Abstract
A system includes an energy-based surgical instrument with an end effector having two electrodes. One of the electrodes has multiple electrode portions. A generator coupled to the surgical instrument supplies radio-frequency (RF) energy to an electrode portion for a tissue coagulation process and further supplies RF energy at a higher voltage or current to another electrode portion for a tissue transection process. A control element may monitor tissue impedance or tissue temperature. Other embodiments are described and claimed.
Claims20
A system comprising:
- an energy-based surgical instrument comprising an end effector having a first electrode and a second electrode, wherein the first electrode comprises a first electrode portion and a second electrode portion;
- and
- a generator coupled to the energy-based surgical instrument, wherein the generator is configured to supply a first radio frequency (RF) energy to the first electrode portion for a tissue coagulation process and a second RF energy to the second electrode portion for a tissue transection process, wherein the second RF energy has a higher voltage or a higher current than the first RF energy.
A method for controlling a surgical instrument, the method comprising:
- energizing, by a generator coupled to the surgical instrument, a first electrode portion of a first electrode of an end effector of the surgical instrument with a first radio frequency (RF) energy for a tissue coagulation process;
- and
- energizing, by the generator, a second electrode portion of the first electrode with a second RF energy for a tissue transection process, wherein the second RF energy has a higher voltage or a higher current than the first RF energy.
