Laser Surgery TRIZ Cases
- Lateral Canthotomy for Stable Femtosecond Laser Cataract Interface
Lateral canthotomy lengthens the palpebral fissure to overcome suction loss from short fissures and ensure stable docking for femtosecond cataract surgery.
- Spatio-temporal modulator for ophthalmic laser beam distortion
A spatio-temporal modulator applies phase compensation to a surgical laser beam before it enters the eye.
- Corneal Astigmatism Vector Planning via Semi-Meridian Segmentation
Vector summation of weighted topographic zones determines semi-meridian parameters for corneal astigmatism analysis.
- Refracting Element Annular Radiation Profile
Concentric facets in a refracting element produce an annular radiation pattern to counteract heat diffusion and ensure uniform temperature profiles.
- Medical Hollow Needle With Spoon-Like Tip For Cataract Surgery
A medical hollow needle features a spoon-like tip protruding beyond the suction aperture to enhance suction power for cataract removal.
- Electro-Optical Scanning Cells for Multi-Spot Laser Beam Steering
An electrically switchable multi-spot laser probe uses electro-optical materials to steer beams, resolving blurry spot patterns in photocoagulation.
- MIS Robotic Control Terminal Foot-Operated Clutch and Modular Design
Foot-operated clutch breaks signal communication between master and slave manipulators in a modular robotic control terminal.
- Retinal Laser Treatment Using Geometric Boundary Patterns
Geometric laser patterns define retinal treatment boundaries to deliver precise photocoagulation therapy while sparing sensitive macular tissue.
- Steerable Laser Probe With Segmented Housing Tube
Segmenting the housing tube into stiff and flexible portions resolves the trade-off between structural stability and steering ease.
- Microsurgical Instrument Anchoring to Cannula for Flex Control
Segmented instruments anchor to a cannula to prevent flexing, reducing entry wound diameter by up to 66% while maintaining control.
- Capsulorhexis Apparatus Using Ultrasonic Vibration for Precise Capsule Incision
A capsulorhexis apparatus uses high-frequency vibration to incise the anterior capsule with a circular cutting tool.
- Automated Intraocular Pressure Tamponade for Hemorrhage Control
An ophthalmic surgical system uses fundus imaging to detect hemorrhages and automatically adjust intraocular pressure.
- Adjustable Laser Pulse Compressor for Ophthalmic Surgery
A computer-controlled stage moves dispersion components to adjust laser pulse length, eliminating manual delays between surgical phases.
- Intraocular Lens Delivery System Temperature Control
Integrated heater maintains intraocular lens temperature to prevent polymer brittleness and shape loss during delivery.
