Abstract
An electrosurgical scissors comprising an end effector comprising a first blade member and a second blade member, the first blade member and the second blade member pivotally connected; an electrical connector configured to couple the scissors to a power source; and a fluid passage in fluid communication with at least one fluid outlet.
Claims18
An electrosurgical scissors comprising:
- an end effector (32) comprising a first blade member (34) and a second blade member (36), the first blade member (34) and the second blade member (36) pivotally connected;
- a fluid passage (82) in fluid communication with at least one fluid outlet (120);
- at least one of the first blade member (34) and the second blade member (36) electrically coupled to an electrical connector (68), the electrical connector (68) configured to electrically couple the scissors to a radio frequency power source;
- the first blade member (34) having a first blade member exterior surface (137) and the second blade member (36) having a second blade member exterior surface (139), at least one of the exterior surfaces configured to slide along tissue while the exterior surface is coupled adjacent the tissue with a fluid expelled from the fluid outlet and radio frequency power is provided to the tissue from the scissors;
- and
- whereby the tissue may be sealed from at least one of a flow of bodily fluid and air.

A method for treating tissue comprising:
- providing tissue having a tissue surface;
- providing radio frequency power at a power level;
- providing a fluid at a fluid flow rate;
- providing electrosurgical scissors configured to provide the radio frequency power and the fluid to tissue;
- providing the fluid to the tissue at the tissue surface;
- forming a fluid coupling with the fluid which couples the tissue and the electrosurgical scissors;
- providing the radio frequency power to the tissue;
- sealing the tissue against at least one of a flow of bodily fluid and air from the tissue;
- and
- cutting the sealed tissue with the electrosurgical scissors.
