Surgical instrument e.g. laminectomy rongeur, for cutting tissue during spinal column surgery, has rotation axis oriented perpendicular to longitudinal extension of shaft, and aligned perpendicular to pivot axis of handle

摘要

The instrument (1) has a disk part (12) longitudinally displaceable relative to the shaft (2), and attached to a handle (6) that is pivotable around a pivot axis (5). The disk part is transferred from a working position, in which the disk part is led to the shaft into a guide (16) i.e. T-groove, into a cleaning position. The disk part is released from the guide and is pivoted relative to the shaft around a rotation axis (21), in the cleaning position. The rotation axis is oriented perpendicular to a longitudinal extension of the shaft, and is aligned perpendicular to the pivot axis.
