Problems solved by technology
[0003]Aiming at the problem that current fracture positioning and fixation devices have poor flexibility in multi-angle adjustment or cannot realize arbitrary angle and position adjustment and movement, the present invention provides a multi-angle fracture fixation device that is suitable for any fracture situation. The step-by-step compound adjustment reset device achieves fast and accurate docking of the fracture site, and has a high degree of restraint on the fracture site, so as to facilitate the smooth follow-up surgery on the fracture site

Embodiment 1
[0020] Embodiment 1: as figure 1 In the fracture traction reduction device shown, the proximal steel ring 101 , the adjustment steel ring 201 and the distal steel ring 301 are arranged in parallel in sequence from the inside to the outside. The diameters of the three steel rings are equal, and there are fixing holes and arc-shaped holes distributed on the three steel rings, which are respectively the fixing hole 102 near the steel ring and the arc-shaped hole 103 near the steel ring, the fixing hole 202 of the adjusting ring and the arc-shaped hole 203 of the adjusting ring , the far steel ring fixing hole 302 and the far steel ring arc hole 303.
[0021] It also includes a proximal transversal nail 501, which fixes the broken bone root 901 near the proximal steel ring, that is, as figure 1 The proximal transversal nail is inserted through the root of the broken bone. The near-end transversal nail is connected to the near-end steel ring through a fixing piece, and the fixing...

The invention discloses a fracture traction reduction device, which comprises a proximal end steel ring, a distal end steel ring, an adjusting steel ring between the proximal end steel ring and the distal end steel ring, a proximal end transverse nail and an up-down adjusting nail rod, wherein the proximal end transverse nail is used for fixing a broken bone root, and the up-down adjusting nail rod is used for fixing the distal end of the broken bone; the proximal transverse nail is connected with the proximal steel ring through a fixing piece, so that the proximal steel ring and the broken bone root are fixedly connected together, and the proximal steel ring and the distal steel ring are fixedly connected together through a connecting rod; according to the invention, the functions of standardization and high-precision adjustment can be achieved, the functions of stretching, rotating (turning angle), up-down, left-right translation alignment and resetting and butt joint of fracture positions can be achieved, the stability degree of bone seam butt joint supported by each steel piece is high, and subsequent operation is convenient. The operation is simple and feasible, the accuracy is very high, the operation difficulty and the butt joint inaccuracy are reduced, the simple training is suitable for the operation of doctors at all levels, and the basis is provided for the standardized operation of fracture positioning.
Description
technical field [0001] The invention belongs to the technical field of fracture positioning and fixing devices, and in particular relates to a fracture site reduction device capable of accurately performing multi-step compound adjustment and fixation. Background technique [0002] Femoral shaft fractures and distal femoral fractures are common clinical fractures. Surgical treatment is the preferred treatment method. Before intramedullary nailing and bone plate fixation, the two ends of the fracture site need to be reduced, docked and fixed. Traction is an important means of reducing femoral fractures and restoring the length of lower limbs. At present, the retractors used in various hospitals for lower extremity fracture patients mainly include a traction rope and a pulley. One end of the traction rope is connected to the bracket at the fracture site, and the other end bypasses the pulley to hang weights. The number of weights can be manually increased or replaced. The wei...
