Zusammenfassung: | FIELD: medicine. ^ SUBSTANCE: invention refers to surgical instruments for skin grafting. Device for skin tissue tensioning and obtaining free split skin transplants has the handle in the form of staple with braces at its ends and working section in the form of the spoke which is fixed onto the braces. The staple is made in the form of two detachable parts. The parts are connected by parts with flat side surfaces. The detachable parts have an option of mutual displacement and fixation of the screw clamp. Screw clamp includes a threaded rod and a nut. At least one part of the staple is equipped with at least one scale for determining the size of the skin flap. Threaded rod is installed in slots located in areas with flat lateral surfaces and has guiding planes for interaction with the slots. The size of the plane or the plane in the transverse direction relative to the longitudinal axis of the threaded rod is 0.25-2.25 of the slot width or the slot width. The size of the plane or the plane along the longitudinal axis of the threaded rod is not less than 0.6 of the total thickness of the sections with flat side surfaces or exceeds the total thickness of the sections with flat lateral surfaces of not less than 1/3 of the length of the nut threaded surface. ^ EFFECT: invention allows to adjust precisely the width and length autodermotransplant, provides conducting operations in ambustial patients of all ages (including children), provides a tangential necrectomy and tangential cleanse in ambustial patients; makes the fixation of skin grafts in the stretched state possible at the stage of sampling; reduces time of surgical treatment and anesthesia. ^ 3 cl, 3 dwg
Изобретение относится к хирургическим инструментам для пересадки кожи. Устройство для натяжения кожных тканей и получения свободных расщепленных кожных трансплантатов содержит ручку в виде скобы с фиксаторами на концах и рабочую часть в виде спицы, которая закреплена в фиксаторах. Скоба выполнена в виде двух разъемных частей. Части соединены участками с плоскими боковыми поверхностями. Разъемные части имеют возможность взаимного перемещения и фиксации винтовым прижимом. Винтовой прижим включает резьбовой стержень и гайку. Как минимум, одна часть скобы снабжена, как минимум, одной шкалой для определения размера кожного лоскута. Резьбовой стержень установлен в прорезях, которые расположены на участках с плоскими боковыми поверхностями и имеет направляющие плоскости для взаимодействия с прорезями. Размер п |
