Bone traction device

Abstract

The utility model discloses a bone traction device which comprises an orthopedic traction frame body. And the reinforcing assembly comprises a fixing plate, a first spring, a fixing frame and a limiting column. By means of the reinforcing assembly, when the position of the main body support of the orthopedic traction frame needs to be fixed, firstly, under the action of a connecting shaft, a limiting column is adjusted to be in a vertical state, the support is adjusted to the needed position, in the process, a movable column can move in a fixing pipe, and after the support is adjusted, pulling force is applied to a fixing frame, so that the position of the main body support is fixed. According to the scheme, after the fixing frame is stretched to a certain distance under the elastic force effect of the first spring, upward turning force is applied to the limiting columns, the limiting columns are in the horizontal state, the force applied to the fixing frame is cancelled, the limiting columns can bounce into the corresponding limiting holes, and therefore the movable columns are fixed into the fixing pipes. And the connection between the two groups of brackets is increased, so that the brackets are more stably fixed at required positions.

Description

Technical Field
