A microsurgical instrument comprises a generally cylindrical handpiece (10) split longitudinally to provide two semi-cylindrical parts (12, 13) which are pivotally mounted at one end thereof, to a central support member (14), for symmetrical pivotal movement at the other 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 of co-axial shafts (16, 17) which are connected at the first end via 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, type construction each jaw member 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 tip are similarly activated symmetrically and in unison. |
