[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] The serial numbers assigned to components in this application, such as "first" and "second", are used only to distinguish the described objects and have no sequential or technical meaning.

[0045] First, before introducing the technical solutions of the embodiments disclosed in this application, the background technology or technological evolution on which the embodiments of this application are based will be introduced. With the development of medical technology, hip replacement surgery, as a surgical procedure to replace a damaged hip joint with an artificial acetabulum and an artificial femoral head, is becoming increasingly widely used. Before performing hip replacement surgery, preoperative planning is required, that is, preoperative simulation of the process of placing the acetabular prosthesis and femoral head prosthesis to be replaced into the hip joint. During the preoperative planning process, when simulating the placement of the acetabular cup in the acetabular fossa, it is necessary to observe the remaining bone volume information of the acetabular wall corresponding to the acetabular fossa, that is, the thickness information of the acetabular wall. In other words, when placing the acetabular cup in the acetabular fossa, the acetabular fossa needs to be milled to ensure that the acetabular cup can be accurately placed in the acetabular fossa; after the acetabular cup is accurately placed in the acetabular fossa, it is necessary to observe the remaining bone volume of the acetabular wall after milling. In traditional technology, the thickness information of the acetabular wall is usually measured by measuring primitives or by measuring with actual measuring tools. However, traditional methods for determining the thickness of the acetabular wall require rotating the hip joint model when determining the thickness at different locations, making it impossible to achieve a holistic view of the thickness information at all locations of the acetabular wall. To address this, this application proposes a method for preoperative planning and display of the hip joint.

[0046] The technical solution of this application and how the technical solution of this application solves the technical problem are described in detail below with specific embodiments.

[0047] The preoperative planning and display method for hip joint surgery provided in this application can be applied to computer devices, which may include, but are not limited to, industrial computers, laptops, and tablets. The internal structure diagram of the computer device can be as follows: Figure 1 As shown, the computer device includes a processor, memory, communication interface, display screen, and input devices connected via a system bus. The processor provides computing and control capabilities. The memory includes non-volatile storage media and internal memory. The non-volatile storage media stores the operating system and computer programs. The internal memory provides an environment for the operation of the operating system and computer programs in the non-volatile storage media. The communication interface is used for wired or wireless communication with external terminals; wireless communication can be achieved through Wi-Fi, mobile cellular networks, NFC (Near Field Communication), or other technologies. When executed by the processor, the computer program implements a method for displaying preoperative hip joint planning. The display screen can be an LCD screen or an e-ink screen. The input devices can be a touch layer covering the display screen, buttons, a trackball, or a touchpad on the computer device's casing, or an external keyboard, touchpad, or mouse.

[0048] In one embodiment, such as Figure 2 As shown, a method for preoperative planning and display of hip joint surgery is provided. This embodiment illustrates the application of this method to a computer device. In this embodiment, the method includes the following steps:

[0049] Step 200: Display the hip joint model on the model display interface; the hip joint model includes the acetabulum.

[0050] The computer device's display interface includes a model display interface, which is used to display the hip joint model. The hip joint model can be acquired through medical scanning equipment and transmitted to the computer device. This medical scanning equipment can be a computed tomography (CT) scanner or an magnetic resonance imaging (MRI) scanner, among others. After obtaining the hip joint model through scanning, the medical scanning equipment transmits the model to the computer device, which then displays it on the model display interface. The hip joint model includes the acetabulum, which is used to house the acetabular cup model.

[0051] Step 210: In response to the operation of placing the acetabular cup model into the acetabular fossa, display the acetabular wall thickness information in a first form on the polar coordinate graph of the acetabular wall thickness display interface. The acetabular wall thickness information refers to the acetabular wall thickness information at the position of the acetabular cup model after the simulated acetabular cup model is placed into the acetabular fossa.

[0052] The acetabular cup model can be pre-set and stored by the user on a computer device. In the model display interface, the user retrieves the acetabular cup model and moves it to the acetabular fossa. This embodiment does not limit the specific method by which the user retrieves the acetabular cup model.

