Eye Surgery TRIZ Cases
- Cataract Removal Handpiece with Dynamic Intraocular Pressure Control
Dynamic irrigation control stabilizes intraocular pressure during high-vacuum cataract extraction, preventing tip occlusions without ultrasound energy.
- Intraocular Surgery Venturi Pump Clogging Prevention
Segmenting aspiration paths into separate tubes prevents nucleus fragment clogging during intraocular surgery, maintaining reliable fluid flow.
- Vitrectomy Apparatus Dynamic Valve Control
A vitrectomy apparatus uses a pressure sensor and controller to dynamically adjust valve timing for precise cutting device operation.
- Microfluidic Valve Boss Relief for Gas Purging
Segmented boss structures enable gas purging from intraocular chambers, resolving reliability issues caused by trapped air.
- Slitted Phacoemulsification Irrigation Sleeve for Surge Control
Slitted irrigation ports in a phacoemulsification sleeve splay open to offset pressure drops from post-occlusion surge, stabilizing anterior chamber pressure.
- Lacrimal-Sinus Implant Conduit for Chronic Sinusitis Treatment
An implant conduit connects the lacrimal apparatus to paranasal sinuses via a created fistula.
- Foot Pedal Programming for Ophthalmic Surgery Settings
Directional treadle movements program ophthalmic surgery settings via a display, eliminating procedure interruptions from manual switching.
- Punctal Plugs for Controlled Drug Release
An osmotic swell plate drives autonomous drug release from a punctal plug, preventing overflow loss in the lacrimal system.
- Surgical System Occlusion Control via Irrigation Flow
A surgical system monitors irrigation pressure and flow rate to detect occlusion stages.
- Surgical Robot Movable Arm Cannula Alignment
A surgical robot aligns a movable arm part with a fixed cannula connection to resolve precision and flexibility trade-offs in minimally invasive procedures.
- Dual-Tube Implant with Biodegradable Inner Core for Glaucoma Pressure Control
Segmented tubes with expandable sections adjust discharge rates to stabilize intraocular pressure and prevent tissue injury during insertion.
- Surgical Flow Limiter Managing Pressure Pulses in Aspiration Branch
Angled subsidiary channels create turbulence to dissipate harmful pressure pulses, preventing intraocular pressure drops during particle breakthrough.
- Trocar-Cannula Insertion with Triggered Propulsion
Triggered propulsion drives trocar-cannula assemblies at controlled velocities, resolving tissue trauma and wound geometry inconsistencies.
- Motorized Conjunctiva Remover for Pigmented Lesion Abrasion
A motorized eye attachment with an oscillating tip mechanically wears down pigmented conjunctiva lesions layer by layer.
