ABSTRACT:
An implanter for implanting treatment pellets beneath the skin of animals comprises a hollow needle (52) through which a drive pin (26) is displaceable to drive a pellet (64) through the needle and in use to a controlled depth below the skin. A forked abutment (54) straddles the needle, being spring urged into a normal location near the rear end of the needle. The abutment (54) is carried by a rearwardly extending rod (56) having a drive member (62) engagable by a thrust member (63) on the drive pin during part of the forward movement of the latter. In use, when the abutment member is against the animal being treated, the final part of the forward movement of the drive pin effects a retraction of the needle, leaving the pellet implanted at the correct depth (FIGS. 4 to 6).
