Surgical Instruments Using Microwaves TRIZ Cases
- Choked Microwave Antenna for Broadband Tissue Ablation
An unbalanced dipole with a choke, extended dielectric layer, and coolant flow maintains impedance matching as tissue properties change.
- Microstrip Impedance Transformer for Electrosurgical Cable Matching
A planar microstrip transformer matches a 50Ω feed line to a low-impedance electrosurgical cable, cutting reflections, power loss, and heating.
- Magnetic Auto-Alignment Connector for Safe Pogo Pin Coupling
Magnetic alignment guides pogo pins into proper contact and blocks misaligned electrical connection that could damage the microwave generator or instrument.
- DC Block Patient Isolator Absorber Layout for Radiation Suppression
Grounded proximal and distal absorbers around a DC block cut microwave radiation interference and protect remote temperature probe accuracy.
- Internally Cooled Ceramic Radiator for Stable Microwave Ablation
Internal ceramic cooling channels remove heat from a microwave ablation radiator to stabilize dielectric behavior and tissue heating.
- Planar Microwave Ablation Antenna for Bone Growth Plate Heating
A triaxial microwave probe shapes bidirectional planar heating in the bone growth plate to improve growth arrest while reducing pain and complications.
- DC Block Patient Isolator With Split Absorbers for EMI Reduction
A grounded DC block patient isolator uses separated high-loss cavity absorbers to reduce radiation interference and protect sensor accuracy.
