Automatic reduction device for distal radius fracture

Abstract

The invention discloses an automatic reduction device for distal radius fracture. The automatic reduction device comprises a movable base, a lifting type arm fixing bearing table, a lifting type supporting table, a horizontal moving type traction pressing mechanism and a horizontal moving type traction palm flexion angle adjusting table; the bottom end of the lifting type arm fixing bearing table is fixedly connected with one side of the top end of the movable base; the bottom end of the lifting type supporting table is fixedly connected with the other side of the top end of the movable base; the bottom end of the horizontal moving type traction pressing mechanism is slidably connected with the top end of the lifting type supporting table through a first driving mechanism in the traction direction, an arc-shaped sliding rail is arranged at the top of the horizontal moving type traction pressing mechanism, and a plurality of pressing correction push rod mechanisms are slidably connected to the arc-shaped sliding rail; a pressure sensing probe is fixed at the pressing end of each pressing correction push rod mechanism; the bottom end of the horizontal moving type traction palm flexion angle adjusting table is in sliding connection with the bottom of the horizontal moving type traction pressing mechanism through a second driving mechanism in the traction direction, and the top end of the horizontal moving type traction palm flexion angle adjusting table is connected with the top end of the lifting type arm fixing bearing table. The device is simple in structure, high in safety and capable of achieving accurate traction reset.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic restoration device for distal radius fractures. Background technique [0002] Distal radius fractures are one of the most common fractures in the emergency department, mostly in middle-aged and elderly women. The mechanism of injury is often when the hand is stretched to support the ground when falling, resulting in the concentration of violence on the cancellous bone of the distal radius and causing a fracture. Epidemiological studies have shown that with the aging of the population and changes in people's lifestyles, the incidence of distal radius fractures continues to increase. At the same time, severe weather and environment will increase the risk of accidents. [0003] For most fractures of the distal radius, especially the common extension fractures (Colles fractures), it can be treated by traditional Chinese medicine orthopedic techniques combined...

Problems solved by technology

The fracture reduction mechanism designed by it has poor controllability and poor precision, and cannot satisfy the reduction of distal radius fractures.
