Further, also comprise the second fixed block be set on all ablation needles, described second fixed block is relative with each ablation needle fixing.
Because the part that ablation needle stretches out needle handle is longer, ablation needle rigidity is less, can fix each ablation needle preferably, preventing ablation needle from relatively bending or tilting by arranging the second fixed block, thus ensures the reliable also steady operation of ablation needle.
Further, also comprise and be set on all ablation needles, the second fixed block be slidably matched with each ablation needle, have a spacing line between described second fixed block and needle handle, the length after described spacing line is stretching is less than or equal to the length of described insulation layer.
Because the part that ablation needle stretches out needle handle is longer, ablation needle rigidity is less, better can limit each ablation needle and relatively bends by arranging the second fixed block or tilt; Second fixed block is slidably arranged on each ablation needle, structure can be made comparatively simple, do not need special technique for fixing or structure; By arranging spacing line, can prevent the second fixed block from moving to working area, affecting ablation needle work.
Second fixed block have four respectively for corresponding ablation needle pass through hole.
Further, the spacing range between each row of ablation needle is: 5 ~ 8mm; Spacing range between each row is: 5 ~ 8mm.Distance comparatively conference affects radio frequency operation, and apart from too small, ablation range is less.
The beneficial effects of the utility model are: four ablation needles designs being two row and two row and arranging, and can strengthen ablation range, make the time of melting shorter, thus reduce operation risk; First fixed block with through hole can fix each ablation needle, and ensures the relative distance of each ablation needle; Each ablation needle can be fixed preferably by arranging the second fixed block, preventing ablation needle from relatively bending or tilting, thus ensure the reliable also steady operation of ablation needle.
