High frequency surgery

High frequency surgery (HF surgery) is an essential technology for both endoscopic and open surgery. Whether in private practices or in clinics – it belongs in many medical fields of application. The selection of monopolar and bipolar devices and instruments is large and RZ offers solutions for devices, instruments and accessories for all endoscopic indications.

The RZ-HF devices G44 and G400 have special setting options for arthroscopy, urology, hysteroscopy and laparoscopic or open surgery.
