На чертеже изображено устройство для измерения расстояния между объектом и дистальным концом зонда, общий вид.The drawing shows a device for measuring the distance between the object and the distal end of the probe, General view.

Устройство содержит упругий зонд 1, механизм его перемещения, выполненный в виде размещенных на конусе 2 ведущего валика 3 с профильной канавкой А для упругого зонда 1, шкалой 4 и фиксатором 5 показаний шкалы, рукояток 6 и 7, двух прижимных валиков 8, выполненных откидными·, кулачка 9 и приспособления 10 для возврата шкалы в первоначальное положение, выполненного в виде спиральной пружины.The device contains an elastic probe 1, the mechanism of its movement, made in the form of a drive roller 3 placed on a cone 2 with a profile groove A for an elastic probe 1, a scale 4 and a clamp 5 of the scale reading, the handles 6 and 7, two pressure rollers 8, made folding · , cam 9 and device 10 to return the scale to its original position, made in the form of a spiral spring.

Устройство работает следующим образом. Гибкий упругий зонд 1 проводят между профильной канавкой Д ведущего валика 3 и прижимными валиками 8, когда последние откинуты, путем поворота рукоят876102 ки 7 вместе с кулачком 9 по часовой стрелке. При повороте кулачка 9 по часовой стрелке фиксатор 5, прижимаясь к ведущему валику 3, фиксирует его. Одновременно при повороте кулачка 9 его 5 цилиндрическая поверхность откидывает прижимные валики 8, и гибкий упругий зонд 1 вручную приводят под ними через канал эндоскопа до момента, когда дистальная часть гибкого упругого зонда 1 10 начинает показываться на краю поля зрения эндоскопа. В этот момент путем поворота рукоятки 7 против часовой стрелки и одновременно с ней кулачка 9 опускаются прижимные валики 8, прижимая > ^ί5упругий зонд 1 к профильной канавке ведущего валика 3. После указанных операций устройство готово: к работе, и вращением ведущего валика 3 за рукоятку 6 против часовой стрелки упругий 20 зонд 1 подается вперед До соприкосновения .его дистального конца с объектом (не показан). Расстояние между объектом и дистальным концом эндоскопа указывается на шкале 4 против указателя (не обозначен). 25The device operates as follows. A flexible elastic probe 1 is carried out between the profile groove D of the drive roller 3 and the pressure rollers 8 when the latter are folded out by turning the handle 876102 ki 7 together with the cam 9 in a clockwise direction. When the cam 9 is rotated clockwise, the latch 5, pressing against the drive roller 3, fixes it. At the same time, when the cam 9 is rotated, its 5 cylindrical surface tilts the pressure rollers 8, and the flexible elastic probe 1 is manually brought under them through the endoscope channel until the distal part of the flexible elastic probe 1 10 begins to be shown at the edge of the endoscope's field of view. At this moment, by turning the handle 7 counterclockwise and simultaneously with the cam 9, the pressure rollers 8 are lowered, pressing>> ^{5 the} elastic probe 1 to the profile groove of the drive roller 3. After these operations, the device is ready: to work, and by rotating the drive roller 3 by the handle 6 counterclockwise, elastic 20 probe 1 moves forward until its distal end comes into contact with an object (not shown). The distance between the object and the distal end of the endoscope is indicated on a scale 4 against the pointer (not indicated). 25

После проведенных операций значение измеренного расстояния между объектом и дистальным концом эндоскопа фиксируется фиксатором 5, путем поворота рукоятки'7. При этом прижимные валики 9 от-30 кидываются, и упругий зонд 1 свободно удаляется. Во время перехода кулачка 9 из одного положения в другое при повороте рукоятки 7 против часовой стрелки с целью прижима упругого зонда 1 к ве- ₃₅дущему валику 3 фиксатором 5 освобож дается ведущий валик 3, и он под действием приспособления 10 возврата шкалы 4 возвращается в начальное положение.After the operations, the value of the measured distance between the object and the distal end of the endoscope is fixed by the latch 5, by turning the handle'7. In this case, the pressure rollers 9 from-30 are thrown, and the elastic probe 1 is freely removed. During the transition of the cam 9 from one position to another by rotating the handle 7 counterclockwise with the aim of pressing the elastic probe 1 to ₃₅ of Great previous of 3 roller retainer 5 is cleared is given the drive roller 3, and it is under the influence of the scale adaptations 10 4 return back to the start position.

