A biopsy tool for MR imaging for operation by a robot arm is formed of relatively brittle ceramic materials which have a magnetic susceptibility which is substantially equal to that of human tissue. The tool has designed slip couplings and bend joints to prevent overloading of forces on the sampling jaws. Cleaning ports are integrated into the design so that sterility can be obtained by flushing the device interior with a cleaning fluid.
