Abstract

A knee-joint activity and inertia-combined adjusting control outer fixer comprises an upper C-shaped hole ring arranged at a thighbone far end, and a lower C-shaped hole ring arranged at a tibia near end; the upper C-shaped hole ring is upwards connected with two upper tubular connection rods by a T-shaped connection plate; two dual-groove steel needle fixing clamps are fixed on the two upper tubular connection rods; point ends of two thread semi-needles are fixed on a femoral shaft; an arc arch is connected between the upper C-shaped hole ring and the upper tubular connection rods; the tail ends of the thread semi-needles are fixed with a single-groove steel needle fixing clamp on the arc arch; the point ends of the thread semi-needles are fixed on the femoral shaft. The upper C-shaped hole ring and the lower C-shaped hole ring are connected by a knee elbow joint device. The knee-joint activity and inertia-combined adjusting control outer fixer is firm in static fixing and balanced in dynamic fixing, can adjust and control the kneel joint gap, can promote the fracture healing and reduce or avoid the stiffness of the knee joint and is an advanced and excellent treatment method for the knee joint fracture, particularly the severe comminuted fracture.

Description

technical field [0001] The invention relates to a knee joint bone external fixator. Background technique [0002] In recent years, with the renewal of the concept of external fixation, the improvement of technology and the improvement of instrument functions, new breakthroughs have been made in the treatment of knee fractures with external fixation. While simplifying the operation and improving the curative effect, it provides a new option for the treatment of complex knee fractures, especially severe comminuted fractures and fractures with existing infection. [0003] The concept of external fixation in the treatment of knee joint fractures lies in the treatment principles of phase static fixation and dynamic fixation, distraction fixation and local fixation, fracture treatment and use of the affected limb. For example, the early implementation of static fixation across joints is beneficial to trauma repair and blood supply reconstruction; the mid-term dynamic stretch fixa...
