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

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the invention clearer, the invention will be further elaborated below in conjunction with the accompanying drawings.

[0032] In this example, see figure 1 As shown, a three-dimensional closed reduction device for femoral shaft fractures includes a distal assembly, a proximal assembly and an adjustable connection assembly, and the distal assembly and the proximal fixation assembly are connected to each other through an adjustable connection assembly;

[0033] The adjustable connection assembly includes a long screw 11;

[0034] The distal assembly includes a sleeve fixing clip 21, a sleeve screw I22, a sleeve screw II23 and a screw 24; the sleeve of the sleeve screw I22 is sleeved on the rod body of the sleeve screw II23, The sleeved screw I22 and the sleeved screw II23 are vertically connected to each other, the sleeve of the sleeved screw II23 is placed on the distal end of the long screw 11, and the ...

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...
