Abstract
The invention discloses a skull ring and bar combined external fixing support. The support comprises a plurality of side plates, connecting pillars and sliding blocks, wherein the connecting pillars and the sliding blocks are connected between the side plates. The sliding blocks move in side plate frames, gears on the sliding blocks and inner racks of the side plates are engaged, and thus precision moving can be achieved. The rotating gears drive the whole sliding blocks to move along an arc line, and the side plates have different radians to be selected. Arc-shaped bosses on the two sides of each sliding block are clamped in arc-shaped grooves of the side plates to slide, and thus the accuracy of a trajectory is guaranteed. The sliding blocks and the connecting pillars are both provided with a plurality of bone pins, so that multidirectional positioning is achieved. The sliding blocks can stably slide in a four-side framework through the four-side framework established by the arc-shaped side plates and the connecting pillars, and the bone pins are driven to carry out a bone transport clinical operation along a certain radian; the structure is simple and adjusting is convenient.
