Medical Robot

This technology is a medical robot system that focuses radiation on a target point from multiple angles through the relative movement between a bed and a multi-link robotic arm unit that follows a spherical trajectory.

Existing robot-based treatment equipment has faced limitations in targeting accuracy, prolonged treatment times, increased weight due to complex drive mechanisms, and the risk of collisions when using multiple robotic arms.

This technology features a configuration of multiple links and drive members that follow a spherical trajectory centered on the same point, allowing for independent multi-axis rotation control through vertical and horizontal relative movement between the bed and the robotic arm unit. By adjusting the bed's position, it optimizes targeting efficiency for the target point. Applicable to industrial robots and automation systems, it improves the accuracy and efficiency of radiation therapy for cancer treatment, enabling rapid and precise targeting, simplifying control, and reducing treatment or operation times.

Key Features:

• A bed on which the subject is positioned
• A robotic arm unit equipped with an emission member capable of moving within a spherical trajectory where the target point is located at the center of the sphere
• The bed and the robotic arm unit are capable of relative movement in vertical or horizontal directions
• A configuration that moves the subject to the target point by causing relative movement between the bed and the robotic arm unit
