<p>PCT No. PCT/AU90/00135 Sec. 371 Date Dec. 2, 1991 Sec. 102(e) Date Dec. 2, 1991 PCT Filed Apr. 6, 1990 PCT Pub. No. WO90/11723 PCT Pub. Date Oct. 18, 1990.A microsurgical instrument comprising a generally cylindrical handpiece (10) split longitudinally to provide two semi-cylindrical parts (12, 13) which are pivotally mounted at a first end thereof, to a central support member (14), for symmetrical pivotal movement at a second end towards and away from each other. A spring (26) biases the parts (12, 13) away from each other. A spindle (11) extends beyond the second end, comprising a pair co-axial shafts (16, 17) which are connected at the first end with respective levers (23, 24) to respective handpiece parts (12, 13) and at the second end to a functional tip of scissor, forceps, or the like, each jaw member of such a tip being connected to only one of the co-axial shafts (16, 17). Squeezing of the handpiece parts (12, 13) together causes simultaneous and symmetrical rotation of the co-axial shafts (16, 17) in opposite directions whereby the jaws of the functional tips are activated symmetrically and in unison.</p> |
