Screw placement system and vertebral arch pedicle screw placement device

The application relates to a vertebral arch pedicle screw placement device. The vertebral arch pedicle screw placement device comprises a bone drill mechanism and a deep pushing mechanism, wherein thedeep pushing mechanism is connected with the bone drill mechanism and used for generating a liner reciprocating kinematic variable; and the bone drill mechanism comprises a bone drill driving deviceand a clamping mechanism connected with the bone drill driving device for drilling. The deep pushing mechanism disclosed by the application provides driving force for liner reciprocating movement of the bone drill mechanism, through combination of the bone drill driving device, the clamping mechanism is subjected to driving control, and the clamping mechanism is used for clamping guide pins, chambering cones, screw taps, vertebral arch pedicle screws and the like required for clamping operation, so that screw placement operation for operations is realized, the operation efficiency and the screwing precision are improve
