Stand device responsive to force or movement, control device, and method for positioning the stand device

A stand device for arranging in an operating room and for locally moving a medical device, comprising:

• at least one movably mounted support arm;
• a braking device having at least one brake that is configured to adjust a degree of freedom of movement of the at least one support arm and/or the medical device relative to a supporting device;
• a control device connected to the braking device;
• and
• at least one sensor device connected to the control device, the at least one sensor device being configured to detect an external force acting on the stand device or a movement caused by the external force and configured to output a corresponding measured value to the control device, wherein the control device is configured to control the braking device as a function of the measured value, the controlling including completely releasing the braking device when the external force exceeds a certain threshold value and reactivating the braking device when the external force reduces to, or less than, the certain threshold value, as a function of the measured value autonomously and without operating an additional switch based only on the external force acting on the stand device, the complete releasing causing adjustment of the degree of freedom of movement of the at least one support arm and/or the medical device relative to the supporting device.
