Surgery TRIZ Cases

Chemical modification of polyamides with carboxylic acid groups reduces water absorption while maintaining structural integrity during insertion.

Multi-layer coatings on surgical instruments provide corrosion resistance and distinctive visual identification through vapor deposition.

Sequential biaxial straining aligns polymer chains in semi-crystalline tubes, enabling isotropic mechanical properties that withstand structural loads in vivo.

Deformable spring positions sponge against endoscope lens, preventing fogging and maintaining visualization during surgery.

An automated processor manages histological samples through dedicated treatment stations using integrated handling devices and a cooling unit for embedding material.

A radiolucent anatomical marker features a radiopaque indicator for precise localization over skin targets.

A disposable flexible membrane with reversible adhesiveness protects camera lenses during surgery.

A dedicated rectal overtube vacuum removes stool and sediment independently of the colonoscope channel, preventing clogging and reducing procedural time.

A body fluid testing device integrates a dedicated light source with a magnifying lens group to capture clear sample images for user terminals.

A state-based graphical user interface overlays selectable buttons onto live imaging data within portable non-destructive testing devices.

Information processing apparatus sorts in-vivo images using capsule positional data to organize visual sequences along the digestive tract path.
