Device for the ventral screwing from dens - fractures with a compression bolts

摘要

Device for ventrally screwing dens fractures with compression screws, comprising a targeting pipe gauge (1) with two targeting pipe sleeves (11) which are pivotably connected to one another via a joint (12) and can be fine-adjusted via an actuation member (13, 14, 15) in a defined angular region. The targeting pipe gauge (1) is aligned and adjusted at the start of the operation under radiographic control, the remainder of the operation taking place without permanent monitoring by an image converter. Introduction of the two compression screws (100) takes place in an exactly predetermined, optimum position, the soft tissues in the operation field being protected against accidental injury during the operation by the targeting pipe sleeves (11).
