  • Patent number: 11484403
    Abstract: An injector for introducing a capsular tension ring and intended for once-only use, and a method for manufacturing such an injector. The injector includes: a housing extending in longitudinal direction of the injector, and a throughfeed channel. A plunger is arranged movably in the channel and includes an engaging means for engaging the capsular tension ring, and further includes a guide element on a guide arm. A spring mechanism co-acts with the plunger and is configured to displace the plunger from a starting state, in which the engaging means engages the capsular tension ring, to an activating state in which the capsular tension ring is carried inward into the throughfeed channel. The housing has a guide with first and second channel parts, and a wall part for carrying the guide element from the first to the second channel part, and the first channel part is provided with a resistance threshold.
