Description

Technical Field

[0001] This invention relates to the field of medical auxiliary positioning technology, and in particular to a pedicle puncture positioning device, method, system, electronic device and storage medium. Background Technology

[0002] Currently, surgeries involving pedicle puncture, incision, and screw placement, regardless of whether it's a biopsy, bone cement injection, or pedicle screw placement, require lesion localization during open surgery. Related techniques include fluoroscopic localization for closed surgery, various anatomical localization methods used in open surgery, open navigation localization, 3D-printed template screw placement, and robotic screw placement. Each has its advantages and disadvantages. For example, various anatomical localization methods often struggle to find the entry point due to anatomical variations, and the inability to control the angle of advance also leads to deviations. Fluorescent localization requires repeated fluoroscopy, exposing both the patient and the surgeon to radiation. 3D-printed template screw placement requires individual template fabrication, which is costly and time-consuming. Navigation localization and robotic screw placement require hospital investment, increasing patient costs. In summary, current pedicle localization methods are time-consuming, cumbersome, lack reusability, and are costly. Summary of the Invention

[0044] Currently, surgeries involving pedicle puncture, incision, and screw placement, regardless of whether it's a biopsy, bone cement injection, or pedicle screw placement, require lesion localization during open surgery. Related techniques include fluoroscopic localization for closed surgery, various anatomical localization methods used in open surgery, open navigation localization, 3D-printed template screw placement, and robotic screw placement. Each has its advantages and disadvantages. For example, various anatomical localization methods often struggle to find the entry point due to anatomical variations, and the inability to control the angle of advance also leads to deviations. Fluorescent localization requires repeated fluoroscopy, exposing both the patient and the surgeon to radiation. 3D-printed template screw placement requires individual template fabrication, which is costly and time-consuming. Navigation localization and robotic screw placement require hospital investment, increasing patient costs. In summary, current pedicle localization methods are time-consuming, cumbersome, lack reusability, and are costly.

[0045] Therefore, referring to Figure 1 This invention discloses a pedicle puncture positioning device, comprising a base 100, a horizontal grooved scale 200, and a puncture graduated needle 300. A support 110 is vertically connected to the base 100. The horizontal grooved scale 200 is connected to the support 110 and is horizontally arranged. The puncture graduated needle 300 has graduations and is movably connected to the horizontal grooved scale 200. An angle gauge 330 is located above the horizontal grooved scale 200 and is connected to a balance bar 400. The balance bar 400 is positioned with reference to the pedicle tilt angle measured by preoperative CT scan to determine the distance between the inner segment of the horizontal grooved scale 200 and the puncture graduated needle 300. Optionally, the base 100 can be a fixing seat or a spinous process clamp. The fixation base is horizontally fixed to the spinous process of the patient's back, close to the patient's back, for easy positioning. For open surgery, a spinous process clamp can be used to ensure the stability of the entire pedicle puncture positioning device. It should be noted that, preferably, the horizontal grooved scale 200 has scales on both the upper and lower edges, with a vertical width of 2 cm. The horizontal grooved scale 200 is mounted on the bracket 110 and can slide up and down on the bracket 110. Each side is 8 cm long, with the center of the bracket 110 as the starting point, and the two sides are separated, allowing the puncture needle 300 to move horizontally within the groove. Optionally, a balance bar 400 Kirschner wire is used to reference the angle and determine the distance between the inner side of the horizontal grooved scale 200 and the puncture needle 300.

[0046] Reference Figure 1It is understood that the base 100 fixes the bracket 110 with fasteners, and the bracket 110 is set perpendicular to the base 100. In some embodiments, the base 100 is located on the line connecting the spinous processes. Referring to the parallel distance between the center of the pedicle and the center of the spinous process measured preoperatively, or combined with intraoperative fluoroscopy, the puncture graduated needle 300 is fixed at the midpoint of the inner edge of the pedicle projection. The horizontal grooved scale 200 is moved close to the skin and the fixing screw is tightened, and its scale at the upper and lower edges of the puncture graduated needle 300 is read. Take the same length as the lower section of the puncture graduated needle 300 and fix the angle ruler 330. With reference to the pedicle inclination angle measured by the preoperative CT, place the balance bar 400 at this angle. Read the scale of the balance bar 400 at the upper and lower edges of the horizontal grooved scale 200. Make a puncture channel by taking the balance distance of the balance bar 400 with the puncture graduated needle 300 as the center on the horizontal grooved scale 200. Through the channel, puncture, tapping, screw placement and other clinical work through the pedicle can be performed.

[0047] It should be noted that the pedicle puncture positioning device proposed in this embodiment of the invention has a simple structure and is easy to use. It does not require excessive reliance on intraoperative fluoroscopy equipment, reduces radiation for both doctors and patients, and ensures safety. Furthermore, the device can be reused as a routine tool, has low usage costs, and does not require patients to bear high expenses.

[0048] Reference Figure 1 It is understandable that the end of the puncture graduated needle 300 is provided with a puncture needle tip 310, which is used to puncture the soft tissue of the skin to contact the bony tissue and fix it properly. The proximal end of the puncture needle tip 310 is provided with a blocking collar 320, which is used to limit the puncture needle tip 310 from further penetrating into the bone tissue. The starting point of the graduation coincides with the blocking collar 320. Specifically, the puncture graduated needle 300 is equipped with a puncture needle tip 310, which is located at the tip of the puncture graduated needle 300 and is used to puncture the soft tissue of the skin to contact the bony tissue and fix it properly. The puncture needle tip 310 is about 0.3 cm long, and a stop collar 320 is provided at its proximal end. The stop collar 320 is used to limit the puncture needle from penetrating further into the bone tissue, and the stop collar 320 can also serve as the starting point of the graduations on the puncture graduated needle 300. The upper part of the puncture graduated needle 300 has a 20 cm long graduation, which can be selected as bidirectional marking, that is, graduations are provided on both the left and right sides, and their directions and starting points are different. The upper end of the puncture graduated needle 300 is equipped with a sliding angle ruler 330, which is used to control the angle, and the size of the angle is usually determined by measuring the pedicle external tilt angle on the patient's CT scan before surgery.

