Laser Surgery TRIZ Cases
- Femtosecond Laser Ophthalmic Surgery Docking Cone Image Processing
Processor generates real-time histograms of suction cone position to replace visual inspection and reduce placement errors.
- Corneal Deformation Compensation in Laser Eye Surgery Control
A control method adjusts laser target coordinates to account for corneal deformation caused by contact glass pressure during eye surgery.
- Hollow Needle Applicator for Plasma-Induced Cell Treatment
A hollow needle applicator generates pressure pulses via laser-induced plasma to remove epithelial cells from the lens capsular bag.
- Retractable Thermal Capsulotomy Tool for Stable Lens Opening
Segmented thermal incisions and nested instrument design resolve trade-offs between surgical precision and structural stability during cataract procedures.
- Small Diameter Fragmatome for Minimally Traumatic Lens Fragment Removal
Miniaturizing the fragmatome to 23-gauge eliminates large incisions and suturing, reducing patient trauma while maintaining complete fragment removal.
- Deformable Dispersive Mirror for Ultra-Short Pulse Dispersion Compensation
A deformable dispersive mirror adjusts its shape to compensate for spatial variations in group delay across a scanning optical system.
- Single-Piece Ophthalmic Patient Interface with Magnetic Coupling
A single-piece patient interface device integrates a hollow shell, applanation lens, and flexible skirt for ophthalmic laser surgery.
- Laser Immunotherapy Immune Privilege Modification
Short-duration high-power pulses modify immune privilege status in pigmented epithelium, eliciting beneficial immune response without lasting tissue damage.
- Segmented Suction Ring for Corneal Tissue Imaging
Transparent segments in the suction ring allow SHG and THG detection, resolving vacuum sealing conflicts.
- Automatic Patient Positioning in Laser Eye Surgery
A closed-loop video system positions the patient relative to a camera objective, enabling accurate astigmatic axis determination without manual intervention.
