Abstract

The invention discloses a control device for achieving C arm system follow-up motion. The control device comprises active driving elements, an auxiliary control handle, an infrared switch and a force sensor. All joints of a C arm system are provided with the active driving elements, the auxiliary control handle is connected with the C arm system through the force sensor, and the infrared switch is arranged on the auxiliary control handle. In the starting state, the force sensor obtains operating intentions and transmits commands to the active driving elements of all the joints, and the active driving elements drive the joints of the C arm system to move. According to the control device for achieving C arm system follow-up motion, an operator only needs to apply a little force to flexibly and naturally operate a C arm so as to accurately complete expected motion and positioning according to the will of the operator, and therefore intuitive, simple, accurate and efficient operation is achieved.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a control device and a control method for realizing the follow-up motion of a C-arm system. Background technique

[0002] The C-arm X-ray machine is mainly used for intraoperative X-ray imaging. It is an important tool in clinical treatment such as vascular intervention and spinal surgery. Or real-time update display on intraoperative images, which has very important clinical application value. The function of the C-arm is inseparable from motion and positioning. In many cases, the C-arm is connected to one end of the movable arm. In such cases, the C-arm can typically be raised and lowered, moved from side to side, or rotated about one or more axes of rotation. Thus, such a C-arm can be moved and repositioned to take X-ray images from different positions and angles without requiring patient movement. At present, the main operation methods on the C-arm include active and passi...
