Abstract
This instrument is of the type comprising a hollow body housing a reservoir tube for reproductive components, 4, which receives an ejection piston rod and which is closely enveloped by an external protective sheath 7 having, at its distal end 7b, retaining means 9 inside which the projecting end of the reservoir tube bears. The problem to be solved consists in making it possible to avoid causing any lesions and carrying along any mucus and also to construct instruments of very small diameter. According to the invention, the retaining means 9 on the sheath 7 comprises a terminal 9 with a solid rounded head or distal end 9b and with a blind axial passage 10 open towards the cylindrical body 1 and communicating with the outside at its blind end by means of a lateral transfer orifice 10c. The invention has an advantageous application in the transfer of animal embryos.
