As shown in fig. 1, a schematic flowchart of a method for determining applicability of a nasal prosthesis according to an embodiment of the present application is provided, where the method includes:
s110, acquiring tension of nose skin of a augmentation rhinoplasty object and tension of a nose prosthesis to be implanted into the nose of the augmentation rhinoplasty object.
It is understood that the augmentation rhinoplasty subjects refer to those unspecified individuals who have augmentation rhinoplasty requirements. In general, the amount of tension at each contour point of the nasal skin of a hump nose subject is equal. Thus, the tension of the nasal prosthesis of the nose of the augmentation rhinoplasty object can be measured by using a tool in advance.
In one embodiment of the present application, the obtaining tension of the nasal skin of the augmentation rhinoplasty subject comprises:
firstly, receiving tension values of nose skin of the augmentation rhinoplasty object transmitted by a plurality of tension meters;
secondly, calculating a first average value of the nose skin tension values sent by the tension meters;
finally, the first average value is determined as the tension of the nasal skin of the augmentation rhinoplasty subject.
It can be understood that the method can firstly measure the tension values of the nose augmentation subject at different contour points at the same time, and then calculate the average tension value of the nose skin of the nose augmentation subject; the tension value of one contour point of the hump nose object at different moments can be measured first, and then the tension average value of the nose skin of the hump nose object can be calculated. Of course, the tension values of the nose augmentation subject at different contour points at different moments can also be measured, and then the average tension value of the nose skin of the nose augmentation subject is calculated, which is not particularly limited in the embodiment of the present application.
In one embodiment of the present application, the obtaining tension of the nasal prosthesis to be implanted in the nose of the augmentation nasal subject comprises:
firstly, receiving tension values of the nose prosthesis sent by a plurality of tension meters;
secondly, calculating a second average value of the tension values of the nasal prostheses sent by the tension meters;
finally, the second average value is determined as the tension of the nasal prosthesis to be implanted into the nose of the augmentation nasal subject.
It will be appreciated that specific details may be found in the above description of obtaining tension in the nasal skin of a augmentation nasal subject.
The tension meter can be any type of tension meter, and when in measurement, a measurer can hold the tension meter by hand, press a probe of the tension meter on the surface of the nose prosthesis to be implanted or the surface of the nose skin of the nose augmentation subject, and read the tension value displayed by the tension meter.
S120, acquiring a nose body model and a nose skin model of the augmentation rhinoplasty object.
It can be understood that the nose body model of the augmentation rhinoplasty object is a virtual model corresponding to the tissue below the nose surface skin of the augmentation rhinoplasty object (which may also be simply referred to as the hard tissue of the nose in the embodiment of the present application), and the tension value of each contour point in the nose body model is not changed in the augmentation rhinoplasty simulation process, that is, the nose body model is not deformed in the augmentation rhinoplasty simulation process. The nose skin model is a virtual model corresponding to the nose surface skin of the augmentation rhinoplasty object, and tension values of all contour points in the nose skin model are changed in the augmentation rhinoplasty simulation process, namely the nose skin model is deformed in the augmentation rhinoplasty simulation process.
The nose body model and the nose skin model of the augmentation rhinoplasty object are two sub-models under the same nose model, namely, the nose body model and the nose skin model are combined into the nose model of the augmentation rhinoplasty object.
In one embodiment of the present application, step S120 specifically includes the following steps:
firstly, receiving a target format file generated after a stereoscopic scanner performs stereoscopic scanning on the nose of the augmentation rhinobyon object;
and secondly, analyzing the target format file to generate a nose body model and a nose skin model of the augmentation rhinoplasty object.
It will be appreciated that the stereoscopic scanner may be any type of stereoscopic scanner that a measurer may align with the nose skin of the nasal prosthesis or nasal augmentation subject to be implanted during scanning, thereby generating a target format file. The object format file is generally a standard file format of a three-dimensional image model, and may be, for example, an obj format file. The object format file contains information such as the serial numbers, three-dimensional coordinates and the like of all contour points in the three-dimensional image model.
When the target format file is analyzed, the target format file can be imported into application software such as meshlab and maya which can be used for performing nose augmentation simulation operation, so as to generate a nose body model and a nose skin model of the nose augmentation object.
It should be noted that, the specific process of importing the target format file into the application software that may be used to perform the augmentation-nose simulation operation and generating the nose body model and the nose skin model of the augmentation-nose object may refer to the related art, and the embodiment of the present application is not limited in particular.
S130, obtaining a virtual model of the nose prosthesis.
