Diagnostics TRIZ Cases
- Orthopedic Depth Measurement Device Using Nested Tracer System
Nested components and a tracer system resolve the contradiction between measurement precision and device complexity in orthopedic grinding operations.
- Electrosurgical Forceps Pivot Assembly for Consistent Clamping Pressure
A resilient pivot assembly compresses radially to maintain precise clamping pressure between jaw members during electrosurgical procedures.
- Ultrasonic Dissection System End-Tone Feedback Module
End-tone outcome indicator module uses data look-up tables to provide specific tissue treatment feedback, eliminating reliance on subjective visual observation.
- Surgical End Effector with Dual Electrodes for Tissue Sealing
Dual electrodes in a surgical end effector apply heat at different jaw positions to seal tissues of varying thickness without burning.
- Adapter Locking Mechanism for Hollow Body Internal Rinsing
Dynamic locking mechanism secures hollow body connections under pressure while minimizing rinsing shadows and simplifying handling.
- Rotating Actuator for Deploying Implant Wings
A rotating actuator system deploys implant wings through controlled axial guide wire movement.
- Vertebral Endplate Processing Device with Synchronized Expansion
A vertebral endplate processing device integrates vertical opening and horizontal expansion mechanisms for simultaneous surgical action.
- Drill Guide Assembly with Navigation Tracking for Surgical Precision
Navigation processor displays real-time tool position relative to patient anatomy, resolving visual control loss during hidden-tip drilling.
- Disposable Electrode Assembly for Vessel Sealing
Disposable handswitch assembly uses fixed stop members to control electrode gap, ensuring consistent pressure for reliable vessel sealing.
- Fluid-Filled Compressible Cushion for Face Mask Sealing
A face mask uses fluid-filled compressible cushions to adapt to facial contours and create a secure perimeter seal.
- Surgical Drape with Chevron Fenestration for Anatomical Positioning
A surgical drape uses a chevron-shaped fenestration to identify anatomical points of interest during procedures.
- Capacitive Return Electrode Connection for Electrosurgical Safety
A capacitive electrical connection system replaces mechanical plugs in electrosurgical return electrodes to enable flexible positioning.
- Surgical Stapling Device Thermal Management
Thermal energy storage members in the rotation knob evaporate residual water, preventing moisture damage to internal electronics.
- Beltless Staple Chain for Continuous Surgical Staplers
A beltless staple chain uses frangible connections and lateral support elements to deploy staples sequentially without feeder belts.
