The invention discloses a multi-segment series
connection type external spinal fixation support. The multi-segment series
connection type external spinal fixation support comprises a
percutaneous double-thread
pedicle screw, a working sleeve, screw connectors and embedded type
horizontal and vertical rod locking screws. A
pedicle screw body is arranged inside the
percutaneous double-thread
pedicle screw, pedicle screw double threads are arranged on one side of the pedicle screw body, and a screw easy-breaking self-disconnecting groove is formed in one side of the pedicle screw body. By means of a fixed / pry-adjustable kit design, different kits can be adopted according to the specific condition of
bone fracture segments of a patient, so as to achieve long-stage thoracolumbar vertebral fracture centrum pry-reduction and
distraction fixation, traditional long-stage
open surgery is avoided, and
surgery pain and economic burden can be relieved for patients. By the adoption of an embedded type locking screw structure, the number of external components is reduced greatly,
scratching of clean dressing and clothes of patients by the
tail ends of the locking screws can be avoided during
postoperative rehabilitation, an aseptic environment can be built easily, and the possibility of complications like needle passage infection can be reduced.