[0053] In an optional embodiment, the model display interface includes a cup model selection control. The computer device displays the cup model selection interface in response to a trigger operation (click operation) on the cup model selection control. The cup model selection interface includes multiple cup models to be selected. In response to a selection operation on a cup model to be selected, the selected cup model is displayed on the model display interface. The user moves the cup model displayed on the model display interface to the acetabulum.

[0054] The computer device's display interface also includes an acetabular wall thickness display interface, which displays a polar coordinate graph. In response to the user's operation of placing (moving) the acetabular cup model into (moving) the acetabular fossa, the computer device displays the acetabular wall thickness information in a first form on the polar coordinate graph of the acetabular wall thickness display interface. That is, after simulating placing the acetabular cup model into the acetabular fossa, the computer device mills the area of ​​interference between the acetabular wall and the acetabular cup model—that is, the area of ​​the acetabular wall that overlaps with the acetabular cup model—so that the acetabular cup model is completely placed within the acetabular fossa. The thickness information of the milled acetabular wall is the information displayed on the polar coordinate graph of the acetabular wall thickness display interface. The first form can be different colors or different labels, that is, using different colors or different labels to represent different acetabular wall thickness information. This embodiment does not limit the first form, as long as it can distinguish different acetabular wall thickness information.

[0055] In an optional embodiment, initially, the acetabular wall thickness display interface and the model display interface can be simultaneously displayed on the computer device interface. When no acetabular cup model is placed in the acetabular fossa, the polar coordinate graph in the acetabular wall thickness display interface is empty, or displays the previous acetabular wall thickness information. In response to the user's operation of placing the acetabular cup model into the acetabular fossa, the computer device displays the acetabular wall thickness information in a first form in the polar coordinate graph of the acetabular wall thickness display interface.

[0056] In another alternative embodiment, initially, the acetabular wall thickness display interface and the model display interface are not displayed simultaneously on the computer device interface; that is, initially, only the model display interface is displayed on the computer device interface. In response to the user's operation of placing the acetabular cup model into the acetabular fossa, the computer device displays the acetabular wall thickness display interface, and simultaneously displays the acetabular wall thickness information in a first form in a polar coordinate graph within the acetabular wall thickness display interface. The acetabular wall thickness display interface may be floating above the acetabular wall thickness display interface, and the acetabular wall thickness display interface may be movable.

[0057] In an optional embodiment, the acetabular wall thickness display interface is as follows: Figure 3 As shown in the figure, the acetabular wall thickness information is divided into three intervals: 0-2mm, 2-5mm, and greater than 5mm. These three intervals are identified by different colors in the polar coordinate image.

[0058] The preoperative planning and display method for hip joint provided in this embodiment displays a hip joint model on a model display interface. The hip joint model includes the acetabulum. In response to the operation of placing the acetabular cup model into the acetabular fossa, the acetabular wall thickness information is displayed in a first form in the polar coordinate image of the acetabular wall thickness display interface. The acetabular wall thickness information refers to the thickness information of the acetabular wall at the position of the acetabular cup model after the simulated acetabular cup model is placed into the acetabular fossa. In this embodiment, after the acetabular cup model is placed into the acetabular fossa, the acetabular wall thickness information at the position of the acetabular cup model can be displayed in the polar coordinate graph of the acetabular wall thickness display interface, thereby allowing a comprehensive view of the acetabular wall thickness information, i.e., the remaining bone volume information of the acetabular wall, after the acetabular cup model is placed into the acetabular fossa.

[0059] In one embodiment, the polar radius of the polar coordinate graph represents the elevation angle of the acetabular cup model, the polar angle of the polar coordinate graph represents the orientation of the acetabular cup model, and the origin of the polar coordinate graph represents the rotation center of the acetabular fossa.

[0060] The origin of the polar coordinate graph is the center of rotation of the acetabulum; the polar diameter in the polar coordinate graph is used to characterize the elevation angle of the acetabular cup model, with different polar diameters representing different elevation angles; the polar angle in the polar coordinate graph is used to characterize the orientation of the acetabular cup model, specifically the clock direction, with different polar angles representing different clock directions. In other words, the polar coordinate graph can display the acetabular wall thickness information corresponding to the acetabular fossa at different elevation angles and different clock directions.

