FIELD: medicine.
SUBSTANCE: invention relates to medicine and can be used in operations on digestive system. Surgical instrument is functionally intended for spreading of anastomosis ring device. Instrument contains ring spreading mechanism, made with possibility of inclusion and spreading of anastomosis ring by working effort. Instrument additionally contains electroactive polymer, which is made with possibility to take voltage from power source. Electroactive polymer is made with possibility to transform voltage into working effort. Electroactive polymer is made with additional possibility of working effort application on ring spreading mechanism in order to spread anastomosis ring.
EFFECT: improvement of surgical instrument characteristics.
