technical field

The invention relates to the technical field of medical devices, in particular to an integrated pedicle screw channel detection device.

Background technique

As a vertebrate, the function and significance of the spine to the human body is very important. The spine of a normal human body is located in the middle of the back, the upper end is connected to the skull, and the lower end reaches the tip of the coccyx. It is the axial skeleton of the human body. , protection and movement functions. In addition, the spine also protects the spinal cord inside, which is the center of many simple reflexes, so it can be said that the spine is one of the most important bone structures in the human body.

It is known in spine surgery to implant pedicle screws into the vertebral body for stabilization and/or strengthening of the vertebral body to treat spinal disorders such as those caused by tumors, aging processes, genetic causes, trauma or degenerative diseases. Ideally, the pedicle screw is positioned such that the screw is fully received in the root of the articular process of the vertebral body. The screw should not protrude from the root, especially in the area of the vertebral foramen or spinal cord. Incorrect positioning can lead to instability of the vertebral body being treated and in the worst case possible neurological damage and thus, for example, severe paralysis. Therefore, the positioning of the pedicle screw is very important.

At present, in the pedicle screw implantation operation, before the pedicle screw is implanted, there is no detection device for marking the position of the screw track during intraoperative fluoroscopy, which is inconvenient for the pedicle screw to be placed in the screw track.
