Embodiment Construction

[0014] Connect one end of the large sleeve pipe 7 of the 20mm outer diameter 25mm inner diameter 20mm length 200-280mm chute locking rod with a length 180-250mm outer diameter 25mm inner diameter 20mm respectively, and open a diameter 5mm threaded hole 8 at 50mm from the other end. In addition, one end of two small sleeves 5 with an outer diameter of 18 mm and an inner diameter of 10 mm and a length of 200-280 mm is 80 mm long to make a steel bar with a thickness of 8 mm and a width of 18 mm. A central hole 6 with a diameter of 10 mm is opened at the end of the steel bar; A central connecting rod 3 with a diameter of 152mm and 10mm passes through the hole. Weld one end of the small casing 5 of the other two chute locking rods to the central connecting rod 3 . Make 4 screws with a diameter of 5mm and a length of 15mm with plum blossom handles. After the above structure is assembled according to the drawings, a bracket with adjustable angle and length is formed. During the ope...

Abstract

The invention discloses a lower limb interlocking intramedullary nail fixation bracket, which relates to a device convenient for surgical and orthopaedic surgeries. At present, when tibial fracture intramedullary fixation or distal femoral fracture inverted intramedullary fixation surgery is performed, the position of a limb is easy to displace or is compressed so as to affect the surgical operation. The lower limb interlocking intramedullary nail fixing bracket which consists of two same sliding chute locking components (1), a central connecting component (2) and a central fixing belt (3) is placed under the limb which is subjected to human tibial fracture intramedullary nail fixation or distal femoral fracture inverted intramedullary fixation surgery, and the angle and the length of the sliding chute locking rods on the two sides are adjusted, so that the knee joints of human bodies of different heights are maintained at the positions which are bent at an angle of 90 degrees, and further, an intramedullary nail can enter a correct position of a tibia or a femoral medullary cavity at a correct entry point. According to the lower limb interlocking intramedullary nail fixation bracket, individualized treatment can be realized, requirements of different operation patients are met, and meanwhile, the manpower and material resources can be saved to guarantee safe surgery; and the device has the advantages of simple structure, convenience in use, low operation cost and easiness in cleaning and disinfection.

Description

technical field [0001] The invention relates to a device convenient for surgical (orthopedic) operations, in particular to a bracket for tibial intramedullary fixation or femoral intramedullary fixation. Background technique [0002] At present, when performing intramedullary fixation for tibial fractures or inverted intramedullary fixation for femoral shaft fractures, in order to make the knee joint bend 90°, an assistant usually supports the lower femur and continues traction along the opposite direction of the calf, or puts a single Fold the cuboid and place it under the knee joint so that it is flexed 90°. However, it is prone to fatigue if the assistant supports the lower femur and continues to pull it. For example, if the cuboid is placed under the knee joint, it is easy to shift or be compressed. This will make the knee joint gradually lose its 90° flexion position and affect the operation. Contents of the invention [0003] The invention proposes a technical propo...
