Definitions

  • This invention is related to a tool to determine the exact location and amount of injection or removal for body modeling, and also is related to a tool to evaluate the compliance of the applicant’s body shape with the pre- determined result considering body form changes in standing, lying and other body postures.
  • Different methods are used to shape and beautify the body form. Some of these methods involve removing fat from specific parts of the body, which may be injected into other parts needing volume increase. In addition to fat injection, other fillers are used to shape the body, the composition of which is compatible with the body tissue.
  • Design software has been used to perform injection in different parts of the body, through which the result of body augmentation or reduction surgery can be simulated, and the injection points and the amount of injection in each point are also determined.
  • the injection points are then displayed to the operator in various ways during the surgery so that the operator can better understand the injection process.
  • the simulation of the result and the injection points are determined according to the body posture in the standing form, while during the injection process, the applicant is often lying down. Also, using the previous methods, it is not possible to evaluate the compliance of the surgery result with the simulated one.
  • Patent US20160242853 entitled SYSTEMS AND METHODS FOR WEARABLE INJECTION
  • GUIDES filed by Elwha LLC at the US Patent Office indicates a method to determine filler injection points or any other injectable substance on the face or body.
  • one or more images of the application guide model are designed in the software that can identify the injection points.
  • a wearable injection guide is made using a 3D printer. This guide is made of materials that needles can penetrate. Accordingly, after the applicant has worn the guide, the operator can inject the filler by specifying the injection points. This procedure does not simulate the surgical outcome, and the applicant has no idea about the outcome of the filler injection. Besides, the operator cannot ensure the symmetry of the face as well as the desired shape.
  • the mentioned method does not provide information about the body form differences in standing and lying postures.
  • patent WO2019178287 entitled AUGMENTED REALITY TOOLS AND SYSTEMS FOR INJECTION at the US Patent Office.
  • the applicant using photos, video, genetic examination, medical data such as MRI or CT scan, the applicant’s 3D model is developed, in which the anatomy and location of veins, bones, glands, etc. are identified.
  • the applicant can see the filler injection outcome.
  • the operator can see the injection site and subcutaneous structures using the virtual reality glasses by looking at the applicant.
  • the invention also includes a system showing whether the injection is performed in the right place and direction during the filler injection.
  • the problem with this method is that after filler injection, the operator cannot accurately evaluate the compliance of the applicant's face with the simulation.
  • Using virtual reality glasses can also be difficult for the operator and can make the eye tired.
  • the present invention is designed to solve the mentioned problems. It is possible to simulate three-dimensional results of body volume augmentation and reduction surgeries as well as determine injection points in standing, lying, and other body postures by using the guide system designed in this invention. Also, using this system, the points’ location and the injection amounts in each point can be determined, and the operator/doctor/surgeon can examine the compliance of the actual rhinoplasty result with the simulated result physically and digitally at any time and ensure the achievement of the predetermined result.

  • the present invention is a control and guidance system for body augmentation and reduction cosmetic surgeries.
  • this invention using the output information of 3D scanners, a 3D image of the applicant or the area in need of surgery in standing, lying, and other body postures are made in related software. Then, through the body change design software, it is possible to observe the effect of tissue removal or filler injection in different areas of the body in standing posture and decide on the areas that the removal or injection is performed. After confirming the design of the ideal form in the standing posture, it is possible to simulate the result in the posture that the surgery is performed. For this purpose, the differences of 3D models in different body postures are examined before applying the changes, and as a result, based on the design of the ideal form in the standing posture, the result of the cosmetic surgery in the lying posture or other postures is simulated through the software.
  • the guidance system in this invention comprises a series of surgical guides ( Figure 1) made by 3D printers based on the final design in lying or other postures.
  • These surgical guides allow the operator/doctor/surgeon to check the compliance of applicant’s body shape with the predetermined design in lying or any other postures during the removal or injection process; in body reduction surgery, it is possible to check the mentioned compliance by placing these surgical guides on the applicant’s body.
  • body augmentation surgery by placing these guides on the desired area, it can be understood how much filler should be injected to achieve the predetermined form based on the distance of the guide from the body area ( Figures 2 and 3).
  • the guidance system also includes a processor device that uses a 3D scanner or a combination of several 3D scanners simultaneously to scan the applicant at any time during the cosmetic procedure (Figure 4).
  • the processor also has an internal memory that contains 3D simulation information of the result in different body postures, removal or injection points, and surgical guides’ location information.
  • a focused light-generating tool such as a laser, it is possible to display the removal or injection points on the applicant's body during the surgery.
  • the processor device also includes a camera that displays the applicant’s real-time image or the relevant body area on the screen during the surgery.
  • this device shows different points in blue and similar points in green on the applicant's image on the screen using artificial intelligence.
  • blue points change to green gradually. If a part of the body is increased or reduced too much, the points in that area turn red ( Figure 5).
  • the operator/doctor/surgeon does not want to see the real-time image of the camera, the image can be hidden, and only the difference between real-time 3D model and the simulated 3D result can be seen ( Figure 6). Accordingly, the operator/doctor/surgeon can realize the amount of change required and check the compliance of the result with the simulated one digitally.
  • the processor also shows the location of the surgical guides on the applicant's real-time image on the screen by accessing information about the exact location of the surgical guides on the 3D model of different body postures and performing a real-time scan at any time. Thus, by looking at the monitor, the surgical guide location can be determined. If the surgical guide is placed on the wrong area, the processor system compares the guide location in the 3D real-time model and predetermined 3D model and detects the wrong positioning of the guide using the artificial intelligence and warns.
