Novel Vibration Force Sensor with Hepatic Feedback for Minimal Invasive Surgery

Technology Benefits

Attachable to any tool Less expensive than market alternatives Adaptable to existing endo-wrist instruments Most currently existing surgical robotic arms do not feature any haptic feedback

Technology Application

The Vibration Force Sensor can be used in many types of robotics and sensory applications. Particularly, the sensor can be used to give a sense of “touch” to robotic laparoscopic surgical arms. This allows the doctor to “feel” the environment around which they are operating. This invention can also be used on any structure with an anisotropic moment of inertia.

Detailed Technology Description

Researchers at UC San Diego have created a Vibration Force Sensor that provides haptic feedback to the surgeon operating on tele-operated surgical systems during minimally invasive surgery.This feedback includes the magnitude and direction of force applied onto the end effector of the instrument. The Vibration Force Sensor can be attached to any tool head the doctor desires and is orders of magnitude less expensive than other force sensors. With this invention, the surgeon will be better aware of the interactive forces between the surgical tool and the patient’s tissues and organs, thereby improving the safety and accuracy of the surgery.