[0061] In an optional embodiment, the correspondence between the mortar cup model and the polar coordinate diagram is as follows: Figure 4As shown, the elevation angle of the acetabular cup model corresponds to circles of different radii in the polar coordinate graph, which in turn correspond to the polar diameter in the polar coordinate graph. Taking the slit plane containing the acetabulum as the horizontal plane, the elevation angle of the acetabular cup model refers to the angle between the acetabular cup model and the horizontal plane, with a range of [0°, 90°]. The clock direction of the acetabular cup corresponds to different clock points in the polar coordinate image, i.e., the polar angle in the polar coordinate image. Different polar angles in the polar coordinate graph represent different clock directions around the acetabulum, i.e., the line of sight is perpendicular to the slit plane of the acetabulum. The point directly above it is fixed as 0, and the number of points increases clockwise, with a range of [0, 12]. The accuracy of the elevation angle is 1°, and the accuracy of the clock point (direction) is 0.5 points. The relationship between the top view of the acetabular cup model and the clock point is as follows: Figure 5 As shown.

[0062] In one embodiment, after the user places the acetabular cup model into the acetabular fossa, the orientation and / or size of the acetabular cup model can be adjusted to ensure that the acetabular wall thickness information corresponding to the acetabular fossa meets the requirements. For this purpose, as follows... Figure 6 As shown, the steps of the preoperative planning visualization method for hip joint surgery also include:

[0063] Step 600: In response to the operation of placing the acetabular cup model into the acetabular fossa, display the acetabular cup adjustment controls on the model display interface.

[0064] When a user places the acetabular cup model into the acetabular fossa, the computer device responds to this operation by displaying the acetabular wall thickness information in a polar coordinate graph on the acetabular wall thickness display interface, and also by displaying a floating acetabular cup adjustment control on the model display interface. The acetabular cup adjustment control is used to adjust the position and / or size of the acetabular cup model placed in the acetabular fossa. This embodiment does not limit the display method or position of the acetabular cup adjustment control, as long as its function is achieved.

[0065] Step 610: In response to the trigger operation of the mortis adjustment control, adjust the mortis model.

[0066] On the model display interface, the user triggers an operation on the mortar and cup adjustment controls. The computer device responds to this trigger operation by adjusting the mortar and cup model. The trigger operation can be a click, an input operation, or a drag operation; this embodiment does not limit the trigger operation. The adjustment of the mortar and cup model can be either adjusting its position or its size.

[0067] In this embodiment, in response to the operation of placing the acetabular cup model into the acetabular fossa, an acetabular cup adjustment control can also be displayed on the model display interface. By operating the acetabular cup adjustment control, the acetabular cup model can be adjusted. This facilitates rapid adjustment of the acetabular cup model, allowing observation of acetabular cup models of different sizes or acetabular wall thickness information at different positions of the acetabular cup model in the acetabular fossa through the acetabular wall thickness display interface, thus making the preoperative planning and display method for hip joint surgery more practical.

[0068] The acetabular cup adjustment controls may include acetabular cup position adjustment controls or acetabular cup size adjustment controls. The acetabular cup position adjustment controls are used to adjust the placement position of the acetabular cup model in the acetabular fossa, and the acetabular cup size adjustment controls are used to adjust the size of the acetabular cup model placed in the acetabular fossa.

[0069] In one embodiment, where the acetabular cup adjustment control includes an acetabular cup position adjustment control, such as Figure 7 As shown, this relates to an implementation of adjusting a mortis model in response to a trigger operation on a mortis adjustment control. This implementation includes:

[0070] Step 700: In response to the trigger operation of the mortis cup position adjustment control, adjust the position of the mortis cup model.

[0071] In the model display interface, the user triggers the mortar and cup position adjustment control, and the computer device responds to the trigger by adjusting the position of the mortar and cup model. This trigger can be a click or a slide. Different settings for the mortar and cup position adjustment control result in different trigger operations; this embodiment does not impose any restrictions as long as the functionality is achieved. The user can adjust the position of the mortar and cup model by moving it or rotating it, for example, moving it up, down, left, right, rotating it clockwise, or rotating it counterclockwise at least one of these methods.

