Description

Technical Field

[0001] This utility model relates to the technical field of medical device equipment, specifically to a femoral shaft fracture reduction device. Background Technology

[0002] Femoral shaft fractures are a very common type of fracture in trauma orthopedics, accounting for 36.27% of adult femoral fractures, and are most common in young men aged 21-30 and women aged 31-40. Treatment methods include external fixation and internal fixation, with internal fixation being the final treatment. Currently, intramedullary nailing is the primary method of internal fixation. Surgical treatment requires traction of the affected limb to reduce the fracture before inserting the intramedullary nail for fixation. However, during traction, the high tension in the surrounding soft tissues of the femur, coupled with the traction of the proximal femur by the iliopsoas, gluteus medius, and adductor muscles, causes the fracture ends to shift anteromedially or anterolaterally, while the distal gastrocnemius and adductor muscles pull the distal femoral fragment posteriorly or posteromedially. Currently, the procedure involves open incision followed by reduction using a gold finger or intramedullary nail lever to align the fracture ends before inserting the intramedullary nail guide wire. However, this method cannot quickly and accurately align and insert the intramedullary nail guide wire, significantly prolonging the operation time, increasing bleeding, and other risks and complications. Currently, no tools capable of accurate reduction are available for clinical application. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a femoral shaft fracture reduction device that enables rapid external reduction of femoral shaft fractures and facilitates the passage of intramedullary nail guide pins and placement of intramedullary nails.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a femoral shaft fracture reduction device, including a cuboid reduction line, through which a stabilizing arm for stabilizing the long end of the fracture and a reduction arm for reducing the short end of the fracture are provided, wherein the stabilizing arm and the reduction arm are parallel to each other.

[0005] Further: In the above-mentioned femoral shaft fracture reduction device, the stabilizing lever arm includes a straight rod end inserted into the reduction thread and a curved blade-shaped body for stabilizing the long end of the fractured bone.

[0006] The stabilizing lever arm consists of two parallel arms, while the resetting lever arm consists of one arm.

[0007] The two stabilizing arms bend in opposite directions in an embracing manner.

[0008] The straight end of the reset lever is also provided with an L-shaped steering torque. One end of the steering torque is connected to the straight end of the reset lever via a fixed shaft, and the other end is provided with a sleeve handle. The top of the straight end of the reset lever is also provided with a sleeve handle.

[0009] Compared with existing technologies, this utility model of a femoral shaft fracture reduction device includes a cuboid reduction line with a stabilizing arm for stabilizing the long end of the fracture and a reduction arm for reducing the short end of the fracture passing through it. The stabilizing arm and the reduction arm are parallel to each other. This utility model is based on the theoretical foundation of two-point-one-line, three-point-one-plane, and curved-body arc-shaped stability, combined with a three-dimensional spatial structure. Addressing the issue of fracture end displacement due to muscle traction during traction reduction, fracture end reduction can be performed before incision. The purpose is to apply a force in the opposite direction to the fracture end displacement to reduce it, facilitating the passage of the guide pin and insertion of the intramedullary nail. This avoids fracture end reduction after incision, significantly saving surgical time and reducing potential intraoperative and postoperative risks and complications. Through repeated theoretical demonstrations and practical verification, it has been determined that this reduction device can easily, accurately, and quickly complete the required alignment and reduction of fracture ends, solving problems such as difficulty in intraoperative reduction and difficulty in maintaining reduction afterward.

[0013] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] Reference Figure 1 A femoral shaft fracture reduction device, comprising a rectangular reduction liner 1, characterized in that:

[0015] A stabilizing arm 2 for stabilizing the long end of the fractured bone and a reducing arm 3 for reducing the short end of the fractured bone are provided through the reduction thread 1. The stabilizing arm and the reducing arm are parallel to each other. Each stabilizing arm includes a straight rod end inserted into the reduction thread and a curved blade-shaped part for stabilizing the long end of the fractured bone. The reducing arm consists of two parallel stabilizing arms and one single reducing arm. The curved blades of the two stabilizing arms bend in opposite directions in an embracing manner.

[0016] The straight end of the reset lever is also provided with an L-shaped steering torque 4. One end of the steering torque is connected to the straight end of the reset lever via a fixed shaft, and the other end is provided with a sleeve handle 5. The top of the straight end of the reset lever is also provided with a sleeve handle 5.

[0017] Reference Figure 2 When using a femoral shaft fracture reduction device, the two curved bodies of stabilizing lever arm 1 embrace the fractured thigh 6 externally, stabilizing the long end of the fracture. The two points of force application of the two curved bodies of stabilizing lever arm 1 precisely stabilize the long end of the fracture. The curved body of reduction lever arm 2 rests against the short end of the fracture externally. The points of force application of the curved body of reduction lever arm 2 and the two points of force application of the two curved bodies of stabilizing lever arm 2 form the same plane. With the assistance of a C-arm fluoroscopy machine, the short end of the fracture is slowly brought closer to the long end of the fracture by holding the sleeve handle 5, so that the fracture ends are aligned, i.e., the medullary cavities are facing each other. At this time, the intramedullary nail guide pin is inserted through the proximal femur, and the intramedullary nail is placed and fixed. This femoral shaft fracture reduction device greatly saves surgical time and reduces the possible risks and complications during and after surgery.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
