[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The serial numbers assigned to the components in this application, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning.

[0045] First, before specifically introducing the technical solutions of the disclosed embodiments of the present application, the background technology or technical evolution context on which the embodiments of the present application are based is introduced. With the development of medical technology, hip replacement, as a surgery to replace damaged hip joints with artificial acetabulum and artificial femoral head, is more and more widely used. Before hip replacement, preoperative planning is required, that is, preoperative simulation of the process of placing the acetabular prosthesis and femoral head prosthesis to be replaced in the hip joint. In the process of preoperative planning, when simulating the placement of the acetabular cup in the acetabular fossa, it is necessary to observe the remaining bone mass information of the acetabular wall corresponding to the acetabular fossa, that is, the thickness information of the acetabular wall. In other words, when the acetabular cup is placed 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 mass of the acetabular wall after milling. In traditional technology, the thickness information of the acetabular wall is usually measured by measuring the graphic element, or by measuring with an actual measuring tool to obtain the thickness information of the acetabular wall. However, the conventional method for determining the thickness information of the acetabular wall requires rotating the hip joint model when determining the thickness information of the acetabular wall in different directions, and cannot realize the overall observation of the thickness information of the acetabular wall in various directions. In view of this, the present application provides a hip joint preoperative planning display method.

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

[0047] The hip joint preoperative planning display method provided in the embodiment of the present application can be applied to a computer device, which can be, but is not limited to, an industrial computer, a laptop computer, and a tablet computer. Figure 1 As shown. The computer device includes a processor, a memory, a communication interface, a display screen and an input device connected through a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, a mobile cellular network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a hip joint preoperative planning display method is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covering the display screen, or a button, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse, etc.

[0048] In one embodiment, Figure 2 As shown, a hip joint preoperative planning display method is provided. This embodiment uses the method applied to a computer device as an example. 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 display interface of the computer device includes a model display interface, and the model display interface is used to display the hip joint model. The hip joint model can be obtained by a medical scanning device and transmitted to the computer device. The medical scanning device can be a computer X-ray tomography device, or a nuclear magnetic resonance scanning device, etc. After the medical scanning device scans and obtains the hip joint model, it transmits the hip joint model to the computer device, and the computer device displays the joint model on the model display interface. The hip joint model includes an acetabulum, and the acetabulum is used to place the acetabular cup model.

[0051] Step 210, in response to the operation of placing the acetabular cup model into the acetabular socket, displaying acetabular wall thickness information in a first form in the polar coordinate diagram 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 acetabular cup model is simulated to be placed into the acetabular socket.

[0052] The acetabular cup model can be pre-set by the user and stored in the computer device. In the model display interface, the user obtains the acetabular cup model and moves the acetabular cup model to the acetabulum. This embodiment does not limit the specific method for the user to obtain the acetabular cup model.

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

[0054] The display interface of the computer device also includes an acetabular wall thickness display interface, and a polar coordinate diagram is displayed on the acetabular wall thickness display interface. The computer device responds to the operation that the acetabular cup model is placed (moved to) the acetabular fossa by the user, and displays the acetabular wall thickness information with the first form in the polar coordinate diagram of the acetabular wall thickness display interface. In other words, after the computer device simulates the acetabular cup model being placed in the acetabular fossa, the acetabular wall of the acetabular fossa and the acetabular cup model interfere with the region, i.e. the acetabular wall, which overlaps with the acetabular cup model, is milled so that the acetabular cup model is placed in the acetabular fossa completely. The thickness information of the acetabular wall after milling is exactly the information displayed in the polar coordinate diagram of the acetabular wall thickness display interface. The first form can be different colors, or different labels, i.e. different acetabular wall thickness information is represented by different colors or different labels. The present embodiment does not limit the first form, as long as different acetabular wall thickness information can be distinguished.

