ABSTRACT OF THE DISCLOSURE Surgical instrument for transjugular venous thromboectomy, characterised in that it comprises two tubes placed in a parallel, back-to-back relation- ship, one of the ends of the longer tube terminating in a stopper provided with two axial holes, whilst the other end has a widening provided with two side rings in dia- metral opposition, the end of the shorter tube having an oblique bending close to the widening of the longer tube, whilst its other end does not reach the longer tube; a rod within the longer tube, the end of which, protruding from the widening, terminates in a ring, and the free end of which has a clamp which presses the ends of a steel cable passing through the axial holes of the stopper, forming a loop whose eye is increased or reduced until it is closed; the axial displacement of the stem is guid- ed, without rotation, in the widening; a wire fixed to the straight end of the shorter tube, the free end of which is rotatingly secured to the mid point of the loop, as well as a tubular network, one of the openings of which is fixed to that of the shorter tube and the other to the steel cable of the loop, the wire being placed tan- gentially inwards of the network whose generatrix, in contact with the longer tube, is joined thereto; a screw for fixing the moving position of the rod.
