Abstract
The utility model relates to an artificial titanium ear bone, consisting of a top plate, a post and a cup type hollow concave. The top plate is arranged above the post, and the cup type hollow concave is arranged below the post. The utility model is characterized in that the diameter of the top plate is 2.5mm and the thickness of the top plate is 0.1mm; the diameter of the post is 0.25mm to 0.28mm; the external height of the cup type hollow concave is 1.3mm, while the internal height of the cup type hollow concave is 1.2mm, and the external diameter of the cup type hollow concave is 1.3mm while the internal diameter of the cup type hollow concave is 1.2mm; and the depth of the cut of the cup type hollow concave is 0.8mm. The utility model has the advantages of higher mounting inosculation, greatly increasing the audition and good shape recovery.
Description
Technical field
This utility model relates to a kind of artificial 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, diameter 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 1.0mm, wide 0.8mm has audition after the titanium ear bones of this structure is installed and increases.
Summary of the invention
The purpose of this utility model be to provide a kind of install the goodness of fit higher, be more conducive to that audition improves and the artificial titanium ear bones of form after recovering.
For achieving the above object, a kind of artificial titanium ear bones of the present utility model by take over a business, cylinder, cup-shaped are hollow recessedly constitutes, the top of cylinder is for taking over a business, its below is that cup-shaped is hollow recessed, it is characterized in that: the diameter of taking over a business is that 2.5 millimeters, thickness are 0.1 millimeter; The diameter of cylinder is the 0.25-0.28 millimeter; The hollow recessed outer height of cup-shaped is that 1.3 millimeters, 1.2 millimeters of inner heights, external diameter are that 1.3 millimeters, internal diameter are 1.2 millimeters, and the degree of depth of its breach is 0.8 millimeter.
After adopting such structure, above parameters change meaning is its more approaching data of measuring for the human body stapes, design data manufacture of intraocular stapes articular fovea beguine is higher according to the artificial stirrup bone articular fovea goodness of fit of the preceding design data manufacturing of change in view of the above, therefore connect more firm, be difficult for displacement, so effective percentage is higher, bigger, the better effects if of audition increase rate.Artificial titanium ear bones takes over a business to change 60 degree angles with the cylinder junction into by original vertical an angle of 90 degrees and promptly becomes to have a down dip with vertical plane and 30 spend angles.Its objective is to take over a business after the operation and consistently with the tympanum plane be more conducive to than vertical angle that audition improves and the form recovery, go up item behind the normal tympanum of human body and limit the miter angle that has a down dip forward, having only artificial auditory ossicle to take over a business to be 30 degree has a down dip before the angles and adds that human body stapes downward-sloping naturally 10～20 spends angles, the two addition is the about miter angle of squint just, takes over a business this moment consistent with normal tympanum plane.What should propose is that the inclined plane that artificial titanium ear bones is taken over a business is the non-breach side of recess.Column diameter increases, and mainly is to be not easy to fracture in installation process, also can fully bear the mechanics load of acoustic vibration.
Description of drawings
Fig. 1 is the structural representation of the concrete a kind of embodiment of this utility model.
The specific embodiment
Of the present utility model a kind of titanium ear bones as shown in Figure 1, by take over a business 1, cylinder 2, cup-shaped hollow recessed 3 constitute, the top of cylinder 2 is for taking over a business 1, its below is that cup-shaped is hollow recessed 3, it is characterized in that: taking over a business 1 diameter and be 2.5 millimeters, thickness is 0.1 millimeter; The diameter of cylinder 2 is 0.27 millimeter; The outer height of cup-shaped hollow recessed 3 is that 1.3 millimeters, inner height are that 1.2 millimeters, external diameter are 1.3 millimeters, and internal diameter is 1.2 millimeters, and the degree of depth of its breach is 0.8 millimeter.This utility model is mainly based on 122 routine human body stapes top relevant structure specimen measurement results, and determines in conjunction with clinical practical experiences.
