Developable/Fully Collapsible External Gripping Mechanism ID: 2018-046

An innovative mechanism designed to perform multiple functions through a single entry point in confined spaces.

Technology Overview

This technology introduces a unique external gripping mechanism that integrates a cylindrical shaft with curved-link, four-bar mechanisms. These components actuate to grip and manipulate objects from the outside, offering a versatile solution for operations in restricted environments. The invention is available in two embodiments: one featuring a single cylinder with dual four-bar mechanisms, and another utilizing two concentric cylinders with intermittent actuation. This design is particularly advantageous for applications requiring minimal intrusion, such as minimally invasive surgery and precision drilling.

Key Advantages

• Enables multiple functionalities through a single entry point, reducing the need for multiple penetrations in confined spaces
• Offers a compact and fully collapsible design, enhancing portability and ease of use
• Improves precision and control in manipulating objects in restricted environments
• Potential for wide application in medical, industrial, and exploratory fields

Problems Addressed

• Reduces the complexity and invasiveness of operations in confined spaces
• Minimizes the risk of damage to surrounding areas in sensitive environments
• Overcomes limitations of existing tools by providing enhanced functionality and flexibility

Market Applications

• Minimally invasive surgical instruments for healthcare
• Down-hole drilling equipment for oil and gas exploration
• Robotic tools for industrial maintenance and repair
• Exploratory devices for space and underwater research
