This technology is a surgical robot mechanism that utilizes a leaf spring-type drive transmission unit within a multi-joint positioning unit. By adjusting the bending and straightening of the leaf spring based on the tensile force of the drive unit, it controls joint positioning and generates high driving torque.
Conventional wire-based drive transmission methods struggle to provide the sufficient torque required for manipulating internal organs and face physical limitations regarding the surgical workspace and power transmission accuracy.
Instead of wires, this technology places a leaf spring-type drive transmission unit on one side of the joint and controls it via a drive unit, increasing mechanical rigidity to deliver high torque. A guide member ensures precise, stable operation without displacement. Applicable to surgical robots, interventional systems, and medical automation, it improves procedural accuracy and ensures precise drive transmission, thereby reducing the burden on the patient.
This invention was developed with support from the Ministry of Education, Science and Technology's TOP Campus Construction project.
