Механизм фиксации представлен цангой с одной зоной зажима и цилиндрической гайкой. Закрепление сменных насадок в механизме фиксации происходит следующим образом: сменная насадка вводится в цангу до контакта торцов выходного и магистрального световодов, после чего фиксируется путем закручивания на цанге цилиндрической гайки до упора. Оптическая связь между выходным и магистральным световодами реализована за счет непосредственного контакта торцов выходного и магистрального световодов. Known fiber-optic tool [1], containing a replaceable nozzle, including a smooth cylindrical flask and an output fiber, the locking mechanism, represented by a collet with one clamping area and a cylindrical nut, a standardized optical connector, the main fiber. The locking mechanism is represented by a collet with one clamping zone and a cylindrical nut. Fastening the interchangeable nozzles in the fixing mechanism is as follows: the interchangeable nozzle is inserted into the collet until the ends of the output and main optical fibers contact, and then it is fixed by tightening the cylindrical nut on the collet until it stops. Optical communication between the output and trunk fibers is realized through direct contact of the ends of the output and trunk fibers.

Заявленный инструмент используют следующим образом: The claimed tool is used as follows:
Заявленный инструмент переводят из транспортного положения в рабочее. Удаляют заглушки 19 и 20. Магистральный световод 1 , служащий для передачи лазерного излучения от блока генерации лазерного аппарата (на чертежах не показан), подключают к первому оптическому разъему 5. Одноразовый стерильный сменный наконечник 4, предназначенный для аппликации лазерного излучения на ткани и органы человека в пределах операционного поля, подсоединяют ко второму оптическому разъему 6 посредством втулки 10, выполненной в данном примере в виде стандартного коннектора типа Luer Conical Lock. Заявленный волоконно- оптический прибор готов к работе. The claimed tool is transferred from the transport position to the working one. Remove the plugs 19 and 20. The main fiber 1, which serves to transmit laser radiation from the laser unit generation unit (not shown in the drawings), is connected to the first optical connector 5. A disposable sterile interchangeable tip 4, designed to apply laser radiation to tissues and organs of a person within the surgical field, is connected to the second optical connector 6 via a sleeve 10, made in this example as a standard Luer Conical Lock type connector. The claimed fiber optic device is ready for use.
Для обеспечения доступа к органам и тканям при проведении вмешательств в заявленном волоконно-оптическом приборе используют стерильные одноразовые гибкие и жесткие сменные наконечники совместно. Одноразовые гибкие сменные наконечники выполнены согласно первому варианту реализации, как описано выше и показано на фиг. 2 и 4. В состав жестких сменных наконечников (по второму варианту реализации, как описано выше и показано на фиг.5) входят инструменты и приспособления медицинского назначения (иглы, канюли, катетеры либо иные инструменты, имеющие канал с разъемом типа Luer Conical Lock), необходимые в соответствии с методикой проведения манипуляции. To provide access to organs and tissues during interventions in the claimed fiber optic device, sterile disposable flexible and rigid replaceable tips are used together. Disposable flexible interchangeable tips are made according to the first embodiment, as described above and shown in FIG. 2 and 4. The composition of the hard interchangeable tips (according to the second embodiment, as described above and shown in Fig. 5) includes medical instruments and devices (needles, cannulas, catheters or other instruments having a channel with a Luer Conical Lock type connector) required in accordance with the methodology of the manipulation.
Корпус 2 предназначен для выполнения функции держателя ручного. В корпусе 2 отсутствуют полости и каналы, в которые при использовании по назначению могут попадать биологические жидкости, т.е. он соответствует требованию соблюдения условий стерильности. Case 2 is designed to perform the functions of a manual holder. In the case 2 there are no cavities and channels into which biological fluids, i.e. It complies with sterility requirements.
В лазерном медицинском аппарате (на чертежах не показан) излучение подается на выходной оптический разъем. Далее излучение попадает в последовательно подсоединенные к лазерному аппарату магистральный световод 1 , объектив 3 и сменный наконечник 4, и таким образом доставляется к операционному полю. In a laser medical device (not shown in the drawings), radiation is supplied to the output optical connector. Next, the radiation enters the trunk fiber 1, the lens 3 and the interchangeable tip 4, connected in series to the laser device, and thus is delivered to the surgical field.
Зона воздействия невидимого основного лазерного излучения на выходе сменного наконечника 4 может подсвечиваться видимым излучением пилотного лазера, входящего в состав источника лазерного излучения. Форма и размеры пятна пилотного лазера в зоне воздействия полностью соответствуют форме и размерам невидимого глазом основного лазерного излучения. Это позволяет контролировать расположение и размеры зоны воздействия основного лазерного излучения и избегать нежелательного повреждения окружающих тканей. The area of influence of the invisible main laser radiation at the output of the interchangeable tip 4 can be highlighted by the visible radiation of the pilot laser, which is part of the laser radiation source. The shape and size of the spot of the pilot laser in the exposure zone are fully consistent with the shape and size of the main invisible eye laser radiation. This allows you to control the location and size of the area affected by the main laser radiation and to avoid unwanted damage to surrounding tissues.
Дальнейшую работу прибором осуществляют в соответствии с методикой выполнения данного типа манипуляции. Further work with the device is carried out in accordance with the methodology for performing this type of manipulation.
После завершения манипуляции сменный наконечник и (при втором варианте) медицинский инструмент утилизируют. After the completion of the manipulation, the replaceable tip and (in the second embodiment) the medical instrument are disposed of.
Разработан, таким образом, простой волоконно-оптический инструмент и два варианта простого стандартизированного сменного наконечника для него, удобные с точки зрения соблюдения условий стерильности, и, за счет конструкции втулки сменного наконечника, совместимые со стандартным медицинским инструментом для подкожных, внутривенных или интракорпоральных манипуляций. Thus, a simple fiber-optic instrument and two versions of a simple standardized replaceable tip for it were developed, convenient from the point of view of observing sterility conditions, and, due to the design of the replaceable tip bush, compatible with a standard medical instrument for subcutaneous, intravenous or intracorporeal manipulations.
