Surgery TRIZ Cases
- Capsule Endoscope Dynamic Frame Rate Control via Sensor-Image Fusion
A capsule endoscope control unit switches imaging modes using combined sensor and image analysis to adjust frame rates.
- Autonomic Nervous System Monitoring via Skin Conductance Integration
Control unit calculates integral values from skin conductance signals to output a single measure of the autonomous nervous system state.
- Endoscopic Reflection Microscope Phase Retardation Compensation
An endoscopic reflection microscope establishes a reflection matrix to compensate for phase retardation in optical fiber bundles.
- Protein-Based Hydrogels for 3D Printing Biodegradable Parts
Tannic acid treatment and thermal curing enhance mechanical strength of biodegradable protein-based hydrogels for 3D printing.
- Micro-graft Matrix Device Using Hollow Cylindrical Skin Punching
A device set with adhesive films and hollow cylindrical punches creates a micro-graft matrix from full-thickness skin for transplantation.
- Vena Cava Filter Retrieval Device with Strut Engagement
A retrieval device uses a strut engaging member and deployable loop to secure vascular filters for removal.
- Endoscope Cleaning Apparatus Position Detection
Stepped portions on the chemical bottle enable limit switch detection of insertion positions, preventing leakage without increasing device complexity.
- Endoscope Spectral Separation Inversion
Inverting standard spectral separation, a dichroic filter transmits specific return light and reflects normal return light to eliminate noise mixing.
- Ophthalmic Speculum Probe Guiding Cavity Alignment
A probe guiding frame with spaced peaks creates a cavity that directs the lens probe to the cornea.
- FAMMISS OCT Merging Multiple Spatial Samplings for Blood Flow Speed
The FAMMISS method merges multiple integrated spatial samplings to generate composite images with detailed blood flow speed information.
- Flexible Dermabrasion Hand Piece with Articulated Head
A dermabrasion hand piece uses a flexible treatment head and elastic rim to seal against curved skin surfaces.
- Hysteroscope Re-configurable Distal Channel for Tool Introduction
A hysteroscope shaft features a re-configurable distal channel that expands to accommodate larger interventional tools.
- Touchpad Controller Interface for Catheter Lab IVUS Systems
A segmented touchpad controller interface enables intuitive tactile operation of intravascular ultrasound systems.
- Sensor Insertion Device Quiet Needle Withdrawal Mechanism
Rotating arm mechanism quietly extracts guide needle without spring force, eliminating loud snapping noise that causes patient discomfort.
- Vascular Anastomotic Coupling Device Using Non-Penetrating Clamping
A vascular anastomotic coupling device uses inner and outer rings to trap everted vessel portions for secure joining.
- Capsule Endoscope Light Emission Control for Lesion Imaging
Capsule endoscope modules synchronize light emission with imaging direction to illuminate specific areas.
- Surface-Modified Magnesium Alloy Dual-Layer Coating
A surface-modified magnesium alloy applies a dual-layer coating to resolve the trade-off between corrosion resistance and mechanical strength.
