Summary
This study demonstrates the feasibility of robotic-assisted supermicrosurgery for delicate vessel anastomosis. The Symani Surgical System offers enhanced precision, potentially expanding microsurgical capabilities for complex reconstructions.
Area of Science:
- Surgical Technology
- Robotics in Medicine
- Microsurgery
Background:
- Microsurgery is crucial for complex procedures like tissue reconstruction and allotransplantation.
- Increasingly complex microsurgical techniques require enhanced precision and tremor reduction.
- Robotic assistance offers potential solutions for motion scaling and tremor reduction in microsurgery.
Purpose of the Study:
- To evaluate the feasibility of a novel robotic platform for supermicrosurgical anastomosis.
- To assess the application of robot-assisted microsurgery in free flap reconstruction.
Main Methods:
- Utilized the Symani Surgical System for robot-assisted microsurgical free flap reconstruction.
- Performed robot-assisted anastomosis of an artery and vein less than 0.8 mm in diameter.
- Employed a perforator-to-perforator flap technique.
Main Results:
- Successful completion of robot-assisted arterial and venous anastomosis.
- Vessels remained fully patent immediately and 20 minutes post-anastomosis.
- Flap viability was maintained, with no need for re-exploration or flap loss.
Conclusions:
- The Symani Surgical System is feasible for robot-assisted anastomosis in supermicrosurgery.
- Robotic assistance with wristed instruments can overcome manual precision limitations.
- This technology may broaden access to microsurgery and enable new applications.
