More Complete Ablation over a Wider Area
Cleaner tumor removal
WKnife is the world’s first steep-pulse treatment system capable of treatment under local anesthesia using a single local-anesthesia needle and bipolar catheter. It is also the first NanoKnife system to achieve “single-needle ablation + local-anesthesia operation” while covering both liver and pancreatic indications. These international breakthroughs establish a new benchmark in tumor ablation and mark the beginning of the local-anesthesia era for NanoKnife tumor ablation.
WKnife’s unique local-anesthesia and single-needle technology transforms the treatment experience
| General Anesthesia | Local Anesthesia |
|---|---|
| Requires tracheal intubation and ventilator support | No tracheal intubation; the patient breathes independently |
| Unconscious during surgery, with a risk of postoperative nausea and vomiting | Awake and pain-free throughout the procedure, with real-time patient feedback |
| The procedure may take several hours | Treatment time shortened to 15 minutes |
| Hospital stay of 1–2 weeks or longer | Discharge in as little as 3 days |
| Long recovery and greater physical burden | Fast recovery with little impact on daily life |
| Requires strong cardiopulmonary function and may not be tolerated by some patients | Suitable for older patients and those with impaired cardiopulmonary function |
Primary and metastatic liver cancer, especially lesions in high-risk locations and cases unsuitable for surgery
For pancreatic cancer, known as the “king of cancers,” WKnife can reach areas considered unsuitable for surgery
For prostate cancer and recurrent disease, WKnife precisely ablates tumors while protecting the urethra and erectile nerves.
Early-stage lung cancer and lung metastases in patients unable to tolerate surgery or general anesthesia
“Cosmetic” precision tumor inactivation that improves cosmetic satisfaction and quality of life
Renal masses and metastatic kidney tumors in patients who prioritize preserving kidney function
Retroperitoneal and extremity soft-tissue metastases
