Surgical Saws TRIZ Cases

Segmented cutting guides with pivotable elements reduce tissue disruption and wound complications during calcaneal osteotomies.

A drill guide system couples to patient-specific alignment guides using matching referencing holes and coupling members to position the device on bone.

A self-clearing surgical saw blade uses radial energy to eject bone chips during cutting.

Progressive punch forming creates a precise pivot boss, and laser welding assembles the blade bar to prevent curvature that degrades cutting accuracy.

A femoral guide wire and elongate element enable precise acetabular reaming through minimal incisions, reducing soft tissue trauma without hip dislocation.

Lateral arms on a spiked head assembly create an access space for cutting blocks, resolving stability versus obstruction trade-offs.

A femur cutting jig uses sparse contact points to position a cut bar plane.

A composite saw blade with a plastic sliding element reduces friction and heat generation during femur resection, extending template service life.

Curved indent geometry on the blade attachment minimizes drive boss wear and prevents slippage during cutting operations.
