Description
Склерометры, содержащие руко тку с изогнутой по кривизне глазного блока рабочей частью, известны.Sclerometers containing a handle with a working part curved along the curvature of the eye block are known.
Предлагаемый склерометр отличаетс от известных тем, что он снабжен градуированной шкалой, вынесенной на руко тку, и двум жестко соединенными между собой подвижными муфтами, одна из которых располол ена на шкале руко тки, а втора , вл юш,а с указателем лимба, - на рабочем конце склерометра .The proposed sclerometer differs from the known ones in that it is equipped with a graduated scale, placed on the handle, and two rigidly interconnected movable couplings, one of which is located on the scale of the handle, and the second is connected. working end of sclerometer.
Такой склерометр удобен при отсчете замер емых рассто ний по склере.Such a sclerometer is convenient for measuring measured distances along the sclera.
На чертеже изображен предлагаемый склерометр в двух проекци х.The drawing shows the proposed sclerometer in two projections.
Склерометр содержит руко тку 1, рабоча часть 2 которой изогнута по кривизне глазного блока. На рабочей части расположена муфта 3, котора с помощью стальной нити 4 соединена с другой подвижной муфтой 5, перемещающейс вдоль шкалы 6, нанесенной на руко тку. Дл предотвращени отклонени муфты 5 от рабочей части 2 стальна The sclerometer contains a handle 1, the working part 2 of which is bent along the curvature of the eye block. On the working part there is a clutch 3, which with the help of a steel thread 4 is connected to another movable clutch 5, moving along the scale 6, applied to the handle. To prevent the coupling 5 from deviating from the working part 2, the steel
нитка 4 перемещаетс в желобке, имеющемс в передней части руко тки, и прижимаетс неподвижной муфтой 7.The thread 4 is moved in the groove, located in the front part of the handle, and pressed by the fixed sleeve 7.
Шкала 6 проградуирована в миллиметрах и ее нулевое положение соответствует положению муфты 3 на конце рабочей части 2. Муфта вл етс также указателем лимба. При замерах на склере передвигают муфту 5 и св занную с ней муфту 3. Отсчет замер емых рассто ний производ т по шкале 6.The scale 6 is graduated in millimeters and its zero position corresponds to the position of the coupling 3 at the end of the working part 2. The coupling is also a dial indicator. When measured on the sclera, the clutch 5 and the clutch 3 associated with it are moved. The measured distances are counted on a scale of 6.
Предмет изобретени Subject invention
Склерометр, содержащий руко тку с изогнутой по кривизне глазного блока рабочей частью, отличающийс тем, что, с целью удобства отсчета замер емых по склере рассто ний, градуированна щкала вынесена на руко тку, а дл производства замеров он снабжен двум жестко соединенными между собой подвижными муфтами, одна из которых расположена на шкале руко тки, а втора , вл юща с указателем лимба, - на рабочем конце склерометра.A sclerometer containing a handle with a working part curved along the curvature of the eye block, characterized in that, for the sake of convenience of reading the distances measured on the sclera, the graduated scale is retracted on the handle, and for production of measurements it is equipped with two rigidly coupled movable couplings one of which is located on the scale of the handle, and the second, which is with the dial indicator, on the working end of the sclerometer.
