Rapid restorer for treating fracture of long tubular bones of limbs

Abstract

The invention discloses a rapid restorer for treating fracture of long tubular bones of limbs, and belongs to the technical field of bone surgery instruments. The rapid restorer is used for pulling fractured thighbones such as the long tubular bones of the limbs, so that the thighbones are restored. The technical scheme includes that a restoring support of the restorer comprises four supporting legs and a square frame, a traction screw rod is screwed into a screw hole in a rear cross rod of the square frame, the front end of the traction screw rod is connected with the upper end of a traction bow, the lower end of the traction bow is connected with a traction needle, a front cross rod of the square frame is connected with the rear end of a fixing rod, and the front end of the fixing rod is connected with a fixing needle. The restoring support of the restorer is placed at a near end of each long tubular bone, the front end of the fixing rod is connected with the near end of each long tubular bone or adjacent trunk bones, the traction screw rod is rotated to pull the pulled long tubular bones, so that shortened fractured bones are restored, and the lengths of the bones are effectively maintained and controlled. The rapid restorer is simple in structure and convenient to use, huge restoring strength can be generated, the problem of difficult restoring in the fracture surgery of the long tubular bones is solved, and the rapid restorer is an instrument with high effectiveness in the clinical surgery.

Description

Technical field [0001] The invention relates to a reducer for traction on long tubular bone fractures of extremities in fracture surgery, and belongs to the technical field of orthopedic surgical instruments. Background technique [0002] Femur, tibia, humerus and other long tubular bone shaft fractures and distal long tubular bone fractures are common clinical fractures. Surgical treatment is the preferred treatment method, including intramedullary nail fixation and bone plate fixation. Taking femoral fractures as an example, due to the strong strength of thigh muscles such as the quadriceps femoris, patients with femoral fractures often have shortening deformities due to muscle traction, and it is difficult to reduce, restore their length and maintain their length effectively. If anatomical reduction is not possible during the operation, complications such as malunion and poor lower limbs may occur after the operation. In the relevant literature, Winquist et al. reported that...

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.
