    Abstract: The present invention provides a knife head assembly of a novel medical electrotome and a novel medical electrotome. The knife head assembly comprises a snare ring and a cutting knife, the cutting knife comprises a knife handle fixedly connected to a distal end of the snare ring and a knife head fixedly connected to a distal end of the knife handle; the surface of the knife handle is provided with two grooves that are arranged symmetrically and extend in a length direction of the knife handle, the knife handle is further provided with a through-hole penetrating through the knife handle, the two ends of the through-hole are in communication with the two grooves respectively, the distal end of the snare ring is inserted through the through-hole, and the parts of the snare ring on the two sides of the through-hole are limited in the grooves, thus the distal end of the snare ring is embedded and fixed in the knife handle. In the present invention, the snare ring and the cutting knife are mechanically fixed in an embedded manner, and the distal end of the snare ring is inserted and embedded in the knife handle of the cutting knife; the fixed connection structure is stable and reliable, effectively prevents the cutting knife from falling off from the distal end of the snare ring accidentally, and thereby improves the safety of surgical operations.

    Abstract: System and methods of an electrosurgical controller having multiple modes of operation that are configured for treatment of a specific targeted tissue type and the electrosurgical effect desired where the treatment and effect are provided by a single controller and an electrosurgical probe. The electrosurgical controller includes an integrated fluid control apparatus or pump where activation of the controller allows for selective energy delivery and corresponding fluid volume flow rates. The electrosurgical probe includes a fluid transport lumen and is in communication with the controller and the pump for operation of the probe in the various user selected modes with accompanying energy delivery and fluid control directed to the desired treatment and surgical effect.
