Abstract
A surgical robot system, a control method and a computer-readable storage medium can be used with or for a surgical procedure on a patient. The system can include at least one patient fixation unit adapted to be rigidly and directly attached to the patient to rigidly fix at least one body part of the patient with an intervention region relative to the patient fixation unit. At least one controllable surgical robot has a robot base directly connected to the patient fixation unit, and a movable robot arm connected to the robot base. An end effector, in particular a surgical instrument, can be connected to, in particular mounted on, the robot arm, in particular to a terminal side of the robot arm.
Claims15
A surgical robot system for surgical intervention on a patient, comprising:
- at least one patient fixation unit which is adapted to be rigidly and directly attached to the to a head of the patient, in order to rigidly fix at least a body portion of the patient with an intervention region relative to the at least one patient fixation unit;
- at least one surgical robot that is controllable, the at least one surgical robot comprising a robot base, which is directly connected to the at least one patient fixation unit, as well as a robot arm that is moveable and connected to the robot base and an end effector;
- and
- a surgical navigation system for navigating the end effector.
A control method for a surgical robot system that includes a robot, the control method comprising the steps of:
- creating, via an optical image device, an optical image of an intervention region of a patient together with an end-effector tip of a robot-guided end effector, wherein the robot is directly connected to a patient fixation unit rigidly connected to the patient, and providing the optical image;
- providing, via a data provision unit, digital 3D image data of the patient;
- tracking, via a tracking system, of at least the optical image device and a body portion of the patient fixed relative to the patient fixation unit;
- determining, via a control unit, a position of the end-effector tip relative to the optical image device by machine vision based on the basis of the optical image;
- creating, via the control unit, an overlapping with the digital 3D image data and the position of the end-effector tip;
- and
- outputting the overlapping as an overlapping representation by a display unit and/or controlling the robot-guided end effector based on the overlapping.
