Description
Предметом изобретени вл етс пила дл образовани костного отверсти при операции дакриоцисториностомии , имеюща форму, обеспечивающую целость слизистой оболочки носа.The subject of the invention is a saw to form a bone hole in a dacryocystorhinostomy operation, having a shape that ensures the integrity of the nasal mucosa.
Известные инструменты дл выполнени упом нутой операции представл ют собой долота, продвигаемые ударами хирургического молотка , или фрезы, вращаемые, например , бормашиной. Эти инструменты не обеспечивают целости слизистой оболочки носа, что вл етс непременным условием успешности операции.Known tools for performing the above operation are chisels advanced by the blows of a surgical hammer, or milling cutters rotated, for example, by a drill. These tools do not ensure the integrity of the nasal mucosa, which is an indispensable condition for the success of the operation.
На чертеже изображен вид пилы сбоку.The drawing shows a side view of the saw.
Пила имеет форму части круга L на хорде которой нанесены зубцы 2.The saw has the shape of a part of a circle L on the chord of which teeth 2 are applied.
Эта форма обеспечивает целость слизистой оболочки носа, так как одновременно с продвижением вперед пила отслаивает слизистую оболочку от кости.This form ensures the integrity of the nasal mucosa, since, at the same time as moving forward, the saw detaches the mucosa from the bone.
Пила приводитс в движение шатунно-кривошипным механизмом с использованием электромотора и гибкого вала.The saw is driven by a connecting rod / crank mechanism using an electric motor and a flexible shaft.
