摘要：
The invention relates to microsurgical instruments used in ophthalmic surgery on the cornea during operations, namely to tools for raising corneal flap formed using a femtosecond laser.Target Utility Model - improve spatula design to improve efficiency and atraumatic its operation, both at the initial stage, using for the separation of the flap in the area of the periphery of one working end and the next stage - during a complete separation of the flap from the stromal bed using a second arcuate working end.The technical result - reducing intra-operative complications at the stage of raising povehnostnogo corneal flap formed by a femtosecond keratome, ease of operation.Said technical result can be obtained if a spatula bilaterally to lift the corneal flap is formed using the femtosecond laser, comprising a handle and a distal working portion of the one and the other side, the one working part is a cutter device by which the separated flap edge stroma, and the other is formed as a spatula, a curved arc, through which separated and lift flap, each working portion is located at an obtuse angle to the handle, the cutting Device ystvo embodied as a plate in the form of a trapezoid where cutting is greater base of the trapezoid formed as a shallow arc which is the distal part of the device and has a two-way sharpening and angles formed smaller base the trapezoid and its lateral sides are rounded, and the thickness of the plate is 0.1 mm and the edge angle of 35 °, and the second working part, designed as a spatula, curved in an arc in cross section has a rounded rectangle, a thickness of 0.2 mm and the curvature radius of the arc is 17 mm .Полезная модель относится к микрохирургическим инструментам, используемым в офтальмохирургии при операциях на роговице, а именно к инструментам для поднятия роговичного лоскута, сформированного с помощью фемтосекундного лазера.Задача полезной модели - усовершенствовать конструкцию шпателя с целью повышения эффективности и атравматично
