[0033] Please refer to Figure 1 The present application provides a kind of face plastic evaluation equipment in the embodiments of the present application, comprising:

[0034] Head fixing assembly, for fixing the head of patient;

[0035] 3D scanner 200, for obtaining the overall facial surface point cloud data of patient;

[0036] Scanning probe 300, for obtaining the data information of the local target skin surface and subsurface three-dimensional structure of patient;

[0037] Puller 400, for determining the maximum degree of pull that patient can withstand, cooperates with 3D scanner and scanning probe, realizes the measurement of skin extension surface area.

[0038] The intelligent control assembly 600 is electrically connected with the 3D scanner 200, the scanning probe 300 and the puller 400 respectively.

[0039] The 3D scanner 200 transmits the measured data to the intelligent control assembly 600 after the patient's head is fixed by the head fixing assembly, and the intelligent control assembly 600 analyzes the data to generate an original 3D model of the patient's face. On the basis of doctor-patient communication, the data measured by the scanning probe 300 and the puller 400 are combined, and the intelligent control assembly 600 analyzes the data to generate a target 3D model and a surgical plan.

[0040] It should be noted that the 3D scanner 200 can be mobile, and point cloud data is used to establish a digital facial 3D model to determine the area of the facial plastic surgery and evaluate the facial beauty, and measure the size of some key parts. The scanning probe 300 can be a mobile OCT scanning probe 300, which is a non-destructive testing method that can accurately quantify the parameters of the three-dimensional structure of the skin, and realize non-immersed, non-contact and non-destructive testing of the skin. The scanning probe 300 can quantify the skin roughness and evaluate the skin extensibility. It can also be used to obtain three-dimensional optical attenuation coefficient information and blood perfusion information of the skin in the facial acne, burn and other scar areas, and evaluate the degree of scar and internal vascular network. The puller 400 obtains the maximum degree of skin stretching that the patient can withstand, and cooperates with the 3D scanner 200 and the scanning probe 300 to realize the measurement of the skin extension surface area.

[0041] It can be understood that the patient's head is fixed by the head fixing assembly, and the point cloud data of the patient's facial surface is obtained by the 3D scanner 200, which can generate an original 3D model of the patient, realize the measurement and analysis of various parameters of the patient's face, and also obtain the data information of the three-dimensional structure of the patient's facial skin surface and subsurface by the scanning probe 300, which can realize the evaluation of the skin extensibility. In addition, the maximum degree of skin stretching that the patient can withstand is obtained by the puller 400, which cooperates with the 3D scanner 200 and the scanning probe 300 to realize the measurement of the skin extension surface area. Therefore, the facial plastic evaluation device can not only measure and analyze various parameters of the face, but also quantitatively evaluate the skin characteristics.

[0042] In one embodiment, the puller 400 includes a pulling rod 401 for pulling the patient's face, a control member 402 fixed to the pulling rod 401, a height adjusting member 403 and a force adjusting member 404, and the height adjusting member 403 and the force adjusting member 404 are electrically connected with the control member 402.

[0043] It should be noted that the puller 400 is used to determine the maximum degree of pull that the patient can bear, to assist in the measurement of the skin surface area in the nasal plastic surgery and skin plastic surgery. Specifically, the puller 400 can be used for effective exercise of pre-plastic nasal pulling, to assist in gradually increasing the pulling degree and ensuring effective pulling; under the condition of fixed pulling degree, 3D scanning imaging is carried out to obtain the maximum extension degree of the nasal skin, and whether the nasal pulling effect meets the requirements of the prosthesis implantation is evaluated by the doctor; 3D scanning imaging is assisted to avoid imaging obstruction caused by traditional hand pulling and difficult to compare before and after, to provide quantitative analysis of nasal extension and comparison of the effects before and after pulling exercise. In addition, the puller 400 can be used for skin surface area calculation in skin wrinkle removal surgery, to assist the doctor in formulating wrinkle removal plastic surgery plan.

[0044] The puller 400 is used in combination with the scanning probe 300, since the scanning probe 300 is used to obtain the skin parameters of the patient, to measure the skin roughness of the patient, to evaluate the skin extensibility, and to calculate the area of the skin required for implantable plastic surgery, to guide the patient to use the puller 400 for pulling operation with basis, to avoid the patient from being damaged by the puller.

[0045] It can be understood that the pull rod 401 is provided with a fixing clamp, which clamps the part to be pulled or the specific part of the face to be pulled. Since the control member 402 is fixed with the pull rod 401, the control member 402 provides the pulled part of the face with the pulling force suitable for the pulled part of the face through the pull rod 401. The height adjusting member 403 can be a height adjusting knob, which is used to adjust the height during pulling. The force adjusting member 404 can be a force adjusting knob, which is used to adjust the force during pulling. The data during pulling is transmitted to the intelligent control assembly 600, and the intelligent control assembly 600 displays the related pulling parameters on the display 700, such as pulling angle, pulling height, pulling force, etc.

