Abstract
The present disclosure relates to a screw surgical device and method and can provide a screw surgical device and method, which use Doppler ultrasound using surgery in which pedicle screws are used, so as to sense the vertebral artery, and thus can reduce risk of the vertebral artery damage and amount of radiation exposure. Particularly, the present disclosure can provide the screw surgical device and method, which use Doppler ultrasound using surgery so as to monitor blood flow information about arterial blood adjacent to an insertion path of a pedicle screw, and thus can improve accuracy of pedicle screw fixation.
Claims16
A screw surgical device comprising:
- an instrument part which includes a gear shift and a taper which are inserted from a target patient's skin to a predetermined point in a pedicle to form an insertion path and a screw which is inserted and fixed into a spine through the insertion path;
- a sensor part which monitors blood flow information about blood flow passing through an artery adjacent to the insertion path using an ultrasound probe installed at one end of the instrument part;
- and
- an information providing part which senses a vertebral artery (Vertebral artery, VA) on the basis of the blood flow information and provides guide information about the insertion path.
A method for controlling a screw surgery device comprising:
- inserting an instrument part which includes a gear shift and a taper which are inserted from a target patient's skin to a predetermined point in a pedicle to form an insertion path and a screw which is inserted and fixed into a spine through the insertion path;
- monitoring blood flow information about a blood flow passing through an artery adjacent to the insertion path using an ultrasound probe installed at one end of the instrument part;
- and
- sensing a vertebral artery (Vertebral artery, VA) on the basis of the blood flow information and providing guide information about the insertion path.
