Eye Surgery TRIZ Cases
- Periocular Suture Anchor for Adjustable Eye Immobilization
An adhesive periocular anchor with a rotatable suture fastener stabilizes extreme gaze positioning and reduces slippage during eye surgery.
- 3D Endoscope Position Mapping for Vitreous Surgery
A 3D eyeball map tracks endoscope position during vitreous surgery, helping avoid instrument interference and retina damage.
- Integrated Syringe Handling Tool to Reduce Cataract Surgery Astigmatism
Combining viscoelastic injection and handling in one surgical tool avoids repeated insertion, helping reduce astigmatism and surgery time.
- Cross-Blade Surgical Scissors for Circular Lens Capsule Incision
Crossing blades cut perpendicular to the entry path, helping form a circular anterior capsule incision and prevent artificial lens misalignment.
- Glaucoma Drainage Tube With Positioning Wings for Stable Implant Placement
Positioning wings, a marker, and a curved tube help place glaucoma implants accurately, stabilize fixation, and reduce corneal damage.
- Disposable Tissue Removal Probe With Separated Motor Drive
A disposable probe with a separate motor improves sterility, ergonomics, and activation safety for precise tissue removal in sensitive organs.
- Negative-Pressure Specimen Collection Valve for Precise Fluid Sampling
A negative-pressure reservoir and controllable valve enable minimally invasive liquid specimen collection with better volume control and less transfer loss.
- Phaco Tip Detection Using Pressure and Resonance Signals
Pressure differential and resonance sensing identify the phaco tip in use, preventing setting mismatches and improving surgical safety.
- Capsulotomy Loop Deployment for Precise Circular Lens Incisions
An elastic conductive loop deploys through a corneal guide to cut a consistent circular lens capsule opening with less tissue damage.
- Punctal Plug Structure for Sustained Ocular Drug Delivery
An angled punctal plug enables targeted, sustained ocular drug release while reducing frequent eye-drop dosing and systemic side effects.
- Schlemm's Canal Excision Tool for Circumferential Meshwork Removal
A pull-string excision tool removes trabecular meshwork around Schlemm's canal to improve drainage and limit scarring-related reclosure.
- Ocular Implant Membrane Design for Sustained Intraocular Drug Delivery
A permeable ocular implant enables sustained intraocular drug release and aqueous humor drainage to treat glaucoma with fewer side effects.
- Arcuate Eye Outflow Scaffold for Glaucoma IOP Regulation
An arcuate scaffold supports the trabecular meshwork and Schlemm's canal to reduce outflow resistance and help regulate glaucoma IOP.
- Schlemm's Canal Guide and Blunt Engager for Trabecular Removal
A blunt tissue engager and superelastic shaft remove trabecular meshwork continuously while reducing bleeding, tissue damage, and complex canal tracking.
- Ocular Implant Delivery Wheel Mechanism for Precise Low-Friction Pushing
A rack-and-pinion wheel drives push and retraction linkages to improve ocular implant placement accuracy while reducing friction loss.
- Punching Iridotomy Instrument for Precise Iris Incision Control
A fork-guided punching mechanism improves iris hole size and position control, shortening iridectomy time and reducing hemorrhage risk.
- Biodegradable Inner Tube for Adaptive Aqueous Humor Drainage
A biodegradable inner tube widens over healing time, balancing early hypotonia risk with long-term intraocular pressure control.
- Anchored Glaucoma Shunt for Minimally Invasive Pressure Relief
A lumen shunt with umbrella support and anchors drains aqueous humour to lower intraocular pressure while limiting migration and surgical trauma.
- Surgical Microscope Illumination Layout for Reflection Reduction
Multiple offset light sources improve surgical view clarity while reducing reflections and light-induced patient discomfort.
- Adjustable Shunt Flow Control With Flexible Membrane Sealing
A movable sealing assembly and flexible membrane let shunts tune flow resistance after manufacture while improving aperture sealing.
- Intraocular Drainage Flap Structure for Pressure-Responsive Flow
A pressure-opened flap and rigid plate create controlled aqueous humor drainage, while microgrooves support tissue integration over time.
- Flexible Polymer Grasper for Retinal Membrane Peeling
Flexible angled polymer arms enable controlled retinal membrane grasping and peeling while reducing puncture risk from excessive force.
- Adjustable Ocular Drainage Valve for Stable Intraocular Pressure
A rotatable disk compresses a deformable tube to non-invasively tune drainage resistance and avoid hypotony, over-drainage, and clogging.
- Vitreous Cutter Safety Net for Retina-Protected Tissue Removal
A distal safety net lets vitreous pass but blocks retina tissue, enabling close suction cutting with lower risk of bleeding and detachment.
