Abstract

An electromagnetic damping precession force feedback operating handle for vascular intervention is characterized in that the operating handle comprises an operating lever (8), and a frame (22), and also includes any one or more mechanisms of a push-pull force feedback mechanism , a rotational torque feedback mechanism, a rotational movement measuring mechanism, and non-contact reset mechanism which are mounted on the operating lever (8); the operating handle (8) is supported on the frame (22) by a left linear bearing (9), a right linear bearing (17), and the operating lever (8) is made of ferromagnetic material. The operating handle can realize the control command issuance of push-pull, rotation and clamping as well as the resistance feedback, adopts the non-contact design except the linear bearing support, and has the characteristics of strong function, light operation and compact structure.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to an electromagnetic damping force feedback operating handle for vascular intervention, and in particular to a damping force generated by an electromagnetic actuator and fed back to the handle to generate tactile sensation, and a displacement sensor, a rotation angle measurement sensor, a force The sensor assists in completing the operation handle for clamping, pushing, and rotating control of catheters and guide wires. Background technique [0002] In vascular interventional surgery, doctors need to receive X-ray radiation for a long time, so a remote operation interventional surgery robot has been developed for engineering. The interventional surgery robot works in the radiation environment, and the doctor controls it outside the radiation environment. At present, there are two control methods, one is the touch screen, and the other is the operation handle. On the one han...
