A miniature surgical robot and a method for using it are disclosed. The miniature surgical robot attaches directly with the bone of a patient. Two-dimensional X-ray images of the robot on the bone are registered with three-dimensional images of the bone. This locates the robot precisely on the bone of the patient.

A method for controlling a surgical robot includes calculating an external force acting on a robot arm mounted with a surgical instrument, filtering the external force acting on the robot arm when a central point of an incision is set, calculating a virtual force to enable the surgical instrument which is positioned away from the central point of the incision to return to the central point of the incision, and applying the calculated virtual force to the filtered external force, to control movement of the robot arm. As a result, it is possible to compactly design the surgical robot and thereby reduce the volume of the surgical robot.

A robotic surgical system incorporating a surgical robot attached to a patient's bone by an attachment member, such that motion of the bone induces corresponding motion of the robot, maintaining the robot / bone positional relationship. The robot is supported on a mechanical mounting member attached through a controlled joint to a bed-mounted base element. The controlled joint can alternatively enable the mechanical mounting member to move freely relative to the base element, or its position can be controlled by signal inputs adapted to prevent excessive force being applied in the system. Two modes of operation are available (i) free motion in which the control system is decoupled from the mounting member, which rides freely with patient bone motion, and (ii) servo-controlled motion, in which drive mechanisms control the joint motion to prevent application of excessive force on the patient bone or attachment member.

This invention proposes a robotic applicator device to be deployed internally to a patient having a capsule (also referred to as a cassette) and aperture with a means of alternately occluding and exposing a radioactive source through the aperture. The capsule and aperture will be integrated with a surgical robot to create a robotic IORT (intra-operative radiation therapy) applicator device as more fully described below. The capsule, radiation source, and IORT applicator arm would be integrated to enable a physician, physicist or technician to interactively internally view and select tissue for exposure to ionizing radiation in sufficient quantities to deliver therapeutic radiation doses to tissue. Via the robotic manipulation device, the physician and physicist would remotely apply radiation to not only the tissue to be exposed, but also control the length of time of the exposure. Control means would be added to identify and calculate margin and depth of tissue to be treated and the proper radiation source or radioactive isotope (which can be any particle emitter, including neutron, x-ray, alpha, beta or gamma emitter) to obtain the desired therapeutic effects. The invention enables stereotactical surgery and close confines radiation therapy adjacent to radiosensitive tissue.
