The forceps can also include a securing mechanism that secures the removable heat pipes to the device.
Claims20
Electrosurgery forceps comprising:
- an electrical connector;
- a pair of flexible tines extending from the connector;
- an electrode at the end of each tine;
- and
- a heat pipe within each tine, the heat pipe having a sealed internal cavity which contains a heat transfer fluid to dissipate heat from the electrode.
2 more elements
A method for applying energy to tissue comprising:
- providing a bipolar electrosurgical forceps having a first electrode having a first polarity and a second electrode having a second polarity, a first time having a first heat pipe attached to the first electrode and a second tine having a second heat pipe attached to the second electrode, the heat pipes having a sealed internal cavity containing a heat transfer fluid for conducting heat from a surgical site;
- attaching the forceps to a power source;
- grasping tissue between the first electrode and the second electrode by compressing the tines;
- and
- driving energy from the first electrode to the second electrode.
