technical field

The utility model relates to fracture traction equipment, in particular to a three-dimensional closed reduction device for tibia and fibula fractures.

Background technique

The existing intraoperative lower limb reducer mainly uses a traction bed. The disadvantage is that it can only perform axial linear traction reduction for fractures, and cannot perform closed three-dimensional reduction for complex fractures such as rotation/angled/comminuted fractures. In actual use, the patient's fracture situation is often not single. Correction by different equipment will easily lead to prolonged treatment time and increase patient pain. If simultaneous correction requires multiple equipment to cooperate with each other, but the different correction equipment in the existing equipment It is usually difficult to cooperate with each other, so it can only be operated by the treatment staff with manual instruments, which increases the difficulty of the operation and physical exertion, and relies more on the experience of the medical staff.
