Изобретение относитс к медицине, а именно к отохирургии.The invention relates to medicine, namely to otosurgery.
Известен протез слуховых косточек, выполненный из пластического материала и содержащий ножку и головку 5Known prosthesis of the auditory ossicles, made of plastic material and containing the leg and head 5
Однако такой протез имеет ненадежную фиксацию в барабанной полости, так как протез жесткий и зафиксирован только один конец его, вследствие чего при грубом рубцевании, травмах, 10 движени х барабанной перепонки возможно смещение протеза.However, such a prosthesis has an unreliable fixation in the tympanic cavity, since the prosthesis is rigid and only one end is fixed, as a result of which, with rough scarring, injuries, and 10 movements of the eardrum, the prosthesis may shift.
Целью изобретени вл етс повышение надежности фиксации протеза в барабанной полости.15The aim of the invention is to increase the reliability of fixation of the prosthesis in the tympanic cavity.
Дл этого на ножке расположена втулка, соединенна с ножкой упругим элементом, причем на головке и втулке выполнены отверсти .For this, there is a sleeve on the leg, which is connected to the leg by an elastic element, with holes being made on the head and the sleeve.
Кроме того, по высоте ножки выпол-20 иены отверсти под крепление упругого элемента.In addition, the height of the leg wasp-20 yen holes for mounting the elastic element.
На фиг. 1 изображен протез слуховых косточек, общий вид; на фиг. 2 установка протеза в барабанной полос-25 ти при фиксированной пластинке стремени , на фиг. 3 - то же, при подвижной пластинке стремени.FIG. 1 shows the prosthesis of the auditory ossicles, a general view; in fig. 2, the installation of a prosthesis in the 25-tympan band with a fixed stirrup plate, in FIG. 3 - the same, with a movable plate of the stirrup.
Протез слуховых косточек содержит ножку 1, головку 2. На ножке 1 распо-30The prosthesis of the auditory ossicles contains leg 1, head 2. Leg 1 is located-30
ложена втулка 3, соединенна с ножкой упругим элементом 4. На головке 2 и втулке 3 выполнены отверсти 5 и 6. Упругий элемент размещен в одном из отверстий 7, выполненных по высоте цилиндрической ножки 1. Отверсти 7 располагают по высоте ножки дл облегчени моделировани протеза в момент его установки в барабанной полости в зависимости от глубины последней . Протез выполнен из пластмассы (тефлона, фторопласта, полихлорвинила ) .The sleeve 3 is connected to the leg by an elastic element 4. Holes 5 and 6 are made on the head 2 and the sleeve 3. The elastic element is placed in one of the holes 7 made along the height of the cylindrical leg 1. The holes 7 are positioned along the leg to facilitate the modeling of the prosthesis the time of its installation in the tympanic cavity, depending on the depth of the latter. The prosthesis is made of plastic (Teflon, PTFE, PVC).
В тех случа х,когда подножна пластинка стремени подвижна или ее удалось мобилизовать во врем операции , протез устанавливают таким образом , что ножка 1 и втулка 3, ввеценные в нишу овального окна, соприкасаютс с подножной пластинкой стремени . В отверсти 6 и 7 протеза врастает соответственно ткань барабанной перепонки и оболочки барабанной полости . В тех случа х, когда подножна пластинка стремени неподвижна, протез устанавливаетс так, что ножка 1 протеза углубл етс в преддверие лабиринта через перфорацию неподвижной пластинки стремени. Во всех случа х протез устанавливают таким образом, что голов « «In those cases when the foot plate of the stirrup is mobile or it was succeeded to mobilize it during the operation, the prosthesis is installed in such a way that the leg 1 and the sleeve 3, inserted into the niche of the oval window, are in contact with the foot plate of the stirrup. In the holes 6 and 7 of the prosthesis grows, respectively, the tissue of the eardrum and the shell of the tympanic cavity. In cases where the bottom plate of the staple is stationary, the prosthesis is set so that the stem 1 of the prosthesis goes deeper into the vestibule of the labyrinth through the perforations of the fixed plate of the staple. In all cases, the prosthesis is set in such a way that the heads ""
