Laser Surgery TRIZ Cases
- Laser Focus Position Determination via Measurement Marking Scanning
Scans reference area markings to determine laser focus position, eliminating mechanical focusing movements and reducing metrological effort.
- Laser-Surgical Apparatus Stray Light Suppression via Digital Image Manipulation
Electronic image manipulation suppresses laser stray light in surgical apparatuses, preventing overexposure and color falsification without mechanical filters.
- Virtual Aperture Intraocular Lens for Aberration Correction
A virtual aperture scatters optical rays across the retina to reduce monochromatic and chromatic aberrations in intraocular lenses.
- Multifunction Surgical Footswitch for Ophthalmic Laser Control
Integrating standby and firing switches into one footswitch allows surgeons to control laser states independently, eliminating assistant dependency.
- Self-Sealing Trabeculectomy Eliminates Scleral Flap Suturing
A self-sealing scleral flap design replaces traditional sutures in trabeculectomy procedures to maintain filtration channel integrity.
- Refractive Surgery Treatment Table Validation via Simulation
A validation system compares intended optical refractions with expected values derived from simulated ablation profiles to qualify treatment tables.
- Adjustable Illumination Aperture Vitrectomy Cutter
An illuminated vitrectomy cutter uses a movable light sleeve to adjust the illumination aperture, eliminating separate probes and adapting to surgical needs.
- Ophthalmic Probe Tip Assembly with Nitinol Guiding Member
A probe tip assembly uses a nitinol guiding member and straightening tube to steer laser beams within the eye.
- Ophthalmic Laser Focal Point Adjustment via Temperature Feedback
Temperature feedback compensates for thermal expansion and manufacturing tolerances in ophthalmic laser surgery apparatus.
- Corneal Lenticule Side Tab for Laser Extraction
A laser system forms a corneal lenticule with a protruding side tab to enable direct instrument grasping.
- Combined Femtolaser-Phacoemulsification Surgical System
Integrated surgical device merges femtolaser ablation with phacoemulsification to eliminate patient translocation and reduce procedure time.
- Replaceable Optic Fiber Laser Probe for Ophthalmic Surgery
Segmenting the laser probe into reusable handles and disposable optic fibers reduces ophthalmic treatment costs while maintaining surgical sterility.
- Intraocular Lens Tilt Compensation via OCT and Movable Fixation Target
Align intraocular lens transverse planes perpendicular to the ophthalmic system axis with a movable fixation target, enabling precise laser power adjustments.
- Corneal Access Incision Valve Flap Sealing
Segmented laser incisions form a wedge-shaped valve flap that maintains wound closure and prevents aqueous humor drainage under external pressure.
- Steerable Laser Probe Shape Memory Sleeve Actuation
A steerable laser probe curves an optic fiber via a shape memory sleeve, enabling multi-location targeting in the eye without complex mechanical linkages.
- Femtosecond Laser Corneal Incision with Asymmetric Convex Geometry
Asymmetric convex geometry suppresses incision drawing and enables self-closing during intraocular lens insertion.
