Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
Fig. 1 is a schematic view of a radiological abduction angle and a radiological anteversion angle, for an hip prosthesis, as shown in fig. 1, the radiological abduction angle (Radiographic Inclination, abbreviated as RI) being the angle between the projection of the acetabular cup axis onto the coronal plane of the body and the long axis of the body, the radiological anteversion angle (Radiographic Anteversion, abbreviated as RA) being the angle between the acetabular cup axis and the coronal plane of the body, i.e. the angle between the acetabular cup axis and the projection of the acetabular cup axis onto the coronal plane of the body, in fig. 1, ON being the acetabular cup axis, ON' being the projection of ON onto the coronal plane of the body.
Fig. 2 is an interactive schematic diagram of adjusting an installation angle of a hip joint prosthesis model in the prior art, as shown in fig. 2, the installation angle includes a rake angle and an abduction angle, the adjustment of the rake angle and the abduction angle is mainly achieved by directly inputting an angle value into an interactive interface by a user, a system can calculate an installation direction of the hip joint prosthesis model according to the input angle value, and then the user observes the installation direction of the hip joint prosthesis model in Volume Rendering (VR) and Multi-planar reconstruction (MPR) of image processing software, and determines whether the adjustment of the angle value is required based on the installation direction to determine a final installation angle. On one hand, manual input is required for such adjustment, which is relatively complicated; on the other hand, once the user inputs an error, meaningless adjustments are made. In summary, the installation angle adjustment method of the hip joint prosthesis model in the prior art has lower adjustment efficiency.
In one embodiment, as shown in fig. 3, a method for adjusting the installation angle of a hip joint prosthesis model is provided, and this embodiment is exemplified by applying the method to a terminal, it will be understood that the method may also be applied to a server, and may also be applied to a system including the terminal and the server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step S302, determining the value of the installation angle of the hip joint prosthesis model in response to the selection instruction within the target adjustment range displayed in the interactive interface, wherein the target adjustment range can limit the value of the installation angle.
In this embodiment, the selection instruction applied to the interactive interface may be a finger selection operation performed by the user in the interactive interface, or may be a touch operation implemented by movement of a touch pen, where the screen used is a touch screen. Alternatively, the user may also input selection instructions through input means, such as a keyboard and a mouse.
Because the target adjustment range can limit the value of the installation angle, the user can only adjust the installation angle within a limited range in the adjustment process, thereby improving the adjustment efficiency of the installation angle.
Step S304, according to the value of the installation angle, the installation result of the hip joint prosthesis model on the hip joint model is displayed in the interactive interface.
The hip joint model is a virtual model obtained by performing simulation reconstruction on a real hip joint of a target object, and is different from the hip joint prosthesis model. After receiving the selection instruction of the installation angle, the installation position of the hip joint prosthesis model on the hip joint model can be determined according to the value of the installation angle, wherein the hip joint model is obtained by modeling according to the actual hip joint size and morphological parameters of the target object.
After the installation position of the acetabular cup is determined, the installation result of the hip joint prosthesis model can be displayed on the interactive interface, specifically, the installation position of the hip joint prosthesis model on the hip joint model, the distance and the angle relation between the hip joint prosthesis model and the hip joint model are visualized by displaying the hip joint prosthesis model and the three-dimensional hip joint model.
Through the steps S302 and S304, the present embodiment displays the value of the installation angle of the hip-joint prosthesis model through the visualized target adjustment range, and displays the installation result of the hip-joint prosthesis model on the hip-joint model, so as to realize the visualization of the installation process of the hip-joint prosthesis model, so that the user can more intuitively observe the installation condition of the hip-joint prosthesis model, purposefully perform the next adjustment, and meanwhile, the visualized target adjustment range itself has a limitation on the installation angle, so that the number of repeated operations can be reduced, the problem that the user needs repeated operations for determining the final installation angle in the prior art, which results in higher labor cost and lower efficiency, is solved, the installation efficiency of the hip-joint prosthesis model is improved, and finally, the front-end interface interaction method for performing the simulation adjustment of the installation angle of the hip-joint prosthesis model in the safety range is realized.
In one embodiment, the target adjustment range needs to be determined in advance before adjusting the installation angle of the hip prosthesis model in the interactive interface. Specifically, the installation angle includes a rake angle and a abduction angle, first, a first adjustment section of the rake angle and a second adjustment section of the abduction angle are determined based on physiological definitions of the rake angle and the abduction angle, and then, a target adjustment range is constructed and displayed in the interactive interface based on the first adjustment section and the second adjustment section.
