Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to an auxiliary positioning instrument for a hollow fracture nail. Background Art
[0002] When a fracture occurs and there is significant dislocation, surgical intervention is indeed necessary. Depending on the location and situation of the fracture, the doctor may choose different surgical fixation methods. For simpler fractures, especially long bone fractures, cannulated nail fixation is a common choice. By passing the cannulated nail through the fracture ends, the fracture can be realigned and stable support can be provided to promote healing. For more complex fractures or those that require stronger support, such as pelvic or spinal fractures, plate fixation is usually chosen. This method uses metal instruments to fix the plate to the fracture, providing stronger support and fixation, ensuring that the fracture ends remain in the correct position during the healing process. At present, most doctors use cannulated nails for fixation through manual positioning. The lack of auxiliary positioning instruments will increase the risk of dislocation of the fracture ends. Accurate fracture reduction is very important for successful treatment and healing. Without auxiliary tools, doctors need to rely on experience and feeling to determine the position of the fracture ends, which may not be accurate enough.
