Surgery TRIZ Cases

A continuous wire structure varies axial strength to engage and translate obstructions while limiting vascular damage in tortuous anatomy.

Motion and orientation sensors identify the active ultrasound probe, speeding sterile changes and configuring imaging automatically.

Implanted markers and probe-based electromagnetic sensing create a 3D body model to guide lesion removal and preserve healthy tissue.

Passive RFID tags identify devices for console-based tracking, calibration, inventory, and procedural compliance monitoring.

A spring arm and mechanical barrier protect VAD cuff locks during seating, helping prevent damage and pump replacement.

Sewn gripping filaments create textured graft surfaces that anchor irregular tissue while supporting compliance.

A covalently linked alkylsilanyl base coat and hydrophilic top coat improve durability and lubricity while reducing particulate shedding.

A bracket and extension clip secure surgical instruments to tubular retractors, preserving access space and helping prevent tissue blockage.

An accelerometer and light sensor detect toileting context, capturing contemporaneous stool frequency data for app-based monitoring.

Segmented shafts, seals, caps, and a resilient member simplify disposable valve assembly without adhesive or welded joints.

Disengaging and collecting zones work with a movable macerator to fragment thrombus and improve transport through the catheter lumen.

This case adjusts emitter and phosphor thickness with a light distribution lens to align emission directions and improve image uniformity.

A movable locking feature secures dilator connections across therapy sheath hubs with varying inner diameters.

A resealable guide catheter and aspiration enable repeated clot-removal passes without repeated catheter insertion.

Adaptive heartbeat monitoring detects disconnections and triggers fail-safe signals.

Historical 3D and 2D images train an AI model to match projections, reducing alignment errors and processing time during operations.

A modular robotic endoscope uses nested flexures to support pull wires, improve maneuverability, and enable single-use operation.

The console detects harmonic signals and creates a phase-shifted cancellation signal for cleaner drive and lower tool stress.

This endoscope case uses a nested, flexibly bendable bracket to support axial force and limit tube bending during insertion.

A two-plate mesher aligns slots with recesses to create repeatable skin graft slits and simplify cleaning in resource-limited settings.

This case pairs a rolling shutter imager with a liquid crystal shutter to block visible light while capturing fluorescence data.

This case uses a soluble carbohydrate coating to protect medical contact surfaces from contamination and strain while preserving hydration.

Side jet channels distribute cleaning fluid around the tip, while compact camera and tool layouts expand viewing and surgical access.

Movable control-wheel protrusions adjust the effective radius, reducing operating force and strain during prolonged endoscopic procedures.

Aerosol-deposited composite layers improve implant strength and durability while enabling sustained bioactive ingredient release.