It can be understood that the virtual model of the nose prosthesis is a virtual model corresponding to the nose prosthesis to be implanted into the nose of the augmentation rhinoplasty object, and the tension value of each contour point in the virtual model of the nose prosthesis is not changed in the augmentation rhinoplasty simulation process, that is, the virtual model of the nose prosthesis is not deformed in the augmentation rhinoplasty simulation process. However, the virtual model of the nose prosthesis, when placed between the nose body model and the nose skin model, may cause a change in the tension value of each contour point in the nose skin model, i.e. the nose skin model may be deformed during the augmentation nose simulation.
In one embodiment of the present application, step S130 specifically includes the following steps:
firstly, receiving a target format file generated after a three-dimensional scanner performs three-dimensional scanning on the nose prosthesis;
And secondly, analyzing the target format file to generate a virtual model of the nose prosthesis.
It will be appreciated that specific details may be found in the above description of obtaining a nasal ontology model and a nasal skin model of the augmentation nasal object.
In another embodiment of the present application, the obtaining a virtual model of the nasal prosthesis includes:
importing virtual model data corresponding to the nasal prosthesis from predetermined three-dimensional modeling software;
reconstructing a virtual model of the nasal prosthesis based on the virtual model data.
The predetermined three-dimensional modeling software may be any existing three-dimensional modeling software such as 3Dmax, CAD, solidWorks, matlab, and the embodiment of the present application is not limited thereto.
And S140, placing the virtual model between the nose body model and the nose skin model to obtain a nose augmentation effect image of the nose augmentation object.
It will be appreciated that in the application software of the augmentation-nose simulation operation, the virtual model may be placed at any position between the nose body model and the nose skin model, so as to obtain an augmentation-nose effect image of the augmentation-nose object. Specifically, in the application software of the augmentation-nose simulation operation, a physical extrusion effect simulation software library engine may be utilized to perform augmentation-nose extrusion effect simulation based on the virtual model, the nose ontology model and the nose skin model and output the simulated effect. The application software of the augmentation-nose simulation operation can acquire indexes such as tension values, deformation coefficients and the like of each contour point of each model in the simulation process in real time, further acquire three-dimensional coordinates of the contour points of each model at each moment, and generate an augmentation-nose effect image of the augmentation-nose object according to the three-dimensional coordinates of the contour points of each model. Therefore, a user can intuitively and clearly observe the shape change condition of each model in the hump nose process.
S150, judging whether the nose prosthesis is suitable for the nose augmentation object according to the tension of the nose skin, the tension of the nose prosthesis and the nose augmentation effect image.
As illustrated in fig. 2, in one embodiment of the present application, S150 may include the following specific steps:
and S210, taking the tension of the nose skin as an initial tension value of each first model contour point in the nose skin model.
It will be appreciated that the acquired tension of the nasal skin of the nasal augmentation subject may be set to an initial tension value for each first model contour point in the nasal skin model. The initial tension value of each first model contour point refers to the mutual traction force of each first model contour point on the contact surface of two adjacent contour points, wherein the mutual traction force exists inside each first model contour point and is perpendicular to the contact surface of the two adjacent contour points before the nose augmentation simulation is performed.
S220, taking the tension of the nose prosthesis as an initial tension value of each second model contour point in the virtual model.
Similarly, the obtained tension of the nasal prosthesis to be implanted into the nose of the augmentation rhinoplasty object may be set as an initial tension value of each second model contour point in the virtual model.
S230, calculating to obtain target tension values of the contour points of the first models and target tension values of the contour points of the second models after the virtual models are placed according to the initial tension values of the contour points of the first models, the initial tension values of the contour points of the second models and deformation parameters generated by the models when the virtual models are placed.
It is understood that the deformation parameters generated by each model when the virtual model is placed refer to the deformation parameters generated by each model when the virtual model is placed between the nose body model and the nose skin model. Under the condition that the initial tension value of each first model contour point, the initial tension value of each second model contour point and deformation parameters generated by each model when the virtual model is placed are known, the target tension value of each first model contour point and the target tension value of each second model contour point after the virtual model is placed can be calculated according to the existing basic principle formulas of pressure and deformation.
S240, combining the target tension value of each first model contour point and the target tension value of each second model contour point to determine whether the nose prosthesis is suitable for the hump nose object.
In one embodiment of the present application, step S240 may include the following specific steps:
if the target tension value of one or more contour points in each first model contour point is greater than a preset first tension threshold value and/or the target tension value of one or more contour points in each second model contour point is greater than a preset second tension threshold value, judging that the nose prosthesis is not suitable for the hump nose object;
and if the target tension value of each first model contour point is smaller than or equal to the first tension threshold value and the target tension value of each second model contour point is smaller than or equal to the second tension threshold value, judging that the nose prosthesis is suitable for the hump nose object.
