NZ519815A - Device for moving a medical apparatus in a controlled manner - Google Patents

Abstract

The apparatus relates to the moving of an X-ray apparatus in a controlled manner. The apparatus is embodied as a C-bow (9) that can be displaced in parallel in relation to at least two axes (18; 19) and is mounted on a pedestal (31) in a rotatable manner in relation to three axes (18; 19; 21). Said pedestal comprises rollers (3) which can be driven by a motor. The direction of said rollers can be controlled. Each movement of the C-bow (9) is carried out in relation to a system of co-ordinates (29) and by means of controllable drive devices (6; 7; 37; 38). Said system is stationary in relation to the room. The drive devices (6; 7; 37; 38) are controlled by means of a computer (23) or a control device (39; 48) which can be controlled by means of a sterile control console or is voice-controlled. Adjusted positions or projections of the C-bow (9) can be stored in the computer (23) in such a way that a desired position or projection can be reproduced. The C-bow (9) can be combined with a surgical navigation system which comprises a position detection device (27). By measuring a reference base (51) that is provided with optical markers (28) and is applied to a patient (12) changes in the position of the patient (12) can thus be considered in such a way that an adjusted position and projection of the C-bow (9) can be reproduced after the patient (12) has changed position.