[0072] Please continue reading Figure 7 In one embodiment, where the acetabular cup adjustment control includes an acetabular cup size adjustment control, another implementation involves adjusting the acetabular cup model in response to a triggering operation on the acetabular cup adjustment control, the implementation including:

[0073] Step 710: In response to the trigger operation of the mortis cup size adjustment control, adjust the size of the mortis cup model.

[0074] On the model display interface, the user triggers the mortar size adjustment control, and the computer device responds to the trigger by adjusting the size of the mortar model. This trigger can be a click or an input operation. Different settings for the mortar size adjustment control result in different trigger operations; this embodiment does not impose any restrictions, as long as the functionality is achieved. The user can adjust the size of the mortar model by increasing its size, decreasing its size, or adjusting its shape.

[0075] In this embodiment, the acetabular cup adjustment control may include an acetabular cup position adjustment control and an acetabular cup size adjustment control, which enables the adjustment of the position and / or size of the acetabular cup model, thereby improving the practicality of the preoperative planning and display method for hip joint surgery.

[0076] In an optional embodiment, the mortising cup adjustment control is as follows: Figure 8 As shown, the mortar and cup adjustment controls are displayed in a ring. The ring includes arrows representing upward, downward, left, and right directions, as well as a rotation arrow. An input box is displayed above the ring. When the user clicks the upward arrow, the computer moves the mortar and cup model upwards; when the user clicks the left arrow, the computer moves the model to the left; and when the user drags the rotation arrow clockwise, the computer rotates the model clockwise. The user inputs target parameters into the input box, and the computer adjusts the size of the mortar and cup model accordingly; the target parameters are the adjusted size of the mortar and cup model. Figure 8 The target parameter entered in the input box is 48.0 mm. That is, the diameter of the adjusted mortar cup model is 48.0 mm. In this embodiment, the user can use the up, down, left, and right arrows on the computer device's keyboard to adjust the arrows pointing upwards, downwards, left, and right. Figure 8 The shaded area represents the acetabular cup model, and 18.3 indicates that the thickness of the acetabular wall at this location is 18.3 mm.

[0077] In another alternative embodiment, the mortar adjustment control can be a rectangular display control including up, down, left, and right arrows, and size adjustment marks displayed on the mortar model. When a user clicks the up arrow on the rectangular display control, the computer device responds by moving the mortar model upwards; when the user drags the size adjustment marks, the computer responds by determining the size of the mortar model after dragging.

[0078] In one embodiment, the acetabular wall thickness display interface includes a target thickness information display area, which is used to display the target position corresponding to the acetabular cup model and the thickness information at the target position.

[0079] In the acetabular wall thickness display interface, the area in the polar coordinate graph that displays the acetabular wall thickness information corresponding to the acetabular fossa in the first form is the thickness information display area. The acetabular wall thickness display interface may also include a target thickness information display area, which is used to display the target position of the acetabular cup model, that is, the elevation angle and clock direction of the acetabular cup model, as well as the thickness information at the target position, that is, the thickness information of the acetabular wall at the target elevation angle and the target clock direction.

[0080] In an optional embodiment, the acetabular wall thickness display interface is as follows: Figure 9 As shown, Figure 9 The upper-middle area displays the target thickness information, while the lower area displays the thickness information of the acetabular wall in polar coordinates. The orientation in the target thickness information display area is set to the 0 o'clock direction (0o'oclock) and the elevation angle to 0°. The thickness is 18.3 mm, indicating that the thickness of the acetabular wall at the 0 o'clock direction and 0° elevation angle of the acetabular cup model is 18.3 mm.

[0081] In this embodiment, the acetabular wall thickness display interface includes a target thickness information display area, which displays the target position corresponding to the acetabular cup model and the thickness information at that target position. This allows for a clearer display of the target position of the acetabular cup model and the thickness information at that target position, making the information display method more practical.

