AI Technical Summary
Among existing surgical robotic instruments, winch actuators are expensive and complex, while linear actuators are difficult to precisely tension steel bar bundles, posing challenges in manufacturing and use, especially in minimally invasive surgery.
A combination device consisting of multiple counterweights, primary pulleys, secondary pulleys, and tensioning wires is used to tension the steel reinforcement bundles by suspending the tensioning wires through the counterweights, and auxiliary pulleys are used to optimize the path to ensure that the steel reinforcement bundles extend in a parallel and compact manner.
It enables precise and repeatable tensioning of multiple steel bar bundles, simplifies the manufacturing and maintenance process, reduces costs, and improves the reliability and consistency of the equipment.
