Canady Hybrid Plasma™ Technology

Canady Hybrid Plasma™ Technology (CHPT) is an advanced electrosurgical energy wave developed for surgery and endoscopy invented and developed by Drs. Jerome Canady & Kimberly Wiley. CHPT is more precise than conventional electrosurgical devices1. USMI’s Microprocessed Electrosurgical Unit / Canady Plasma® Coagulator Argon systems deliver the Canady Hybrid Plasma™ beam that results in the simultaneous cutting and coagulating of biological tissues1.

Since the introduction of CHPT (Mar. 2012), the technology has been successfully used in most surgical subspecialties (i.e. General Surgery, Orthopedic, Neurosurgery, ENT, Plastics, Surgical Oncology, Gynecology, Thoracic & Cardiovascular Surgery). Our data shows that use of CHPT may result in a reduction in intraoperative blood loss and postoperative blood transfusions for orthopedic joint replacements relative to national rates2. For many surgeons using our device, blood transfusion rates have decreased to less than 5% using CHPT2.

What is Canady Hybrid Plasma™ Technology?
Plasma is the most common form of matter in the universe. Considered to be the fourth state of matter, plasma consists of a collection of free moving electrically charged particles of electrons and free radicals. Known plasma gases in the Earth’s atmosphere include He (helium), Xe (xenon), Ar (argon), Ne (neon), Kr (krypton) and Ra (radon).

Canady Hybrid Plasma™ Technology integrates high frequency(HF) monopolar current with an inert plasma gas to deliver a cold plasma beam.

CHPT is delivered via the Canady Hybrid Plasma™ Scalpel. The Canady Hybrid Plasma™ Scalpel is the first smart multifunctional electrosurgical handpiece in the world, incorporating four separate operating modes: Hybrid Plasma Cut, Argon Plasma Coagulation, Conventional Cut and Coagulation.

Surgeons can remotely adjust power setting via the hand piece during surgery. The Canady Hybrid Plasma™ Scalpel can deliver a precise beam less than 1.0mm in diameter and a depth of injury as low as 0.1mm 1.
