Method for generating force feedback of remote surgical device

The present invention is a method for controlling a Davinci surgical device. Firstly, controlling an operation part of a remote operation device to enter the inner of a body for executing a surgical operation. Then, an image capturing unit captures a plurality of corresponding surgical images to a control device, and the control device obtains a first torque, a second torque and a element action of the remote surgical device according to the surgical images to operate a output strength of the remote surgical device for further generating a corresponding strength feedback by the output strength. Thus, the user can get the control status of the remote surgical device to prevent accidental iatrogenic injury from over-force and to proceed the operation with improved accuracy.
