摘要： A polyaxial screw head remobilizer for remobilizing a screw body member relative to a head of a polyaxial bone screw includes a barrel body, a handle assembly, an inner shaft, a slide assembly, and a lever. The barrel body includes proximal and distal ends. The distal end includes a plurality of prongs for releasably engaging a plurality of yokes of the polyaxial screw body member to center the inner shaft over the head of the screw. The handle assembly couples to the proximal end of the barrel body. The inner shaft, disposed within the barrel body, includes proximal and distal ends. An engagement feature of the inner shaft mates with pockets of a bushing of the screw body member. The slide assembly is operably coupled to the barrel body and effect translations of the inner shaft. The lever extends from the slide assembly and rotates to actuate the slide assembly.

摘要： An instrument for attaching a driver shaft to a screw assembly using a thrusting motion. The instrument has a main shaft, a locking tube, and a driver shaft. The locking tube is slidably mounted within the main shaft and the driver shaft is slidably mounted within the locking tube. The locking tube is configured to urge a jaw assembly of the instrument into a tensioned engagement with a body member of the screw assembly. A locking mechanism is also included and is configured to lock the driver shaft in a fixed position relative to the locking tube. The locking mechanism may be configured to lock the driver shaft with respect to the locking tube after a distal end of the main shaft engages the screw assembly using the single action.

摘要： An instrument for provisionally tightening a screw body member to a head of a polyaxial bone screw includes a barrel body, an inner shaft, a handle and lever, and a load link assembly. The barrel body includes a distal end with a pair of rotatable tangs configured to engage the screw body member. The inner shaft includes a distal end configured to engage a bushing within the screw body member. The lever pivotally couples to one of the handle and the barrel body. The load link assembly couples to the inner shaft and the lever. Actuation of the lever towards causes the load link assembly to longitudinally displace the inner shaft toward the distal end to contact the bushing and advance the bushing into frictional fit between the screw body member and the head of the polyaxial bone screw.
