Description

Auditory ossicle prosthesis with high reliability

Technical Field

The utility model relates to the technical field of medical equipment, specifically a high reliability listen ossicle prosthesis.

Background

The ossicles of the middle ear (consisting of three ossicles, called auditory ossicle chain, in sequence from the outside inwards: malleus, incus, stapes, the stapes consisting of the stapes arch and the stapes footplate, the latter being in contact with the perilymph fluid of the inner ear, the last structure of the middle ear that transmits vibrations to the inner ear) are often damaged by disease, trauma or congenital deformities. If such damage results in discontinuity or fixation of the ossicular chain between the tympanic membrane and the stapes footplate, vibrations transmitted from the tympanic membrane are not efficiently transmitted to the stapes footplate, resulting in conductive hearing loss. When the damaged ossicle is replaced by the ossicle prosthesis, the vibration from the tympanic membrane is transmitted to the stapes footplate by the ossicle prosthesis, and the conductive hearing loss caused by the ossicle damage is partially or completely compensated. Some or all of these ossicles may be replaced with a small prosthesis.

Currently, auditory ossicle prostheses are generally composed of a head plate, a linkage and a base, constituting the ossicular chain replacing the malleus, incus and stapes. The base of the existing ossicle prosthesis is generally a cylinder, so that the operation is not easy during the operation, and the arc surface is easy to slide in the ear; in addition, the ribs on the top plate are generally criss-crossed, which can enlarge the surgical field of view, but also reduce the strength.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high reliability listen ossicle prosthesis, should listen ossicle prosthesis and guarantee intensity, the non-deformable of paring disk under the prerequisite of ensureing the operation field of vision, and improve the maneuverability when performing the operation.

The utility model provides a technical scheme that its technical problem adopted is:

a high-reliability ossicle prosthesis comprises a top disc, a connecting rod and a base, wherein the top disc is provided with ribs; the top disc is divided into three sectors by the ribs; the base is in a trapezoidal table shape.

The utility model has the advantages that the ribs are designed into Y shape, on one hand, the operation visual field can be ensured, and on the other hand, the triangular stable support is formed, thereby ensuring the strength of the top plate and not being easy to deform; the trapezoidal table-shaped base is convenient for clamping operation during operation, and is not easy to slide after being installed in the ear, so that the use after operation is ensured.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a front view of the present invention;

fig. 3 is a plan view of the present invention.

Detailed Description

With reference to fig. 1 to 3, the present invention provides a highly reliable ossicle prosthesis, which includes a top plate 1, a connecting rod 2 and a base 3, wherein the top plate 1 is provided with ribs 4; the rib 4 is Y-shaped, the top disc is uniformly divided into three sectors by the rib 4, and the central point of the rib 4 is a circular disc; the base 3 is trapezoidal table form, and two faces are vertical setting, and two faces are arc inclined planes about the trapezoidal table.

The ribs are designed into a Y shape, so that the operation visual field can be ensured on one hand, and a triangular stable support is formed on the other hand, so that the strength of the top plate is ensured, and the top plate is not easy to deform; the trapezoidal table-shaped base is convenient for clamping operation during operation, and is not easy to slide after being installed in the ear, so that the use after operation is ensured.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.

Claims (1)

1. A high-reliability ossicle prosthesis comprises a top disc, a connecting rod and a base, wherein the top disc is provided with ribs, and the ossicle prosthesis is characterized in that the ribs are Y-shaped and divide the top disc into three sectors; the base is in a trapezoidal table shape.
