Patent ID: 11504227

Abstract:
Provided is an injector assembly, comprising: —an injector, which has a plunger and a cannula and is designed to move an intraocular lens through the cannula by means of a translational motion of the plunger; —a magnetic coupling; and—a drive unit, which has a first coupling half of the magnetic coupling, a motor, which is designed to drive the first coupling half into a first rotational motion, and a housing, within which the first coupling half and the motor are encapsulated and which has an annular housing portion, which delimits a channel having a circular cross-section. The injector has a second coupling half of the magnetic coupling, and the injector and the second coupling half are arranged in the channel. The first coupling half is arranged around the annular housing portion and is thus designed to perform the first rotational motion around the annular housing portion and thus to drive the second coupling half into a second rotational motion by means of a magnetic field of the magnetic coupling, which magnetic field penetrates the annular housing portion. The injector is designed to convert the second rotational motion into the translational motion of the plunger.
