Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a portable facial trauma fracture reduction navigator. Background Art

[0002] Due to the special anatomical structure and location, the treatment of maxillofacial fractures is often restricted by the fracture site, blood vessels, nerves and adjacent organs. Therefore, the fracture incision is often required to be concealed and avoid important nerves, blood vessels and organs, making it impossible to complete the reduction of fractures in many parts (such as zygomatic bone and zygomatic arch fractures, nasal bone fractures, orbital bone fractures, etc.) under direct vision conditions, and closed reduction operations are required. In addition, with the development of digital surgery, computer-assisted navigation surgery is becoming more and more common. It can guide the closed reduction of maxillofacial fractures under the condition of "real-time visualization" on the computer screen and effectively conduct intraoperative evaluation.

[0003] After searching, a maxillofacial fracture reducer suitable for computer-assisted navigation surgery was disclosed with the publication number CN205514867U, which overcomes the problems of non-standardized instruments, complicated and cumbersome equipment of surgical instruments in computer navigation systems, and mismatch between instruments and tripods in the prior art. The technical solution of the utility model includes a reduction rod, a tripod, and a connecting rod between the two. The reduction rod is composed of three parts in sequence: a working end, a handheld end, and an identification end. The tripod includes positioning rod one, positioning rod two, and positioning rod three, and the ends of the three positioning rods are all threaded;

[0004] During facial surgery on fractures, it is often necessary to use a navigation device with an optical tracking system to navigate and repair the robotic arm. However, the existing navigation devices with optical tracking systems are relatively large in size due to the need to be equipped with structures such as a display, and are mostly used in indoor operating rooms. When facial trauma or facial fractures need to be repaired outdoors or in the wild, the device is inconvenient to carry due to its appearance, making it impossible to move the device to the outdoors or in the wild for use. In addition, during the movement of the navigation device, accidental collisions may affect the structure of the navigation device and cause damage to the navigation device. Summary of the invention

The user rotates the transmission rod, and the transmission rod drives the two meshing gears to rotate through the transmission gear, and the meshing gear drives the rotating shaft to rotate, so that the mounting frame rotates, so that the displays on both sides of the lifting seat are unfolded, which is convenient for the unfolding and use of the displays, and the displays are retracted and folded, so that the displays can be protected when the navigation box body is moved and carried. By folding the whole device, it is convenient for the user to carry it, and it is convenient for the user to drive the whole device for mobile turnover use, which is conducive to first aid for patients outdoors or in the wild, and expands the use environment.

[0018] 2. The portable facial trauma fracture reduction navigator, the user rotates the rotating rod, the rotating rod drives the two changing rods to rotate through the bevel gear and the changing gear, the changing rod drives two of the first adjusting screws to rotate through the bevel gear and the changing gear, the rotating two first adjusting screws drive the other two first adjusting screws to rotate through the transmission sprocket and the transmission chain, so that the four first adjusting screws can rotate synchronously, the lifting plate moves upward along the first adjusting screws under the action of the threaded hole, the lifting seat moves out of the navigation box body, and the lifting seat is convenient for use, the user rotates the rotating head, the rotating head drives one of the second adjusting screws to rotate through the bevel gear and the changing gear, the two second adjusting screws rotate synchronously through the transmission sprocket and the transmission chain, the lifting seat can adjust the height of the lifting seat under the action of the thread, so as to facilitate the adjustment of the height of the lifting seat, and the height of the display and the optical tracking head can be adjusted.

[0019] 3. For the portable facial trauma fracture reduction navigator, the user pulls the card rod, which drives the movable block to move, compresses the compression spring, and drives the card plate to move. The card plate can drive the card block to move, so that the card block rotates from the inside of the card hole, and the rotating head can rotate inside the rotating groove, so that the position of the assembly frame can be adjusted.
