Instrument for artificial insemination, embryo transfer, or sampling of folicular fluids

摘要

The invention relates to an instrument for artificial insemination or the transfer of embryos via the transperitoneal and / or cervical route, or else the removal of follicular fluids from mammals, especially from horses, pigs, sheep, goats and carnivorous cervids. of the type consisting of a syringe formed of a sheath in which slides, sealed a piston, movable in translation, this sheath being protected from the outside by a rigid sheath and being immobilized in a handling handle comprising a rotary member d drive of said piston. The instrument is characterized in that the front end of the sheath (11) is provided with a needle (5,23,25,27) and in that the sheath (14) for protecting the sheath is covered and serves as a guide for a feeler (15) whose length is greater than this sheath but less than that of the sheath (including its needle) to mask or uncover in whole or in part, the needle of the syringe, by simple axial sliding .
