Abstract

The utility model discloses a full titanium auditory ossicle which comprises a podetium and a terminal disc arranged above the podetium. The full titanium auditory ossicle is characterized in that the lower end of the podetium is connected with an inflated free end; the podetium and the terminal disc are in connection of 50-70 degrees; the diameter of the terminal disc is 2-3 mm, and the thickness of the terminal disc is 0.50-0.2 mm, or the major diameter of the terminal disc is 2.5-3.5 mm, and the minor diameter of the terminal disc is 2-3 mm; the length of the podetium is 3-9 mm, and the diameter of the podetium is 0.2-0.4 mm; the podetium and the terminal disc are in eccentric connection. The full titanium auditory ossicle has the advantages that the requirements for the artificial auditory ossicle of different height and the requirements for different operation methods can be satisfied; the contacting area of the artificial auditory ossicle and a stapes soleplate is increased; the intensity of compression born by the unit area of the stapes soleplate is decreased; the danger of puncturing the stapes soleplate is prevented; the audition is well improved, and the shape recover is better.

Description

A kind of full titanium ear bones

Technical field

This utility model relates to a kind of titanium ear bones, specifically, relates to a kind of full titanium ear bones.

Background technology

At present, the top cover of the artificial titanium ear bones prosthesis on the 31st the 6th phase of volume of December in 1996 " Chinese hals,Nasen und Ohrenheilkunde magazine " is circular, and diameter is 3.0mm, thick 0.2mm, the center combines with post is vertical, and post directly is 0.1mm, the inverted wine cup shape of the likeness in form of lower end, external diameter 1.4mm; Interior is that cup-shaped is hollow recessed, internal diameter 1.3mm, and recessed dark 1.5mm has a symmetry incisura (breach) on the recess, dark 1.0nun, wide 0.8mm has audition after the titanium ear bones of said structure is installed and increases.

The utility model content

This utility model provides a kind of and has the installation of being fit to from the damaged patient who only has base plate even five base plates of body stapes superstructure, increase artificial auditory ossicle with from body stapes footplate contact area, reduce the stapes footplate unit are and bear the intensity of pressure, can cover the different crowd of required ear bones size and the difference of different modus operandis, audition improves better and form is recovered good full titanium ear bones.

For achieving the above object, this utility model has adopted following technical scheme:

A kind of full titanium ear bones, comprise taking over a business of cylinder and top thereof, it is characterized in that: the cylinder lower end is connected with expands free-end, and described diameter of taking over a business is that 2～3 millimeters and thickness are that 0.05～0.2 millimeter or the major diameter of taking over a business are that 2.5～3.5 millimeters and minor axis are 2～3 millimeters; The length of cylinder is 3～9 millimeters, and diameter is 0.2～0.4 millimeter.

It is eccentric the connection that described ellipse is taken over a business with cylinder, and the connection angle of taking over a business with cylinder is 50～70 °.

Be provided with the hole described on taking over a business.

The described free-end that expands is that circle is expanded free-end.

The utlity model has following effect:

1,,, this utility model only exist stapes footplate even not have the patient of base plate so being applicable to stapes superstructure disappearance because this utility model has adopted a kind of structure of full titanium ear bones;

2, for this utility model, the diameter of wherein taking over a business is that 2～3 millimeters and thickness are that 0.05～0.2 millimeter or the major diameter of taking over a business are that 2.5～3.5 millimeters and minor axis are 2～3 millimeters, the length of cylinder is 3～9 millimeters, column diameter is 0.2～0.4 millimeter, promptly taking over a business can be rounded or oval, ellipse takes over a business that to be the eccentric main purpose that is connected with main body be to allow more near the tympanum central part, is more conducive to the raising of sound conduction and audition;

3, take over a business diameter, take over a business choosing of thickness and column diameter scope their structures are each other mated more, for example take over a business enlarged-diameter, the diameter of its thickness and cylinder should increase thereupon, otherwise then reduces thereupon;

4, take over a business the angle that is connected with cylinder and cylinder length range and can satisfy between individuality and the race because of the artificial auditory ossicle of the same type of the volumetrical difference needs of tympanum different size, the different operation methods that different middle ear diseases are taked also need the artificial auditory ossicle of differing heights;

So the utlity model has cover different crowd and different modus operandis to the difference of artificial auditory ossicle requirement of the same type and increase artificial auditory ossicle with from body stapes footplate contact area, the pressure that minimizing stapes footplate unit are is born is worn out the danger of stapes footplate to prevent cylinder, thereby audition improves better and form is recovered.

Description of drawings

Below in conjunction with the drawings and specific embodiments this utility model is described in further detail.

Fig. 1 is a structure chart of the present utility model.

The specific embodiment

Fig. 1 is a structure chart of the present utility model.A kind of full titanium ear bones, what comprise cylinder 2 and top thereof takes over a business 1, takes over a business on 1 to be provided with hole 4 described.Wherein taking over a business 1 is eccentric connections with cylinder 2, take over a business 1 and the connection angle of cylinder 2 be 50～70 °, above-mentioned angle between the two is beneficial to and satisfies different human body and not agnate different requirements to this angle of artificial auditory ossicle.Cylinder 2 lower ends are connected with expands free-end 5, this expands free-end 5 is that circle is expanded free-end, using circle to expand free-end is beneficial to this utility model and stapes footplate contact area is suitably increased, reduce the pressure that the base plate unit are is born, prevent that cylinder from wearing out the danger of stapes footplate, also help vibration, be beneficial to the raising of audition stapes footplate.Take over a business 1 for oval, its major diameter is that 2.5～3.5 millimeters and minor axis are 2～3 millimeters, at this moment, taking over a business 1 is middle side 1/3 intersection of taking over a business 1 major diameter with the eccentric junction points that are connected of cylinder 2, is beneficial to 1 so more near tympanum central authorities, be more conducive to accept the vibration that sound wave causes tympanum, responsive more to sound, be more conducive to the raising of audition, certainly as required, it also can be circular taking over a business 1, and taking over a business 1 diameter this moment and be 2～3 millimeters and thickness is 0.05～0.2 millimeter.The length of cylinder 2 is 3～9 millimeters, diameter is 0.2～0.4 millimeter, the length of cylinder 2 wherein of the present utility model be 3～9 millimeters be for satisfy individual variation and race difference and satisfy to artificial auditory ossicle height different require and different modus operandi to the different requirements of artificial auditory ossicle height, and the diameter of cylinder 2 is 0.2～0.4 millimeter, is similarly 1 size and is complementary.

In a word,, should illustrate that obviously those skilled in the art can carry out various variations and remodeling though this utility model has exemplified above-mentioned preferred implementation.Therefore, unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included within the protection domain of the present utility model.
