A microsurgical instrument that can slide over a surgical suction instrument and comprises a grasper or a micro-scissor for cutting at the distal end, a lever at the proximal end to actuate the jaws of the grasper or the blades of the micro scissor. The disclosed microsurgical instrument may be locked to the surgical suction instrument or may be rotated on the long axis on the surgical suction instrument. The disclosed instrument can be placed by sliding over the surgical suction instrument without the need for disconnecting the surgical suction instrument from the suction hose.
