Eye Surgery TRIZ Cases

Vacuum pulsing devices alternate pressure cycles to draw tissue into a hollow needle, reducing thermal damage during cataract surgery.

A scleral implant lumen channels aqueous humor to the tear film while preventing bacterial ingress through precise geometric design.

Roughened forceps jaws scrape and grasp internal limiting membrane tissue, eliminating instrument exchanges that increase surgical time and tissue trauma.

A handheld ultrasonic device with a concave tip targets the eye to dislodge debris.

A Starling resistor implant uses a spring-loaded deformable structure to self-regulate intraocular fluid flow.

Electronic positional detection systems enable preoperative marking accuracy, resolving trade-offs between patient flow efficiency and ink mark durability.

A punctal plug featuring a cone-shaped anchor secures placement within the lacrimal canaliculus to retain therapeutic agents.

A rotating abrasive medical device creates precise channels in soft tissue using friction-based material removal.

A removable lacrimal implant inserts into the canaliculus to hold tear fluid and release therapeutic agents locally.

Segmented shaft design uses flexibility slots to navigate curved tissue while an observation window maintains clear implant visibility.

Segmenting suction and ultrasound functions protects the posterior capsule from rupture during cataract surgery.

A surgical contact lens integrates an anti-fogging device delivering thermal energy to the optical surface.
