Abstract

A surgical robot system and a flexible surgical instrument are provided. The flexible surgical instrument includes a flexible instrument and an instrument driving apparatus capable of outputting a driving force to the flexible instrument. An instrument conveying unit of the flexible instrument includes a housing and an instrument storage device. A spiral accommodating groove is formed on the outer circumferential surface of the instrument storage device to wind and store a flexible body of an actuator unit, and the instrument storage device can rotate and move axially relative to the housing of the flexible instrument. A transmission unit includes a transmission substrate in transmission connection with the instrument driving apparatus, and the transmission substrate is connected to the instrument storage device to drive the instrument storage device to rotate and move axially relative to the housing.
