Abstract
The present invention relates to a surgical system. Specifically, the surgical system comprises a percutaneous and laparoscopic surgical instrument and an electrode-guiding device. The percutaneous and laparoscopic surgical instrument having at least two dry rigid electrodes that are capable of percutaneous insertion to provide non-invasive radiofrequency (RF) therapy on a selected region of organ or tissue. For example, the percutaneous and laparoscopic surgical instrument may be used to ablate tumors from different organs, e.g., breast, colon, lungs, pancreas, prostate, kidney. The percutaneous and laparoscopic surgical instrument can be used in concert with an electrode-guiding device having a main body with insertion holes that correspond to the shape and size of the dry rigid electrodes. The dry rigid electrodes are removably engageable in the insertion holes, which allow the user to manipulate the dry rigid electrodes via the electrode-guiding device during percutaneous insertion and RF therapy.
