energy device
Surgical instruments that use electrical, ultrasonic, or thermal energy for cutting and coagulation.
Full Definition
Energy devices are specialized surgical instruments that utilize various forms of energy—including electrical current, ultrasonic vibration, radiofrequency, or thermal energy—to cut tissue and achieve hemostasis during minimally invasive procedures. Common types include monopolar and bipolar electrocautery, ultrasonic devices (like the Harmonic scalpel), and advanced bipolar systems (such as LigaSure). These devices offer precise tissue manipulation with reduced bleeding compared to cold instruments, but require careful use to avoid thermal injury to surrounding structures. Selection of the appropriate energy device depends on the type of tissue being treated, the desired effect (cutting vs. coagulation), and proximity to critical structures.
Usage
Usage note: Specify the type of energy (ultrasonic, bipolar, etc.) when documenting use.
