Eye Surgery TRIZ Cases
- Intraocular Lens Injector With Depth Guard and Plunger Feedback
A depth guard and elastic plunger resistance help place folded intraocular lenses accurately while limiting eye trauma during insertion.
- Ophthalmic Fluid Pump Control With Pressure and Deflection Feedback
Pressure and deflection feedback let linked irrigation and aspiration pumps compensate for component variation and maintain precise surgical fluid control.
- Schlemm's Canal Fluid Delivery with Retraction-Controlled Injection
An ab-interno delivery tool injects viscoelastic fluid into Schlemm's canal during retraction to cut surgery time and tissue disruption.
- Robotic Retinal Grasping Control With OCT Depth Positioning
OCT-guided robotic grasping positions the instrument at a preset retinal distance before closure, reducing misgrasps and retinal damage.
- Intraocular Lens Injector Retainer for Accurate Haptic Tucking
A retainer delays the forward support portion during lens folding, preventing wall interference and reducing manual correction by surgeons.
- Ocular Implant Membrane Design for Sustained Drug Release
A permeable ocular implant delivers drugs directly to target tissue with sustained release while limiting systemic exposure and supporting fluid drainage.
- Permeable Ocular Implant Structure for Sustained Intraocular Drug Delivery
A semi-permeable shell controls drug release inside the eye, extending intraocular delivery while limiting systemic exposure and side effects.
- Swivel Luer Fitting With Curved Flow Path to Reduce Clogging
A curved internal transition and swivel grip help this luer fitting maintain smooth flow, reduce clogging, and ease attachment and release.
- Scleral Fixation Cornea Recovery for Shape-Preserving Excision
Pre-fixating the scleral wall and supporting the cornea with suction reduces distortion, protects endothelial cells, and improves transplant yield.
- Rotatable Eyelid Treatment Tip for Dry Eye Light Delivery
A rotatable cover and disposable tip improve eyelid treatment access while shielding the cornea from direct light exposure.
- Ocular Muscle Hook Assembly for Precise Strabismus Reattachment
Graduated hook translation and scleral clamping improve ocular muscle positioning accuracy in strabismus surgery while reducing operator dependence.
- Phacoemulsification Handpiece Motion Switching to Clear Tip Occlusion
Alternating longitudinal and transverse tip motion clears phaco needle blockages, reducing occlusion and post-occlusion surge during lens emulsification.
- Progressive Cavity Pump Coupling for Disposable Cartridge Reuse
A self-aligning motor-to-rotor coupling lets a disposable progressive cavity pump cartridge be replaced while the motor base is reused.
- Glaucoma Drainage Plate With Coated Channels for Long-Term IOP Control
Coated fluid channels create a sustained aqueous humor drainage path that lowers intraocular pressure and supports long-term glaucoma treatment.
- Magnetically Actuated Glaucoma Shunts for Titratable Aqueous Drainage
Magnetic actuation opens or blocks shunt ports after implantation, enabling precise aqueous drainage adjustment without invasive revision surgery.
- Phaco Probe Resonance Sensing With Magnetic Feedback
Magnetic sensing tracks phaco needle vibration so drive frequency stays at resonance, improving amplitude control and reducing heat-related eye damage.
- Shared Vane Pump for Synchronized Irrigation and Aspiration
A shared vane pump keeps irrigation and aspiration at equal flow rates, cutting ramp-up delay and eye pressure fluctuations in surgery.
- Phacoemulsification Needle Motion to Prevent Lens Capsule Vortices
Alternating needle rotation direction with longitudinal vibration suppresses lens-capsule vortices while maintaining high-power emulsification.
- Wide-Angle Chandelier Illuminator With Scratch-Free Tapered Tip
A ground tapered fiber tip spreads surgical light beyond 100° for stable eye illumination without manual repositioning.
