[0034] a photographic device for capturing a facial image; and

[0035] a processor connected to the server and the photographic device, receiving the facial image and obtaining at least one lifting parameter;

[0036] Among them, the at least one lifting parameter includes at least one preoperative characteristic distance, at least one postoperative characteristic distance corresponding to the at least one preoperative characteristic distance, and a maximum lifting distance. The processor uses the at least one lifting force calculation formula to calculate the at least one lifting parameter according to the maximum lifting distance, obtains at least one lifting force value corresponding to the at least one lifting force calculation formula, and generates an evaluation table, in which the at least one lifting force value and the at least one lifting distance corresponding to the at least one lifting force value are listed, and the sorting number of the at least one lifting distance is listed individually according to the order of the value size.

[0037] Each of the above devices may independently include a storage device, a processor and / or a communication chip. Examples of storage devices include hard disks, flash drives, memory, memory cards, etc. Examples of processors include integrated circuits such as microcontroller units, microprocessors, digital signal processors, application-specific integrated circuits (ASICs), logic circuits, or other similar components or combinations of the above components.

[0038] In order to solve the problems in the background technology, the present invention proposes a lifting surgery analysis system capable of providing a surgical evaluation. Figure 1 As shown, the lift surgery analysis system 100 of the present invention includes a server 110 , a photographing device 120 and a processor 130 .

[0039] The server 110 provides at least one lifting force calculation formula, and the at least one lifting force calculation formula corresponds to at least one lifting wire placement method. In this embodiment, the server 110 provides five lifting force calculation formulas, corresponding to Figure 2A The double line in and out of the single hole shown, Figure 2B The parallel double lines shown, Figure 2C The V-shaped line shown, Figure 2D The U-shaped line shown and Figure 2E The single line shown is shown in Table 1. In each formula, x represents the pulling distance (unit: mm) and y represents the pulling force value (unit: kgf).

[0040] Table 1 Wire lifting formulas for different wire placement methods

[0041] Line placement Thread lift formula (1) Single hole for double lines y=0.1x+0.01 (2) Flat double line y=0.17x-0.02 (3) V-type y=0.15x-0.02 (4)U shape y=0.15x-0.01 (5) Single line y=0.12x-0.01

[0042] Please refer to Figure 3 , Figure 3 It is a curve diagram of the lifting force calculation formula in Table 1. The line placement methods corresponding to curves A, B, C, D, and S are single-hole in-and-out double lines, parallel double lines, V-shaped lines, U-shaped lines, and single lines, respectively.

[0043] The processor 130 is connected to the server 110 and the photographic device 120, receives the facial image captured by the photographic device 120 and obtains at least one lifting parameter. In order to understand the ideal appearance required by the customer, the lifting surgery analysis system 100 captures the facial image of the customer through the photographic device 120, and the processor 130 uses a photo editing program to retouch the facial image to obtain the at least one lifting parameter. For example, the processor 130 uses a popular AI photo editing software to obtain the desired plastic surgery appearance to present the image distance before and after the surgery. Therefore, the at least one lifting parameter includes at least one preoperative characteristic distance, at least one postoperative characteristic distance corresponding to the at least one preoperative characteristic distance, and a maximum lifting distance. The processor 130 calculates at least one distance difference between the at least one preoperative characteristic distance and the corresponding at least one postoperative characteristic distance. If one of the at least one distance difference is less than the maximum lifting distance, the processor 130 brings the distance difference into the above-mentioned lifting force calculation formula for calculation to obtain at least one lifting force value corresponding to the distance difference.

[0044] like Figure 4 As shown, X is the preoperative characteristic distance between the coccyx of the two eyes, a is the preoperative characteristic distance between the upper lip bead and the profile, X' is the postoperative characteristic distance between the coccyx of the two eyes, a' is the postoperative characteristic distance between the upper lip bead and the profile, the difference between X and X' is the lifting distance between the coccyx of the two eyes, and the difference between a and a' is the lifting distance between the upper lip bead and the profile.

[0045] Please refer to Figure 5 , Figure 5 It is a schematic diagram of the lifting distance and lifting angle in the present invention. The value of θ is the direction of the lifting line and the lifting angle of the self-set facial baseline. The value of r is the actual lifting distance. The displacement distance can be calculated by subtracting the length of a' from the length of a, that is, (a'-a) = r*Cosθ. The value of c is the distance between the final exit point of the lifting line and the point a' as the rising distance, that is, r*Sinθ. R is the maximum lifting distance. The value exceeding R will cause risks such as wire loosening and tissue tearing. The lifting force corresponding to the lifting distance r is f, which can be calculated by the formula in Table 1 above (substitute r into x and f into y), as shown in Table 2 below. If the distance difference is less than the maximum lifting distance, the processor 130 will bring the distance difference into the above-mentioned lifting force calculation formula for calculation to obtain the lifting force value corresponding to the distance difference.

