Radiofrequency (RF) plasma surgical electrode

A radiofrequency (RF) plasma surgical electrode, comprising a cable assembly, a proximal handle, a cutter shank and a distal cutter head that are connected in sequence, wherein

• the distal cutter head is internally provided with a first working electrode, a second working electrode and a bendable element;
• the bendable element and the cutter shank form a loop electrode;
• an RF plasma system, the first working electrode and the loop electrode form a first discharge loop;
• and the RF plasma system generates a plasma sheath at the first working electrode to achieve a small-area strong cutting operation;
• the RF plasma system, the second working electrode and the loop electrode form a second discharge loop;
• and the RF plasma system generates a plasma sheath at the second working electrode to achieve a large-area cutting and hemostasis operation;
• and
• the proximal handle is internally provided with an adjustment assembly for adjusting a bending angle of the bendable element in a damping manner;
• the bendable element is internally provided with a cutting type spring tube communicated with the cutter shank;
• and the cutting type spring tube forms a suction hole at an outer edge of the distal cutter head.
