Abstract:
1. An endoprobe for microsurgical procedures comprising: a hand-piece comprising a motor; a cannula assembly coupled to the hand-piece; a transmission system coupling the motor to the cannula assembly; the cannula assembly comprising: an outer tube able to rotate about a longitudinal axis; an inner tube concentric with the outer tube, able to rotate about the longitudinal axis; the outer tube and the inner tube each having a proximal end and a distal end; wherein the transmission system rotates the outer tube in a first direction and the inner tube in a second, opposing direction about the longitudinal axis; a proximal space formed between the proximal ends of the outer tube and the inner tube comprises at least a portion of the transmission system; the transmission system extending into the proximal space and being located between the inner tube and the outer tube in a radial direction; and the transmission system comprises at least one gear-assembly which couples the motor to the inner side of the outer tube and to the outer side of the inner tube.
