ABSTRACT:
An implant syringe including a guide sleeve which has seated therein a syringe needle arrangement composed of a syringe needle, a needle holder, a grip member and a preparation receiving member. The syringe needle arrangement is blocked in an initial state by two spring arms that are cut out from the guide sleeve and obliquely project inwards such that they rest on a rear wall of the syringe needle arrangement. When the plunger of the implant syringe is pushed forwards to advance the preparation up to the head end of the syringe, a sleeve which is connected to the plunger abuts on the spring arms and bends them outwards, whereby the syringe needle arrangement can be retracted. The two operations are carried out without changing the position of the hand, thereby simplifying the handling of the implant syringe.
