Surgical robots are used in the field of minimally invasive surgery that is beyond human capabilities to achieve precision operations that cannot be completed by human capabilities alone. Surgical robots are often equipped with energy surgical instruments to perform operations such as cutting, separation, and hemostasis of tissues during surgery. These instruments emit high-frequency, ultrasonic, microwave and other energies, interact with living tissues, and achieve precision surgery. However, different energy instruments are required for tissue stripping and hemostasis operations in existing surgical operations.
