An ophthalmic surgery instrument

An ophthalmic surgery instrument, comprising:

• a handling unit having a longitudinal axis,
• a surgical module provided on the handling unit and extending away therefrom along the longitudinal axis thereof, and
• a shaft at least partially surrounding the surgical module,
• wherein the surgical module and the shaft are mutually movable relative along the longitudinal axis of the handling unit,
• a guiding element arranged at a distal end of the handling unit, the guiding element being provided with a central bore that is traversed by the surgical module and the shaft extending from the handling unit outwardly along the longitudinal axis thereof, wherein the handling unit comprises
• an actuation unit comprising a plurality of actuation arms arranged around the longitudinal axis of the handling unit, and
• a driving unit arranged to, upon manual actuation of the actuation unit, drive the shaft relative to the guiding element back and forth through the central bore of the guiding element, the driving unit including a radial-to-axial linkage constructed and arranged to convert a radial movement provided by the actuation unit through the actuation arms to axial movement of the shaft with respect to the surgical module, wherein the radial-to-axial linkage comprises a set of pivoting joint elements, each pivoting joint element having a first end and a second end, said second end being associated with the shaft,
• wherein the number of pivoting joint elements corresponds with the number of actuation arms, and
• wherein the first end of each pivoting joint element is pivotably connected to a corresponding actuation arm.
