Abstract

A handle (2) for a surgical instrument is described. The handle comprises a housing (4) for attachment to an outer shaft of a surgical instrument and defining a longitudinal axis. An adjustment member (6) comprises a first bevel gear (12) mounted for rotation about an adjustment axis perpendicular to the longitudinal axis. A second bevel gear (26) is engaged with the first bevel gear and mounted to rotate about an axis parallel to the longitudinal axis. A translatable member (36) is provided for attachment to an inner member of a surgical instrument and is configured to move relative to the housing along the longitudinal axis in response to rotation of the second bevel gear. In one embodiment the handle is for a minimally invasive surgical instrument having a segment string at its distal end. The configuration of the handle allows one handed use. The adjustment member can be operated by the same hand which is holding the handle. A surgical retractor instrument (44) including the handle is also described
