Double-Bending Flexible Surgical Tool System
Summary
USPTO granted Patent US12599374B2 to Beijing Surgery Robotics Company Limited for a double-bending flexible surgical tool system. The system includes a mechanical arm with four continuum segments forming two dual continuum mechanisms, driven by a transmission unit to enable opposing bending movements. The patent contains 13 claims and covers surgical robotics technology for enhanced precision in surgical procedures.
What changed
USPTO granted Patent US12599374B2 for a double-bending flexible surgical tool system invented by Kai Xu, Jiangran Zhao, Linhui Niu, Yi Sun, and Jing Zhu. The system comprises a mechanical arm with first, second, and third continuum segments connected by a rigid segment, forming two dual continuum mechanisms that enable independent opposing bending movements through a transmission driving unit.
For medical device manufacturers and surgical robotics developers, this patent establishes intellectual property protection for dual continuum mechanism designs in flexible surgical tools. Entities developing similar robotic surgery systems should review this patent for potential freedom-to-operate considerations or licensing opportunities with Beijing Surgery Robotics Company Limited.

Abstract
A double-bending flexible surgical tool system includes a mechanical arm including a first continuum segment, a rigid connection segment, a second continuum segment, and a third continuum segment. The first continuum segment and the second continuum segment are associated to form a first dual continuum mechanism. A proximal continuum segment disposed at a proximal end of the first continuum segment and associated with the third continuum segment disposed at a distal end of the second continuum segment form a second dual continuum mechanism. A transmission driving unit associated with the rigid connection segment and the proximal continuum segment, respectively, is configured to drive the first continuum segment to bend in any direction to drive the second continuum segment to bend in an opposite direction, and to drive the proximal continuum segment to bend in any direction to drive the third continuum segment to bend in an opposite direction.
