General Description

Digital Diathermy with Dual Outputs Spark 425 Duo is a multi-functional digital surgical diathermy suitable for both open and endoscopic procedures ranging from paediatric to cardiac surgeries. It has the capability to give two monopolar outputs through hand switch pencils. Specialized functions include soft/spray coag, bipolar cutting, combi mode for laparoscopic surgeries etc. Standard features include inbuilt voltage stabilizer, double handswitched output etc.
