As part of the paper, the idea of designing and developing an automated tool to be used in the field of medical robotics, was presented in detail. The starting point was the intention to fully automate the increasingly complex and widespread biopsy procedure of the patient's brain tissue, which is performed by a surgeon in the presence of a robot. Thus, through the work, the existing robotic technologies and the appropriate tools that were developed for the purpose of performing automated neurosurgical procedures were first presented in detail. This is followed by the initial design of the biopsy tool idea and the presentation and review of the most important functional features that the robot tool should be able to fulfill. The summarization of the functions and potential mechanical and electrical elements from which the tool could be assembled, subsequently led to the formation of the first concepts. The iterative development process, as well as the individual refinement of each of the conceptual design solutions, led to the gradual creation of the final version of the tool for the automated neurosurgical biopsy of brain tissue. The mechanical model of the final concept was then accompanied by a detailed deconstructive breakdown into the individual parts of which it was composed. Thus, all the functional roles of each part are furthermore described and all the processes of thinking and reasoning, that led to the creation of the robotic tool, are listed and explained. In the end, the implementation and production of a functional robotic tool was carefully presented and a conclusion was reached on the given topic. Through the conclusion, all the achievements during the conceptual development of the robotic tool were evaluated and potential improvements were proposed in order to further contribute to the growing trend of automation and shortening the duration of surgical procedures in the area of the brain, using robotic technology in the field of medicine.
