Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a high-frequency surgical electrode. Background Art

[0002] With the advancement of medicine, different medical devices are used in different scenarios. Medical high-frequency electrosurgeries, which utilize arc discharge and heat generated by the blade tip to cut tissue and stop bleeding, are essential tools in surgery. However, areas such as the ear, nose, and throat are deep and confined. While the length of currently used electrosurgeries meets these requirements, they are often linear, which limits the surgeon's field of view. Furthermore, the smoke and bleeding generated by the electrosurgery in the surgical area can easily obscure the surgeon's field of view. Furthermore, during surgery, excessively high temperatures in high-frequency electrosurgeries can cause blood and soft tissue to dehydrate, scab, and even char, which can adhere to and coat the blade tip, severely impacting the surgical process and the effectiveness of the treatment.
