AI Technical Summary

Technical Problem

Current grippers in robotic systems, particularly in medical robotics, struggle to accurately grasp and center instruments of various diameters and non-circular shapes, which is crucial for precise robotic surgical procedures.

Method used

A gripper with an integrated concentric shutter mechanism that can open and close like a conventional gripper, allowing it to accommodate instruments of different diameters and shapes by centering them within the gripper, regardless of their dimensions or circularity.

Benefits of technology

The gripper enables accurate deployment and operation of instruments in robotic surgical procedures by consistently centering the instrument within the gripper, ensuring precise targeting and movement, even with instruments of varying dimensions and shapes.

Abstract

A gripper for holding surgical instruments is provided. The gripper incorporates a concentric and adjustable shutter mechanism that enables the gripper to hold instruments with multiple different circumferences and instruments that do not have a perfect circular circumference. In the context of a robot system that is adjusted uniformly, particularly a surgical robot system, the disclosed gripper enables the robot system to deploy a wide variety of surgical instruments regardless of their circumferences or precise circumferential dimensions. Due to the concentric shutter design, the robot system using the gripper of the present invention can deploy a wide variety of instruments while keeping the instruments always centered within the working area.