[0055] In an optional embodiment, in the initial state, the acetabular wall thickness display interface and the model display interface can be simultaneously displayed on the interface of the computer device, and when the acetabular cup model is not placed in the acetabular fossa, the polar coordinate diagram in the acetabular wall thickness display interface is empty, or displays the last 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 diagram of the acetabular wall thickness display interface.

[0056] In another optional embodiment, in the initial state, the acetabular wall thickness display interface and the model display interface are not displayed on the interface of the computer device at the same time, that is, only the model display interface is displayed on the interface of the computer device in the initial state. The computer device displays the acetabular wall thickness display interface in response to the user's operation of inserting the acetabular cup model into the acetabular fossa, and simultaneously displays the acetabular wall thickness information in the polar coordinate diagram in the acetabular wall thickness display interface in the first form. The acetabular wall thickness display interface can be suspended on the acetabular wall thickness display interface, and the acetabular wall thickness display interface can 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, namely 0-2 mm, 2-5 mm and greater than 5 mm. These three intervals are determined by different colors in the polar coordinate image.

[0058] The hip joint preoperative planning display method provided in this embodiment displays a hip joint model in a model display interface; the hip joint model includes an acetabular fossa; in response to the operation of inserting 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 acetabular cup model is simulated to be inserted into the acetabular fossa. In this embodiment, after the acetabular cup model is inserted into the acetabular fossa, the acetabular wall thickness information at the position of the acetabular cup model can be displayed in the polar coordinate diagram in the acetabular wall thickness display interface, so that the acetabular wall thickness information after the acetabular cup model is inserted into the acetabular fossa, that is, the acetabular wall remaining bone mass information, can be viewed as a whole.

[0059] In one embodiment, the polar diameter 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 socket.

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

[0061] In an optional embodiment, the corresponding relationship between the acetabular 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 diagram, and corresponds to the polar diameter in the polar coordinate diagram; taking the section where the acetabulum is located 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, and the range of the elevation angle is [0°, 90°]. The clock direction of the acetabular cup corresponds to different clock points in the polar coordinate image, that is, the polar angle in the polar coordinate image. Different polar angles in the polar coordinate diagram represent different clock directions around the acetabular fossa, that is, the line of sight is perpendicular to the direction of the acetabular fossa section, and the top is fixed as 0 point. The number of points increases clockwise, and the range of the clock points is [0, 12] points. The accuracy of the elevation angle is 1°, and the accuracy of the clock points (direction) is 0.5 points. The relationship between the top view of the acetabular cup model and the clock points is shown in the figure. Figure 5 shown.

[0062] In one embodiment, after the user places the acetabular cup model into the acetabular socket, in order to ensure that the acetabular wall thickness information corresponding to the acetabular socket meets the requirements, the user can adjust the direction and / or size of the acetabular cup model. Figure 6 As shown, the steps of the hip joint preoperative planning display method also include:

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

[0064] When the user performs the operation of placing the acetabular cup model into the acetabular fossa, the computer device can not only display the acetabular wall thickness information in the polar coordinate diagram on the acetabular wall thickness display interface in response to the operation, but also can suspend and display the 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 mode and display position of the acetabular cup adjustment control, as long as its function can be achieved.

[0065] Step 610: In response to a trigger operation on the acetabular cup adjustment control, adjust the acetabular cup model.

[0066] On the model display interface, the user triggers the acetabular cup adjustment control, and the computer device adjusts the acetabular cup model in response to the trigger operation. The trigger operation can be a click operation, an input operation, or a drag operation, and this embodiment does not limit the trigger operation. The adjustment of the acetabular cup model can be an adjustment of the position of the acetabular cup model, or an adjustment of the size of the acetabular cup model.

[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, and the acetabular cup model can be adjusted by operating the acetabular cup adjustment control. This facilitates the rapid adjustment of the acetabular cup model, so that acetabular cup models of different sizes or acetabular wall thickness information of the acetabular cup model at different positions in the acetabular fossa can be observed through the acetabular wall thickness display interface, making the hip joint preoperative planning display method more practical.

