ABSTRACT:
A surgical instrument for use in transjugular venous thromboectomy, comprising a shorter tube and a longer tube in a parallel, back-to-back relationship, each of the tubes having two ends, a first end of said longer tube having a widening provided with a first handle, a second end of the longer terminating in a stopper provided with two axial holes, a first end of the shorter tube having an oblique bending close to a point at which the longer tube widens, a second end of said shorter tube terminating at a distance before the second end of the longer tube; a rod within the longer tube, a first end of which, protruding from the widening, terminates in a second handle, and a second end of which is connected to a clamp which presses two ends of a steel cable passing through the axial holes of the stopper, thereby forming a loop whose eye may be increased or reduced until it is closed, axial displacement of the rod being guided, without rotation, by grooves in the widening of said longer tube; a wire fixed at a first end thereof to the second end of the shorter tube, a second end of the wire being rotatingly secured to a midpoint of the loop; a tubular network, one side of which is attached to the longer tube, one end of a second side of which is fixed to the second end of the shorter tube and a second end of said second side of which is fixed to the steel cable forming the loop, the wire being placed inside of the network; and a screw for fixing position of the rod after movement thereof relative to said first tube.
