An integrated ablation needle (100), comprising a cannula (10) and an electrode needle (20) that is movably and penetratingly installed within the cannula (10); the electrode needle (20) comprises a needle tip (21) located at the far end and a needle rod (23) connected to the near end of the needle tip (21); at least a portion that is near to the needle tip (21) of the needle rod (23) is provided with a sampling groove (231); and the far end of the cannula (10) is provided with a cutting edge (11). The cannula (10) moves along the axial direction relative to the needle rod (23) so as to expose or cover the sampling groove; when the sampling groove (231) is exposed, a tissue portion around the needle rod (23) enters the sampling groove (231); and when the sampling groove (231) is covered, the cutting edge (11) cuts off tissue inside and outside of the sampling groove (231), such that the tissue within the sampling groove (231) is acquired as a biopsy sample. Further provided is an ablation system (1000) comprising an integrated ablation needle (100). The integrated ablation needle (100) and the ablation system (1000) integrate ablation and biopsy functions on the same ablation needle (100), without needing to independently execute a biopsy step, thus avoiding repeated puncturing, reducing damage to the human body, and reducing operation time.
