Friction Transmission with Axial Loading

C03171: Mechanical Power Converter

Novelty:

An actuator that converts rotational to translational motion and vice versa. The unique design allows for more power transmission than traditional designs of a similar size.

Value Proposition:

Percutaneous procedures have become commonplace in medicine as they are less invasive and result in shorter recovery times. Assistive robotic devices are gradually being introduced in a number of such procedures to improve overall efficacy and minimize damage to other organs. However, many of these solutions can be expensive and cumbersome, thereby significantly inhibiting their adoption. This technology provides improvements in driving power, without needing to increase the size of the device. Other advantages include:

Technical Details:

Johns Hopkins researchers have devised a new approach to converting rotational actions into translational movement. An intended application for this device is to provide an improved needle driving mechanisms for percutaneous medical procedures. Increased power and force transmission achieved by this technology would allow for miniaturization of current products.

Looking for Partners:

To develop and commercialize the technology as a new mechanism for devices in the Robotic Surgery Market, with specific applications in Biopsy, Therapeudic Injections, and Percutaneous surgery.

Stage of Development:
