A medical instrument, particularly a surgical instrument with a displaceable push/pull activation tube arranged on the proximal end of a hand manipulator, that also contains an inner tube for retaining a fixed jaw, for activating remote tool parts on the distal end, in which a force-limiting device limits the transmission of force to the remote tool parts from the hand manipulator via an extendable coil spring. The medical instrument optionally features a fiber scope to enable optical viewing to locate the implanted device for removal as well as a saline flush capability. The instrument has jaws that are cylindrical in shape to facilitate grasping an implanted cylindrical device.
