1. A safety housing based implant/medicament injecting system comprising:
a housing comprising an outer housing and an inner housing;
a needle assembly having a cannula at a front end of the needle assembly and a subsequent needle holder that is in fluid communicable connection with the cannula, the needle holder being fully accommodated within the inner housing and the outer housing and supported with a spring positioned between an outer housing top and the front end of the needle assembly;
a plunger rod configured for:
an initial forward motion of the plunger rod to eject the cannula through an opening in the outer housing, wherein a releasable seal means operatively couples the plunger rod with a back end of the needle assembly and with the inner housing, and wherein a first engagement means engages the needle assembly with the outer housing at an end of the initial forward motion of the plunger rod; and
a subsequent continuing forward motion of the plunger rod to inject an implant/medicament through the ejected cannula, wherein a seal releasing means disengages the coupling between the needle assembly, the inner housing and the plunger rod;
a first disengagement means for disengaging the first engagement means; and
a second engagement means on the needle holder to permanently arrest the needle assembly in the housing after use.
