Изобретение предназначено для использования в хирургических, стоматологических и других инструментах. Сущность изобретения: использование в устройстве двух сопряженных торцевых поверхностей, расположенных под углом к продольной оси инструмента. Соединение скошенных поверхностей может быть различным, но при вращении одной части со скошенной поверхностью вокруг продольной оси происходит отклонение второй части от продольной оси. Максимум отклонения достигается при повороте первой части на 180o. Зависимость угла отклонения (максимального) от угла скоса выражается формулой: максимальный угол отклонения = 180o - 2. Описано два варианта конструкции устройства, различающихся по методу сопряжения скошенных торцевых поверхностей. В первом варианте обе скошенные поверхности соединены одна с другой внутренней осью, представляющей собой полый цилиндр, расположенный перпендикулярно к скошенной торцевой поверхности, находящийся в ее центре и прочно с ней соединенный. Во второй скошенной поверхности - соответствующее гнездо, в которое вставляется указанный цилиндр и в котором он может вращаться вокруг своей оси. Устройство легко дополняется механизмом, вращающим весь инструмент вокруг продольной оси. Во втором варианте обе скошенные поверхности соединены сквозной осью, крепящейся в боковых стенках инструмента. Эта ось расположена перпендикулярно к скошенным поверхностям и проходит через их центр. Внутренняя часть оси может быть прямой, слегка изогнутой или в виде кольца, пропускающего управляющий рабочими губками стержень или трос. Соединение скошенных торцевых поверхностей может быть осуществлено и другими методами - прочной пружиной, гибким (например, витым) цилиндром и т.д. С целью создания более пологой дуги поворота инструмента, более удобной в некоторых случаях и создающей лучшие условия для работы передающего усилия гибкого троса, могут быть использованы две и более пары сопряженных скошенных поверхностей. При этом могут быть использованы торцевые поверхности с малым отклонением от прямого угла.The invention is intended for use in surgical, dental and other instruments. The essence of the invention: the use of the device of two mated end surfaces located at an angle to the longitudinal axis of the tool. The connection of the beveled surfaces may be different, but when one part rotates with the beveled surface around the longitudinal axis, the second part deviates from the longitudinal axis. The maximum deviation is achieved when turning the first part 180 o . The dependence of the deflection angle (maximum) on the bevel angle is expressed by the formula: maximum deflection angle = 180 o - 2. Two versions of the device design are described, which differ in the method of conjugation of the beveled end surfaces. In the first embodiment, both beveled surfaces are connected to one another with an internal axis, which is a hollow cylinder, located perpendicular to the beveled end surface, located in its center and firmly connected to it. In the second beveled surface there is a corresponding nest into which the indicated cylinder is inserted and in which it can rotate around its axis. The device is easily complemented by a mechanism that rotates the entire instrument around the longitudinal axis. In the second variant, both beveled surfaces are connected by a through axis fastened in the side walls of the tool. This axis is perpendicular to the beveled surfaces and passes through their center. The inner part of the axis can be straight, slightly curved, or in the form of a ring, which transmits a rod or a cable that controls the working jaws. The connection of the beveled end surfaces can also be carried out by other methods - a strong spring, a flexible (for example, twisted) cylinder, etc. In order to create a flatter arc of tool rotation, which is more convenient in some cases and creates better conditions for the operation of the transmitting force of a flexible cable, two or more pairs of mated bevelled surfaces can be used. In this case, end surfaces with a small deviation from a right angle can be used.
