Spinal Implants TRIZ Cases

Inserted at minimal disc height, this expandable fusion implant uses screw-driven endplates to restore spacing and stability with less insertion damage.

Preloaded cephalad and caudal anchor blades deploy from a recessed delivery position and lock with cams to simplify spinal fusion insertion.

Deployable anchors lock the interbody fusion implant after insertion, limiting migration while supporting bone ingrowth and long-term stability.

An auto-locking expandable corpectomy spacer enables post-expansion bone graft delivery while maintaining distance from the dura and spinal cord.

A screw-driven linkage lets the interbody implant enter in a compact form, then expand for spinal fusion with less retraction and nerve risk.

A phase-shifted blade mechanism lets an intervertebral cage penetrate cortical bone sequentially, reducing implantation force while securing fixation.

Telescoping rods and an extensible shell let the implanted cage be adjusted non-invasively to match vertebral contours and improve pressure uniformity.

Threaded nested cores and locking mechanisms let a vertebral implant adjust length and endplate orientation for stable spinal support.

Segmented expandable columns let the implant match bony endplates, spread load evenly, and reduce point loading, migration, and bone damage.

Defined wire paths in a retractor blade guide surgical wires through minimally invasive corridors for precise insertion and easier removal.

Vitamin E stabilization and controlled crosslinking reduce UHMWPE spinal implant oxidation while preserving wear and fatigue resistance.

A single-drive spinal spacer expands laterally and vertically to fit minimally invasive insertion while maintaining stable, symmetrical vertebral support.

A modular vertebral implant uses a monolithic spacer body and detachable end plates to cut spacer inventory while preserving fit across spinal cases.

Integrated wire paths in a retractor blade guide stiff surgical wires through narrow spinal corridors, easing insertion and removal while reducing tissue displacement.

Integrated retention spikes deploy from an expandable fusion implant to resist anterior expulsion while allowing height and lordosis adjustment.

Post-insertion expansion increases implant footprint, height, and lordosis to limit subsidence and restore disc spacing and spinal stability.

A posterior projection and retainer ring ease spinal implant screw access in tight anatomy while preventing screw backout and improving fixation.

A variable-diameter helical coil repositions adjacent bones during insertion, then maintains alignment and supports bone fusion.

Sloped endplates and a translation member let one fusion implant expand for better fit, lower manufacturing burden, and improved bone fusion.
