Eye Surgery TRIZ Cases
- Variable Hollow Microneedle Manufacturing via Parameter Control
Hollow microneedles with customizable geometry adapt to specific drug viscosities and skin regions through precise manufacturing parameter adjustments.
- Intraocular Lens Position Prediction Using 3D Interpolation Network
A three-dimensional prediction network interpolates anterior chamber depth and eye length to determine intraocular lens positioning.
- Ocular Fluid Management System with Diaphragm Control
Integrated ocular fluid management system uses diaphragm position control to maintain balanced aspiration and infusion flows.
- External Pressure Measurement for Intraocular Implant IOP Control
Dual-tube sensors measure anterior chamber and atmospheric pressure differentials to regulate valve flow against fibrosis resistance.
- Vitreous Body Cutter With Adjustable Protrusion
Adjustable protrusion length and dynamic bending enable wide opening movement in thin pipes, resolving rigidity constraints.
- Rod Implant Delivery Device With Interlock Mechanism
Handheld delivery device ejects rod implants via plunger and buttons, reducing eye trauma during intravitreal placement.
- Trocar-Cannula Propulsion System with Oblique Entry Positioning
A surgical device uses a triggered propulsion system to drive a trocar-cannula assembly axially through eye tissue.
- Auto Phaco Energy Control for Post-Occlusion Surge Prevention
Learning auto phaco energy control detects aspiration flow deviations to reduce post-occlusion surge risk and eye trauma.
- Ocular Implant Applier Guidewire Depth Metering
A delivery device uses a metered guidewire to position an ocular implant precisely within the eye.
- Integrated Anti-Vacuum Surge Module for Phacoemulsification Handpiece
An integrated anti-vacuum surge module regulates aspiration flow using a solenoid valve and real-time sensor feedback.
- Vitreous Illuminator Angle and Wavelength for Retina Contrast
Segmented illumination uses angled, high-intensity light to make transparent vitreous visible without overexposing the retina.
- Cyclic Aperture Flow Regulator for Surgical Aspiration Surge Control
A cyclic aperture flow regulator system modulates fluid aperture cross-sectional area to stabilize aspiration flow rates during surgical procedures.
- Axial Translation Linkage for Eye Treatment Cassette Alignment
Automated motorized drive applies controlled engagement forces through a mechanical linkage to align cassettes without manual strain.
- Dual Frequency Phacoemulsification Circuit for Cataract Surgery
A dual frequency phacoemulsification circuit switches between low and high frequencies to drive a piezoelectric transducer.
