Background
Because the traction and the stripping of the spine minimally invasive surgery on soft tissues are less, the postoperative pain can be reduced, and the recovery time is shortened; and the minimally invasive spine surgery performs limited excision on the bony structure, so that the possibility of post-operation spine instability is reduced. Thus, minimally invasive spinal surgical techniques have evolved rapidly over the last decade. Minimally invasive spinal surgery mainly comprises minimally invasive underpass microscopic disc nucleus pulposus excision, minimally invasive lumbar semi-laminectomy, trans-foraminal lumbar interbody fusion, lateral lumbar interbody fusion and minimally invasive posterior fixation techniques. Compared with the traditional open surgery, the minimally invasive tunnel positioning is needed under the perspective guidance, so that although the minimally invasive surgery of the spine is less traumatic, the radiation dose received by a surgeon is 10 to 12 times that of the traditional surgery.
In the conventional minimally invasive spine surgery, a doctor performs surgical positioning by visually observing the angles and distances of surgical instruments in the righting and lateral X-ray images relative to the path of a surgical object according to the experience and skill of the surgery and adjusting the surgical instruments to be coincident with the ideal surgical path. This method relies heavily on the surgical experience and skill of the physician. The difficulty of surgery is great due to the anatomical complexity of the spine and the limitations of the means by which the doctor observes the spine; the spine drilling precision is not high, and the spine drilling operation deviates from a set path; in addition, the repeated use of X-ray fluoroscopy exposes doctors, patients and related personnel to radiation for a long period of time. Therefore, the invention aims to provide the improved auxiliary spine minimally invasive surgery path positioning device which is simple and flexible to operate, wide in application range and capable of accurately adjusting the position.

The invention provides a device for assisting in adjusting the vertebral pedicle screw implantation operation path of a spinal column, which comprises the following specific implementation steps: the device is fixed on an operating table or a trolley before operation, so that a plane formed by the transverse direction and the longitudinal direction is parallel to the surface of the operating table as much as possible, and an operation path determined by the locator is positioned in the shooting range of the C-arm.
According to the X-ray image shot in the operation process, the deviation between the path positioner and the operation planning path is calculated by adopting spine minimally invasive operation path navigation software, and the position of the path positioner is adjusted by adjusting the transverse translation assembly, the longitudinal rotation assembly and the transverse rotation assembly so as to be consistent with the operation planning path (namely, the axes of the small circular ring 501 and the large circular ring 506 are coincident with the planning path): adjusting the locking screw 201 in the transverse translation assembly 2 allows for length adjustment in the X direction; adjusting the locking screw 309 in the longitudinal translation assembly 3 allows for length adjustment in the Y-direction; the locking screw 401 in the longitudinal rotating assembly 4 is adjusted to rotate around the longitudinal direction, and before rotation, the angle indicator 602 in the angle indicating assembly 6 can clear the angle, and the rotated angle is transmitted in real time in the rotating process, so that the angle adjustment of doctors is facilitated; the fine adjustment knob 503 in the transverse rotation assembly 5 can rotate around the transverse direction, and before rotation, the angle indicator 602 in the angle indication assembly 6 can clear the angle, and the rotated angle is transmitted in real time in the rotation process, so that the angle adjustment of doctors is facilitated. After the path positioner is consistent with the planned path of the operation, the lifting sliding component is adjusted, the distance between the lower surface of the positioner and the human body is adjusted, and the error of the entry channel of the operation guide needle is reduced.
After the first path positioning is finished, the lifting sliding component is adjusted to shorten the contact between the positioner and the lower surface of the human body and implant the guide needle, the sliding component is lifted again, the distance between the lower surface of the positioner and the human body is increased, and the operating table, the longitudinal translation component or the transverse translation component is adjusted, so that the positioning path of the positioner reaches the path channel of the next time, and the next path positioning is performed. According to the operation requirement, the operation bed or the longitudinal translation component can be adjusted for a plurality of times, and the steps are repeated until all the path guide pins are implanted. By this way, the positioning of a plurality of parallel paths is completed, and the adjustment time of the C-arm and the rotating assembly can be greatly reduced, thereby reducing the operation time, improving the operation efficiency and reducing the radiation in operation.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
