Injection device for a solid implant

摘要

The device has a plunger rod (36) sliding in a needle (4) of a main body. The device is arranged such that when it is pressed against tissues, the body slides from proximal to distal position for permitting penetration of the tissues by the needle. The rod remains fixed and maintains the implant at required depth in the tissues until the needle is removed when the body is returned from distal to proximal position. The main body slides along the length of a secondary body (26), where the secondary body is locked in an irreversible manner on the main body after utilization.
