The instrument is used in particular on the ovine, caprine, bovine or equine species and is characterised in that it consists of a rigid probe (5) comprising two tangential channels (51, 52) defined by two conduits of different diameters, lodged one inside the other, one of the conduits (52) being connected to a suction pump, the other (51) serving as a guide for a punctiform catheter, the base of the latter being notched radially in order to permit visualisation, with endoscopy, of the displacement of the needle (12). <IMAGE> |
