Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a multifunctional tibial plateau collapse fracture reduction push rod. Background Art

[0002] Tibial plateau fractures, as a common type of fracture, account for approximately 2% to 3% of all fractures in the body. Among them, lateral plateau fractures account for 55% to 70%. Clinically, the Schatzker classification is widely used to classify tibial plateau fractures. Among them, type II and type III fractures correspond to lateral plateau splitting compression fractures and lateral central compression fractures, respectively. For both types of fractures, the core steps of surgical treatment involve the prying reduction and bone grafting of the articular surface.

[0003] The surgical steps usually include: first, open a window on the cortical bone (or directly through the split of the fracture), and then use a thin metal rod to lift the collapsed joint surface. With the help of X-ray fluoroscopy, the doctor can accurately judge the reduction of the joint surface. Next, remove the metal rod and implant bone tissue under the joint surface to provide support. Finally, fix the fracture site with a steel plate and screws to ensure its stability and healing.

[0004] However, in the existing surgical process, removing the metal rod supporting the joint surface before performing bone grafting may cause a series of problems. First, the already reduced joint surface may be displaced due to this step. Second, the position of the bone graft is difficult to control accurately. If it is implanted too deep, it may over-lift the joint surface; conversely, if the implant position is insufficient, it may not effectively support the joint surface, thus affecting the surgical effect.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a multifunctional tibial plateau collapse fracture reduction rod. Utility Model Content

[0023] According to the above scheme, in this embodiment, when in use, the doctor can operate the push rod 2 through the handle 1, and use the spur portion 21 and the spike portion 31 to reset the collapsed tibial plateau. The micro camera 22 can take real-time pictures of the reset of the joint surface and transmit the image to the display screen 23 for the doctor's reference.
