The intense heat produced at the tip of the electromagnetic field focusing (EFF) probe at its point of contact with tissue can cut and vaporize tissue and coagulate blood vessels. As the probe is shaped like a bayonet and has a diameter of 0.3 mm at its tip, it can be used on deep structures through narrow openings, making it ideal for stereotactic craniotomy. Thirteen stereotactic craniotomy procedures using the EFF system were performed. Locations of the lesions were deep in the cerebrum, cerebellum and in the lateral ventricle. The system proved efficient with reduced blood loss and unobstructed view of deep structures. No complications resulted from the use of the system.
电磁场聚焦（EFF）探头与组织接触点产生的强热能够切割、汽化组织并使血管凝固。由于探头形状如同刺刀，尖端直径为0.3毫米，所以可通过狭窄开口用于深部结构，这使其成为立体定向开颅手术的理想选择。使用EFF系统进行了13例立体定向开颅手术。病变部位位于大脑深部、小脑以及侧脑室内。该系统被证明效率高，失血减少，深部结构视野清晰。使用该系统未出现并发症。
