Estimating the force feedback applied to the forceps.

Conventional surgical robots relied solely on visual information obtained from camera images. Saroa is equipped with a system that estimates the gripping force based on control information and provides feedback to the remote operation interface.
Saroa enables safe and high-precision surgery by providing force feedback, without relying on the operator's experience or intuition.

Information Presentation by Navigation Monitor

In addition to the main monitor that displays images from the endoscope, Saroa’s surgeon console is equipped with a navigation monitor that displays various operational information.
Force information is also displayed as quantitative values (in Newton) and visual information in the form of bar graphs.
This operational information can also be provided to doctors and nurses other than the operating surgeon.

By adopting pneumatic drive, Saroa achieved a lightweight and compact design. This makes it easy to move between operating rooms and within the facility, allowing for more flexible operation.

The Saroa's arm operates with pneumatic control, which is Riverfield's core technology, to achieve delicate and soft movements. It can absorb the load on the patient caused by the machine's inherent stiffness, enabling safe surgical operations.
Pneumatic control technology has succeeded in slimming down the arm body. There is enough space for assistants to be in close proximity to the robot, considering the safety of medical personnel.

Saroa can be used in combination with endoscopes, monitors, and electrocautery equipment from various manufacturers. Since Saroa can use equipment already owned by the hospital, it also contributes to reducing the cost of installation.