[0046] Table 2 Parameters of the wire lifting formula for different wire placement methods

[0047]

[0048]

[0049] The maximum pulling force corresponding to the maximum pulling distance R is F, which can be calculated by the formula in Table 1 above (substituting R into x and F into y), and an evaluation table Table 3 is generated accordingly.

[0050] Table 3 Evaluation table corresponding to different line placement methods

[0051]

[0052] As shown in Table 3, the evaluation table provides the wire pulling force limit data for reference in the operation of the corresponding embodiment. If the pulling line exceeds the limit data, it will cause tissue tearing, internal inflammation and swelling. The single-hole entry and exit double-line operation will cover the muscle tissue, and the surgical wound is only at the penetration hole. When the muscle tissue is pulled, it will present a cone shape. At this time, if the pulling force exceeds 0.38kgf, or the pulling distance exceeds 5mm, it will cause the wire to loosen, tissue tearing, and internal inflammation and swelling of the muscle tissue. The parallel double-line operation will not cover the muscle tissue. The surgical wound is only at the penetration hole. When the muscle tissue is pulled, it will present a middle depression. At this time, if the pulling force exceeds 0.55kgf, or the pulling distance exceeds 4mm, it will cause the wire to loosen. The V-shaped and U-shaped line operation will cover the muscle tissue. The surgical wound is located at the penetration hole and the bottom of the V and U. When the muscle tissue is pulled, it will present a middle depression. At this time, if the pulling force exceeds 0.55kgf, or the pulling distance exceeds 5mm, it will cause muscle tissue tearing. Single-thread surgery does not cover muscle tissue, and the surgical wound is only at the penetration hole. When the muscle tissue is pulled up, it presents a cone shape. At this time, if the pulling force exceeds 0.34kgf, or the pulling distance exceeds 2.7mm, the thread will become loose. The greater the maximum pulling force, the better the maintenance. Exceeding the maximum pulling force or the maximum pulling distance will cause the thread to be unhooked or the tissue to be torn, which can be compensated by adding a pull line.

[0053] In addition, in addition to listing the at least one pulling force value and the at least one pulling distance corresponding to the at least one pulling force value in the evaluation table, the at least one pulling distance is also listed in order of numerical value, and an evaluation table 4 is generated accordingly.

[0054] Table 4 Evaluation table

[0055]

[0056]

[0057]

[0058] As shown in Table 4, the evaluation table provides the wire pulling force limit data in the operation corresponding to an embodiment for reference, and also provides the number of needle insertion wounds, the difficulty of surgical skills, the affected tissue area, the number of wires used in the same area, and the severity of the wound corresponding to different wire placement methods. The affected tissue area, the number of wires used in the same area, and the severity of the wound can be simulated by observing the changes in the silicone after the pulling test.

[0059] The order of the need for knotting in the line placement method from low to high is single hole in and out double line, parallel double line, V and U-shaped line, single line. Since the single line has no support and is easy to sag, it is more necessary to tie a knot. The double line can maintain a certain degree of support in both the upper and lower directions without tying knots, so it is less necessary.

[0060] Single-hole in and out double-line surgery will cover muscle tissue, the surgical wound is only at the entry hole, and the number of needle wounds is 2. Parallel double-line surgery will not cover muscle tissue, the surgical wound is located only at the entry hole, and the number of needle wounds is 2. V-shaped and U-shaped line surgery will cover muscle tissue, the surgical wound is located at the entry hole and the bottom of the V and U, and the number of needle wounds is 3. Single-line surgery will not cover muscle tissue, the surgical wound is only at the entry hole, and the number of needle wounds is 1.

[0061] The difficulty of the surgical techniques for suture placement is ranked from difficult to easy as U-shaped suture, V-shaped suture, single-hole entry and exit double suture, parallel double suture, and single suture.

[0062] The order of the wire placement methods that can affect the tissue area from most to least is U-shaped wire, V-shaped wire, single hole in and out double wire, parallel double wire, single wire. The area is related to whether the muscle tissue is covered, which will also determine the number of wires used.

[0063] The number of wires used in the same area of ​​the suture placement method is from most to least, in order of single wire, single hole in and out double wire, parallel double wire, U-shaped and V-shaped wire. The number of wires used will affect the total number of wounds in the operation and the price of the operation.

[0064] The wound severity of the suture placement methods is ranked from high to low as U-shaped suture, V-shaped suture, single-hole in-and-out double suture, parallel double suture, and single suture. The wound severity is related to the affected area, maximum pulling force, and pulling distance.

[0065] The face lift analysis system provided by the present invention can capture the customer's facial image through video shooting, and calculate and analyze the lifting distance and lifting force corresponding to different face lift thread placement methods according to the customer's desired surgical effect and post-surgery image, providing doctors with a scientific basis before surgery as a reference for formulating face lift strategies and reducing surgical risks.

[0066] Although the present invention provides the above preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention may make modifications and alterations without departing from the spirit and scope of the present invention.
