Abstract

The invention discloses an automatic traction device for a tibia fracture setting operation. A supporting frame has a triangular structure and is used for supporting the lower limbs of a patient to form and keep a leg bending state. The supporting frame comprises a supporting bottom face arranged horizontally, a thigh bearing face and a shank bearing face, wherein the thigh bearing face and the shank bearing face are arranged at the two ends of the supporting bottom face oppositely; the ends of every two adjacent faces are hinged; and the lengths of all the faces can be adjusted and locked through an edge adjusting mechanism. The tibia kirschner wire installation position is provided with two tibia kirschner wire installation structures arranged on the two sides of the shank bearing face respectively. The automatic traction device is stable in operation, the operation difficulty can be lowered, and the broken bone traction reduction quality is improved.

Description

technical field

[0001] The invention relates to the technical field of orthopedic medical devices, in particular to an automatic traction device for tibial fracture osteosynthesis, which is suitable for tibial intramedullary nail implantation and percutaneous bone plate implantation osteosynthesis. Background technique

[0002] Tibial fractures are common clinical fractures. Due to the strong muscle strength of the legs, patients with tibial fractures often experience shortening deformities under the pull of the muscles. It is difficult to reset, restore its length and maintain it effectively during the operation. If the anatomical reduction cannot be performed during the operation, complications such as malunion and poor alignment of the lower limbs may occur after the operation, which may lead to traumatic arthritis or osteoarthritis, seriously affecting the limb function and quality of life of the patient.
