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 component, a second torque component and an element action of the remote surgical device according to the surgical images to operate an output strength of the remote surgical device for further generating 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 with the operation with improved accuracy.

Robotic System And Method For Removing A Volume Of Material From A Patient

A tool path generator utilizes a solid body model of a volume to generate a tool path for a manipulator to remove material of the volume with an energy applicator in a semi-autonomous mode. A material logger monitors movement of the energy applicator according to a cutting path taken by a practitioner in the manual mode, identifies material of the volume to which the energy applicator has been applied in the manual mode, and updates the solid body model based on the identified material. The tool path generator modifies the tool path based on the updated solid body model such that, for the semi-autonomous mode, the modified tool path accounts for the identified material of the volume to which the energy applicator has been applied in the manual mode.

20220032473 · 2022-02-03 ·

A method of controlling a robotic arm in a surgical system comprises manually applying a force to a body of the robotic arm. Force information is received from ae force sensor on the robotic arm and a controller determines, using the force information, whether the force is a gesture force input. If the force is determined to be a gesture force input, the controller initiates electromechanical movement of the manipulator arm to a draping configuration, instrument attachment configuration, storage configuration, or home configuration.
