Embodiment Construction

[0066] now refer to figure 1, which schematically illustrates an exemplary embodiment of a robotically controlled neurosurgical device according to the novel designs presented in this disclosure. In a novel arrangement, the inner flexible needle probe 4 has a combined detection and treatment module 8 at its distal end. Further construction and operational details of various embodiments of this detection and treatment module are shown below. Other features are the outer trocar 3 , the various components used to fix the device on the subject's skull, and the robotically controlled mechanical movement of the probe 4 . The latter comprises a base part 2 rotatably mounted on a main base 1 which is to be fixed to the subject's skull. The rotation of the base part 2 around the main base 1 can be carried out by means of a robotic starter motor 5 (which should also contain an angular position encoder), so that the angular orientation of the base part 2 is determined. Known.

Abstract

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 onpreoperative 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 degrees to the insertion axis of the device, thus minimizing passage through healthy tissue.

Description

technical field [0001] The present invention is in the field of systems and methods for performing robotically controlled minimally invasive surgical procedures, especially for resection of tumors, and especially for brain tumors, and which systems and methods include Preliminary study of the nature of the area. Background technique [0002] In U.S. Published Patent Application No. 2014 / 0025088, which is a common inventor with the present application, a robotic device for performing minimally invasive neurological procedures is described that uses a cannulated needle for insertion into In the skull tissue, the hollow needle has a flexible inner needle coaxially arranged in the hollow needle, and can leave the hollow needle at an angle of up to 90° with the axis of the hollow needle, so as to be able to access the Tissue on the side of the exit hole of the device. Rotation of the hollow needle enables access to tissue disposed at any angular orientation to the hollow needle...
