Summary
This study introduces a virtual motion compensation technique to stabilize surgical site images during robotic assisted minimally invasive beating heart surgery, enhancing precision for delicate tasks like anastomosis.
Area of Science:
- Robotics
- Medical Imaging
- Surgical Technology
Background:
- Robotic assisted minimally invasive beating heart surgery presents challenges due to cardiac motion, hindering precise surgical tasks.
- Delicate procedures like small vessel anastomosis are particularly difficult with the heart's rhythmic movement.
Purpose of the Study:
- To propose a virtual motion compensation scheme for stabilizing surgical site images.
- To improve surgical performance in beating heart procedures by providing a stable visual field.
Main Methods:
- Utilizes vision-based 3D tracking to infer cardiac surface deformation.
- Employs augmented reality to render a motion-stabilized surgical view.
- Does not require fiducial markers and integrates with existing robotic systems.
Main Results:
- Validated with simulated surgical scenes and in vivo data from a TECAB procedure.
- Demonstrated improved precision and repeatability for microscale tasks in a moving reference frame.
Conclusions:
- The proposed virtual motion compensation technique shows significant potential for enhancing surgical precision.
- This method offers a viable solution for complex microscale surgical tasks in dynamic environments.