[0049] Reference Figure 1 and Figure 2This invention also proposes a pedicle puncture positioning method, applied to a pedicle puncture positioning device, wherein the pedicle puncture positioning device includes a base 100, a horizontal grooved scale 200, and a puncture graduated needle 300. A support 110 is vertically connected to the base 100. The horizontal grooved scale 200 is connected to the support 110 and is horizontally arranged. The puncture graduated needle 300 is provided with graduations and is movably connected to the horizontal grooved scale 200. An angle ruler 330 is provided on the puncture scale and is located above the horizontal grooved scale 200. A balance bar 400 is connected to the angle ruler 330. The balance bar 400 is placed with reference to the pedicle lateral tilt angle measured by preoperative CT scan to obtain the distance between the inner section of the horizontal grooved scale 200 and the puncture graduated needle 300. Optionally, the base 100 can be a fixing seat or a spinous process clamp. The fixation seat is positioned close to the patient's back and horizontally fixed to the spinous process for easy positioning. For open surgery, a spinous process clamp can be used to ensure the stability of the entire pedicle puncture positioning device. The pedicle puncture positioning method includes the following steps:

[0050] S100: Based on a preset CT device, the midline of the spinous process and the outer edge of the superior articular process are measured to obtain the outward tilt angle information and distance information;

[0051] S200: Set the preset ruler to be parallel to obtain the ruler position information;

[0052] S300: Position and move the puncture scale needle 300 according to the distance information, the outward tilt angle information and the scale position information to generate a puncture quadrilateral.

[0053] S400: Puncture is performed according to the outer hypotenuse of the puncture quadrilateral to obtain the puncture result.

[0054] Reference Figure 1In some embodiments, for the patient, preoperative standard anterior fluoroscopy, CT scan, or X-ray results are required to ensure that the anterior and posterior edges of the superior endplate overlap to form a single endplate shadow, with the pedicle shadow located precisely at the lower edge of the superior endplate shadow, and the spinous process equidistant from both pedicles. Then, the base 100 of the pedicle puncture positioning device is fixed to the bilateral posterior superior iliac spine. The horizontal grooved scale 200 on the swing base 100 is balanced with the superior endplate of the vertebral body, with the center line located on the line connecting the midpoints of the pedicles. Then, the puncture needle 300 is moved according to the measured transverse distance or the pedicle projection marked on fluoroscopy to the lateral edge of the pedicle for puncture, often reaching the outer edge of the joint, and initial fixation is performed. Measure the distance from the tip of the puncture needle 300 to the lower edge of the horizontal grooved scale 200. Measure the same distance on the puncture needle 300 above the horizontal grooved scale 200. Place a diagonal rod at the outward tilt angle shown on the CT scan or the theoretical outward tilt angle, intersecting the inner segment of the horizontal grooved scale 200. Then, measure the horizontal distance between the intersection point of the horizontal grooved scale 200 and the puncture needle 300. Next, measure the distance between the intersection point and the horizontal distance of the puncture needle 300 on the outer segment of the puncture needle 300. This forms a parallelogram on the horizontal grooved scale 200 with the puncture needle 300 as its central axis. Perform the puncture along the hypotenuse of the parallelogram on the horizontal grooved scale 200, similar to the hypotenuse of a triangle. The puncture will then intersect at the outer edge of the superior articular process and proceed along the pedicle axis to the vertebral body, completing the puncture.

[0055] Reference Figure 2 and Figure 3 In some embodiments, step S100, which involves measuring the midline of the spinous process and the outer edge of the superior articular process using a preset CT device to obtain the outward tilt angle and distance information, includes the following steps:

[0056] S101: Measure the lateral horizontal distance between the midline of the spinous process and the outer edge of the superior articular process to obtain the distance information;

[0057] S102: Determine the central axis of the pedicle passing through the outer edge of the superior articular process;

[0058] S103: Measure the angle between the central axis and the midline of the spinous process to obtain the outward tilt angle information.

[0059] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments, step S200, which involves setting a preset scale in parallel to obtain scale position information, includes the following steps:

[0060] S201: Perform a projection operation on the pedicle to obtain pedicle projection information;

[0061] S20:2: Project the ruler horizontally according to the pedicle projection information, so that the projection position of the ruler is balanced with the midline of the pedicle projection information, and obtain the ruler position information.

[0062] Reference Figure 2 and Figure 5 In some embodiments, step S300, which involves positioning and moving the puncture needle 300 based on distance information, outward tilt angle information, and scale position information to generate a puncture quadrilateral, includes the following steps:

[0063] S301: Move the puncture scale needle 300 according to the distance information to obtain the puncture distance, wherein the puncture distance is used to characterize the distance between the tip of the puncture scale needle 300 and the scale.

[0064] S302: Mark the scale according to the puncture distance to obtain the target puncture length;

[0065] S303: Set the diagonal bar based on the outward tilt angle information to obtain the intersection information;

[0066] S304: Based on the intersection information, read the horizontal distance between the diagonal bar and the puncture scale needle 300 to obtain the target horizontal information;

[0067] S305: Generate a puncture quadrilateral on the scale based on the target puncture length and target horizontal information.
