Fracture reduction lock nail device

Abstract

The invention discloses a fracture reduction lock nail device. A guide rod is fixedly connected to a base; the guide rod is slidably connected with a first driving part and a second driving part; theupper part of the first driving part is fixedly connected with a rotating supporting part; a moving clamping part is rotationally connected with the rotating supporting part; the lower part of the moving clamping part is connected with a half gear in a sliding manner; the lower part of the half gear is meshed with a rack which moves horizontally; a rotation axis of the half gear and a rotation axis between the moving clamping part and the rotating supporting part are located on the same axis; a middle part which moves vertically is arranged at the upper part of the base; a first connecting rodis arranged between the middle part and the second driving part; the upper part of the first connecting rod is rotationally connected with the middle part; the lower end of the first connecting rod is rotationally connected with the second driving part; and a second connecting rod is arranged between the middle part and the rack. A driving adjustment mode of screw and nut matching is adopted, sothat adjustment is accurate, reduction of a fracture site is accurate and reliable, pain of a patient is relieved, the reduction speed is improved, and the pain of the patient is effectively relieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a fracture reduction locking nail device. Background technique [0002] Fracture reduction methods are usually divided into traction manipulation reduction and surgical open reduction. Traction manipulation reduction usually requires the cooperation of two or three people. If two people are working, the operator distracts the distal part of the fracture and the other assistant distracts the proximal part of the fracture. After a period of traction, the fracture is slightly loosened and the muscles have been relaxed. The operator touches the local fracture end by hand, presses to reset it, and then externally fixes it with a splint or plaster. X-ray films must be checked after reduction. If the alignment of the fracture is found to be good, it is basically ok. However, when more than two people perform fracture reduction, it is difficult to accurately control the movem...

AI Technical Summary

Problems solved by technology

However, when more than two people perform fracture reduction, it is difficult to accurately control the movement of the injured bone during the reduction operation. During the reduction process, it will bring great pain to the patient, and it is difficult to guarantee the effect of reduction.
