Title: SURGICAL REPOSITIONING INSTRUMENT
Abstract:
A surgical repositioning instrument (10) for lowering and fixing a fixing rod (148) in the tulip head (130) of a bone screw (132) comprises a coupling sleeve (14) having at least two distal latching arms (18) for coupling on the tulip head of the bone screw. A locking sleeve (22) is arranged on the coupling sleeve such that it can be displaced longitudinally between a releasing position and a locking position. A rod presser (24) is used to contact and lower the fixing rod. A handle part (26) has a through recess (32) in which the locking sleeve, the coupling sleeve and the rod presser are arranged. On the handle part (26), an actuation lever (40) is pivotally mounted to push the rod presser forward relative to the coupling sleeve. In the releasing position of the locking sleeve (22), the proximal end (22b) of the locking sleeve projects out of the through recess (32) in an axial direction over the handle part (26) and the locking sleeve can be moved into its locking position irrespective of the rod pusher (24) by means of an axially directed force (F) applied to its proximal end (22b).