Preferably, based on the first adjustment interval and the second adjustment interval, constructing the target adjustment range specifically includes: a plane rectangular coordinate system is established by taking the forward inclination angle as a first coordinate axis and the abduction angle as a second coordinate axis; determining a first coordinate range of the first coordinate axis based on the first adjustment interval, and determining a second coordinate range of the second coordinate axis based on the second adjustment interval; a target adjustment range in the planar rectangular coordinate system is determined based on the first coordinate range and the second coordinate range.
In the embodiment, the range of values of the front inclination angle and the abduction angle is corresponding to the plane rectangular coordinate system, so that the visual degree of the installation angle adjusting process is further improved.
Preferably, the visualized target adjustment range can also display the constraint relation between the installation angles, for example, after one installation angle is determined, the values of other installation angles can be adjusted only in the corresponding range. The constraint relation can be preset according to the safety movement range which the target object wants to reach, or can be set according to the constraint relation among the general installation angles. The selection instruction is the value of each installation angle input by a user or calculated by the processor.
Thus, in some of these embodiments, the target adjustment range may also be determined as follows. Likewise, the installation angle of the hip joint prosthesis model comprises a pre-tilt angle and an abduction angle, and a first adjustment interval of the pre-tilt angle, a second adjustment interval of the abduction angle and an association relation between the pre-tilt angle and the abduction angle are determined; and constructing a target adjustment range based on the first adjustment interval, the second adjustment interval and the association relation, and displaying the target adjustment range on the interactive interface. As shown in fig. 4, a schematic view of the installation of the hip prosthesis model is provided, in which the positions of the acetabular cup 41, the ball head 42 and the femoral stem 43 need to be taken into account. In this embodiment, first, the installation system of the hip joint prosthesis model with the interactive interface can calculate the adjustable angle range meeting the requirement of the safety range of motion according to the relationship between the pre-tilt angle and the abduction angle, i.e. the association relationship. Specifically, the anteversion angle and the abduction angle of the acetabular cup are mutually restricted, and the hip joint prosthesis model is placed in a safe angle range to obtain the optimal matching between the inclusion of the acetabular cup on the femoral head and the physiological safe movement range. Secondly, the user can select and adjust the combination of the values of the anteversion angle and the abduction angle in a safe angle range, and the system can calculate and draw the installation direction of the hip joint prosthesis model on the image three-dimensional image according to the values of the anteversion angle and the abduction angle. Finally, the user can more quickly and efficiently find the optimal placement direction of the acetabular shaft of the hip joint prosthesis model by observing the installation direction of the hip joint prosthesis model, thereby completing preoperative planning and improving the working efficiency.
Preferably, the process of constructing the target adjustment range is as follows: the front dip angle is used as a first coordinate axis, the abduction angle is used as a second coordinate axis, and a plane rectangular coordinate system is established; determining a first coordinate range of the first coordinate axis based on the first adjustment interval, and determining a second coordinate range of the second coordinate axis based on the second adjustment interval; determining a candidate adjustment range in a plane rectangular coordinate system based on the first coordinate range and the second coordinate range; and determining a target adjustment range in the candidate adjustment ranges based on the association relation. Fig. 5 is a schematic view of a target adjustment range of the pretilt angle and a target adjustment range of the abduction angle, as shown in fig. 5, an adjustment region of the pretilt angle (RA) is set as coordinates on the X axis, an adjustment region of the abduction angle is set as coordinates on the Y axis, and then a coordinate grid is drawn based on the X axis and the Y axis.
Further, after determining the candidate adjustment range in the rectangular planar coordinate system, the forbidden adjustment range needs to be divided, which specifically includes: and determining a forbidden adjustment range in the candidate adjustment ranges based on the association relation, and displaying the forbidden adjustment range. Specifically, an unselected area of the rake angle and the abduction angle determined by the association relationship may be used as an adjustment prohibition range, and the adjustment prohibition range is an area incapable of responding to the selection instruction. The adjustment of the forward dip angle and the abduction angle can be more intuitively assisted by setting the forbidden adjustment range in the plane rectangular coordinate system, and the working efficiency is improved.
Preferably, the prohibited adjustment range needs to be filled to distinguish the prohibited adjustment range from the target adjustment range. Specifically, the forbidden adjustment range can be filled in by a legend, or can be distinguished by a color block.
