Ear Treatment TRIZ Cases
- Trocar with Measuring Sheath for Tracheoesophageal Puncture Sizing
Integrated trocar and sheath assembly measures puncture length via visible indicia, eliminating separate dilation and sizing devices.
- Tubular Medical Instrument Coupling Mechanism
Rotating clamping claws in a guide track ensure play-free coupling for tubular medical instruments, enabling reliable sterilization.
- Accessory Power Management via Impedance Detection
An electrical conductor injects a test signal to measure impedance for determining connection state.
- Gimbal Mount Introducer Seal Assembly for Varying Instrument Diameters
A gimbal mount enables a resilient seal member to reposition within a housing, accommodating varying instrument diameters while maintaining a fluid-tight seal.
- Active Vibration Noise Control Device Stability
Adaptive notch filter units generate control signals for multiple speakers to cancel vibration noise in vehicles.
- Bio-absorbable Ventilation Tube with Controlled Degradation
A bio-absorbable ventilation tube releases medicament through a degrading polymer matrix.
- Puncture Wire Sheath Ureteroscope Calyx Access
Shielded puncture wire advances through a ureteroscope sheath for direct calyx targeting, eliminating fluoroscopy radiation exposure.
- Phononic Crystal Coupler Acoustic Waveguide Design
A phononic coupler couples sound waves between waveguides using standard and divergent reflectors.
- Tympanic Membrane Tube Delivery System with Automated Incision
Cam-based tympanic membrane tube delivery system automates incision and insertion, reducing scarring and improving tube retention accuracy.
- Intragastric Bag with Mesh Structure and Filler for Obesity Treatment
A mesh intragastric bag filled with dense material reduces stomach capacity, preventing intestinal migration and gastric ulcers.
