Description

Technical Field

[0001] The present application relates to the field of medical image processing, and in particular to a visually interactive PAO (congenital hip dislocation) surgical osteotomy adjustment planning method, electronic equipment and medium based on VTK (The Visualization Toolkit). Background Art

[0002] PAO surgery loosens the acetabulum by performing osteotomy around the acetabulum, then rotates the acetabulum outward and forward to change its direction and improve the coverage of the acetabulum on the femoral head, thereby reducing joint wear and delaying or even avoiding long-term joint replacement.

[0003] Since acetabular dysplasia is a defect in the structure of the acetabulum, it leads to instability of the hip joint, resulting in early wear of the acetabular cartilage, especially in the lateral weight-bearing area of ​​the acetabulum. Structural defects lead to cartilage wear and pain, followed by early osteoarthritis. The significance of surgery is to change the structure of the acetabulum. Only pain caused by structural problems can be relieved after surgery.

[0004] The success of PAO surgery is generally determined by measuring several important anatomical parameters. After the doctor adjusts the acetabulum during surgery, it needs to be initially fixed, and then an X-ray is taken to confirm whether the acetabulum is in the right position.

[0005] In current PAO surgery, doctors use CT (computer tomography) data to analyze the patient's acetabulum structure before surgery to formulate a surgical plan. During surgery, after the doctor has made adjustments, the doctor needs to temporarily fix the acetabulum and take X-rays to confirm whether the acetabulum is in the right position. During this process, multiple adjustments may be required until the acetabulum is in place. However, for unskilled doctors, multiple adjustments are required, which prolongs the operation time and causes excessive X-ray radiation, affecting work efficiency and making the operation difficult.

[0044] In order to overcome the above-mentioned defects that currently exist, the present embodiment provides an osteotomy adjustment planning method based on visualized images, including: obtaining a pelvic model reconstructed based on three-dimensional medical images; calculating at least one anatomical parameter of the pelvic model based on feature points; receiving interactive instructions based on the displayed pelvic model and anatomical parameter feedback; adjusting the acetabulum angle in the pelvic model according to the received interactive instructions to keep the anatomical parameters within a preset range.

[0045] In this embodiment, the visual and interactive acetabulum adjustment planning of PAO surgery can be effectively realized, the acetabulum adjustment process during the operation can be simulated in advance, and the acetabulum position and necessary anatomical parameters of the two-dimensional slices can be updated in real time during the adjustment process, providing a reference for the rapid and one-step acetabulum adjustment during the operation, thereby improving work efficiency and operability.

[0046] Specifically, as an embodiment, Figure 1 As shown, the method for osteotomy planning based on visualized images provided in this embodiment mainly includes the following steps:

[0047] Step 101: Obtain a pelvic model and the acetabulum part after osteotomy planning.

[0048] In this step, a pelvic model reconstructed based on three-dimensional medical images and the acetabulum to be adjusted after osteotomy planning in the pelvic model are obtained.

[0049] Specifically, the point data model and voxel model processed by the osteotomy planning are displayed in the three-dimensional window and the slice three-view window respectively.

[0050] Step 102: Calculate the anatomical parameters of the pelvic model.

[0051] In this step, at least one anatomical parameter of the pelvic model is calculated according to the feature points.

[0052] In this embodiment, the anatomical parameters may include any one or more of the anteversion angle, abduction angle, LCE angle and femoral head coverage of the acetabulum position, but this embodiment does not specifically limit the type of anatomical parameters and can be set accordingly according to actual needs.

[0053] Specifically, when the acetabulum is adjusted, these anatomical parameters are calculated and updated in real time. Generally, the range of each anatomical parameter is: anteversion angle 5°-20°, abduction angle 40°-47°, LCE angle 25°-39°, and femoral coverage>75%. However, this embodiment does not specifically limit the values ​​of the anatomical parameters, and can be set accordingly according to actual needs.

[0054] Step 103: Adjust the rough angle of the acetabulum in the pelvic model according to the received rough adjustment interaction instruction.

[0055] In this embodiment, reference Figure 2 As shown, in the coordinate system of the pelvic model, a rotating coordinate system for rotating the acetabulum is established with the center point of the acetabulum as the origin, the camera lens facing in the reverse direction as the positive direction of the Z axis, and the camera facing upward as the positive direction of the Y axis.

