<p>A device for automatic aspiration and/or injection of liquids and/or biological tissue materials consists of a head part (1), on which is arranged a fixed block (2) on which the body (4) of a syringe (3) is mounted. A sliding block (6) is also provided, which can be linked with the piston (8) of the syringe. Said slidable block (6) can for example be moved by means of a cogwheel mechanism or by means of an oil-hydraulic mechanism. A small flexible tube (20) with a needle (21) on its free extremity is provided on the body (4) of the syringe. During agoaspiration, the mechanism making the piston (8) of the syringe slide can for example be actuated by means of a pedal switch.</p> |
