In the context of electrosurgery, tissue sticking to the electrode is usually caused by:

In electrosurgery, tissue sticking to the electrode is primarily influenced by the nature of the electrical current being used. When the current intensity is too low, it may not generate sufficient heat to effectively desiccate or vaporize the tissue upon contact. Consequently, the tissue fails to reach a high enough temperature to separate cleanly from the electrode, resulting in tissue adhesion.

The other factors listed, while they can impact surgical results, do not directly relate to the phenomenon of tissue sticking. For instance, using an inappropriate electrode type might affect cutting efficiency or coagulation characteristics, but it primarily relates to the functional aspects of electrosurgery rather than adhesion issues. In contrast, excessive current intensity could lead to tissue charring but would not promote sticking under normal conditions, as a higher energy input generally enhances tissue separation. Lastly, while prolonged contact might contribute to other thermal injuries or complications, it is the insufficient current that is more likely to lead to the problem of adherence.