It will be appreciated that the tension threshold for the first predetermined model contour point is generally less than the tension threshold for the second predetermined model contour point, and that specific values for both tension thresholds may be predetermined by an administrator prior to the start of the augmentation rhinoplasty simulation procedure or determined by other reasonable means. When the target tension value of one or more contour points in each first model contour point is greater than a preset first tension threshold value and/or the target tension value of one or more contour points in each second model contour point is greater than a preset second tension threshold value, the fact that the tension value of one or more contour points in each first model exceeds a maximum bearable tension range or the tension value of one or more contour points in each second model exceeds a maximum bearable tension range causes the model structure fracture of the part of contour points in the model can be judged, and therefore the nose prosthesis is not applicable to the hump nose object. In addition, a prompt may be output that there is one or more contour points in each model for which the target tension value exceeds a threshold value, so that the user intuitively determines that the nasal prosthesis is not suitable for the augmentation rhinoplasty object.
Similarly, if the target tension value of each first model contour point is less than or equal to the first tension threshold and the target tension value of each second model contour point is less than or equal to the second tension threshold, the first model and the second model are indicated to be structurally complete, and therefore it can be determined that the nose prosthesis is suitable for the hump nose object. In addition, a prompt may be output that the tension condition of each model contour point does not exceed a threshold value, so that a user intuitively determines that the nasal prosthesis is suitable for the augmentation rhinoplasty object.
In one embodiment of the present application, after S340, further includes: and displaying the judging result of the applicability of the prosthesis on a nose augmentation effect image interface.
In one embodiment of the present application, after determining that the nasal prosthesis is suitable for the augmentation rhinoplasty object, further comprising:
and if deformation parameters generated by each model when the virtual model is placed are smaller than or equal to a preset deformation parameter threshold, outputting a prompt message that the nose prosthesis is a target nose prosthesis of the augmentation nose object.
It will be appreciated that the deformation parameters generated by each model may be preset by an administrator prior to the start of the augmentation rhinoplasty simulation procedure or determined by other reasonable means. If deformation parameters generated by each model when the virtual model is placed are smaller than or equal to a preset deformation parameter threshold, the nose augmentation simulation is not only not beyond the bearing extrusion force range of the nose tissues of the nose augmentation object, but also the deformation is within a preset range, namely the nose augmentation effect can reach the expected value, so that the nose prosthesis can be determined to be the target nose prosthesis of the nose augmentation object.
In the embodiment of the application, firstly, the tension of the nose skin of a nose augmentation subject, the tension of a nose prosthesis to be implanted into the nose of the nose augmentation subject, a nose body model and a nose skin model of the nose augmentation subject and a virtual model of the nose prosthesis are obtained; secondly, placing the virtual model between the nose body model and the nose skin model to obtain a nose augmentation effect image of the nose augmentation object; then, it is determined whether the nasal prosthesis is suitable for the augmentation-nasal subject based on the tension of the nasal skin, the tension of the nasal prosthesis, and the augmentation-nasal effect image. By the method, the device and the system, the applicability of each nasal prosthesis can be automatically judged, so that relevant personnel can be assisted in selecting the appropriate nasal prosthesis for the augmentation rhinoplasty object.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.
As shown in FIG. 3a, an embodiment of the present application provides an initial model state diagram for a nose body model.
It should be noted that, the tension value of each contour point in the nose body model of the augmentation rhinoplasty object is not changed in the augmentation rhinoplasty simulation process, that is, the nose body model is not deformed in the augmentation rhinoplasty simulation process.
As shown in fig. 3b, an embodiment of the present application provides an initial model state diagram of a virtual model of a nasal prosthesis placed over a nasal ontology model; wherein reference numeral 1 represents a nose ontology model and reference numeral 3 represents a virtual model of a nose prosthesis. In fig. 3b, it can be observed that there is a gap space between the virtual model of the nasal prosthesis and the nasal phantom, i.e. the virtual model of the nasal prosthesis is not attached to the nasal phantom.
As shown in fig. 3c, the embodiment of the present application provides an initial model state diagram that additionally shows a nose skin model on the basis of fig. 3 b; wherein reference numeral 1 represents a nose body model, reference numeral 2 represents a nose skin model, and reference numeral 3 represents a virtual model of a nose prosthesis.

In fig. 3d, it can be observed that the gap space between the nose body model and the nose skin model is reduced, which indicates that the nose skin model is deformed, and the virtual model of the nose prosthesis is pressed and gradually attached to the nose body model and the nose skin model.
As shown in fig. 3e, an embodiment of the present application provides another model state diagram after placement of a virtual model of a nasal prosthesis on a nasal ontology model; wherein reference numeral 1 represents a nose ontology model and reference numeral 3 represents a virtual model of a nose prosthesis.