[0056] In this step, a coarse adjustment interactive instruction based on the displayed pelvic model and anatomical parameter feedback is received, and the acetabulum is rotated with the acetabular fossa center point as the rotation point according to the received coarse adjustment interactive instruction to adjust the coarse angle of the acetabulum.

[0057] Specifically, the rough adjustment of the acetabulum utilizes the interaction of dragging an operating device (e.g., a mouse) to realize rapid rotation adjustment of the acetabulum. The cut acetabulum portion is rotated about the rotation center of the acetabulum. After confirmation, the real-time acquisition of the mouse pixel position (u m ,v m ), get the new mouse pixel position (u) when the mouse moves m+1 ,v m+1 ) Displacement distance (d u ,d v )=(u m+1 -u m ,v m+1 -v m ).

[0058] At this time, in the coordinate system of the three-dimensional model, the center point of the acetabulum is taken as the origin, the camera lens is facing in the opposite direction as the positive direction of the Z axis, and the camera is facing upward as the positive direction of the Y axis to establish the coordinate system. u ,d v) respectively correspond to rotation around the Y axis and rotation around the X axis. In VTK, you can directly obtain the direction vector of the camera That is, the Z axis and the camera's upward direction vector That is, the Y axis. Through the vector cross multiplication formula, the X axis can be obtained as: Here the displacement distance of the mouse pixel is specified (d u ,d v ) is rotated by 1 radian for every 50 pixels.

[0059] Knowing the rotation angle and rotation axis, according to Rodrigues formula v rot =cosθ·v+(1-cosθ)(v·k)k+sinθ·k×v, where v is the coordinate of the model point before rotation and k is the rotation matrix, which is and θ is the rotation angle, v rot The rotated coordinates of the model point.

[0060] Step 104: Adjust the fine angle of the acetabulum in the pelvic model according to the received fine adjustment interactive instruction.

[0061] In this step, a fine-tuning interactive instruction based on the displayed pelvic model and anatomical parameter feedback is received, and the acetabulum is rotated around the normal vector of the acetabulum slice cutting plane according to the received fine-tuning interactive instruction to adjust the fine angle of the acetabulum in the pelvic model.

[0062] In this embodiment, the slice may be a two-dimensional slice of a transverse plane, a coronal plane, or a sagittal plane, but is not limited thereto and may be adjusted and selected accordingly according to actual needs.

[0063] Specifically, the acetabulum fine adjustment is designed to allow the doctor to make small rotation adjustments in all directions through buttons after the rough adjustment. Figure 3 As shown, Figure 3 The two buttons below control the rotation direction. Different from the rotation coordinate system established by the camera position in the coarse adjustment, the rotation coordinate system in the fine adjustment depends on the direction of the cutting plane and rotates with the normal of the plane as the rotation axis. In this embodiment, the cutting plane directions of the transverse, coronal, and sagittal planes are defined as These three directions are parallel to the XY, XZ, and YZ planes, respectively. Therefore, fine adjustment rotates the three tangent planes based on the Z axis, Y axis, and X axis, respectively. Each click of fine adjustment rotates the angle by 0.01 radians.

[0064] Step 105: Confirm the adjustment plan.

[0065] In this step, confirm and save the adjustment plan. If you need to modify it later, you can return to the adjustment module for adjustment. The acetabulum position can be reset at any time during the adjustment process.

[0066] As an optional embodiment, in order to reduce the number of times the acetabulum is adjusted, it can be directly adjusted according to the anatomical parameters required by the doctor, and a unique rotation direction can be confirmed by setting the anteversion angle and the abduction angle.

[0067] The acetabulum orientation is known to be The anteversion angle is the angle between the projection of the acetabular axis on the sagittal plane and the patient's longitudinal axis. Assume that the initial vector is the patient's longitudinal axis, i.e., the y-axis. The tilt angle set by the direction planner is θ. According to the tilt angle, the initial vector needs to be rotated around the X axis. The abduction angle is the angle between the acetabular axis and the projection of the patient's longitudinal axis on the coronal plane. Assuming that the abduction angle set by the planner is β, according to the abduction angle, the vector after the first anteversion rotation continues to rotate around the Z axis. The target vector is The final required original acetabular orientation To the target location The rotation matrix of . The rotation axis can be obtained by Obtain the rotation angle. Use the same method as above to obtain the rotation equation through Rodrigues' formula. During this period, use interpolation to calculate the path of the vector change in the whole process, and display it in time sequence to achieve the effect of animation display adjustment angle.

