Femoral fracture traction apparatus with good reduction fixing effect

Abstract

The invention relates to a femoral fracture traction apparatus with good reduction fixing effect and belongs to the technical field of orthopedic surgical instruments. The femoral fracture traction apparatus is used for traction of femurs in surgeries to recover, adjust and maintain lengths of the femurs effectively. According to the technical scheme, the femoral fracture traction apparatus is composed of a near-end fixing screw, a connecting rod, a traction bow and a fixing needle, wherein a connecting end of the near-end fixing screw is connected with one end of the connecting rod, a rotating structure for adjusting lengths is arranged in the middle of the connecting rod, the other end of the connecting rod is connected with the traction bow, and the traction bow is connected with the fixing needle. According to the femoral fracture traction apparatus, the near-end fixing screw is fixed at the near end of a femur, the fixing needle and the traction bow are fixed at the far end of the femur, the connecting rod is connected in the middle, the distance between the near end and the far end of the femur is adjusted through rotation of the connecting rod so as to reduce shortened fracture, and the length of the femur is maintained and controlled effectively. As a high-effectiveness device in clinical surgeries, the femoral fracture traction apparatus is simple in structure, convenient to use and capable of generating tremendous reduction power and solves the problem of reduction difficulty in femoral fracture surgeries.

Description

technical field [0001] The invention relates to a retractor for intraoperative traction in fracture surgery, belonging to the technical field of orthopedic surgical instruments. Background technique [0002] Femoral shaft fractures and distal femoral fractures are common clinical fractures. Surgical treatment is the treatment of choice, including intramedullary nailing and bone plate fixation. Due to the strong strength of the thigh muscles such as the quadriceps femoris, patients with femur fractures often have shortening deformities due to muscle stretching, and it is difficult to reset, restore their length and maintain them effectively during the operation. If the anatomical reduction cannot be performed during the operation, complications such as malunion and poor alignment of the lower limbs may occur after the operation. In the relevant literature, Winquist et al. reported that 520 cases of femoral shaft fractures were treated with intramedullary nails, and 8% of th...

AI Technical Summary

Problems solved by technology

However, fracture reduction is often unsatisfactory, and two assistants are required to hold the proximal end and the distal end respectively during the operation, which cannot stably maintain the fracture reduction and the length of the lower limbs, which may affect the treatment effect; in addition, the two assistants may occupy the space of the surgeon and affect the surgeon.