[0082] In one embodiment, when the acetabular wall thickness display interface includes both a thickness information display area for displaying polar coordinate graphs and a target thickness information display area, the information display method further includes:

[0083] In response to a trigger operation in the polar coordinate graph, the thickness information corresponding to the target position determined by the trigger operation is displayed in the target thickness information display area.

[0084] When a user performs a trigger operation (click) at a specific point on the polar coordinate graph, the computer device responds by displaying the thickness information corresponding to the trigger location in the target thickness information display area. The trigger location is determined by the trigger operation and is the target position on the polar coordinate graph. In other words, by triggering a target position on the polar coordinate graph, the target thickness information display area will show the orientation and elevation angle of the mortise and tenon model at the triggered target position, as well as the corresponding thickness information.

[0085] In an optional embodiment, the target thickness information display area displays by default the thickness information of the acetabular wall at the 0 o'clock position and 0° elevation angle, as well as the thickness information of the acetabular cup model at the 0 o'clock position and 0° elevation angle. If the user performs a trigger operation in the polar coordinate graph, the azimuth, elevation, and thickness information in the target thickness information display area will be updated. The updated azimuth and elevation angles represent the azimuth and elevation angles of the acetabular cup model at the trigger position corresponding to the trigger operation, and the thickness information of the acetabular wall at the trigger position of the acetabular cup model. For example, as... Figure 10 As shown, when a user clicks on a target location in the polar coordinate graph, the orientation displayed in the target thickness information display area is 90'clock, the elevation angle is 7°, and the thickness information corresponding to this target location is 4.5mm.

[0086] In this embodiment, by triggering an operation in the polar coordinate graph, the thickness information at the target location determined by the triggering operation can be displayed in the target thickness information display area. This facilitates the acquisition of detailed orientation and thickness information at any location in the polar coordinate graph, making the preoperative planning display method for hip joint more practical.

[0087] In one embodiment, such as Figure 9 As shown, the acetabular wall thickness display interface also includes parameter control controls (i.e., control controls following the parameters). When the acetabular wall thickness display interface includes parameter control controls, the steps of this information display method further include:

[0088] In response to a trigger operation of the parameter control control, the thickness information at the preset position is displayed in a second form on the polar coordinate graph.

[0089] On the acetabular wall thickness display interface, the user triggers the parameter control controls, and the computer device responds to the triggering operation by displaying the thickness information at the preset position in a second form on the polar coordinate graph.

[0090] The triggering action can be a click or a drag-and-drop action. Users can turn the parameter control controls on or off by triggering them. The parameter control controls are off by default, such as... Figure 9 As shown, the small circular control in the parameter control is located on the left side of the parameter control. The user clicks or drags the small circular control to move it to the right side of the parameter control, thus turning the parameter control on.

[0091] The preset position can be a specific location on the polar coordinate graph pre-set by the user. This embodiment does not limit the preset position, as long as it can achieve its function. The second form can be text or number. That is, the computer device responds to the trigger operation of the parameter control control, causing the parameter control control to be in the open state, and displays the thickness information of the preset position in the polar coordinate graph in the form of text (or numbers). Figure 11 As shown, the small circular control in the parameter control control is located on the right side of the parameter control control. At this time, the parameter control control is in the open state, and the thickness value corresponding to the preset position is displayed at the preset position in the polar coordinate graph, that is, the thickness information is displayed in numerical form. Figure 10 The preset positions include the 0 o'clock position, at different elevation angles (0°, 30°, 60° and 90°), the 3 o'clock position, at different elevation angles (0°, 30°, 60° and 90°), the 6 o'clock position, at different elevation angles (0°, 30°, 60° and 90°), and the 6 o'clock and 9 o'clock positions, at different elevation angles (0°, 30°, 60° and 90°).

[0092] In an optional embodiment, the color of the thickness information displayed numerically in the polar coordinate graph can correspond to a color range set in the polar coordinate graph.

[0093] Please see Figure 12 One embodiment of this application provides a method for preoperative planning and display of hip joint surgery, the method comprising the following steps:
