Abstract: A bone connection system for attaching a surgical robot having its base mounted in the vicinity of a patient, to a bone of the patient. The system incorporates a switchable bone connection unit attached between the bone and a support element of the robot. This unit has a locked state in which the bone is attached essentially rigidly to the support element, and a released state in which the bone can move relative to the support element. The unit comprises a force sensor for determining the force exerted between the bone and the support element of the robot, and a position sensor for measuring the position of the bone relative to the support element of said robot. The unit switches from its locked state to its released state when the force exceeds a predetermined level, selected to ensure that the bone can move without detaching any bone connection elements.

Abstract: Automatic dilator devices for generating minimally invasive access apertures for surgical procedures or endoscopic surveillance. The automatic dilators comprise a number of spreader tubes nested one inside the other. The devices deploy automatically by means of coupled mechanical mechanisms which insert one spreader after the other distally into the patient's tissue. Each spreader moves distally into the tissue by means of a screwing action, by which rotation is converted into linear motion of the neighboring spreader, immediately external to it, by means of interaction between a helical thread form on a surface of a spreader being engaged by a section of thread, or by one or more protrusions on the opposing face of the next spreader external to the rotating spreader. Such a combination of helical thread and follower enables a rotatory mechanism to be used to deploy one nested spreader tube after the other, by continuous rotary motion.

Abstract: A robotic surgical system comprising at least two robotic arms having co-ordinate systems known relative to each other, one of the arms carrying an X-ray source, and the other an imaging detector plate. The arms are disposed to enable an image to be generated on the region of interest of a subject. One of the arms can additionally or alternatively carry a surgical tool or tool holder, such that the pose of the tool is known in the same co-ordinate system as that of an image generated by the X-ray source and detector. Consequently, any surgical procedure planned on such an X-ray image can be executed by the tool with high accuracy, since the tool position is known in the image frame of reference. This enables the surgeon to accurately position his tool in a real-time image without the need for an external registration procedure.
