Systems and methods for performing minimally invasive surgical procedures, especially for removal of tumors, and especially for brain tumors, using a robotically inserted therapeutic probe, which first detects tumorous tissue on a pre-planned path through the patient's tissue, before performing therapeutic procedures on the tissue, such as ablation. This pre-treatment detection procedure is thus able to avoid the destruction of healthy tissue. This also ensures that the therapeutic process indicated in a preoperative surgical plan is only performed on tumorous tissue, without sole reliance on preoperative image indications. This is important for neurosurgical operations performed on the brain, since preoperative images may not be accurate due to brain shift occurring during the procedure. Detection can be performed optically or ultrasonically, and treatment by laser or RF ablation. The probe insertion can be performed at 90° to the insertion axis of the device, thus minimizing passage through healthy tissue.
