Surgery TRIZ Cases

A percutaneous access system uses a balloon catheter to dilate tissue tracts, reducing angular shearing forces and procedural steps during nephrostomy.

A distal end surface contacts tissue to deliver staining fluid through a channel, enabling super magnified observation.

An endoscope uses a dedicated diaphragm to form an image on the sensor for adapter identification.

An extruded holder merges with the sheath to protect imaging components, reducing outer diameter for easier guide wire insertion.

A hydrophilic copolymer coating forms a cohesive surface layer on medical devices to reduce frictional resistance.

Rotating a sterilization cap opens a bypass path to equalize pressure, preventing damage to flexible components during negative pressure sterilization.

A single-hand endoscope handle unifies shaft and instrument control systems into one interface.

An electromagnetic brake system maintains balance of a flexible endoscope, preventing tip jumping during detachment and reducing repositioning labor.

Neutral beam processing converts drug material into a barrier layer on stents, eliminating polymer delamination and toxicity risks.

Segmented manipulator positioning extends a flexible borescope to inspect confined spacecraft components without impact risk.

An inflatable balloon catheter dislodges embedded vena cava filters from vessel walls, enabling secure helical member compression and safe extraction.

A control device differentiates open and closed field environments to display specific software keys for light emission management.

A medical imaging user interface adjusts focus among graphical elements using handheld device controls to streamline operator interaction.

Elastomeric lens material compresses against tissue to widen the viewing angle while preventing patient trauma from rigid caps.

Actuating lever pivots about an axis to engage locking tracks, amplifying operator input force for easier thoracic surgery access.

A hernia repair patch uses a nitinol support member to expand from a reduced configuration into an expanded state for defect coverage.

Disposable endoscope cover uses a fragile portion to break away from the distal framing portion during removal.

A nested retrieval system extracts uncollapsed filters via a secondary sheath, preventing vessel damage and emboli release.

An optical waveguide interferometer uses an adjustable coupler to set the probe segment gap precisely.

A U-shaped folding frame skin chamber system enables prolonged intravital microscopy observation of subcutaneous tissues.

A radiopaque marker with concentric circles provides direct size comparison on angiographic images.

An endoscope apparatus adds image signals from pixels with overlapping spectral sensitivities to enhance signal-to-noise ratio.
