Three-dimensional closed repositor for femoral shaft fracture and usage method thereof

Abstract

The invention discloses a three-dimensional closed repositor for femoral shaft fracture and usage method thereof. The three-dimensional closed repositor for femoral shaft fracture comprises a far-endassembly, a near-end assembly, and an adjustable connecting assembly, and the far-end assembly and the near-end fixing assembly are connected to each other through the adjustable connecting assembly.The three-dimensional closed repositor for femoral shaft fracture can carry out three-dimensional reset on fracture, and can reduce fracture overlapping and the displacement of a coronal plane and a sagittal plane; and when in use, the three-dimensional closed repositor for femoral shaft fracture can accurately carry out reduction and save manpower and time, structure and operation are simple, andthe cost is low.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a three-dimensional closed reducer for femoral shaft fractures. Background technique [0002] Fractures of the femoral shaft account for about 6% of all fractures in the whole body. Selecting the appropriate treatment method in fracture treatment can protect the periosteum and soft tissue blood supply around the fracture to the maximum extent. Minimally invasive implantation of internal fixation can promote fracture healing; [0003] At present, the preferred method for the treatment of femoral shaft fractures is closed reduction and internal fixation with interlocking nails. However, the thigh muscles are well developed, and shortening, angulation, and lateral displacement deformities often occur. Close reduction is required to keep the fracture end in a stable state. Very difficult; at present, manual reduction, traction table or femoral spreader are often used for re...

Problems solved by technology

[0003] At present, the preferred method for the treatment of femoral shaft fractures is closed reduction and interlocking nail fixation. However, the thighs are well-developed muscles, which often cause shortening, angulation, and lateral displacement deformities. Close reduction is required to keep the fracture end in a stable state. Very difficult; at present, manual reduction, traction table or femoral spreader are often used for reduction; these three methods can only be used for fracture traction to solve the shortening deformity of the fracture, but cannot reduce the displacement of the coronal and sagittal planes of the fracture