[0068] The acetabular cup adjustment control may include an acetabular cup position adjustment control and an acetabular cup size adjustment control. The acetabular cup position adjustment control is used to adjust the placement position of the acetabular cup model in the acetabular socket, and the acetabular cup size adjustment control is used to adjust the size of the acetabular cup model placed in the acetabular socket.

[0069] In one embodiment, where the cup adjustment control includes a cup position adjustment control, such as Figure 7 As shown, it is related to an implementation method of adjusting the acetabular cup model in response to a triggering operation of the acetabular cup adjustment control, and the implementation method includes:

[0070] Step 700: In response to a trigger operation on an acetabular cup position adjustment control, the position of the acetabular cup model is adjusted.

[0071] In the model display interface, the user triggers the acetabular cup position adjustment control, and the computer device adjusts the position of the acetabular cup model in response to the trigger operation. The trigger operation can be a click operation or a slide operation. The setting mode of the acetabular cup position adjustment control is different, and the corresponding trigger operation is also different. This embodiment is not limited to this, as long as its function can be achieved. The user can move or rotate the position of the acetabular cup model, for example, at least one of moving the acetabular cup model upward, downward, left, right, rotating clockwise and counterclockwise.

[0072] Please continue to see Figure 7 In one embodiment, when the acetabular cup adjustment control includes an acetabular cup size adjustment control; another implementation method of adjusting the acetabular cup model in response to a triggering operation on the acetabular cup adjustment control includes:

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

[0074] In the model display interface, the user triggers the acetabular cup size adjustment control, and the computer device adjusts the size of the acetabular cup model in response to the trigger operation. The trigger operation can be a click operation or an input operation. The setting mode of the acetabular cup size adjustment control is different, and the corresponding trigger operation is also different. This embodiment does not limit this, as long as its function can be achieved. The user can adjust the size of the acetabular cup model by increasing the size of the acetabular cup model, reducing the size of the acetabular cup model, or adjusting the shape of the acetabular cup model.

[0075] In this embodiment, the acetabular cup adjustment control may include an acetabular cup position adjustment control and may also include an acetabular cup size adjustment control, so that the position and / or size of the acetabular cup model can be adjusted, thereby improving the practicality of the hip joint preoperative planning display method.

[0076] In an optional embodiment, the acetabular cup adjustment control is as follows: Figure 8 As shown, the acetabular cup adjustment control is displayed in the form of a ring, and the ring includes arrows representing the upward direction, the downward direction, the left direction, and the right direction, as well as the rotation arrow, and an input box is also displayed above the ring. The user clicks the upper arrow in the ring, and the computer device responds to the click operation to move the acetabular cup model upward; the user clicks the left arrow in the ring, and the computer device responds to the click operation to move the acetabular cup model to the left; the user drags the rotation arrow in the ring clockwise, and the computer device responds to the click operation to rotate the acetabular cup model clockwise. The user enters the target parameter in the input box, and the computer device responds to the input operation to adjust the size of the acetabular cup model; the target parameter is the size of the adjusted acetabular cup model. Figure 8 The target parameter entered in the input box is 48.0 mm. That is, the diameter of the acetabular cup model after adjustment is 48.0 mm. In this embodiment, the user can adjust the arrows pointing up, down, left and right in the circle through the up, down, left and right buttons on the keyboard of the computer device. Figure 8 The middle shaded area is the acetabular cup model, and 18.3 indicates that the thickness of the acetabular wall at this position is 18.3 mm.

[0077] In another optional embodiment, the acetabular cup adjustment control may be a rectangular display control, which includes up, down, left and right arrows, and a size adjustment mark displayed on the acetabular cup model. The user clicks the up arrow on the rectangular display control, and the computer device moves the acetabular cup model upward in response to the click operation; the user drags the size adjustment mark, and the computer device determines the size of the acetabular cup model after the dragging in response to the dragging operation.

