| 摘要 |
The ablation device comprises an RF applicator head (2), a main body (4) and a handle (5). The main body includes a shaft (10). The RF applicator head includes an electrode carrier (12) mounted on the distal end of the shaft with an array of electrodes (14) formed on its surface. An RF generator is electrically connected to the electrodes to provide mono-polar or bipolar energy to them. The shaft is hollow and has a suction/insufflation tube (17) having a plurality of holes (17a) extending through it. An arched active spring (19) is connected between the distal end of a passive spring (15), attached to the distal end of the shaft, and the distal end of the tube. The electrode leads extend through the shaft. |
