Surgery TRIZ Cases

A tool holder uses an angled lateral slot and a securing pin to lock a keyed element in place.

Aspheric surfaces on three lenses manage aberrations to deliver wide field of view within compact capsule constraints.

An infra-red projector and camera system tracks dental arch markers to calculate three-dimensional jaw positions.

Segmented base tools and universal mounting resolve the complexity-versus-adaptability contradiction in glenoid bone preparation.

Alternating frame mode scanning with near-infrared light detects veins via differential absorption, reducing time loss during vascular access procedures.

A virtual road mapping system merges pre-acquired CT data with fluoroscope images to create composite vascular views.

Composite guide tube sections prevent shrinkage-induced motion changes to maintain full deflection control in disposable endoscopes.

Automated imaging processor monitors image clarity and commands fluid flow changes to clear surgical site obstructions without manual intervention.

Variable draught angle hexagonal microprojections increase penetration depth and immunogenicity while reducing energy requirements.

A biometric sensor arrangement merges a sensing light source and a flash radiation source into one module controlled by a single driver circuit.

A plate-shaped piezoelectric element bonded to an optical fiber via a conductive electrode.

Wireless docking uses inductive coupling to power and retrieve data from sealed capsule cameras without mechanical contact.

Silk fibroin materials resolve immune response conflicts by maintaining mechanical integrity during rapid volumetric expansion.

Elastic spring arms expand a tissue retrieval bag along perpendicular planes to open the device mouth for sample collection.

A motion detection device analyzes bilateral body movement patterns to identify abnormal states.

An endoscope system generates trail information from position data and superimposes it on three-dimensional luminal organ images for real-time visualization.

An adjustable valve integrated into a hemostasis Y-connector modulates aspiration fluid flow rates during thrombectomy procedures.

A coaxially bonded moisture barrier prevents fluid contact with optical interferograms, maintaining measurement precision during catheter procedures.

A bracing frame expands within a blood vessel to counteract negative pressure from aspiration, preventing radial collapse during thrombectomy.