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

[0079] The area of ​​the acetabular wall thickness display interface that displays the acetabular wall thickness information corresponding to the acetabular fossa in the polar coordinate diagram in the first form is the thickness information display area. The acetabular wall thickness display interface can 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 of the acetabular cup model and the clock direction of the acetabular cup model, and 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: Fig. 9 As shown, Fig. 9 The upper middle area is the target thickness information display area, and the lower area is the thickness information display area where the polar coordinate graph of the acetabular wall thickness information is displayed. The default orientation in the target thickness information display area is 0 o'clock and the elevation angle is 0°, thickness: 18.3mm, indicating that the thickness information of the acetabular wall at the 0 o'clock direction and the elevation angle of 0° of the acetabular cup model is 18.3mm.

[0081] In this embodiment, the acetabular wall thickness display interface includes a target thickness information display area, in which the target position corresponding to the acetabular cup model and the thickness information at the target position can be displayed. In this way, the target position of the acetabular cup model and the thickness information at the target position can be displayed more clearly, 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 a polar coordinate graph 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, thickness information corresponding to a target position determined by the trigger operation is displayed in a target thickness information display area.

[0084] The user performs a trigger operation, i.e., a click operation, at a certain location in the polar coordinate diagram, and the computer device responds to the trigger operation by displaying the thickness information corresponding to the trigger location in the target thickness information display area. The trigger location is the target location in the polar coordinate diagram determined by the trigger operation. In other words, when the user performs a trigger operation on the target location in the polar coordinate diagram, the target thickness information display area will display the orientation and elevation of the acetabular cup model at the target location triggered by the user, and will display the thickness information corresponding to the target location.

[0085] In an optional embodiment, the target thickness information display area displays the acetabular wall thickness information at 0 o'clock and an elevation of 0° by default, and the acetabular cup model is at 0 o'clock and an elevation of 0°. 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 are the azimuth and elevation of the acetabular cup model at the trigger position corresponding to the trigger operation, and the acetabular wall thickness information when the acetabular cup model is at the trigger position. For example, Fig.10 As shown, the user clicks on the target position in the polar coordinate diagram, and the azimuth displayed in the target thickness information display area is 9 o'clock and the elevation angle is 7°. The thickness information corresponding to the target position is 4.5 mm.

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

[0087] In one embodiment, Fig. 9 As shown, the acetabular wall thickness display interface also includes a parameter control control (i.e., a control control after the parameter). In the case where the acetabular wall thickness display interface includes a parameter control control, the steps of the information display method also include:

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

[0089] In the acetabular wall thickness display interface, the user triggers the parameter control widget, and the computer device responds to the trigger operation to display the thickness information of the preset position in the polar coordinate graph in a second form.

[0090] The trigger operation can be a click operation or a drag operation. The user can turn the parameter control on or off by triggering the parameter control. The parameter control is in the off state by default. Fig. 9 As shown, the small circular control in the parameter control control is on the left side of the parameter control control. The user clicks or drags the small circular control to move the small circular control to the right side of the parameter control control, so that the parameter control control is in the on state.

[0091] The preset position may be a specific position in the polar coordinate diagram pre-set by the user. This embodiment does not limit the preset position as long as its function can be achieved. The second form may be in text form or in digital form. That is, the computer device responds to the triggering operation of the parameter control control so that the parameter control control is in the on state and displays the thickness information of the preset position in the polar coordinate diagram in the form of text (or numbers) at the preset position. Fig.11 As shown, the small circular control in the parameter control is on the right side of the parameter control. At this time, the parameter control is in the on 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 digital form. Fig.10 The preset positions in the include 0 o'clock direction at different elevations (0°, 30°, 60° and 90°), 3 o'clock direction at different elevations (0°, 30°, 60° and 90°), 6 o'clock direction, 6 o'clock direction at different elevations (0°, 30°, 60° and 90°), 6 o'clock direction and 9 o'clock direction at different elevations (0°, 30°, 60° and 90°).

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