Description

Technical Field

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

[0002] A high-frequency scalpel, also known as a high-frequency electrosurgery unit, is an electrosurgical device that replaces mechanical scalpels for tissue cutting. It operates based on the principle of a high-frequency electric field, enabling precise control of the cutting and coagulation processes during surgery. The high-frequency, high-voltage current generated by the active electrode tip heats the tissue when it comes into contact with the body, separating and coagulating it, thereby achieving both cutting and hemostasis. High-frequency electrosurgeries are widely used in surgical procedures, primarily for high-frequency cutting and electrocoagulation, offering advantages such as thorough hemostasis and time-saving.

[0003] Existing high-frequency surgical knives can only be used in single surgeries such as surgical or laparoscopic surgeries and have complex structures. To address this problem, we propose a multifunctional high-frequency surgical electrode with interchangeable blades. Utility Model Content
