Embodiment Construction

[0011] During the spinal pedicle screw implantation operation, the spinous process of the spine is clamped with the spinous process clamp 16, and the positions of the right slider 3 and the left slider 13 are adjusted according to the individualized data of the spine CT to make the right semicircular The needle entry hole 1 and the left semicircular needle entry hole 15 coincide with the needle entry points on both sides of the spine respectively, adjust the position of the right arc slider 7 on the right horizontal plane angle marking ruler 5 and the left arc slider 10 Position on the horizontal plane angle marking ruler 11 so that the marked angles are the same as the horizontal plane angles of the central axis of the pedicles on both sides respectively, adjust the position of the right longitudinal slider 4 on the right sagittal plane angle marking ruler 6 and the left longitudinal slider 4 The position of the block 12 on the left sagittal plane angle marking ruler 9 is such...

Abstract

The invention provides a method for marking a transverse section angle and a sagittal section angle of a bilateral pedicle screw, belongs to the technical field of medical treatment, and aims to solve the problem that a method for marking the transverse section angle and the sagittal section angle of the bilateral pedicle screw accurately according to the transverse section angle and the sagittal section angle of the central axis of the bilateral pedicle is absent in a human spine pedicle screw implanting operation process. The main point of the adopted technical scheme is that a pre-operation CT (computed tomography) image data is used for individualized accurate measurement of the transverse section angle and the sagittal section angle of the central axis of the bilateral pedicle of a patient spine, during operation, the transverse section angle and the sagittal section angle for implanting of the bilateral pedicle screw are marked accurately through scale on an instrument according to measured data, and the operation is guided for smooth performing. The main application is that the transverse section angle and the sagittal section angle of the bilateral pedicle screw are marked quickly and accurately according to the individualized CT data of the spine, and the transverse section angle and the sagittal section angle of the central axis of the bilateral pedicle are consistent with the transverse section angle and the sagittal section angle of the bilateral pedicle screw, so that the operation effect is improved, and complication is reduced.

Description

Technical field: [0001] The invention relates to an instrument for marking the horizontal plane angle and the sagittal plane angle of bilateral pedicle screws during the human spinal pedicle screw implantation operation, belonging to the field of medical instruments. Background technique: [0002] Human spinal pedicle screw implantation internal fixation surgery is widely used in spinal trauma, spondylolisthesis, deformity and degeneration and other diseases. Pedicle screw implantation surgery requires pedicle screw implantation along the central axis of the pedicle. The central axis of the pedicle of the human spine has a horizontal plane angle and a sagittal plane angle. Therefore, it is necessary to accurately mark the horizontal plane angle and the sagittal plane angle of the pedicle screw implantation during the operation, so that the horizontal plane angle of the pedicle screw implantation The horizontal and sagittal angles are the same as the horizontal and sagittal a...
