Description

Technical Field

[0001] This utility model relates to the field of spinal orthopedics, specifically to an automatically adaptable orthopedic device. Background Technology

[0002] Scoliosis orthotics are designed to correct spinal deformities in three-dimensional space using multiple sets of "three-point forces" based on each patient's body deformity. However, in the production of modern spinal orthotics, the design of the orthotine model is not easily quantifiable. First, a physician takes X-rays and performs a 3D scan. Then, a drafting engineer imports the scanned files into drafting software, adjusts the digital model in the 3D modeling software based on experience and the X-ray images, and finally exports the drawn orthotine file for printing. Therefore, the manufacturing of orthotics faces the following problems: 1. The orthotic fitting process relies too heavily on the personal experience of technicians. During the customization process, doctors or technicians need to consider the patient's body shape and X-ray images to manually determine the direction and intensity of the corrective force. This lacks precise and quantitative data support, and the fitting effect varies from person to person, making it highly subjective. 2. In existing devices, the application, detection, and data recording of corrective pressure are often completed by multiple devices. Patients need to frequently change positions or connect devices. The separation of pressure regulation and detection makes the process cumbersome and inefficient, and also increases the error and difficulty of operation. 3. Although some pneumatic orthotics or adjustable braces integrate airbag structures, they usually cannot achieve individual pressurization and pressure recording of multiple airbag areas, making it difficult to meet the multi-area correction needs of complex spinal deformities and lacking the ability to independently control and monitor multiple points. 4. Most testing devices currently on the market cannot be directly integrated with 3D modeling or finite element analysis processes, resulting in a lack of linkage between subsequent design and biomechanical models. This makes it impossible to use the test data in the integrated design process, leading to long customization cycles and delayed feedback.

[0003] Based on this, the present invention designs an automatically adaptable orthopedic device to solve the above problems. Utility Model Content

[0006] Furthermore, the testing instrument is also equipped with an emergency stop button that is electrically connected to the main control unit.

[0007] Furthermore, the airbag assembly consists of 46 independently controlled airbag units.

[0013] Compared with the prior art, the advantages of this utility model are: 1. Integrated operation process. In traditional testing processes, pressurization, testing, and data recording are typically performed on multiple devices, requiring manual coordination. This invention, however, achieves integrated operation, automatically coordinating the work of multiple functional modules, significantly improving testing efficiency and consistency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] In some embodiments, please refer to the accompanying drawings.

A curved model matching and conforming to most human backs is generated in advance using a structured light scanner. Then, various sizes of the main body 21 of the brace are formed by CNC or 3D printing technology. At the same time, the inner side of the main body 21 of the brace has reserved airbag mounting slots for installing airbag components 22.

[0020] In this embodiment, the airbag assembly 22 consists of 46 independently controlled airbag units, each of which can be appropriately deformed and is made of flexible TPU. The airbag units are distributed based on the three-point mechanical principle of spinal correction: "main force point + reaction force point + control point," and the corrective effect is generated through the interaction of the three forces. Each airbag is equipped with an independent number to support subsequent pressure adjustment and data acquisition.

[0021] In this embodiment, the fixing component 23 adopts a structure of straps and rivets to facilitate the patient to quickly put on the brace body 21.

[0022] In some embodiments, please refer to the accompanying drawings.
