摘要：
The invention relates to an auxiliary tool used in medicine, particularly in ophthalmic surgery when performing vitreoretinal operations through accesses 23 and 25G. Target Utility Model - The design of the biodegradable plug material for the manufacture of more technological and allows without difficulty to install the plug into microaccesses formed in the sclera, providing reliable sealing vitreal cavity and, in a subsequent, rapid resorption. The technical result obtained by solving this problem - efficient, reliable sealing accesses vitreal cavity (resolve plug and the opening is delayed own tissue), decreased manufacturing complexity stub. Said technical result can be obtained if the plug for closing microaccesses in the vitreal cavity consisting of a cap and a base in the form of a cylindrical rod made of a biodegradable material which is a copolymer of lactic and glycolic acid, has a bonnet formed into a shape in which at least two opposite sides are straight and are arranged parallel to each other, and a cylindrical shaft portion disposed directly under the cap, a length of 0.5-0.6 mm diameters has p is less than the diameter of the rod of 0.1 mm at the distal end of the rod is chamfered at an angle of 45 °. In a particular embodiment, the characteristics of the plugs are the signs:- in the biomaterial stub share ratio of lactic and glycolic acid is 1: 9.- the diameter of the rod corresponds to the diameter of the cylindrical hole, into which installed plug,- a cylindrical rod having a length of at least 2.1 mm.Полезная модель относится к вспомогательным инструментам, применяемым в медицине, в частности в офтальмохирургии при выполнении витреоретинальных операций через доступы 23 и 25G. Задача полезной модели - разработать конструкцию заглушки из биодеградируемого материала более технологичную для изготовления и позволяющую без особых сложностей устанавливать заглушку в сформированный микродоступ в склере, обеспечивая надежную герметичность витреальной полос
