Description

Изобретение относитс  к медицинской технике, в частности к протезам цепи слуховых косточек.The invention relates to medical technology, in particular to the prosthetic chain of the auditory ossicles.

Известен протез цепи слуховых косточек, имеющий пластинчатый саблевидный стержень с заостренным концом 1.A prosthetic chain of the auditory ossicles is known, having a lamellar saber rod with a pointed end 1.

Известный протез не обеспечивает надежность креплени  протеза в барабанной полости,The known prosthesis does not provide reliable attachment of the prosthesis in the tympanic cavity,

Целью изобретени   вл етс  повышение надежности креплени  протеза в барабанной полости.The aim of the invention is to increase the reliability of fixing the prosthesis in the tympanic cavity.

Поставленна  цель достигаетс  за счет того, что протез цепи слуховых косточек имеет пластинчатый саблевидный стержень с заостренным концом, установленную перпендикул рно стержню овальную пластину с прорезью, преимущественно из хр щевой ткани, другой коиец стержн  имеет форму ласточкиного хвоста и размещен в прорези пластины.This goal is achieved due to the fact that the prosthetic chain of the auditory ossicles has a lamellar saber rod with a pointed end, an oval plate perpendicular to the rod with a slot, mainly of cartilage, the other rod has the shape of a dovetail and is placed in the slot of the plate.

Такое выполнение протеза обеспечивает надежное крепление его в барабанной полости .This embodiment of the prosthesis provides reliable fastening it in the tympanic cavity.

На фиг. 1 изображен цротез цепи слуховых косточек, вид спереди; на фиг. 2 - то же, вид сверху.FIG. 1 shows the grotez of the chain of the auditory ossicles, front view; in fig. 2 - the same, top view.

Протез цепи слуховых косточек содержит пластинчатый саблевидный стержень 1 с заостренным концом 2, овальную пластину 3 с прорезью 4. Другой конец 5 стержн  1 имеет форму ласточкиного хвоста и размещен в прорези 4 пластины 3. Саблевидный конец 2 стержн  1 устанавливают наThe prosthetic chain of the auditory ossicles contains a lamellar saber rod 1 with a pointed end 2, an oval plate 3 with a slot 4. The other end 5 of the rod 1 has the shape of a dovetail and is placed in the slot 4 of the plate 3. The saber end 2 of the rod 1 is set to

5 передний отдел основани  стремени, второй конец 5 с овальной пластиной 3 подвод т под перепонку.5, the front portion of the stirrup base, the second end 5 with an oval plate 3 is guided under the membrane.

Протез обеспечивает за счет своей жесткости более эффективную передачу звуко1 10 вой волны к внутреннему уху.The prosthesis provides, due to its rigidity, a more efficient transmission of the sound wave to the inner ear.
