Embodiment Construction

[0021] combine Figure 1~3 As shown, the present invention provides a tongue-shaped five-claw type auditory ossicle prosthesis, comprising an apical plate 1, a connecting rod 2 and a stapes clamp 3, the apical plate 1 is provided with ribs 7, and the ribs 7 are S-shaped; An S-shaped supporting tongue 4 is provided on the side of the top plate 1, and the supporting tongue 4 can cooperate with the malleus; image 3 As shown, the top plate 1 and the connecting rod 2 are connected through a ball joint 5, preferably, a buffer spring 6 is provided inside the ball joint 5; the stapes clamp 3 has a five-claw structure, and the five claws are specifically the rear Two claws, one claw on the front, one claw on each side, and the two claws on the back make the stapes clip coincide with the stapedius tendon behind the head of the stapes; the two claws on both sides are slightly inclined inward, which is easy to insert into the stapes under the head of the stapes In the gap between the bo...

Abstract

The invention discloses a tongue-shaped five-jaw type auditory ossicle prosthesis. The prosthesis comprises a top plate, a connecting rod and a stapes clamp; the side edge of the top plate is providedwith an S-shaped supporting tongue body, the supporting tongue body can be matched with the malleus, and the top plate is connected with the connecting rod through a ball-and-socket joint; the stapesclamp is of a five-jaw structure. The supporting tongue body is arranged to be matched with the malleus so that good support can be formed between the auditory ossicle prosthesis and the malleus, andthe stability is enhanced; the top plate is connected with the connecting rod through the ball-and-socket joint, the angle between the top plate and the connecting rod can be flexibly and conveniently adjusted, and requirements of different patients can be met; the stapes clamp is arranged to be of the five-jaw structure, so that the tightness of the stapes clamp is appropriate when connected with the stapes, and the stapes cannot be injured due to excessively high tightness and cannot fall off due to excessively low tightness.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tongue-shaped five-claw type auditory ossicle prosthesis. Background technique [0002] Due to disease, trauma or congenital deformity, the auditory ossicles of the middle ear (composed of three ossicles, also known as the ossicle chain, from outside to inside are: malleus, incus, stapes, stapes composed of stapes bow and stapes floor , the latter in contact with the inner ear perilymph, the last structure in the middle ear that transmits vibrations to the inner ear) is usually damaged. Most commonly, the incus is damaged. If the incus injury results in a discontinuity or fixation between the tympanic membrane and the stapes head, vibrations from the tympanic membrane cannot be effectively transmitted to the stapes head, resulting in conductive hearing loss. When the damaged incus is replaced by the auditory ossicle prosthesis, the vibration from the tympanic membrane...
