Description

External auxiliary reductor for fracture

Technical Field

The utility model relates to the field of medical instruments, in particular to an external auxiliary reductor for fracture.

Background

At present, the closed reduction interlocking intramedullary nail internal fixation is considered as a gold standard and a first choice method for femoral shaft fracture treatment, and the clinical closed reduction femoral shaft fracture can fully solve the problem of limb shortening and displacement by using a traction bed or other traction apparatuses and is widely applied; the lateral displacement of the limb fracture end has no corresponding special tool, although a few scholars introduce some reduction tools or techniques, the repeatability and the operability are not strong, most orthopedists still adopt incision reduction or small incision auxiliary reduction internal fixation to treat femoral shaft fracture, the incision reduction fixation of femoral fracture has a plurality of complications, and simultaneously the pain and the recovery time of patients are increased.

The existing restorer can only help the restoration, but cannot maintain the stability of the fracture end, the fracture end is easy to shift again in the operation, and the repeated restoration increases the injury of the muscle, nerve, blood vessel and other soft tissues of the fracture end. Femoral fracture needs to be fixed by selecting a thicker interlocking intramedullary nail as much as possible so as to improve the fracture fixing strength and the fixing effectiveness, and reaming is often needed; repeated displacement of the fracture end may cause the lead or reamer to break at the fracture end.

The two clamp bodies of the existing reductor can only apply extrusion force to the fracture end on the same plane, so that shear force cannot be provided, the force applied to the fracture end by the reductor can be absorbed by soft tissues such as muscles, and the like, and the fracture end is difficult to effectively reach to obtain a satisfactory reduction effect. The restorer is made of stainless steel materials, and the two forceps clip bodies are mostly positioned at the level of the fracture end, so that X-ray penetration is blocked, and perspective is influenced.