[0046] Specifically, the intelligent control assembly 600 includes a control module, a case database and a surgical plan generation module. The control module is electrically connected with the scanning probe 300, the 3D scanner 200 and the puller 400 respectively. The surgical plan generation module is electrically connected with the control module and the case database respectively.

[0047] It should be noted that the control module is used to establish a 3D model of the patient's face, measure the size of some key parts, quantify skin roughness, evaluate skin extensibility and obtain patient skin stretching parameters; the case database is used to store data of aesthetic standards of plastic projects or data of successful plastic cases, such as the information contained in the facial aesthetic database, including facial index, Ricketts cosmetic line, "three courts and five eyes" and "four highs and three lows" of facial contour or other facial organ aesthetic evaluation standards, which are used to guide the plastic surgery of the patient; the surgical plan generation module is used to generate a surgical plan. When the control module, the case database and the surgical plan generation module perform software data operation, existing software such as Windows system, MacOS system, Linux system, iOS system, Android system, etc. is adopted.

[0048] It can be understood that the intelligent control component 600 can be used to control the 3D scanner 200, the scanning probe 300 and the stretcher 400, the 3D scanner 200, the scanning probe 300 and the stretcher 400 transmit the measured data to the control module, the control module parameterizes the obtained data, establishes a 3D model of the patient's face, measures and compares the obtained parameters, the control module transmits the processed data to the surgical plan generation module, the surgical plan generation module compares the data processed by the control module with the data in the case database, generates a preliminary surgical plan, and adjusts the original 3D model data of the patient in combination with the results of communication between the doctor and the patient (such as skin texture, skin extensibility, facial appearance, plastic satisfaction, etc.), and generates a final surgical plan after operation.

[0049] In order to fix the patient's head, the head fixing component includes a support 103, a first fixing member 101 and a second fixing member 102, the first fixing member 101 and the second fixing member 102 are installed on the support 103 in a spaced manner, the first fixing member 101 is arranged above the second fixing member 102, the first fixing member 101 surrounds and fixes the forehead of the patient, and the second fixing member 102 surrounds and fixes the chin of the patient, so that the forehead and the chin of the patient are fixed, and the accuracy of the data obtained after scanning by the 3D scanner 200 and the scanning probe 300 is effectively ensured.

[0050] In a preferred embodiment, the facial plastic evaluation device further comprises a 3D printer, and the 3D printer is electrically connected with the intelligent control component 600. The intelligent control component 600 transmits the generated original 3D model data of the patient's face and the adjusted target 3D model data to the 3D printer, and the 3D printer prints the original 3D model of the patient and the adjusted target 3D model to form a solid object, which facilitates the communication of the surgical plan between the doctor and the patient.

[0051] In addition, the face plastic evaluation device further comprises a display 700 electrically connected with the intelligent control assembly 600, which is used to display the 3D model of the patient's face and the surgical plan generated by the intelligent control assembly 600, and can also display various parameters in the evaluation process, such as the pulling parameter, etc., which is beneficial for the doctor and the patient to view.

[0052] In order to be installed and mounted, the face plastic evaluation device further comprises a mounting seat 500, which is used to install the 3D scanner 200, the scanning probe 300 and the display 700.

[0053] The embodiment of the present application also provides a method for the face plastic evaluation device, which comprises the following steps:

[0054] Fixing the head of the patient to the head fixing assembly;

[0055] Turning on the 3D scanner 200 to obtain the overall facial surface point cloud data of the patient and measure the key size value;

[0056] Turning on the scanning probe 300 to obtain the local target skin surface and the three-dimensional structure data under the surface of the patient's face, and evaluate the skin roughness and the skin extensibility;

[0057] Starting the puller 400 to determine the maximum pulling degree that the patient can bear, cooperating with the 3D scanner and the scanning probe to realize the measurement of the skin extension surface area.

[0058] Transmitting the data obtained by the 3D scanner 200 to the intelligent control assembly 600, and generating the original 3D model of the patient's face by the intelligent control assembly 600 through data analysis; on the basis of the doctor-patient communication, combining the data measured by the scanning probe 300 and the puller 400, and the data analysis of the intelligent control assembly 600, generating the target 3D model and the surgical plan.

