  • an outer tube with a closed end and a lateral surface, at least one inlet port being provided through said lateral surface, said inlet port located proximate to said closed end and configured to allow said vitreous material to enter into said outer tube;

    an inner tube arranged in said outer tube to relatively move with respect to said outer tube, said inner tube having an opening with a cutting profile, through which said vitreous material can be cut and can enter said inner tube, said inner tube configured to be connected to a suction unit in order to remove by suction any vitreous material entered into said inner tube;

    a drive unit configured for causing said outer tube and said inner tube to move relatively with respect to each other, in such a way that said cutting profile cuts said vitreous material entering said inlet port;

    characterized in that said cutting profile comprises a cutting portion that extends along a direction that is inclined according to a predetermined inclination angle with respect to said longitudinal axis, such that said inclined cutting portion carries out a progressive removal of said vitreous during said relative movement of said inner tube with respect said outer tube.
