1. Surgical instrument, in particular an arthroscopy punch, with a jaw (22), comprising a stationary jaw part (3) and a movable jaw part (10) which, by pivoting of a pivotable grip part (6), is displaceable relative to the stationary jaw part (3), between a closed position and an open position, in a slotted guide (26) along a curved guide path, wherein the surgical instrument (1) is designed as a sliding shaft instrument, comprising a shaft (2) assigned to the stationary jaw part (3) and a sliding part (9) which is longitudinally displaceable in translation along the shaft (2), by pivoting of the grip part (4, 6) relative to the shaft (2), and which is adjustable between a working position, in which it is guided longitudinally displaceably on the shaft (2) in a guide (13) and is coupled in an articulated manner to the movable jaw part (10) for adjusting the jaw part (3, 10) between the closed position and the open position in a guided displacement movement of the sliding part (9), and a cleaning position, in which the sliding part (9) is uncoupled from the movable jaw part (10), freed from the guide (13) and pivotable about a rotation axis (18) relative to the shaft (2) and relative to the movable jaw part (3), and in that manually activatable locking means (21) are assigned to the sliding part (9), with which locking means (21) the sliding part (9) can be secured in its working position against inadvertent transfer to the cleaning position. |
