BIPOLAR diathermy

The OS 4 is equipped with the bipolar diathermy technology that can be flexibly used for various applications. With the appropriate tip, different procedures can be performed, including standard diathermy, endo-diathermy, Oertli capsulotomy for performing capsulorhexis, and the HFDS procedure for treating open-angle glaucoma.

Thanks to the simple plug-in principle, the tips can be easily exchanged on the handpiece. Both the handpiece and the tips are made of high-quality titanium and can be sustainably reused[1].

The technology of bipolar diathermy creates a precise and localized effect, leaving the adjacent tissue undamaged.
