External Osteosynthesis TRIZ Cases

Cylindrical guide mechanism eliminates dirt accumulation in dovetail sections while enabling precise clamp adjustment.

Repelling permanent magnets separate bone portions, reducing structural complexity and load on damaged cartilage.

Nested actuation improves adjustment precision while minimizing device complexity.

Mobile jaws disengage from a threaded rod for acute adjustment while a protective band prevents accidental changes.

A bone fixation device uses a curvilinear guide and screw mechanism to adjust joint angles.

A Y-frame external bone fixator with adjustable arms and mounting hardware enables precise translational and rotational positioning of fixation pins.

A dynamic mini-rail system with a telescoping body and clamping portions allows independent adjustment of fixation pin orientation.

A connecting device for external fixators uses rotatable clamping arrangements and a tensioning element to lock angular positions.

A ball joint system uses radial displacement of wedge surfaces to lock a telescopic rod inside an external fixator ring hole.

Perpendicular block channels enable rapid needle and rod assembly, eliminating bulky cement handling in confined spaces.

Pre-assembled external fixation systems use one-way locking mechanisms to maintain limb length during stabilization, reducing intraoperative assembly time.

Composite frames with cam locks replace heavy metal screws, reducing X-ray opacity and enabling precise radial alignment of wires.

Aligned connection pin holes in segmented clamps reduce device volume, allowing more screws on the rail to correct bone deformations.

Contoured fixator segments eliminate obstructive halo rings and support blocks to improve X-ray visibility and pin accuracy.

A self-aligning elbow fixation device uses arched and linear slots with locking mechanisms to define the articulation axis.