In this embodiment, the adjustment interval of RA is-30 ° to 150 °, and the adjustment interval of RI is-30 ° to 90 °, but is limited by the association relationship, and there are some non-selectable forbidden adjustment ranges in the rectangular plane coordinate system, so as toThe method indicates that the area outside the forbidden adjustment range is the target adjustment range, the user can only give a selection instruction within the target adjustment range, and one selection instruction can select a proper combination of the front dip angle and the abduction angle, for example, the method is performed by +.>The response to the selection command is shown, and further, the selection command corresponding to the flag in this embodiment is determined to be RA 22 ° and RI 38 ° may be displayed in a different color. Selectable angle combinations within the target adjustment range are possible, and the basic activities of the target object can be satisfied after operation. Correspondingly, the system with the interactive interface only responds to the selection instruction in the target adjustment range, and then the installation direction of the hip joint prosthesis model is determined according to the selected combination, so that a user can observe the installation result of the hip joint prosthesis model, and the situation of the hip joint movement of the target object after installation can be judged.
It should be noted that, any value may be arbitrarily input into the rake angle and the abduction angle in fig. 2, and the angle combinations in the forbidden adjustment range in fig. 5 do not satisfy the constraint relation, whereas the angle combinations in the target adjustment range satisfy the constraint relation, so that the rake angle and the abduction angle can only be selected in the target adjustment range during the operation planning. Based on the above, the method is faster than the prior art in the process of searching the placement angle of the optimal hip joint prosthesis model.
In some of these embodiments, determining the value of the installation angle of the hip prosthesis model in response to the selection instruction comprises: determining coordinate values of corresponding coordinate points in a target adjustment range based on the selection instruction; and determining the value of the installation angle based on the coordinate values. Therefore, in the using process, the user can directly determine the values of the two installation angles through one-time selection action, and the planning efficiency is greatly improved.
In some embodiments, after displaying the installation result of the hip joint prosthesis model on the hip joint model according to the value of the installation angle, the user may also adjust the value of the installation angle a plurality of times according to the installation result. Specifically, after the installation result in the interactive interface is seen, if the user is not satisfied with the installation result of the current hip joint prosthesis model, a selection instruction can be input again in the target adjustment range, the interactive interface responds to the selection instruction in the target adjustment range to obtain the value after the installation angle is updated, and then the installation result after the hip joint prosthesis model is updated is displayed according to the value after the installation angle is updated until the hip joint safety movement range corresponding to the installation result meets the preset hip joint safety movement condition. In each adjustment process, the installation result between the current hip joint prosthesis model and the hip joint three-dimensional model can be displayed in the interactive interface, so that a user can conveniently adjust the installation position of the hip joint prosthesis model according to the requirement.
In some of these embodiments, prior to determining the value of the installation angle of the hip-joint prosthesis model, morphological parameters of the hip-joint prosthesis model need to be initially confirmed through an interactive interface. Firstly, displaying a section image of a hip joint on an interactive interface, and acquiring marking points of the hip joint in the section image, wherein the section image of the hip joint is a transverse section, a coronal section and a sagittal section of the hip joint obtained by an MPR technology, and the marking points are marks which are contained in the hip joint and can represent the shape and the anatomical information of the hip joint and are used for registering between a hip joint prosthesis model and a hip joint model. Because the depth information of the marking points can be more accurately obtained on each section, each marking point is determined in the section image of the interactive interface in the embodiment. Then, the morphological parameters of the hip joint are determined according to the marking points of the hip joint, and specifically, the morphological parameters are parameters for determining the size, the angle and the like of the hip joint or the hip joint prosthesis model, and can be calculated according to coordinates among the marking points. Finally, the morphological parameters of the hip joint prosthesis model corresponding to the hip joint are determined according to the morphological parameters of the hip joint, so that the matching degree between the hip joint model and the hip joint prosthesis model is improved.
In some of these embodiments, fig. 6 is a flow chart of a method of acquiring a hip joint model, the method comprising the steps of:
step S602, acquiring medical image data of a hip joint.
The medical image data may be obtained by performing medical imaging scan on a hip joint of the target object, for example, an electronic computed tomography (Computed Tomography, abbreviated as CT) image, a positron emission tomography (Positron Emission Computed Tomography, abbreviated as PET) image, and the like.
In step S604, the bone tissue in the medical image data is segmented to obtain a hip mask and a femur mask.
Step S606, a hip joint model is generated based on the hip mask and the femur mask.
Because the complete hip joint is composed of the hip bone and the femur, after the medical image data is obtained, the hip bone mask and the femur mask of the target object are required to be separated in the medical image data, and pathological tissues and tissues needing to be rasped are removed, so that a more accurate three-dimensional model of the hip joint is obtained. Specifically, the three-dimensional model may be implemented by three-dimensional image processing software.
Through the steps S602 to S606, the three-dimensional model of the hip joint is fitted based on the medical image of the target object, so that the three-dimensional model can be more accurate, and the adaptation degree between the hip joint prosthesis model and the three-dimensional model of the hip joint is further improved.
The following describes a method for adjusting the installation position of the hip prosthesis model by means of a preferred embodiment.
