Abstract
A flexible surgical tool system includes: a mechanical arm (10) comprising a first continuum segment (12), a rigid connection segment (13), and a second continuum segment (14), the first continuum segment (12), a rigid connection segment (13) and the second continuum segment (14) being sequentially associated to form a dual continuum mechanism; a surgical effector (50) connected at distal end of the second continuum segment (14); a transmission driving unit (20) associated with the rigid connection segment (13) and with a surgical effector (50), respectively, and operable to drive the first continuum segment (12) to bend in any direction to drive the second continuum segment (14) to bend in an opposite direction, and to drive the surgical effector (50) to rotate in a first plane and/or open and close in a second plane. The flexible surgical tool system can be applied to a natural orifice or a single surgical incision of a human body and perform operations.
