Surgical Instruments For Heating TRIZ Cases
- Cooled RF Probes With Heat Transfer Without Peristaltic Pumps
Integrated probe cooling removes heat without peristaltic pumps, improving stability.
- Sequential Electrode-Pair Activation for Low-Heat IRE Ablation
A processor-controlled sequence alternates catheter electrode pairs to extend IRE coverage while limiting electrode and tissue heating.
- Bipolar-Monopolar Electrosurgical End Effector for Thermal Spread Control
A multi-electrode end effector switches energy paths between bipolar and monopolar modes to improve cutting while limiting thermal spread.
- Recessed-Electrode Electrosurgical Instrument for Tissue Sealing
Insulating grip faces recess and align electrodes, avoiding spacers that can perforate tissue or create coagulation shadows.
- Ultrasonic Cardiac Ablation With Periodic Power Control
High-power ultrasonic heating followed by low or zero power limits heat conduction into nearby collateral tissue.
- Electrosurgical RF Control Using Impedance-Based Vaporization Detection
An RF generator uses impedance feedback to detect vaporization and adjust energy delivery for controlled depth with less tissue damage.
- Periodic Pulsed Electric Field Therapy for Tumor Ablation and Immune Response
Controlled pulse timing reduces cavitation and thermal effects while tumor antigen release supports CD8+/CD4+ immune activation.
- Sealer, Divider and Dissector Jaws with Insulated Core-Support Separation
Insulated gaps separate conductive jaw members, helping limit electrical shorts and material fatigue during prolonged sealing and cutting.
