Abstract
An implant injection device includes an injection needle, a receiver housing receiving at least a first implant and a second implant, an injection mechanism, including a pushing rod arranged upstream from the implants and configured to push the implants through the injection needle between an initial position and a final position in which the implants are injected, a pushing device for pushing on the pushing rod, configured to exert a force to move the pushing rod from the initial position to the final position, an intermediate stop device holding the pushing rod in an intermediate position and opposing the force exerted by the pushing device when a stroke of the pushing rod reaches a predetermined distance corresponding to a length of injection of the first implant, and an actuator for actuation by a user, configured to release the pushing rod from the intermediate position to the final position.
