Technical Field
The invention relates to the field of medical instruments, in particular to a tibia platform positioner set.
Background
The tibia platform is arranged in the knee joint, namely the contact surface of the tibia and the lower end of the femur, and the periphery of the tibia platform is wrapped by articular cartilage. The tibial plateau is an important bony structure that constitutes the knee joint and is capable of supporting weight loads above the knee joint. However, tibial plateau is prone to collapse fractures in trauma. And when the tibia plateau is fractured, the structures such as the internal collateral ligament, the external collateral ligament, the anterior cruciate ligament and the posterior cruciate ligament of the knee joint can be correspondingly damaged. After fracture of the tibial plateau occurs, surgical treatment should be timely adopted to achieve the purpose of reduction. If not treated in time, serious sequelae may be left, which affects the quality of life of the patient.
The existing tibia platform positioner has poor adaptability due to small adjusting range, and meanwhile, the positioner on the market is integrated, the application range is small, the use is inconvenient due to the blocking of the lower leg, the operation difficulty is increased, and the operation progress is delayed. At present, this situation is not solved at all, and therefore measures are necessary to solve the situation.