[0068] The following specifically describes the operational flow of implementing osteotomy adjustment planning using the osteotomy adjustment planning method based on visualized images as in the above embodiment.

[0069] 1. The operator, i.e. the doctor, uses a computer to reconstruct the pelvis and femur models based on the patient's preoperative CT three-dimensional medical images and osteotomy planning.

[0070] 2. The acetabulum to be adjusted after osteotomy planning is displayed, and the two-dimensional slice display windows of the cross section, coronal plane, and sagittal plane are displayed.

[0071] 3. Calculate the current anteversion angle, abduction angle, LCE angle and coverage rate based on the acquired feature points and point cloud technology, where reference Figure 4 As shown in the figure, the LCE angle is defined as the angle between the line through the center of the acetabulum at the most lateral part of the acetabulum and the line parallel to the midline of the human body. o It will keep changing, and the point with the largest absolute value on the surgical side in the X-axis direction needs to be recalculated using point cloud technology as p o (x o,y o ,z o ). The human body midline vector is (x m ,y m ,z m ), the center point of the acetabulum is (x c ,y c ,z c ). According to the vector dot multiplication formula, we can get

[0072] 4. The doctor makes a rough adjustment of the acetabulum. Move the mouse to the 3D window, press the left button of the mouse to adjust the pelvic model to the appropriate sight line position, and press the right button of the mouse to adjust the acetabulum angle. The mouse moves up and down to rotate the model around the X axis, and the mouse moves left and right to rotate the model around the Y axis. Observe the data bar during the adjustment process and try to keep all anatomical parameters within a reasonable preset range.

[0073] 5. After making rough adjustments, doctors usually need to make some fine adjustments. Doctors can make fine adjustments on different slice windows by analyzing the more familiar two-dimensional slices. Figure 3 As shown, when the left button is pressed, the acetabulum rotates counterclockwise around the slice normal vector, and when the right button is pressed, the acetabulum rotates clockwise around the slice normal vector.

[0074] 6. Figure 5 The 3D window schematic diagram after the acetabulum adjustment is completed is shown. After the adjustment, the anatomical parameters that can be obtained in this embodiment are as follows: anteversion angle 8.5°, abduction angle 40.7°, LCE angle 35.1°, coverage rate 76.3%. These parameters have been adjusted to the appropriate preset range (theoretical value range).

[0075] 7. Confirm and save the adjustment plan. If you need to modify it later, you can return to the adjustment module to make adjustments. The acetabulum position can be reset at any time during the adjustment process.

[0076] 8. After entering the adjustment navigation during surgery, the doctor can see the relative position of the acetabulum and pelvis in real time in the navigation window, and the navigation interface will provide a guidance model for adjustment planning. Figure 6 As shown, the target acetabular adjustment position and the current position of the acetabulum are shown respectively. The doctor needs to adjust the actual acetabular part to a position that coincides with the target acetabular adjustment position of the guidance model as much as possible.

[0077] Based on the above operations, the following beneficial effects can be achieved:

[0078] 1) Provides convenient and accurate visual acetabulum simulation adjustment function;

[0079] 2) Select the appropriate adjustment angle based on the real-time updated anatomical parameters, reducing the measurement and evaluation after intraoperative filming;

[0080] 3) It provides real-time updated 2D slice images, greatly reducing the need for intraoperative X-rays;

[0081] 4) It provides a reference for intraoperative acetabulum adjustment, making it easier for doctors to adjust the acetabulum to the appropriate angle in one step, reducing the difficulty of surgery, reducing operation time, and improving work efficiency and operability.

[0082] The osteotomy adjustment planning method based on visualized imaging provided in this embodiment can effectively allow doctors to rotate the acetabulum on the reconstructed three-dimensional model of the pelvic model after osteotomy, and can calculate the pelvic femoral parameters. The present application can plan the acetabulum adjustment plan before surgery, and will display the changes in anatomical parameters in real time during the simulation adjustment process, and save the plan after the parameters are adjusted to the appropriate range. When adjusting the navigation, the present application can make quick one-step adjustments according to the plan, which can not only save time, but also reduce the damage caused by radiation, thereby improving work efficiency and operability.