[0059] It can be understood that the 3D scanner 200, the scanning probe 300 and the puller 400 transmit the measured data to the control module, the control module parameterizes the obtained data, establishes a 3D model of the patient's face, measures and compares the obtained parameters, the control module transmits the processed data to the surgical plan generation module, the surgical plan generation module compares the data processed by the control module with the data in the case database, generates a preliminary surgical plan, and adjusts the original 3D model data of the patient in combination with the results of the communication between the doctor and the patient (such as skin texture, skin extensibility, facial shape, and satisfaction with plastic surgery), and finally generates the final surgical plan through operation. The method not only can measure and analyze various parameters of the face, but also can quantitatively evaluate the skin characteristics, and finally generate a preliminary surgical plan through the intelligent control component 600 by comparing and analyzing the scanned data, which has good applicability.

[0060] Specifically, if the nose needs to be reshaped, the patient fixes the head on the head fixing component, places the chin at the second fixing piece 102, and fixes the forehead by the first fixing piece 101. Start the 3D scanner 200 to scan the patient's face, obtain the point cloud data of the patient's face, establish a 3D model, and measure various parameters of the patient's nose, such as the length, width, protrusion of the nose tip, nasolabial angle, nasal facial angle, and precise data of the aesthetic subunit of the nose.

[0061] The patient's nose can be pulled using the control piece 402. During the pulling process, the patient adjusts in real time through the height adjusting piece 403 and the force adjusting piece 404 of the puller 400. The patient can select different pull rods 401 when pulling the nose. The fixing clamp at the head of the pull rod 401 can be a disposable nose cover, a nose tip clamp, a columella nasi clamp, or a ala nasi clamp. The disposable nose cover can be inserted into the nostril to test the pulling effect. The nose tip clamp can pull the nose back and the nose tip in the forward and downward directions. The columella nasi clamp can clamp the columella nasi to pull it downward and forward. The ala nasi clamp can clamp the ala nasi to pull it downward. The pulling force needs to reach the maximum bearing capacity of the patient, and the pulling force at this time is recorded. At the same time, start the 3D scanner 200 to scan the patient's nose and obtain the surface area extension value of the nose. Start the scanning probe 300 to obtain the skin roughness, skin extensibility and other parameters of the patient's nose, as well as the three-dimensional optical attenuation coefficient information and blood perfusion information of the skin in the scar area such as facial acne and burn, and evaluate the scar degree and internal blood vessel network.

[0062] According to the obtained parameters of the patient's face and nose, comparison is made with the aesthetic standard, such as the ideal nose length, i.e. the distance from the rhinion to the tip of the nose, should be equal to the distance from the stomion to the submental point, and the tip protrusion is equal to the ideal nose length x 0.67; the nasofrontal angle, the ideal value is about 25-30°, for Asians, the forehead is relatively low, and the nasofrontal angle is slightly larger than the standard; the nasolabial angle, the ideal angle, female is 95-100°, male is slightly smaller than female, 90-95°; the nasofacial angle, the ideal value is about 120-125°, based on the comparison result, the nose 3D model is adjusted, not only to make the appearance of the nose meet the aesthetic standard, but also to make the proportion of the nose and the face more balanced. Although all angles are fixed, each face is unique, and the proportion of the nose and the face is more balanced during the nose comprehensive plastic surgery.

[0063] The intelligent control component 600 can automatically generate a nose plastic surgery scheme according to the comparison data, and the doctor can use the automatically generated scheme to communicate with the patient, and then adjust the scheme; or the doctor can manually design a surgery scheme according to the face plastic surgery evaluation data.

[0064] If it is necessary to perform face wrinkle removal, the patient's head is fixed on the head fixing component, the chin is placed at the second fixing piece 102, and the forehead is fixed by the first fixing piece 101. The 3D scanner 200 is started to scan the patient's face to obtain point cloud data of the patient's face and establish a face 3D model. The scanning probe 300 is started to measure the roughness and skin extensibility of the face skin. The puller 400 is clamped and fixed on the skin where wrinkle removal is needed. During the pulling process, the patient adjusts in real time through the height adjusting piece 403 and the force adjusting piece 404 of the puller 400. The pulling direction can be forward pulling, downward pulling and lateral pulling, and the pulling force needs to reach the maximum bearing degree of the patient. Then the pulling angle, pulling height and pulling force at this time are recorded, and the 3D scanner 200 is started to scan the patient's face to obtain the surface area extension value of the face skin, and the scanning probe 300 is started to obtain the skin roughness and skin extensibility of the patient.

[0065] According to the obtained parameters of the patient's face, comparison is made with the aesthetic standard, and the intelligent control component 600 generates a preliminary face wrinkle removal surgery scheme. The doctor can use the generated scheme to communicate with the patient, and then adjust the scheme; or the doctor can manually design a surgery scheme according to the face plastic surgery evaluation data.

[0066] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection claimed by the present application.
