Abstract
Provided is a surgical instrument capable of reverse drive. The surgical instrument includes: an end tool having at least one driving element activated by a wire; a power transmission unit that controls a linear movement of the wire based on a rotational movement of a conversion element in accordance with power from an actuator; and a shaft connecting the end tool and the power transmission unit. The surgical instrument is configured so that both forward drive in which the driving element is activated according to activation of the actuator and the reverse drive in which the conversion element is activated according to activation of the driving element due to an external force are possible.
