An articulated arm is disclosed which can be used to firmly support and position a variety of medical tools, including surgical or diagnostic instruments flexibly in space. Though some of its sub-assemblies may be computer controlled, thus autonomous in accordance to some pre-programmed sequence, manual control is also possible. When its sub-assemblies are suitably controlled using computer software, and with a suitable cutting instrument, the arm is capable of generating a barrel shape cavity or, for that matter, any desired shape of cavity (or treatment volume) that is within the work envelope of the arm. The ideal position of the focal point is dynamically variable as required, either with respect to the tool or the absolute frame of reference, during an intervention. A suitable type of intervention is minimally invasive surgery (MIS). Apart from cutting (or resection), the articulated arm, by virtue of its robotic nature, can also be used to perform such tasks as biopsies and radiation seed implantation, where positional accuracy and repeatability are highly desirable. The articulated arm is a universal computer assisted holder for a wide range of medical tools, in particular endoscopes for treatment of urological disorders.

[ It is claimed:] [1.] An articulated arm for performing medical procedures with a medical tool, the arm comprising:an arcuate member slidably mounted on a first movable support member;a tool holder for holding the medical tool in an operational position, said tool holder being carried by the arcuate member; and,a first drive assembly provided on said first support member for slidably moving said arcuate member with said tool holder, wherein said tool holder can be moved along an arcuate path so as to alter the operational position of the tool in a predetermined manner,and wherein said arcuate member is removably mounted on said first support member, and wherein another arcuate member having a different radius of curvature can be slidably mounted on the first support member.
