摘要： The object of the invention is an injector (1) for implantation of an intraocular lens, having a base body (10) and an elongated actuation element (11), which projects at least partly into a rear section of the base body (10) and which is movably guided in an actuation axis (12), and wherein a movement of the actuation element (11) into the base body (10) can be generated selectively by means of a push actuation (P) along the actuation axis (12) or by means of a screw actuation (S) about the actuation axis (12), and wherein the actuation element (11) features an external thread (13) at least on one section, wherein at least one spring arm (14) is arranged at the base body (10), wherein the spring arm (14) has a thread engagement structure (15) on an inner surface facing the external thread (13), and wherein a switch element (16), which can be rotated about the actuation axis (12), is arranged on the base body (10) and has a passage, through which the actuation element (11) extends, wherein the passage features at least one inner surface (17) having an inner radius (Ri) varying at least in sections in a circumferential direction, and wherein an outer surface (18) of the spring arm (14) is in contact with the inner surface (17) of the switch element (16), so that upon a rotation of the switch element (16) about the actuation axis (12), due to the varying inner radius (Ri) at the circumferential position of the spring arm (14), an elastic deformation of the spring arm (14) towards the actuation axis (12) and away from the actuation axis (12) can be generated, whereby the thread engagement structure (15) can be selectively engaged or disengaged with the external thread (13).

摘要： An intraocular lens implantation injector has a base body and elongated actuation element projecting into a base body rear section, movably guided along an actuation axis. Actuation element movement is generated selectively by axial push actuation or screw actuation about the axis. The actuation element features an external thread at least on one section. A switch element arranged to the base body is rotatable about or displaceable along the axis. The switch element features a spring arm, having an inner surface thread engagement structure facing the external thread. The base body inner surface forms an operative contact with a spring arm outer surface. The inner and/or outer surface is angularly inclined to the axis, or the inner surface features an inner radius varying circumferentially at least in sections about the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, for selective thread engagement structure engagement.

摘要： An intraocular lens implantation injector has a base body and an elongated actuation element projecting into a base body rear section and movably guided along an actuation axis. Actuation element movement is generated selectively by axial push actuation or by a screw actuation about the axis. The actuation element features an external thread at least on one section. At least one spring arm arranged at the base body has an inner surface thread engagement structure facing the external thread. A switch element, interacting with the spring arm, is rotatably or displaceably arranged on the base body. The switch element interacts with the spring arm via an operative contact. At least one switch element inner surface and/or spring arm outer surface involved in the operative contact is angularly inclined to the axis. Switch element rotation/displacement generates spring arm elastic deformation towards/away from the axis, thereby engaging/disengaging the thread engagement structure.
