Abstract

The invention relates to the technical field of pedicle screw trajectory trepanning devices, in particular to an atlantoaxial screw trajectory opening guide screw tapping device. The atlantoaxial screw trajectory opening guide screw tapping device comprises a kirschner wire, an opening device and a tapping device, the opening device comprises a first guide rod and a first handle, a first guide hole capable of penetrating through the kirschner wire is formed in the first guide rod, a drilling head is arranged on the outer wall of one end of the first guide rod, and the other end of the first guide rod is connected with the first handle; the tapping device comprises a second guide rod, a second handle and a kirschner wire fixing mechanism, a second guide hole capable of penetrating through a kirschner wire is formed in the second guide rod, tapping threads are arranged on the outer wall of one end of the second guide rod, the other end of the second guide rod is connected with the second handle, and the kirschner wire fixing mechanism is arranged on the upper middle portion of the second guide rod. According to the invention, before the pedicle screw is installed, the screw channel of the atlantoaxial is perforated, so that the pedicle screw can be accurately and smoothly installed on the atlantoaxial.

Description

technical field [0001] The invention relates to the technical field of pedicle screw channel opening devices, in particular to an atlantoaxial screw channel opening guide wire tapping device. Background technique [0002] The atlantoaxial vertebrae are the two uppermost segments of the cervical spine, which are at the junction with the skull. This area is densely packed with nerves and blood vessels, and it is close to the breathing and heartbeat center. Atlantoaxial diseases include fractures, tumors, atlantoaxial dislocations, etc. At present, the mainstream method for the treatment of atlantoaxial diseases is posterior reduction, bone grafting, fusion and internal fixation. During the treatment of atlantoaxial diseases, pedicle screws are needed. Because the pedicles of the atlantoaxial are narrow, it is difficult to install pedicle screws on the atlantoaxial. The vertebral body fixes the atlantoaxial vertebrae, causing damage to adjacent vertebral bodies. [0003] The...