Предлагаемое устройство позволяет сократить время измерения и повысить точность, что расширяет область и возможности его применения при постановке диагнозов различных заболеваний·внутренних полостей человека.The proposed device allows to reduce the measurement time and improve accuracy, which expands the scope and possibilities of its use in the diagnosis of various diseases · internal human cavities.

Claims

The invention relates to medical, in particular, to devices for diagnosing diseases of the internal cavities of the human body. A device for measuring the distance between the object and the distal end of the endoscope is known, which contains an elastic probe and a mechanism for moving it ulj. However, the known device does not provide the necessary accuracy of measurement, which limits its use, and also requires a long measurement time. The purpose of the invention is to reduce the measurement time and improve accuracy. This goal is achieved by the fact that in a device for measuring the distance between an object and the distal end of the aidoscope containing an elastic probe and its movement mechanism, the mechanism for moving the probe is made in the form of a drive roller with a profile groove for an elastic probe, with a scale and locking the readings, the handles, the handles, the two pressure rollers, the cam and the device for returning the scale to the original position. In this clamping rollers are folding. The drawing shows a device for measuring the distance between an object and the distal end of the probe, a general view. The device contains an elastic probe 1, a mechanism for its movement, made in the form of a drive roller 3 placed on a cone 2 with a profile groove A for an elastic probe 1, a tongue 4 and a retainer 5 readings, a handle 6 and 7, two pressure rollers 8, made folding -, the cam 9 and the fixture 10 for returning the tongues to their original position, made in the form of a spiral spring. The device works as follows. The flexible elastic probe 1 is guided between the profile groove A of the drive roller 3 and the pressure rollers 8, when the latter are folded back, by turning the arms 7 together with the cam 9 clockwise. When turning Kupachka 9 clockwise, the latch 5, pressing against the leading roller 3, fixes it. At the same time, when rotating the Kupacka 9, its cylindrical surface pushes out the clamping WAPS 8, and the flexible elastic probe 1 is manually brought under them Through the endoscope channel until the distal part of the flexible elastic probe 1 begins to show on the edge of the endoscope field of view. At this moment, the pressure rollers 8 are lowered counterclockwise and simultaneously with the cam 9, by pressing on Bopdi a, pressing the resilient probe 1 to the profile groove of the drive roller 3. After these operations, the device is ready: to work, and rotating the drive roller 3 by the handle In this case, the clock probe 1 resilient probe 1 is brought forward to the point of contact of its distal end by an object (not shown). The distance between the volume and the distal end of the endoscope is indicated on a scale of 4 against the pointer (not marked). 1 is freely removed. During the transition of the cam 9 from one position to another, when the handle 7 is turned anti-clockwise to clamp the elastic probe 1 to the drive roller 3 by the lock 5, the drive roller 3 is released, and it returns to its initial position under the action of the dial 10. The proposed device makes it possible to reduce the measurement time and improve accuracy, which expands the scope and possibilities of its use in making diagnoses of various diseases of the internal cavities of a person. 1. An apparatus for measuring the distance between an object and the distal end of an endoscope, comprising an elastic probe and a mechanism for its movement, which is necessary in order to reduce the measurement time and improve accuracy, the mechanism for moving the probe made in the form of a lead roller placed on the case with a profile .4 hollow for an elastic probe, a tongue and a gauge, a handle, two pressure rollers, a cam and a device for returning the scale to its original position.
