial so that artificial auditory ossicle is unlikely to rearward to slide with head of stapes
The effect of ear bones position；In addition, elasticity of the design by adjusting each pawl structure, taken out during being easy to use place again without
Damage stapes and stapedial ligament.
When in use, stapes folder 1 is connected with stapes, and the stapes due to using five pawl structures presss from both sides, when being connected with stapes
It can accomplish that elastic is suitable for that both will not damage stapes because of tension, too loose will not deviate from from stapes.Lantern ring 3 is socketed on patient
On remaining incus, since the length of each patient's residue incus is different, it can according to need, broken from the position of respective annular slot
Cracking connecting rod requires so that the position of lantern ring be made to can adapt to the different of various patients.
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.
