A Prospective Study of a Haptic Device Evaluation of the Acute Abdomen

A Prospective Study of a Haptic Device Evaluation of the Acute Abdomen


Lead Sponsor: Michigan State University

Source Michigan State University
Brief Summary

The study hypothesis is a haptic sensor can aid in the evaluation of the acute abdomen. Investigators from the MSU Department of Surgery in Collaboration with MSU Engineering are assessing the ability of a non invasive, optical device that is placed on a patients abdomen (much like an ultrasound transducer) to evaluate a patient with an acute abdominal presentation. Conditions such as appendicitis, cholecystitis, diverticulitis or small bowel obstruction will be examined with the haptic device. Data will be collected by the device and later compared to the abdominal findings recorded from an examination conducted by the principle investigator who is a surgeon. The surgeon will not have acess to data collected by the haptic sensor and therefore it will have no impact on the decision making process in the care of the patient. The impact on the individual patient will require obtaining a consent to participate in the study, a few minutes to place the device gently on the abdomen and collect the sensor data. There is no direct benefit to the patient by participating in the study. The potential for such a study may be to develop the technology to have a device that non-medical staff can use to collect patient data and transmit that data to a healthcare provider at another location.
