Surgical Instruments For Heating TRIZ Cases

A telescoping tube changes pencil length while a movable suction tip covers more or less of the electrode for smoke and visibility adjustment.

A dome-shaped electrode probe combines electrical ablation and coagulation with pressure transmission for precise prostate tissue enucleation.

Thermistors and switches let TTFields arrays lower current only at overheated elements, preserving field strength elsewhere.

Integrated temperature sensors and impedance feedback adjust radiofrequency power to limit tissue desiccation, reducing stoppages and manual intervention.

A jaw-mounted ultrasonic blade, conductive tissue-contacting surfaces, and an independent slider combine energy treatment with stronger tissue grasping.

Independent electrode-pair control coordinates pulses and adjusts discharge settings for more even, efficient treatment of vascular calcification.

Temperature and impedance feedback enables a radio frequency host to adjust output power as object conditions change, reducing damage risk.

Expandable struts and positioning elements stabilize ablation at the atrial septum, creating a controlled shunt while limiting tissue damage.

Microelectrodes seated in tip apertures acquire tissue signals, while fluid flow around the flexible PCB supports heat exchange during ablation.

Electrical indicator electrodes confirm introducer alignment before RF pericardial puncture, helping limit positioning errors and tissue damage.

A conductive core, insulating collar, and outer region distribute RF current around the tip to limit heat and tissue damage.

Real-time impedance feedback adjusts electrosurgical energy in sequential tissue-fusion stages to reduce adhesion and carbonization.

Basket splines and an inflatable balloon keep electrodes near the vessel wall, reducing movement and energy loss during ablation.

A recessed pusher pocket supports taller staples, improving tissue sealing while keeping the cartridge compact and maneuverable.

Distal balloon electrodes generate shock waves in conductive fluid to cross tight calcified lesions without separate pre-dilatation devices.

A laminated blade, heater, and wiring stack concentrates thermal energy for tissue incision while insulation limits leakage in a thin tool.

Axial electrodes deliver pulsed-field energy to multiple cardiac tissue segments, reducing repositioning and gaps during ablation.

Grouped short electrodes distribute IRE current across a collapsible basket probe, reducing tissue-damage risk during deployment.

Separate smoke and liquid channels evacuate electrosurgical byproducts at the surgical site, reducing smoke exposure for operating-room personnel.

Temperature sensors and impedance feedback adjust up to 100 W per electrode to limit charring and steam popping during short RF ablation sessions.

Non-thermal pulsed electrical fields target tissue for atrial fibrillation treatment while limiting pulmonary vein stenosis and collateral damage.

Segmenting the conductive coil and distal tip preserves distal flexibility while supporting plasma generation and X-ray visibility.

A gaseous refrigerant cools the RF electrode and internal components, reducing burn risk without a separate cooling device.

Thicker insulation near the active electrode limits charge dispersion, while a thinner shaft layer preserves flexibility for bulky device delivery.

Repeated jaw contact can wear the ultrasonic blade; resin jaw and abutment materials help extend its lifespan.

Real-time monitoring of balloon pressure, pulse energy, and treatment conditions lets the controller adjust lithotripsy settings without external devices.

Combining ultrasonic and electrosurgical energy in one end-effector helps tailor tissue sealing and cutting while keeping mode selection simple.

Continuous EEG feedback lets an integrated depth electrode heat the seizure focus while limiting damage to normal brain tissue.

Electrical current passes between the ring and cutting component to create cleaner incisions and simultaneous tissue hemostasis.

Opposed drives maintain tension in flexible actuation members while the compact assembly drives instrument insertion.

A cannula-delivered dissector combines sharp, blunt, electrosurgical cutting, and coagulation to reduce instrument switching.

Separate mechanisms for tissue treatment and cutting can complicate electrosurgical forceps; an integrated jaw member combines both functions for surgical efficiency.

Controlled heat and a passive spreader help this catheter weld vessel walls into a well-aligned AV fistula with less dissection.

Gaussian integrals of propagation vector-fields identify local activation sources and add tags to atrial fibrillation electroanatomic maps.

Serially delivered occluders restrict blood flow in diseased veins, addressing recovery burdens without open surgery.

A flexible catheter tip conforms to tissue while delivering energy and irrigant, supporting controlled lesions and reducing ablation damage.

An electrosurgical forceps detects tissue and sealing completion, then applies thermal energy to cut sealed tissue with fewer treatment steps.

A proximal heat pipe draws excess heat from electrosurgical jaws to cool the end effector and limit thermal spread.

A voltage ramp immobilizes muscles before full IRE pulses, reducing spasms and supporting precise tissue ablation.

Longer jaws can extend the transection stroke; a pinion gear drive converts actuator rotation into lower-force blade travel.

Real-time tissue sensing adjusts RF energy during sealing to limit thermal damage across variable tissue types.
